腹腔镜手术是一种新型的、微创的手术方式,现已被我院外科广泛采用,特别是在小儿阑尾炎和腹股沟斜疝中的应用。虽然腹腔镜具有很好的优越性和微创性,但它对患儿生理环境仍存在两大影响因素:一是CO2人工气腹;二是体位改变及快速气腹时,患儿心血管反应明显。这给患儿带来一定的危险性,为了提高腹腔镜手术期间麻醉的安全性,把患儿围术期的风险降到最低,我院对腹腔镜手 Laparoscopic surgery is a new, minimally invasive surgical approach, has been widely used in our hospital surgery, especially in children with appendicitis and inguinal hernia. Although laparoscopic has good advantages and minimally invasive, but it still has two major physiological factors in children with environmental factors: First, CO2 artificial pneumoperitoneum; Second, changes in body position and rapid pneumoperitoneum, cardiovascular disease in children obvious. This gives children a certain degree of risk, in order to improve the safety of anesthesia during laparoscopic surgery, to minimize the risk of perioperative period in children, our hospital laparoscopic hand
