Why do you need to remove epidural catheter first before removing foley bag catheter?
It is imperative for the effects of the epidural to wear off beofre the foley catheter is discontinued. The last area of the body to resolve the effects of the epidural is the sacral/perineal area, which innervate the bladder. The patient may not be able to sense that his/her bladder is full and may become distended (and uncomforatble) as a result. It may save a reinsertion if taken out too early.
