Abstract Injury is still the number 1 killer of children ages 1 to 18 years in the United States (http://www.cdc.gov/nchs/fastats/children.htm). Children who sustain injuries with resulting disabilities incur significant costs not only for their health care but also for productivity lost to the economy. The families of children who survive childhood injury with disability face years of emotional and financial hardship, along with a significant societal burden. The entire process of managing childhood injury is enormously complex and varies by region. Only the comprehensive cooperation of a broadly diverse trauma team will have a significant effect on improving the care of injured children.

El retorno de las píldoras dietéticas arcoiris The return of rainbow diet pills. Cohen PA, Goday A, Swann JP. Am J Public Health. 2012;102(9):1676-86. Author information Abstract The US Food and Drug Administration (FDA) has recently warned consumers about the risks of weight loss supplements adulterated with multiple pharmaceutical agents. Some of these supplements combine potent anorectics, such as amphetamines derivatives, with benzodiazepines, beta-blockers, and other medications to suppress the anorectics' adverse effects. These weight loss supplements represent the most recent generation of rainbow diet pills, named for their bright and varied colors, which date back more than 70 years. Beginning in the 1940s, several US pharmaceutical firms aggressively promoted rainbow pills to physicians and patients. By the 1960s the pills had caused dozens of deaths before the FDA began removing them from the US market. We used a variety of original resources to trace these deadly pills from their origins in the United States to their popularity in Spain and Brazil to their reintroduction to the United States as weight loss dietary supplements. PDF Opciones para sedación para el obeso mórbido en terapia intensiva Sedation options for the morbidly obese intensive care unit patient: a concise survey and an agenda for development. Aantaa R1, Tonner P2, Conti G3, Longrois D4, Mantz J5, Mulier JP6. Multidiscip Respir Med. 2015 Mar 7;10(1):8. doi: 10.1186/s40248-015-0007-2. eCollection 2015. Abstract BACKGROUND: We offer some perspectives and commentary on the sedation of obese patients in the intensive care unit (ICU). DISCUSSION: Sedation in morbidly obese patients should conform to the same broad principles now current in ICU practice. These include a general presumption against benzodiazepines as first-line agents. Opioids should be avoided in any situation where spontaneous breathing is required. Remifentanil is the preferred agent where continuous stable opioid levels using an infusion are required, because of its lack of context-sensitive accumulation. Volatile anaesthetics may be an option for the same reason but there are no substantial, controlled demonstrations of effectiveness/safety in short-term use in the ICU setting. Propofol is a valuable resource in the morbidly obese patients but the duration of continuous sedation should not exceed 6 days, in order to avoid propofol infusion syndrome. Alpha-2 agonists offer a range of theoretically positive features for the sedation of morbidly obese patients, but at present there is a lack of pharmacokinetic data and a critical mass of high-grade clinical data. Dexmedetomidine has the attraction of not causing respiratory depression or obstructive breathing during sedation and its sympatholytic effects should help deliver stable blood pressure and heart rate. Ketamine has a poor tolerability profile in adults so its use in the ICU context is largely confined to paediatrics. CONCLUSION: None of the agents currently available is ideal for every situation encountered in the management of morbidly obese patients. This article identifies additional research needed to place sedation practice of obese patients on a more systematic footing.

The pharmacokinetics of the CYP3A substrate midazolam in morbidly obese patients before and one year after bariatric surgery.  Brill MJ, van Rongen A, van Dongen EP, van Ramshorst B, Hazebroek EJ, Darwich AS, Rostami-Hodjegan A, Knibbe CA. Pharm Res. 2015 Dec;32(12):3927-36. Abstract Bariatric surgery is nowadays commonly applied as treatment for morbid obesity. As information about the effects of this procedure on a drug's pharmacokinetics is limited, we aimed to evaluate the pharmacokinetics of CYP3A probe substrate midazolam after oral and intravenous administration in a cohort of morbidly obese patients that was studied before and 1 year post bariatric surgery. CONCLUSIONS: In this cohort study in morbidly obese patients, systemic clearance was 1.7 times higher 1 year after bariatric surgery, which may potentially result from an increase in hepatic CYP3A activity per unit of liver weight. Although MTT was found to be faster, oral bioavailability remained unchanged, which considering the increased systemic clearance implies an increase in the fraction escaping intestinal first pass metabolism.

Nausea y vomito postoperatorios / Postoperative nausea and vomiting

Guías de consenso para el tratamiento de nausea y vomito post operatorios Consensus Guidelines for the Management of Postoperative Nausea and Vomiting Gan, Tong J. MD, MHS, FRCA; Diemunsch, Pierre MD, PhD; Habib, Ashraf S. MB, FRCA et al. Anesthesia & Analgesia: January 2014 - Volume 118 - Issue 1 - p 85-113  The present guidelines are the most recent data on postoperative nausea and vomiting (PONV) and an update on the 2 previous sets of guidelines published in 2003 and 2007. These guidelines were compiled by a multidisciplinary international panel of individuals with interest and expertise in PONV under the auspices of the Society for Ambulatory Anesthesia. The panel members critically and systematically evaluated the current medical literature on PONV to provide an evidence-based reference tool for the management of adults and children who are undergoing surgery and are at increased risk for PONV. These guidelines identify patients at risk for PONV in adults and children; recommend approaches for reducing baseline risks for PONV; identify the most effective antiemetic single therapy and combination therapy regimens for PONV prophylaxis, including nonpharmacologic approaches; recommend strategies for treatment of PONV when it occurs; provide an algorithm for the management of individuals at increased risk for PONV as well as steps to ensure PONV prevention and treatment are implemented in the clinical setting. PDF Nausea y vomito después de cirugía ortognática Postoperative nausea and vomiting following orthognathic surgery. Phillips C1, Brookes CD2, Rich J3, Arbon J4, Turvey TA2. Int J Oral Maxillofac Surg. 2015 Jun;44(6):745-51. doi: 10.1016/j.ijom.2015.01.006. Epub 2015 Feb 2. Abstract The purpose of this study was to assess the incidence and risk factors associated with postoperative nausea (PON) and vomiting (POV) after orthognathic surgery. A review of the clinical records of consecutively enrolled subjects (2008-2012) at a single academic institution was conducted between 9/2013 and 3/2014. Data on the occurrence of PON and POV and potential patient-related, intraoperative, and postoperativeexplanatory factors were extracted from the medical records. Logistic models were used for the presence/absence of postoperative nausea and vomiting separately. Data from 204 subjects were analyzed: 63% were female, 72% Caucasian, and the median age was 19 years. Thirty-three percent had a mandibular osteotomy alone, 27% a maxillary osteotomy alone, and 40% had bimaxillary osteotomies. Sixty-seven percent experienced PON and 27% experienced POV. The most important risk factors for PON in this series were female gender, increased intravenous fluids, and the use of nitrous oxide, and for POV were race, additional procedures, and morphine administration. The incidence of PON and POV following orthognathic surgery in the current cohort of patients, after the introduction of the updated 2007 consensus guidelines for themanagement of postoperative nausea and vomiting, has not decreased substantially from that reported in 2003-2004.
