Analgesia obstétrica/Obstetric analgesia
Dosis analgésica única intratecal para control del dolor del parto: ¿Una útil alternativa analgésica al bloqueo epidural?
Single-dose intrathecal analgesia to control labour pain: is it a useful alternative to epidural analgesia?

Abstract
OBJECTIVE: To examine the safety and efficacy of single-dose spinal analgesia (intrathecal narcotics [ITN]) during labour. QUALITY OF EVIDENCE: MEDLINE was searched and the references of 2 systematic reviews and a meta-analysis were reviewed to find articles on obstetric analgesia and pain measurement. The 33 articles selected included 14 studies, 1 meta-analysis, and 2 systematic reviews, all providing level I evidence. MAIN MESSAGE: The literature supports use of ITN as a safe and effective alternative to epidural anesthesia. The recent decrease in rates of episiotomies and use of forceps during deliveries means patients require less dense perineal anesthesia. The advantage of single-dose ITN is that fewer physicians and nurses are needed to administer it even though its safety and effectiveness are comparable with other analgesics. Use of ITN is associated with a shorter first stage of labour and more rapid cervical dilation. A combination of 2.5 mg of bupivacaine, 25 microg of fentanyl, and 250 microg of morphine intrathecally usually provides a 4-hour window of acceptable analgesia for patients without complications not anticipating protracted labour. The evolution in dosing of ITN warrants a re-examination of its usefulness in modern obstetric practice. CONCLUSION: Physicians practising modern obstetrics in rural and small urban centres might find single-dose ITN a useful alternative to parenteral or epidural analgesia for appropriately selected patients.

Abstract
PURPOSE: To assess the efficacy of transversus abdominis plane (TAP) block in improving analgesia following Cesarean delivery (CD). SOURCE: We searched MEDLINE, CENTRAL, EMBASE, and CINAHL for randomized controlled trials that assessed the efficacy of TAP block following CD and reported on postoperative pain scores and/or opioid consumption. Studies were combined according to the use or non-use of intrathecal morphine (ITM). Another analysis was performed for studies comparing TAP block with ITM. PRINCIPAL FINDINGS: Nine studies were included. Transversus abdominis plane block significantly reduced opioid consumption (mg morphine equivalents) after Cesarean delivery at six hours (mean difference [MD] -10.18; 95% confidence interval [CI] -13.03 to -7.34), at 12 hr (MD -13.83; 95% CI -22.77 to -4.89), and at 24 hr (MD -20.23; 95% CI -33.69 to -6.77). The TAP block also reduced pain scores for up to 12 hr and nausea in patients who did not receive ITM. When added to ITM, TAP block produced a small reduction in pain scores on movement in the first six hours (MD -0.82, 95% CI -1.52 to -0.11). When compared with ITM, pain scores on movement and opioid consumption at 24 hr were lower (MD 0.98; 95% CI 0.06 to 1.91 and MD 8.42 mg; 95% CI 1.74 to 15.10, respectively), and time to first rescue analgesic was longer with ITM (8 hr vs 4 hr), although opioid-related side effects were more common. CONCLUSION: Transversus abdominis plane block significantly improved postoperative analgesia in women undergoing CD who did not receive ITM but showed no improvement in those who received ITM. Intrathecal morphine was associated with improved analgesia compared with TAP block alone at the expense of an increased incidence of side effects.

Analgesia combinada epidural espinal versus analgesia peridural en trabajo de parto. ¿La analgesia espinal inicial reduce las concentraciones subsecuentes mínimas de bupivacaína peridural?
Combined spinal epidural vs epidural labour analgesia: does initial intrathecal analgesia reduce the subsequent minimum local analgesic concentration of epidural bupivacaine?

