Summary
A 4-year-old boy experienced severe water intoxication during knee arthroscopy, leading to a critical drop in sodium levels. Prevention strategies include using saline irrigation and tourniquets to avoid hypoosmolar fluid absorption.
Area of Science:
- Pediatric Surgery
- Anesthesiology
- Nephrology
Background:
- Water intoxication is a rare but serious complication during arthroscopic procedures.
- Hypoosmolar irrigation fluids can lead to significant electrolyte disturbances in pediatric patients.
Observation:
- A 4-year-old boy developed massive water intoxication following knee arthroscopy.
- Postoperative sodium plasma concentration decreased to 100 mmol/l.
Findings:
- Prolonged surgery, high intra-articular pressure, capsular tears, and low body weight may trigger this complication.
- Using a tourniquet and 0.9% NaCl irrigation fluid can prevent excessive hypoosmolar fluid incorporation.
Implications:
- Highlights the importance of careful fluid management during pediatric arthroscopy.
- Suggests specific preventive measures to mitigate the risk of hyponatremia.
- Emphasizes the need to adhere to guidelines for correcting hyponatremia, matching correction time to development time.
