从1993年5月开始,有目的地对剖腹探查不能切除的胰腺癌、肝癌等病例,在剖腹手术的同时,在腹腔内直视下应用酒精阻滞腹腔神经丛镇痛。直视穿刺定位准确、简化操作,可避免和减少术后再用其它镇痛方法。现报告如下。 1 解剖特点及穿刺方法 1.1 应用解剖:腹腔神经丛位于T_(12)与L_1椎体前方,腹主动脉、下腔静脉与肠系膜上动脉根部呈网状缠裹。丛内有一内脏神经节贴靠在腹腔动脉干两侧,膈肌角前,下腔静脉与脾血管后 From May 1993, a targeted exploratory laparotomy for unresectable cases of pancreatic cancer, liver cancer, and laparotomy was performed, and alcohol was used to block analgesia in the celiac plexus under direct intra-abdominal exposure. Direct puncture positioning accuracy, simplified operation, can avoid and reduce postoperative re-use of other analgesic methods. The report is as follows. 1 Anatomical features and puncture methods 1.1 Applied anatomy: The celiac plexus is located in front of the T_(12) and L_1 vertebral bodies, and the abdominal aorta, the inferior vena cava, and the superior mesenteric artery are entangled in a mesh. There is a splanchnic ganglion in the plexus resting on both sides of the celiac artery, before the diaphragm angle, after the inferior vena cava and splenic vessels
