WebMannitol as a hyperosmolar agent was introduced in 1961 and became the agent of choice to manage ICP. 1,4 In the 1990s, hypertonic sodium chloride (e.g., 3%, 5%, 23.4%) was introduced as a hyperosmolar agent, and its use to manage ICP has increased while mannitol use has decreased. 1,5 Webwww.cochranelibrary.com
WebThe use of hypertonic solutions (2%, 3% and 23.4% sodium chloride) were initially used for in-the-field resuscitation of patients with multi-system trauma, and later for treatment of increased ICP due to conditions such as brain tumors or isolated traumatic brain injury. Recently, hypertonic solutions have been used as osmotic therapy for brain WebAbstract Hypertonic saline (HTS) is a commonly administered agent for intracranial pressure (ICP) control in traumatic brain injury (TBI). ... Exam- ples of hyperosmolar therapy include solutions such as mannitol and hypertonic saline (HTS). The goal of this therapy in TBI is to decrease cerebral edema and prevent/reduce secondary brain injury ...
WebNov 1, 2024 · Hypertonic saline decreases the viscosity of respiratory mucus by multiple mechanisms, which include osmotic hydration of the mucus layer (i.e. attracting water into it) and disruption of mucus proteins It is also irritant, which promotes cough Disadvantages It's irritant, which the patients will not appreciate. WebIf a cell is placed in a hypertonic solution, there will be a net flow of water out of the cell, and the cell will lose volume. A solution will be hypertonic to a cell if its solute concentration …
WebJun 22, 2024 · To achieve the desired osmotic gradient and reduce ICP, most protocols use the approach of targeting a level of serum sodium of 145-155 mmol/L. Careful monitoring of serum sodium levels every 4-6 …
