Intraoperative Sufentanil Consumption and the Risk of Postoperative Nausea and/or Vomiting: A Retrospective Observational Study.

Abstract

INTRODUCTION:

Post-operative nausea and/or vomiting (PONV) is a common post-operative adverse reaction and has been associated with post-operative sufentanil injection. The assessment of the relationship between intraoperative opioid consumption and PONV has been understudied. This study examined the relationship between intraoperative sufentanil administration and PONV.

METHODS:

This was a single-center retrospective observational study. Patients who underwent video-assisted thoracoscopic surgery under general anesthesia with the preoperative thoracic paravertebral block between January 2017 and June 2020 at the Peking University People's Hospital were recruited for this study. Patients were grouped into two groups according to whether or not PONV occurred on postoperative day 1 (POD1). The factors associated with PONV were analyzed using logistic regression.

RESULTS:

A total of 2733 patients, 1510 males and 1223 females, were included in this study. Among them, 143 patients developed PONV, a 5.2% (143/2733) PONV incidence. Logistic regression analysis showed that female, nonsmoking, sufentanil patient-controlled intravenous analgesia (PCIA), POD1 opioids consumption, and a time-weighted average of intraoperative sufentanil (twSuf) were associated with PONV. All patients were further divided into four subgroups based on intraoperative twSuf. Logistic regression analysis revealed that twSuf higher than 0.21 μg kg-1 h-1 was an independent risk factor for PONV.

CONCLUSIONS:

Intraoperative sufentanil injection with a twSuf higher than 0.21 μg kg-1 h-1 increased the risk of PONV in patients undergoing thoracoscopic surgery under general anesthesia after a preoperative thoracic paravertebral block.
