Postoperative care of neurosurgical patients: general principles

The primary aim of care immediately after neurosurgery is to detect and prevent neurological deterioration while supporting systemic and neurological homoeostasis. Surgical-, anaesthetic- or disease- related factors may contribute to a slow return or failure to regain a patient's preoperative status. A period of specific monitoring and observation by nursing and medical staff accustomed to neurosurgical and neurocritical care procedures should be planned for the immediate postoperative period. In many neurosurgical centres the period of postoperative observation may be relatively short (e.g. limited uneventful craniotomies); however, if complicating factors such as cerebral oedema, intracranial haemorrhage, seizures or significant premorbid conditions are present, a period of higher dependency care over several days may be anticipated. In common with all postoperative care safe management of the airway, weaning of ventilatory support, control of circulation and fluid balance, feeding, sedation and analgesia are the mainstays of care. Meticulous attention to each of these is essential in the post neurosurgical patient as poor management can profoundly affect neurological outcome. Thus a robust perioperative plan is mandatory for management of the airway, control of blood pressure, and to ensure continuation of preoperative medication. Furthermore, the plan may entail elective creation of tracheostomy and percutaneous endoscopic gastrostomy. The early postoperative neurosurgical patient continues to require a high degree of clinical vigilance.
