inhalational induction
Method of anesthesia induction using inhaled anesthetic agents, preferred in pediatric patients to avoid the distress of intravenous cannulation.
Full Definition
Inhalational induction is a technique for initiating general anesthesia using volatile anesthetic agents delivered via face mask, rather than intravenous medications. This method is particularly favored in pediatric anesthesia because it avoids the psychological trauma and physical discomfort of needle insertion in awake children. Sevoflurane is the most commonly used agent due to its pleasant odor, rapid onset, and minimal airway irritation. The technique involves gradually increasing the concentration of anesthetic while maintaining spontaneous ventilation until the child loses consciousness and reflexes are obtunded.
Usage
Usage note: Use 'inhalational' rather than 'inhalation' as the adjective form in medical contexts.
