Deployed Combat Use of Methoxyflurane for Analgesia

Schauer S, Fisher AD, April MD. 24(1). 81 - 84. (Journal Article)

Abstract

Background: The U.S. Military needs fast-acting, non-opioid solutions for battlefield pain. The U.S. Military recently used morphine auto-injectors, which are now unavailable. Off-label ketamine and oral transmucosal fentanyl citrate use introduces challenges and is therefore uncommon among conventional forces. Sublingual suftentanil is the only recent pain medication acquired to fill this gap. Conversely, methoxyflurane delivered by a handheld inhaler is promising, fast-acting, and available to some partner forces. We describe methoxyflurane use reported in the Department of Defense Trauma Registry (DODTR). Methods: We requested all available DODTR encounters from 2007 to 2023 with a documented intervention or assessment within the first 72 hours of care. We analyzed casualties who received methoxyflurane in the prehospital setting using descriptive statistics. Results: There were 22 encounters with documented methoxyflurane administration. The median patient age was 23 (range 21-31) years. All were men. The largest proportion was partner force (50%), followed by U.S. Military (27%). Most (64%) sustained battle injuries. Explosives were the most common mechanism of injury (46%), followed by firearms (23%). The median injury severity score was 5 (range 1-17). The most frequent injuries were serious injuries to the extremities (27%), and 23% of patients (5) received a tourniquet. One-half of the casualties received concomitant pain medications. Only three casualties had multiple pain scores measured, with a median pain score change of -3 on a scale of 10. Conclusion: Methoxyflurane use in deployed combat shows both feasibility and usability for analgesia.

Management of Rib Fractures in the Combat Environment

Abstract

Rib fractures in combat casualties are an under-appreciated injury, and their treatment may become more common as more patients survive because of modern body armor and point-ofinjury care. The combat environment has challenges such as equipment availability and sterility. A simple and thoughtful rib fracture treatment algorithm may be useful to reduce the morbidity and mortality of rib fractures in the combat environment. Intravenous lidocaine infusions for patients with traumatic rib fractures may have important combat applications. We propose an algorithm for the management of combat casualties with traumatic rib fractures.
