The transfusion requirements of a patient are determined by clinical status and laboratory results. Transfusion decisions should take into account the clinical transfusion guidelines, modified to patient needs, and ensuring that the benefits outweigh the risks.

Informed consent must be obtained from the patient for all transfusions of blood or blood products.

In line with the Standards for Practice of Blood Transfusion in SA, no blood products may be issued without the signature of the Medical Practitioner on the Cross match Request Form or a person acting on his/her instructions. All patients’ details on the request form and specimen label must agree.

Indication

  • Prevention of transfusion transmitted CMV.
  • Potential haemopoietic transplant recipients.
  • Intrauterine transfusions and children <1 year of age.
  • Prevention of febrile non-haemolytic transfusion reactions.

Leucocyte deleted (leucodepleted) products

Filtered under laboratory conditions. This ensures optimal removal of leucocytes to minimise cytokine release. Leukocyte depletion will result in a leukocyte count of <5 x 106 per unit and usually <1 x 106 per unit.

Accessories

  • Blood administration set: For the infusion of whole blood and red cell concentrate.
  • Platelet administration set: For the infusion of platelets.
  • Blood pack without anticoagulant: For therapeutic bleeding.
  • Blood pack with anticoagulant: For blood salvage and subsequent autologous re-infusion.

Types of crossmatch

Type and Screen

The specimen will be grouped and tested to ensure that it does not contain antibodies which could delay finding compatible blood. The specimen will be held for 96 hours. Blood will only be cross-matched when requested by the attending doctor.

  • Standard Cross-match is done within 2 hours
  • Emergency cross-match requires 20 – 30 minutes
  • No cross-match requires 5 – 10 minutes

Blood issued on emergency or without compatibility test is transfused at the attending doctor’s own responsibility. There are risks involved in emergency procedures – use them only for genuine emergencies.

Cross-matched products will be held in reserve for 24 hours unless otherwise indicated by the attending doctor.

Blood returnable basis (BRB)

Blood is transported in a temperature controlled hamper. Provided the blood is returned within 10 hours of issue, remains sealed in the hamper and the temperature of the hamper does not exceed 100 C, the fee for the blood will fall away. However, the service and laboratory test charge will be levied.

Informed consent

As with any treatment, the patient has the right to decide whether or not to accept the treatment. As far as possible the patient should understand the benefits, risks and alternatives to transfusion as explained by the prescribing doctor. Informed consent is a process which must be acknowledged and documented.
