Phlebotomy, also referred to as venipuncture, is the surgical puncture of a vein in order to draw blood from a patient. It is one of the most routinely performed invasive procedures and is carried out for two reasons, to obtain blood for diagnostic purposes or to monitor levels of blood components
It’s carried out by a qualified professional called a “Phlebotomist’. The blood sample obtained is then studied by a physician to determine the health and condition of a patient.
Nurses and many other medical professionals generally have obtained training in Phlebotomy, however students who intend to go on to become professional doctors may start in a hospital or a medical facility working as a Phlebotomist.
The procedure begins by the Phlebotomist first verifying the patient’s identity and preparing the necessary equipment. At this point the Phlebotomist washes his or her hands and places on gloves. The patient’s arm is then placed on a flat surface so that it is extended and well supported. After selecting a distal and accessible vein, the Phlebotomist applies a tourniquet just four inches above the selected infusion site and the patient is usually instructed to clench his or her hand.
The selected site is thoroughly cleaned using an alcohol swab and allowed to dry before inserting the needle. Once the blood has begun flowing into the sample bottle, the tourniquet is removed and the patient is instructed to relax his or her hand. Once the required samples are collected, the needle is withdrawn and gauze is firmly placed and held over the infusion site. The tube(s) are then labelled and any contaminated materials are disposed of in the designated areas.
The sample of blood taken from the patient has to be prepared for laboratory analysis, so it’s important it’s handled properly using the right procedures to prevent it from becoming contaminated in any way.
One of the most important aspects of working as a Phlebotomist is to be able to reassure nervous patients and to become proficient at drawing blood without causing distress or pain.
Taking blood from patients is an extremely important part of any medical procedure as it helps to establish the patient’s medical condition. Diagnosis of their problem is the first step in making sure they receive the correct treatment in order to facilitate a cure.
The advancement of medical science has excelled in the last century. The ability to diagnose and treat a patient by examining a small sample of their blood has in many instances made it possible to prevent a serious illness from progressing.
Phlebotomy plays an extremely important role in discovering discrepancies in a patient’s blood that may be causing health problems. It’s a Phlebotomist’s care and consideration during the procedure that will make a patient feel secure.
