7y · Female·cardiac tamponade due to total parenteral nutrition fluid leakage into the pericardial sac as a result of central venous line therapy

A 7-year-old girl with spina bifida died from cardiac tamponade caused by total parenteral nutrition (TPN) fluid leaking into the pericardial sac via a central venous line inserted during bowel obstruction surgery. Clinical lessons: cardiac tamponade is a rare but life-threatening complication of central lines presenting with deceptively non-specific signs (tachycardia, unobtainable blood pressure, cool peripheries, pale appearance). The patient remained alert and communicative until sudden collapse, masking severity. Critical delays occurred: pager malfunction prevented timely senior doctor notification; nursing staff did not recognise critical illness warrant emergency response team activation; no doctor considered tamponade in differential diagnosis due to rarity and lack of exposure. Earlier recognition of the triad of unobtainable BP, faint pulses, and cool peripheries—especially after 12:25 AM—might have prompted urgent imaging (echocardiogram) and cardiology consultation. Enhanced training on central line complications, awareness of decompensation patterns, and lower threshold for emergency escalation when vital signs cannot be obtained would improve outcomes.
