ABSTRACT
This chapter describes the investigations, premedication, intravenous access and monitors of the cerebellopontine angle tumor. It also describes the induction, positioning, intravenous fluids and postoperative analgesia of the cerebellopontine angle tumor. The chapter explains the goals of anesthesia to prevent increases in intracranial pressure (ICP), to maintain hemodynamic stability and adequate cerebral perfusion pressure (CPP) and to facilitate rapid and smooth induction and emergence from anesthesia. It focuses on the drugs like mannitol, hypertonic saline, antiemetic prophylaxis, morphine and fentanyl bolus. The chapter discusses the intraoperative concerns like tight brain, risk of postural hypotension in sitting position and risk of venous air embolism (VAE) in sitting position. It also explains the postoperative concerns like pain, postoperative nausea and vomiting (PONV) and bulbar dysfunction. The chapter also discusses the patients with preexisting bulbar dysfunction may need mechanical ventilation and/or tracheostomy.
