Intraoperative worries during a craniotomy typically centre on lowering Intra Cranial Pressure (ICP) and preventing unintentional cerebral ischemia. The cornerstone for achieving these objectives continues to be the maintenance of good systemic physiology. The two methods most frequently used to lower intraoperative ICP are mannitol and hyperventilation. An option to mannitol that is more physiological is hypertonic saline. However, the scant information that is now available does not conclusively demonstrate that it provides any benefit over mannitol for the circumstances of the brain after craniotomy. Regarding hyperventilation, a recent study in patients having surgery for supratentorial tumours demonstrated that mild hyperventilation at a PaCO2 of 32–35 mmHg significantly altered the subdural ICP and the surgeon's evaluation of brain relaxation.

The synaptic transmission mediated by gamma amino butyrate (GABA) and/or N-Methyl-Aspartate (NMDA) receptors appears to be inhibited by general anesthetics. Neumanaesthesia has developed from a clinical service addressing the needs of neurological patients to a scientific discipline that is also examining the fundamentals of the nervous system with benefits extending beyond anesthesia to nesciences generally. This is because GABA- and NMDA-mediated neuronal activity is essential for mammalian brain development and exposure to general anaesthetics could potentially interfere with normal brain maturation.

To protect the brain during surgery, anaesthetics have been used. Regarding the superiority of one agent over others, debate rages on. It has been asserted that inhalational medications provide more consistent protection than intravenous ones.

Interventional Neuroradiology

Cerebral aneurysms are being treated endovascular with cyanoacrylate glues, the Onyx liquid embolic system, and detachable coils on a regular basis. The medications nimodipine and intra-arterial papaverine are used to treat cerebral vasospasm. These procedures are best performed under general anesthesia. Endotracheal tubes have been replaced by laryngeal mask airways. Despite being utilised as a substitute for general anesthesia, simple sedation may cause the patient to move unintentionally and obstruct their airway at critical points in the procedure. The haemorrhagic and ischemic cerebral problems that could happen during an endovascular surgery may also require the attention of anesthesiologists providing treatment.

Anesthetics and Anesthesiology is an open access, Peer- reviewed Journal which will be dedicated to submission of manuscripts in the field of anaesthesia practice, airway management, anaesthetic administration, preoperative & postoperative considerations, pain management, Sedation, Invasive hypo sedation.

Authors can submit manuscripts through mail Id: anesthesiology@scholarsresjournal.com
