A novel technique for one-lung ventilation in children with unilateral atelectasis
Research Square (Research Square)(2023)
摘要
Abstract It is very difficult to perform differential lung ventilation (DLV) in children with unilateral atelectasis, especially small children. We aimed to introduce a novel technique, one-lung ventilation with a single-lumen tube with a side hole (SH-SL-OLV), to perform DLV in this setting. This retrospective, observational, and analytic study enrolled 21 children with unilateral atelectasis admitted to the PICU. The children were treated with one-lung ventilation with a single-lumen tube (SL-OLV) or SH-SL-OLV.A total of 8 children underwent 45 SL-OLV sessions, and 13 children underwent 23 SH-SL-OLV sessions. Before treatment, no significant between-group difference was present in FiO 2 , P/F ratio, and PCO 2 . However, during OLV, FiO 2 and PCO 2 were significantly lower, while the P/F ratio and the duration hours of OLV were significantly higher in the SH-SL-OLV group than in the SL-OLV group. SH-SL-OLV is an innovative technique for the treatment of unilateral atelectasis in children. SH-SL-OLV can improve atelectasis and reduce the risk of hypoxemia and hypercapnia during OLV.
