1.0 INTRODUCTION



Cytology is a discipline that involves the morphologic study of cells. It is broadly
divided into exfoliative cytology and aspiration cytology.

Exfoliative cytology involves examination of specimens that contain cells exfoliated CYTOLOGY
from body cavities and surface. It is further subdivided into gynaecological cytology
(Pap/cervical smears) and non-gynaecological cytology (pleural fluid, peritoneal fluid,
cerebrospinal fluid, urine, sputum, brushing, etc).

Aspiration cytology involves examination of cells that are actively obtained by fine
needle aspiration.

clinical staffs.
• Fill in the checklist after checking the blood.
• Ensure patients received the right blood by checking the blood bag against
request form, PPDK card, patient’s wrist band/patient ID and verbal
confirmation with the patient.
• Check each unit the same way just before it is transfused.
• Vital signs (BP, HR, Temp) must be taken before transfusion of each unit.
• Close monitoring for the first 15 minutes, then every half to one hour (if no
complications).
• Avoid transfusion in the evening or nights unless inan emergency situation.
• Document the details of the transfusion (vital signs, blood units transfused,
reactions).
• Complete the PPDK card only after transfusion is finished.
• Fill in the necessary details and sign the card. This can be done by
doctor or staff nurse.
• Return the card with the used blood bag to blood bank (BB).
• Stop the transfusion immediately if the patient shows any reaction. Resume
transfusion only if the reaction is mild and not due to red cell incompatibility,
TRALI and bacterial contamination and the patient benefit from medications
given e.g. antihistamine or antipyretic agents.
• Investigate all reactions.
• Return all used blood bags to Blood Bank – empty or not, and any unused
blood units.
• Should the patient needatransfusionand the blood has been returned, make
a fresh request.

















229

10.0 PATIENTS DETAILS

a. The process of taking and labeling the blood samplemust be done at the bedside,
HTAA, KUANTAN b. The phlebotomist taking the blood sample must ask the patient to state his/her
one patient at a time.
full name and IC number. This information then must be checked against the
wristband and patient’s case notes.


11.0 REQUESTS FOR EMERGENCY BLOOD

In emergency cases, the request form and blood sample must be sent by a doctor to
the blood bank and wait for the blood to be supplied.
In this request, a stamp/chop of ‘EMERGENCY CROSS-MATCHED’ will be placed in
which the doctor must pass a signature before the blood can be supply by blood bank.

Note:
In emergency cross-matched, saline phase cross-matched blood will be supplied in
which limited safety is guaranteed. Full cross-matching will be carried out by the
laboratory. Any incompatibility will be notified to the requesting doctor.



12.0 USED BLOOD OR REMNANTS OF BLOOD

Blood transfusion discontinued for any reason should not be used again and must
be returned to the Blood Bank as soon as possible, together with all the details of the
transfusion and reason for discontinuing the blood transfusion stated on the recipient
card (PPDK 1) attached to the bag. All discontinued blood must be labeled “USED
BLOOD” before returning to the Blood Bank.




















230

13.0 RETURN OF BLOOD BAGS

a. Used blood bags

On completion of blood transfusion, the ward staff must ensure the Recipient Card
(PPDK 1) is filled and returned to the Blood Bank together with the blood bag containing
remnants of the blood transfused at any time. TRANSFUSION

Note : Please ensure the Recipient Card (PPDK 1) is not tainted with blood.

b. Unused blood and Blood Component

All unused blood issued to the ward must be sent back to blood bank immediately
if the transfusion is delayed or cancelled. (<2 hrs).

All unused blood component (platelets, FFP, cryo precipitate) must be send back to
blood bank immediately WITH an explanation letter.

Note: Please practice judicious use of blood and blood component to avoid wastage.




14.0 RESERVATION OF CROSS-MATCHED BLOOD

Blood which has been cross-matched for any patient will be kept in reserve for 48
hours only. In the absence of specific instruction to the medical officer in charge of
Blood Bank, the blood will be returned (released) to the general pool automatically.























