Comparing bladder pressure and intestinal oxygen levels in infants

Comparison of Bladder Pressure Versus Regional Intestinal Tissue Oxygenation in Infants

Not applicable Interventional University Children's Hospital, Zurich · NCT05971264

This study is testing how bladder pressure and oxygen levels in the intestines compare in infants during and after certain surgeries to see if these measurements stay stable in different situations.

What this trial studies

This clinical trial aims to compare bladder pressure measurements with regional intestinal oxygen saturation levels in infants undergoing specific surgical procedures. It will utilize near-infrared spectroscopy to assess oxygen levels in the intestines and measure bladder pressure both intraoperatively and postoperatively. The study focuses on infants who are muscle-relaxed and intubated, as well as those who are awake and non-sedated, to determine the stability of these measurements in different conditions.

Who should consider this trial

Good fit: Ideal candidates for this study are infants aged 12 months or younger who are scheduled for laparoscopic pyeloplasty or specific corrective surgeries.

Not a fit: Patients with significant abdominal wall thickness or those requiring additional intestinal surgeries may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve monitoring techniques for infants at risk of intraabdominal hypertension, leading to better patient outcomes.

How similar studies have performed: While this approach is innovative, similar studies have not been widely reported, indicating that this may be a novel investigation.
