Short-axis/out-of-plane Approach Versus Oblique- Axis Approach for US Guided IJV Catheterization in Infants.

Ain Shams University50 enrolled

Overview

The investigators will measure and compare the rate of acute complications, success rate, number of attempts to successful cannulation between ultrasound-guided short axis approach and oblique axis approach during internal jugular venous catheterization in infants.

1. pre-procedure settings: The history will be obtained from patient's parents. Investigations will be checked to all patients as (complete blood picture and coagulation profile) to avoid coagulopathy and thrombocytopenia. All patients will be attached to standard monitoring (blood pressure (non-invasive), heart rate, and pulse oximetry). Groups: Patients will be assigned randomly by using a computer -generated table of random numbers into two groups: * Group A (control group): ( n=25 ): CVL insertion in the right internal jugular vein using ultrasound. The US probe is placed perpendicular to the venous anatomy in the SAX approach. * Group B (comparative group): ( n=25 ): CVL insertion in the right internal jugular vein using ultrasound. The US probe is aligned at 45° angulation?clockwise with the venous anatomy in the OAX approach. 2. procedure Settings: Monitor will be connected and pulse oximetry (SPO2), baseline non-invasive blood pressure (NIBP), heartrate (HR), electrocardiogram (ECG) will be obtained. In this study, we will use US machine with small linear probe with frequency 5 - 10 Hz and the procedure will be held by the most senior Anaesthesiologist experience in pediatric central venous catheterization for at least 3 years. The procedure will be held under aseptic condition, Using US, after GA in OR, the anatomical location and patency of the IJV will be assessed with the patient placed in the Trendelenburg position, with the head slightly rotated to the contralateral side. With all sterile precautions, a 4 french introducer needle mounted on a syringe is inserted into the IJV guided by real time US imaging. Once blood is freely aspirated, the US probe is set aside and the syringe removed from the needle. Then the guide wire will be advanced through the needle into the vessel and the catheter will be advanced using the Seldinger technique after guidewire position is confirmed with US. The guidewire will be then removed. Using US, placement of the catheter in the vein will confirmed following which the catheter will be secured in place using sutures. The position of the CVC wiil be also confirmed by a chest radiograph at the end of the procedure. In the group A, The US probe will be placed perpendicular to the venous anatomy in the SAX approach. In the group B, The US probe will be aligned at 45° angulation with the venous anatomy, and combined with an in plane needle insertion technique. The needle will be advanced from lateral to medial.

Outcomes

Primary Outcomes

Difference in the rate of acute complications between the two groups.

acute complications as posterior venous wall puncture (PVWP) (ultrasonographic identification of the needle tip or guidewire at any site deeper than the posterior wall of the IJV during cannulation attempts), skin and subcutaneous hematoma, arterial puncture (any pulsatile blood reflux through the needle observed during the procedure), pneumothorax, hemothorax and catheter misplacement (catheter tip identified at any place other than the superior vena cava in the control chest radiograph)

Time frame: Post-procedure, through study completion (average 1 year)

Secondary Outcomes

Difference in the rate of first successful cannulation attempt.

first successful cannulation attempt (successful venous puncture and successful smooth insertion of guidewire from the first needle puncture without withdrawal of the needle)

Time frame: Post procedure, through study completion (average 1 year)

the flash time.

time to completion flash time (The time interval between skin puncture and observing blood at the syringe hub)

Time frame: Post procedure, through study completion (average 1 year)

the number of needle redirection.

number of needle redirection (redirection of the needle without complete withdrawal of the needle)

Time frame: Post procedure, through study completion (average 1 year)

unsuccessful cannulation.

unsuccessful cannulation (a cannulation is considered unsuccessful if it had to be performed using an approach that differed from that to which the patient had been initially chosen for and also if the operator was unable to cannulate the vein within 3 attempts)

Time frame: Post procedure, through study completion (average 1 year)
