Retrospective Survey and Analysis of Anaesthesia and Outcomes in Paediatric Cleft Lip or Palate Surgery in a Tertiary Care Center, Portugal.

INTRODUCTION: Orofacial clefts are the most common craniofacial abnormalities, affecting approximately one in 700 newborns each year. The anaesthetic management of these patients is challenging, including difficulties in airway approach and respiratory complications that have direct implications in the final outcome.

AIM: The present study aimed to characterize the anesthetic approach to paediatric patients undergoing cleft palate or lip surgical repair and review the perioperative anesthetic complications in a tertiary Portuguese hospital.

METHODS: Data were collected from a retrospective review of the patient records which included anaesthesia perioperative notes of paediatric patients submitted to cleft surgery repair during a five-year period (2016 to 2021). Demographic, pre-anaesthetic characteristics, anaesthetic management and perioperative complications were recorded.

RESULTS: A total of 102 patients were included, with a median age of 1.5 years. Congenital syndromes were present in 14 (13.7%) of the children included. Inhalational induction of anaesthesia with sevoflurane was the preferred approach in 86 cases (84.3%), with neuromuscular blockade being used in 59 cases (57.8%). Intubation was achieved at first attempt in 91 (89.2%) cases with four (3.9%) patients needing three or more attempts. Intraoperative respiratory-related complications were the most frequent, occurring in 22 (21.6%) cases. These include multiple attempts to intubation, desaturation due to bronchospasm or laryngospasm. The average length of stay was two days. Postoperative complications were recorded in 17 (16.7%) of patients.

DISCUSSION: The predominance of airway and respiratory complications occurring in cleft is consistent with previous studies. Care must be taken in order to avoid such complications in the perioperative period by following protocols, having skilled personnel, appropriate monitoring equipment and airway devices available during cleft surgeries to minimise morbidity.
