Is it true or false that Entonox may be used in the following circumstances for analgesia?

True / False

Intestinal obstruction Correct

During myringoplasty Correct

Childbirth Correct

Orthopaedic joint manipulation Correct

Inserting a chest drain for pneumothorax Correct

Explanation

Entonox can diffuse into gas filled cavities. Therefore, it can exacerbate pneumothorax, make intestinal pain worse and make inner ear surgery difficult.

It is useful in childbirth and orthopaedic manipulation as a patient-controlled analgesic via demand valve.