231

15.0 TRANSFUSION REACTION


The use of blood even under the best circumstances carries a high risk for the recipient.
HTAA, KUANTAN The commonest risk is transfusion reaction. Examples of these are :

a. Febrile reaction to pyrogens, leucocyte antibodies, platelet antibodies and
minor blood group antibodies.
b. Allergic reactions to plasma constituent.

For patient with repeated history of febrile reaction during transfusion, filtered
blood can be used to prevent similar reactions.


15.1 HAEMOVIGILANCE

Haemovigilance is a set of surveillance procedures covering the whole transfusion
chain ,from the donation of blood and its components to the follow-up of recipients of
transfusions intended to collect and assess information on unexpected or undesirable
effects resulting from the therapeutic use of labile blood products and to prevent the
occurrence or recurrence of such incidents.

The aim of haemovigilance is to increase awareness of the above mentioned situations
and thus raise the level of transfusion quality and safety by means of corrective and
preventive measures.

The haemovigilance system requires cooperation between all the different parties
involved: Blood Bank, the centre responsible for the donation and the blood donors, as
well as those responsible for the preparation, storage and supply of blood components
and the clinical services at the different hospitals where the transfusion will finally take
place.

This system is coordinated by theHaemovigilance coordinating centre at the National
Blood Centre. The functions of this coordinating centre are:


• To collect reports of all adverse events associated with blood transfusion which
includes transfusion reaction, donor reaction and other deviation from the
norm relating to supplies of reagent, equipment , blood bags, etc.
• Analyse the reports submitted.






232

• Prepare and issue annual report which include recommendation for corrective
action to the ministry of health.
• Upon receipt of the “REPORT OF REACTION TO BLOOD OR PLASMA” forms (PPDK
22-Pin. 1/80) by the Hospital Blood Bank, the reporting format for “Adverse
Transfusion Event (Borang X) will be issued to the ward / doctor concerned by
the Hospital Blood Bank. TRANSFUSION
• The “Adverse Transfusion Event” (Borang X) form will be returned in duplicate
to the Hospital Blood Bank and National Blood Centre within one week.
• A copy of this form (Borang X) will be sent to the National Blood Centre, refer to
the flowchart for reporting of adverse transfusion events below:

Flowchart for reporting of adverse transfusion events

Adverse transfusion events































Note:
• Every case of adverse reaction must be reported .
• If the case of adverse reaction involvesa seropositive donor, a look back and
recall procedure must be carried out.
• Identity card number (I/C), donation date must be summitted to Surveillance
Unit , National Blood Centre.


233

16.0 INVESTIGATION OF TRANSFUSION REACTION

This is conducted when a patient develops a transfusion reaction such as febrile or
HTAA, KUANTAN Important : All reactions must be reported immediately.
suspected haemolytic reaction.



The blood bag (with the remaining blood) and giving set (with all attached labels)
should be preserved for culture. Secure it properly to prevent spillage and send
immediately to Blood Bank together with the following forms which must be completely
and accurately filled :

i. PPDK 22-Pin. 1/80 (Report of Reaction To Blood or Plasma)
ii. Borang X (Reporting Format For Adverse Transfusion Event)
iii. PER-PAT 301
iv. HAEM/JP/HTAA/01Ver.2 (Haematology Request Form)

The following samples and forms must be taken stating patient’s name and identifying
data and labeled as Post-transfusion 1 :

i. 8 ml of blood into EDTA tube (4 ml).
ii. 2.5 ml EDTA blood for Full Blood Picture (FBP) by case basis.
iii. 20 ml of urine.

A second set of samples, 24 hours after the reaction should be taken and labeled as
Post-transfusion 2 including:

i. 10 ml of blood in a plain tube.
ii. 2.5 ml EDTA blood for Full Blood Picture (FBP) by case basis.
iii. 20 ml of urine.
