Techniques for implantation and confirmation of proper position vary among different centers. The article presented different techniques for sonographic guided puncture of the target central vein and confirmation of the proper position of tunneled catheters. Methods:This was an observational study with a single crossover phase, in which operators initially used the open cut down technique and subsequently converted to the ultrasound guided technique. Internal jugular vein (IJV) was used in all cases. Results:In ultrasound guided group, TIDs were inserted in 121 cases while ETCs were inserted in 13 cases. Ultrasound was successful in guiding IJV puncture from the first trial in all cases and in guide-wire localization in the right atrium in 132 cases. There were no reported cases of hematoma, pneumothorax, hemothorax, catheter malposition or surgical-site infection (SSI) in the perioperative period. In the open cut down group, TIDs were inserted in 119 cases. Two patients developed post operative hematoma and one of them developed SSI. The mean time of ultrasound guided TIDs was (30.04 ± 1.1) minutes which was significantly lower than the mean time of cases done by the open cut down technique (45.4 ± 3.1) minutes (P < 0.0001). Conclusion:Ultrasound guidance is helpful for insertion of TIDs and ETCs in the IJV in pediatric oncologic patients. It minimizes the need for open cut downs and fluoroscopy.展开更多
