Application of laryngeal mask airway anesthesia with preserved spontaneous breathing in children undergoing video-assisted thoracic surgery

PurposeTo investigate the feasibility and safety of non-intubated general anesthesia with spontaneous breathing combined with paravertebral nerve blocks (PVNB) in young children undergoing video-assisted thoracic surgery (VATS) and to determine its significance for rapid recovery after pediatric thoracic surgery.MethodsThe data of 46 children aged 6–36 months with an American Society of Anesthesiologists status of I–II who underwent elective VATS under general anesthesia were retrospectively analyzed. Of these patients, 25 underwent non-intubated general anesthesia with spontaneous breathing combined with PVNB (non-intubation group), and 21 received conventional intubated general anesthesia combined with local infiltration anesthesia (intubation group). The following perioperative parameters were compared between the two groups: heart rate (HR), mean arterial pressure, saturation of pulse oximetry (SpO2), partial pressure end-tidal carbon dioxide, time from the completion of the operation to extubation or removing laryngeal masks, time to first feeding after the operation, length of postoperative in-hospital stay, incidence of postoperative complications, and hospitalization expenses.ResultsThe operations were completed successfully in both groups. When the non-intubation group was compared with the intubation group, the minimal SpO2 level during the surgery was higher (93% vs. 88%, P
