چکیده

abstract   objective: to evaluate the association of base deficit (bd) with mortality in traumatized children, and to assess this association in a subgroup of patients with traumatic brain injury (tbi).   methods: in this cross-sectional study performed prospectively on a convenience sample of patients under 16 years of age with trauma presenting to an academic level іі trauma center, we obtained venous bd values initially and followed the patients for in-hospital mortality. initial vital signs were measured and injury severity score (iss), randomized trauma score (rts), and pediatric trauma score (pts) were calculated.   results: a total of 102 patients were included, with 48 patients diagnosed with tbi. nine patients (8.8%) died during admission, of which 6 were diagnosed with tbi. based on the univariate analysis, bd was associated with mortality in the whole group (p = 0.01), but not in the tbi subgroup (p = 0.08). in multivariable analysis, rts was the only variable independently associated with mortality (p = 0.001, odds ratio [or] = 0.197). linear regression model showed that bd was predictive of iss, rts, and pts. receiver operating characteristics (roc) curve showed a cutoff point of -7 mmol/l for bd, below which there is a 12 fold increased risk for mortality.   conclusion: bd is a useful parameter in mortality prediction in pediatric trauma like in adult age group, but this predictive role in tbi patients is not supported by our results.

Base deficit correlates with mortality in pediatric abusive head trauma.

BACKGROUND/PURPOSE Children suffering from abusive head trauma (AHT) have worse outcomes compared to non-AHT, but the reasons for this are unclear. We hypothesized that delayed medical care associated with AHT causes prolonged pre-hospital hypotension and hypoxia as measured by admission base deficit (BD), and that this would correlate with outcome. METHODS We performed a 10-year retrospectiv...

Pre-hospital time intervals in trauma patient transportation by emergency medical service: association with the first 24-hour mortality

Objective: Most previous retrospective studies failed to show a consistent association between pre-hospital time intervals and mortality in trauma patients, bringing the recommendation of “transport fast to increase survival” under question. The aim of this study was to evaluate the association of response time, scene time, and transport time with 24-hour in-hospital mortality....

Association between Red Cell Distribution Width and Mortality in Pediatric Patients Admitted to Intensive Care Units

Background: Red cell distribution width (RDW) is a routine laboratory measure that could be used as a predictor of mortality in critically ill patients. Identification of patients at risk for mortality early in the course of PICU admission is an important step in improving the outcome. We aimed to assess the use of RDW as an early biomarker for outcome in pediatric critical illnesses. Methods:...
