Brain protection during neurosurgery.
The initial concept of brain protection during neurosurgery is based on research done in the 1970s-1980 which established the concept that by decreasing cerebral metabolic rate the brain could survive longer periods of ischemia. The first section of this chapter reviews some of this initial research that promoted the use of barbiturates for cerebral protection. The second section reviews curren...
متن کاملJunction during Combined Hyperkalemia, Hypoxia, and Acidosis
During ischemia, lidocaine or quinidine may prevent arrhythmias by blocking conduction without suppressing abnormal automaticity. The purpose of this study was to determine whether lidocaine or quinidine (5 Mg/ml) produced Purkinje fiber-papillary muscle block during superfusion in vitro with an altered Tyrode's solution containing some components of ischemia: 6 mM potassium, Po2 < 40, pH = 6.8...
متن کاملHypertonic Mannitol-Induced Hyperkalemia during Craniotomy
We experienced two cases of mannitol-induced hyperkalemia during craniotomy for ruptured aneurysms. Hyperkalemia was first diagnosed by peaked T wave on the ECG. Serum potassium concentration in each patient was approximately 2 mEq/l higher than the baseline value, reaching 6.0 and 5.7 mEq/l, respectively, at 2 hours after completion of infusion of 45 and 30 g mannitol, respectively. Although t...
متن کاملHigh-Resolution Angioscopic Imaging During Endovascular Neurosurgery
BACKGROUND Endoluminal optical imaging, or angioscopy, has not seen widespread application during neurointerventional procedures, largely as a result of the poor imaging resolution of existing angioscopes. Scanning fiber endoscopes (SFEs) are a novel endoscopic platform that allows high-resolution video imaging in an ultraminiature form factor that is compatible with currently used distal acces...
متن کاملThe sitting position in neurosurgery: a critical appraisal.
The potential for serious complications after venous air embolism and successful malpractice liability claims are the principle reasons for the dramatic decline in the use of the sitting position in neurosurgical practice. Although there have been several studies substantiating the relative safety compared with the prone or park bench positions, its use will continue to decline as neurosurgeons...
