近年来脊麻由于其确切的麻醉效果,在小儿,特别是婴幼儿、新生儿的应用日趋广泛。但是,不少作者报告在婴幼儿青麻期间需应用镇静剂或辅助麻醉。而由于镇静剂和辅助麻醉的应用,在婴幼儿,尤其新生儿常在脊麻手术期间发生呼吸暂停。本文目的在于探讨,若在婴幼儿脊麻应用较大剂量的麻醉剂,是否能够达到较长时间,较高阻滞平面的麻醉,从而避免镇静、辅助麻醉的应用,减少麻醉期间呼吸暂停等并发症的发生。方法:将60例一岁以下,下腹部手术的婴儿均分为四组:第一、第二组分别应用重比重0.5％的丁卡因或
In recent years, spinal anesthesia due to its exact effect, in infants, especially infants and young children, the application of newborn more widely. However, many authors report the need for sedatives or adjunct anesthesia during infancy. And due to the use of sedatives and adjuvant anesthesia, apnea often occurs in infants, especially newborns, during spinal anesthesia. The purpose of this paper is to explore if anesthesia with larger doses of anesthetic in pediatric spinal anesthesia can achieve a longer period of time, higher block anesthesia in plane to avoid sedation, assist the application of anesthesia and reduce complications such as apnea during anesthesia happened. Methods: Sixty infants younger than one year old and underbelly operation were divided into four groups. In the first and second groups, 0.5% tetracaine or 0.5%
