Randomized Controlled Trial
Straight-tip guidewire versus J-tip guidewire for central venous catheterisation in neonates and small infants: A randomised controlled trial.
Central venous catheterisation in neonates and infants is challenging because of the small size of the vessels. The curve of the J-tip guidewire causes difficulty when inserting because of the larger radius and the tilted angle of the J-tip. ⋯ In neonates or infants weighing less than 5 kg, central venous catheterisation using a flexible straight-tip guidewire can improve the first-attempt success rate compared with a J-tip guidewire.
