Ukraine's health and trauma system has been detrimentally impacted since the Russian Federation invasion in February 2022. The number and extent of injuries experienced in Ukraine because of trench warfare and high-intensity large-scale combat operations has not been seen in recent conflicts. Understanding attitudes and perceptions around the use of devices and products including MOVES (monitor, oxygen concentrator, ventilator, and suction system) and its use in the large-scale combat operation environment can inform lessons learned for improved prehospital care in Ukraine, as well as in other future conflicts. ⋯ MOVES SLC is well regarded by Ukrainian trauma care providers. Training may be necessary to increase the quality of care when utilizing these devices, and vehicle modifications may be necessary for use given some concerns over the equipment falling during transport. There is a need to study how this equipment improves the ability of limited medical personnel to provide prolonged care for a larger number of patients with reduced medical resupply.

Despite the use of body armor, emergency operable pulmonary trauma (EOPT) remains a major cause of battlefield morbidity and mortality. While EOPT during military conflicts has some features that distinguish it from EOPT in civilian settings, the 2 occurrences demonstrate overall parallel findings related to presentation, management, and outcome. The goals of the present study were to provide a descriptive analysis of the nature of EOPT and its management at a level 1 trauma center and to determine the associations between EOPT patient demographics and/or patient management and outcome in order to better understand battlefield EOPT. ⋯ The most common indication for EOPT surgery was uncontrolled hemorrhage. The most frequent operation performed for this EOPT cohort was a laparotomy for diaphragmatic repair. A total of 91.5% of EOPT surgery was performed without OLV, an unexpected finding. When OLV occurred, it was equally likely to involve an SLETT with mainstem bronchus insertion, an SLETT with bronchial blocker, or a double-lumen endotracheal tube. The most common indication for OLV was surgical exposure. More extensive injury (expressed as an injury severity score), preadmission endotracheal intubation, and a shorter time from EOPT to operating room arrival were associated with increased odds ratios for mortality. A better understanding of the nature of EOPT at a civilian level 1 trauma center can serve to identify conditions that are associated with more favorable outcomes for EOPT under battlefield conditions and thereby assist in both management decisions and to help prognosticate and triage severely injured patients in that setting.

To determine the proportion and characteristics of injured rural residents treated at urban trauma centers (TCs), urban non-trauma centers (NTCs), rural TCs, and rural NTCs. ⋯ Rural non-trauma centers provided initial care for more than half of injured rural residents, including 2 in 5 of those with the most severe injuries, and managed more than 3 in 4 definitively. These hospitals may be an under-recognized component of the US trauma system.

Military personnel exposed to blasts receive repeated subconcussive head impacts. Although these events typically do not cause immediate symptoms and do not lead to medical evaluation, the cumulative effects of subconcussive impacts can be significant and can include postconcussive symptoms, changes in brain structure and function, long-term cognitive dysfunction, depression, and chronic traumatic encephalopathy. Retinal measures such as thickness of retinal neural layers, density of retinal microvasculature, and strength of retinal neuronal firing are associated with cognitive function and brain structure and function in healthy populations and in neurodegenerative disease cohorts, and changes over time in retinal indices predict cognitive decline and brain atrophy in longitudinal studies in a range of medical populations. ⋯ Despite this, preclinical and human evidence suggests that they could be among the most effective methods for tracking central nervous system damage in people exposed to repeated blasts. Retinal biomarkers could also contribute to brief test batteries to determine who is most at risk for long-term negative effects of future exposures. In addition, the sensitivity of retinal indices to blast exposure and mild traumatic brain injury suggests that they should be incorporated into research on strategies to minimize or prevent blast-related short- and long-term central nervous system changes in blast-exposed military personnel.

Pneumothorax (PTX) incidence in patients arriving to a trauma center can be as high as 20%. The severity of PTX can range from insignificant to life-threatening. Five percent of combat casualties sustaining thoracic trauma have tension PTX (tPTX) at the time of death. Rapid diagnosis and decompression, traditionally with a needle decompression in the prehospital setting, is essential. However, high iatrogenic injury rates reveal a need for a device with the potential to decrease injury rate without compromising decompression success. The Donaldson Decompression Needle (DDN) is a 10-gauge × 3.25 inch needle with a locking mechanism designed to prevent over-insertion. During insertion, a spring-loaded blunt tip retracts, releasing the lock. After penetration of the parietal pleura, the blunt tip projects forward, which in turn locks the device in place on the chest. The device also contains an integrated 1-way valve (OWV) to prevent causing iatrogenic PTX, if placed into a healthy lung cavity. ⋯ Despite the similar length and gauge of the DDN compared to the standard of care (SOC), the success rate of thoracic decompression was lower for the DDN when compared to the SOC (46% vs. 87%, P = .077) although statistical noninferiority was not established. Additionally, intradevice comparisons indicated decompression with the OWV on significantly prolonged decompression time when compared to when it was removed. It could be appropriate to consider removing the OWV after placement to decrease the decompression time, followed by reattachment for transport. Further research into the ability of the DDN to decrease iatrogenic injury will follow validation of decompression capabilities.
