Effects of Continuous Haemofiltration vs Intermittent Haemodialysis on Microcirculatory Parameters in Septic Shock

Not Applicable

• Conditions: Septic Shock
• Interventions: Device: muscle microdialysis

• Registration Number: NCT02962700
• Lead Sponsor: Military Hospital of Tunis

Brief Summary

The aim of the study was to investigate whether CVVH, in comparison to intermittent haemodialysis (IHD), is able to improve regional perfusion in septic shock patients studied by muscle microdialysis

Detailed Description

A prospective, randomized, clinical study ,including septic shock patients with acute renal failure, aged over 16 years. Patients were randomized to receive either CVVH or IHD for renal replacement therapy. Intermittent haemodialysis was carried out during the first 4 h at day 1 and day 2 of the study period. Systemic haemodynamics and interstitial tissue concentrations of lactate, pyruvate, glucose and glycerol were obtained at baseline, 6, 12,18 and 24 hours after initiation of renal replacement by using muscle microdialysis.

Group	Intervention	Description
CVVHF	muscle microdialysis	CVVHF for 48 h interstitial tissue concentrations of lactate, pyruvate, glucose and glycerol were obtained at baseline, 6, 12,18 and 24 hours after initiation of renal replacement by using muscle microdialysis.
IHD for 4 hours	muscle microdialysis	Intermittent haemodialysis was carried out during the first 4 h at day 1 and day 2 of the study period. Interstitial tissue concentrations of lactate, pyruvate, glucose and glycerol were obtained at baseline, 6, 12,18 and 24 hours after initiation of renal replacement by using muscle microdialysis.
