Nursing 22: Oncology (Oncological Emergencies)

Oncological Emergencies

These are medical situations that take priority over anything else going on. They include:
- Sepsis
- DIC
- SIADH
- Spinal Cord Compression
- Superior vena Cava Syndrome
- Tumor Lysis Syndrome
- Hypercalcemia (as well as Hypocalcemia)
- Intractable Pain

Sepsis

This is an oncological emergency where a patient goes into septic shock. With this, you must obtain a blood and urine culture FIRST, then give an antibiotic.
You are looking for a band shift to the left

Disseminated Intravascular Coagulation (DIC)

This is an oncological emergency caused by a gram negative infection (like from Raw Fruits and veggies)
- It is an abnormal clot formation in microthrombi, leading to mulit organ system failure and death

DIC Signs and Symptoms

These include
- Peechia, echymosis, bleeding, hemorrhage, oliguria, convulsion
- PT & PTT - PROLONGED
- Platelets and Fibrinogen - DECREASED

DIC Patient Care

This includes:
- An attempt to measure blood loss
- Labs
- Wound care, pressure to the site
- Turn and Position
- Frequent mouth care
- Antibiotics AFTER a culture
- Emotional support
* If they survive, NO aspirin

Syndrome of Inappropriate Antidiuretic Hormone (SIADH)

This is an oncological emergency where there is a hyper-secretion of ADH by the posterior pituitary glad.
- It causes fluid retention and hyponatermia (Normally 135 - 145). The level it will usually be is around 110.
- This is most common with brain and l

SIADH Signs and Symptoms

These include:
- Edema, weight gain, crackles, jugular vein distention
- Anorexia, fatigue, muscle cramp, Decreased urine, changes in mental status, seizures

SIADH Nursing Interventions

These include:
- Diuretics, usually lasix
- Restrict fluid intake 800ml-1L a day
- Monitor: Electrolytes, I&O, daily weight, neuro status
- Never let them get up alone

Spinal Cord Compression

This is an oncological emergency where a tumor invades the spinal cord, vertebral column collapses. With this, there is extreme pain, worse with movement.

Spinal Cord Compression Signs and Symptoms: Early

This includes Back pain or neck pain

Spinal Cord Compression Signs and Symptoms: Late

These include:
- Loss of sensation
- Incontinence
- Sexual Impotence
- Paralysis
- Muscle Atrophy

Spinal Cord Compression Treatment

With this, use deep breathing and incentive spirometer to prevent respiratory problems.
Also, log rolling
Pharmacologically:
- High dose corticosteriods to reduce edema and pain
- Chemotherapy as adjunt to radiation and surgery
- Analgesics

Hypercalcemia

This is an oncological emergency that is a late manifestation of malignancy with bone metastasis. This develops very slowly

Hypercalcemia Signs and Symptoms

These include:
- Fatigue, constipation, decreased deep tendon reflexs
- EKG changes: Tachycardia then Bradycardia which leads to cardiac arrest

Hypercalcemia Treatment

This is done only when symptoms occur. You give oral or IV hydration, Calcitonin, and Dialysis possibly if its very high.

Superior Vena Cava Syndrome

This is an oncological emergency where the SVC is compressed or obstructed by a tumor growth. There is a blockage of blood flow in the neck, head, and upper arms. It is painful and life threatening. Symptoms usually occur in the morning.

Superior Vena Cava Syndrome Signs and Symptoms: Early

These include:
- Edema of the face, neck, eyes, arms, and hands
- Stokes sign - tightness of the shirt and blouse
- Dyspnea
- Neck and vein distention

Superior Vena Cava Syndrome Signs and Symptoms: Late

These include:
- Severe headache
- Stridor
- Hemorrhage
- Cyanosis
- Hypotension
- Change in mental status

Superior Vena Cava Syndrome Treatment

With this, high dose radiation to the mediastinal area is used as a treatment.

Tumor Lysis Syndrome

This is an oncological emergency where cancer cells become destroyed, but in the process, large amounts of potassium and uric acid are released from those destroyed cells. This can cause acute renal failure, and cardiac dysrhythmias.

Tumor Lysis Syndrome Treatment

With this, monitor urine pH to prevent ARF. You want a pH below 6.57.
- Also, hydration is important. Have patients drink the day before, of, and 3 days after treatment at scheduled times.
- do an EKG
- Medication - Alopurinol to decrease uric acid.
