Ketamina en analgesia postoperatoria

La ketamina (compuesto CI-581) es un derivado la fenciclidina, formulado como mezcla racémica donde los dos estereoisómeros tienen diferente potencia anestésica-analgésica, pero cinética similar. Es una droga fantástica que fue introducida en anestesia por Corssen en 1966. Posee efectos anestésicos, sedantes, amnésicos, neuroprotectivos, analgésicos y recreacionales. Este fármaco ha sido redescubierto en forma reciente cuando se conocieron sus interacciones con el receptor NMDA y ahora se utiliza por diversas vías (iv, im, oral, bucal, rectal, neuroaxial, nasal), no solo en anestesia, sino en dolor agudo y en dolor crónico oncológico y no oncológico


Ketamine (compound CI-581) is a phencyclidine derivative, formulated as a racemic mixture where the two stereoisomers have different anesthetic-analgesic potency, but similar kinetics. It's a great drug that was introduced in 1966 by Corssen in clinical anesthesia. It has anesthetic, sedative, amnesic, neuroprotective, analgesic and recreational effects. This drug has been rediscovered recently due to its interactions with the NMDA receptor and is now used by various routes (iv, im, oral, buccal, rectal, neuraxial, nasal), not only in anesthesia, but also in post operative pain, chronic cancer pain and noncancer chronic pain.

Abstract
BACKGROUND: In this study, we assessed the effectiveness of ketamine as an alternative to non-steroidal anti-inflammatory drugs (NSAID), to manage acute postoperative pain after spinal fusion when given intravenously via a patient-controlled analgesia (PCA) pump in which the dose was proportional to that of fentanyl. METHODS: Forty patients undergoing 1-2 level spinal fusion were enrolled in this study. Patients were intraoperatively randomized into two groups to receive intravenous PCA consisting either of fentanyl 0.4 µg/ml/kg (control group) or fentanyl 0.4 µg/ml/kg with ketamine 30 µg/ml/kg (ketamine group) after intravenous injection of a loading dose. The loading dose in the control group was fentanyl 1 µg/kg with normal saline equal to ketamine volume and in the ketamine group it was fentanyl 1 µg/kg with ketamine 0.2 mg/kg. The verbal numerical rating scale (NRS), fentanyl and ketamine infusion rate, and side effects were evaluated at 1, 24, and 48 hours after surgery. RESULTS: There were no significant differences in patient demographics, duration of surgery and anesthesia or intra-operative opioids administration. We did not find any significant differences in the mean infusion rate of intraoperative remifentanil or postoperative fentanyl or in the side effects between the groups, but we did find a significant difference in the NRS between the groups. CONCLUSIONS: Based on our results, we conclude that a small dose of ketamine (0.5-2.5 µg/kg/min) proportional to fentanyl is not only safe, but also lowers postoperative pain intensity in patients undergoing spinal fusion, although the opioid-sparing effects of ketamine were not demonstrated.

Abstract
OBJECTIVES: There is a little data about rectal administration of Ketamine as a postoperative analgesic, so we compared the efficacy of rectal ketamine with rectal acetaminophen, which is applied routinely for analgesia after painful surgeries like tonsillectomy.METHODS: In this single-blinded comparative trial, we enrolled 70 children undergoing elective tonsillectomy, and divided them randomly in two groups. Patients received rectal ketamine (2 mg / kg) or rectal acetaminophen (20 mg / kg) at the end of surgery. The children's Hospital of Eastern Ontario Pain scale was used to estimate pain in children. Also the vital signs, Wilson sedation scale, and side effects in each group were noted and compared for 24 hours. RESULTS: The ketamine group had a lower pain score at 15 minutes and 60 minutes after surgery in Recovery (6.4 ± 0.8, 7.4 ± 1 vs. 7.1 ± 1.2, 7.8 ± 1.2 in the acetaminophen group, P < 0.05) and one hour and two hours in the ward (7.2 ± 0.7, 7 ± 0.5 vs. 7.9 ± 1.2, 7.5 ± 1.2 in the acetaminophen group, P < 0.05), with no significant differences till 24 hours. Dreams and hallucinations were not reported in the ketamine group. Systolic blood pressure was seen to be higher in the ketamine group (104.4 ± 7.9 vs. 99.8 ± 7.7 in the acetaminophen group) and nystagmus was reported only in the ketamine group (14.2%). Other side effects were equivalent in both the groups. CONCLUSIONS: With low complications, rectal ketamine has analgesic effects, especially in the first hours after surgery in comparison with acetaminophen, and it can be an alternative analgesic with easy administration in children after tonsillectomy.

