Case Reports
Prehospital Dextrose Extravasation Causing Forearm Compartment Syndrome: A Case Report.
A 57-year-old woman was found at home by paramedics to be hypoglycemic with altered mental status. She had multiple attempts at IV access and eventually a 22G IV was established and D50 was infused into her right forearm. Extravasation of the dextrose was noted after approximately 12 g of the medication was infused. She was given a dose of glucagon intramuscularly and her mental status improved. Shortly after her arrival to the emergency department, she was noted to have findings of compartment syndrome of her forearm at the site of the dextrose extravasation. She was evaluated by plastic surgery and taken to the operating room for emergent fasciotomy. She recovered well from the operation. ⋯ D50 is well known to cause phlebitis and local skin necrosis as a complication. This case illustrates the danger of compartment syndrome after D50 extravasation. It is the first documented case of prehospital dextrose extravasation leading to compartment syndrome. There may be safer alternatives to D50 administration and providers must be acutely aware to monitor for D50 infusion complications.

Observational Study
D10 in the Treatment of Prehospital Hypoglycemia: A 24 Month Observational Cohort Study.
Prehospital first responders historically have used an IV bolus of 50 mL of 50% dextrose solution (D50) for the treatment of hypoglycemia in the field. A local Emergency Medical Services (EMS) system recently approved a hypoglycemia treatment protocol of IV 10% dextrose solution (D10) due to occasional shortages and higher cost of D50. We use the experience of this EMS system to report the feasibility, safety, and efficacy of this approach. ⋯ The results of one local EMS system over a 104-week period demonstrate the feasibility, safety, and efficacy of using 100 mL of D10 as an alternative to D50. D50 may also have theoretical risks including extravasation injury, direct toxic effects of hypertonic dextrose, and potential neurotoxic effects of hyperglycemia. Additionally, our data suggest that there may be little or no short-term decrease in blood glucose results after D10 administration.

To describe the use of prehospital ultrasonography (PHUS) to support interventions, when used by physician and non-physician air medical crew (AMC), in a Canadian helicopter emergency medical service (HEMS). ⋯ The use of PHUS by both physicians and non-physicians was found to support interventions in select trauma and medical patients. Key words: emergency medical services; aircraft; helicopter; air ambulance; ultrasonography; emergency care, prehospital; prehospital emergency care.

Tourniquet use by Emergency Medical Services (EMS) can be life saving for severely injured patients. The adoption of this intervention is not well described in civilian settings. This study describes patterns and trends of tourniquet use by civilian EMS and identifies predictors of such use. ⋯ Reported tourniquet use by EMS for injured patients in the U.S. is low. Increasing adoption mainly by urban services was noted. Predictors for tourniquet use in civilian trauma were identified. Establishing the effectiveness of this intervention by comparing patient outcomes is needed. Key words: emergency medical services; prehospital; tourniquet; injury; NEMSIS; hemorrhage.
