Regional Anaesthesia for Neurosurgery

During neurosurgery procedures it is vital to assure optimal cerebral perfusion and oxygenation. Despite physiological autoregulation of brain perfusion, maintaining hemodynamic stability and good oxygenation during anesthesia is vital for success. General anesthesia with mechanical ventilation and current drugs provide excellent hemodynamic condition and it is the first choice for most neurosurgery procedures. However, sometimes it is very hard to avoid brief increase or decrease in blood pressure especially during period of intense pain, or without pain stimulation. This could be detrimental for patients presented with high intracranial pressure and brain edema. Modifying anesthesia depth or treatment with vasoactive drugs usually is needed to overcome such circumstances. On the other hand it is important to wake the patients quickly after anesthesia for neurological exam. That is why regional anesthesia of scalp and spine could show beneficial effects by decreasing pain stimuli and hemodynamic variability with sparing effect of anesthetics drugs. Also regional techniques provide excellent postoperative pain relief, especially after spinal surgery.
