Study summary

Prospective observational study evaluating the incidence, and qualifying the types, of perioperative pulmonary complications in patients that vape.

Read the detailed description

The primary objective of our study is to determine the rate at which patients that vape or use e-cigarettes experience perioperative pulmonary complications during and following general anesthesia. Complications of interest will include postoperative atelectasis with hypoxemia necessitating oxygen therapy, pneumothorax, pneumonia, bronchospasm, bronchospasm requiring bronchodilator therapy, exacerbation of underlying pulmonary disease, pneumonia, ARDS, and acute respiratory failure. Hospital course, including prolonged PACU stay, prolonged hospital admission for inpatients, and rate of ICU admissions, will also be investigated.

A secondary objective will be to further investigate and include the relationship between vaping cessation timeline in the preoperative period and the occurrence of PPCs, which is similarly underreported in the literature. Furthermore, the study will assess how effectively anesthesia providers are screening for vaping or e-cigarette use as part of the preoperative evaluation, given that "it is unclear whether anesthesiologists and surgeons routinely ask patients explicitly about vaping" in the pre-operative setting. This lack of representative screening for vaping further obscures an understanding of the relationship between vaping, vaping cessation, and PPCs.

What researchers measure

Primary outcomes

  1. Perioperative pulmonary complications

    Complications of interest will include postoperative atelectasis with hypoxemia necessitating oxygen therapy, pneumothorax, pneumonia, bronchospasm, bronchospasm requiring bronchodilator therapy, exacerbation of underlying pulmonary disease, pneumonia, ARDS, and acute respiratory failure. Hospital course, including prolonged PACU stay, prolonged hospital admission for inpatients, and rate of ICU admissions, will also be investigated.

    Time frame: From the initiation of general anesthesia through postoperative day seven.

Secondary outcomes

  1. Vaping cessation timeline

    Includes the relationship between vaping cessation timeline in the preoperative period and the occurrence of postoperative pulmonary complications

    Time frame: From the initiation of general anesthesia through postoperative day seven.
