Combat casualties in Afghanistan cared for by a single Forward Surgical Team during the initial phases of Operation Enduring Freedom

BACKGROUND: The 274th Forward Surgical Team (FST) was the first FST deployed to Bagram, Afghanistan, to provide surgical care for combat casualties during the initial phases of Operation Enduring Freedom. This is an analysis of the distribution, cause, and severity of wounds for combat casualties and the surgical procedures they required. METHODS: A prospective database was maintained for combat casualties cared for by the 274th FST. The database included demographic data, vital status, mechanism of injury, distribution and severity of wounds, and surgical care provided. RESULTS: The FST cared for 224 combat casualties, including 153 U.S. soldiers, 19 coalition soldiers, 32 Afghan militia forces soldiers, and 20 detainees. Fragments were the most common mechanism of injury (49%), and the extremity was the most common location of injury (58%), whereas gunshot wounds were the most common cause of death (57%). There were few significant head, chest, or abdominal wounds (13%). The FST treated 103 surgical cases (73 with combat wounds), including neurosurgical, thoracic, general, orthopedic, and vascular cases, with a total of 180 procedures. CONCLUSIONS: The distribution, cause, and severity of wounds were similar to those in the Persian Gulf War, despite the obvious differences between these conflicts. The use of modern technologies, such as compact, portable, ultrasound and digital X-ray systems, expanded the capabilities of the FST. Even low-intensity conflicts can produce significant numbers of combat casualties, and the FST must be manned, trained, equipped, and supplied to treat a wide variety of combat wounds.     

Pregnancy during Operation Iraqi Freedom/Operation Enduring Freedom

OBJECTIVE: The purpose of this study was to evaluate pregnancy during war-time deployment. METHODS: A retrospective review of gynecology visits was evaluated at Camp Doha, Kuwait, from August 2003 through April 2004. Of the 1,737 visits, 77 demonstrated a positive pregnancy test. These charts were evaluated for factors that may lead to important information for future deployments. RESULTS: The average age of the female soldier with a positive pregnancy test in theater was 27 +/- 7 years. The primary presenting complaint was amenorrhea. Ninety-two percent had an ultrasound. Fifty-four percent of visits were active duty, followed by Reserve, National Guard, and civilian government employees. Ninety-two percent were administratively redeployed. Seventy-seven percent of the soldiers became pregnant in country. Twenty-three percent arrived in country pregnant. CONCLUSIONS: Given the number of pregnancies before and during deployment, current screening procedures as well as new concepts in prevention need to be addressed.     

Orthopedic injuries during Operation Enduring Freedom

Orthopedic injuries comprise a majority of combat injuries seen in recent U.S. military conflicts. Interventions in the forward deployed area have played an important role in improving mortality rates of soldiers as well as outcome at a medical center level. A retrospective review was conducted on orthopedic injuries from Operation Enduring Freedom evaluated at Walter Reed Army Medical Center (WRAMC). Patients were grouped into one of five injury categories (open fracture, amputation, arterial injuries, neurological injuries, and soft tissue injury) with evacuation time (days from time of injury to arrival at WRAMC) and procedures performed before arrival at WRAMC evaluated. The average evacuation time for all orthopedic casualties was 7.9 days. There was an average of 2.6 procedures performed per patient before arrival at WRAMC. There was no difference in evacuation time among the injury groups. Those with only soft tissue injuries underwent fewer procedures than the other injury groups; however, there was no difference among the injury groups in terms of procedures performed. The number of procedures performed did not affect the evacuation time. Fifty-six percent of casualties required operative intervention after arrival at WRAMC. With the unavoidable evacuation time that all casualties must endure regardless of severity of the injury, early operative intervention in forward deployed medical assets, such as the forward surgical team and combat support hospital, remains a necessity for rehabilitative and reconstructive efforts of the soldiers at the medical center level.     

