24-Hour Blood & Transfusion Support for Emergency, Surgical and Inpatient Care

The Blood Bank at AS Medical Complex is designed to provide 24-hour blood and transfusion support for patients who require blood or blood components as part of emergency treatment, surgery, childbirth, medical care, or other clinically indicated treatment.

Blood transfusion can be a life-saving medical intervention.

Patients may require transfusion because of:

• Severe blood loss

• Major trauma

• Surgery

• Childbirth-related bleeding

• Severe anemia

• Blood disorders

• Cancer treatment

• Selected kidney or chronic medical conditions

• Other clinical situations

However, blood transfusion must be used carefully.

WHO emphasizes that safe blood transfusion requires appropriate donor selection, screening of donated blood, correct storage, compatibility testing, appropriate clinical use, and monitoring throughout the transfusion process.

The Blood Bank works closely with:

• Emergency Department

• General & Laparoscopic Surgery

• Gynecology & Obstetrics

• Labour Room

• Orthopedics

• Neurosurgery

• General Medicine

• Hematology

• Nephrology

• Pediatrics

• Anesthesia

• Operating Theatre

• Laboratory

• Other hospital departments

depending on the patient's condition.

The exact blood components routinely stocked, donor-collection arrangements, and specialist transfusion services should be confirmed before individual products are promoted as continuously available.

The Role of a Hospital Blood Bank

A hospital Blood Bank is not simply a storage area for blood.

It is part of a structured transfusion-safety system.

Its responsibilities can include:

• Determining blood groups

• Receiving or collecting blood

• Screening or verifying blood suitability according to applicable systems

• Processing or obtaining blood components

• Maintaining appropriate storage conditions

• Checking compatibility between donor blood and the patient

• Issuing blood for clinical use

• Maintaining identification and traceability

• Supporting investigation of transfusion reactions

WHO describes these interconnected processes as part of haemovigilance and blood-transfusion safety, covering the pathway from blood collection through transfusion and monitoring of the recipient.

Blood & Blood Components

Modern transfusion medicine often allows different components of donated blood to be used according to the patient's specific need rather than automatically giving whole blood.

Depending on the Blood Bank and clinical indication, components can include:

Red Blood Cells

Red cells carry oxygen throughout the body.

Red Blood Cell transfusion may be considered in selected patients with:

• Significant blood loss

• Severe or symptomatic anemia

• Surgical bleeding

• Other conditions in which increasing oxygen-carrying capacity is clinically necessary

Platelets

Platelets help the blood form clots.

Platelet transfusion may be required in selected patients with:

• Very low platelet counts

• Active bleeding associated with thrombocytopenia

• Platelet dysfunction

• Certain cancer treatments

• Selected procedures

Plasma

Plasma is the liquid portion of blood and contains proteins including clotting factors.

Plasma transfusion may be required in selected patients with:

• Significant clotting abnormalities

• Major bleeding

• Selected liver-related coagulation problems

• Other clinically appropriate conditions

The correct component should be selected according to the patient's actual medical requirement.

WHO recommends rational clinical use of blood to reduce unnecessary transfusions and minimize transfusion-related risks.

Who May Need a Blood Transfusion?

Blood transfusion is not based on one laboratory result alone.

Doctors consider the complete clinical picture.

Transfusion may be required in selected patients experiencing:

• Acute blood loss

• Major trauma

• Severe surgical bleeding

• Postpartum haemorrhage

• Gastrointestinal bleeding

• Severe symptomatic anemia

• Selected blood disorders

• Bone-marrow disease

• Cancer treatment-related blood-cell reduction

• Significant clotting abnormalities

• Other medical or surgical conditions

The decision may consider:

• Hemoglobin level

• Amount and rate of bleeding

• Symptoms

• Blood pressure

• Heart rate

• Oxygenation

• Heart disease

• Patient age

• Other illnesses

WHO recommends avoiding unnecessary transfusion and using blood only when the expected clinical benefit outweighs the associated risks.

