Prehospital Hypertonic Saline Administration After Severe Traumatic Brain Injury.

A 25-year old male paient was critically injuried in a high speed motor vehicle collision over an hour from the nearest trauma center. Paramedics diagnosed the patient with a traumatic brain injury and increasing intracranial pressure and transported the patient to a predesignated landing zone for helicopter intercept. During transport paramedics initiated a severe traumatic brain injury protocol which included the adminisration of 3% hypertonic saline. The flight crew continued 3% hypertonic saline managment which was later transferred to the receiving trauma team. Upon trauma center arrival the patient was diagnosed with a skull fracture and subdural hematoma. The patient was transitioned to a 3% hypertonic saline infusion for the next 24 h. The need for integrating systems of care is particularly important when managing patients with severe traumatic brain injury. This case report describes a patient with a severe TBI who received prehospital 3% hypertonic saline based on an integrated protocol developed between multiple prehosptial systems and a tertiary care trauma center. Severe traumatic brain injuries (TBIs) are a potentially catastrophic event, and morbidity can rise precipitously without early interventions to prevent hypoxia and hypotension and control for rising intracranial pressure. In recent years, hypertonic saline (HTS) has shown efficacy in lowering intracranial pressures for patients experiencing TBIs, the leading cause of death and disability among children and young adults in the United States.1 Integrating care between health care providers across the acute care continuum, from prehospital systems to discharge, is paramount in providing the best patient outcomes possible, especially in health care system expansions such as air medical transport. The need for integrating systems of care is particularly important when managing patients with severe TBI. Statewide prehospital care protocols vary greatly; 78% provide ventilation guidance, 77.3% have targeted end-tidal carbon dioxide levels below < 35 mm Hg, and only 1 (of 38 reviewed) includes HTS (3%).2 One barrier to consistency in protocol development is the available literature. One trial demonstrated that a prehospital bolus of 7.5% HTS in severe TBI did not improve mortality.3 However, the Brain Foundation guidelines continue to recommend the prehospital use of hyperosmolar therapy for patients with severe TBI and evidence of impending herniation.4 Hyperosmolar therapy is also recommended as an inpatient strategy for lowering increased intracranial pressure (ICP).4 One reason for this apparent disconnect is because the ideal timing of HTS administration and its concentration have not been determined.4 A meta-analysis previously determined no one prehospital fluid is superior to another in improving the outcomes of patients with severe TBI.5 However, none of the reviewed research investigated the continued use of HTS across an integrated system of care. This case report describes a patient with a severe TBI who received 3% HTS initiated in the prehospital setting with the infusion continued upon arrival at the trauma center using a system-wide integrated protocol.

Patient Care Alterations After Point-of-Care Laboratory Testing During Critical Care Transport.

OBJECTIVE: Point-of-care laboratory testing (POCT) is associated with a reduced time to testing results and critical decision making within emergency departments. POCT is an essential clinical assessment tool because laboratory data are used to support timely critical decisions regarding acute medical conditions onditions ; however, there is currently limited research to support the use of POCT in the critical care transport environment. Few studies have evaluated the changes in patient care that occur after POCT during critical care transport. This study aims to contribute to the limited data available correlating prehospital POCT and changes in patient care. METHODS: After institutional review board approval, a retrospective review of patients transported by a critical care transport team between October 1, 2013 and September 31, 2015 was completed. During the study period, 11,454 patients were transported, and 632 (5.51%) received POCT testing. RESULTS: Patient care changes were noted in 244 (38.6%) patient tests. The most frequent patient care alterations were ventilator settings (10.9%), electrolyte changes (10.4%), and unit bed upgrades (7.1%). POCT most frequently altered care for patients with post-cardiac arrest syndrome (64.7%), sepsis/septic shock (61.8%), diabetic ketoacidosis (54.5%), or pneumonia (49.3%). CONCLUSION: Patient care alterations occurred in 38.6% of patients undergoing POCT. Patient care was most frequently changed when patients were diagnosed with post-arrest, sepsis/septic shock, diabetic ketoacidosis, and pneumonia.

Busting top trauma myths. Exploring best practices for prehospital trauma care.

Evidence-based medicine will continually change the paradigm in which emergency medicine is practiced. Fifteen years ago tourniquets were a last resort and often considered a guaranteed way to lose a limb; today they are a gold standard in hemorrhage control. Believing in, and having practiced, medicine we later learn to be false doesn't make someone a bad provider, nor does it make them wrong. It simply means emergency medicine and EMS will continue to develop as a profession, and our body of evidence will continue to grow as we learn more about prehospital care. As we prepare to retire MAST, backboards and lidocaine, and realize the golden hour as a concept rather than a definitive 60 minutes, it's important to keep a critical eye out for the next intervention that truly will help patients during their prehospital care.

Surgical cricothyrotomies in prehospital care. Surgical airway placement is indicated when you cannot intubate or ventilate.

Managing the airway does not mean intubation, it means managing the airway. Allowing a patient to breathe on their own with appropriate positioning, bag-valve ventilation and blind insertion devices are all airway management options. The surgical cricothyrotomy is a rare and life-saving procedure when managing patients who are in a "can't intubate, can't ventilate" situation. These patients will die without aggressive and rapid intervention. While not all surgical cricothyrotomies provide a definitive airway, the needle cricothyrotomy is an ineffective means for ventilation and its use is discouraged. Understand the techniques used in your program and that are within your scope of practice as an EMS provider. Provide your patient the best opportunity for survival by knowing your program's surgical airway procedure thoroughly, and practice it regularly.

Aortic dissections and aneurysms. Prehospital care of these rare but life-threatening emergencies.

Aortic dissections and aneurysms are seen with low frequency and have high risk for deterioration during prehospital care. It is essential to include both dissections and aneurysms in your differential diagnoses whenever evaluating patients with chest or abdominal complaints. Often a good history is the best indication of one of these grave vascular emergencies. Consider thoracic aortic dissection in your differential diagnosis for any patient who complains of chest pain and aortic aneurysm in patients who have any sort of abdominal discomfort or syncope with an unknown etiology. When either is suspected transport rapidly to a facility with cardiothoracic and vascular surgery capability, and provide care that prepares you to manage the patient quickly should a rupture occur.

Critical transport decisions. In time-sensitive emergencies, every moment counts--choose wisely.

Time-sensitive emergencies require early recognition and rapid transport to a facility properly equipped to manage the patient's needs. When managing STEMI, cardiac arrest, suspected stroke, trauma or a severe sepsis patient, use your resources smartly. Manage the patient using all of your capabilities on scene and know the destination best prepared to manage the patient upon ED arrival. When it makes sense to extend transport time to take a patient to a proper facility, it is OK to do so. Considering air medical transport for patients as ground transports exceed 30 minutes is reasonable as long as the flight team provides transport more rapidly or brings additional care that will improve patient outcomes.

Preventing back injuries in EMS. What's the best approach to avoiding harm to providers?

Reducing back injuries requires a holistic approach and investment by all interested parties, from front-line staff to leadership and supporting agencies. As a provider, take the time to ensure you are lifting and moving equipment and patients in a manner that protects both the patient and you.
