Randomized Controlled Trial Comparative Study Clinical Trial
Patient-controlled analgesia versus intramuscular analgesic therapy.
The pharmacy and nursing time requirements, quality of postoperative pain control, and cost of patient-controlled analgesia (PCA) and intramuscular (i.m.) analgesic therapy were studied. All timings were conducted with a stopwatch on a single nursing unit that primarily receives gynecologic surgery patients. The various work elements involved in each type of therapy were timed individually. ⋯ The median pain scores were moderate for i.m. patients and mild for PCA patients. Scores tended to be lower for PCA patients at 16 and 20 hours. Although equal numbers of patients in the two groups experienced nausea, i.m. patients needed more doses of antiemetics than PCA patients.(ABSTRACT TRUNCATED AT 250 WORDS)
