Certified Registered Nurse Anesthetists' Adherence to an Intraoperative Lung Protective Ventilation Protocol.

Journal Article (Multicenter Study;Journal Article)

The clinical application of intraoperative mechanical ventilation is highly variable and often determined by providers' attitudes and preferences, rather than evidence. Ventilation strategies using high tidal volumes (VT ) with little to no positive end-expiratory pressure (PEEP) are associated with lung injury, increasing the risk of postoperative pulmonary complications. Literature demonstrates that applying lung protective ventilation (LPV) strategies intraoperatively, including low VT , individualized PEEP, and alveolar recruitment maneuvers, can reduce the risk of postoperative pulmonary complications. This multicenter quality improvement project aimed to develop and implement an LPV protocol to increase nurse anesthetists' knowledge and adherence to LPV strategies in adults undergoing laparoscopic cholecystectomy. The anesthesia providers were educated about LPV strategies and their intraoperative application to individualize ventilation settings based on patient comorbidities and body habitus. Adherence was determined by collecting ventilator data and evaluating the data using logistic regression. The overall protocol adherence significantly increased (P=.01). Additionally, there was a significant improvement in adherence to each individual component of the protocol (all P<.05) except for VT . Decreasing the oxygen concentration administered during maintenance and emergence was the most commonly adopted practice (P<.0001). This project demonstrates that education and a standardized protocol can increase the use of intraoperative LPV strategies.
