可视双腔支气管导管与普通双腔支气管导管在胸外科手术中的应用效果比较

Efficacy of visual dual lumen bronchial catheter versus conventional dual lumen bronchial catheter in thoracic surgery

目的比较可视双腔支气管导管与普通双腔支气管导管用于胸外科手术麻醉的效果。方法选取西双版纳傣族自治州人民医院2021年6月至2023年6月择期行胸外科手术需要肺隔离的患者80例进行随机对照研究,采用随机数字表法分为观察组、对照组各40例。观察组采用可视双腔支气管导管,对照组采用普通双腔支气管导管。观察两组插管定位时间、术中导管移位数、重新定位时间、插管时生命体征和并发症发生情况。结果观察组在插管定位准确时点平均动脉压[(71.92±8.33)mmHg](1 mmHg=0.133 kPa)、心率[(62.37±12.14)次/min]均低于对照组[(95.27±9.51)mmHg,(88.42±15.08)次/min],指氧饱和度[(99.01±0.32)%]高于对照组[(96.67±1.65)%](t=12.56、15.41、8.54,均P<0.05)。观察组插管定位时间[(22.54±7.11)s]、术中导管移位后重新定位时间[(16.22±12.14)s]均短于对照组的(74.29±12.52)s、(32.74±11.48)s(t=1.14、5.17,均P<0.05)。观察组术后肺部感染发生率为0,低于对照组的10.0%(4/40)(χ^(2)=6.49,P<0.05)。结论可视双腔支气管导管用于胸外科手术麻醉插管中对患者生命体征影响小,插管定位时间及重新定位时间短,肺部感染并发症更少。

Objective To investigate the anesthetic effects of visual dual lumen bronchial catheter versus conventional dual lumen bronchial catheter in thoracic surgery.Methods A total of 80 patients who underwent elective thoracic surgery requiring lung isolation at the People's Hospital of Xishuangbanna Dai Autonomous Prefecture from June 2021 to June 2023 were selected for a randomized controlled study.The patients were divided into an observation group and a control group,with 40 patients in each group,using the random number table method.The observation group used a visual dual lumen bronchial catheter,while the control group used a conventional dual lumen bronchial catheter.The two groups were compared regarding positioning time for intubation,number of cases with catheter displacement,repositioning time,vital signs during intubation,and the occurrence of complications.Results In the observation group,the average arterial pressure at the time of accurate intubation positioning was(71.92±8.33)mmHg(1 mmHg=0.133 kPa),and the heart rate was(62.37±12.14)beats/min.These values were significantly lower than those in the control group[(95.27±9.51)mmHg,(88.42±15.08)beats/min,t=12.56,15.41,both P<0.05].Additionally,the oxygen saturation in the observation group was significantly higher than that in the control group[(99.01±0.32)%vs.(96.67±1.65)%,t=8.54,P<0.05].In the observation group,the positioning time for intubation and the repositioning time after catheter displacement during surgery were(22.54±7.11)seconds and(16.22±12.14)seconds,respectively.These durations were significantly shorter than those in the control group[(74.29±12.52)seconds,(32.74±11.48)seconds,t=1.14,5.17,both P<0.05].The incidence of postoperative pulmonary infections in the observation group was significantly lower than that in the control group[0 vs.10.0%(4/40),χ^(2)=6.49,P<0.05].Conclusion The use of a visual dual-lumen bronchial catheter for anesthesia intubation in thoracic surgery has a minimal impact on patients'vital signs,along with shorter intubation positioning and repositioning durations,and a lower incidence of pulmonary infection complications compared with the conventional dual-lumen bronchial catheter.
