Abstract

AşıLıOğLU, Nazik; TURNA, Fatih  and  PAKSU, Muhammet Şükrü. Admission hyperglycemia is a reliable outcome predictor in children with severe traumatic brain injury. J. Pediatr. (Rio J.) [online]. 2011, vol.87, n.4, pp. 325-328. ISSN 0021-7557.  http://dx.doi.org/10.1590/S0021-75572011000400009.

OBJECTIVE: To identify the relationship between admission hyperglycemia and outcome in children with severe brain injury at hospital discharge and 6 months later. METHOD: A retrospective analysis of blood glucose levels was conducted in 61 children with severe brain injury admitted to the Pediatric Intensive Care Unit between November 1, 2005 and October 30, 2009. Hyperglycemia was considered for a cut off value of > 150 mg/dL, based on literature. Outcome was measured with the Glasgow Outcome Scale at hospital discharge and 6 months after discharge. Death was also analyzed as an outcome measure. RESULTS: Mean admission blood glucose of the patients was 251 mg/dL (68-791). Hyperglycemia was noted on admission in 51 (83.6%) patients. A moderately significant positive correlation was found between admission blood glucose and severity of head trauma according to Abbreviated Injury Score (r = 0.46). Mean admission glucose level of non-survivors was significantly higher (207 mg/dL vs. 455 mg/dL, p < 0.001). Mean blood glucose level of the patients in bad outcome group was found significantly higher compared to that of the patients in good outcome group at hospital discharge and 6 months after discharge (185 mg/dL vs. 262 mg/dL, p < 0.15 and 184 mg/dL vs. 346 mg/dL, p < 0.04, respectively). CONCLUSIONS: Hyperglycemia could be considered as a marker of brain injury and, when present upon admission, could reflect extensive brain damage, frequently associated with mortality and bad outcome. Further studies are needed to investigate the effect of strict glycemic control on mortality and outcomes.
