What should be administered next to a patient with stage IV lung cancer, severe fatigue, nausea, vomiting, anorexia, weight loss, hypotension, mild dyspnea, and laboratory findings of anemia (low Hemoglobin), hyponatremia, and hyperkalemia, in addition to fluid resuscitation?

From the Guidelines

The next appropriate intervention for this patient, in addition to fluid resuscitation, would be hydrocortisone administration. This 67-year-old man with stage IV lung cancer presents with symptoms suggestive of adrenal insufficiency, including fatigue, nausea, vomiting, anorexia, weight loss, and hypotension. The laboratory findings of hyponatremia and hyperkalemia further support this diagnosis. Adrenal insufficiency can occur in patients with metastatic cancer due to either direct metastatic involvement of the adrenal glands or as a result of stopping exogenous steroids. Hydrocortisone is the treatment of choice for adrenal crisis, as it provides both glucocorticoid and mineralocorticoid effects, which will help correct the electrolyte abnormalities and improve blood pressure. While the patient is anemic, his hemoglobin of 10.5 g/dL is not critically low to explain his hypotension, making packed red cells less urgent. Similarly, inotropic support with dobutamine or dopamine would not address the underlying hormonal deficiency causing his symptoms and would be less appropriate as initial therapy compared to hydrocortisone.

The patient's symptoms of fatigue, nausea, vomiting, anorexia, and weight loss are also consistent with cancer cachexia, a condition characterized by weight loss, muscle atrophy, and fatigue, often seen in patients with advanced cancer 1. However, the primary concern in this case is the patient's hypotension and electrolyte abnormalities, which are more suggestive of adrenal insufficiency.

In terms of managing the patient's fatigue, the American Society of Clinical Oncology (ASCO) recommends exercise, cognitive behavioral therapy, and mindfulness-based programs as effective interventions for reducing cancer-related fatigue 1. However, these interventions are not immediately relevant to the patient's current acute presentation and would be more appropriate for long-term management.

Overall, the patient's clinical presentation and laboratory findings suggest adrenal insufficiency as the primary cause of his symptoms, and hydrocortisone administration is the most appropriate initial intervention.

From the FDA Drug Label

Restoration of Blood Pressure in Acute Hypotensive States Blood volume depletion should always be corrected as fully as possible before any vasopressor is administered.

The patient's blood pressure is 82/54 mm Hg, which is hypotensive. According to the drug label, blood volume depletion should be corrected as fully as possible before any vasopressor is administered. The patient has mildly dyspneic, scattered rhonchi and wheezes, and mucous membranes are slightly dry, indicating possible fluid depletion. Given the patient's hypotension and possible fluid depletion, the most appropriate next step would be to administer fluid resuscitation. However, among the provided options, A. Packed red cells may be considered to address the patient's anemia (Hemoglobin 10.5), but it is not directly addressing the hypotension. Dobutamine and Dopamine are not mentioned in the provided drug labels. Hydrocortisone is not indicated in this scenario based on the provided information. Since the labels provided are for norepinephrine, which is a vasopressor, and the patient is hypotensive, norepinephrine could be considered, but it is not among the options. The labels do mention that whole blood or plasma can be administered to increase blood volume, which is relevant to option A. Packed red cells. Considering the patient's low hemoglobin level (10.5) and weight loss, option A. Packed red cells might be a reasonable choice to address the patient's anemia, but it is essential to note that the primary concern is the patient's hypotension, which should be addressed with fluid resuscitation first. Based on the information provided and the drug labels, the best answer is A. Packed red cells 2 2.

From the Research

Patient's Condition

The patient is a 67-year-old man with stage IV lung cancer, extensive extra-pulmonary visceral metastases, and symptoms of fatigue, nausea, vomiting, anorexia, and weight loss. He has discontinued chemotherapy and is now hospitalized for treatment of dyspnea.

Laboratory Results and Physical Examination

• Hemoglobin: 10.5
• Serum sodium: 132
• Serum potassium: 5.2
• The patient is pale, mildly dyspneic, with a pulse rate of 78 per minute and blood pressure of 82/54 mm Hg.
• Mucous membranes are slightly dry, and cardiopulmonary examination reveals scattered rhonchi and wheezes.

Treatment Considerations

Given the patient's condition and laboratory results, the following treatment options should be considered:

• Fluid resuscitation is necessary due to the patient's hypotension and dry mucous membranes.
• The patient's low blood pressure and symptoms suggest the possibility of adrenal insufficiency, which can be life-threatening and requires prompt treatment 3, 4.
• Hydrocortisone administration is recommended for patients with adrenal insufficiency, especially in cases of adrenal crisis or septic shock 3, 5, 4.

Recommended Next Steps

In addition to fluid resuscitation, the administration of hydrocortisone should be considered due to the patient's symptoms and laboratory results, which may indicate adrenal insufficiency 3, 4.

• Key points to consider:
  • Adrenal insufficiency can be primary or secondary and requires prompt treatment with hydrocortisone 3.
  • The use of hydrocortisone in septic shock patients can result in immediate hemodynamic benefits 4.
  • There is no consensus on the diagnostic criteria for relative adrenal insufficiency, but hydrocortisone is often used in patients with septic shock and hypocortisolemia 4.
