Awake Prone Positioning in an Infant Following Living Donor Liver Transplantation

Background: Prone position has been proven to improve ventilation and oxygenation in infants. Currently, there are few reports of early prone position ventilation after pediatric liver transplantation. Here, we present our experience with prone position in an infant following living donor liver transplantation, in an attempt to improve oxygenation.

Case Presentation: An 8-month-old boy, 7.5 kg, experienced two failed extubations that presented with Type II respiratory failure due to dyspnea, potentially caused by consolidation and airway secretions. To prevent the third failure of extubation, prone position ventilation was implemented after the third extubation on the 11th postoperative day. Oxygenation increased after each prone position session with no signs of transplant liver ischemia or other adverse outcomes. Following two days of continuous prone position, airway secretions decreased, and the infant was discharged from the ICU. The third extubation procedure was successful.

Conclusions: Prone position ventilation may be effective in this infant without adverse events, indicating that early prone position is not absolutely contraindicated after pediatric liver transplantation. Therefore, more reasonable prone position strategies should be sought in infants undergoing liver transplantation.
