In a study with 76 anesthesia providers on a mixed reality simulator, central venous access via the supraclavicular approach to the subclavian vein, without ultrasonography required less attempts compared to the infraclavicular approach. Participants had shorter times to venous access and larger improvements in confidence. ⋯ The use of ultrasonography during the supraclavicular approach to the subclavian vein is also described which may improve its safety profile. This technique could be more appropriate in scenarios when central venous access is preferred over intraosseous access for patients being transported to another location for further care.

Traumatic peripheral nerve injury (TPI) is a major medical problem without effective treatment options. There is no way to diagnose or treat an incomplete injury and delays contribute to morbidity. We examined 4-aminopyridine (4-AP), a potassium-channel blocker as a possible treatment for TPI. ⋯ 4-AP singularly provides both a new potential therapy to promote durable recovery and remyelination in acute peripheral nerve injury and a means of identifying lesions in which this therapy would be most likely to be of value. The ability to distinguish injuries that may respond to extended therapy without intervention can offer benefit to wounded soldiers.

Current military recommendations include the use of tourniquets (TQ) in appropriate pediatric trauma patients. Although the utility of TQs has been well documented in adult patients, the efficacy of TQ application in pediatric patients is less clear. The current study attempted to identify physical constraints for TQ use in two simulated pediatric limb models. ⋯ The current study suggests that commercial windlass TQs can be applied to upper and lower extremities of children aged 5 years and older at the 50%th percentile for limb circumference. In younger children, windlass TQ efficacy is variable. Further study is required to better understand the limitations of TQs in the youngest children, and to determine actual hemorrhage control efficacy.

Randomized Controlled Trial Multicenter Study
Restrictive Transfusion Strategy Is More Effective in Massive Burns: Results of the TRIBE Multicenter Prospective Randomized Trial.
Studies suggest that a restrictive transfusion strategy is safe in burns, yet the efficacy of a restrictive transfusion policy in massive burn injury is uncertain. Our objective: compare outcomes between massive burn (≥60% total body surface area (TBSA) burn) and major (20-59% TBSA) burn using a restrictive or a liberal blood transfusion strategy. ⋯ A restrictive transfusion strategy may be beneficial in massive burns in reducing ventilator days, ICU days and blood utilization, but does not decrease infection, mortality, hospital LOS or wound healing.

Randomized Controlled Trial Multicenter Study
Modified Battlefield Acupuncture Does Not Reduce Pain or Improve Quality of Life in Patients with Lower Extremity Surgery.
This study seeks to determine if modified Battlefield Acupuncture is more effective at relieving acute extremity pain, reducing medication use, and improving quality of life than placebo acupuncture or standard care after lower extremity surgery. ⋯ The use of modified battlefield acupuncture protocol does not change pain opioid use or quality of life in those with lower extremity surgery.
