Factors Influencing Prolonged Intensive Care Unit Length of Stay after Craniotomy for Intracranial Tumor in Children: A 10-year Analysis from A University Hospital

Background: Postoperative intensive care unit (ICU) admission is routinely practiced in pediatric and adult craniotomy. This study aims to identify the factors associated with an ICU stay of more than one day (prolonged ICU stay, PIS) after pediatric brain tumor surgery.Methods: Medical records of children who underwent craniotomy for brain tumor during a 10-year period were reviewed and analyzed. Perioperative variables were examined and compared between the one-day ICU stay (ODIS) and PIS groups.Results: A total of 314 craniotomies performed on 302 patients were included. Patients requiring postoperative ICU care for more than a day represented 37.9% of the sample. Significant factors found in the multivariate analysis affecting prolonged ICU length of stay included operative time >= 360 minutes (adjusted odds ratio [AOR], 2.438; 95% confidence interval [CI]: 1.223-4.861; p = 0.011), presence of an endotracheal (ET) tube (AOR, 7.469; 95% CI: 3.779-14.762;p < 0.001), and external ventricular drain (EVD) at ICU admission (AOR, 2.512; 95% CI: 1.458-4.330; p = 0.001).Conclusion: While most children undergoing a craniotomy for brain tumor need a postoperative ICU care of <= 1 day, slightly more than a one-third in our study stayed longer. The prediction of a PIS can be beneficial for optimal resource utilization, increasing ICU bed turnover rate, reduction of operation cancellation, and improved preparation for parent expectations.
