# Use of Analgesics and Sedatives in Nontraumatic Patients after Sudden Cardiac Arrest during the Peri-Resuscitation Period in the Emergency Department

## TL;DR

This study examines how often analgesics and sedatives are used in nontraumatic cardiac arrest patients during resuscitation in emergency departments.

## Contribution

The study provides insights into current practices of analgesia and sedation use in post-cardiac arrest care.

## Key findings

- Chest wall injuries were found in 31% of patients via X-ray and 69% via CT scans.
- 78% of patients received sedatives or analgesics, with midazolam being the most common drug used.

## Abstract

Background: While cardiopulmonary resuscitation (CPR) may be life-saving for patients in cardiac arrest, it simultaneously puts them at risk for skeletal and soft tissue injuries. The prevalence of cardiovascular and thoracic wall injuries related to CPR varies significantly in the literature, from 21% to more than 78%. After restoration of circulation, ischemia–reperfusion brain injury ensues. Sedation is one of the interventions that can reduce its effects on brain cells. The purpose of this study was to analyse the use of analgesics and sedatives in nontraumatic patients after sudden cardiac arrest in the peri-resuscitation period in the emergency department. Methods: This was a retrospective cohort study. An analysis was performed on the electronic health records of 131 patients who underwent CPR, with ages ranging from 24 to 96 years. The study protocol was in accordance with the Declaration of Helsinki. Results: Chest wall injuries were assessed based on the results of X-ray imaging (n = 39; 31%) and computed tomography (n = 87; 69%). Of the 126 cases, 17.5% had rib fractures and 6.3% had rib and sternal fractures. Almost 78% of the patients (n = 102) received sedatives and/or analgesics during the peri-resuscitation period. Monotherapy was used in 85 cases. Among these drugs the most frequently mentioned were midazolam (45.2%), fentanyl (26.8%), and propofol (20.8%). Conclusions: As only two-thirds of the patients received sedation and half received analgesics, there is still room for a broader incorporation of analgesia and sedation into peri-resuscitation care protocols.
