目的:探讨七氟烷对心脏瓣膜病患者体外循环( CPB)后肺损伤的保护作用。方法选择体外循环心脏瓣膜病变患者40例,随机分为对照组(C组,10例)和七氟烷吸入组(S组,30例),对照组采用静脉麻醉,不使用任何吸入麻醉药,七氟烷吸入组分为S1、S2、S3三个亚组,每组10例,体外循环后分别吸入0.5、1.0、1.5 MAC的七氟烷维持麻醉。四组病人术前用药、麻醉诱导、体外循环前和体外循环过程中麻醉维持、体外循环方法均相同,分别于麻醉诱导前(T0)、体外循环前(T1)、停机(T2)、手术结束(T3)、术后2 h (T4)、术后4 h (T5)、术后8 h (T6)、术后12 h (T7)、术后24 h (T8)测量患者动脉氧分压( PaO2)、动脉二氧化碳分压(PaCO2)、潮气量(VT)、气道压、吸入氧浓度(FiO2),计算患者肺泡动脉氧分压差(A-aDO2)、氧合指数(OI)、肺动态顺应性(Cdyn)、肺静态顺应性(Cstat),观察肺氧合与肺顺应性变化。结果与 C 组比较,S1、S2、S3组肺氧合功能好转(P<0.05),顺应性上升(P<0.05)。结论七氟烷麻醉能减轻体外循环导致的肺损伤,并和七氟烷的吸入量成正相关。
目的:探討七氟烷對心髒瓣膜病患者體外循環( CPB)後肺損傷的保護作用。方法選擇體外循環心髒瓣膜病變患者40例,隨機分為對照組(C組,10例)和七氟烷吸入組(S組,30例),對照組採用靜脈痳醉,不使用任何吸入痳醉藥,七氟烷吸入組分為S1、S2、S3三箇亞組,每組10例,體外循環後分彆吸入0.5、1.0、1.5 MAC的七氟烷維持痳醉。四組病人術前用藥、痳醉誘導、體外循環前和體外循環過程中痳醉維持、體外循環方法均相同,分彆于痳醉誘導前(T0)、體外循環前(T1)、停機(T2)、手術結束(T3)、術後2 h (T4)、術後4 h (T5)、術後8 h (T6)、術後12 h (T7)、術後24 h (T8)測量患者動脈氧分壓( PaO2)、動脈二氧化碳分壓(PaCO2)、潮氣量(VT)、氣道壓、吸入氧濃度(FiO2),計算患者肺泡動脈氧分壓差(A-aDO2)、氧閤指數(OI)、肺動態順應性(Cdyn)、肺靜態順應性(Cstat),觀察肺氧閤與肺順應性變化。結果與 C 組比較,S1、S2、S3組肺氧閤功能好轉(P<0.05),順應性上升(P<0.05)。結論七氟烷痳醉能減輕體外循環導緻的肺損傷,併和七氟烷的吸入量成正相關。

Objective To investigate the protective effects of sevoflurane on pulmonary injury in patients suffered valvulopathy after cardiopulmonary bypass(CPB). Methods Forty patients were randomly divided into four groups:control group(group C), evolfurane group(group S1, group S2, group S3). The patients of group C were only treated with intravenous anesthetics; 0.5MAC, 1.0MAC, 1.5MAC sevoflurane were inhalated in group S1,S2,S3 after CPB. Patients in all groups were the same in premedication, anesthetic induction, maintenance of anesthesia before and during CPB, method of cardiopulmonary bypass. PaO2, PaCO2, VT, FiO2, A-aDO2, OI ,Cdyn, Cstat were measured before induction of anesthesia (T0) , before CPB(T1), at the discontinuation of CPB(T2), at the end of operation(T3), 2 h(T4), 4 h(T5), 8 h(T6), 12 h(T7), 24 h(T8) after operation. Results Compared with group C, the pulmonary oxygenation function of patients in group S1,S2,S3 was better respectively after operation(P<0.05);the compliance of pulmonary was raised respectively(P<0.05). Conclusion Sevolfurane inhalated anesthesia can reduce lung injury in patients after cardiopulmonary bypass, and its lung protection is related to the amount of sevolfurane positively.
