Medical Care
- Supportive care for the duration of the paralytic illness, with extensive nursing support, is the mainstay of treatment.
- Ventilatory support: In adults, ventilatory support will be needed in as many as one third of cases. Pulse oximetry, arterial blood gas analysis, and spirometry should be monitored. Mechanical ventilation is considered when vital capacity is less than 30% of predicted.
- Parenteral nutrition may be required in view of gastrointestinal disturbance.
- Urinary catheterization may be required for urinary retention.
- Antitoxin: In food-borne illness, trivalent (types A, B, and E) equine antitoxin should be administered, with antitoxin neutralizing botulinum toxin not yet bound to nerve terminals. Therefore, the antitoxin should be given as soon as possible, prior to receiving laboratory confirmation of diagnosis. Antitoxin has not been shown to be beneficial in infant botulism. Human botulism immune globulin is being evaluated for infant botulism.
- Antibiotics may be helpful in the eradication of C botulinum in wound botulism, but they appear to have no role in infant botulism or in botulism of food poisoning. Remember that aminoglycoside antibiotics and tetracyclines may increase neuromuscular blockade by impairment of neuronal calcium entry.
Surgical Care
- In wound botulism, exploration and extensive surgical debridement of infected wounds is required.
