Inspiration through -7cm H2O resistance results in an increase in venous blood flow back to the heart and a subsequent increase in cardiac output and blood pressure in hypotensive animals and patients. Breathing through the impedance threshold device with 7cm H2O resistance (ITD-7) also reduces intracranial pressure with each inspiration, thereby providing greater blood flow to the brain. A new device called an ITD-7 was developed to exploit these physiological mechanisms to buy time in hypotensive War Fighters when other therapies are not readily available. Animal and clinical data with the ITD-7 demonstrate the potential value and limitations of this new non-invasive approach to enhancing circulation.

The current war has, like past conflicts, presented the medical community with opportunities to innovate novel approaches to old problems. Although trauma anesthesia is provided adequately in the majority of cases, a standardized approach for treating these complex and critically ill patients is lacking. ⋯ The algorithm is designed as a standardized protocol in an effort to simplify the approach to these complex patients who often present in a dynamic environment. A list of required equipment is included to serve as a guide for preparation prior to employment of the algorithm.

Retrobulbar hemorrhage is an uncommon, but potentially devastating complication associated with facial trauma. It can rapidly fill the orbit and cause an "orbital compartment syndrome" that subsequently cuts off perfusion to vital ocular structures, leading to permanent visual loss. Treatment must be initiated within a limited time in order to prevent these effects; however, specialty consultation is not always available in remote field environments. This article addresses the mechanism, diagnosis, and treatment ofretrobulbar hemorrhage via lateral canthotomy and cantholysis, and recommends that 18D medical sergeants be properly trained to evaluate and perform this sight-saving procedure in emergent settings where upper echelons of care are not immediately available.

Current operational theaters have developed to where medical evacuation and surgical assets are accessible in times comparable to the United States. While this has been an essential tool in achieving the best survivability on a battlefield in our history, the by-product of this experience is a recognized shortcoming in current protocols and capabilities of Special Forces medics for prolonged care. The purpose of this article is to provide a theory of care, identify training and support requirements, and to capitalize on current successful resuscitation theories in developing a more efficient and realistic capability under the worst conditions.

Traumatic brain injury (TBI) is an assault to the brain that disrupts neurological activity. Known as the signature wound of combat during Operations Iraqi Freedom (OIF) and Enduing Freedom (OEF), it has become one of the most common injuries to American Soldiers. While affected Soldiers may remain stable after the primary injury, progressing secondary mechanisms can produce neurological degeneration. ⋯ While previous hypothermic devices were unable to cool rapidly, new technology allows achievement of the goal temperature within 20 minutes. Implementation of such new treatment may show an improvement in neurological outcomes for patients when treatment target temperature is reached within a four-hour window. We recommend that the use of hypothermic medicine should be re-evaluated for its indication in TBI due to the capabilities of a new extremely rapid cooling device.
