Iii. To avoid fluid overload, as well as hypoglycemia, concentrated glucose infusions delivered through a central line may be needed. Glucose levels should be monitored closely and rapid glucose boluses avoided. Infusions should be weaned slowly to avoid rebound hypoglycemia. C. Gastrointestinal effects. Feeding should be withheld until blood pressure is stable, active bowel sounds are audible, and stools are negative for blood (see chap. 27). D. Hematologic abnormalities (see chaps. 42-47). Coagulation profile should be monitored with partial thromboplastin time (ptt) and prothrombin time (pt), fibrinogen, and platelets. Abnormalities may need to be corrected with fresh frozen plasma, cryoprecipitate, and/or platelet infusions. E. Liver function should be monitored with measurement of transaminases (alt, ast), dotting (pt, ptt, and fibrinogen), albumin, bilirubin, and ammonia. Levels of drugs that are metabolized or eliminated through the liver must be monitored. F. Lung (see chaps.

Patient is hemodynamically stable with systolic blood pressure > 100 mmhg. T e ventilator is adjusted to normocapnea (paco2 35–45 mmhg). T e patient is preoxygenated or 10 minutes with 100% fio2 (pao2 > 200 mmhg). Ensure the patient maintains oxygenation with a peep setting o 5 cm h 2o. T e ventilator is disconnected. Oxygen is provided via insu ation catheter at 6 l/min or via -piece with a cpap valve at 10 cm h 2o. Spontaneous respirations must be absent. At 10 minutes, an arterial blood gas (abg) is drawn and the patient reconnected to the ventilator. I the paco2 on the abg is > 60 mm h 2o or the paco2 increased > 20 mm h 2o, the apnea test is positive. I the apnea test is aborted, then other ancillary tests should be used to con rm brain death. I the apnea test is inconclusive, xt what ancillary tests should be obtained to urther examine brain death?. 23 t e use o ancillary testing in the con ormation o brain death was introduced in the medical literature to assist examiners when either the apnea test could not be perormed or there were unreliable ndings on the neurologic examination.

The α-interferons are used in the treatment of cancer. Interferon enhances the immune system’s attack on cancer cells, can decrease new blood vessel formation, and can augment expression of antigen on tumor cell surfaces. Interferon has shown clinical activity in the treatment of melanoma, kidney cancer, kaposi sarcoma, and cml and cll. Unfortunately, interferon is not well tolerated by patients because it causes a flu-like syndrome that consists of fevers and chills. Depression, malaise, and fatigue are other side effects. Premedication with acetaminophen helps alleviate the flu-like symptoms, which decrease with chronic administration. »» aldesleukin aldesleukin, which is a human recombinant interleukin-2 (il-2), is a lymphokine that promotes b- and t-cell proliferation and triggers a cytokine cascade to attack the tumor. Aldesleukin has shown clinical activity in the treatment of kidney cancer and melanoma. Side effects of il-2 vary by dose and route. Iv highdose il-2 causes a drug-induced shock-like picture. Patients may develop hypotension despite aggressive iv hydration. Patients develop a red, itchy skin. Liver and kidney function tests change. Via immune complex formation in the kidneys, fluid and electrolyte imbalances occur. And high fevers occur while receiving scheduled acetaminophen and nonsteroidal anti-inflammatory agents. Severe rigors and chills may require symptom control. All the side effects reverse within 24 hours of stopping the drug. The 1306  section 16  |  oncologic disorders toxicity profile is much less with subcutaneous administration.

Steroids reverse all the symptoms and the antitumor effect even with topical administration. The itching, red skin may be treated with topical creams and antihistamines. »» peginterferon α-2b sylatron is a covalent conjugate of recombinant α-2b interferon with monomethoxy polyethylene glycol (peg). The mechanism of cytotoxicity in patients with melanoma is unknown. This agent is specifically indicated for the adjuvant treatment of melanoma with microscopic or gross nodal involvement up to 84 days after definitive surgical resection (including complete lymphadenectomy). Adverse effects include fatigue, increased liver enzymes, pyrexia, headache, anorexia, myalgia, nausea, chills, and pain at the injection site. 31 »» sipuleucel-t sipuleucel-t is a novel autologous cellular immunotherapy approved for the treatment of asymptomatic or minimally symptomatic metastatic hormone refractory prostate cancer. Sipuleucel-t is designed to induce an immune response targeted at prostatic acid phosphatase (pap), which is an antigen expressed in greater than 95% of prostate cancers. Patients receiving sipuleucelt undergo leukapheresis to collect their own antigen-presenting cells. These cells are then sent to a manufacturing facility and cultured with a recombinant antigen (pap-gm-csf, composed of pap and gm-csf, an immune cell activator). The cellular product, which is made specifically for each patient, is then delivered to the patient’s clinic and infused intravenously into the patient on day 3 or 4.
