Operation Enduring Freedom (OEF) and Operation Iraqi Freedom (OIF) have resulted in a growing number of seriously injured soldiers who are evacuated to the United States for comprehensive medical care. Trauma-related pain is an almost universal problem among these war-injured soldiers, and several military and Department of Veterans Affairs initiatives have been implemented to enhance pain care across the continuum of medical services. This article describes several innovative approaches for improving the pain care provided to OEF and OIF military personnel during acute stabilization, transport, medical-surgical treatment, and rehabilitation and presents summary data characterizing the soldiers, pain management services provided, and associated outcomes. We also identify some of the pain assessment, classification, and treatment challenges emerging from work with this population and provide recommendations for future research and practice priorities.

Pain and combat injuries in soldiers returning from Operations Enduring Freedom and Iraqi Freedom: implications for research and practice.

Background After the invasion of Iraq in April 2003, coalition forces have remained in the country in a bid to maintain stability and support the local security forces. The improvised explosive device (IED) has been widely used by the insurgents and is the leading cause of death and injury among Coalition troops in the region. Method From January 2006, data were prospectively collected on 100 consecutive casualties who were either injured or killed in hostile action. Mechanism of injury, new Injury Severity Score (NISS), The International Classification of Disease-9th edition diagnosis, anatomic pattern of wounding, and operative management were recorded in a trauma registry. The weapon incident reports were analyzed to ascertain the type of IED employed. Results Of the 100 casualties injured in hostile action, 53 casualties were injured by IEDs in 23 incidents (mean 2.3 casualties per incident). Twenty-one of 23 (91.3%) of the IEDs employed were explosive formed projectile (EFP) type. Twelve casualties (22.6%) were either killed or died of wounds. Median NISS score of survivors was 3 (range, 1-50). All fatalities sustained unsurvivable injuries with a NISS score of 75. Primary blast injuries were seen in only 2 (3.8%) and thermal injuries in 8 casualties (15.1%). Twenty (48.7%) of survivors underwent surgery by British surgeons in the field hospital. At 18 months follow, all but one of the United Kingdom Service personnel had returned to military employment. Conclusions The injury profile seen with EFP-IEDs does not follow the traditional pattern of injuries seen with conventional high explosives. Primary blast injuries were uncommon despite all casualties being in close proximity to the explosion. When the EFP-IED is detonated, the EFP produced results in catastrophic injuries to casualties caught in its path, but causes relatively minor injuries to personnel sited adjacent to its trajectory. Improvements in vehicle protection may prevent the EFP from entering the passenger compartments and thereby reduce fatalities.

Injuries from roadside improvised explosive devices.

The improvised explosive device (IED), in all its forms, has become the most significant threat to troops operating in Afghanistan and Iraq. These devices range from rudimentary home made explosives to sophisticated weapon systems containing high-grade explosives. Within this broad definition they may be classified as roadside explosives and blast mines, explosive formed pojectile (EFP) devices and suicide bombings. Each of these groups causeinjury through a number of different mechanisms and can result in vastly different injury profiles. The "Global War on Terror" has meant that incidents which were previously exclusively seen in conflict areas, can occur anywhere, and clinicians who are involved in emergency trauma care may be required to manage casualties from similar terrorist attacks. An understanding of the types of devices and their pathophysiological effects is necessary to allow proper planning of mass casualty events and to allow appropriate management of the complex poly-trauma casualties they invariably cause. The aim of this review article is to firstly describe the physics and injury profile from these different devices and secondly to present the current clinical evidence that underpins their medical management.

Improvised explosive devices: pathophysiology, injury profiles and current medical management.

Soldiers with a traumatic brain injury (TBI) present with an array of neuropsychiatric symptoms that can be grouped into nosological clusters: (1) cognitive dysfunctions: difficulties in memory, attention, language, visuospatial cognition, sensory-motor integration, affect recognition, and/or executive function typically associated with neocortical damage; (2) neurobehavioral disorders: mood, affect, anxiety, posttraumatic stress, and psychosis, as well as agitation, sleep problems, and libido loss, that may have been caused by damage to the cortex, limbic system, and/or brain stem monoaminergic projection systems; (3) somatosensory disruptions: impaired smell, vision, hearing, equilibrium, taste, and somatosensory perception frequently caused by trauma to the sensory organs or their projections through the brain stem to central processing systems; (4) somatic symptoms: headache and chronic pain; and (5) substance dependence. TBI-related cognitive impairment is common in veterans who have served in recent conflicts in the Middle East and is often related to blasts from improvised explosive devices. Although neurobehavioral disorders such as depression and posttraumatic stress disorder commonly occur after combat, the presentation of such disorders in those with head injury may pass undetected with use of current diagnostic criteria and neuropsychological instruments. With a multidimensional approach (such as the biopsychosocial model) applied to each symptom cluster, psychological, occupational, and social dysfunction can be delineated and managed.

Neuropsychiatric diagnosis and management of chronic sequelae of war-related mild to moderate traumatic brain injury.

Summary Background Following the invasion of Iraq in April 2003, British and coalition forces have been conducting counter-insurgency operations in the country. As this conflict has evolved from asymmetric warfare, the mechanism and spectrum of injury sustained through hostile action (HA) was investigated. Method Data was collected on all casualties of HA who presented to the British Military Field Hospital Shaibah (BMFHS) between January and October 2006. The mechanism of injury, anatomical distribution, ICD-9 diagnosis and initial discharge information was recorded for each patient in a trauma database. Results There were 104 HA casualties during the study period. 18 were killed in action (KIA, 21%). Of the remaining 86 surviving casualties, a further three died of their wounds (DOW, 3.5%). The mean number of diagnoses per survivor was 2.70, and the mean number of anatomical regions injured was 2.38. Wounds to the extremities accounted for 67.8% of all injuries, a percentage consistent with battlefield injuries sustained since World War II. Open wounds and fractures were the most common diagnosis (73.8%) amongst survivors of HA. Improvised explosive devices (IEDs) accounted for the most common cause of injury amongst casualties (54%). Conclusions Injuries in conflict produce a pattern of injury that is not seen in routine UK surgical practice. In an era of increasing surgical sub-specialisation, the deployed surgeon needs to acquire and maintain a wide range of skills from a variety of surgical specialties. IEDs have become the modus operandi for terrorists. In the current global security situation, these tactics can be equally employed against civilian targets. Therefore, knowledge and training in the management of these injuries is relevant to both military and civilian surgeons.

A review of casualties during the Iraqi insurgency 2006–A British field hospital experience

Background:

War wounds produce a significant burden on medical facilities in wartime. Workload from the recent conflict was documented in order to guide future medical needs.



Methods:

All data on war injuries were collected prospectively. This information was supplemented with a review of all patients admitted during the study period.



Results:

During the first 2 weeks of the conflict, the sole British field hospital in the region received 482 casualties. One hundred and four were battle injuries of which nine were burns. Seventy-nine casualties had their initial surgery performed by British military surgeons and form the study group. Twenty-nine casualties (37 per cent) sustained gunshot wounds, 49 (62 per cent) suffered wounds from fragmentation weapons and one casualty detonated an antipersonnel mine. These 79 patients had a total of 123 wounds that were scored prospectively using the Red Cross Wound Classification. Twenty-seven (34 per cent) of the wounded were non-combatants; eight of these were children. Four patients (5 per cent) died.



Conclusion:

War is changing; modern conflicts appear likely to be fought in urban or remote environments, producing different wounding patterns and placing non-combatants in the line of fire. Military medical skills training and available resources must reflect these fundamental changes in preparation for future conflicts. Copyright © 2005 British Journal of Surgery Society Ltd.
