Safety and efficacy of using bronchial occluder in patients undergoing thoracoscopy pulmonary bulla surgery

Abstract

Objective The purpose of this study was to compare the safety and efficacy of using bronchial blockers tube(BB) versus double cavity bronchial catheter in thoracoscopy pulmonary bulla surgery. Methods Eighty patients with pulmonary bulla. were randomly divided into two groups(n=40): group A received a double cavity bronchial tube, group B received the bronchial occluder. The general information, intubation success rate, blood gas analysis at different time points immediately after anesthesia(T0), 20 min after one-lung ventilation(T1), 60 min after one-lung ventilation(T2) and 60 min after two-lung ventilation(T3) and the occurrence of adverse reactions were recorded. Results Compared with group A, the intubation success rate of group B was higher(P 0.05). In contrast with T0 and T3, airway plateau pressure(Pplat) and peak airway pressure(Ppeak) of the above groups were dramatically increased at T1 and T2(P<0.05). Besides, Pplat and Ppeak from group B were lower than those from group A(P<0.05). After extubation, 11 patients from group A had a hoarseness and sore throat, the incidence rate was 27.5%; In group B(3 cases), rate of the same adverse reactions was 7.5%. The occurrence rates of adverse effect after extubation were statistically significant between the two groups(P<0.05). Conclusions In contrast with double lumen catheter, applying bronchial occluder in thoracoscopy pulmonary bulla surgery is a more effective and safer way to reduce blood gas changes during operation and postoperative discomfort.
