骶管麻醉与喉罩-七氟醚麻醉在小儿短小手术的对比研究

目的观察骶管阻滞麻醉与喉罩一七氟醚麻醉在小儿短小手术中应用的优缺点。方法2～5岁择期行斜疝或隐睾手术的患儿60例，随机分为静脉复合骶管麻醉组（S），喉罩-静吸麻醉组（L），每组30例。观察患儿术中生命体征、苏醒时间、PACU停留时间、氯胺酮用量、围术期并发症。结果BP、HR和SpO2在两组间比较差异无统计学意义。S组麻醉苏醒时间、PACU停留时间明显长于L组（P〈0．01），S组氯胺酮用量明显多于L组（P〈0．01）。S组术后躁动发生率明显低于L组（P〈0．05）。结论两种方法都可以安全、有效地用于小儿短小手术麻醉，静脉复合骶管阻滞麻醉苏醒时间明较长，但是可以明显降低术后躁动发生率。

A comparision of sacral canal block and sevoflurane anaesthesia with LMA in children undergoing minor surgery

Objective To compare the advantages and disadvantages of sacral canal block and sevoflurane anaesthesia with LMA in children undergoing minor surgery. Methods Sixty children aged 2～5 years,schedule to undergo minor surgical procedures, were divided into sacral canal block (group S) and sevoflurane anaesthesia with LMA (group L). Demographic data, heart rate, non-invasive blood pressure, pulse oximeter oxygen satutraion were recorded for each child. In addition, time from termination of surgery to emergence and duration of stay in the PACU, total dose of ketamine, side effects were recorded. Results The two groups were comparable with respect to demographic data, blood pressure and heart rate. The emergence time and du-ration of stay in the PACU of group S were significantly longer than those of group L. There were significantly more dose of ket-amine in the group S. The incidence of emergence agitation in the L group was significantly higher than that in the group S. Con-clusion The balanced anaesthesia of sacral canal block and intravenous anaesthesia, resulted in a lower incidence of emergence agitation, but there were significantly longer emergence time.
