Emergency Department Care
Antitoxin should be administered as soon as the clinical diagnosis is established, as laboratory confirmation requires days. The early administration of antitoxin will not reverse the course of the intoxication but will prevent further progression of paralysis. This is the best method to prevent diaphragmatic involvement and the need for mechanical ventilation. Antitoxin can only bind neurotoxin free in the blood. Once in the neuron, it cannot be bound.
Monitor asymptomatic individuals who have eaten food suspected of being contaminated for the appearance of neurologic signs and symptoms.
Enemas and cathartics or whole-bowel irrigation may be used (if no ileus is present) to purge the gut of toxin. If ingestion occurred within the past few hours, emetics or gastric lavage may aid in the removal of toxin.
In infant botulism, most cases progress to complete respiratory failure. Intubation is required for a median of 16-23 days. Tracheostomy usually is not required.
Wound botulism requires thorough debridement of the wound site, even if it appears to be healing well. Follow this by injection of 3% hydrogen peroxide to produce aerobic conditions. Hydrogen peroxide itself is not innocuous to tissues, and some have advocated using hyperbaric oxygen therapy if available.
Antitoxin may be injected directly into the wound site.
Urinary retention may require use of a catheter.
In adults, botulism results in pulmonary complications in 81% of patients, with ventilatory failure in one third.
Monitor spirometry, pulse oximetry, and arterial blood gas measurements, with particular attention placed on serial measurements of maximal static inspiratory pressure and respiratory vital capacity to help in predicting respiratory failure.
Strongly consider intubation and mechanical ventilation when vital capacity is less than 30% of predicted (or < 12 mL/kg), particularly when absolute or relative hypercarbia and rapidly progressive paralysis with hypoxemia are evident.
See the list below:
Medical care providers who suspect botulism in a patient should immediately call their state health department's emergency 24-hour telephone number. The state health department will contact the CDC to report suspected botulism cases, arrange for a clinical consultation by telephone and, if indicated, request release of botulinum antitoxin. State health departments should call the CDC 24-hour telephone number at 770-488-7100. The call will be taken by the CDC Emergency Operations Center, which will page the Foodborne and Diarrheal Diseases Branch medical officer on call.
