Assessment of Effectiveness of Continuous Non-invasive Haemodynamic Monitor by Compared to Invasive Blood Pressure and Pulse Oximeter Monitoring on Patients Undergoing General Anesthesia Surgeries for More Than 60 Minutes

NCT ID: NCT06383000

Last Updated: 2024-04-25

Basic Information

• Recruitment Status: NOT_YET_RECRUITING
• Total Enrollment: 55 participants
• Study Classification: OBSERVATIONAL
• Study Start Date: 2024-06-01
• Study Completion Date: 2024-12-31

Brief Summary

The goal of this observational study is to assess whether the continuous non-invasive haemodynamic monitor MOH200 (measuring blood pressure as well as pulse rate) is effective or not in people undergoing general anesthetic surgeries for more than 60 minutes with planned invasive blood pressure and pulse oximeter monitoring.

Researchers will compare blood pressure data derived from MOH200 to the invasive blood pressure (IBP) data to see if the MOH200 is effective to measure the blood pressure of a surgical person. Also, researchers will compare pulse rate data drived from MOH200 to that from the pulse oximeter to see if the MOH200 is effective to measure the pulse rate of a surgical person.

Participants will be asked to be applied with MOH200 monitoring while IBP monitoring and pulse oximeter are applied. And after 30 minutes of the surgery, researchers will monitor the adverse effects occurred on the skin of participants to assess the safety of MOH200.
