A 26-yr-old morbidly obese parturient with a body mass index of 62 kg.m-2 underwent elective cesarean section for preeclampsia under epidural anesthesia. The distance between the skin and the epidural space was about 9 cm at the L3-4 interspace via mid approach. Epidural catheter was inserted 5 cm cephalad in the sitting position and a bolus of 17 ml of mepivacaine 1.5% was given in the supine position. The T5 level of analgesia was obtained 10 min later. Forty minutes after the start of the surgery, a female newborn weighing 3,206 g was delivered with an Apgar score 8 at 1 min and 9 at 5 min. Throughout the surgery, sufficient analgesia was obtained and any complications such as severe hypotension and respiratory depression did not develop. Postoperative pain was relieved sufficiently with a continuous epidural infusion of 0.25% bupivacaine at a rate of 0.5 ml.h-1 for two days. Both maternal and neonatal postpartum courses were uneventful. In conclusion, elective cesarean section in a morbidly obese parturient was successfully managed with epidural anesthesia. This indicates that an elective cesarean section under epidural anesthesia reduce the risk of perioperative complications in a morbidly obese parturient.
一名26岁、体重指数为62kg·m⁻²的病态肥胖产妇因先兆子痫在硬膜外麻醉下行择期剖宫产术。经中路在L3 - 4椎间隙处,皮肤与硬膜外腔的距离约为9cm。在坐位时将硬膜外导管向头端插入5cm,然后在仰卧位给予17ml 1.5%的甲哌卡因推注。10分钟后获得T5节段的镇痛效果。手术开始40分钟后,一名体重3206g的女婴出生,1分钟时阿氏评分8分,5分钟时9分。在整个手术过程中,获得了充分的镇痛效果,未出现严重低血压和呼吸抑制等并发症。术后通过以0.5ml·h⁻¹的速率持续硬膜外输注0.25%布比卡因两天,充分缓解了疼痛。母婴产后过程均顺利。总之,病态肥胖产妇的择期剖宫产术通过硬膜外麻醉成功实施。这表明硬膜外麻醉下的择期剖宫产术可降低病态肥胖产妇围手术期并发症的风险。
