Summary

Around 300 million surgical operations are performed globally, and of these, 40 to 50 million are performed in the USA. The perioperative period is characterized by hemodynamic instability and, most importantly, hypotension. Intraoperative hypotension is frequent, and the incidence ranges between 5% and 99% during non-cardiac surgery, depending on the definition.

The aim of the study is determined as the relationship between two different time intervals of measurements and time spent hypotensive under harm thresholds in non-cardiac surgery in adults having non-cardiac surgery. Secondarily, it will be determined if more frequent non-invasive blood pressure measurement use decreases postoperative acute kidney injury. Exploratory, it will be evaluated if more frequent non-invasive blood pressure use causes pain or nerve injury in the arms or not.

Interventions

DIAGNOSTIC_TEST

Blood Pressure Measurement

NIBP measurements will be recorded intraoperatively every 2.5 minutes for the group of 2.5 min. Blood pressure management or every 5 minutes for the other group of 5 min. Blood pressure management after providing randomization before the surgery. A calibrated and time-matched same type of standard anesthetic monitor will be used. The monitor will measure blood pressure and display the mean, systolic and diastolic values. All blood pressure measurements will be discontinued before the PACU transfer. Data will be automatically downloaded from the monitor to a computer using a software interface program.
