Methods: We retrospectively reviewed medical records of children age 6 - 19 years old who underwent thoracic surgery from June 2003 to 2008. Preoperative risk factors extracted include (age, gender and cardiothoracic anomalies), nutritional status, past medical history. Laboratory data include complete blood count, 2D echocardiogram, chest radiograph, pulmonary function tests and blood gas analysis.
Results: A total of 506 children, of which 330 (65.2%) developed post-operative complications while 176 (34.8%) with none. Atelactasis (25.6%) was the top complications. Among the clinical variables analyzed, only three variables were independently predictive of post-operative complication namely; C of < 80 (p=.030); blood pH of < 7.35 (p=.024) and white blood cell count of > 12 T per cubic mm (p=.0001. ROC analysis derived the best minimum cut-off score of 11 points with a sensitivity of 88.8% and specificity of 85.1% LR+ of 5.41. The overall accuracy of the scoring index 81.6% [p=.002].
Conclusion: Pre-operative risk stratification using this scoring index is simple and rapid.
To determine the accuracy of a simple pre-operative scoring system to predict post-operative complications among children undergoing cardiothoracic surgery.
