Comparative StudyCardiopulmonary resuscitation performance during simulator-based trainings: a comparative retrospective analysis of adherence to 2005 and 2010 guidelines.
New cardiopulmonary resuscitation (CPR) guidelines have been published in 2010 emphasizing the importance of minimizing interruptions during chest compression. The aim of our study was to compare the simulator-based CPR training performance of physicians not specialized in anaesthesia and intensive care nurses before and after implementation of new resuscitation guidelines. ⋯ Non-anesthesiological physicians and intensive care nurses training demonstrated an improved CPR performance in a high-fidelity human patient simulator with respect to the median cardiac output and duration of no-flow-time when 2010 CPR guidelines were applied.

The volume and pH of residual pharyngeal fluid aspirated from the TaperGuard Evac™ Endotracheal Tube following elective surgery: a prospective pilot study.
Oropharyngeal suctioning prior to extubation aims to minimize postextubation tracheal soiling from remaining fluid. We investigated the amount and nature of any fluid remaining after such suctioning and contributing factors. ⋯ ASA I - III patients undergoing elective surgery under general anesthesia with endotracheal intubation participated in this prospective observational pilot study. Following oropharyngeal suctioning immediately prior to extubation, a dedicated port of the endotracheal tube (TaperGuard Evac™ Endotracheal Tube) was aspirated. The amount and pH of residual fluid was recorded. Data collection included age, sex, body mass index, comorbidities, ASA status, procedure type and duration. The Chi-Square, Wilcoxon Rank-Sum, t-tests, and univariate regression analysis were used as appropriate. Results: Ninety-eight patients completed the study. The mean aspirated volume in 38 (38.8%) patients was 0.9 ± 1.3 mL and sixty patients (61.2%) had no aspirate. A body mass index of ≥ 30 kg/m2 was associated with the presence of fluid (P=0.03), and a higher volume (P=0.03). The fluid pH was 7 ± 0.81 (mean ± SD). A duration of surgery ≥ 120 minutes predicted a lower pH. Conclusion: The prevalence and amount of residual fluid after oropharyngeal suctioning was low and likely clinically insignificant. A higher body mass index was associated with a higher incidence and volume of residual fluid. Longer procedure duration determined a slightly lower pH, with a mildly acidic pH range. The possibility of a lower fluid pH after prolonged surgery contributing to postoperative sore throat via mucosal irritation warrants investigation.