Operation Enduring Freedom: the 48th Combat Support Hospital in Afghanistan

OBJECTIVE: To examine the experience of the 48th Combat Support Hospital (CSH) while deployed to Afghanistan, with an emphasis on trauma care. MATERIALS AND METHODS: Before redeployment, a retrospective review was performed on the medical records of all patients treated at the 48th CSH from December 6, 2002 through June 7, 2003. RESULTS: During the 6-month period, 10,679 patients were evaluated and/or treated. There were 477 hospital admissions (adults, 387; children, 90; trauma, 204) and 634 operating room procedures. The most common mechanisms of injury were land mines/unexploded ordinance (74 = 36%) and gunshot wounds (41 = 20%). Extremities were the most common site. A total of 358 cases was performed on 168 trauma patients (mean, 2 cases per patient; range, 1-12). There were 63 complications in 40 trauma patients and 11 patients died. CONCLUSIONS: The 48th CSH supported military and humanitarian operations with an ongoing process of re-evaluation, adaptation, and medical education that resulted in low morbidity and mortality rates.     

Operation Iraqi Freedom: surgical experience of the 212th Mobile Army Surgical Hospital

Seven hundred one patients were treated at and 394 were admitted to the 212th Mobile Army Surgical Hospital in Central Iraq during the combat phase of Operation Iraqi Freedom. Ninety of those patients underwent 100 operations, with 187 procedures in 19 days. At the peak of hostilities, 48 patients were admitted, 15 operations were performed, and 56 patients were medically evacuated during different 24-hour periods. Thirty-three patients required the surgical expertise of a general or thoracic surgeon. Although 82% of injuries and 70% of the procedures were orthopedic in nature, orthopedic operating room utilization was only 60% of total operating room time (156 hours). The general and thoracic injuries were labor-intensive, frequently requiring two surgeons. Although orthopedic injury remains the predominant reason for surgical intervention on the battlefield, there remains a need to forward-deploy general and thoracic surgeons, because of the presence and complexity of nonorthopedic trauma.     

Combat casualty care: the Alpha Surgical Company experience during Operation Iraqi Freedom

BACKGROUND: Operation Iraqi Freedom was the first large-scale combat operation involving the U.S. Marine Corps since the Persian Gulf War in 1991. Data from a combat surgical company are presented. METHODS: Records of all U.S. and Iraqi combat casualties admitted to the surgical company were reviewed. RESULTS: Fifty-three (57%) of 93 patients suffered penetrating injuries. Most wounds were produced by high-explosive munitions (mines, hand grenades, and rocket-propelled grenades), and the majority (51%) of wounds were to the extremities. The time to surgical care averaged 4.7 hours (range, 1.5-48 hours), and 98% of the patients seen at our facility survived. CONCLUSIONS: The time from injury to surgical care was considered long by civilian standards; however, this did not appear to affect outcomes substantially. A small percentage (5.2%) of injuries were to the torso. Hypothermia was commonly present. Because of the nature of their wounds, all patients required additional surgery after evacuation to rear area facilities. The outcomes of individual patients are not known, although it is known that only one Marine died after reaching medical care and, to date, no Marines have subsequently died of their wounds.

Utility of ultrasound in the combat theater: experiences of a gynecologist during Operation Iraqi Freedom/Operation Enduring Freedom

OBJECTIVE: The purpose of this study was to evaluate the utility of ultrasound in a combat theater. METHODS: A retrospective review of gynecology visits was evaluated at Camp Doha, Kuwait, from August 2003 through April 2004. Of the 1,737 visits, 237 required pelvic ultrasound. Demographic information, as well as the indications, diagnosis, and disposition of the patients, was compiled. RESULTS: The average age of the patient requiring ultrasound was 28 +/- 8 years. The primary presenting complaint was pelvic pain. Forty percent with pelvic pain had no identifiable cause. The most common final diagnosis was pregnancy. Of the 237 visits, the use of ultrasound resulted in 136 return-to-duty dispositions. Of the 31% who were administratively redeployed, the majority were secondary to pregnancy. CONCLUSION: Gynecologic ultrasound was found to be a very useful tool in the combat theater. Ultrasound resulted in improved diagnostic ability and enhanced reassurance to both provider and patient.     

