Continuous renal replacement therapy for acute kidney injury: a case report.

Abstract

Background: Acute kidney injury is a severe complication of pediatric trauma with complex and diverse mechanisms and is associated with multiple organ dysfunction. For severely injured children, renal function should be closely monitored, and continuous renal replacement therapy should be promptly initiated if there is a risk of developing severe acute kidney injury. This case report describes the treatment process of a child with acute kidney injury due to trauma, highlighting the need to improve the rapid identification of traumatic acute kidney injury risk and actively implement resuscitation strategies to protect renal function in trauma patients.

Case description: A 3-year-old boy presented with acute kidney injury following a car accident. Multi-organ dysfunction developed, and laparotomy and liver laceration repair were performed. Continuous renal replacement therapy for 7 days, plasma exchange, antimicrobial therapy, and multi-organ support were provided. A 1-year follow-up showed no organ dysfunction.

Conclusions: This case report describes the treatment process of a child with acute kidney injury due to trauma, highlighting the need to improve the rapid identification of traumatic acute kidney injury risk and actively implement resuscitation strategies to protect renal function in patients with trauma. Prompt continuous renal replacement therapy should be considered when necessary to prevent adverse outcomes.
