FDA Box Warning

Epidural or spinal hematomas may occur in patients who are anticoagulated with low-molecular-weight heparins or heparinoids and are receiving neuraxial anesthesia or undergoing spinal puncture. These hematomas may result in long-term or permanent paralysis. Consider these risks when scheduling patients for spinal procedures. Risk increases with use of indwelling epidural catheters, concomitant use of drugs affecting hemostasis (such as nonsteroidal anti-inflammatory drugs, platelet inhibitors, or other anticoagulants), traumatic or repeated epidural or spinal puncture, or history of spinal deformity or spinal surgery.

Monitor patient frequently for signs and symptoms of neurologic impairment. If these occur, provide urgent treatment.

Consider benefits and risks before neuraxial intervention in patients anti-coagulated or to be anticoagulated for thromboprophylaxis.

Nursing implications

Nursing assessment

  • Assess for signs of bleeding and hemorrhage (bleeding gums; nosebleed; unusual bruising; black, tarry stool; hematuria; fall in hematocrit or BP; guaiac-positive stools). Notify health care professional if these occur.
  • Subcutaneous: Observe injection sites for hematoma, ecchymosis, or inflammation.
  • Lab Test Considerations: Monitor CBC, platelet count, and stools for occult blood periodically during therapy. If thrombocytopenia occurs, monitor closely. If hematocrit ↓ unexpectedly, assess patient for potential bleeding sites.
    • Special monitoring of clotting times (aPTT) is not necessary.
    • May cause asymptomatic ↑ in transaminase levels (AST, ALT).

Potential Nursing Diagnoses

Ineffective tissue perfusion (Indications)
Risk for injury (Side Effects)

Implementation

  • First dose is administered 1–2 hr before surgery.
    • Dalteparin cannot be used interchangeably (unit for unit) with unfractionated heparin or other low-molecular-weight heparins.
  • Subcutaneous: Administer deep subcut while patient is sitting or lying down. Dalteparin may be injected into the abdominal wall inferior and lateral to the umbilicus, the upper outer side of the thigh, or the upper outer quadrant of the buttock. Rotate injection sites daily. Inject entire length of needle at a 45° or 90° angle while lifting and holding skin between thumb and forefinger.
    • Do not administer IM.
  • Syringe Incompatibility: Do not mix with other injections or infusions.

Patient/Family Teaching

  • Advise patient to report any symptoms of unusual bleeding or bruising, dizziness, itching, rash, fever, swelling, or difficulty breathing to health care professional immediately.
  • Instruct patient not to take aspirin or NSAIDs without consulting health care professional while on dalteparin therapy.

Evaluation/Desired Outcomes

  • Prevention of deep vein thrombosis and pulmonary embolism.
  • Prevention of ischemic complications (with aspirin) in patients with unstable angina or non-Q-wave MI.