A review of 41 upper extremity war injuries and the protective gear worn during Operation Enduring Freedom and Operation Iraqi Freedom

Forty-one patients with upper extremity war injuries sustained during combat operations Operation Enduring Freedom and Operation Iraqi Freedom were reviewed to report on protective gear availability and usage at the time of injury. Participants treated at the Madigan Army Medical Center occupational therapy clinic from August 2004 until February 2005 completed a questionnaire regarding injuries sustained during deployment. Overall, 6 injuries were to upper extremity regions that were covered with issued protective gear; 21 injuries were to areas not covered with issued protective gear (i.e., participant was not wearing issued gear), and 22 injuries were to regions that were not covered because no protective gear was issued for that body area. Although this study is limited, future research would provide valuable insights about the efficacy of current body armor and the need for additional or modified gear.     

The most frequently requested precombat refresher training by the Special Forces medics during Operation Enduring Freedom

The tactical environment and the mission given the Special Operations Forces in Afghanistan during the initial phases of Operation Enduring Freedom placed the Special Operations Forces medics (18Ds) in a position of significant medical responsibility. The 18Ds became the primary care providers for the indigenous anti-Taliban fighters as well as U.S. military personnel; the care of the latter was further complicated by long evacuation times. Because of these issues and several events that occurred in the combat zone, the 18Ds requested their supporting forward surgical team (FST) (274th FST) to provide specific refresher training before combat deployment into Afghanistan. The areas of greatest interest and concern were orthopedics, field transfusions, and field-expedient anesthesia. It is hoped that the training prepared and given to the 18Ds by the personnel of the 274th FST and presented in this article not only was useful to them but also will be of benefit to 18Ds who find themselves in similar situations in the future.     

Visceral leishmaniasis in a soldier returning from Operation Enduring Freedom

This report presents a case of visceral leishmaniasis in a soldier returning from Operation Enduring Freedom. During the United States' last major military conflict, Operation Desert Storm, the diagnosis of multiple cases of visceral leishmaniasis led to policy changes, including a temporary ban on troop blood donation. This case demonstrates the applicability of recently developed Leishmania polymerase chain reaction and serological assays when conventional methods of diagnosis, such as tissue microscopy and culture, fail.     

Review of non-battle injuries in Air Force personnel deployed in support of Operation Enduring Freedom and Operation Iraqi Freedom

This study examines non-battle injuries among U.S. Air Force members deployed during Operations Iraqi and Enduring Freedom. A cohort of 275,843 Active Duty, Guard, and Reserve members were identified for the period September 11, 2001 through October 31, 2006. Data on injuries were obtained from electronic medical records and deployment time was obtained from manpower records. Poisson regression was used to estimate adjusted incidence rate ratios (IRRs). The most common non-battle injuries were sprains and strains (53%) followed by open wounds (27%). Guard and Reserve members tended to have a lower rate of orthopedic non-battle injuries than Active Duty members in crude analyses and after adjustment for age, previous deployment, sex, race/ethnicity, and occupation (IRR = 0.95; 95% CI = 0.89-1.02 and IRR = 0.85; 95% CI = 0.77-0.93). Results from this study are intended to facilitate further research of potential differences between Air Force components to reduce non-battle injuries in a deployed environment.     