Severe Blood Loss & Emergency Transfusion

Severe blood loss can become life-threatening because the body may no longer be able to maintain adequate:

• Circulating blood volume

• Blood pressure

• Oxygen delivery

• Organ perfusion

Major blood loss can occur because of:

• Road traffic accidents

• Major trauma

• Surgery

• Gastrointestinal bleeding

• Obstetric haemorrhage

• Internal bleeding

• Other emergencies

Emergency treatment may involve:

• Rapid clinical assessment

• IV access

• Laboratory testing

• Blood grouping

• Compatibility testing

• Blood-component transfusion

• Treatment of the source of bleeding

• Surgery or another procedure where necessary

In immediately life-threatening circumstances, emergency transfusion pathways may differ from routine transfusion procedures according to established hospital protocols.

Blood Support During Surgery

Blood Bank services are an important part of surgical care.

Before selected operations, doctors may request:

• Complete Blood Count

• Blood group

• Antibody screening where appropriate

• Crossmatching

• Reservation or availability of blood components

depending on:

• Type of surgery

• Expected blood loss

• Patient's hemoglobin

• Previous transfusions

• Previous pregnancies

• Medical history

• Other risk factors

Not every operation requires blood to be crossmatched or transfused.

Blood should be prepared according to the expected clinical need.

Blood Support in Obstetrics & Labour Room

Blood availability can be particularly important in maternity care because significant bleeding can sometimes develop rapidly during or after childbirth.

Blood Bank support may be needed in selected cases involving:

• Postpartum haemorrhage

• Placental complications

• Caesarean Section

• Severe antenatal anemia

• Obstetric surgery

• Other maternal emergencies

Rapid communication between:

• Labour Room

• Obstetrics & Gynecology

• Anesthesia

• Operating Theatre

• Laboratory

• Blood Bank

can be important when major obstetric bleeding occurs.

Severe Anemia

Anemia occurs when the blood does not have an adequate amount of functioning red cells or hemoglobin.

Possible symptoms can include:

• Fatigue

• Weakness

• Shortness of breath

• Palpitations

• Dizziness

• Reduced exercise tolerance

Not every patient with anemia requires a transfusion.

Many forms of anemia are better treated by identifying and correcting the cause.

Treatment may include:

• Iron

• Vitamin replacement

• Treatment of bleeding

• Treatment of kidney disease

• Management of an underlying blood disorder

• Other therapies

Red Blood Cell transfusion is usually reserved for situations where the clinical condition warrants it.

Patients Requiring Repeated Transfusions

Some patients require transfusion repeatedly because of chronic blood disorders or other medical conditions.

For example, CDC notes that blood transfusions are an important treatment for moderate and severe forms of thalassemia.

Patients receiving repeated transfusions may require additional monitoring because complications can include:

• Iron overload

• Development of red-cell antibodies

• Transfusion reactions

• Other treatment-related problems

CDC specifically identifies iron overload and alloimmunization among complications that can occur in people receiving regular transfusions.

Such patients may require coordinated care involving Hematology and other relevant specialists.

Blood Donation & Donor Assessment

Where blood donation is collected through the AS Medical Complex Blood Bank, each prospective donor should undergo appropriate eligibility assessment.

The purpose of donor screening is to protect:

• The donor

• The patient receiving the blood

Assessment may include:

• Medical history

• Current health

• Previous illnesses

• Medication

• Previous donation history

• Relevant infection-risk assessment

• Hemoglobin or other pre-donation checks

• Other criteria required by applicable blood-safety standards

WHO emphasizes that donors should be in good health when donating and that eligibility criteria can vary according to national blood-service requirements.

A person who wants to donate should therefore be assessed rather than assuming they are automatically eligible.

Who May Be Temporarily Unable to Donate Blood?

Eligibility rules vary according to the applicable blood-service policy, but donation may need to be postponed in selected circumstances such as:

• Current infection

• Fever

• Significant illness

• Certain recent procedures

• Some medications

• Pregnancy

• Low hemoglobin

• Other temporary medical conditions

WHO states that individuals who are currently unwell with illnesses such as flu, sore throat, stomach infection, or another active infection should not donate until appropriate recovery.

Final donor eligibility should always be determined by the responsible blood-service professional.

Voluntary Blood Donation

WHO supports systems based on voluntary, unpaid blood donation because regular low-risk voluntary donors are an important foundation of a safe and sustainable blood supply.

