ReviewRole of anaesthesia in neurosurgical enhanced recovery programmes.
The application of Enhanced Recovery After Surgery (ERAS) in neurosurgical practice is a relatively new concept. A limited number of studies involving ERAS protocols within neurosurgery, specifically for elective craniotomy, have been published, contrary to the ERAS spine surgery pathways that are now promoted by numerous national and international dedicated surgical societies and hospitals. In this review, we want to present the patient surgical journey from an anaesthesia perspective through the key components that can be included in the ERAS pathways for neurosurgical procedures, both craniotomies and major spine surgery.

ReviewMechanical ventilation in neurocritical care setting: A clinical approach.
Neuropatients often require invasive mechanical ventilation (MV). Ideal ventilator settings and respiratory targets in neuro patients are unclear. Current knowledge suggests maintaining protective tidal volumes of 6-8 ml/kg of predicted body weight in neuropatients. ⋯ Additionally, the weaning process from MV is particularly challenging in these patients who cannot control the brain respiratory patterns and protect airways from aspiration. Indeed, extubation failure in neuropatients is very high, while tracheostomy is needed in one-third of the patients. The aim of this manuscript is to review and describe the current management of invasive MV, weaning, and tracheostomy for the main four subpopulations of neuro patients: traumatic brain injury, acute ischemic stroke, subarachnoid hemorrhage, and intracerebral hemorrhage.

ReviewChallenges and pitfalls in anesthesia for electroconvulsive therapy.
Electroconvulsive therapy (ECT) refers to the application of electricity to the patients' scalp to treat psychiatric disorders, most notably, treatment-resistant depression. It is a safe, effective, and evidence-based therapy that is performed with general anesthesia. ⋯ For the anesthesiologist, ECT is associated with the challenges and pitfalls that are related to informed consent, social acceptance of ECT, airway management (especially in COVID-19 patients), and the interaction between ventilation and anesthetics from one viewpoint, and seizure induction and maintenance from another. The exact mode of action of the therapy is as unknown as the optimal choice or combination of anesthetics used.

ReviewNoninvasive neuromonitoring in the operating room and its role in the prevention of delirium.
Delirium is a frequent and serious complication after surgery. It has a variable incidence between 20% and 40% with the highest incidence in elderly people undergoing major or cardiac surgery. The development of postoperative delirium (POD) is associated with increased hospital stay lengths, morbidity, the need for home care, and mortality. ⋯ Another noninvasive monitoring technique is NIRS for cerebral tissue hypoxia detection by measuring regional oxygen saturation. The reduction of this parameter does not seem to be associated with the development of POD but with postoperative cognitive dysfunction. There are few studies in the literature and with conflicting results on the use of the pupillometer and transcranial Doppler in predicting the development of postoperative delirium.
