The scoping review by Nicolò Marchesini and colleagues about the use of hyperosmolar therapies (HTs) in patients with traumatic brain injury (TBI) points out a significant gap in scientific literature regarding this topic. Although there are few high-quality recommendations, it is important to provide care under certain physiologic parameters. Through this letter we comment on the importance of guidelines to administer and monitor the use of HTs in the Neuro-ICU.
