![]() ![]() Available clinical trials at present do not provide a basis for recommending one catheter type over another in this setting. But the quality of studies was poor, and sample sizes were too small to draw valid conclusions about many complication rates. In these studies, no significant difference was found in catheter placement difficulty and misplacement, catheter-related infections or blood clots, other serious complications, or rate of infant mortality. Is chest radiography necessary after uncomplicated insertion of a triple-lumen catheter in the right internal jugular vein, using the anterior approach AU. ![]() The double-lumen catheters, however, clogged, leaked, and broke more often. All three trials found that use of a double-lumen catheter lowered the number of additional venous placements needed during the first week of life. None of the studies used triple-lumen catheters. Three clinical trials involving/completed by 113 babies were identified that compared double-lumen catheters to single-lumen catheters. This could increase blockage and blood clot risks. The channel diameter is generally narrower in ML-UVCs. Complications associated with UVCs are also a consideration. It seems logical that use of ML-UVCs would lower the need for additional venous lines, but this needs confirmation. With more than one channel, multi-lumen umbilical venous catheters (ML-UVCs) can provide access for multiple purposes: for instance, administration of nutrition, blood products, or therapeutic drugs. These tubes into the body can have a single channel (lumen) or they can have two or three channels (multiple lumens). Umbilical venous catheters (UVCs) are frequently used in newborn infants. ![]()
