An elective left flank Caesarean operation was performed on 56 Hereford cattle and the influence of various surgical techniques on the postoperative progress assessed. A paravertebral nerve block produced effective analgesia in all layers of the abdominal wall of all cattle. In contrast, tissue infiltration, in the form of an inverted L block, did not produce analgesia of the peritoneum and was generally only partly effective in the muscle layers of fat animals. The use of spasmolytic drug facilitated handling of the uterus. Xylazine, when given to unmanageable animals, noticeably increased uterine tone even when used in conjunction with a spasmolytic. Three animals (5.4%) died from generalised peritonitis. Peritoneal adhesions developed in 29 animals (51.8%) and minor wound dehiscence and/or suture infection occurred in 8 animals (14.1%). Postoperative subcutaneous emphysema developed in ;23 cattle (41%). The absence of sutures in the peritoneum was associated with a significant increase in the occurrence of subcutaneous emphysema. Although the prevalence of retained foetal membranes was high this did not seem to influence the postoperative progress of the animal.
对56头赫里福德牛进行了择期左侧剖腹产手术，并评估了各种手术技术对术后恢复进程的影响。椎旁神经阻滞在所有牛的腹壁各层均产生了有效的镇痛效果。相比之下，倒L形阻滞形式的组织浸润并未产生腹膜镇痛效果，并且在肥胖动物的肌肉层通常仅部分有效。使用解痉药物便于子宫的处理。当给难以控制的动物使用甲苯噻嗪时，即使与解痉药联合使用，子宫张力也会明显增加。3头动物（5.4%）死于弥漫性腹膜炎。29头动物（51.8%）发生了腹膜粘连，8头动物（14.1%）出现了轻微的伤口裂开和/或缝线感染。23头牛（41%）出现了术后皮下气肿。腹膜不缝合与皮下气肿发生率的显著增加有关。尽管胎膜残留的发生率很高，但这似乎并未影响动物的术后恢复进程。
