외상성 뇌손상으로 감압 두개골 절개술을 시행 받는 환자에서 혈중 lactate 값과 사망률의 상관관계

초록

Background: The patients with traumatic brain injury showed ischemia due to increased intracranial pressure. This study evaluated the relationship of pre-anesthetic serum lactate level with in-hospital mortality. Methods: The archived medical records of 121 patients were retrospectively reviewed. Demographics and preoperative serum lactate level were analyzed. Results: Of the 121 patients, 32 patients expired in the hospital after decompressive craniectomy. Preoperative serum lactate levels were 3.2 ± 2.2 mmol/L in the survivors and 5.4 ± 3.0 mmol/L in the dead (P = 0.001), and the receiver operating characteristic curve revealed that a cut off value of 3.60 mmol/L was reasonable for predicting mortality. Conclusions: Preoperative serum lactate level is highly correlated with in-hospital mortality after decompressive craniectomy in traumatic brain injury.