Regular blood donation can help hospitals maintain supplies for patients requiring:

• Emergency transfusion

• Surgery

• Obstetric care

• Cancer treatment

• Blood-disorder treatment

• Other medical care

Blood availability can become particularly important when:

• A rare blood group is required

• Multiple components are needed

• Major bleeding occurs

• Demand increases unexpectedly

Testing Donated Blood

Safe transfusion requires appropriate screening of donated blood before it is released for patient use.

WHO states that all donated blood should be screened for major transfusion-transmissible infections including:

• HIV

• Hepatitis B

• Hepatitis C

• Syphilis

using quality-assured testing systems.

Additional testing and requirements may be determined by applicable national regulations and blood-service protocols.

Blood should not be considered suitable for transfusion merely because a donor appears healthy.

Blood Groups

The major ABO blood groups are:

• A

• B

• AB

• O

Blood is also commonly classified according to the Rh system, particularly whether the patient is:

• Rh positive

• Rh negative

Accurate blood-group identification is essential because transfusing incompatible red cells can cause a serious transfusion reaction.

Blood-group testing therefore forms an important part of pre-transfusion assessment.

Compatibility Testing & Crossmatching

Knowing that a patient and blood unit have the same ABO and Rh type is important, but transfusion safety can require additional compatibility assessment.

Crossmatching helps determine whether donor red cells are compatible with the intended recipient.

Pre-transfusion processes may involve:

• ABO typing

• Rh typing

• Antibody screening where applicable

• Selection of appropriate blood units

• Crossmatching

• Final identification checks

WHO blood-transfusion guidance emphasizes correct identification and compatibility procedures because errors in matching blood to the correct patient can cause severe harm.

Why Previous Transfusions Matter

Patients should tell the healthcare team if they have previously received blood.

Previous transfusion can sometimes result in development of antibodies against red-cell antigens.

This can make finding compatible blood more complicated.

Patients should also report any previous transfusion reaction.

CDC advises patients who have received previous transfusions to share both their transfusion history and any previous reactions with healthcare professionals.

Pregnancy History & Blood Compatibility

Pregnancy can also expose a woman to red-cell antigens and contribute to development of antibodies.

For this reason, previous pregnancy history may sometimes be relevant during pre-transfusion testing.

If clinically significant antibodies are identified, additional testing may be required to locate compatible blood.

The Blood Bank and treating clinician determine the appropriate compatibility process.

What Happens Before a Blood Transfusion?

Before transfusion, the clinical team typically confirms:

• Why transfusion is needed

• Patient identity

• Blood group

• Compatibility

• Correct blood component

• Relevant medical history

• Previous transfusion reactions

• Other appropriate safety information

A pre-transfusion blood sample may be collected for:

• Blood grouping

• Antibody testing

• Crossmatching

according to the clinical requirement.

Careful patient identification is critical throughout this process.

What Happens During a Blood Transfusion?

During transfusion:

• The patient's identity is checked.

• The blood component is verified.

• The transfusion is started according to the clinical protocol.

• The patient is observed for possible adverse reactions.

• Vital signs may be monitored.

• The transfusion is documented.

The exact monitoring process depends on:

• Type of component

• Patient's condition

• Previous reaction history

• Hospital protocol

If concerning symptoms develop during transfusion, the clinical team should evaluate the patient immediately.

Blood Transfusion Reactions

Blood transfusion is generally safe when appropriate systems are followed, but reactions can still occur.

CDC states that allergic and febrile reactions are among the most commonly reported transfusion reactions, while serious complications are much less common.

Possible transfusion reactions can include:

• Fever

• Chills

• Rash

• Itching

• Breathing difficulty

• Chest or back discomfort

• Blood-pressure changes

• Hemolytic reactions

• Circulatory overload

• Other complications

A patient developing new symptoms during a transfusion should immediately alert the nurse or doctor.

Signs to Report During Transfusion

Tell healthcare staff immediately if you develop symptoms such as:

• Fever

• Chills

• Shivering

• Rash

• Itching

• Facial swelling

• Breathing difficulty

• Chest pain

• Back pain

• Severe anxiety or discomfort

• Nausea

• Dizziness

• Other sudden symptoms

Do not wait for the transfusion to finish before reporting a possible reaction.

