Randomized Controlled Trial Clinical Trial
Patient-controlled analgesia versus conventional intramuscular injection: a cost effectiveness analysis.
In previous studies comparing patient-controlled-analgesia and intramuscular pain management have been unable to provide conclusive evidence of the benefits of either method of postoperative pain control. ⋯ While patient-controlled-analgesia was more costly, it was also more effective than conventional on-demand intramuscular opioid injections after laparotomy for gynaecological surgery.
