About this trial

This study aims to investigate whether the Internal Jugular Vein Collapsibility Index (IJV-CI), measured via ultrasonography, can predict hypotension (low blood pressure) that occurs after the induction of general anesthesia. Researchers will measure the diameter of the internal jugular vein in patients before surgery and compare these measurements with the blood pressure changes during the first minutes of anesthesia. The goal is to determine if IJV-CI can be used as a reliable, non-invasive tool to identify patients at higher risk of developing anesthesia-induced hypotension.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Patients aged 18-65 years.

Patients with ASA (American Society of Anesthesiologists) physical status I, II, or III.

Patients scheduled to receive general anesthesia.

Patients scheduled for elective laparoscopic cholecystectomy.

Disqualifiers

Patients with obesity (Body Mass Index > 35 kg/m²).

Patients with Atrial Fibrillation or other serious cardiac arrhythmias.

Patients with a history of neck surgery or any pathology preventing Internal Jugular Vein (IJV) measurement.

Patients with advanced heart failure (Ejection Fraction < 40%).

Trial population

The study population consists of adult patients aged 18-65 who are scheduled to undergo elective laparoscopic cholecystectomy under general anesthesia. Participants will be selected from patients who meet the ASA I-III physical status criteria. The study focuses on evaluating pre-induction internal jugular vein characteristics using routine clinical monitoring data in a perioperative setting.

Treatments tested in this trial

IJV-CI Measurement
Diagnostic test
Pre-induction Internal Jugular Vein (IJV) measurement will be performed using a linear ultrasound probe (5-12 MHz) while the patient is in the supine position. The IJV will be imaged in the transverse plane at the level of the cricoid cartilage. During spontaneous breathing, the maximum and minimum diameters of the vein will be recorded. The Collapsibility Index (IJV-CI) will be calculated using these measurements. This non-invasive assessment is performed immediately before the induction of general anesthesia to evaluate its predictive value for post-induction hypotension.

Treatment groups

42 Participants

are divided into 2 treatment groups

Group A: Hypotensive Group1 intervention

Group B: Non-hypotensive Group1 intervention

Trial outcomes

Primary outcomes

Internal Jugular Vein Collapsibility Index (IJV-CI)

Hypotension is defined as a decrease in Mean Arterial Pressure (MAP) of more than 20% from the baseline value. The predictive value of pre-induction IJV-CI for this occurrence will be assessed.Measurements will be recorded at 0, 1, 2, 3, 5, 7, 9, and 10 minutes following induction, but will stop if surgical incision occurs earlier than 10 minutes

Time frame

Baseline (pre-induction) and every minute up to 10 minutes following induction or until surgical in