Abstract
AIM: To assess the effect of peritonsillar infiltration of ketamine and tramadol on post tonsillectomy pain and compare the side effects. METHODS: The double-blind randomized clinical trial was performed on 126 patients aged 5-12 years who had been scheduled for elective tonsillectomy. The patients were randomly divided into 3 groups to receive either ketamine, tramadol, or placebo. They had American Society of Anesthesiologists physical status class I and II. All patients underwent the same method of anesthesia and surgical procedure. The three groups did not differ according to their age, sex, and duration of anesthesia and surgery. Post operative pain was evaluated using CHEOPS score. Other parameters such as the time to the first request for analgesic, hemodynamic elements, sedation score, nausea, vomiting, and hallucination were also assessed during 12 hours after surgery. RESULTS: Tramadol group had significantly lower pain scores (P=0.005), significantly longer time to the first request for analgesic (P=0.001), significantly shorter time to the beginning of liquid regimen (P=0.001), and lower hemodynamic parameters such as blood pressure (P=0.001) and heart rate (P=0.001) than other two groups. Ketamine group had significantly greater presence of hallucinations and negative behavior than tramadol and placebo groups. The groups did not differ significantly in the presence of nausea and vomiting. CONCLUSION: Preoperative peritonsillar infiltration of tramadol can decrease post-tonsillectomy pain, analgesic consumption, and the time to recovery without significant side effects.

Health Situation in the Americas . Basic Indicators 2012

Health Situation in the Americas . Basic Indicators 2012


Pan American Health Organization/World Health Organization (PAHO/WHO) - 2012

presents the latest available information on health indicators for 48 countries/territories in the Region of the Americas.


Available online at: http://bit.ly/NxsA7Q


“…..This edition highlights the mortality due to external causes (EC); those causes of death different from natural causes and recognized as avoidable such as suicides, homicides and accidents. From the data reported by the countries, it is estimated that over 5.5 million people died from EC in the Region between 1999 and 2009.

Three and a half million deaths (64%) occurred among the young and adult population (10-49 years old) with an average of 319,000 deaths per year; 84% of the deaths happened among males, five times more deaths among men than women. The most frequent causes were homicides (33%) and land transport accidents (26%).


Mortality from land transport accidents and homicides might be associated with economic, educational, political, social, and cultural factors. Also, they overburden the health care systems and pose a high cost on society, in addition to the suffering of the victims and their families6. In several countries of the Region the proportion of population in productive ages regarding the number of the youngest and the oldest are increasing, favoring their economic growth.


The negative potential impact of these deaths over this “demographic bonus” is an important call to countries for action given the preventability of these outcomes.

The information presented in this brochure has been compiled, processed and reviewed by PAHO/WHO technical staff in collaboration with ministries of health and national statistics offices from countries of the Americas ….”

Abstract
BACKGROUND: Nuss surgery is preferred in pectus excavatum repair because this procedure produces excellent cosmetic results and prevents postoperative distressed pulmonary function. However, the procedure causes severe pain due to thoracic expansion. This study was designed to investigate the analgesic effect of small doses of ketamine on an intravenous patient-controlled analgesia (IV-PCA) using hydromorphone and ketorolac for pain control after Nuss surgery. METHODS: Forty-four patients undergoing elective Nuss surgery were randomly assigned to receive hydromorphone 3 µg/kg/hr, ketorolac 0.05 mg/kg/hr and ondansetron 0.1 mg/kg/day (Group HO, n = 22) or hydromorphone 3 µg/kg/hr, ketorolac 0.05 mg/kg/hr, ondansetron 0.1 mg/kg/day and ketamine 0.15 mg/kg/hr (Group HK, n = 22) via an IV-PCA pump after surgery. A blind observer evaluated each patient using the Modified Children's Hospital of Eastern Ontario Pain Scale (CHEOPS) for the assessment of pain control. The total administered PCA volume, side effects and parents satisfaction with pain control were assessed at postoperative 1, 4, 8, 12, 24, and 48 hours. RESULTS: There were no significant differences in Modified CHEOPS between the groups during postoperative 48 hours. The total PCA volume in group HK was significantly lower than that in group HO (P < 0.05). The side effects in both groups did not significantly differ except for pruritus. The levels of satisfaction from the parents were not significantly different between the groups. CONCLUSIONS: A small dose of ketamine on IV-PCA reduced the total administered dose of IV-PCA with hydromorphone and ketorolac and reduced the incidence of pruritus after the Nuss procedure in pediatric patients.