Abstract
Labour analgesia initiated using a combined spinal-epidural (CSE) technique may reduce subsequent epidural bupivacaine requirements compared with an epidural-only technique. We compared the minimum local analgesic concentrations (MLAC) of epidural bupivacaine following initial intrathecal or epidural injection. In a prospective, double-blind study, 115 women requesting epidural analgesia were randomly assigned to receive either an epidural with bupivacaine 20 mg and fentanyl 40 μg or a CSE with intrathecal bupivacaine 2.5 mg and fentanyl 5 μg. Analgesia was assessed using a visual analogue pain score. When further analgesia was requested, bupivacaine 20 ml was given, and the concentration was determined using the technique of up-down sequential allocation. The MLAC of bupivacaine in the epidural group was 0.032% wt/vol (95% CI 0.020-0.044) compared with 0.047% wt/vol (95% CI 0.042-0.052) in the CSE group. Bupivacaine requirements for the second injection were increased following intrathecal analgesia by a factor of 1.45 (p = 0.026) compared with epidural analgesia.

Secret Ingredient for Success
By CAMILLE SWEENEY and JOSH GOSFIELD
Published: January 19, 2013
WHAT does self-awareness have to do with a restaurant empire? A tennis championship? Or a rock star’s dream?
Enlarge This Image
Marion Fayolle
David Chang’s experience is instructive.
Mr. Chang is an internationally renowned, award-winning Korean-American chef, restaurateur and owner of the Momofuku restaurant group with eight restaurants from Toronto to Sydney, and other thriving enterprises, including bakeries and bars, a PBS TV show, guest spots on HBO’s “Treme” and a foodie magazine, Lucky Peach. He says he worked himself to the bone to realize his dream — to own a humble noodle bar.
He spent years cooking in some of New York City’s best restaurants, apprenticed in different noodle shops in Japan and then, finally, worked 18-hour days in his tiny restaurant, Momofuku Noodle Bar.
Mr. Chang could barely pay himself a salary. He had trouble keeping staff. And he was miserably stressed.
He recalls a low moment when he went with his staff on a night off to eat burgers at a restaurant that was everything his wasn’t — packed, critically acclaimed and financially successful. He could cook better than they did, he thought, so why was his restaurant failing? “I couldn’t figure out what the hell we were doing wrong,” he told us.
Mr. Chang could have blamed someone else for his troubles, or worked harder (though available evidence suggests that might not have been possible) or he could have made minor tweaks to the menu. Instead he looked inward and subjected himself to brutal self-assessment.
Was the humble noodle bar of his dreams economically viable? Sure, a traditional noodle dish had its charm but wouldn’t work as the mainstay of a restaurant if he hoped to pay his bills.
Mr. Chang changed course. Rather than worry about what a noodle bar should serve, he and his cooks stalked the produce at the greenmarket for inspiration. Then they went back to the kitchen and cooked as if it was their last meal, crowding the menu with wild combinations of dishes they’d want to eat — tripe and sweetbreads, headcheese and flavor-packed culinary mashups like a Korean-style burrito. What happened next Mr. Chang still considers “kind of ridiculous” — the crowds came, rave reviews piled up, awards followed and unimaginable opportunities presented themselves.
During the 1970s, Chris Argyris, a business theorist at Harvard Business School (and now, at 89, a professor emeritus) began to research what happens to organizations and people, like Mr. Chang, when they find obstacles in their paths.
Professor Argyris called the most common response single loop learning — an insular mental process in which we consider possible external or technical reasons for obstacles.
LESS common but vastly more effective is the cognitive approach that Professor Argyris called double-loop learning. In this mode we — like Mr. Chang — question every aspect of our approach, including our methodology, biases and deeply held assumptions. This more psychologically nuanced self-examination requires that we honestly challenge our beliefs and summon the courage to act on that information, which may lead to fresh ways of thinking about our lives and our goals.
In interviews we did with high achievers for a book, we expected to hear that talent, persistence, dedication and luck played crucial roles in their success. Surprisingly, however, self-awareness played an equally strong role.
The successful people we spoke with — in business, entertainment, sports and the arts — all had similar responses when faced with obstacles: they subjected themselves to fairly merciless self-examination that prompted reinvention of their goals and the methods by which they endeavored to achieve them.
The tennis champion Martina Navratilova, for example, told us that after a galling loss to Chris Evert in 1981, she questioned her assumption that she could get by on talent and instinct alone. She began a long exploration of every aspect of her game. She adopted a rigorous cross-training practice (common today but essentially unheard of at the time), revamped her diet and her mental and tactical game and ultimately transformed herself into the most successful women’s tennis player of her era.
The indie rock band OK Go described how it once operated under the business model of the 20th-century rock band. But when industry record sales collapsed and the band members found themselves creatively hamstrung by their recording company, they questioned their tactics. Rather than depend on their label, they made wildly unconventional music videos, which went viral, and collaborative art projects with companies like Google, State Farm and Range Rover, which financed future creative endeavors. The band now releases albums on its own label.
No one’s idea of a good time is to take a brutal assessment of their animating assumptions and to acknowledge that those may have contributed to their failure. It’s easy to find pat ways to explain why the world has not adequately rewarded our efforts. But what we learned from conversation with high achievers is that challenging our assumptions, objectives, at times even our goals, may sometimes push us further than we thought possible. Ask David Chang, who never imagined that sweetbreads and duck sausage rice cakes with kohlrabi and mint would find their way beside his humble noodle dishes — and make him a star.
Camille Sweeney and Josh Gosfield are the authors of the forthcoming book “The Art of Doing: How Superachievers Do What They Do and How They Do It So Well.”

