Filter by:To investigate biomarker reflects systemic or specific organ perfusion well, we are going to the observational comparison study using several hemodynamic monitoring methods in the premature infants. It includes near-infrared spectroscopy (NIRS), pulse oximetry with perfusion index (PI) and pleth variability index (PVI) and functional echocardiography.
Background: After hypotension, oliguria (urine output less than 0.5 mL/kg/h) was the most common trigger to administer fluid bolus in a multinational practice survey in intensive care. The effect of fluid bolus on cardiovascular variables can be very short-lived among patients in shock suggesting that fluid boluses in the optimization phase are unlikely to improve patient-centered outcomes. Moreover, a growing body of evidence suggests a poor renal response to fluid bolus. Objective: To investigate, whether fluid bolus - as a standard of care - improves urine output in oliguric patients compared to a non-interventional follow-up approach without fluid bolus. Design: Investigator-initiated, open, randomized, controlled study Interventions: 1. Intervention group - follow-up without intervention 2. Control group - fluid bolus (500mL of balanced crystalloid over 30 minutes) Randomization: 1:1 stratified according to the site, presence of acute kidney injury, and sepsis Trial size: 130 patients randomized in 2 ICUs
Urine output and urine drain line pressure were monitored while urine was drained into either: 1. Accuryn Urine Output Monitor (Potrero Medical) OR 2. Criticore Monitor (Bard Medical)
The investigators will determine the feasibility, safety and efficacy of intravenous sodium bicarbonate in reducing progression to overt acute renal failure in patients with the systemic inflammatory response syndrome, and low urine output or early acute renal impairment as defined by serum neutrophil gelatinase-associated lipocalin (NGAL).
