After an impedance study

This page from Great Ormond Street Hospital (GOSH) describes how to look after your child at home after an impedance study and how to deal with any problems that might occur.Your child should not feel any lasting effects once the pH impedance probe has been removed.

However, please seek medical advice if your child:

  • Says their throat is sore or feels strange
  • Is reluctant to eat
  • Has a nose bleed
These symptoms should pass also immediately or over the course of the next 24 to 48 hours.

If your child has not eaten or drunk anything during the test, make sure that they eat a large snack before you leave the unit. Your nurse can provide this if you have not brought your child’s favourite with you.

Getting back to normal

Unless you have been advised otherwise

  • Your child can start eating and drinking their usual diet
  • They can re-start any medications that were stopped for the test

Getting the test results

The results of the test will usually be reviewed and available with 10 working days. If you do not have a clinic appointment arranged with the consultant who referred your child for the test, please arrange one. Their number to call will be on the bottom of your last appointment letter.
