It is recommended to consider prophylaxis
administration of sodium citrate to reduce the risk of pulmonary aspiration at time of
induction of anesthesia. Evaluate serum electrolytes and arterial blood gases, if
recurrent vomiting evident. A complete medical history and physical examination must be
obtained to rule out the presence of reactive airways disease as a result of chronic
aspiration. A chest x-ray and pulmonary function tests are indicated (when applicable).
