Bilateral Pneumothoraces in a Tandem Parachuting Passenger Without Traumatic Impact: A Case Report.

In parachuting, orthopedic and head injuries are well-documented risks associated with the parachute deployment and landing phases. Thoracic injuries have only been seen on rare occasion in conjunction with direct impact trauma. In this report, we detail a case of a young, healthy, tandem skydiving passenger who suffered bilateral pneumothoraces with delayed symptom onset, with no identifiable injury during the jump or landing. Exploring the forces of the parachute "opening shock," we suggest a plausible compressive mechanism for this novel presentation, as well as briefly discuss the options for diagnosis and conservative management of pneumothorax in the operational context. While this is an exceedingly rare event, pneumothorax should be considered in patients complaining of thoracic symptoms following a skydive.

Rationale and Implementation of a Novel Special Operations Medical Officer Course.

BACKGROUND: The Air Force Special Warfare Medical Officer Course was created to address the lack of operationally focused, job-specific clinical training for medical officers (MOs). This course addresses the gap in knowledge, skill, and application of operational medicine, as well as the behavioral health, human performance, education, and medical oversight of Operators. METHODS: The course was designed around the senior author's decade of experience piecing together training for his own role as a pararescue flight surgeon and informed by 5 years of flight surgeon courses, lessons learned from case studies of ill-prepared deployed physicians, and input from prehospital medicine subject matter experts. RESULTS: Air Force pararescue and special tactics flight surgeons, physician assistants, and an independent duty medical technician (IDMT) attended. The course consisted of 10 full weekdays of didactics and skills sessions covering theory and application of operational medicine, human performance optimization, behavioral health for Operators, adult education theory, principles of prehospital clinical oversight, and other expeditionary concepts. The course culminated with combat casualty care scenario-based exercises, in which the providers performed operational medicine in full kit with weapons and simulation rounds. DISCUSSION: For many logistical and practical reasons, civilian medical experience, traditional military medical training, existing special operations medical courses, and "merit badge" card classes are not adequate preparation for this specialized role. Focused, job-specific training should be provided to Special Operations Forces Medical Officers (SOFMO) and, ultimately, to any MO deploying in support of medics or combatants. The goal is to maximize the success of military medical operations while reducing the morbidity and mortality of combat and training casualties. CONCLUSION: This operationally focused MO course can serve as a model for the future training of SOFMO and has stimulated discussion for consideration of a joint approach to prehospital medical training.

Major Trauma Outside a Trauma Center: Prehospital, Emergency Department, and Retrieval Considerations.

Care of the critically injured begins well before the patient arrives at a large academic trauma center. It is important to understand the continuum of care from the point of injury in the prehospital environment, through the local hospital and retrieval, until arrival at a trauma center capable of definitive care. This article highlights the important aspects of trauma assessment and management outside of tertiary or quaternary care hospitals. Key elements of each phase of care are reviewed, including management pearls and institutional strategies to facilitate effective and efficient treatment of trauma patients from the point of injury forward.

Time on the scene and interventions are associated with improved survival in pediatric out-of-hospital cardiac arrest.

BACKGROUND: Survival is less than 10% for pediatric patients following out-of-hospital cardiac arrest. It is not known if more time on the scene of the cardiac arrest and advanced life support interventions by emergency services personnel are associated with improved survival. AIM: This study was performed to determine which times on the scene and which prehospital interventions were associated with improved survival. METHODS: We studied patients aged 3 days to 19 years old with out-of-hospital cardiac arrest, using the Resuscitation Outcomes Consortium cardiac arrest database from 11 North American regions, from 2005 to 2012. We evaluated survival to hospital discharge according to on-scene times (<10, 10 to 35 and >35 min). RESULTS: Data were available for 2244 patients (1017 infants, 594 children and 633 adolescents). Infants had the lowest rate of survival (3.7%) compared to children (9.8%) and adolescents (16.3%). Survival improved over the 7 year study period especially among adolescents. Survival was highest in the 10 to 35 min on-scene time group (10.2%) compared to the >35 min. group (6.9%) and the <10 min. group (5.3%, p=0.01). Intravenous or intra-osseous access attempts and fluid administration were associated with improved survival, whereas advanced airway attempts were not associated with survival and resuscitation drugs were associated with worse survival. CONCLUSIONS: In this observational study, a scene time of 10 to 35 min was associated with the highest survival, especially among adolescents. Access for fluid resuscitation was associated with increased survival but advanced airway and resuscitation drugs were not.

Novel use of a hemostatic dressing in the management of a bleeding leech bite: a case report and review of the literature.

Persistent bleeding from leech bites is a common occurrence, although little evidence is available to guide management. Detailed here is the case of a 30-year-old American man who presented with two leech bites after a trek through the jungle in Nepal, one of which continued to briskly ooze blood despite standard wound care. The wound was ultimately treated with QuikClot gauze, which allowed for rapid hemostasis without rebleeding. This case report describes the first use of a hemostatic dressing for this purpose, and reviews what is known about hemostatic agents and about leeches in order to discuss how they make us bleed and what to do when a leech bite occurs.
