“…Although the literature contains studies that compared the Dunn method with the Shukla-Ferrara formula, and Shukla-Ferrara formula with modified Shukla-Ferrara formula, no study has compared the three methods together (6,7). In our study, the three methods were compared together.…”

“…The most appropriate position for an umbilical venous catheter tip position is considered as the junction of the inferior vena cava and right atrium (6,7,(9)(10)(11). This regions corresponds to the T9-10 range on anterior-posterior chest radiographs.…”

“…The position of placement of the catheters, which proceeded along the vertebral column and were specified with anterior-posterior chest radiograph, was considered appropriate when it was between the 9th and 10th thoracic vertebrae (T9-10), "too high" when it was above T9 and "too low" when it was below T10 (6,7). Catheters that directed to the portal or splenic veins were defined as having an abnormal position.…”

“…There is no definite rule related with how far umbilical catheters should be inserted in the umbilical vein; different methods including the Dunn method, Shukla-Ferrara, and modified Shukla-Ferrara formula are used (4)(5)(6). Selection of the most correct and feasible among these methods is very important in terms of decreasing the risk and frequency of complications.…”

Aim: Central venous access is frequently provided by way of umbilical venous catheter placement in critically ill newborns. This study compared the methods of Dunn, Shukla-Ferrara, and Revised Shukla-Ferrara in determining the appropriate insertion length of umbilical vein catheters. Material and Methods:This prospective observational study was carried out in 121 newborns with umbilical venous catheter, group 1 (n=41) used Dunn method, group 2 (n=40) used the Shukla-Ferrara formula, and group 3 used revised Shukla-Ferrara formula (n=40). Catheter tip position was evaluated with an anterior-posterior chest radiograph after insertion of the umbilical venous catheter. The ideal position for the umbilical venous catheter was defined as the catheter tip being visible between the 9 th and 10 th thoracic vertebrae on an anterior-posterior chest radiograph. The position of the umbilical venous catheter was considered too high if the tip of the catheter was higher than the 9 th thoracic vertebra and too low if the tip was below the 10 th thoracic vertebra. The following data were collected: appropriate, inappropriate (low, high) placement, and complications of umbilical venous catheterization. Results:In the Shukla-Ferrara group, 53% (17/32) of umbilical venous catheters were placed directly in the appropriate position, compared with 40% (12/30) in the revised Shukla-Ferrara group and 38% (11/29) in the Dunn method group. Umbilical venous catheter-related complications developed in two patients, thrombus in one, and catheter-related blood stream infection in the other. Conclusions:This study showed that the Shukla-Ferrara formula is more accurate in predicting the insertion length for umbilical venous catheters, though statistical significance was not found. Further studies with larger samples are needed on this topic. (Turk Pediatri Ars 2017; 52: 35-42)
