先天性心脏病术后个体化目标导向镇静治疗

Goal directed sedation therapy after the cardiac surgery

先天性心脏病患儿手术创伤大、术中大多进行体外循环、术后有创操作多，加之环境因素、应激反应等原因，易出现焦虑、烦躁等，导致术后循环不稳定，心率加快，血压上升，不利于术后恢复。因此术后应用镇静药物对患儿实施目标导向镇静治疗，在减轻患者应激反应、维持血流动力学稳定中起重要作用。

Children with congenital heart disease always prone to anxiety and irritability because of huge surgical trauma, using eardiopuhnonary bypass during surgery, invasive procedure comhined with environmental factors, stress response and so on. Those all lead to unstable circulation, increasing heart rate and blood pressure which are not conducive to recover. So the goal directed sedation therapy play a key role to reduce stress response, decrease oxygen consumption and keep circulation sta- ble.
