Thyroid gland hemorrhage after blunt neck trauma: case report and review of the literature.

Background: Thyroid hemorrhage is considered to be an uncommon complication following blunt trauma to the neck. This condition is potentially life-threatening due to airway compression and may therefore require emergency airway management and surgical intervention in some cases.

Case Presentation: We present the case of a 52-year-old woman who experienced a traumatic thyroid gland rupture (right lobe) with subsequent active arterial bleeding from branches of the inferior thyroid artery.

The effective concentration 50 (EC50) for propofol with 70% xenon versus 70% nitrous oxide.

Background: Xenon anesthesia has many favorable properties, such as pain modulation and organ protection. However, due to its MAC of 70%, it cannot be used as a sole anesthetic. We estimated the amount of propofol required to supplement xenon to produce adequate anesthesia in 50% and 95% of patients in comparison with nitrous oxide.