Abstract
Ketamine, a noncompetitive N-methyl-d-aspartate antagonist, provides analgesia and prevents chronic pain following thoracotomy. The study was aimed to assess the effect of intravenous low-dose ketamine on continuous intercostal nerve block analgesia following thoracotomy. The study was a prospective, randomized, double-blinded, and placebo-controlled clinical study, performed in a single university hospital. Sixty patients, undergoing elective lobectomy through an open posterolateral thoracotomy, were included. For postoperative pain, all patients received a continuous intercostal nerve block with bupivacaine plus intravenous paracetamol and ketoprofen. In addition, patients were randomized to have intravenous ketamine (0.1 mg/kg as a preincisional bolus followed by a continuous infusion of 0.05 mg/kg/h) in group 1 or intravenous placebo in group 2. Patients reporting a visual analog scale pain score at rest ≥40 mm received intravenous morphine sulfate as rescue analgesia. The following parameters were assessed every 6 hours for 3 postoperative days: Visual analog scale pain scores at rest and during coughing, requirement of rescue analgesia with morphine, Ramsay sedation scores and psychomimetic adverse effects. Both the groups were statistically comparable regarding visual analog scale pain scores at rest (P=0.75) and during coughing (P=0.70), number of morphine deliveries (P=0.17), cumulative dose of rescue morphine (P=0.2), sedation scores (P=0.4), and psychomimetic adverse effects (P=0.09). Intravenous low-dose ketamine, when combined with continuous intercostal nerve block, did not decrease acute pain scores and supplemental morphine consumption following thoracotomy.

Abstract
PURPOSE: The aim of this prospective, double-blind, randomized study was to investigate the analgesic effects of low-dose ketamine on intravenous patient-controlled analgesia (IV-PCA) with fentanyl for pain control in pediatric patients following the Nuss procedure for pectus excavatum. MATERIALS AND METHODS: Sixty pediatric patients undergoing the Nuss procedure were randomly assigned to receive fentanyl (Group F, n=30) or fentanyl plus ketamine (Group FK, n=30). Ten minutes before the end of surgery, following the loading dose of each solution, 0.5 μg/kg/hr of fentanyl or 0.5 μg/kg/hr of fentanyl plus 0.15 mg/kg/hr of ketamine was infused via an IV-PCA pump (basal rate, 1 mL/hr; bolus, 0.5 mL; lock out interval, 30 min). Fentanyl consumption, pain score, ketorolac use, nausea/vomiting, ondansetron use, pruritus, respiratory depression, hallucination, dreaming, and parent satisfaction with pain control were measured throughout the 48 hours following surgery. RESULTS: The pain scores, ketorolac use, and fentanyl consumption of Group FK were significantly lower than in Group F (p<0.05). The incidence of nausea/vomiting and ondansetron use in Group FK was significantly lower than in Group F (p<0.05). There were no reports of respiratory depression, hallucination or dreaming. Parent satisfaction with pain control was similar between the two groups. CONCLUSION: We concluded that low-dose ketamine added to IV-PCA with fentanyl after the Nuss procedure in pediatric patients can reduce pain scores, consumption of fentanyl, and incidence of nausea/vomiting without increasing side effects.

Abstract
Peri-operative anaphylaxis is an important cause for mortality and morbidity associated with anaesthesia. The true incidence is unknown and is most likely under reported. Diagnosis can be difficult, particularly as a number of drugs are given simultaneously and any of these agents can potentially cause anaphylaxis. This review covers the clinical features, differential diagnosis and management of anaphylaxis associated with anaesthesia. The investigations to confirm the clinical suspicion of anaphylaxis and further tests to identify the likely drug(s) are examined. Finally the salient features of common and rare causes including non-drug substances are described.

Jets Lose Revis to Torn Knee Ligament

Jets Lose Revis to Torn Knee Ligament

Rhona Wise/Associated Press
After missing this previous week's game because of a concussion, Darrelle Revis suffered a knee injury against the Dolphins and is expected to have surgery in the coming weeks.


FLORHAM PARK, N.J. — After uttering the words he hoped he would not have to say, Rex Ryan looked down at the lectern and away from the cameras. A second went by. Then two. Then three, as if by taking time to collect his thoughts Ryan would somehow reverse the harsh sentence rendered Monday, when tests confirmed that the All-Pro cornerback Darrelle Revis had torn the anterior cruciate ligament in his left knee and would require surgery, ending his season after three games.

