小儿骶管麻醉用于心导管和心血管造影术

Caudal Anaesthesia in Cardiac Catheterization and Angiocardiography

本文报告骶管麻醉在小儿先天性心脏病心导管和心血管造影术中的应用.骶管麻醉组44例,静脉麻醉12例.结果,骶管麻醉组并发症明显低于单纯静脉麻醉.骶管麻醉不仅有助于导管操作和造影时体位固定,且有利于代谢和血流动力的稳定.

This paper reports the use of caudal anaesthesia in cardiac catheterization and angiocardiaography on children with congenital heart diseases,and the comparison between it and the intravenous anaesthesia on the basis of their angiocardiographic data.In the group of caudal anaesthesia(44 cases),1-1.75% procaine and 0.1-0.15% dicaine solution with adrenaline(1ml /Kg body weight)were given.Intermittent increments of Valium or Ketamine was administered when necessary.Intravenous anaesthesia was applied to 12 cases(Group Ⅱ)with Ketamine and α-hydroxybutyrat or Valium.Results:43.18% of the patients in Group Ⅰ did not require increments of intravenous anaesthetics,but 13 cases Ketamine was given(dosage:0.85-0.49 mg/kg/hr).Ketamine was administered unexceptionally in GroupⅡ with a dosage of 1.61-0.84 mg/kg/hr.There was significant difference between the two groups in the dosage of Ketamie(p<0.02).The caudal anaesthsia group had a much lower occurrence of complications as compared with those who received intravenous anaesthesia alone.The authors considered that caudal anaesthesia is better than intravenous anaethsia in angiocardiography in pediatric cases,for it keeps the pateint well immobulized and makes catheter manipulation easier,and also provides a stable metabolic and haemodynamic condition.
