Abstract:
Impact of volume challenge (VC) on renal hemodynamics and renal function in patients with septic-induced acute kidney injury in addition to transpulmonary thermodilution (TPTD)-derived hemodynamic parameters.Systemic hemodynamic parameters derived from TPTD, Doppler-based resistive index (RI) urine output, creatinine and urea levels were obtained before, after and 24 h after VC.Heart rate (p < 0.045), systolic blood pressure (p < 0.030) and mean arterial pressure (p < 0.001) were significantly altered after VC in VC responders compared to baseline immediately after VC but not after 24 h (p = 0.719; p = 0.576; p = 0.435).TPTD-derived cardiac function parameter cardiac index significantly increased after VC (p < 0.001) as well after 24 h (p < 0.02) in the responder group. Stroke volume index also significantly increased after VC (0.033) in responders immediately after VC, but not after 24 h of VC (p < 0.073). No significant changes could be observed in the non-responder group.Renal RI was not significantly different between VC responders and VC non-responders (p = 0.55) immediately after VC and after 24 h (p = 0.65).Creatinine levels in VC responders significantly decreased after 24 h (p < 0.001). Urine output increased from 400 to 542 ml/d in responders, but not statistically significant (p = 0.09). Vasopressor dose in VC responders was statistically significantly lower after 24 h (p < 0.001) compared to baseline.Responders to VC with septic-induced AKI can benefit from an optimized hemodynamic environment. The resistive index to guide fluid therapy for renal hemodynamic management may be limited by the small magnitude of the changes.
