Hace 2000 días/Two thousand days ago

Hace 2000 dias.
Hace 2000 días, el primero de Enero 2010, iniciamos este Programa Educativo Alfa como un proyecto dedicado a enviar cada día artículos en PDF o en HTML a un reducido grupo de colegas anestesiólogos, intensivistas, cirujanos, internistas, algólogos y especialidades relacionadas, incluyendo enfermeras y estudiantes de medicina. El proyecto inicial se ha convertido en un programa educativo exitoso que llega a 4500 miembros en los cinco continentes, muy en especial a los países de Latinoamérica. Se han enviado 7,540 artículos, 45 libros, varias revistas completas, y videoclips. Además se han promovido cursos, eventos, congresos y enlaces de interés académico. Al principio teníamos dudas sobre su utilidad, pero al paso de los primeros meses vimos con agrado la buena aceptación y crecimiento lento y paulatino del número de subscritores, con un bajo porcentaje de cancelaciones. Hoy en día no solo se envían artículos completos, sino que hemos agregado enlaces a revistas, a libros, videos y recién creamos el correo con la Imagen del Mes, donde se incluyen fotografías clínicas originales adicionadas de información médica disponible en la WEB.
Al paso de estos 2000 días hemos aprendido a seleccionar la información enviada, a escuchar las sugerencias recibidas, a responder las consultas de colegas y pacientes con prontitud, al igual que hemos ido presentando y publicando nuestra propia experiencia en diversos foros y revistas biomédicas. La meta fundamental de nuestro portal www.anestesia-dolor.org es facilitar la educación médica continuada utilizando la información gratuita y selecta disponible en la WEB.
Agradecemos el dejarnos llegar con este programa hasta su ordenador, y se le invita a seguir con nosotros, y a difundir este programa educativo entre sus colegas. Si desea hacer un donativo económico que nos ayude a mejorar este programa le estaremos muy agradecidos.
Aprovechamos la coincidencia de fechas para FELICITAR a todos los colegas que además de llevar en hombros su responsabilidad profesional, hoy celebran el DIA de los PADRES! 

 
2000 days ago, January first 2010, we initiated this Educational Alfa Program as a project dedicated to daily post articles in PDF or HTML to a small group of colleagues anesthesiologists, intensivists, surgeons, internists, pain medicine, and related specialties, including nurses and medical students. The initial project has become a successful educational program that reaches 4,500 members on five continents, most in Latin America countries. We have sent 7,540 articles, 45 books, several full magazines, and video clips. We have also promoted courses, events, conferences and links with academic interest. We initially had doubts about its usefulness, but over the first few months we saw with pleasure the good acceptance and slow and gradual growth in the number of subscribers, with a very low percentage of cancellations. Besides all this, we've added links to journals, books, videos and newly created the Image of the Month, where original clinical photographs and medical information are included.
In these 2000 days we have learned to select the information to be sent, listen to suggestions received, and answer queries from colleagues and patients promptly. We also have been presenting and publishing our own experience in various forums and biomedical journals. The primary goal of our website www.anestesia-dolor.org is to facilitate continuing medical education using select information available free on the Web.
We appreciate letting us get this program to your computer, invite you to follow us, and ask you to spread this education program among your colleagues. If you want to make a financial donation to help us to improve this program we would be very grateful.
We take this coincidence of dates to congratulate all colleagues that in addition to carrying on their shoulders their professional responsibility, today celebrate Father's Day!

