Evaluation of High Altitude Interstitial Pulmonary Edema in Healthy Participants Using Rapid 4-View Lung Ultrasound Protocol During Staged Ascent to Everest Base Camp.

Introduction: Prior research identified possible interstitial pulmonary fluid, concerning for early high altitude pulmonary edema (HAPE), in a large percentage of trekkers above 3000 m using a comprehensive 28-view pulmonary ultrasound protocol. These trekkers had no clinical symptoms of HAPE despite these ultrasound findings. The more common 4-view lung ultrasound protocol (LUP) is accurate in rapidly detecting interstitial edema during resource-rich care.

Impact of a Half Dome Cable Permitting Process on Search and Rescue Activity, Hiker Mortality Rates, and Operational Costs Above Little Yosemite Valley.

Introduction: The summit of Yosemite's Half Dome is reached using cable handrails for the final 146 m (480 ft). Access to these cables was restricted to users with permits in 2010. The authors aim to describe the impact of permitting on search and rescue (SAR) in the region of the park most affected by permitting.

Needle Thoracostomy in the Prehospital Setting: A Retrospective Observational Study.

Background: The use of needle thoracostomy (NT) is a common prehospital intervention for patients in extremis or cardiac arrest due to trauma; however, controversy surrounds its use. The purpose of this study is to compare outcomes, effectiveness, and complications of NT in an Emergency Medical Services (EMS) system that includes urban, rural, and wilderness environments.

Methods: This is a retrospective observational study of all patients who had NT performed in a four county EMS system with a catchment area of greater than 1.

Needle Thoracostomy for Patients with Prolonged Transport Times: A Case-control Study.

Unlabelled: Introduction The use of prehospital needle thoracostomy (NT) is controversial. Some studies support its use; however, concerns exist regarding misplacement, inappropriate patient selection, and iatrogenic injury. Even less is known about its efficacy in situations where there is a delay to definitive care.
