A Randomized Comparative Study Of IJV Cannulation By Anatomical Landmark Technique Versus USG Guided Technique Via Posterior Approach At S.M.S. Medical College , Jaipur.

Central venous cannulation is a very commonly performed procedure in perioperative period and ICUs. The common vessels used are Internal Jugular Vein, Femoral Vein and Subclavian Vein.

Three approaches can be used for IJV cannulation namely, Anterior, Central and Posterior. Central approach is the most commonly used but comparatively Posterior approach is found to be significantly better in prevention of complications.

The IJV cannulation will be done via Posterior approach comparing two techniques- Anatomical landmark based technique versus USG guided technique.

Patient is taken in OT. NBM status, PAC, written and informed consent will be checked. Patient demographic data are taken like age, sex, BMI,NIBP.

Routine vital monitors are attached for ECG, SpO2, EtCO2, Entropy, Peripheral IV line.

After randomization patients will be allocated in two groups.

Baseline characteristics are noted such as HR,SBP,DBP,MBP(invasive).

IJV cannulation via posterior approach will be done by conventional anatomical landmark method or USG guided method.

Variables will be noted such as first attempt success rate, number of attempts, skin puncture to flashback time, flashback to catheter insertion time, total procedure time.

Complications if any such as posterior wall puncture, carotid artery puncture, hematoma formation are noted.

Statistical analysis is done using appropriate tests and software and conclusions are drawn.
