A novel skin traction method to facilitate ultrasound-guided femoral nerve block in morbidly obese patients

An ultrasound-guided peripheral nerve block is difficult to perform in morbidly obese patients, particularly those who require catheter placement, due to the amount of subdermal adipose tissue [1]. The skin traction method is reportedly useful for central venous catheter placement in pediatric cases [2]. Here, we propose the use of skin traction to perform a peripheral femoral nerve block.
