In-hospital mortality of patients requiring unplanned postoperative ventilatory support: a multicenter observational study.

Background: Most patients who are admitted non-intubated to surgery are extubated at surgery conclusion. Yet, 1-2% require unplanned postoperative ventilatory support. The outcome of these patients has not been thoroughly evaluated to date and is the focus of the present study.

Bradycardia During Laparoscopic Surgeries: A Retrospective Cohort Study.

Background: A recent analysis found bradycardia during laparoscopy as a potential early warning sign of cardiac arrest. Knowledge regarding bradycardia frequency and its consequences during laparoscopy is limited.

Methods: Using the computerized record database, files of 9915 patients undergoing laparoscopic surgery, between June 2008 and August 2013 at a tertiary, academic medical center, were screened for intraoperative bradycardia (heart rate <50 beats/min for at least three consecutive measures).
