Clinical Trial Summary

The purpose of this study is to identify the risk factors for postoperative nausea and vomiting (PONV) in surgical patients undergoing patient-controlled intravenous analgesia (PCIA).

Description:

Our study was a retrospective study, including patients who underwent surgery at Peking Union Medical College Hospital from July 1, 2023 to October 31, 2023 and underwent PCIA. Patient characteristics, past medical history, surgical information, intraoperative medication information, postoperative analgesia follow-up information were obtained through the electronic medical record system. The patients were divided into PCIA-PONV group and non-PCIA-PONV group depending on the occurrence of nausea and vomiting during PCIA, and all patients was also divided into PCIA-POV group and non-PCIA-POV according to whether vomiting occurred. Multivariate logistic regression analysis was used to identify the risk factors for PCIA-PONV and PCIA-POV.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	PCIA-PONV	Patient-controlled intravenous analgesia (PCIA) was provided after surgery and a dedicated anesthesiologist conducted follow-up. Routine bedside visits were conducted twice a day during the PCIA procedure to evaluate the patient's postoperative nausea and vomiting. The degree of nausea was evaluated using the visual analogue scale (VAS), with 0 indicating no nausea or vomiting and 10 indicating the most severe form of unbearable nausea or vomiting. When the PONV score was greater than 4 or vomiting occurs, it was defined as PCIA-PONV.	During the PCIA procedure after surgery
Secondary	PCIA-POV	Patient-controlled intravenous analgesia (PCIA) was provided after surgery and a dedicated anesthesiologist conducted follow-up. Routine bedside visits were conducted twice a day during the PCIA procedure to evaluate the patient's postoperative nausea and vomiting. When vomiting occurs, it was defined as PCIA-POV.
