Objective:
To describe the pediatric intensive care unit (PICU) course and resource utilization for children with brain tumor resection and to identify factors predicting prolonged (>1 day) PICU length of stay. After craniotomy for brain tumor resection, children recover in the PICU. A few require critical care interventions and a >24-hr length of stay.
Design:
We reviewed all brain tumor resection patients admitted to the PICU over 2 yrs. Preoperative, intraoperative, and postoperative variables and tumor characteristics were examined. The extracted variables were compared between two groups with a length of stay in the PICU of >1 or <1 day.
Setting:
Pediatric intensive care unit in a tertiary academic children's medical center.
Patients:
A total of 105 patients post brain tumor resection were admitted to the PICU over the study period and analyzed.
Interventions:
Record review.
Measurements And Main Results:
Thirty-two (31%) of 105 patients remained in the PICU for >1 day. The mean age of patients in the >1 day group was 5.0 ± 0.81 yrs and 8.78 ± 0.65 yrs in the <1 day group (p < .05). The estimated blood loss was 20 ± 2.37 mL/kg in the >1 day and 9 ± 0.92 mL/kg in the <1 day group (p < .05). Fifteen (14.3%) patients were mechanically ventilated on arrival in the PICU; these patients more often had a length of stay of >1 day (p < .05). The number of unexpected intensive care unit interventions were 0.7 per patient, were more common in the >1 day group, and included treatment of sodium abnormalities, new neurologic deficits, paresis, or seizures (p < .05). In a logistic regression model, estimated blood loss and intubation on arrival predicted longer lengths of stay in the PICU (odds ratio, 1.1; 95% confidence interval, 1.05-1.18; and odds ratio, 33; 95% confidence interval, 2.57-333, respectively), with a receiver operating characteristic curve of 0.86 and 95% confidence interval, 0.78-0.94.
Conclusions:
Large intraoperative estimated blood loss and intubation on arrival may be predictive of PICU lengths of stay of >1 day for children who have had a craniotomy for brain tumor resection. Intensive care unit interventions are more common in these children.
