Abstract:
Hemodialysis (HD) is a treatment with a significant environmental impact. One dialysis cycle is equivalent to the daily consumption of 3.5-4 people, and the average annual electricity consumption of a center is equivalent to that of approximately 2.5-3 households (9 kWh/day per household). The carbon footprint (kg CO2 equivalent) measures direct and indirect greenhouse gas emissions and is influenced by the production of the various materials used, their transport, patients, and healthcare personnel. In this context, it is necessary to understand the real impact of each center on the environment and act sustainably. The aim of this review is to analyze the environmental footprint generated by dialysis, rethink processes, and propose management strategies to provide tools applicable to any unit to reduce the negative impact of this activity. Each center must measure and monitor indicators, set its own standards, design improvement plans, and carry out annual monitoring in a multidisciplinary manner.

Dialysis
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...
Renal Tubule and Collecting Duct
Proximal Convoluted Tubule (PCT):
The PCT is the initial segment of the renal tubule, extending from the Bowman's capsule that encloses the glomerulus. Its convoluted structure and microvilli-lined cells increase the surface area for reabsorption. The PCT reabsorbs glucose, amino acids, sodium, and water from the filtrate, ensuring essential...

Factors Affecting Renal Clearance: Renal Impairment
One condition associated with renal failure is uremia. Uremia is characterized by impaired glomerular filtration and fluid accumulation in the body. This condition hinders the renal clearance of drugs, resulting in drug accumulation and potential...
Renal Failure: Dose Adjustments
Reduced renal clearance and elimination rate are common outcomes of renal impairment. These alterations lead to a prolonged elimination half-life and an altered apparent volume of distribution for drugs. As a result, dosage adjustments are typically necessary to maintain optimal drug levels in the body.
However, dosage adjustments...
