Randomized Controlled Trial Comparative StudyRandomized trial comparing 3 methods of postoperative analgesia in gynecology patients: patient-controlled intravenous, scheduled intravenous, and scheduled subcutaneous.
The objective of the study was to determine whether any of 3 routes of opioid administration (patient-controlled analgesia [PCA], scheduled intermittent intravenous [i.v.], or scheduled intermittent subcutaneous [s.q.]) provides superior pain relief and satisfaction among patients undergoing abdominal gynecologic surgery. ⋯ Given these findings as well as those in previous literature, no specific method of postoperative analgesia appears to be superior.
