What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting This study
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This study looks at whether a non-invasive device can predict low blood pressure after anesthesia in adults having a throat exam. Researchers will measure blood flow indices before and after anesthesia in 110 participants. The goal is to see if these measurements can warn doctors ahead of time, helping prevent complications.

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

The study population will consist of adult patients aged 18-75 years with ASA physical status I-III who are scheduled to undergo elective diagnostic direct laryngoscopy under general anesthesia at the Department of Anesthesiology and Reanimation and the Department of Otorhinolaryngology of Gaziantep University Faculty of Medicine Hospital. Patients meeting the eligibility criteria and providing written informed consent will be consecutively enrolled. The study will include patients undergoing routine perioperative monitoring, and non-invasive hemodynamic parameters such as plethysmographic variability index (PVI) and perfusion index (PI) will be recorded during the peri-induction period.
