| Summary: | Introduction
Prevalence and tobacco-related perioperative complications have been
largely reported. The impact of vaping (e-cigarette use) on the perioperative
period has been rarely evaluated. The purpose of this multicentre cross-sectional
survey was to assess the prevalence of vaping and behaviour of patients undergoing
elective surgery.
Methods
After institutional review board committee and patient approvals, patients
(aged ≥18 years) scheduled for elective non-cardiac surgery in six French hospitals
were assessed preoperatively. Demographic characteristics, and information on
vaping, smoking or dual-use status and consumption were reported.
Results
In six centres, 1712 eligible patients were approached and 1664 patients
were included in this study from June 2016 to January 2017. Of these, 62 patients
used e-cigarettes in the preoperative period (3%; 95% CI: 2–4), including 24
exclusive e-cigarette users (1%; 95% CI: 1–2), 38 dual-users (2%; 95% CI: 2–3)
and 365 smokers (22%; 95% CI: 20–24). Vapers were older than smokers (53 vs
47 years old; p=0.01). During the preoperative period, 12 patients (1%) reported
vaping the morning of surgery.
Conclusions
In the preoperative period, vaping was ten-fold less prevalent than
smoking. Although the clinical relevance may be weak, further research is needed
to explore the real impact of vaping on patients’ outcomes and to elaborate on
clinical recommendations.
