连续腰麻分娩镇痛优于硬膜外,导管内注阿片碱镇痛可靠,全身吸收少,无低血压或运动阻滞,也无全身中毒与全脊麻的危险。研究20例经32号导管置入鞘内,注入双醋吗啡(Diamorphine,C,与丁哌卡因(bupivacaine,B)分娩镇痛效果。20例除外宫口>4cm,非单胎,糖尿病或 ASAⅢⅣ以及分娩已接受阿片碱镇痛的孕妇。输液,于腰2-3间隙用26号针侧入达蛛网膜下腔,置入32号导管3 cm。记录置管时间,用视觉模拟尺评价
Continuous spinal anesthesia analgesia is superior to epidural catheter opioid analgesic reliable, less systemic absorption, no hypotension or motor block, nor the risk of systemic poisoning and spinal anesthesia. Twenty patients underwent intubation with catheterization of diamorphine (C) and bupivacaine (B) for labor analgesia in 20 cases, except 20 cases with uterine cervix> 4 cm, non-singleton, diabetes or ASAⅢⅣ and pregnant women who had given opioid analgesia during labor.Transfusion was performed on the 26th needle in the lumbar 2-3 space and into the subarachnoid space with a catheterization of 32 cm in diameter.The catheterization time was recorded and evaluated by visual analogue scale
