Continuous Finger-cuff Arterial Pressure Monitoring and Intraoperative Hypotension During Non-cardiac Surgery: the Randomized DETECT II Trial

ClinConnect Summary

The DETECT II Trial is a study looking at whether using a continuous finger-cuff device to monitor blood pressure during surgery can help prevent low blood pressure (called intraoperative hypotension) in patients undergoing non-cardiac surgeries. This trial specifically compares this new method to the traditional way of checking blood pressure, which is done at intervals using an upper-arm cuff. The goal is to see if continuous monitoring can improve patient safety and outcomes during surgery.

To participate in this trial, patients must be 45 years or older and scheduled for certain types of elective surgeries that require general anesthesia. This includes outpatient surgeries lasting at least 30 minutes, or inpatient surgeries for low-to-moderate risk patients lasting at least 60 minutes. However, those who have emergency surgeries, require kidney dialysis, or have conditions that make finger-cuff monitoring unsuitable cannot join. Participants can expect to be monitored continuously during their surgery, which may help their medical team respond more quickly to any changes in blood pressure. Overall, this study aims to enhance the safety of surgical procedures for eligible patients.

Eligibility criteria

• 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)
