Abstract:
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), χ2 = 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.
