Abstract:
Objective To evaluate the value of Univent tube in the airway management during one-lung ventilation. Methods A total of 40 patients with pneumothorax undergoing video-assisted thoracoscopic surgery (VATS) were randomly divided into Univent (U) and double-lumen tube (Robertshaw) (D) groups (20 in each). In U group, intubation was performed under the guidance of a fibreoptic bronchoscope; while in D group, the position of the tube was confirmed using fibreoptic bronchoscopy after intubation. The time of intubation, number of secondary dislodgements, quality of lung deflation, peak airway pressure during one-lung ventilation, and blood artery gas analysis data in the two groups were recorded 30 minutes after one-lung ventilation. Results The intubation time in U group was significantly longer than that in D group [(6.18?1.26) min vs (3.26?0.82) min, t=8.654, P=0.000]. The number of secondary dislodgements was 7 in U group, and 5 in D group(U=187.500, P=0.663). No significant difference was detected in the quality of lung deflation between the two groups, (U group: 15 excellent, 3 fair, and 2 poor; D group: 17 excellent, 2 fair, and 1 poor;U=179.500, P=0.583). The peak airway pressure during one-lung ventilation in U group was significantly lower than that in D group [(15.3?3.5) cm H2O vs (21.4?6.6) cm H2O, t=-3.649, P=0.001]; and the oxygen pressure in group U was significantly higher than that in group D [(303.8?65.7) mm Hg vs (258.4?72.9) mm Hg, t=2.066, P=0.046]. No significant difference was found in carbon dioxide pressure and oxygen saturation between the two groups. Conclusion During VATS, univent tube showed the same effectiveness and safety as DLT for one-lung ventilation.
