Summary
Repeated physical function tests like SPPB and grip strength are appropriate for older adults on dialysis. These assessments help track changes in mobility and daily living activities over time.
Area of Science:
- Gerontology
- Nephrology
- Rehabilitation Medicine
Background:
- Physical function is crucial for independence in older adults.
- Routine physical function assessment is lacking in older adults undergoing dialysis.
- Maintaining physical function is vital for quality of life in this population.
Purpose of the Study:
- To evaluate the appropriateness of repeated physical function measurements in older adults receiving dialysis.
- To assess the feasibility and utility of the Short Physical Performance Battery (SPPB), handgrip strength, and activities of daily living (ADLs) in this cohort.
Main Methods:
- Prospective study involving 37 community-dwelling adults aged 65+ receiving in-center hemodialysis.
- Measurements included SPPB, handgrip strength, and Katz and Lawton ADLs at baseline and 3-month intervals up to 6 months.
- Evaluated completion rates, test effects, and clinically meaningful changes.
Main Results:
- 37 participants were enrolled (67% enrollment rate); retention was 74% at 6 months.
- Measurements were well-tolerated, with minimal participant non-completion.
- Clinically meaningful changes in SPPB, grip strength, and gait speed were observed at 3-month intervals for some participants.
Conclusions:
- The Short Physical Performance Battery (SPPB), handgrip strength, and gait speed are appropriate for interval physical function assessment in older adults on hemodialysis.
- These measures can effectively track changes in physical function over time in this population.
- Further research should address geographic and ethnic diversity.

517
The nursing management of a patient undergoing hemodialysis includes several critical steps, starting with a thorough assessment before the procedure.Before the Hemodialysis ProcedureFirst, record the patient's vital signs—blood pressure, heart rate, respiratory rate, and temperature—to establish a baseline. This baseline is essential for detecting conditions such as hypotension that could impact the patient's response to dialysis. Document the patient's pre-dialysis weight, as this...

387
DialyzersA hemodialysis (HD) dialyzer is a plastic cartridge containing thousands of parallel hollow fibers, which serve as semipermeable membranes. These fibers are typically made from cellulose-based or other synthetic materials. During HD, blood is pumped into the top of the cartridge and distributed among these fibers. Simultaneously, dialysis fluid, known as dialysate, is introduced into the bottom of the cartridge, bathing the outside of the fibers. Across the semipermeable membrane,...

01:25Hemodialysis I: Introduction
871
Hemodialysis (HD) is a medical treatment that artificially removes waste products, excess fluids, and toxins from the blood when the kidneys are no longer able to perform these functions effectively. In this process, blood is filtered through a semipermeable membrane, allowing for the selective removal of waste while preserving necessary components like blood cells and proteins. Hemodialysis is typically performed in patients with end-stage renal disease (ESRD) or severe kidney...

01:18Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Excretion
163
In geriatric patients, renal physiology undergoes significant changes, including diminished renal blood flow and a lower glomerular filtration rate (GFR), leading to alterations in medication clearance. Drugs such as aminoglycoside antibiotics, lithium, and digoxin, which rely on glomerular filtration for removal from the body, particularly impact pharmacokinetics. These drugs tend to have slower clearance rates in older adults, necessitating careful dosage considerations.Evaluation of renal...

449
Peritoneal dialysis, or PD, utilizes the peritoneal membrane as a filter to eliminate excess fluid and waste products. Effective nursing management is essential for ensuring patient safety, preventing complications, and promoting optimal function of the peritoneal dialysis process.Assessment and MonitoringNurses must thoroughly assess the patient before, during, and after each dialysis session. Regular monitoring includes vital signs, daily weight, fluid intake and output, and laboratory values...

Renal failure occurs when the kidneys lose their ability to filter waste products from the blood effectively. It can be classified into two types: acute renal failure (ARF) and chronic renal failure (CRF).
Acute kidney injury develops suddenly and can be caused by pre-renal causes (e.g., hypovolemia, shock), intrinsic renal causes (e.g., acute tubular necrosis), or post-renal causes (e.g., urinary obstruction). In contrast, chronic renal failure progresses gradually over time and is often...
