The History of Phlebotomy

Ancient Phlebotomy

Phlebotomy, the practice of drawing blood, has a long and fascinating history. While the techniques and purposes have evolved significantly over time, the core concept of obtaining blood samples for diagnostic or therapeutic purposes remains constant.

Ancient Origins:

Evidence of bloodletting (the ancient term for phlebotomy) practices dates back to ancient civilizations like Egypt and Greece.
These early practices were often based on theories of humoral balance, where blood was believed to be one of four essential fluids that needed to be in balance for good health.

Evolving Practices:

Over the centuries, phlebotomy has undergone significant transformations.

Early methods were often crude and sometimes harmful, with excessive bloodletting being a common practice.

Modern phlebotomy utilizes advanced techniques, sterile equipment, and a strong emphasis on patient safety and comfort.

Modern Applications:

Today, phlebotomy plays a crucial role in modern medicine, enabling a wide range of diagnostic tests and therapeutic procedures.

Blood samples are essential for diagnosing diseases, monitoring treatment, and ensuring patient well-being.

Phlebotomy Ethics

Phlebotomy plays a critical role in healthcare, and adhering to a strong ethical framework is paramount.

Two organizations set certain standards for phlebotomists in BC:

The Canadian Society for Medical Laboratory Science (CSMLS) is the national certifying body and professional association for medical laboratory professionals across Canada.
- - CSMLS plays a crucial role in setting and maintaining the highest standards of practice for medical laboratory professionals across the country.
  - CSMLS advocates for the interest of medical laboratory professionals as well as supporting the professional development of its members through continuing education programs, conferences, and publications.
  - They offer a national certification program that recognizes the competence and knowledge of medical laboratory professionals.
  - CSMLS certification is highly regarded within the healthcare community and demonstrates a commitment to excellence and professionalism.
The British Columbia Society of Laboratory Sciences (BCSLS) is the provincial regulatory body for medical laboratory professionals in British Columbia, Canada.
- - BCSLS plays a crucial role in setting a maintaining high standards of practice for medical laboratory professionals within the province.
  - BCSLS advocates for the interests of medical laboratory professionals within the province of British Columbia, ensuring their voices are heard on important issues related to healthcare and laboratory practices.
  - BCSLS certification signifies a high level of professional competence and ensures that medical laboratory professionals in British Columbia meet rigorous standards of education, training, and ethical conduct.

Core Principles in Phlebotomy Ethics

Informed Consent:

Obtaining informed consent is fundamental for phlebotomists. This involves clearly explaining the procedure, potential risks, and benefits to the patient.

When a student performs a blood draw, it is crucial to prioritize open and honest communication with the patient.
- Students must clearly identify themselves as a student phlebotomist.
- This transparent approach builds trust and allows the patient to make an informed decision about whether they are comfortable with a student performing the procedure.

Patients must understand the procedure and have the right to refuse or withdraw consent at any time.

Confidentiality:

Maintaining patient confidentiality is a fundamental ethical principle in phlebotomy. Patient information, including medical history, test results, and personal details must be treated with the utmost respect and discretion.

Phlebotomists must only share patient information with authorized individuals who have a legitimate need to know, such as physicians or other healthcare professionals directly involved in the patient's care.
Sharing patient information with friends, family, or colleagues is strictly prohibited.

Protection of Personal Health Information (PHI):

The Personal Information Protection and Electronic Documents Act (PIPEDA) is a federal law in Canada that outlines the rules for how personal information, including medical history, test results, and personal details, are used within an organization. This legislation has significant implications for phlebotomists as they work with sensitive patient data on a daily basis.

By understanding and adhering to the principles of PIPEDA, phlebotomists can ensure that they handle patient information responsibly, maintain patient trust, and uphold the highest standards of ethical conduct in their profession.

Special Population Collections

Phlebotomy procedures require careful consideration and adaptation when dealing with special populations, such as pediatric and geriatric patients.

Pediatric Patients:

Pediatric patients, defined as individuals under the age of 18, require specialized care and consideration during phlebotomy procedures. Children, especially infants and toddlers, have unique physical and developmental needs.

