术前小儿静脉穿刺行吸入麻醉诱导效果的研究

针对术前小儿静脉穿刺难度大，成功率低的问题，选择90例患儿，随机分为3组，A组为对照组，B组穿刺前经面罩吸入氧化亚氮和氧气，C组在B组基础上，加用七氟醚，观察患儿穿刺时的反应及穿刺情况，结果：C组反应最轻，穿刺成功率也最高，且所需时间最短，与A组和B组相比，均有统计学意义（P＜0．05），提出，在严密的监测下，实施吸入麻醉诱导后行静脉穿刺是可行的。

A Study on Induction Effects of Inhalation Anesthesia Before Venipuncture in Pre-operative Children

In view of the fact that venipucture in pre-operative children were with some difficulties and low success rate, 90 cases of children were randomly divided into 3 groups. Patients in group A were taken as control,patients in group B were given nitrous oxide and oxygen inhalation before venipuncture, and patients in group C were given nitrous oxide and oxygen inhalation plus sevoflurane inhalation before venipuncture. Then reactions to venipuncture of these three groups of children were observed. Results: compared to patients in group A and group B, patients in group C had the least reaction, the highest success rate of venipuncture, and the shortest time needed to perform it. There are statistical differences between group A or group B and group C,suggesting that under close monitoring it is feasible to perform venipuncture in pediatric pre-operative patients after inhalation anesthesia.
