Inquest into the death of Manusiu Amone

0y · Female·ischaemic hypoxic encephalopathy secondary to factors associated with the sudden onset of gasping respirations with difficulty in ventilating, caused by persistent pulmonary hypertension of the newborn

Manusiu Amone died from ischaemic hypoxic encephalopathy secondary to persistent pulmonary hypertension of the newborn (PPHN), not from pethidine toxicity as initially suspected. At 145 minutes of life, she developed gasping respirations and failed to respond to resuscitation. Key clinical lessons: (1) pethidine administration at 9:25pm, approximately 35 minutes before delivery, was unwise given advanced labour progression—alternative analgesia (nitrous oxide, reduced syntocinon) should have been considered; (2) the 150mg dose was excessive and based on guesswork rather than validated dosing methodology; (3) forensic pathologists' initial interpretation of autopsy findings (particularly squames in lungs) required specialist perinatal pathology input; (4) the case highlights systemic deficiencies in perinatal postmortem investigation protocols. The excessive squames, raised nucleated red cell count, and unresponsiveness to ventilation pointed to intrauterine hypoxia and primary lung pathology. Clinical staff appropriately managed resuscitation; staffing shortages and call alarm delays were secondary to the underlying pathology.
