Official title
Internal Jugular Vein Collapsibility Index as a Predictor of Hypotension After The Induction of General Anesthesia in Geriatric Patients Undergoing Laparoscopic Colorectal Surgeries: A Prospective Observational Study
Overview
The internal jugular vein (IJV) collapsibility index has been proposed as a practical alternative of of the inferior vena cava collapsibility index (IVC-CI), as it is easily accessible using bedside ultrasonography. Several studies have demonstrated a correlation between IJV collapsibility and central venous pressure as well as right atrial pressure.
Interventions
- Other Internal Jugular Vein Collapsibility Index
Assessment of internal jugular vein collapsibility index to predict hypotension after the induction of general anesthesia in geriatric patients undergoing laparoscopic colorectal surgeries.
Primary outcome measures
- Optimal cut-off value of ultrasound guided Internal Jugular Vein Collapsibility Index (percent) (%) to predict post induction hypotension. [Time frame: The first 15 minutes after induction of general anesthesia.]
Eligibility criteria
Inclusion criteria
- Patients aged ≥ 60 years.
- Scheduled for elective laparoscopic colorectal surgeries under general anesthesia.
Exclusion criteria
- Patients' refusal of procedure or participation in the study.
- Severe aortic stenosis, irregular ventricular rhythm (atrial fibrillation or frequent premature ventricular contractions), or any contraindication to perform passive leg raise (PLR).
Criteria are shown verbatim from the registry (in English). Final eligibility is always assessed by the study center.
