Analgesia Nociception Index for Pain Monitoring in Intensive Care Units

• Conditions: Pain; Stress Related Disorder; Intensive Care Unit Syndrome

• Registration Number: NCT05313789
• Lead Sponsor: İstanbul Yeni Yüzyıl Üniversitesi

Brief Summary

The aim of this study is to examine the usability of ANI in patients who will be treated in intensive care unit.

Detailed Description

The aim of this study is to examine the usability of Analgesia Nociception Index in patients who will be treated in intensive care unit ( a- Cardiovascular b- surgical c- internal diseases), mechanically ventilated and lacking communication. The investigators will examine whether the positive inotropic/vasoconstrictor agents will have any effect on Analgesia Nociception Index.

Primary Outcome Measures

Name	Time	Method
Analgesia Nociception Index for pain monitorization	3 Months	The duration between two R waves within heart rate variations (filtering the variations in respiratory cycles). A numeric measure of parasympathetic tonus will be obtained. This variation is between (pΣ) 0 and 100.
