摘 要:[摘要] 目的 探讨膈神经冷冻用于肺叶切除手术的效果和对机体的影响。研究在-65 ℃条件下,不同冷冻时间的治疗效果,确定最佳冷冻时间。方法 选择择期行肺叶切除患者50例,按随机数字表法,随机分为5组:对照组、膈神经冷冻30、60、90、120 s组。记录患者术后的心率、血压、血氧饱和度、呼吸频率、胸腔引流量、拔管时间,并进行肩胛区牵涉视觉模拟痛评分(VAS)。拔除胸腔引流管后,常规行胸部正侧位X线片及胸部B型超声检查,观察各组术后残腔情况,术后90 d进行胸部透视,观察患侧膈肌运动情况。结果 冷冻30、60、90、120 s组胸液引流量[第1天分别为(329±178)、(345±150)、(268±51)、(227±36)ml,第2天分别为(251±131)、(269±112)、(208±61)、(158±110)ml]、拔管时间[分别为(5.8±1.75)、(4.6±1.77)、(3.9±0.74)、(3.6±1.07)d]及VAS[分别为(3.6±2.9)、(2.2±2.4)、(1.0±1.3)、(0.7±1.2)分]明显小于对照组[分别为(375±136)ml、(309±132)ml、(5.7±2.36)d、(4.0±3.3)分]。90 s及120 s冷冻组各指标明显低于30 s及60 s冷冻组。90 s冷冻组与120 s冷冻组均差异无统计学意义(均P>0.05)。各组患者的心率、血压、血氧饱和度、呼吸频率差异均无统计学意义(均P>0.05)。对照组术后残腔较大(>200 ml),积液较多(>200 ml),1例行穿刺抽取,各冷冻组术后残腔较小(<100 ml),无需处理。术后3个月,各组膈肌运动情况良好,无反常运动。结论 膈神经冷冻用于肺叶切除手术能有效减少术后胸腔引流量、减少术后残腔形成且拔管时间缩短,肩胛区牵涉痛明显减轻,最佳冷冻时间为90 s,膈神经冷冻术对循环和呼吸功能无明显影响,值得临床进一步研究、应用和推广。[Abstract] Objective To investigate the results and effects of freezing phrenic nerves for the patients of pulmonary lobectomy. To optimize the best freezing time by studying the effects of different time at -65 ℃. Methods 50 patients of pulmonary lobectomy were randomly entered into 5 groups, including control group, 30 seconds group, 60 seconds group, 90 seconds group, 120 seconds group. After operation, the patients' cardiotach, blood pressure, SaO2, breath rate, time period of pulling out drainage tube and VAS about referred pain of scapular region were noted. After pulling out the intrathoracic drain tube, the routine chest normal X ray film and chest ultrasonic inspection were processed and the post-operation remnant cavity were observed. The chest normal fluoroscopy was inspected in 90 days after operation in order to observe the motion information of trouble side diaphragmatic muscle. Results The chest fluid [first day (329±178) ml, (345±150) ml, (268±51) ml, (227±36) ml, second day (251±131) ml, (269±112) ml, (208±61) ml, (158±110) ml, time of pulling out intrathoracic drain tube (5.8±1.75) days, (4.6±1.77) days, (3.9±0.74) days, (3.6±1.07) days] and VAS [(3.6±2.9) scores, (2.2±2.4) scores, (1.0±1.3) scores, (0.7±1.2) scores] about referred pain of scapular region of freezing groups were obviously lower than those in the control group [(375±136) ml, (309±132) ml, (5.7±2.36) days, (4.0±3.3) scores]. 90 s and 120 s freezing groups were lower than that of 30 s and 60 s groups, and the 90 s freezing group did not significantly different from the 120 s group. The heart rate, blood pressure, saturation of blood oxygen and breathing rate of each group also had no difference. The remnant cavity sizes were larger in the control group (〉200 ml), they also had more fluidity (〉200 ml), and one case had been taken punctuation. The remnant cavity sizes of freezing groups were small and didn't need spec
