Abstract
Objective: To present the main complications of the drugs used during a CPA and how to conduct assistance from this use. Bibliographic review: Cardiorespiratory Arrest (PCR) is one of the greatest challenges for the team of health professionals in the hospital environment. Several procedures are performed with the aim of maintaining the patient's cardiorespiratory functions. Among these important procedures, medication administration is being performed, which contributes to the restoration of the patient's vital functions. Thus, it is important that the pharmacological properties of these drugs are marked in order to understand the expected effects and the iatrogenies or complications arising from this use. The drugs found to be useful during a PCR were adrenaline, vasopressin, amiodarone, lidocaine and magnesium sulfate. All of these substances have their own characteristics regarding their use and the possibility of causing adverse effects, such as peripheral nervous system and cardiovascular problems. Within it, the procedures and care that should be taken with the patient in PCR were highlighted. Final Considerations: The nursing team needs to be attentive to the knowledge of these complications, as well as their identification so that it can further improve the care of patients with this condition so challenging that it is a CRP.