You Are Going to DieBy TIM KREIDER

AGING, DEATH AND DYING,ELDERLY, LONGEVITY,RETIREMENT COMMUNITIES AND ASSISTED LIVING
My sister and I recently toured the retirement community where my mother has announced she’ll be moving. I have been in some bleak clinical facilities for the elderly where not one person was compos mentis and I had to politely suppress the urge to flee, but this was nothing like that. It was a very cushy modern complex housed in what used to be a seminary, with individual condominiums with big kitchens and sun rooms, equipped with fancy restaurants, grills and snack bars, a fitness center, a concert hall, a library, an art room, a couple of beauty salons, a bank and an ornate chapel of Italian marble. You could walk from any building in the complex to another without ever going outside, through underground corridors and glass-enclosed walkways through the woods. Mom described it as “like a college dorm, except the boys aren’t as good-looking.” Nonetheless I spent much of my day trying not to cry.
You are older at this moment than you’ve ever been before, and it’s the youngest you’re ever going to get.
At all times of major life crisis, friends and family will crowd around and press upon you the false emotions appropriate to the occasion. “That’s so great!” everyone said of my mother’s decision to move to an assisted-living facility. “It’s really impressive that she decided to do that herself.” They cited their own stories of 90-year-old parents grimly clinging to drafty dilapidated houses, refusing to move until forced out by strokes or broken hips. “You should be really relieved and grateful.” “She’ll be much happier there.” The overbearing unanimity of this chorus suggests to me that its real purpose is less to reassure than to suppress, to deny the most obvious and natural emotion that attends this occasion, which is sadness.
My sadness is purely selfish, I know. My friends are right; this was all Mom’s idea, she’s looking forward to it, and she really will be happier there. But it also means losing the farm my father bought in 1976, where my sister and I grew up, where Dad died in 1991. We’re losing our old phone number, the one we’ve had since the Ford administration, a number I know as well as my own middle name. However infrequently I go there, it is the place on earth that feels like home to me, the place I’ll always have to go back to in case adulthood falls through. I hadn’t realized, until I was forcibly divested of it, that I’d been harboring the idea that someday, when this whole crazy adventure was over, I would at some point be nine again, sitting around the dinner table with Mom and Dad and my sister. And beneath it all, even at age 45, there is the irrational, little-kid fear: Who’s going to take care of me? I remember my mother telling me that when her own mother died, when Mom was in her 40s, her first thought was: I’m an orphan.
Plenty of people before me have lamented the way that we in industrialized countries regard our elderly as unproductive workers or obsolete products, and lock them away in institutions instead of taking them into our own homes out of devotion and duty. Most of these critiques are directed at the indifference and cruelty thus displayed to the elderly; what I wonder about is what it’s doing to the rest of us.

