Ultrasound Guidance Improves the Success Rate of Internal Jugular Vein Cannulation: Discussion (2)

The reported incidence of carotid artery puncture is 2 to 11 percent. Fatal exsanguination has been reported. Pneumothorax is a rare complication of internal jugular vein cannulation, but does occur. Such complications can be reduced by measures that reduce the number of needle passes required to cannulate the vein and by eliminating the practice of…

Ultrasound Guidance Improves the Success Rate of Internal Jugular Vein Cannulation: Discussion (1)

Cannulation success rates at the first selected central vascular cannulation site can be expected to be in the range of 60 percent in ICU patients similar to the 65 percent success rate for the control group in our series. Other reported series note higher site success rates; however, these patients received elective cannulation preoperatively and…

Ultrasound Guidance Improves the Success Rate of Internal Jugular Vein Cannulation: Results (2)

Using conventional landmarks, seven of 17 (41 percent; 95 percent confidence interval: 18 to 67 percent) patients were cannulated w ith the first needle pass. Three often (30 percent; 95 percent confidence interval: 7 to 65 percent) patients were cannulated with the second needle pass, none of seven (0 percent; 95 percent confidence interval: 0…

Ultrasound Guidance Improves the Success Rate of Internal Jugular Vein Cannulation: Results (1)

Operator experience was similar for each randomization group: the average number of postgraduate training years of experience for the conventional and ultrasound-guidance groups, respectively, were 6.67 ± 1.95 (SD) vs 6.23 ± 2.01 years. All patients were cannulated with four or fewer passes, using two-dimensional ultrasound, yielding a site failure rate of 0/12 (0 percent;…

Ultrasound Guidance Improves the Success Rate of Internal Jugular Vein Cannulation: Materials and Methods

A Hewlett-Packard 7702A two-dimensional ultrasound unit with 5 Mil/ resolution was used. We affixed a 2.5-cni water hath standoff to a near-focus sinall-parts transducer. Because the ultrasound transducer had to he placed over the internal jugular vein in a sterile field, the transducer was wrapped in a sterile glove using the Following technique. A drop…

Ultrasound Guidance Improves the Success Rate of Internal Jugular Vein Cannulation

Central venous cannulation is necessary in most critically ill patients for urgent or life-saving indications including massive volume resuscitation, administration of vasopressor agents, monitoring central hemodynamic parameters, temporary transvenous pacemaker insertion and administration of total parenteral nutrition. Placement of central venous catheters is most difficult for patients who need it most urgently, particularly those in…
