Abstract
The benefits of hypothermia for the treatment of subarachnoid hemorrhage (SAH) remain controversial. In 1999, we initiated brain hypothermia treatment (BHT) in the hyperacute phase to mitigate the evolution of early brain injury in patients with World Federation of Neurological Surgeons (WFNS) grade V SAH. In June 2014, we introduced endovascular cooling to maintain normothermia for seven days following the initial BHT period. Immediately after the decision to treat the sources of bleeding, cooling was initiated, with a target temperature of 33-34°C. Bleeding sources were extirpated primarily by clipping with decompressive craniectomy. Patients were rewarmed at a rate of ≤1°C/day after ≥48 hours of surface cooling. After being rewarmed to 36°C, temperatures were controlled with antipyretic (chronologically divided into groups A-C with 47, 46, and 46 patients, respectively) or endovascular (group D, 38 patients) cooling. Overall, 177 patients (median age, 62 [52-68] years; 94 [53.1%] women; onset-to-arrival time, 36 minutes [28-50]) were included. The median Glasgow Coma Scale (GCS) score upon admission was 4 (3-6). Median core body temperature was 36 (35.3-36.6)°C on arrival, 34.6 (34.0-35.3)°C on entering the operating room, 33.8 (33.4-34.3)°C upon starting the microsurgical or interventional radiology procedure, and 33.7 (33.3-34.2)°C upon admission to the intensive care unit. There were no significant differences in age, sex, GCS score, pupillary findings, location of bleeding sources, or treatment methods. There were 69 (39.0%) overall favorable outcomes (modified Rankin Scale score of 0-3) at 6 months and 11 (23.4%), 18 (39.1%), 17 (37.0%), and 23 (60.5%) in groups A-D, respectively (p = 0.0065). The outcomes of patients with WFNS grade V SAH improved over time. Herein, we report our experience using BHT for severe SAH through a narrative review.

Targeted Temperature Management for Severe Subarachnoid Hemorrhage Using Endovascular and Surface Cooling Systems: A Nonrandomized Interventional Study Using Historical Control. Neurosurgery 2022; 91:863-871.

Abstract
BACKGROUND Although targeted temperature management (TTM) may mitigate brain injury for severe subarachnoid hemorrhage (SAH), rebound fever correlates with poor outcomes. OBJECTIVE To study the effect of endovascular TTM after rewarming from initial surface cooling during a high-risk period for delayed cerebral ischemia. METHODS We studied patients with World Federation of Neurological Surgeons grade V SAH before and after the introduction of endovascular TTM. Both groups (36 patients each) were treated with TTM at 34 °C with conventional surface cooling immediately after SAH diagnosis, together with emergency aneurysm repair. When rewarmed to 36 °C, around 7 days later, the study group underwent TTM at 36 to 38 °C for 7 days with an endovascular cooling system. The control group was treated with antipyretics. RESULTS Sex, age, Glasgow Coma Scale score, modified Fisher computed tomography classification, aneurysm location, and treatment methods were not different between the study and control groups. Differences were detected in the incidence of fever >38 °C (13 vs 26 patients, P = .0021), duration of fever >38 °C (4.1 vs 18.8 hours, P = .0021), incidence of vasospasm-related cerebral infarction (17% vs 42%, P = .037), and the likelihood of excellent outcomes (0 and 1 on a modified Rankin Scale) at 6 months (42% vs 17%, P = .037). In endovascular TTM, shivering occurred more frequently in patients with better outcomes, requiring aggressive treatment to avoid fever. CONCLUSION Endovascular TTM at 36 to 38 °C after surface cooling was feasible and safely performed in patients with severe SAH. Combined TTM for 2 weeks was associated with a lower incidence of vasospasm-related infarction and may improve outcomes.

Abstract
Therapeutic hypothermia (TH) is considered a standard of care in the post-resuscitation phase of cardiac arrest. In experimental models of traumatic brain injury (TBI), TH was found to have neuroprotective properties. However, TH failed to demonstrate beneficial effects on neurological outcome in patients with TBI. The absence of benefits of TH uniformly applied in TBI patients should not question the use of TH as a second-tier therapy to treat elevated intracranial pressure. The management of all the practical aspects of TH is a key factor to avoid side effects and to optimize the potential benefit of TH in the treatment of intracranial hypertension. Induction of TH can be achieved with external surface cooling or with intra-vascular devices. The therapeutic target should be set at a 35°C using brain temperature as reference, and should be maintained at least during 48 hours and ideally over the entire period of elevated intracranial pressure. The control of the rewarming phase is crucial to avoid temperature overshooting and should not exceed 1°C/day. Besides its use in the management of intracranial hypertension, therapeutic cooling is also essential to treat hyperthermia in brain-injured patients. In this review, we will discuss the benefit-risk balance and practical aspects of therapeutic temperature management in TBI patients.

