Prehospital Mechanical Ventilation: An NAEMSP Position Statement and Resource Document.

Airway emergencies and respiratory failure frequently occur in the prehospital setting. Patients undergoing advanced airway management customarily receive manual ventilations. However, manual ventilation is associated with hypo- and hyperventilation, variable tidal volumes, and barotrauma, among other potential complications. Portable mechanical ventilators offer an important strategy for optimizing ventilation and mitigating ventilatory complications.EMS clinicians, including those performing emergency response as well as interfacility transports, should consider using mechanical ventilation after advanced airway insertion.Prehospital mechanical ventilation techniques, strategies, and parameters should be disease-specific and should mirror in-hospital best practices.EMS clinicians must receive training in the general principles of mechanical ventilation as well as detailed training in the operation of the specific system(s) used by the EMS agency.Patients undergoing mechanical ventilation must receive appropriate sedation and analgesia.

The Role of Tourniquet Placement in Management of a Patient With Status Epilepticus.

BACKGROUND: The global burden of seizure disorders is apparent and necessitates the effective management of patients with status epilepticus (SE). The goal of management is universally accepted as the prompt mitigation of seizure activity with appropriate supportive care. During management, patients may require intubation. In the process of endotracheal tube placement, patients are administered neuromuscular blockers and general anesthesia. Paralytic activity on the neuromuscular junction hinders the emergency physician's ability to effectively observe seizure activity. Moreover, little can be discerned about patient sedation levels for titration. Effective tourniquet placement may be used to separate a region of the body from general circulation, rendering distal tissues unaffected by neuromuscular blockade. CASE REPORT: A 73-year-old white woman presented to the emergency department with a stroke, and her condition generalized into diffuse tonic-clonic seizures. Concern for airway integrity warranted intubation with appropriate induction of paralysis and sedation. A tourniquet was placed proximal to the right knee and tightened until a dorsalis pedis pulse was no longer palpable. Computed tomography and computed tomography angiography of the head revealed no cerebrovascular event. After imaging, purposeful movements were noted in the right lower extremity distal to the tourniquet despite the initiation of standard dose post-intubation sedation with fentanyl (0.5 µg/kg/h) and propofol (20 µg/kg/min). No tonic-clonic activity was observed. With necessary up-titration, movements ceased. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: The observations made support the use of temporally limited tourniquet placement during paralytic administration to assess patient seizure status and sedation levels. Mindful tourniquet use in this manner permits a more effective sedation and management protocol for SE patients coming into the ED and may outweigh the minor risks associated with short-term hypoperfusion.

Rural ED transfers due to lack of radiology services.

PURPOSE: Our objectives were to determine the frequency of patient transfers to a tertiary care emergency department (Tertiary ED) due to a lack of radiology services in rural hospital EDs (Rural EDs), and examine the community and patient attributes that are associated with these transfers. METHODS: This was a retrospective chart review of patients transferred to a Tertiary ED from Rural EDs. Transfers excluded from the study included pediatric patients (age <18 years old) and patients transferred for trauma surgeon evaluation. Only those patients who were transferred for radiology services were included in the final analysis. RESULTS: Over a 12-month period, 1445 patients were transferred to the Tertiary ED with 73.8% (n = 1066) of this population being transferred from a Rural ED. Excluding 381 trauma and pediatric patients, 64.3% (n = 685) of patients were transferred from a Rural ED and were included in the study. Of these 685 transfers, 24.5% (n = 168) were determined to be due primarily to a lack of a radiology service. DISCUSSION: Lack of radiology services in Rural EDs leads to numerous patient transfers to the Tertiary ED each year. A disproportionate number of these transfer patients are African American. These transfers place additional financial and social burdens on patients and their families. This study discusses these findings and alternative diagnostic options (ie, telemedicine and ultrasound video transfer) to address the lack of radiology services available in Rural EDs. The use of these alternate diagnostic options will likely reduce the number of patient transfers to Tertiary EDs.