Anesthesiology. 2014 Aug;121(2):219-31. doi: 10.1097/ALN.0000000000000334.
Abstract
BACKGROUND: No externally validated risk score for postoperative pulmonary complications (PPCs) is currently available. The authors tested the generalizability of the Assess Respiratory Risk in Surgical Patients in Catalonia risk score for PPCs in a large European cohort (ProspectiveEvaluation of a RIsk Score for postoperative pulmonary COmPlications in Europe). METHODS: Sixty-three centers recruited 5,859 surgical patients receiving general, neuraxial, or plexus block anesthesia. The Assess RespiratoryRisk in Surgical Patients in Catalonia factors (age, preoperative arterial oxygen saturation in air, acute respiratory infection during the previous month, preoperative anemia, upper abdominal or intrathoracic surgery, surgical duration, and emergency surgery) were recorded, along with PPC occurrence (respiratory infection or failure, bronchospasm, atelectasis, pleural effusion, pneumothorax, or aspiration pneumonitis). Discrimination, calibration, and diagnostic accuracy measures of the Assess Respiratory Risk in Surgical Patients in Catalonia score's performance were calculated for the Prospective Evaluation of a RIsk Score for postoperative pulmonary COmPlications in Europe cohort and three subsamples: Spain, Western Europe, and Eastern Europe. RESULTS: The full Prospective Evaluation of a RIsk Score for postoperative pulmonary COmPlications in Europe data set included 5,099 patients; 725 PPCs were recorded for 404 patients (7.9%). The score's discrimination was good: c-statistic (95% CI), 0.80 (0.78 to 0.82). Predicted versus observed PPC rates for low, intermediate, and high risk were 0.87 and 3.39% (score <26), 7.82 and 12.98% (≥ 26 and <45), and 38.13 and 38.01% (≥ 45), respectively; the positive likelihood ratio for a score of 45 or greater was 7.12 (5.93 to 8.56). The score performed best in the Western Europe subsample-c-statistic, 0.87 (0.83 to 0.90) and positive likelihood ratio, 11.56 (8.63 to 15.47)-and worst in the Eastern Europe subsample. The predicted (5.5%) and observed (5.7%) PPC rates were most similar in the Spain subsample. CONCLUSIONS: The Assess Respiratory Risk in Surgical Patients in Catalonia score predicts three levels of PPC risk in hospitals outside thedevelopment setting. Performance differs between geographic areas.

Abstract
BACKGROUND: Postoperative respiratory failure (PRF) (requiring mechanical ventilation > 48 h after surgery or unplanned intubation within 30 days of surgery) is associated with significant morbidity and mortality. The objective of this study was to identify preoperative factors associated with an increased risk of PRF and subsequently develop and validate a risk calculator. METHODS: The American College of Surgeons National Surgical Quality Improvement Program (NSQIP), a multicenter, prospective data set (2007-2008), was used. The 2007 data set (n = 211,410) served as the training set and the 2008 data set (n = 257,385) as the validation set. RESULTS: In the training set, 6,531 patients (3.1%) developed PRF. Patients who developed PRF had a significantly higher 30-day mortality (25.62% vs 0.98%, P < .0001). On multivariate logistic regression analysis, five preoperative predictors of PRF were identified: type of surgery, emergency case, dependent functional status, preoperative sepsis, and higher American Society of Anesthesiologists (ASA) class. The risk model based on the training data set was subsequently validated on the validation data set. The model performance was very similar between the training and the validation data sets (c-statistic, 0.894 and 0.897, respectively). The high c-statistics (area under the receiver operating characteristic curve) indicate excellent predictive performance. The risk model was used to develop an interactive risk calculator. CONCLUSIONS: Preoperative variables associated with increased risk of PRF include type of surgery, emergency case, dependent functional status, sepsis, and higher ASA class. The validated risk calculator provides a risk estimate of PRF and is anticipated to aid in surgical decision making and informed patient consent.

CPPD/PDPH / Cefalea postpunción dural

Cefalea postpunción dural
Post-dural puncture headache.
Ghaleb A, Khorasani A, Mangar D.
Int J Gen Med. 2012;5:45-51. doi: 10.2147/IJGM.S17834. Epub 2012 Jan 12.
Abstract
Since August Bier reported the first case in 1898, post-dural puncture headache (PDPH) has been a problem for patients following dural puncture. Clinical and laboratory research over the last 30 years has shown that use of smaller-gauge needles, particularly of the pencil-point design, are associated with a lower risk of PDPH than traditional cutting point needle tips (Quincke-point needle). A careful history can rule out other causes of headache. A postural component of headache is the sine qua non of PDPH. In high-risk patients < 50 years, post-partum, in the event a large-gauge needle puncture is initiated, an epidural blood patch should be performed within 24-48 hours of dural puncture. The optimum volume of blood has been shown to be 12-20 mL for adult patients. Complications caused by autologous epidural blood patching (AEBP) are rare.

