We plan to compare single person short axis view with two person long axis view
Introduction: The guidelines for the use of bedside ultrasonography in the evaluation of critically ill patients published by the society of critical care medicine recommends short-axis view be used during insertion of central venous catheter (CVC) in internal jugular vein (IJV) to improve success rate1. The long axis view is considered better for cannulations as it helps in preventing posterior wall puncture but in the trials it has been found to be inconvenient for a single user2,3. We hypothesise that if two persons perform long axis cannulations i.e. one person will image the vein while the other punctures it will be equally convenient to single person doing the cannulations in short axis. The advantage we expect to see is lesser complications in long axis group.
Inclusion criteria: Any patient getting admitted to ICU and requiring central venous cannulations.
Exclusion: Lack of consent. Randomization: At a 1:1 ratio, to be achieved using a computer-generated random number sequence for 100 consecutive subjects Study intervention: Eligible patients will be randomized to a short-axis or long axis technique for ultrasound guided IJV cannulations. Ultrasound guidance will be performed dynamically using a single-operator technique for short axis and double operator technique for long axis view. Cannulations and USG is to be carried out by 2 trained Anaesthesiologists.
1. Insertion time: Time taken from 1st puncture of skin to insertion of guide wire into the vein.
2. Total Procedure time: Time from when Ultrasound scan was started to complete suturing of the CVC line.
3. Number of needle sticks: Number of time punctures were done in the skin. Complications were noted as hematoma formation, posterior wall puncture, arterial puncture, extravasations of blood and pneumothorax.
All the times are to be noted by a bedside nurse who is not involved in the trial or knows the study hypothesis.
Statistical Analysis: An intention-to-treat analysis was performed. Insertion time, overall procedure time and number of needle sticks, and will be compared using Mann-Whitney U tests. The success rate and complication rate will be compared using Fisher exact tests. All statistical analyses will be performed with SPSS 20.0

Ultrasonography applying the Doppler effect, with the superposition of flow information as colors on a gray scale in a real-time image. This type of ultrasonography is well-suited to identifying the location of high-velocity flow (such as in a stenosis) or of mapping the extent of flow in a certain region.
Ultrasonography applying the Doppler effect, with velocity detection combined with range discrimination. Short bursts of ultrasound are transmitted at regular intervals and the echoes are demodulated as they return.
Ultrasonography applying the Doppler effect combined with real-time imaging. The real-time image is created by rapid movement of the ultrasound beam. A powerful advantage of this technique is the ability to estimate the velocity of flow from the Doppler shift frequency.
Ultrasonography applying the Doppler effect, with frequency-shifted ultrasound reflections produced by moving targets (usually red blood cells) in the bloodstream along the ultrasound axis in direct proportion to the velocity of movement of the targets, to determine both direction and velocity of blood flow.

Ultrasonography of internal organs using an ultrasound transducer sometimes mounted on a fiberoptic endoscope. In endosonography the transducer converts electronic signals into acoustic pulses or continuous waves and acts also as a receiver to detect reflected pulses from within the organ. An audiovisual-electronic interface converts the detected or processed echo signals, which pass through the electronics of the instrument, into a form that the technologist can evaluate. The procedure should not be confused with ENDOSCOPY which employs a special instrument called an endoscope. The "endo-" of endosonography refers to the examination of tissue within hollow organs, with reference to the usual ultrasonography procedure which is performed externally or transcutaneously.
