Effect of Perioperative Management on Outcome of Patients after Craniosynostosis Surgery.

Background: Craniosynostosis results from premature closure of one or more cranial sutures, leading to deformed calvaria and craniofacial skeleton at birth. Postoperative complications and outcome in intensive care unit (ICU) is related to surgical method and perioperative management. This study determined the perioperative risk factors, which affect outcome of patients after craniosynostosis surgery.

Methods: In a retrospective study, 178 patients with craniosynostosis who underwent primary cranial reconstruction were included. Postoperative complications following neurosurgical procedures including fever in ICU, level of consciousness, re-intubation, and blood, urine, and other cultures were also performed and their association with the main outcomes (length of ICU stay) were analyzed.

Results: Factors independently associated with a longer pediatric ICU stay were fever (OR=1.59, 95% CI=1.25-4.32; =0.001), perioperative bleeding (OR=2.25, 95% CI=1.65-3.65; =0.01), age (having surgery after the first 5 years) (OR=1.59, 95% CI=1.33-3.54, =0.016) and infection (OR=2.17, 95% CI=1.83-7.46; =0.002). Mean blood loss during surgery was significantly higher in patients whose duration of ICU was longer than 4 days compare to less than 4 day (=0.026). Amount of bleeding significantly was correlated to duration of surgery (r=0.70, =0.001) and patient's age (r=0.23, =0.44).

Conclusion: perioperative management particularly blood loss could deteriorate patients outcome and length of stay in ICU and hospital. Infections in ICU could deteriorate outcomes.
