The analgesic efficacy of a single intramuscular dose of 75 mg diclofenac given after elective Caesarean section was studied in 50 women in a double-blind randomised manner using a patient-controlled analgesia system. The mean 18 h papavaretum consumption of the placebo group was significantly greater (91.4 mg compared to 61.4 mg). Subjective experience of pain and observed sedation were significantly greater in the control group up to 6 h after operation.
采用患者自控镇痛系统，以双盲随机方式对50名择期剖宫产术后单次肌内注射75毫克双氯芬酸的镇痛效果进行了研究。安慰剂组18小时的罂粟碱消耗量显著更高（分别为91.4毫克和61.4毫克）。术后6小时内，对照组的疼痛主观体验和观察到的镇静程度均显著更高。
