Quality of Recovery Awake Versus Asleep Craniotomy

Awake craniotomy (AC) is an anesthetic and surgical technique commonly used to resect tumors involving or adjacent to the eloquent or motor cortices, those portions of the brain that are responsible for language and motor skills, respectively. By mapping those areas of the brain that are necessary for such functions, the neurosurgeon is able to avoid resection of cortical tissue that might compromise the patient's abilities to speak or move, hence preserving neurologic function. AC is often accomplished by direct cortical stimulation or inhibition, while maintaining the patient's ability to interact with the operative team. The anesthetic technique often involves a regional (scalp) block combined with intraoperative intravenous mild sedation. In some reported instances of AC, no cortical mapping is performed, and the technique is performed solely because it is thought that AC leads to a better recovery profile (less pain, better neurologic outcome, and shorter hospital stay) than craniotomy performed under general anesthesia. The Quality of Recovery Score (QoR-40) is a validated, multi-parameter instrument that has been used in various postoperative populations to assess the overall satisfaction and well-being of patients having undergone anesthesia and surgery. Leslie et al. have reported that the QoR-40 is a valid tool in assessing neurosurgical patients, but a direct comparison between AC patients and general anesthesia craniotomy (GAC) patients using this tool has never been performed. AC may also be associated with better 30 and 90 day multi-parameter outcomes than GAC. The well-validated Acute Short Form (SF-12) health survey, an abbreviated version of the SF-36, consists of 12 items. It measures two domains, including mental and physical component summaries (mental component summary and physical composite score, respectively). Hypothesis: Awake craniotomy for tumor resection is associated with a better multi-parameter quality of recovery in the immediate postoperative period, and better 30 and 90 day quality of life outcomes, than craniotomy performed under general anesthesia.

Proton Beam Radiotherapy for Medulloblastoma and Pineoblastoma

There are two types of external radiation treatments (proton beam and photon beam). As part of the participant's treatment, they will receive radiation to the entire central nervous system (CNS); this is known as craniospinal irradiation (CSI). In the past, photon radiation therapy has been used for CSI. In this study we will be examining the effects of proton beam radiation therapy. Studies have suggested that this kind of radiation can cause less damage to normal tissue than photon radiation therapy. The physical characteristics of proton beam radiation let the doctor safely deliver the amount of radiation delivered to the tumor that is normally delivered through standard therapy but spare more normal tissue in the process.

Start: April 2010

Proton Radiotherapy for Pediatric Brain Tumors Requiring Partial Brain Irradiation

Some patients with brain tumors receive standard radiation to help prevent tumor growth. Although standard radiation kills tumor cells, it can also damage normal tissue in the process and lead to more side effects. This research study is looking at a different form of radiation called proton radiotherapy which helps spare normal tissues while delivering radiation to the tumor or tumor bed. Proton techniques irradiate 2-3 times less normal tissue then standard radiation. This therapy has been used in treatment of other cancers and information from those other research studies suggests that this therapy may help better target brain tumors then standard radiation.

Confocal Laser Endomicroscopy for Brain Tumors

The prognosis of glioblastoma patients highly depends on resection extent. Various strategies have been introduced to overcome the dilemma of intraoperative tumor identification. In gastroenterology, confocal laser endomicroscopy (CLE) allows precise differentiation of tumor tissue from surrounding mucosa in various diseases. Combining high-definition white light endoscopy with CLE significantly increases sensitivity and specificity compared with the sole application of high-definition white light endoscopy. CLE was recently introduced to neurosurgical applications. Although still in an early stage of clinical application, this technique has proven to be capable of differentiating various tumor entities in animal models as well as human tissue samples. CLE allows visualization of the underlying tissue on a microscopic scale, receiving information on the microstructure as well as cellular components. However, the clinical importance of this technique for its application in neurosurgery will be demonstrated in this clinical trial.

Effects of Intraoperative GDFT on the Postoperative Brain Edema

Whether a fluid protocol aiming for cardiac output augmentation or fluid restriction is favorable to post-craniotomy outcomes such as brain edema remains uncertain. To our knowledge, there has been no extensive and quantitative analysis of brain edema following SVV-based GDFT in neurosurgical patients with malignant supratentorial glioma. So the study aima to observe the effect of the stroke volume variation-based GDFT on the postoperative brain edema and decrease the incidence of postoperative complications in neurosurgical patients with malignant supratentorial gliomas.

Effect of Dexmedetomidine on Brain Homeostasis and Neurocognitive Outcome

Brain tumor surgery is commonly associated with different degrees of preoperative intracranial hypertension and surrounding tumor edema, elicited by tumor underlying pathophysiology. During craniotomy for brain tumor resection maintenance of hemodynamic stability and intracranial homoeostasis is of paramount importance. Disordered hemodynamics or adverse stress may activate the immune inflammation or neuroendocrine responses and lead to a surge of inflammatory mediators and stress hormones, which are implicated in secondary brain insults. Adverse physiological responses caused by intraoperative disordered hemodynamics or surgery-related damage, may lead to some secondary brain injury (such as cerebral edema or cerebral hemorrhage), aggravating damage to brain tissue and affecting the recovery from anesthesia, cognition and prognosis in patients. Prevention of secondary brain injury is a key-endpoint to improve clinical outcomes in glioma patients undergoing craniotomy. Alpha2-adrenoceptor agonists have been widely used for sedation, analgesia and anti-sympathetic actions for many years, but the definite evidence of their potential use as neuroprotectants has so far been confined to animal studies, yet the findings are inconsistent. Dexmedetomidine (DEX) has been demonstrated to be a new type a2 adrenergic receptor (a2-AR) agonist, which can selectively bind with the a1 and a2 adrenergic receptor, and playing a dual role by restraining the activity of sympathetic nervous and stimulating the vagus nerve. Dexmedetomidine (DEX) also plays an important role in in inhibiting inflammatory and neuroendocrine responses. Animal experiments showed that the right must have a dexmedetomidine neuro-protective effect. However, the brain-protective effect of dexmedetomidine in anesthesia of craniotomy resection of glioma has not been reported. Thus, the aim of this study was to explore the effect of dexmedetomidine on perioperative brain protection, as well as cerebral oxygenation and metabolic status aiming to provide a basis for clinical rational drug use in patients undergoing craniotomy resection of glioma.