Segregating the old and the sick enables a fantasy, as baseless as the fantasy of capitalism’s endless expansion, of youth and health as eternal, in which old age can seem to be an inexplicably bad lifestyle choice, like eating junk food or buying a minivan, that you can avoid if you’re well-educated or hip enough. So that when through absolutely no fault of your own your eyesight begins to blur and you can no longer eat whatever you want without consequence and the hangovers start lasting for days, you feel somehow ripped off, lied to. Aging feels grotesquely unfair. As if there ought to be someone to sue.
We don’t see old or infirm people much in movies or on TV. We love explosive gory death onscreen, but we’re not so enamored of the creeping, gray, incontinent kind. Aging and death are embarrassing medical conditions, like hemorrhoids or eczema, best kept out of sight. Survivors of serious illness or injuries have written that, once they were sick or disabled, they found themselves confined to a different world, a world of sick people, invisible to the rest of us. Denis Johnson writes in his novel “Jesus’ Son”: “You and I don’t know about these diseases until we get them, in which case we also will be put out of sight.”
My own father died at home, in what was once my childhood bedroom. He was, in this respect at least, a lucky man. Almost everyone dies in a hospital now, even though absolutely nobody wants to, because by the time we’re dying all the decisions have been taken out of our hands by the well, and the well are without mercy. Of course we hospitalize the sick and the old for some good reasons (better care, pain relief), but I think we also segregate the elderly from the rest of society because we’re afraid of them, as if age might be contagious. Which, it turns out, it is.
Because of all the stories we’ve absorbed, we vaguely imagine that our lives will take the shape of a narrative — the classic Aristotelian ramp diagram of gradual rising action (struggle and setbacks), climax (happy marriage, professional success), and a brief, cozy denoument (kicking back with family and friends, remembering the good times on a porch someplace pretty). But life is not shaped like a story; it’s an elongate and flattened bell curve, with an attenuated, anticlimactic decline as long as its beginning. Friends have described seeing their parents lose their faculties one by one, in more or less the reverse order that their young children are acquiring them.
Another illusion we can’t seem to relinquish, partly because large and moneyed industries thrive on sustaining it, is that with enough money and information we’ll be able to control how we age and die. But one of the main aspects of aging is the loss of control. Even people with the money to arrange to age in comfort can die in agony and indignity, gabbling like infants, forgetting their own children, sans everything. Death is a lot like birth (which people also gird themselves for with books and courses and experts) — everyone’s is different, some are relatively quick and painless and some are prolonged and traumatic, but they’re all pretty messy and unpleasant and there’s not a lot you can do to prepare yourself.
I’m not trying to romanticize the beauty of osteoporosis, the wisdom of Alzheimer’s or the dignity of incontinence. More than one old person has ordered me, “Do not get old.” They did not appear to be kidding. I’m not talking about Learning from the Invaluable Life Experience of Our Elders, or even suggesting we need to accept the inevitable with grace. I am all for raging against the dying of the light, and if they ever develop DNA rejuvenation or some other longevity technique I will personally claw, throttle and gouge my way through Warren Buffett, Rupert Murdoch and any number of other decrepit billionaires in order to be first in line.
But we don’t have a choice. You are older at this moment than you’ve ever been before, and it’s the youngest you’re ever going to get. The mortality rate is holding at a scandalous 100 percent. Pretending death can be indefinitely evaded with hot yoga or a gluten-free diet or antioxidants or just by refusing to look is craven denial. “Facing it, always facing it, that’s the way to get through,” Conrad wrote in “Typhoon.” “Face it.” He was talking about more than storms. The sheltered prince Siddartha Gautama was supposedly set on the path to becoming the Buddha when he was out riding and happened to see an old man, a sick man and a dead man. Today he’d be spared the discomfiture, and the enlightenment, unless he were riding mass transit.
Just yesterday my mother sent me a poem she first read in college — Langston Hughes’s “Mother to Son.” She said she could still remember where she was, in her dorm room at Goshen College, when she came across it in her American Lit book. The title notwithstanding, it does not make for Hallmark-card copy. Life for me ain’t been no crystal stair. It tells us that this life is not a story or an adventure or a journey of spiritual self-discovery; it’s a slog. And it orders us to keep going, don’t you dare give up, no matter what. Because I’m your mother, that’s why.

