Randomized Controlled Trial Multicenter Study
Individualized Fluid Management Using the Pleth Variability Index: A Randomized Clinical Trial.
The present trial was designed to assess whether individualized strategies of fluid administration using a noninvasive plethysmographic variability index could reduce the postoperative hospital length of stay and morbidity after intermediate-risk surgery. ⋯ Among intermediate-risk patients having orthopedic surgery with general anesthesia, fluid administration guided by the plethysmographic variability index did not shorten the duration of hospitalization or reduce complications.

Multicenter Study Observational Study
Incidence and Classification of Nonroutine Events during Anesthesia Care.
A nonroutine event is any aspect of clinical care perceived by clinicians or trained observers as a deviation from optimal care based on the context of the clinical situation. The authors sought to delineate the incidence and nature of intraoperative nonroutine events during anesthesia care. ⋯ This study describes characteristics of intraoperative nonroutine events in a cohort of cases at three academic hospitals. Nonroutine event-containing cases were commonly associated with patient impact and injury. Thus, nonroutine event monitoring in conjunction with traditional error reporting may enhance our understanding of potential intraoperative failure modes to guide prospective safety interventions.

Risk Factors for Failure to Rescue in Myocardial Infarction after Noncardiac Surgery: A Cohort Study.
Compared to other perioperative complications, failure to rescue (i.e., death after suffering a complication) is highest after perioperative myocardial infarction (a myocardial infarction that occurs intraoperatively or within 30 days after surgery). The purpose of this study was to identify patient and surgical risk factors for failure to rescue in patients who have had a perioperative myocardial infarction. ⋯ Routinely identified patient and surgical factors predict risk of failure to rescue after perioperative myocardial infarction.
