Injection, factor viii, (antihemophilic factor, recombinant), (nuwiq), 1 i.u.
HCPCS code
Name of the Procedure:
Injection, Factor VIII, (Antihemophilic Factor, Recombinant), (Nuwiq), 1 I.U.
Common Name: Factor VIII Injection
Technical/Medical Term: Antihemophilic Factor Injection (Recombinant), Nuwiq
Summary
In layman's terms, the injection of Factor VIII (using the product Nuwiq) is a medical procedure used to treat or prevent bleeding episodes in individuals with hemophilia A—a genetic disorder that impairs the body's ability to make blood clots.
Purpose
Factor VIII injections are used to manage bleeding episodes and perform prophylactic treatment for patients with hemophilia A. The goal is to replace the missing or dysfunctional Factor VIII protein in these patients to help their blood clot properly, thereby preventing excessive bleeding and promoting better quality of life.
Indications
The injection is indicated for:
- Treatment of bleeding episodes in patients with hemophilia A.
- Perioperative management when surgery is needed.
- Routine prophylaxis to reduce the frequency of bleeding episodes in patients with hemophilia A.
Specific patient criteria include:
- Confirmed diagnosis of hemophilia A with deficient or defective Factor VIII.
- Patients who require additional clotting support for invasive procedures, injuries, or frequent spontaneous bleeding events.
Preparation
No special fasting or dietary adjustments are usually required. Patients should inform their healthcare provider of any medications they are taking, especially anticoagulants or antiplatelet drugs. Vital signs and baseline laboratory tests, including coagulation profiles, may be assessed before the injection.
Procedure Description
- A healthcare provider prepares the injection by reconstituting the lyophilized powder of recombinant Factor VIII (Nuwiq) with the provided diluent.
- The patient may be seated or lying down in a comfortable position.
- The injection site, generally a vein in the arm, is cleaned with an antiseptic.
- The healthcare provider administers the reconstituted Factor VIII solution into the vein via an intravenous injection.
- The injection process is monitored for any immediate adverse reactions.
Tools/Equipment: Syringe, reconstituted Factor VIII solution, antiseptics. Anesthesia/Sedation: Not typically required.
Duration
The injection itself usually takes a few minutes to administer. The entire appointment, including preparation and monitoring, may last around 30 minutes.
Setting
The injection is often performed in a hospital, outpatient clinic, or specialized infusion center.
Personnel
- Registered Nurse (RN) or Physician (MD/DO) to administer the injection.
- Hematologist or specialist overseeing treatment plan. #### Risks and Complications Common Risks:
- Mild to moderate pain or discomfort at the injection site.
- Allergic reactions (rare).
Rare Risks:
- Development of inhibitors (antibodies) against Factor VIII.
- Bloodborne infections (minimal risk with recombinant products). Possible complications are managed with additional medical interventions or medications.
Benefits
The expected benefits are:
- Preventing or stopping bleeding episodes.
- Reducing the frequency of spontaneous bleeds.
- Enhancing overall quality of life. Patients often notice these benefits immediately after treatment in case of acute bleeds or after a few prophylactic doses for preventive measures.
Recovery
Post-procedure care:
- Patients are usually observed for a short period for any immediate reactions.
- Mild activities can generally be resumed quickly, but heavy physical exertion should be avoided as advised.
- Follow-up appointments may be scheduled to monitor effectiveness and adjust dosages.
Expectations:
- Recovery time is typically minimal—patients can return to normal activities within hours unless advised otherwise by their healthcare provider.
Alternatives
- Other recombinant Factor VIII products.
- Plasma-derived Factor VIII concentrates.
- Non-factor replacement therapies like emicizumab.
Pros and Cons:
- Recombinant products reduce the risk of infections compared to plasma-derived options.
- Alternatives like emicizumab may offer longer intervals between doses but may not be suitable for all patients.
Patient Experience
During the Procedure:
- Patients might feel a slight pinch or sting at the injection site.
- Moments of anxiety can be mitigated through reassurance and comfort measures.
After the Procedure:
- Some patients might experience minor soreness at the injection site.
- Pain management includes over-the-counter pain relievers if necessary and guidance from medical staff for any discomfort.