Kyle Wilson, who will start in place of Darrelle Revis, was called for interference against the Dolphins’ Davone Bess on this play.
“I don’t know what else to say about it,” Ryan said.
Ryan just stood there, his face ashen, but the words eventually flowed from the coach’s mouth like a lazy river. He spoke of resilience and teamwork and adversity, how he and his coaching staff accepted Revis’s injury as “a personal challenge” to revitalize a team that had lost its best and most indispensable player. But Ryan did not address, at least not directly, that murky area between popular perception and harsh reality — that Revis’s absence deals the 2-1 Jets a potentially devastating blow, weakening not only their defense but also their playoff hopes.
“I have all the respect in the world for Tom Brady and Aaron Rodgers and Peyton Manning, but Darrelle’s the best player in the league,” said the former San Francisco cornerback Eric Davis, an analyst on NFL Network. “No other player goes out with those expectations on him every single week and produces like he does. No one has a tougher assignment week in, week out than Revis. Brady and Rodgers and Manning throw interceptions. Revis doesn’t make mistakes.”
He didn’t, at least, before his knee buckled while he made a cut in the third quarter of the Jets’ 23-20 overtime victory against Miami on Sunday. Their aggressive defense relies heavily on Revis, a neutralizing force in one-on-one coverage; according to the statistical Web siteProFootballFocus.com, which last season rated him as the best cornerback in the N.F.L., receivers caught only a league-low 41.2 percent of passes thrown while Revis was covering them.
By erasing the opposition’s top receiving threat, effectively eliminating a huge swath of the field, Revis allows Ryan to deploy the other 10 defenders in exotic ways — in creative blitz packages, in bracket coverage and in space, prowling other areas of the field.
“All that changes dramatically moving forward,” said Brian Billick, the former Ravens coach who works as an analyst for Fox Sports and NFL Network.
In the coming weeks, some of the N.F.L.’s most dangerous receivers — including Larry Fitzgerald, Andre Johnson and Reggie Wayne — visit MetLife Stadium, where Revis would surely have shadowed them. Instead, that burden falls to Antonio Cromartie — or, more likely, to his fellow defensive backs and him because the Jets are unlikely to trust Cromartie the same way they did Revis. With Revis sidelined, opponents are almost certain to emphasize their No. 1 receivers, devising game plans that funnel passes toward them.
Tom Moore, the former Indianapolis offensive coordinator who worked as a consultant last season for the Jets, said he always took Revis into account when calling plays, telling his players to “play smart, not scared.” In the Jets’ 2011 playoff victory against the Colts, Revis held Wayne to one reception for a single yard. The details have faded for Moore, but he said of Revis, “You always knew he was there.”
To compensate, Billick said the Jets could start playing more zone coverage, which would alleviate the pressure on Cromartie and Kyle Wilson, elevated from nickel corner to starter in Revis’s absence. When injuries diluted the Ravens’ secondary heading into a 2007 game in Seattle, Ryan, reluctantly, kept the defensive backs in a two-deep zone for much of the game, Billick said, “even though it killed him.”
“To do anything else would have been a mistake,” said Billick, who was Ryan’s boss in Baltimore for nine seasons. “He’s not in that dire straits now, because he has good people behind Revis. Rex’s nature is always to bring pressure — that’s his answer to everything. But you might be a little bit more tentative about bringing five- or six- or seven-man pressure knowing that your back end’s going to be more vulnerable.”
Ryan disagreed. Instead of taking a more conservative approach, as many would probably expect, Ryan said he might be more aggressive, mentioning how his father, Buddy, coached teams in Chicago that harassed quarterbacks despite an anonymous secondary.
In theory, that strategy makes sense: if the Jets feel exposed at cornerback, increasing their pressure would be a way of preventing the quarterback from dissecting the diminished secondary. In practice, the counterargument is fierce; the Jets, supported by three weeks of evidence, have struggled at generating a consistent pass rush, recording 3 sacks and 10 quarterback hits — 5 across their last two games.
“We’ve got to get 1,000 times better,” said linebacker Calvin Pace, who lamented the Jets’ inability to stop the run (148.7 yards a game) and generosity in third-down situations, yielding a 55.8 percent conversion rate. “It’s hard to rush the passer when you get third-and-4. The offense can pretty much do what they want.”
Ryan said: “Maybe we play some opponents differently. There’s different ways to skin a cat. You can’t just take away their best receiver with one guy. Again, we’ll find a way.”
