Abstract:
In this study, the authors describe a simple, nontraumatic procedure for ultrasound-guided placement and maintenance ofjugular and cephalic vein catheterization. The ultrasound scans were performed with a GE Logiq 400 machine connected to a multifrequency (7-11 MHz) linear-array transducer. To find the cephalic vein, longitudinal and transverse color-Doppler ultrasonographic scans were made of the dorsal surface of the flipper. To find the jugular vein, scans of the midline of the lateral surface of the neck were performed. Once the vein had been located, a 16- to 22-gauge 51-mm needle catheter was inserted into the skin beneath the ultrasound probe, inclined at 15-25 degrees to the skin surface. The successful insertion of the catheter inside the vein was monitored by ultrasound. The authors believe that the procedure described offers a good option for fashioning a simple, nontraumatic, and durable vascular access in sea turtles compared with previously described techniques.
