Evaluation of the premature infant at risk for postoperative complications

Can J Anaesth. 1987 Nov;34(6):627-31. doi: 10.1007/BF03010525.


We reviewed anaesthetic records of 35 infants with a history of prematurity, who presented for elective herniorrhaphy. We applied a scoring system to help evaluate risk of postoperative complications. Six patients experienced postoperative complications. All six patients had a score of five or more and gave history of either apnoea or a history of moderate bronchopulmonary dysplasia. A preoperative history of apnoea and/or moderate bronchopulmonary dysplasia appear to be valuable markers for postoperative complications. A conceptual age of 40 weeks is an acceptable lower limit of age providing there is no history of apnoea or pulmonary disease.