Dental emergency rates at an expeditionary medical support facility supporting Operation Enduring Freedom

The purpose of this study was to report the dental emergency rate and the distribution of cause of dental emergencies at an Expeditionary Medical Support +25 medical facility during a 6-month deployment in support of Operation Enduring Freedom. A retrospective cohort analysis of 1,972 soldiers stationed at Seeb Air Base, Sultanate of Oman, was accomplished from a phased deployment from March to September 2002. Procedures were divided into 11 categories: endodontic, extraction of teeth other than third molars, extraction of third molar teeth, restoration of teeth (caries), restoration of broken teeth (not caries), orthodontic bracket/wire problem, sensitive teeth, temperomandibular pain, periodontal, oral pathology, and prosthodontic. One hundred thirty-five dental emergency visits were recorded, corresponding to a rate of 137 dental emergencies per 1,000 soldiers per year. Most of the emergencies (34.8%) were due to caries. Pain from third molars was the second most common reason for visiting the dental clinic (19.3%).     

Effects of transcendental meditation in veterans of Operation Enduring Freedom and Operation Iraqi Freedom with posttraumatic stress disorder: a pilot study

We conducted an uncontrolled pilot study to determine whether transcendental meditation (TM) might be helpful in treating veterans from Operation Enduring Freedom or Operation Iraqi Freedom with combat-related posttraumatic stress disorder (PTSD). Five veterans were trained in the technique and followed for 12 weeks. All subjects improved on the primary outcome measure, the Clinician Administered PTSD Scale (mean change score, 31.4; p = 0.02; df = 4). Significant improvements were also observed for 3 secondary outcome measures: Clinician's Global Inventory-Severity (mean change score, 1.60; p < 0.04; df = 4), Quality of Life Enjoyment and Satisfaction Questionnaire (mean change score, -13.00; p < 0.01; df = 4), and the PTSD Checklist-Military Version (mean change score, 24.00; p < 0.02; df = 4). TM may have helped to alleviate symptoms of PTSD and improve quality of life in this small group of veterans. Larger, placebo-controlled studies should be undertaken to further determine the efficacy of TM in this population.     

Operation Enduring Freedom: trends in combat casualty care by forward surgical teams deployed to Afghanistan

This study examined the clinical experience of a U.S. Army Forward Surgical Team (FST) deployed to Afghanistan in 2005 and compared the findings with those of 3 previously deployed FSTs. Medical records of all patients evaluated by the FST were abstracted for analysis. Demographically, the cohort (n = 614) was predominantly male (94%), with a median age of 24, and distributed according to the following: disease (8.6%), nonbattle injury (42%), and battle injury (49%). Combat casualties were mostly Afghan National Army or Police (56%) and U.S. military (21%). Predominant wounding instruments were small arms (34%), improvised explosive devices (33%), and rocket-propelled grenades (15%). Anatomical sites of battle injury were extremities (38%), external soft tissue (35%), and head/neck/torso (28%). Operative procedures for combat injury (n = 227) were primarily orthopedic (45%) or thoracic/abdominal (36%). Combat casualty statistics provide insight to trauma epidemiology, patterns, and trends vital for surgical management. Workload statistics guides the structuring, training, and employment of FSTs.     

Drowning deaths of U.S. Service personnel associated with motor vehicle accidents occurring in Operation Iraqi Freedom and Operation Enduring Freedom, 2003-2005

OBJECTIVE: We examined common factors in vehicular drowning deaths that might lead to changes in equipment or training. METHODS: Drowning deaths among service members deployed to Operations Iraqi Freedom or Enduring Freedom, 2003 to 2005, were ascertained using the Armed Forces Medical Examiner Tracking System database. Cases were linked to Army and Navy safety and investigative files. RESULTS: Fifty-two cases of vehicular drowning deaths were identified. These occurred mostly at night, were almost always the result of a rollover, and were most frequently associated with a high-mobility medium-weight vehicle. Seat belts were rarely worn, but the majority of injuries should not have been severe enough to affect egress from the vehicle. These drowning deaths seldom occurred while engaged with the enemy and were rarely associated with bad road conditions or bad weather. CONCLUSIONS: Effective preventive strategies might focus on training and equipment to reduce rollover events and on the expeditious extrication of victims.
