Soft tissue hematoma of the neck due to thyroid rupture with unusual mechanism.

Highlights • Massive bleeding from the thyroid without direct neck trauma rarely causes airway compromise.• Physicians should regard possible thyroid gland rupture in patients with swelling of the neck or acute respiratory failure after direct/indirect trauma to the neck.• Airway management is the most important consideration in such patients with thyroid injury.

Predicting the return of spontaneous circulation after out-of-hospital cardiac arrest through blood gas analysis

Intr Several studies have investigated the factors associated with the return of spontaneous circulation (ROSC) in outof-hospital cardiac arrest (OHCA) cases. The most analyzed factor is pre-hospital resuscitation, such as an early phone call for the ambulance, bystander cardiopulmonary resuscitation (CPR), presentation with ventricular fibrillation, and medication. The blood gas parameters have not yet been reported as a predictive factor for ROSC.
