作者为了观察用布比卡因加芬太尼给小儿作骶管阻滞后,是否影响手术的应激反应,特选择60例(ASA I级)择期行腹股沟疝修补术1～8岁的男儿进行研究。氟烷-50％N2O-O2诱导,置入喉罩,呼气末氟烷浓度1.5％。经由Bain回路行人工辅助通气。维持PETCO24.0～6.5 kPa。然后在侧卧位下行骶管穿刺,按随机双盲法将骶管阻滞分为2组,A组(n
In order to observe the use of bupivacaine plus fentanyl in children with caudal retraction, whether the impact of surgical stress response, the special selection of 60 patients (ASA I grade) choose inguinal hernia repair of 1 to 8-year-old man research.