Fever During a Blood Transfusion

Fever can occur because of several causes.

It may represent:

• Febrile transfusion reaction

• Existing patient infection

• Hemolytic reaction

• Bacterial contamination

• Another medical problem

CDC advises clinicians to consider bacterial contamination when evaluating fever associated with blood-product transfusion, particularly with platelet products.

A fever developing during transfusion therefore requires clinical assessment rather than being automatically dismissed.

Allergic Transfusion Reactions

Some patients develop allergic symptoms during transfusion.

These may include:

• Itching

• Hives

• Rash

Severe allergic reactions are less common but can include:

• Breathing difficulty

• Wheezing

• Facial swelling

• Circulatory instability

The appropriate treatment depends on the severity.

Patients with a previous severe transfusion reaction should inform their healthcare team before future transfusions.

Hemolytic Transfusion Reactions

A hemolytic reaction occurs when transfused red cells are destroyed by the recipient's immune system.

Severe acute hemolytic transfusion reactions can be dangerous.

Possible symptoms may include:

• Fever

• Chills

• Pain

• Low blood pressure

• Dark urine

• Other signs of acute illness

Correct patient identification and compatibility testing are important safeguards against preventable incompatible transfusion.

Infection Risk From Blood Transfusion

Blood transfusion can potentially transmit infections.

However, donor selection, blood screening, testing, and appropriate handling substantially reduce this risk.

CDC notes that transfusion-transmitted infections are now uncommon in systems with modern blood-safety procedures, although the risk cannot be considered absolutely zero.

WHO emphasizes screening, quality systems, safe collection and appropriate clinical use as essential parts of blood safety.

Blood Storage & The Blood Cold Chain

Blood and blood components must be stored under appropriate controlled conditions.

Different components require different:

• Temperature ranges

• Storage equipment

• Handling procedures

• Shelf-life requirements

WHO describes the blood cold chain as essential for maintaining the safety and quality of blood from collection through storage, transportation and transfusion.

Blood Bank systems should therefore include:

• Temperature-controlled storage

• Appropriate refrigerators or other storage equipment

• Temperature monitoring

• Inventory management

• Expiry monitoring

• Traceability

• Safe transport procedures

according to the component being stored.

Blood Traceability

Every blood unit should be identifiable throughout its journey.

Traceability supports the ability to determine:

• Where the blood came from

• How it was tested

• How it was stored

• Which patient received it

• Whether any reaction occurred

This forms part of wider haemovigilance.

WHO describes haemovigilance as surveillance covering the complete transfusion chain to improve transfusion quality and safety.

Preventing Blood Transfusion Errors

Many transfusion errors are preventable.

Safety measures can include:

• Correct patient identification

• Correct labeling of blood samples

• Appropriate blood grouping

• Compatibility testing

• Correct blood-component selection

• Final bedside verification

• Proper documentation

• Appropriate staff training

CDC haemovigilance data and research emphasize that transfusion-related errors can result in adverse reactions and blood-product wastage, reinforcing the importance of systematic prevention.

Blood Bank & Emergency Department

The Blood Bank supports the Emergency Department when patients experience:

• Major trauma

• Severe bleeding

• Gastrointestinal hemorrhage

• Obstetric hemorrhage

• Other acute blood-loss emergencies

Emergency patients may require rapid coordination between:

• Emergency physicians

• Laboratory

• Blood Bank

• Surgery

• Anesthesia

• Operating Theatre

• Other specialists

depending on the condition.

The underlying source of bleeding must also be identified and treated.

Blood transfusion can replace lost blood but does not itself stop the cause of bleeding.

Blood Bank & Surgery

Surgical patients may require Blood Bank support:

• Before surgery

• During surgery

• After surgery

depending on blood loss and the patient's clinical condition.

Blood conservation is also important.

Safe surgical care aims to:

• Prevent unnecessary blood loss

• Correct anemia where possible

• Use blood components appropriately

• Avoid unnecessary transfusion

This approach is consistent with WHO recommendations for rational clinical use of blood.

