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 assess system-wide implementation of specific therapies focused on perfusion during cardiopulmonary resuscitation (CPR) and cerebral recovery after Return of Spontaneous Circulation (ROSC). ⋯ Specific therapies within a system of care (mCPR, HTH), developed to enhance circulation during CPR and cerebral recovery after ROSC, significantly improved survival by 74% with favorable neurologic function following OHCA.

Prehospital care providers are in a unique position to provide initial unadulterated information about the scene where a child is abusively injured or neglected. However, they receive minimal training with respect to detection of Child Abuse and Neglect (CAN) and make few reports of suspected CAN to child protective services. ⋯ Prehospital care providers have a unique vantage point in detecting CAN, but limited resources and knowledge related to this topic. Focused education on recognition of signs of physical abuse; increased training on scene safety; real-time decision support; and increased follow-up related to cases of CAN may improve their detection of CAN.

To characterize the continuity and duration of sleep, and to measure nocturnal cardiac autonomic balance via heart rate variability (HRV) in a group of emergency medical technicians (EMTs) on and off duty. ⋯ EMTs who worked 24-hour shifts had shorter, more fragmented sleep associated with greater cumulative exposure to increased sympathetic and decreased parasympathetic activity as measured via sleep HRV. These changes in cardiac autonomic tone constitute one plausible pathway through which sleep deprivation may increase risk for cardiovascular disease.

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.
