压力控制通气模式对全麻腹腔镜下食管裂孔疝修补术中血液循环影响的研究

Influence on circulation witlo pressure controcled ventilation during the operation of the repair of hiatal hernia with laproscopil surgery in general anesthesia

目的探讨压力控制模式(PCV)对全麻腹腔镜下食管裂孔疝修补术的患者术中循环的影响。方法前瞻性分析2012年2月至2015年10月,新疆自治区人民医院45例在全麻下进行腹腔镜下食管裂孔疝修补术患者的病案资料,其中压力控制通气模式23例,容量控制通气模式(VCV)22例,对比2组患者术中平均动脉压、中心静脉压、心率、血氧饱和度。结果 VCV组术中平均动脉压、中心静脉压、心率均高于PCV组(t=2.57、3.51、3.77,P=0.018、0.001、0.002),差异有统计学意义;VCV组与PCV组在术中血氧饱和度的比较中差异无统计学意义,(t=0.68,P=0.505)。结论压力控制通气模式对腹腔镜下食管裂孔疝修补术患者术中的血液循环影响较小,较为安全。

Objective To investigate the influence on circulation steady of the patient with pressure controlled ventilation during the repair of hiatal hernia with laparoscopic surgery in general anesthesia. Methods The totle of 45 cases are diveded into two groups （PCV pressure controlled ventilation and VCV volume controlled ventilation） with laparoscopic surgery in general anesthesia,22 cases for VCV and 23 cases for PCV, which is analyzed prospectively at people, hospital Xin Jiang province from 2013 to 2015. The comparison of mean arterial pressure MAP, central venious pressure CVP, heart rate and oxyhemoglobin saturationgen is between two groups. Results The MAP、 HR、 CVP of patients in VCV group is higher than that of PCV group （ Z = 2. 57、 3. 51、 3. 7 7, Z3 = 0. 018、 0. 001、 0. 002 ） , and the difference has statistically significent. The Sp02 in this two groups has no difference （ t = 0. 68 , P = 0. 505 ） . Conclusion PCV is a better ventilation due to steady circulation for patients in the repair of hiatal hernia with laparoscopic surgery.
