ABSTRACT
Objective To evaluate the efficacy of Arndt endobronchial blocker (AEB) for airway management during one-lung ventilation (OLV) in pediatric patients.Methods Thirty pediatric patients,aged 4 months-12 yr,weighing 5.6-26.0 kg,of American Society of Anesthesiologists physical status Ⅱ-Ⅳ,scheduled for elective thoracotomy under OLV requiring the use of single lumen tracheal tube assisted by AEB,were enrolled in this study.OLV was performed with the AEB placed outside the single lumen tracheal tube in pediatric patients below 2 years old and with AEB inserted through the single lumen tracheal tube in pediatric patients ≥ 2 years old.The rate of successful establishment of artificial airway at first attempt,time of establishing artificial airway,time of pulmonary collapse,AEB malpositions and airway pressure before and after OLV were recorded,and the efficacy of lung collapse was evaluated.Results The rate of successful tracheal intubation of extraluminal and endoluminal AEB placement at first attempt was 100% in 30 pediatric patients,and no high airway pressure was found after OLV.The efficacy of lung collapse was poor in one patient and good in one patient,and intraoperative AEB malpositions were found in two patients among the pediatric patients used extraluminal AEB placement.The efficacy of lung collapse was good in one patient,intraoperative AEB malposition was found in one patient,and SpO2 was decreased after OLV in one patient among the pediatric patients used endoluminal AEB placement.Conclusion Reasonably selecting the method of placing AEB followed by enhancing intraoperative airway management can be safely and effectively applied for OLV in pediatric patients.
