Can a Hand-Placed catheter keep blood pressure readings steady during robotic surgery?
NCT ID NCT07732296
First seen Jul 28, 2026 · Last updated Aug 06, 2026 · Updated 3 times
Summary
During robot-assisted urologic surgery, the patient's arms are tucked at their sides, which can kink or compress a standard wrist artery catheter, causing inaccurate blood pressure readings. This trial tests whether placing the catheter in the distal radial artery (near the back of the hand or anatomical snuffbox) reduces such problems. Seventy adults scheduled for robotic urologic surgery will be randomly assigned to receive either a conventional wrist catheter or a distal hand catheter. The study will track how often each method leads to catheter dysfunction requiring intervention.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If distal radial catheterization proves more stable, it could reduce the need for troubleshooting or replacement during arm-tucked surgeries, improving patient safety and workflow.
- What could go wrong
- This is a small, single-center study with 70 participants, so results may not apply broadly. The procedure itself carries standard risks like bleeding or infection.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Adults aged 19 years or older * Scheduled to undergo robot-assisted urologic surgery under general anesthesia * Scheduled to have both arms positioned alongside the body in an arm-tucked position during surgery * Considered by the attending anesthesiologist to require intraoperative invasive arterial blood pressure monitoring * Able and willing to provide written informed consent Exclusion Criteria: * Refusal to participate or inability to provide written informed consent * Emergency surgery * Pregnancy or breastfeeding * Lack of decision-making capacity requiring consent from a legally authorized representative * Presence of an arteriovenous fistula for dialysis or unsuitable bilateral radial artery access * Infection, burn, trauma, surgical scar, or severe skin lesion at the intended puncture site * Suspected hand perfusion impairment, including radial artery occlusion, absent radial pulse, severe peripheral vascular disease, or Raynaud phenomenon * Severe coagulopathy or uncorrected bleeding tendency for which radial arterial catheterization is considered inappropriate * Any condition for which the attending anesthesiologist considers study participation inappropriate for participant safety
