Introduction Hyperosmolar therapy with mannitol or hypertonic saline (HTS) is the primary medical management strategy for elevated intracranial pressure (ICP). La solución salina isoncótica-hipertónica [NaCl 7,2%/ HES (/0,5) 6%] y manitol (20%), en dosis única con carga osmolar equivalente, fueron efectivos y . isoncótica hipertônica versus manitol (20%) durante neuroanestesia eletiva manitol versus solución isoncótica hipertónica (SIH), durante la neurocirugía.

Th e independent effi cacy of HTS is summar-ized by Mortazavi and colleagues, who report soluciion ICP reduction in the vast majority of investigations and clinical scenarios .
Dose-response relationship of mannitol and intracranial pressure: These fi ndings have prompted calls for large-scale comparator trials of mannitol and HTS, but such trials would only be necessary if the designation of mannitol as the gold standard is appropriate and if current evidence suggests its therapeutic equipoise with HTS.
Influencia del amortiguamiento en manitol sobre la fuerza del acido borico Documents. En el presente articulo mostramos la evidencia actual sooucion soporta a la SSH y al manitol y cual se considera la mejor opcion como terapia medica en el tratamiento de la HIC. No statistically significant differences were found in terms of cerebral relaxation, hence the conclusion that single doses with equivalent osmolar load of either of these agents are effective and safe for general cerebral relaxation during elective neurosurgical procedures under general anaesthesia.
Observational studies have shown a relationship between PbtO 2 reduction and poor outcomes 80,81 and suggest that therapy targeted on maintaining PbtO hipertonicx may improve clinical outcomes. One theory soluciln that they reduce water content in the brain, and a second theory is that they reduce viscosity and cerebrovascular resistance, giving rise to compensatory vasoconstriction and reduced CBV.
The Brain Trauma Foundation in its management guidelines for TBI is clear in stating that hypotension must be avoided because it is an isolated parameter of poor prognosis. Th e fi rst, a Cochrane review , identifi es four studies supporting the effi cacy of mannitol in treating IH. Vasogenic oedema is usually the result of increased capillary permeability due to breakdown of the BBB from trauma, tumours, abscesses, white matter usually being the most affected.
Safety of hypertonic hyperoncotic solutions-a survey from Austria. Hypertonic saline versus mannitol for the treatment of elevated intracranial pressure: Confl icts of interestThe author declares that he has no competing interests. Several factors need to be considered when mannitol is started, including hypotension, sepsis, and the use of other nephrotoxic agents given the additional risk of lowering the threshold of the toxic maniotl accumulated in the patient.
Moreover, there is the advantage of being able to use Manitoll successfully again after mannitol has failed. However, 9 comparative studies, 7 of which were randomized prospective controlled studies, showed that HTS was better at controlling ICP than mannitol. The study included 40 elective patients, the majority ASA-III, taken to surgery for supratentorial tumours, posterior fossa procedures, AVM and aneurisms, with and without subarachnoid haemorrhage.

P Visweswaran 1 Estimated H-index: Enhancement of cerebral blood flow using systemic hypertonic saline therapy improves outcome in patients with poor-grade spontaneous subarachnoid hemorrhage. Effects of hypertonic saline hydroxyethyl starch solution and mannitol in patients with increased intracranial pressure after stroke.
There are few studies comparing mannitol and HTS in the pure setting of cerebral relaxation in tumours. Over the past 25 years, however, hypertonic saline HTS has become a progressively more common alternative to mannitol, and several recent studies have suggested its relative superiority.
Generally, intracerebral peritumoral oedema is vasogenic. De Vivo et al. Abel Wakai 15 Estimated H-index: Of the 36, 12 compared mannitol with HTS: High-osmolality saline in neurocritical care systematic review and meta-analysis. They showed a low potential of complications with the use of HHS in the clinical setting during almost one decade.
No ICP rebound effect was observed in any of the trials during their respective study periods. After inducing haematomas, they measured ICP, cerebral perfusion pressure, cerebral oxygen extraction and oxygen consumption, as well as CBF in regions close to the haematoma and distant to it.

Out-of-hospital hypertonic resuscitation following severe traumatic brain injury: Next, I review recent comparative effi cacy data for HTS versus mannitol. An elevated osmolar gap correlates with mannitol accumulation, and a low level ensures mannitol clearance. ConclusionsMannitol is often considered the gold-standard therapy for medical management of IH, primarily because of its long history.
Still under the continuous HTS infusion, h after the episode, the brain CT scan manitkl both patients revealed extension of the cerebral oedema, suggesting a rebound effect similar to that already described with mannitol. Research studies that have influenced practice of neuroanesthesiology in recent years: We review the efficacy data for HTS compared with mannitol in terms of clinical considerations.

They recommend that HTS is a safe alternative to mannitol in brain size reduction in patients with and without subarachnoid haemorrhage, in particular if they are hipertonixa unstable.
They asked about the agent used most frequently, dose, and follow-up method.
Medical and neurological complications of ischemic stroke: These two conditions worsen neurological outcomes and are the major cause of mortality in neurological patients. Hypertonic saline resuscitation attenuates neutrophil lung sequestration and transmigration by diminishing leukocyte-endothelial interactions in a two-hit model of hemorrhagic shock and infection.
Mannitol versus hypertonic saline solution in neuroanaesthesia
Several theories have been proposed. Effect of mannitol and hypertonic saline on cerebral oxygenation in patients with severe traumatic brain injury and refractory intracranial hypertension. Cerebral blood flow augmentation in patients with severe subarachnoid haemorrhage. Many of the problems have not been elucidated yet, hence the need for additional research in order to arrive at a definitive conclusion about the superiority of these hyperosmolar agents and for protocols with adequate doses and concentrations of these agents as first-line therapy to control intracranial hypertension.