Medicamentos para prevenir la cefalea postpunción dural
Drug therapy for preventing post-dural puncture headache.
Basurto Ona X1, Uriona Tuma SM, Martínez García L, Solà I, Bonfill Cosp X.
Cochrane Database Syst Rev. 2013 Feb 28;2:CD001792. doi: 10.1002/14651858.CD001792.pub3.
Abstract
BACKGROUND: Post-dural (post-lumbar or post-spinal) puncture headache (PDPH) is one of the most common complications of diagnostic, therapeutic or inadvertent lumbar punctures. Many drug options have been used to prevent headache in clinical practice and have also been tested in some clinical studies, but there are still some uncertainties about their clinical effectiveness. OBJECTIVES: To assess the effectiveness and safety of drugs for preventing PDPH in adults and children. SEARCH METHODS: The search strategy included the Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library 2012, Issue 5), MEDLINE (from 1950 to May 2012), EMBASE (from 1980 to May 2012) and CINAHL (from 1982 to June 2012). There was no language restriction. SELECTION CRITERIA: We considered randomised controlled trials (RCTs) that assessed the effectiveness of any drug used for preventing PDPH. DATA COLLECTION AND ANALYSIS: Review authors independently selected studies, assessed risks of bias and extracted data. We estimated risk ratios (RR) for dichotomous data and mean differences (MD) for continuous outcomes. We calculated a 95% confidence interval (CI) for each RR and MD. We did not undertake meta-analysis because participants' characteristics or assessed doses of drugs were too different in the included studies. We performed an intention-to-treat (ITT) analysis. MAIN RESULTS: We included 10 RCTs (1611 participants) in this review with a majority of women (72%), mostly parturients (women in labour) (913), after a lumbar puncture for regional anaesthesia. Drugs assessed were epidural and spinal morphine, spinal fentanyl, oral caffeine, rectal indomethacin, intravenous cosyntropin, intravenous aminophylline and intravenous dexamethasone.All the included RCTs reported data on the primary outcome, i.e. the number of participants affected by PDPH of any severity after a lumbar puncture. Epidural morphine and intravenous cosyntropin reduced the number of participants affected by PDPH of any severity after a lumbar puncture when compared to placebo. Also, intravenous aminophylline reduced the number of participants affected by PDPH of any severity after a lumbar puncture when compared to no intervention, while intravenous dexamethasone increased it. Spinal morphine increased the number of participants affected by pruritus when compared to placebo, and epidural morphine increased the number of participants affected by nausea and vomiting when compared to placebo. Oral caffeine increased the number of participants affected by insomnia when compared to placebo.The remainder of the interventions analysed did not show any relevant effect for any of the outcomes.None of the included RCTs reported the number of days that patients stayed in hospital.
AUTHORS' CONCLUSIONS: Morphine and cosyntropin have shown effectiveness for reducing the number of participants affected by PDPH of any severity after a lumbar puncture, when compared to placebo, especially in patients with high risk of PDPH, such as obstetric patients who have had an inadvertent dural puncture. Aminophylline also reduced the number of participants affected by PDPH of any severity after a lumbar puncture when compared to no intervention in patients undergoing elective caesarean section. Dexamethasone increased the risk of PDPH, after spinal anaesthesia for caesarean section, when compared to placebo. Morphine also increased the number of participants affected by adverse events (pruritus and nausea and vomiting)There is a lack of conclusive evidence for the other drugs assessed (fentanyl, caffeine, indomethacin and dexamethasone).These conclusions should be interpreted with caution, owing to the lack of information, to allow correct appraisal of risk of bias and the small sample sizes of studies.

Abstract
INTRODUCTION: Post-dural puncture headache (PDPH) is a common complication of lumbar puncture for any purpose. To avoid the need for invasive methods of treating PDPH such as blood patch, the search for novel pharmacological agents to manage PDPH continues. The aim of this study was to compare the effects of acetaminophen, gabapentin and pregabalin in controlling PDPH in patients who underwent surgery under spinal anesthesia. MATERIALS AND METHODS: A total of 90 patients who underwent elective orthopedic surgery under spinal anesthesia and suffered from PDPH consequently were enrolled in this randomized trial. Patients were categorized randomly into three groups. Group A, B and C have received Acetaminophen, Gabapentin and Pregabalin (3 times a day for 3 days), respectively. The effect of medications on the severity of PDPH was evaluated and compared using visual analog scale (VAS). RESULTS:
The mean VAS score was significantly lower in pregabalin group compared with others 24, 48 and 72 h after the onset of headache (P = 0.001 for all of them) and lower in Gabapentin group compared with Acetaminophen group 24, 48 and 72 h after the onset of headache (P = 0.001 for all analyses). No adverse outcome was reported in groups. CONCLUSION: Pregabalin and gabapentin are both useful and safe in management of PDPH, but pregabalin is more effective in this regard.

