Abstract

On 26 December 2003, at 05:26 hours, an earthquake of magnitude 6.6 (Richter scale) caused a disaster in the Bam region of Southeastern Iran, which had a population of approximately 102,000. In this study, the clinical and laboratory features and therapeutic interventions in pediatric (three months to 14 years) crush victims were analyzed. Determination of the type and amount of fluid therapy for prevention of acute renal failure (ARF) was the main aim of this study. Methods: The clinical and laboratory data and therapeutic interventions provided to 31 pediatric crush victims were collected. Early and vigorous fluid resuscitation was immediately performed. Resuscitation of the children from hypovolemic shock was initiated by interavenous (IV) administration of normal saline until the signs and symptoms of shock disappeared. For victims with crush injuries, an alkaline intravenous solution, up to 3 to 5 times more than maintenance doses was provided. In this study, there were two groups with decreasing severity of injury: (1) crush injury (CI), with or without ARF; and (2) non-crush injury (Non-CI). According to the above mentioned classification, there were 15 and 16 patients in group I and II, respectively. Results: The mean time spent under the rubble was 2.2 ±2.5 hours and 0.5 ±0.5 hours in Groups I and II, respectively.Seventy-five percent of ARF patients (n = 8), were admitted to the hospital the day of the earthquake (Day 0) and the day after earthquake (Day 1). In non-ARF patients (n = 7), 85.7% of the victims were admitted on Day 0 and Day 1. In Group II (ARF and non-ARF), all patients were admitted within three days after the earthquake. Although ARF did not develop in any of the children without CI, it was observed in eight of 15 patients with CI. There was no significant difference between CI with ARF (n = 8) and CI without ARF (n = 7) patients, in terms of the admission date, time of admission, hospitalization duration, and time under the rubble (TUR). Admission SGOTs were significantly different between these two groups. The ratio of the amount of delivered IV fluid (DL) to expected (EX) was based on weight of children was the only fluid therapy parameter in which there was a statistically significant difference between ARF and non-ARF groups. It was 3.6 ±0.99 in ARF and 4.8 ±0.74 in Nnon-ARF group (p = 0.01). Conclusions: Early intravenous volume replacement may prevent both ARF and dialysis need that may develop on the basis of rhabdomyolysis. In adults, six liters or 12–14 liters of fluids for prophylaxis of ARF in crush syndrome,were suggested. In children, it seems that DL/EX ratio (delivered to expected ratio) is the best marker for evolution of IV fluid therapy in pediatric patients. In children with crush injuries, DL/EX ratio of >4.8 was sufficient for the prevention of ARF
