Anesthesia for meningioma surgery

Patients receiving treatment for a meningioma require anesthesia when undergoing open craniotomy and, in some cases, during preoperative tumor embolization and radiosurgery. Adequate anesthesia management is integral to patients' perioperative care, which consists of the three phases of preoperative assessment and optimization, intraoperative care, and postoperative recovery. The preoperative anesthesia evaluation focusses on the cardiorespiratory and neurologic systems, as well as the airway, but also extends to ensure the optimal treatment of significant comorbidities before surgical intervention. The goals of intraoperative care are maintenance of brain physiology, facilitating surgery, and correcting any adverse effects of surgery and underlying pathology to preserve general patient homeostasis. This requires adequate intraoperative patient monitoring, cardiorespiratory support, management of infusion therapy, and application of knowledge about the effects of anesthetic agents on brain physiology. The anesthesiologist's responsibilities for patient care extend well into the postoperative recovery period, with a focus on pain control, prevention, and treatment of postoperative nausea and vomiting (PONV), and, in some patients, intensive care therapy.
