P Pu ur rp po os se e: : To compare the efficacy of acupressure wrist bands and ondansetron for the prevention of postoperative nausea and vomiting (PONV).M Me et th ho od ds s: : One hundred and fifty ASA I-II, patients undergoing elective laparoscopic cholecystectomy were included in a randomized, prospective, double-blind and placebo-controlled study. Patients were divided into three groups of 50. Group I was the control; Group II received ondansetron 4 mg iv just prior to induction of anesthesia; in Group III acupressure wristbands were applied at the P6 points. Acupressure wrist bands were placed inappropriately in Groups I and II. The acupressure wrist bands were applied 30 min prior to induction of anesthesia and removed six hours following surgery. Anesthesia was standardized. PONV were evaluated separately as none, mild, moderate or severe within six hours of patients' arrival in the postanesthesia care unit and then at 24 hr after surgery by a blinded observer. If patients vomited more than once, they were given 4 mg ondansetron iv as the rescue antiemetic. Results were analyzed by Z test. A P value of < 0.05 was taken as significant. R Re es su ul lt ts s: : The incidence of PONV and the requirement of rescue medication were significantly lower in both the acupressure and ondansetron groups during the first six hours.C Co on nc cl lu us si io on n: : Acupressure at P6 causes a significant reduction in the incidence of PONV and the requirement for rescue medication in the first six hours following laparoscopic cholecystectomy, similar to that of ondansetron 4 mg iv. Objectif : Comparer l'efficacité des bandes d'acupression et de l'ondansétron comme prévention des nausées et vomissements postopératoires (NVPO). Méthode : Cent cinquante patients d'état physique ASA I-II devant subir une cholécystectomie laparoscopique ont été recrutés pour une étude prospective, randomisée et à double insu contre placebo. Ils ont été répartis en trois groupes de 50. Le groupe I a été le groupe témoin; les patients du groupe II ont reçu 4 mg iv d'ondansétron juste avant l'induction de l'anesthésie; chez les patients du groupe III, on a appliqué des bandes d'acupression aux point P6. Des bandes d'acupression ont été placées de façon inappropriée chez les patients des groupes I et II. Les bandes ont été appliquées 30 min avant l'induction

This is the first of two articles describing the uses of point of care testing in coagulation management. The first article describes the basis of thromboelastography with its physical principles and uses. The second describes discussions of case studies in clinical scenarios.

An unusual case of massive oropharyngeal swelling and macroglossia occurring after cervical spine surgery performed on a patient in the prone position is described. Possible etiological factors are reviewed, and measures to prevent these complications are suggested.

ImportanceWhether selective decontamination of the digestive tract (SDD) reduces mortality in critically ill patients remains uncertain.ObjectiveTo determine whether SDD reduces in-hospital mortality in critically ill adults.Design, Setting, and ParticipantsA cluster, crossover, randomized clinical trial that recruited 5982 mechanically ventilated adults from 19 intensive care units (ICUs) in Australia between April 2018 and May 2021 (final follow-up, August 2021). A contemporaneous ecological assessment recruited 8599 patients from participating ICUs between May 2017 and August 2021.InterventionsICUs were randomly assigned to adopt or not adopt a SDD strategy for 2 alternating 12-month periods, separated by a 3-month interperiod gap. Patients in the SDD group (n = 2791) received a 6-hourly application of an oral paste and administration of a gastric suspension containing colistin, tobramycin, and nystatin for the duration of mechanical ventilation, plus a 4-day course of an intravenous antibiotic with a suitable antimicrobial spectrum. Patients in the control group (n = 3191) received standard care.Main Outcomes and MeasuresThe primary outcome was in-hospital mortality within 90 days. There were 8 secondary outcomes, including the proportion of patients with new positive blood cultures, antibiotic-resistant organisms (AROs), and Clostridioides difficile infections. For the ecological assessment, a noninferiority margin of 2% was prespecified for 3 outcomes including new cultures of AROs.ResultsOf 5982 patients (mean age, 58.3 years; 36.8% women) enrolled from 19 ICUs, all patients completed the trial. There were 753/2791 (27.0%) and 928/3191 (29.1%) in-hospital deaths in the SDD and standard care groups, respectively (mean difference, −1.7% [95% CI, −4.8% to 1.3%]; odds ratio, 0.91 [95% CI, 0.82-1.02]; P = .12). Of 8 prespecified secondary outcomes, 6 showed no significant differences. In the SDD vs standard care groups, 23.1% vs 34.6% had new ARO cultures (absolute difference, −11.0%; 95% CI, −14.7% to −7.3%), 5.6% vs 8.1% had new positive blood cultures (absolute difference, −1.95%; 95% CI, −3.5% to −0.4%), and 0.5% vs 0.9% had new C difficile infections (absolute difference, −0.24%; 95% CI, −0.6% to 0.1%). In 8599 patients enrolled in the ecological assessment, use of SDD was not shown to be noninferior with regard to the change in the proportion of patients who developed new AROs (−3.3% vs −1.59%; mean difference, −1.71% [1-sided 97.5% CI, −∞ to 4.31%] and 0.88% vs 0.55%; mean difference, −0.32% [1-sided 97.5% CI, −∞ to 5.47%]) in the first and second periods, respectively.Conclusions and RelevanceAmong critically ill patients receiving mechanical ventilation, SDD, compared with standard care without SDD, did not significantly reduce in-hospital mortality. However, the confidence interval around the effect estimate includes a clinically important benefit.Trial RegistrationClinicalTrials.gov Identifier: NCT02389036

Nasogastric tube placement can cause ulceration and bleeding from the nose, pharynx, esophagus, and stomach. Its accidental placement into the tracheopulmonary system may lead to pneumothorax, hemothorax, or even death. We report a case of its knotting over the epiglottis, leading to life-threatening respiratory distress.