Their veins may be smaller and more difficult to locate.
Bandages are avoided for children under 2 years old, due to the risk of choking.

When collecting blood from newborns, the heel is the preferred site for blood collection due to its lower risk of complications and relative ease of obtaining a sufficient blood sample. While there is no strict cut-off for heel pokes, once an infant begins to crawl or walk, the risk of the infant rubbing the heel against surfaces and reopening the puncture site significantly increases. As infants become more mobile, finger capillary pokes may become a safer and more practical option for blood collection.

Careful attention must be paid when performing an infant heel poke to avoid puncturing the underlying bone.

Age-appropriate communication and distraction techniques are crucial to minimize anxiety.

Creating a calm and reassuring environment is essential.
Distraction techniques, such as singing, playing music, or offering a toy, can help to alleviate anxiety.
Gentle restraint may be necessary to ensure patient safety, such as a firm grip on an infant's foot or a parent holding the child.

Geriatric Patients:

Geriatric patients may have age-related changes in their skin, making vein access more challenging.

Some geriatric patients may have cognitive impairment or physical limitations that require special attention.
Special care must be taken to avoid bruising or injuring fragile skin.
Clear and concise communication, patience and understanding are crucial when dealing with anxious or confused geriatric patients.
Rely on wristbands or other forms of identification to ensure accurate patient identification, as some patients may have difficulty communicating their information.

Phlebotomists must possess the knowledge and skills to adapt their techniques to the specific needs of each patient population. By understanding the unique challenges and considerations associated with pediatric and geriatric patients, phlebotomists can ensure safe, effective and compassionate care for all individuals.

Pediatric and Geriatric Patients

Consequences of Inaccurate Blood Draws

Inaccurate blood draws can have significant consequences for both patients and healthcare providers.

Impact on Patient Care

Inaccurate blood collection techniques can lead to inaccurate test results, such as hemolysis (rupture of red blood cells), contamination, or clotting. This can misdiagnose patient conditions, delay appropriate treatment, and potentially lead to adverse health outcomes.
Inaccurate results may necessitate repeat blood draws, causing additional discomfort, anxiety, and potential complications for the patients.
Delayed or inaccurate diagnoses due to flawed blood samples can significantly impact the timing and effectiveness of patient treatment.
Excessive probing, missed veins, or improper needle insertion can cause pain, bruising, hematomas, and discomfort for the patient.
Repeated unsuccessful blood draws or painful experiences can erode patient trust in the healthcare system.

Healthcare Worker Safety

Accidental needlesticks can expose healthcare workers to bloodborne pathogens such as HIV, Hepatitis B, and Hepatitis C.
Inaccurate blood draws can have legal implications, particularly if they lead to misdiagnosis or adverse patient outcomes.
Maintaining high standards of practice and adhering to safety protocols are essential for ethical and professional conduct.

By adhering to proper phlebotomy techniques and prioritizing patient safety and comfort, healthcare professionals can minimize the risks associated with inaccurate blood draws and ensure the highest quality of patient care.

Fun Fact!

There are 3 veins in the antecubital fossa (the inner elbow): The Median Cubital, the Cephalic Vein, and the Basilic Vein. These veins, from more ideal vein to least, are the most common veins to use during venipuncture.

The first choice being the Median Cubital vein as it is least likely to roll during venipuncture and isn't near any important nerves or tendons.
The second choice being the Cephalic vein as it is accessible however it may easliy roll due to its smaller size, leading do an unsuccessful venipuncture.
The Basilic vein being a last resort is due to it being so closest to tendons, nerves, and arteries. If a nerve gets hit then the patient may feel a sharp shooting pain throughout their arm. Overall, this vein has more risk associated with it rather than the Median Cubital or the Cephalic vein. So, for patient safety this vein is a last choice and only used unless necessary.

There are different types that these veins can be arranged in, the most common patterns being that they show up in an 'H' pattern or an 'N' pattern.

If you look closely at your antecubital fossa (inner elbow) you will be able to figure out which one you are! Try it out and give it a look!
