Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
Intravenous access in the critically ill trauma patient: a multicentered, prospective, randomized trial of saphenous cutdown and percutaneous femoral access.
To compare the speed of IV access and the rate of infusion for saphenous venous cutdown and percutaneous femoral catheterization. ⋯ Percutaneous femoral catheterization can be performed more rapidly than saphenous cutdown in the critically ill trauma patient with a palpable femoral pulse and allows for more rapid fluid administration. We support the use of a percutaneous femoral line as an acceptable alternative to saphenous venous cutdown in the initial resuscitation of trauma patients.

Randomized Controlled Trial Clinical Trial
Reducing the pain of local anesthetic infiltration: warming and buffering have a synergistic effect.
To compare room-temperature unbuffered lidocaine, warm lidocaine, buffered lidocaine, and warm buffered lidocaine to determine which of the four solutions is least painful during infiltration. ⋯ Skin infiltration with warm buffered lidocaine is significantly less painful than infiltration with room-temperature unbuffered lidocaine, warm lidocaine, or buffered lidocaine.
