Objective:
To compare the therapeutic efficacy of immediate versus delayed renal replacement therapy (RRT) in septic patients undergoing continuous RRT.
Methods:
We retrospectively analyzed 98 septic patients who received continuous RRT between August 2021 and January 2023. Patients were divided into two groups: RRT group (n=50, immediate RRT) and delayed RRT group (n=48), where RRT was delayed by 48 hours in the absence of renal function recovery. Demographic data, comorbidities, vital signs, laboratory results, Acute Physiology and Chronic Health Evaluation (APACHE) II scores, Sequential Organ Failure Assessment (SOFA) scores, and follow-up details were compared between the two groups.
Results:
The RRT group showed significantly lower serum interleukin-6 and creatinine levels at 1, 3, and 5 days of treatment (P=0.006, P=0.021, P=0.007; P=0.016, P=0.006, P=0.021, respectively) compared with the delayed RRT group. Additionally, the RRT group had shorter ICU stays, reduced duration of mechanical ventilation, and lower total treatment costs (P=0.016, P=0.003, P=0.029). Post-treatment, the RRT group exhibited significantly lower APACHE II and SOFA scores (P=0.031, P=0.018), a shorter average ICU stay (P=0.009), and a lower mortality rate (P=0.018) than the delayed RRT group.
Conclusion:
Immediate RRT in septic patients undergoing continuous RRT significantly reduces inflammatory markers, accelerates patient outcome, and decreases short-term mortality compared to delayed treatment.

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...
01:11Renal 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...

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...