Abstract
This review summarizes some of the recent findings concerning the long-held tenet that the enzyme, N-acetyltransferase, which is involved in the production of N-acetylserotonin, the immediate precursor of melatonin, may in fact not always control the quantity of melatonin generated. New evidence from several different laboratories indicates that hydroxyindole-O-methyltransferase, which O-methylates N-acetylserotonin to melatonin may be rate-limiting in some cases. Also, the review makes the point that melatonin's actions are uncommonly widespread in organs due to the fact that it works via membrane receptors, nuclear receptors/binding sites and receptor-independent mechanisms, i.e., the direct scavenging of free radicals. Finally, the review briefly summarizes the actions of melatonin and its metabolites in the detoxification of oxygen and nitrogen-based free radicals and related non-radical products. Via these multiple processes, melatonin is capable of influencing the metabolism of every cell in the organism.

Abstract
This brief review summarizes new findings related to the reported beneficial effects of melatonin on reproductive physiology beyond its now well-known role in determining the sexual status in both long-day and short-day seasonally breeding mammals. Of particular note are those reproductive processes that have been shown to benefit from the ability of melatonin to function in the reduction of oxidative stress. In the few species that have been tested, brightly colored secondary sexual characteristics that serve as a sexual attractant reportedly are enhanced by melatonin administration. This is of potential importance inasmuch as the brightness of ornamental pigmentation is also associated with animals that are of the highest genetic quality. Free radical damage is commonplace during pregnancy and has negative effects on the mother, placenta, and fetus. Because of its ability to readily pass through the placenta, melatonin easily protects the fetus from oxidative damage, as well as the maternal tissues and placenta. Examples of conditions in which oxidative and nitrosative stress can be extensive during pregnancy include preeclampsia and damage resulting from anoxia or hypoxia that is followed by reflow of oxygenated blood into the tissue. Given the uncommonly low toxicity of melatonin, clinical trials are warranted to document the protection by melatonin against pathophysiological states of the reproductive system in which free radical damage is known to occur. Finally, the beneficial effects of melatonin in improving the outcomes of in vitro fertilization and embryo transfer should be further tested and exploited. The information in this article has applicability to human and veterinary medicine.

Abstract
Melatonin, or N-acetyl-5-methoxytryptamine, is a compound derived from tryptophan that is found in all organisms from unicells to vertebrates. This indoleamine may act as a protective agent in disease conditions such as Parkinson's, Alzheimer's, aging, sepsis and other disorders including ischemia/reperfusion. In addition, melatonin has been proposed as a drug for the treatment of cancer. These disorders have in common a dysfunction of the apoptotic program. Thus, while defects which reduce apoptotic processes can exaggerate cancer, neurodegenerative disorders and ischemic conditions are made worse by enhanced apoptosis. The mechanism by which melatonin controls cell death is not entirely known. Recently, mitochondria, which are implicated in the intrinsic pathway of apoptosis, have been identified as a target for melatonin actions. It is known that melatonin scavenges oxygen and nitrogen-based reactants generated in mitochondria. This limits the loss of the intramitochondrial glutathione and lowers mitochondrial protein damage, improving electron transport chain (ETC) activity and reducing mtDNA damage. Melatonin also increases the activity of the complex I and complex IV of the ETC, thereby improving mitochondrial respiration and increasing ATP synthesis under normal and stressful conditions. These effects reflect the ability of melatonin to reduce the harmful reduction in the mitochondrial membrane potential that may trigger mitochondrial transition pore (MTP) opening and the apoptotic cascade. In addition, a reported direct action of melatonin in the control of currents through the MTP opens a new perspective in the understanding of the regulation of apoptotic cell death by the indoleamine.

