针对硬膜外阻滞下剖宫产术中患者有低血压倾向,探讨用血定安预防性扩充血容量,以保持患者血流动力学的稳定。我们在40例硬膜外阻滞下剖宫产术中、麻醉初期,输入血浆代用品血定安与乳酸钠林格氏液作一对比,观察两组间血压、心率的变化。 1 资料与方法 1.1 一般资料:全组40例,年龄23～32岁,ASA Ⅰ～Ⅱ级,无妊娠并发症。随机分为血定安组(A组)、乳酸钠林格氏液组(B组),两组各20例。 1.2 麻醉及输液方法:术前药阿托品0.5mg,苯巴比妥钠0.1g肌注。均选择L2～3间隙穿刺,
In view of the hypotensive tendency of patients under cesarean section under epidural block, the blood volume was prophylactically expanded with blood lead to maintain the hemodynamic stability. In the 40 cases of epidural block under cesarean section, the initial stage of anesthesia, the input blood substitute blood stability compared with sodium lactate Ringer’s solution to observe the changes in blood pressure, heart rate between the two groups. 1 Materials and Methods 1.1 General Information: The whole group of 40 patients, aged 23 to 32 years, ASA Ⅰ ~ Ⅱ grade, no complications of pregnancy. Randomly divided into blood group (A group), lactated Ringer’s solution group (B group), two groups of 20 cases. 1.2 anesthesia and infusion methods: preoperative atropine 0.5mg, 0.1g phenobarbital intramuscular injection. Choose L2 ~ 3 gap puncture,
