[Clinical assessment of the effect of intravenous patient controlled intravenous analgesia and epidural patient controlled epidural analgesia in postoperative analgesia].

OBJECTIVE: To compare the clinical effect and side-effect of intravenous patient controlled intravenous analgesia (PCIA) with patient controlled epidural analgesia (PCEA). METHODS: Two hundred and forty postoperative patients, who were randomly divided into three groups: group PCIA, group PCEA and control, 80 cases for each group, and the recovery of bowel movement, urinary retention, nausea, vomiting, pruritus, respiratory depression, postpartum hemorrhage, lactation and recovery of uterus were observed after operation. RESULTS: Overall patients in two PCA groups were satisfied with the postoperative analgesia. The incidence of urinary retention in group PCIA were significantly lower than that in group PCEA(P < 0.05). The recovery of bowel movement in group PCEA (17.51 +/- 10.33) was much bigger than that in group PCIA (28.70 +/- 16.36) (P < 0.05). There were no remarkable differences between two PCA groups in nausea, vomiting, respiratory depression and pruritus (P > 0.05). There were no remarkable differences between two PCA groups and control in the incidence of postpartum hemorrhage, lactation and recovery of uterus. CONCLUSIONS: Both PCIA and PCEA have excellent analgesic effect. PCIA has lower incidence of urinary retention, and has higher sedative incidence compared with PCEA.
