Q

Management of faecal impaction

A

Q

What is Hirshprungs disease - patient

A

The bowel passes faececs by a squeezing motion, in this condition a part of the bowel is missing the nerve cells that cause this squeezing leading to a build and potentially a blockage of faeces in the bowel

haemolytic uraemic syndrome - check for E.coli 0157 on stool culture