Abstract
Aneurysmal subarachnoid hemorrhage (SAH) remains a very prevalent challenge in neurosurgery associated with a high morbidity and mortality due to the lack of specific treatment modalities. The prognosis of SAH patients depends primarily on three factors: (i) the severity of the initial bleed, (ii) the endovascular or neurosurgical procedure to occlude the aneurysm and (iii) the occurrence of late sequelae, namely delayed ischemic neurological deficits due to cerebral vasospasm. While neurosurgeons and interventionalists have put significant efforts in minimizing periprocedural complications and a multitude of investigators have been devoted to the research on chronic vasospasm, the acute phase of SAH has not been studied in comparable detail. In various experimental studies during the past decade, hypothermia has been shown to reduce neuronal damage after ischemia, traumatic brain injury and other cerebrovascular diseases. Clinically, only some of these encouraging results could be reproduced. This review analyses results of studies on the effects of hypothermia on SAH with special respect to the acute phase in an experimental setting. Based on the available data, some considerations for the application of mild to moderate hypothermia in patients with subarachnoid hemorrhage are given.

Abstract
Therapeutic hypothermia (TH) is the intentional reduction of core body temperature to 32°C to 35°C, and is increasingly applied by intensivists for a variety of acute neurological injuries to achieve neuroprotection and reduction of elevated intracranial pressure. TH improves outcomes in comatose patients after a cardiac arrest with a shockable rhythm, but other off-label applications exist and are likely to increase in the future. This comprehensive review summarizes the physiology and cellular mechanism of action of TH, as well as different means of TH induction and maintenance with potential side effects. Indications of TH are critically reviewed by disease entity, as reported in the most recent literature, and evidence-based recommendations are provided.

Abstract
Recent experimental studies have demonstrated that oxidative stress has important roles in various neuronal conditions. Stroke and traumatic brain injury are also related to oxidative stress. However few studies prove the existence of free radicals in humans because they are difficult to measure. We recently developed a technique for free radical and oxidative stress monitoring using the ex vivo electron spin resonance (ESR) spin trapping method in patients with neuroemergency. Blood samples were collected by catheterization of the internal jugular bulb. The alkoxyl radical level was measured by ex vivo ESR spectrometry using 5,5-dimethyl-1-pyrroline-1-oxide (Dojin Chemical, Tokyo, Japan) as a spin trap. Electron spin response detection of the spin adduct was performed at room temperature using a JESREIX X-band spectrometer (JEOL, Tokyo, Japan). As a marker of reactive oxygen species, we also used the diacron-reactive oxygen metabolites test (d-ROM). This method is not invasive for patients, and it is technically easy to execute.Oxidative stress monitoring is useful and may prove valuable for clarifying the pathophysiology of neuroemergency diseases, which has long been hampered by technical difficulties in measuring and monitoring oxidative stress.

Abstract
During the past few decades, management of acute traumatic brain injury has advanced substantially on several fronts. Implementation of rapid transport systems and the advent of trauma centres, together with advances in emergency medicine, critical care medicine and trauma neurosurgery, have improved outcome following head injury. Technological advances made during the past years in the field of invasive neuromonitoring that provide real-time information on brain oxygenation may further improve outcome by enabling individualized therapies for intracranial hypertension. Furthermore, these recent technological advances will provide insights into the pathophysiological processes that are active in traumatic brain injury and a better understanding of the biochemical effects of specific therapeutic regimens.

Abstract
BACKGROUND Vasospasm caused by intracranial hypertension in head injury remains controversial. METHODS Between 1996 and 2004, we prospectively and consecutively performed conventional cerebral angiography for six patients with head injuries who showed persistent intracranial hypertension (over 20 mm Hg for longer than 5 days) despite performing various treatments for intracranial hypertension. RESULTS All subjects had a minor hemorrhage at admission, classified as Fisher group 2. Five of the six patients had angiographically confirmed vasospasm, and one of them later developed a cerebral infarction. Four of the five subjects who exhibited cerebral vasospasm had undergone hypothermic therapy to control the intracranial hypertension. CONCLUSION Our results suggest that persistent intracranial hypertension that is treated by hypothermic therapy may be related to late phase cerebral vasospasm.

Abstract
Induced hypothermia to treat various neurologic emergencies, which had initially been introduced into clinical practice in the 1940s and 1950s, had become obsolete by the 1980s. In the early 1990s, however, it made a comeback in the treatment of severe traumatic brain injury. The success of mild hypothermia led to the broadening of its application to many other neurologic emergencies. We sought to summarize recent developments in mild hypothermia, as well as its therapeutic potential and limitations. Mild hypothermia has been applied with varying degrees of success in many neurologic emergencies, including traumatic brain injury, spinal cord injury, ischemic stroke, subarachnoid hemorrhage, out-of-hospital cardiopulmonary arrest, hepatic encephalopathy, perinatal asphyxia (hypoxic-anoxic encephalopathy), and infantile viral encephalopathy. At present, the efficacy and safety of mild hypothermia remain unproved. Although the preliminary clinical studies have shown that mild hypothermia can be a feasible and relatively safe treatment, multicenter randomized, controlled trials are warranted to define the indications for induced hypothermia in an evidence-based fashion.