Dexmedetomidina en geriatría/Dexmedetomidine in geriatrics

Delirio en el anciano: Uso de la dexmedetomidina
Delirium tremens in the elderly: Papel de la dexmedetomidina
Sehgal V, Bajwa SJ, Consalvo JA, Bajaj A, Sehgal R.
Int J Nutr Pharmacol Neurol Dis [serial online] 2015 [cited 2015 Jun 8];5:89-94.
Abstract
The elderly are more predisposed to depression, which puts them at high risk for alcohol abuse and alcohol-related disorders such as delirium tremens (DTs). But its clinical presentation is often complicated by underlying comorbid conditions, such as congestive heart failure (CHF), atrial fibrillation (AF), sepsis, chronic kidney disease (CKD), electrolyte imbalance, dementia, malglycemia, nutritional deficiencies, and polypharmacy. The current review is aimed at defining the appropriate management of these clinical conundrums that frequently accompany alcohol abuse in the elderly, leading to increased morbidity and mortality. It also emphasizes the emerging role of dexmedetomidine in treating the elderly with DTs.

Anestesia ambulatoria en pediatria/Pediatric ambulatory anesthesia

Anestesia intravenosa versus inhalada para cirugía pediátrica en paciente ambulatorio
Intravenous versus inhalational anaesthesia for paediatric outpatient surgery.
Ortiz AC1, Atallah AN, Matos D, da Silva EM.
Cochrane Database Syst Rev. 2014 Feb 7;2:CD009015. doi: 10.1002/14651858.CD009015.pub2.
Abstract
BACKGROUND: Ambulatory or outpatient anaesthesia is performed in patients who are discharged on the same day as their surgery. Perioperative complications such as postoperative nausea and vomiting (PONV), postoperative behavioural disturbances and cardiorespiratory complications should be minimized in ambulatory anaesthesia. The choice of anaesthetic agents and techniques can influence the occurrence of these complications and thus delay in discharge.
OBJECTIVES: The objective of this review was to evaluate the risk of complications (the risk of postoperative nausea and vomiting (PONV), admission or readmission to hospital, postoperative behavioural disturbances and perioperative respiratory and cardiovascular complications) and recovery times (time to discharge from recovery ward and time to discharge from hospital) comparing the use of intravenous toinhalational anaesthesia for paediatric outpatient surgery.
SEARCH METHODS: We searched the Cochrane Central Register of Controlled Trials (CENTRAL) in The Cochrane Library (2013, Issue 8); MEDLINE (1948 to 1 October 2013); EMBASE (1974 to 1 October 2013); Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS) (1982 to 1 October 2013). We also handsearched relevant journals and searched the reference lists of the articles identified. SELECTION CRITERIA: We included randomized controlled trials comparing paediatric outpatient surgery using intravenous versus inhalationalanaesthesia. DATA COLLECTION AND ANALYSIS: Two review authors independently assessed trial quality and extracted the data. When necessary, we requested additional information and clarification of published data from the authors of individual trials. MAIN RESULTS: We included 16 trials that involved 900 children in this review. Half of all the studies did not describe the generation of randomized sequence and most studies did not describe adequate allocation sequence concealment. The included studies showed variability in the types and combinations of drugs and the duration of anaesthesia, limiting the meta-analysis and interpretation of the results.For the induction and maintenance of anaesthesia there was a significant difference favouring intravenous anaesthesia with propofol; the incidence of PONV was 32.6% for sevoflurane and 16.1% for propofol (odds ratio (OR) 2.96; 95% confidence interval (CI) 1.35 to 6.49, four studies, 176 children, low quality evidence). The risk of postoperative behavioural disturbances also favoured intravenous anaesthesiaas the incidence was 24.7% for sevoflurane and 11.5% for propofol (OR 2.67; 95% CI 1.14 to 6.23, four studies, 176 children, very low quality evidence). There were no differences between groups in the risk of intraoperative and postoperative respiratory and cardiovascular complications (OR 0.75; 95% CI 0.27 to 2.13, three studies,130 children, very low quality evidence) and there was no difference in the time to recovery from anaesthesia and discharge from hospital. These results should be interpreted with caution due to heterogeneity between studies in the type and duration of operations, types of reported complications and the high risk of bias in almost all studies. Two studies (105 participants) compared halothane to propofol and showed heterogeneity in duration of anaesthesia and in the type of ambulatory procedure. For the risk of PONV the results of the studies were conflicting, and for the risks of intraoperative and postoperative complications there were no significant differences between the groups.For the maintenance of anaesthesia there was a significant difference favouring anaesthesia with propofol, with or without nitrous oxide (N2O), when compared to thiopentone and halothane + N2O (OR 3.23; 95% CI 1.49 to 7.02, four studies, 176 children, low quality evidence; and OR 7.44; 95% CI 2.60 to 21.26, two studies, 87 children, low quality evidence), respectively. For the time to discharge from the recovery room, there were no significant differences between groups. The studies were performed with different ambulatory surgeries and a high risk of bias.Four studies (250 participants) compared the induction of anaesthesia by theinhalational or intravenous route, with inhalational anaesthesia for maintenance, and found no significant differences between groups in all outcomes (the risk of PONV, behavioural disturbances, respiratory and cardiovascular complications and time to discharge from recovery room). Meta-analysis was not done in this comparison because of significant clinical heterogeneity.Readmission to hospital was not reported in any of the included studies. No other adverse effects were reported.
AUTHORS' CONCLUSIONS:
There is insufficient evidence to determine whether intravenous anaesthesia with propofol for induction and maintenance of anaesthesia in paediatric outpatients undergoing surgery reduces the risk of postoperative nausea and vomiting and the risk of behavioural disturbances compared with inhaled anaesthesia. This evidence is of poor quality. More high-quality studies are needed to compare the different types of anaesthesia in different subsets of children undergoing ambulatory surgery.

