CATHETERS AND DRAINS



CATHETERS
The Foley catheter is a plastic two-lumen tube with an integral inflatable balloon. The balloon is inflated via a small channel.
Suprapubic cystostomy is an alternative way of draining the urinary bladder. The Malecot catheter is well suited for this purpose. It is a rubber or latex tube with wings at the tip. The de Pezzer catheter is based on a similar principal except that instead of wings, it has a bulbous end that can be straightened and recoiled back when the wire introducer is removed.
The catheters used are as follows:
·        Foley
·        Gibbon
·        Malecot
·        De Pezzer
·        Tiemann
Catheter is a tube designed for relieving retention of urine.
·        The tip is blunt and closed
·        There is one opening above the tip.
·        The upper end is open.
·        It can be made of rubber or latex rubber.
How is the catheter introduced?
·        The catheter is sterilized.
·        The area around the penis, glans, scrotum and groin is cleaned with Savlon.
·        The surgeon washes hands and wears sterile gloves.
·        The area is draped with the sterile towel.
·        The tip is dipped in sterile lubricant.
·        The catheter is introduced into the bladder and the urine collected in sterile kidney tray.
DRAIN
The different types of drain in use are as follows:
·        Secured tube
