Patients with hypertensive crises may require immediate reduction in elevated blood pressure to prevent and arrest progressive end-organ damage. The best clinical setting in which to achieve this blood pressure control is in the intensive care unit, with the use of titratable intravenous hypotensive agents.
Implementation of therapeutic hypothermia has its advantages, although complications are associated with its use. Shivering is a common complication that occurs during the induction and rewarming phases of therapeutic hypothermia. Strategies for preventing and managing shivering vary across protocols.
Non-shivering thermogenesis is the production of metabolic heat without shivering, and is caused by diet and muscle activity during movement. Non-shivering thermogenesis is the primary pathway for heat production in mammals and birds, and is more efficient than shivering thermogenesis.Shivering is only used as a last resort, once an individual has exhausted the ability to generate metabolic heat.hivering thermogenesis is used to heat the body when it becomes too cold. Shivering is usually triggered by exposure to cold environmental temperatures, but the temperature set point that triggers shivering varies among species and individuals.
