Abstract: Objective To compare the effect of Arndt endobronchial blocker and double-lumen tube on one lung ventilation in children undergoing thoracic surgery.Methods Fourty children undergoing thoracic surgery were divided into Arndt endobronchial blocker group(Group A,n=20) and double -lumen tube group (Group D,n=20) randomly. Anesthetic management and lung isolation were performed according to a standardized protocol.The changes of MAP,HR,PetCO2 and Paw were recorded at the following time point,intubation tube before(T1),intubation tube(T2),double lung ventilation(T3),one lung ventilation(T4).The intubation time,lung collapse time,one lung ventilation time,hypoxemia duration of surgery and adverse event and others were recorded. Results Arndt endobronchial blocker group compare with double-lumen tube group,the Paw and PetCO2 were lower at the time of one lung ventilation (P<0.05); the intubation time was shorter (P<0.05); the time of lung collapse was longer (P<0.05); and the lung collapse score was higher (P<0.05). Conclusion Compared with inserting double-lumen tube blind, Arndt endobronchial blocker inserted by fiber bronchoscope can provide better one lung ventilation in children undergoing thoracic surgery.
