吸入麻醉诱导用于手术患儿静脉穿刺效果观察

目的：提高手术患儿术前静脉穿刺一次成功率，缩短术前准备时间，减轻患儿痛苦，方法：将90例手术患儿分为A，B，C三组各30例，A组于清醒状态下行静脉穿刺；B组经面罩下吸入氧化亚氮和氧气，2．5－3min后行静脉穿刺，C组在B组的基础上再吸入七氟醚后行静脉穿刺。结果：C组所用穿刺时间最短（与A，B组比较，均P＜0．01），一次穿刺成功率高（与A组比较，P＜0．01），B组次之；A组最差。结论：手术患儿静脉穿刺前运用吸入麻醉诱导技术可提高一次穿刺成功率，缩短术前准备时间，尤其适用于术前害怕注射或开放静脉有困难的患儿。

Efficacy of Inhalation Induced Anesthesia before Venipuncture in Operative Children

Objective To increase the successful rate of preoperative venipuncture in operative children and shor ten the time of preoperative preparation. Methods Ninety children receiving operation were divided into groups A, B and C ( n= 30 each). In the group A, the children receiving venipuncture under conscious state; In the group B, the children inhaled nitrous oxide and oxygen under a mask 2.5 to 3 min followed by venipuncture; In the group C, the children inhaled sevoflurane besides the anesthetics used in the group B followed by venipuncture. Results The time of venipuncture in the group C was the shortest (as compared with groups A and B, both P <0 01) and the successful rate of venipuncture was higher (as compared with groups A, P <0 01). Conclusion The use of inhalation induced anesthesia technique before venipuncture in the operative children could increase the successful rate of venipuncture, shorten the time of pre operation preparation, especially for those fear of injection or opening veins difficult before operation.
