Objective: To investigate the risk factors for postoperative nausea and vomiting (PONV) in patients receiving fentanyl-based intravenous patient-controlled analgesia (IV-PCA) after gynecologic laparoscopy.
Methods: We retrospectively analyzed the data of 88 patients who underwent laparoscopic surgery and received postoperative fentanyl-based IV-PCA. Patient background characteristics and clinical variables were analyzed using univariate and multivariate analyses.
Results: In the univariate analysis, patient weight (<50 kg and> 50 kg) was found to be the dominant factor, and in the multivariate analysis, the amount of fentanyl used during surgery (<0.3 mg and> 0.3 mg) was the dominant factor.
Conclusions: This study showed that patient's body weight (>50 kg) and the amount of fentanyl used during surgery (0.3 mg or more) may be risk factors for the development of PONV in patients receiving fentanyl-based IV-PCA after gynecological laparoscopy.
