Trial Review

Please note the ANZCTR will be unattended from Friday 20 December 2024 for the holidays. The Registry will re-open on Tuesday 7 January 2025. Submissions and updates will not be processed during that time.

Study type
Interventional
Description of intervention(s) / exposure
One hundred twenty intensive care patients who were intubated and mechanically ventilated were enrolled in the study. Patients were randomly divided into four groups, each consisting of 30 patients.Group I: Control group: Supine position,Group II: 10 degree Trendelenburg position,
Group III: 50 degree passive leg elevation position,
Group IV: 10 degree Trendelenburg position plus 50 degree passive leg elevation position. For all patients, transverse and vertical length, depth, and surface of the internal jugular vein were measured first in the supine and then in the intervention position.Anterior-posterior and transfer diameter, cross sectional area (CSA) and depth were calculated by the same anesthesiologist from the recorded internal jugular vein images. CSA was calculated by the planimeter method.
For depth measurement, the distance from the skin surface to the anterior wall of IJV was measured.After giving the position for the intervention (internal juguler vein catheterization) the chronometer was started. If the time to the vein puncture was more than 20 minutes or any complications occurred during the procedure, that patient was not included in the study.

Outcomes
Primary outcome [1] 291482 0
After giving the position for the intervention, the chronometer was started. To determine the extent of the increase in internal jugular vein (IJV) size(Anterior-posterior and transfer diameter, cross sectional area (CSA) and depth ) in the patients who received the Trendelenburg position, passive leg elevation, or both for is assessed via USG. IJV size were calculated by the same anesthesiologist from the recorded internal jugular vein images. CSA was calculated by the planimeter method.
For depth measurement, the distance from the skin surface to the anterior wall of IJV was measured.
Timepoint [1] 291482 0
Primary timepoint was assessed immediately after internal jugular vein catheterization.
Secondary outcome [1] 306878 0
To investigate the effect of this increase in IJV size on the success of the first attempt at catheterization.The success of the first attempt at was assessed as observation by the the medical team performing the internal jugular vein catheterization..
Timepoint [1] 306878 0
Secondary timepoint was assessed immediately after internal jugular vein catheterization
Secondary outcome [2] 307070 0
To investigate the effect of this increase in IJV size on mechanical complications such as arterial puncture, hematoma, pneumothorax...etc. Mechanical complications ( arterial puncture, hematoma.) was assessed by observation by the the medical team performing the internal jugular vein catheterization. Pneumothorax was assessed by chest X-ray in suspicious patients after internal jugular vein catheterization.
Timepoint [2] 307070 0
Mechanical complications (arterial puncture, hematoma.) was assessed immediately after internal jugular vein catheterization.Pneumothorax was assessed by chest X-ray in suspicious patients within 1 hours after internal jugular vein catheterization

Eligibility
Key inclusion criteria
Intensive care patients who were intubated and mechanically ventilated were enrolled in the study. Patients requiring catheterization, with BMI <30 kg/m2 and blood pressure >90/60 mmHg, who were hemodynamically stable.We enrolled patients, ARDS, postoperative
respiratory failure, neuromuscular disease, pneumonia,
cerebrovascular accident, metabolic disease,
organophosphorus poisoning and catheterization
was performed for the purpose of intravenous fluids,
total parenteral nutrition
and hemodynamic monitoring.
Minimum age
16 Years
Maximum age
80 Years
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
Patients requiring immediate catheterization, with BMI >30 kg/m2 and blood pressure <90/60 mmHg, who were hemodynamically instable, receiving vasoactive medications, who had coronary artery disease, gastric reflux, elevated intracranial pressure, previous catheterization at the same site that would make the intervention difficult for venous cannulation, pacemaker, skeletal deformity, and untreated coagulopathy (INR >2, APTT >1.5x higher, platelet count <50,000/mm3).
