Which drug is NOT administered endotracheally during resuscitation?

The choice of magnesium sulfate as the drug not administered endotracheally during resuscitation stems from the practicality and effectiveness of the route of administration. During cardiac arrest or severe respiratory distress, medications that can be given in this manner must be rapidly effective and safe for the airway.

Drugs like naloxone, lidocaine, and amiodarone have been used in emergency situations and can have a significant impact on recovery when administered via the endotracheal route. Naloxone is used to reverse opioid overdoses; lidocaine can stabilize arrhythmias; and amiodarone is crucial in managing life-threatening cardiac dysrhythmias.

Magnesium sulfate is primarily indicated for specific conditions like torsades de pointes or for the management of severe asthma exacerbations but is less effective when delivered endotracheally. This method can lead to variable absorption and might not be as effective as intravenous administration, especially in critical scenarios where timely action is needed. Therefore, magnesium sulfate is typically given intravenously, ensuring better control over dosage and efficacy during resuscitation efforts.
