Finger cuff may prevent dangerous drops in blood pressure during surgery
NCT ID NCT06753097
First seen Jun 27, 2026 · Last updated Aug 19, 2026 · Updated 2 times
Summary
This study tested whether a continuous finger-cuff blood pressure monitor could reduce episodes of low blood pressure during non-cardiac surgery compared to the standard arm cuff that measures blood pressure every few minutes. The trial included 930 low-to-moderate risk adults having elective surgery. The goal was to see if the continuous monitor helps doctors respond faster to prevent dangerously low blood pressure.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- continuous finger-cuff arterial pressure monitoring device
- What this could lead to
- If successful, this could show that continuous monitoring helps prevent dangerous drops in blood pressure during surgery, potentially improving patient safety.
- What could go wrong
- This is a completed trial, but the results are not yet published. The benefit may be small or not apply to all types of surgery or patients.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
We will include three types of patients: 1. Patients scheduled for ambulatory (outpatient) elective non-cardiac surgery expected to last ≥30 minutes 2. Low-risk patients (ASA I+II) having inpatient elective non-cardiac surgery expected to last ≥60 minutes 3. Moderate-risk patients (ASA III) having inpatient elective non-cardiac surgery expected to last ≥60 minutes We will only include patients who are 18 years or older; who will have general anesthesia; and in whom intermittent arterial pressure monitoring with upper-arm cuff oscillometry is planned. Patients that meet one or more of the following exclusion criteria cannot participate in the trial: * Emergency surgery * Patients on renal replacement therapy * Contraindications for finger-cuff monitoring (e.g., Raynaud disease)
