[Anesthesiologic problems in candidates for delayed surgery].
In preparing and maintaining a proper anaesthetic plan in the patient with subarachnoid haemorrhage undergoing delayed surgery, various concerns occur to the anaesthesist and the intensivist. These problems are related to the intracranic pathology but also to the structural, biochemical and functional changes occurring in a lot of organs and systems. Aim of anaesthetic approach is a correct preoperative evaluation and the maintenance of intracranic and systemic homeostasis. Systemically it is frequent the evidence of electrocardiographic abnormalities, due in same instances to myocardial hypoperfusion, of respiratory dysfunctions, of idroelettrolitic and metabolic changes leading to hypovolemia, hyponatremia and hypokalemia, and of coagulation disorders. With regards to the cerebral homeostasis, it is imperative to prevent rebleeding and vasospasm and the related neurologic damage. It is important the preoperative correction of the systemic dysfunctions, the prevention of the secondary neurologic damage, the stabilization of hemodynamic responses to various noxious stimuli, the provision of a good surgical field, and the achievement of a stable recovery; all these with the help of a proper clinical and instrumental monitoring.
