Takeaways
- 📚 **Hemodialysis Definition**: Hemodialysis is a process that replicates kidney function by removing waste, balancing electrolytes, and maintaining fluid levels in the blood when the kidneys can't do so effectively.
- 💉 **Vascular Access**: Patients require vascular access, such as a fistula or graft, to facilitate the flow of blood to and from the dialyzer. This access point is critical and needs to be well-maintained.
- ⏱️ **Treatment Frequency and Duration**: Hemodialysis sessions are typically three times a week, lasting about three to five hours each, due to the kidneys' continuous function that cannot be matched by intermittent dialysis.
- 🧼 **Dialysis Process**: Blood is taken from the patient, passed through a dialyzer to remove waste and balance fluids, and then returned to the patient's body.
- 🕰️ **Healing Time for Access**: It takes about six months for a fistula or graft to heal before it can be used for dialysis, which is a crucial waiting period.
- 🚫 **Medication Precautions**: Certain medications that affect blood pressure, fluid levels, or are rapidly cleared by dialysis should be held prior to treatment unless instructed otherwise by a doctor.
- 🤝 **Physical Assessment**: Nurses should regularly assess the vascular access site for signs of proper function, such as a thrill and bruit, and monitor for complications like infection or stenosis.
- 📉 **Monitoring Vital Signs**: During dialysis, it's critical to monitor vital signs, especially blood pressure and temperature, to ensure patient stability.
- 🧫 **Lab Work**: Labs are taken before dialysis to assess the patient's starting levels of BUN, creatinine, electrolytes, and anticoagulant levels to guide treatment.
- ⚠️ **Complications**: Be aware of potential complications like loss of vascular access, infections, bleeding, hypotension, muscle cramps, nausea, vomiting, and disequilibrium syndrome.
- 🧘♀️ **Patient Education**: Educating patients on the importance of vascular access care, recognizing warning signs of complications, and understanding the dialysis process is vital for successful treatment outcomes.
Q & A
What is the primary purpose of hemodialysis?
-The primary purpose of hemodialysis is to clean the blood of patients whose kidneys are not functioning properly. It removes waste, balances electrolytes, and restores the body's fluid balance.
How often do patients typically undergo hemodialysis sessions?
-Patients typically undergo hemodialysis sessions at least three times per week, with each session lasting around three to five hours.
What is vascular access in the context of hemodialysis?
-Vascular access refers to the point of entry for blood to be cleaned during hemodialysis. It can be a fistula, a graft, or a temporary central venous catheter.
What is a fistula and how is it created?
-A fistula is a surgical connection between an artery and a vein. It is created to increase blood flow to the access point, allowing for efficient blood cleaning during dialysis.
Why is it important to assess the fistula or graft before a dialysis session?
-Assessing the fistula or graft is crucial to ensure it is functioning properly and to detect any issues early, such as infection or clotting, which could affect the dialysis process.
What are some warning signs patients should be aware of regarding their vascular access?
-Patients should be aware of paleness, tingling, changes in pulse, cap refill time, and pain in the hand as potential warning signs of vascular access issues.
What is the significance of the 'thill' and 'bruit' in assessing a fistula?
-The 'thill' refers to the palpable vibration felt when touching a functioning fistula, indicating turbulent blood flow. The 'bruit' is the swooshing sound heard through a stethoscope, indicating blood flow through the fistula.
What are some complications that can occur during or after hemodialysis?
-Complications can include loss of vascular access due to clotting or stenosis, infection of the vascular access, bleeding or hemorrhage, hypotension, muscle cramps, nausea and vomiting, and disequilibrium syndrome.
Why is it important to monitor a patient's vital signs and labs before, during, and after hemodialysis?
-Monitoring vital signs and labs helps ensure the patient's safety by detecting any changes that could indicate complications, allowing for timely interventions and adjustments to the dialysis process.
What is the role of anticoagulants like Heparin during hemodialysis?
-Anticoagulants like Heparin are used to prevent blood clotting at the needle tips during hemodialysis, ensuring the continuous flow of blood through the dialysis machine.
What should patients avoid doing after getting a fistula or graft surgery?
-Patients should avoid lifting heavy objects, wearing constrictive clothing or jewelry near the access site, and sleeping on the side of the surgery to prevent complications and ensure proper healing.
Outlines
😀 Introduction to Hemodialysis
The video begins with an introduction to hemodialysis, explaining why patients need it, what it is, and how nurses care for patients undergoing the procedure. Hemodialysis is described as a treatment for patients with kidney dysfunction, where blood is cleaned by a dialyzer to remove waste and restore balance. The importance of the procedure is emphasized, as it replaces the kidney's function of continuously cleaning the blood. Patients typically attend three sessions per week, each lasting around three to five hours.
🌡️ Vascular Access for Hemodialysis
The paragraph discusses the necessity of vascular access for hemodialysis, which can be achieved through a fistula, a graft, or a temporary central venous catheter. A fistula is created by surgically connecting a vein and an artery, resulting in increased blood flow. Grafts involve using a synthetic vessel to connect an artery and a vein. The paragraph also highlights the importance of assessing these access points for functionality, as well as educating patients on how to care for them and what warning signs to look out for, such as changes in pulse, sensation, or color in the hand.
📝 Pre-Dialysis Assessment and Consent
This section covers the pre-dialysis procedure, starting with obtaining patient consent. It emphasizes the importance of assessing the patient's vascular access point, vital signs, and lab work. The patient's weight is also monitored to ensure there are no significant fluid changes during the dialysis process. The paragraph advises holding certain medications that could affect blood pressure or be quickly removed by dialysis, such as diuretics, vasodilators, and some vitamins.
💉 Initiating the Dialysis Procedure
The paragraph explains the process of preparing the patient for dialysis, which includes inserting two needles into the vascular access point. The focus during the dialysis procedure is on monitoring the patient's vital signs, lab work, and the functioning of the dialysis machine. The patient is also educated on warning signs to report, such as headache, nausea, dizziness, or muscle cramps. The use of anticoagulants like Heparin is mentioned, and the importance of having protamine sulfate available in case of bleeding complications is highlighted.
🩸 Post-Dialysis Care and Complications
The post-dialysis procedure involves removing the needles, checking for bleeding, and comparing pre- and post-dialysis vital signs and lab results. The patient is advised to monitor for any changes or warning signs after the procedure. The paragraph also discusses potential complications, such as loss of vascular access due to clots or stenosis, infection, bleeding, hypotension, muscle cramps, and nausea and vomiting. The importance of addressing these issues promptly to prevent further complications is emphasized.
🧠 Dialysis Disequilibrium Syndrome
The final paragraph addresses dialysis disequilibrium syndrome, a potential complication that can occur, especially during the first dialysis session. This condition arises when the patient's fluid and electrolyte levels change rapidly, which can lead to cerebral edema and increased intracranial pressure. Symptoms include nausea, vomiting, dizziness, and a drop in blood pressure. The paragraph stresses the importance of recognizing and addressing this emergency promptly to prevent severe neurological consequences.
