If you are unable to place an IV catheter during CPCR, how should emergency drugs be administered?

Administering emergency drugs intratracheally is the correct choice for situations where intravenous access is not achievable during cardiopulmonary resuscitation (CPCR). This method allows for rapid absorption of the medications directly into the bloodstream via the lungs, which can be crucial in critical situations where every moment counts.

The intratracheal route is particularly effective for specific drugs, such as epinephrine, atropine, and lidocaine, which can be administered this way if IV access is not possible. This technique also bypasses the need for a functioning circulatory system to achieve drug distribution, providing a critical option to enhance the chances of successful resuscitation.

Other methods like subcutaneous, intraperitoneal, or via a stomach tube are generally not suitable for emergency drug administration in CPCR. Subcutaneous administration is too slow for emergencies, intraperitoneal injections require more time for absorption, and using a stomach tube does not provide reliable delivery of medications to the systemic circulation during a life-threatening situation.
