High-Yield Clinical Pearls
Infant botulism classically begins with constipation, followed by poor feeding, weak cry, ptosis, and descending flaccid paralysis with absent reflexes. Honey history may be absent — most cases arise from environmental Clostridium botulinum spore ingestion.
Bulbar failure (pooled secretions, weak cry, poor feeding) precedes respiratory failure — secure the airway early; do not wait for desaturation.
Human-derived botulism immune globulin (BIG-IV, BabyBIG) is the only specific therapy and should be given as soon as the diagnosis is suspected.
Aminoglycosides (gentamicin, tobramycin, amikacin) and clindamycin are absolutely contraindicated — they potentiate neuromuscular blockade and prolong paralysis.
Succinylcholine can be used safely for RSI in infant botulism; rocuronium provides longer paralysis and controlled conditions.
Do not use edrophonium — it can worsen autonomic instability and is unreliable in infants.
Prolonged mechanical ventilation (often 1–4 weeks), autonomic monitoring, NG feeds, and meticulous pulmonary hygiene are the mainstay of supportive care until synaptic regeneration occurs.
