About

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).

Full 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.

Trial design

1,371 participants in 2 patient groups

PCIA-PONV Group
Description:
Patient-controlled intravenous analgesia (PCIA) will be used after surgery. Patients will receive dedicated follow-up. Routine bedside visits will be conducted twice daily after surgery to assess postoperative nausea and vomiting (PONV). The severity of nausea will be evaluated using the Visual Analogue Scale (VAS), where 0 indicates no nausea and vomiting, and 10 represents the most unbearable nausea and vomiting. When the PONV score is >0 or vomiting occurs, it is defined as the PCIA-PONV group.
Treatment:
Other: No intervention
None PCIA-PONV Group
