Initially introduced as a safer alternative to smoking, electronic cigarettes (e-cigarettes) and vaping have since been associated with lung injury. Nevertheless, there is limited perioperative data on their potential contribution to the harmful effects of mechanical ventilation on the lungs. We hypothesized that, in adults undergoing noncardiothoracic surgeries, preoperative vaping/e-cigarette use is associated with hypoxemia during the first postoperative hour, and with an increased incidence of intraoperative and postoperative pulmonary complications. ⋯ Vaping/e-cigarette use was neither associated with clinically significant hypoxemia during the first hour in the postanesthesia care unit nor with an increase in pulmonary complications. Nevertheless, our findings cannot definitively exclude the deleterious effects of vaping and e-cigarette use on the lungs, and anesthesiologists should consider potential perioperative complications.

There is significant variability in the application of positive end-expiratory pressure (PEEP) in patients undergoing invasive mechanical ventilation. There are numerous studies assessing methods of determining optimal PEEP, but many methods, patient populations, and study settings lack high-quality evidence. Guidelines make no recommendations about the use of a specific method because of equipoise and lack of high-quality evidence. We conducted a scoping review to determine which methods of determining optimal PEEP have been studied and what gaps exist in the literature. ⋯ Open Science Framework ( https://osf.io/atzqc ); first posted, 19 July 2022.

Comparative Study
Postoperative analgesic consumption for primary versus first repeat Cesarean delivery: a historical cohort study.
It is unclear if postoperative pain experience and opioid consumption differ in patients undergoing primary vs repeat Cesarean delivery (CD) as prior studies have yielded conflicting results and none used the same patients as their own controls. We sought to compare opioid consumption and pain scores in patients undergoing both a primary and a first repeat CD, using the same patients as their own controls. ⋯ In this retrospective study, we found no differences in postoperative opioid consumption or reported pain scores in patients who underwent both a primary and a first repeat CD.
