Ultrasound-guided external jugular and femoral arterial cannulation for juvenile swine.

Central venous and arterial access through minimally invasive techniques has been described in adult pigs. This article demonstrates success in juvenile animals. Using ultrasound guidance and the modified Seldinger technique, 5 Fr/15 cm single-lumen central venous catheters and 20 Ga 4.5 cm femoral arterial catheters were placed in six Yorkshire cross-bred swine. All six cases had no loss of venous catheter patency or infection during the 96-hour follow-up period. Arterial catheters remained patent, and no significant bleeding was noted after removal.