Abstract
BACKGROUND AND AIMS: The study was designed to compare the effects of tramadol administered as an adjunct to bupivacaine in supraclavicular block to that of systemic administration, on postoperative analgesia and rescue analgesic requirement following upper limb surgeries. MATERIAL AND METHODS: A prospective, randomized, controlled, double-blind study was undertaken in patients scheduled for upper limb surgeries under supraclavicular block. All the three group patients received either of the following drugs mixtures: Group A - bupivacaine 0.5%-18 ml + normal saline-7 ml for block and normal saline-10 ml intravenously. Group B - bupivacaine 0.5%-18 ml + normal saline-7 ml mixture for block and tramadol (100 mg) diluted to 10 ml - intravenously. Group C - bupivacaine 0.5%-18 ml + tramadol (100 mg) + normal saline-5 ml mixture and normal saline 10 ml intravenously. The patients were observed for sensory, motor onset along with the duration of sensory and motor block. Patients were monitored for sedation and hemodynamic parameters during intra-operative and postoperative period. Pain-free period and demand for rescue analgesia was noted in all the patients. RESULTS: The study demonstrates that the mixture of tramadol and bupivacaine injected perineurally for supraclavicular brachial plexus blockhastens the onset of sensory block, motor block and provides a longer duration of motor blockade and demand for rescue analgesia as compared to other two groups. CONCLUSIONS: In conclusion, the addition of tramadol to bupivacaine mixtures as an adjunct for supraclavicular brachial plexus block provide better postoperative analgesia for orthopedic upper extremity surgery in comparison to control or systemic tramadol group without any side effects.

Abstract
Background: Ropivacaine is a novel alternative to bupivacaine with the less cardiovascular system and central nervous system toxicity. Clonidine, an alpha 2 agonist, may have benefited patients when it is injected at peripheral nerve sites with local anesthetic ropivacaine. Clonidine is second only to epinephrine as a useful adjuvant for brachial plexus blockade. Objective: A clinical study was carried out to compare the anesthetic effects of ropivacaine alone and clonidine as an adjuvant to ropivacaine in brachial plexus block for upper limb surgeries. Materials and Methods: A comparative, double-blind, prospective, randomized, clinical study was carried out on 60 patients of either sex of American Society of Anesthesiologist physical status I and II, with age group 25-65 years undergoing various orthopedic surgeries of upper limb under supraclavicular brachial plexus block. Patients were randomly allocated to either of the two groups of 30 each. Group-R: Injection ropivacaine 30 ml (0.75%) with 1 ml normal saline. Group-ropivacaine clonidine (RC): Iinjection ropivacaine 30 ml (0.75%) with injection clonidine 1 ml (150 μg). Heart rate, mean arterial pressure, onset and duration of motor and sensory blockade were observed during preoperative, intraoperative and postoperative period. At the end of the study, the data were analyzed using Chi-square test for qualitative data and Student t-test. P < 0.05 was considered significant and P < 0.01 was considered as highly significant.Results: Demographic and hemodynamic data were comparable. Onset of sensory and motor block was significantly earlier in Group-R. Duration of analgesia and motor blockade was prolonged in the RC group. Both groups were observed for the side-effects, which were not significant. Conclusions: Addition of clonidine 150 μm to ropivacaine 0.75% 30 ml delays the onset of sensory and motor blockade while prolongs the postoperative motor blockade and analgesia significantly without producing any clinical significant side-effects in brachial plexus block through supraclavicular approach.
