摘要

Ninety paturients undergoing elective cesarean section were included in this randomized study to compare the influence of the injected volume of epidural morphine (EM) on postoperative analgesia. Three similar groups of patients (n = 30 each) received 2 mg EM in 2 ml, 10 ml, and 20 ml saline respectively one hour after the last dose of 2% lidocaine. Paln scores (0-10) at rest (including uterine contraction pal at the 2^(nd), 4^(th), 8^(th) 12^(th), 18^(th), and 24^(th) were compared among the three groups. There were no statistically significant dimerences of pain score among the three groups although lower paln score was present in the 20 ml group since the 8^(th) h and thereafter. Regarding the number of patients who requested additional meperidine for pain relief 3 in 2 ml group, 2 in 10 ml group and 1 in 20 ml group respectively. The result may suggest that the influence of the injected volume of EM on postcesarean analgesia is not obvious.
