Descriptive Patterns of Ketamine Administration Among Adult Emergency Department Patients at a Single Academic Center in Saudi Arabia.

Abstract

<b>Background/Objectives</b>: Ketamine use in emergency departments is expanding for the management of agitation, procedural sedation, and rapid sequence intubation. We aim to describe the indications and characteristics of ketamine administration in emergency department patients in Saudi Arabia through retrospective chart review. <b>Methods</b>: This was a single-center, retrospective chart review conducted at an academic medical center. The study population included patients who received intravenous (IV) or intramuscular (IM) ketamine in the emergency department between 1 January 2023, and 31 December 2024. Patients younger than 18 years of age or those who were pregnant were excluded. <b>Results</b>: A total of 192 patients were included. The median ketamine dose was 50 mg (a total range of 20-240 mg). Procedural sedation was the primary indication (79%), followed by pain management (12.5%), rapid sequence intubation (4.7%), and agitation (2.1%). Nearly all patients (99.5%) received ketamine intravenously, and 83.9% received it in conjunction with other medications. For procedural sedation, ketofol was the most common combination therapy, accounting for 83.6% of combination cases. No procedural failures, need for additional sedatives, or redosing within an hour were reported for procedural sedation. For pain management, ketamine was predominantly administered for musculoskeletal pain (50%) and was most often used as monotherapy (58.3%). Notably, no documented adverse effects were observed post ketamine administration across all indications. <b>Conclusions</b>: Among patients who received ketamine in emergency departments in Saudi Arabia, its administration was frequent, particularly for procedural sedation and acute pain management. In this study we found no adverse events or procedural failures were documented. Further research is warranted to validate these findings.
