Entonox: too useful to be limited to childbirth?

: Entonox, a nitrous oxide/oxygen gas widely used as an analgesic in child-bith, can be used for other patients undergoing a variety of painful procedures. It is highly effective, safe and easy to use and is under the patient's control. It takes effect within seconds and wears off quickly with no side-effects. It is being used successfully for children as well as adults. Nurses can administer Entonox with suitable in-service instruction, preferably from the local pain service team Portable apparatus is available, similar to that used by midwives in the home and by ambulance staff. There may be situations in general practice or patients' homes where community nurses could use Entonox to relieve pain.
