Background: Mannitol and hypertonic saline are the most frequently used hyperosmolar agents to treat cerebral edema resulting from acute brain injury. However, there are several issues with using hyperosmolar therapies. Here, we focus on the potential adverse effects of hyperosmolar therapies and practical tips to overcome these issues in the neurointensive care unit.
Current Concepts: Among the hyperosmolar agents used, mannitol may decrease intravascular volume and pose a potential risk of acute kidney injury for patients. Complications associated with using hypertonic saline include the risk of central pontine myelinolysis, coagulopathy, electrolyte imbalances, metabolic acidosis, and pulmonary edema. In addition, prolonged use of hypertonic saline increases the risk of hyperchloremic metabolic acidosis, which may be overcome with the concomitant use of sodium acetate.
Discussion and Conclusion: Several laboratory variables were monitored in the neurointensive care unit to limit and possibly detect early complications related to hyperosmolar therapies. When using hyperosmolar agents, including mannitol and hypertonic saline, for therapeutic purposes in patients with cerebral edema, determining whether to use peripheral or central lines and determining the appropriate rate and infusion dose can minimize their adverse effects. Clinicians need to be aware of the potential adverse events of administering hyperosmolar agents.
