Preoperative Preparation in Cancer Disease

Backgrounds: Patients may be healthy or desperately ill with nutritional, neurologic, metabolic, endocrinologic, electrolyte, cardiac, pulmonary, renal, hepatic, hematologic, or pharmacologic disabilities, requires correction.Thus, requires evaluation of all systems.Hypercalcemia , uric acid nephropathy, hyponatremia, nausea, vomiting, anorexia and cachexia, fever, tumor-induced hypoglycemia, intracranial metastases, peripheral nerve or spinal cord disorders, meningeal carcinomatosis, toxic neuropathies, and paraneoplastic neurologic syndromes may seen.Material and Method: Nausea and vomiting are the most common side effects of chemotherapy and radiation. Ondansetron, droperidol, and metoclopramide control nausea. TCA potentiate the analgesic effects of opioids.Result: Hepatic or renal dysfunction influence the choice of anesthetic drugs. Prolonged response to Sch is seen in patients being treated with alkylating chemotherapeutic drugs. Aseptic technique is important because immunosuppression occurs with most chemotherapeutic agents. Immunosuppression produced by anesthesia, surgical stimulation, or blood transfusion could exert effects on the patient's subsequent response to cancer. Because of suppression of the immune response, some anesthetic drugs may assist in tumor growth or enhance aggregation of some cancer proteins.Conclusion: Patients may have life-threatening airway difficulties and upper airway obstruction with head, neck, and chest tumors. Required to assess potential difficulties that may arise in securing the airway. Awake fiberoptic intubation is the gold standard. In some patients, tracheostomy may be indicated.Preoperative evaluation includes a review of potential side effects related to chemotherapy. Placement of intravenous catheters in the arm at risk of lymphedema is avoided because exacerbation of lymphedema and susceptibility to infection. It is necessary to protect that arm from compression and heat exposure. Bone pain and pathologic fractures is noted in regional anesthesia and when positioning patients. Selection of anesthetic drugs, techniques, and special monitoring is influenced more by the planned surgical procedure than by the presence of cancer.
