Effect of Resuscitation on Gastric Emptying Using POCUS in Pediatric Trauma Patients

Inclusion Criteria: * Pediatric patients aged 2 to 7 years presenting with trauma. * Presenting with hemorrhagic shock requiring hemodynamic resuscitation (diagnosed according to Advanced Paediatric Life Support \[APLS\] guidelines based on clinical and laboratory evidence of inadequate tissue perfusion secondary to acute blood loss, such as age-adjusted hypotension, tachycardia, prolonged capillary refill time \> 2 seconds, weak peripheral pulses, altered mental status, elevated serum lactate, and/or increased base deficit). * Hemodynamically stable enough to undergo point-of-care gastric ultrasound (POCUS) examination without delaying emergency medical management. Exclusion Criteria: * Known gastrointestinal diseases affecting gastric motility (e.g., gastric outlet obstruction, intestinal obstruction). * History of prior upper gastrointestinal surgery. * Significant abdominal injury that may affect gastric motility. * Need for immediate emergency surgical intervention before completion of study baseline assessments. * Inability to adequately perform gastric POCUS (e.g., extensive abdominal wounds, surgical emphysema, or poor acoustic window). * Gastric decompression performed before the initial ultrasound assessment. * Isolated head injury.
