Conditions: Medical and Surgical,

Registration Number: CTRI/2025/05/086922

Lead Sponsor: Department of anaesthesia Sawai Man Singh Medical College and Attached Hospitals

Brief Summary: Central venous catheterization is a fundamental procedure in modern medical practice widely used in critical care and perioperative settings .A total of 60 patients requiring Right Internal Jugular Venous cannulation for central venous access , either for elective surgeries or in the ICU were enrolled in the study . Patients were randomly allocated in two groups : Group A ( 30), who underwent USG guided IJV cannulation using Modified Pere’s Height formula and Group B ( 30) , who underwent USG guided IJV cannulation using the Landmark Method . The procedure was performed under aseptic precautions with sedation administered as per protocol . A 7cm , 18 G needle was used for venous puncture followed by J-tip guidewire insertion and a 16 cm , 7 Fr triple lumen catheter was placed according to the allocated technique . Post procedural chest X-ray was performed to determine the catheter tip position relative to the carina and the distance between them was measured . The collected data were systematically analysed and compared between the two groups to assess the accuracy of catheter tip placement , the mean distance from the carina and the incidence of complications , thereby determining the efficacy and safety of both techniques for optimal positioning of the R ight IJV catheter
