Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

PCIA-PONV Group

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.