Abstract
BACKGROUND: Pain relief during labour is a topic of major interest in the Netherlands. Epidural analgesia is considered to be the most effective method of pain relief and recommended as first choice. However its uptake by pregnant women is limited compared to other western countries, partly as a result of non-availability due to logistic problems. Remifentanil, a synthetic opioid, is very suitable for patient controlled analgesia. Recent studies show that epidural analgesia is superior to remifentanil patient controlled analgesia in terms of pain intensity score; however there was no difference in satisfaction with pain relief between both treatments. METHODS/DESIGN: The proposed study is a multicentre randomized controlled study that assesses the cost-effectiveness of remifentanil patient controlled analgesia compared to epidural analgesia. We hypothesize that remifentanil patient controlled analgesia is as effective in improving pain appreciation scores as epidural analgesia, with lower costs and easier achievement of 24 hours availability of pain relief for women in labour and efficient pain relief for those with a contraindication for epidural analgesia.Eligible women will be informed about the study and randomized before active labour has started. Women will be randomly allocated to a strategy based on epidural analgesia or on remifentanil patient controlled analgesia when they request pain relief during labour. Primary outcome is the pain appreciation score, i.e. satisfaction with pain relief.Secondary outcome parameters are costs, patient satisfaction, pain scores (pain-intensity), mode of delivery and maternal and neonatal side effects.The economic analysis will be performed from a short-term healthcare perspective. For both strategies the cost of perinatal care for mother and child, starting at the onset of labour and ending ten days after delivery, will be registered and compared. DISCUSSION: This study, considering cost effectiveness of remifentanil as first choice analgesia versus epidural analgesia, could strongly improve the care for 180.000 women, giving birth in the Netherlands yearly by giving them access to pain relief during labour, 24 hours a day.

Abstract
BACKGROUND: Remifentanil is an ultrashort-acting opioid with favorable pharmacokinetic properties that make it suitable as a labor analgesic. Although it crosses the placenta freely, it is eliminated quickly in the neonate by rapid metabolism and redistribution. We aimed to determine whether remifentanil compared with meperidine is effective in reducing pain scores in laboring parturients. Other effects on the mother, the labor process, and the neonate were also examined. METHODS: MEDLINE, CINAHL, Embase, Cochrane CENTRAL, and Maternity and Infant Care databases were searched without language restriction using multiple keywords for labor analgesia, remifentanil, and meperidine. Published abstracts from 5 key research meetings and references from retrieved articles were examined for additional studies. Randomized controlled trials in laboring parturients comparing remifentanil with meperidine were selected. Risk of bias was assessed using criteria outlined in the Cochrane Handbook for Systematic Reviews of Interventions. We assessed for adequacy of sequence generation, allocation concealment, blinding, and completeness of follow-up. Data were extracted from each study using a standardized data collection form. The primary outcome was reduction in pain scores (visual analog scale [VAS], 0-100 mm). We also evaluated maternal side effects (sedation, oxygen desaturation, and bradypnea) and effects on the neonate (Apgar scores, umbilical cord pH, and Neurologic and Adaptive Capacity Scores). RESULTS: Seven studies (349 patients) were identified for inclusion; only 3 studies were suitable for quantitative synthesis in a meta-analysis (233 patients). We found that remifentanil reduces the mean VAS score at 1 hour by 25 mm more than meperidine (P < 0.001) (95% confidence interval = 19-31 mm). Limited conclusions can be made regarding the side-effect profile of remifentanil because of insufficient data. CONCLUSION: Compared with meperidine, remifentanil is superior in reducing mean VAS scores for labor pain after 1 hour.

