分娩镇痛中自控镇痛技术的应用

自控镇痛技术是以药代动力学与药效动力学为基础,以血浆或效应室药物浓度为指标,由微机调控给药速度以达到一定镇痛深度,并允许产妇根据自身镇痛需求自行给药的一种方法。近年来临床应用愈加受到重视,方式多样,使用方便,在分娩镇痛中的应用亦较为成熟。多项研究结果表明,此技术可有效满足产妇镇痛的需要,且有运动阻滞较轻、局麻药物用量减少及对产妇和胎儿相对安全等诸多优点,较各种传统镇痛方式有明显优越性。

Application of patient-controlled analgesia in obstetric analgesia

Patient-controlled analgesia(PCA) is such a technique, based on pharmacokinetics and pharmacodynamics, standardized by plasma or effect compartment drug concentration, and regulated by certain process of computer in administrating rate,that provides the patient with self-administrating analgesics referring to the requirement of analgesia. As its safeness and convenience, PCA is widely applied in pain management, including obstetric analgesia. A lot of study suggests that PCA has greater advantages than conventional techniques in obstetric analgesia. For example, PCA provides better pain control, greater patient satisfaction and safeness,lesser motor blockage,lower local anesthetics dose and anesthetists' work loading.
