Study Notes
Local Anesthesia Methods for Tracheal Intubation
- Topical anesthesia can be applied to the upper airway using local anesthetic sprays or gels.
- Translaryngeal injection of local anesthetics can provide direct anesthesia to the vocal cords and surrounding tissues.
- Lidocaine can be administered via nebulization for a non-invasive approach to anesthetize the airway.
Approaches to Tracheal Intubation under General Anesthesia
- Two main approaches include the conventional endotracheal intubation through the mouth and the use of a laryngeal mask airway (LMA) followed by intubation.
- Alternatively, video-assisted techniques provide visualization to facilitate accurate placement of the endotracheal tube.
Usual Approach for Tracheal Intubation under General Anesthesia
- The most common method is orotracheal intubation, wherein the endotracheal tube is inserted through the oral cavity past the vocal cords into the trachea.
- This procedure typically requires the use of muscle relaxants to minimize airway reflexes and paralysis of pharyngeal muscles.
Purpose of Pre-Oxygenation in Relaxant Anesthesia
- Pre-oxygenation increases the patient's oxygen reserves prior to intubation, which is crucial in case of hypoventilation or difficulty during the procedure.
- It aims to delay the onset of hypoxia during the period between the administration of muscle relaxants and successful intubation.
Recommended Dose of Succinylcholine for Intubation
- The standard dosing for Succinylcholine in relaxed anesthesia technique is 1 to 1.5 mg/kg administered intravenously.
- This medication induces rapid muscle relaxation, facilitating intubation within 30 to 60 seconds of administration.