We hypothesize that remifentanil patient controlled analgesia is as effective in improving pain appreciation scores as epidural analgesia, with lower costs and easier achievement of 24 hours availability of pain relief for women in labour and efficient pain relief for those with a contraindication for epidural analgesia.Eligible women will be informed about the study and randomized before active labour has started. Women will be randomly allocated to a strategy based on epidural analgesia or on remifentanil patient controlled analgesia when they request pain relief during labour. Primary outcome is the pain appreciation score, i.e. satisfaction with pain relief.Secondary outcome parameters are costs, patient satisfaction, pain scores (pain-intensity), mode of delivery and maternal and neonatal side effects.The economic analysis will be performed from a short-term healthcare perspective. For both strategies the cost of perinatal care for mother and child, starting at the onset of labour and ending ten days after delivery, will be registered and compared. DISCUSSION: This study, considering cost effectiveness of remifentanil as first choice analgesia versus epidural analgesia, could strongly improve the care for 180.000 women, giving birth in the Netherlands yearly by giving them access to pain relief during labour, 24 hours a day.

Abstract
BACKGROUND: Remifentanil is an ultrashort-acting opioid with favorable pharmacokinetic properties that make it suitable as a labor analgesic. Although it crosses the placenta freely, it is eliminated quickly in the neonate by rapid metabolism and redistribution. We aimed to determine whether remifentanil compared with meperidine is effective in reducing pain scores in laboring parturients. Other effects on the mother, the labor process, and the neonate were also examined. METHODS: MEDLINE, CINAHL, Embase, Cochrane CENTRAL, and Maternity and Infant Care databases were searched without language restriction using multiple keywords for labor analgesia, remifentanil, and meperidine. Published abstracts from 5 key research meetings and references from retrieved articles were examined for additional studies. Randomized controlled trials in laboring parturients comparing remifentanil with meperidine were selected. Risk of bias was assessed using criteria outlined in the Cochrane Handbook for Systematic Reviews of Interventions. We assessed for adequacy of sequence generation, allocation concealment, blinding, and completeness of follow-up. Data were extracted from each study using a standardized data collection form. The primary outcome was reduction in pain scores (visual analog scale [VAS], 0-100 mm). We also evaluated maternal side effects (sedation, oxygen desaturation, and bradypnea) and effects on the neonate (Apgar scores, umbilical cord pH, and Neurologic and Adaptive Capacity Scores). RESULTS: Seven studies (349 patients) were identified for inclusion; only 3 studies were suitable for quantitative synthesis in a meta-analysis (233 patients). We found that remifentanil reduces the mean VAS score at 1 hour by 25 mm more than meperidine (P < 0.001) (95% confidence interval = 19-31 mm). Limited conclusions can be made regarding the side-effect profile of remifentanil because of insufficient data. CONCLUSION: Compared with meperidine, remifentanil is superior in reducing mean VAS scores for labor pain after 1 hour.

Abstract
BACKGROUND: An organizational approach is proposed as an immediate solution for improving postoperative pain (POP) management. The aim was to evaluate the clinical effectiveness of a quality management system (QMS), based on procedure-specific, multimodal analgesic protocols, modified to meet the individual patients' requirements. METHODS: Patients from the orthopaedic, gynaecological, visceral, and trauma surgery departments of the university hospital were involved in two prospective surveys. Survey 1 was performed at baseline and survey 2 was performed after the implementation of QMS within an interval of 1 year. The patients were asked to report pain intensity on the visual rating scale, incidence of analgesia-related side-effects, and incidence of pain interference with the items of life quality and their satisfaction with the treatment of POP. RESULTS: Patients from Survey 2 (n=251) reported 25-30% less pain than those from Survey 1 (n=269) (P<0.0001). Nausea was reported by 40% of the patients from Survey 1 vs 17% from Survey 2, vomiting by 25 vs 11% and fatigue by 76% in Survey 1 vs 30% in Survey 2 (P<0.0001). Life quality and patients' satisfaction improved in Survey 2 vs Survey 1 (P<0.001). CONCLUSIONS: The implementation of QMS allowed the reduction in POP intensity with a simultaneous decrease in analgesia-related side-effects. This has led to an increased quality of life and patient satisfaction.