Blood Bank & Gynecology / Labour Room

Gynecological and Obstetric patients may require transfusion for:

• Postpartum haemorrhage

• Severe antenatal anemia

• Heavy gynecological bleeding

• Ectopic pregnancy with significant bleeding

• Major surgery

• Other conditions

Rapid blood availability can become particularly important in severe obstetric hemorrhage.

Blood Bank & Hematology

Hematology patients may require transfusion support for selected:

• Anemias

• Thalassemia

• Bone-marrow disorders

• Platelet disorders

• Other blood diseases

Repeated transfusions require careful long-term management because patients can develop:

• Iron overload

• Antibodies

• Other complications

The Hematology team determines the appropriate transfusion plan.

Blood Bank & Oncology

Cancer and cancer treatment can sometimes reduce:

• Red Blood Cells

• Platelets

• Other blood cells

Selected Oncology patients may therefore require:

• Red-cell transfusion

• Platelet transfusion

• Other blood-component support

The need depends on:

• Blood counts

• Symptoms

• Bleeding

• Treatment plan

• Clinical condition

Blood Bank & Nephrology

Some patients with advanced kidney disease develop significant anemia.

However, kidney-related anemia is often managed using:

• Iron treatment

• Erythropoiesis-stimulating treatment in selected patients

• Management of underlying kidney disease

rather than routine transfusion.

Blood transfusion may still be required in selected circumstances according to the patient's clinical status.

Blood Bank & Pediatrics

Children may require blood transfusion for conditions such as:

• Severe anemia

• Blood disorders

• Significant bleeding

• Surgery

• Other medical conditions

Pediatric transfusion requires careful attention to:

• Weight

• Blood volume

• Component dose

• Rate of transfusion

• Clinical monitoring

The Pediatrics team should coordinate transfusion decisions according to the child's condition.

Before Receiving a Blood Transfusion

Tell your healthcare team if you:

• Have received blood before

• Have had a previous transfusion reaction

• Know your blood group

• Have known red-cell antibodies

• Are or may be pregnant

• Have had previous pregnancies

• Have significant heart disease

• Have kidney disease

• Are receiving regular transfusions

• Have another important medical condition

Do not rely solely on knowing your own blood group.

The Blood Bank should perform the required testing according to its transfusion protocol.

Can Family Members Donate Blood for a Patient?

Family or friends may sometimes wish to donate blood for a particular patient.

However, directed family donation should not automatically be assumed to be safer than blood obtained through an established donor system.

FDA notes that there is no evidence that directed donation is inherently safer than the general appropriately screened blood supply.

Whether family or replacement donation is accepted should depend on the applicable local Blood Bank policy and donor-eligibility requirements.

When Is Urgent Blood Bank Support Required?

Urgent transfusion support may be required when a patient has:

• Major trauma with blood loss

• Severe gastrointestinal bleeding

• Severe surgical bleeding

• Postpartum haemorrhage

• Ruptured ectopic pregnancy

• Severe symptomatic anemia with clinical instability

• Other major acute blood loss

These patients require Emergency medical treatment, not simply a visit to the Blood Bank.

The Emergency or treating clinical team determines:

• Whether blood is required

• Which component is required

• How urgently it is required

• What additional treatment is necessary

Multidisciplinary Transfusion Care

Safe transfusion requires coordination between multiple clinical services.

Depending on the patient, this may involve:

• Blood Bank

• Laboratory

• Emergency Department

• General Medicine

• Hematology

• General & Laparoscopic Surgery

• Gynecology & Obstetrics

• Labour Room

• Anesthesia

• Orthopedics

• Neurosurgery

• Pediatrics

• Nephrology

• Oncology

• Operating Theatre

• Other relevant specialties

The Blood Bank supplies transfusion support, while the treating clinical team determines the patient's diagnosis and overall management.

Follow-Up After Blood Transfusion

After transfusion, the clinical team may reassess:

• Symptoms

• Vital signs

• Bleeding

• Hemoglobin

• Platelet count

• Coagulation results

• Other Laboratory findings

depending on the reason for transfusion.

Some patients require only one episode of transfusion.

Others with chronic conditions may require:

• Repeated transfusions

• Hematology follow-up

• Iron-overload monitoring

• Antibody evaluation

• Additional treatment

The goal should always be to treat the underlying condition as well as addressing the immediate blood-component requirement.
