DD Register

The scheduled drug register is a legal document. After any incident adversely affecting a patient where there is reason to believe that drugs administered may be the cause, the information in the register will be required as evidence. It is therefore essential that all records be accurate. You don't mention your country, but in mine the patient details, prescribing doctor, amount given and the signatures of the persons administering and checking are entered on one line, and the amount discarded on the next line.

Protocols regarding the correct maintenance of registers should be covered by whatever laws exist in your country regarding the storage, issuing, recording and checking of controlled substances. If you google it I'm sure you'll find it.

Obviously, entries are made on the page of the specific ampule used; for example, if an anaesthetist opens a 50ml Propofol and only uses 20ml, the entry will be made on the page for the 50ml vial, as opposed to that for the 20ml ampule; if he gives Pethidine 50mg using a 50mg ampule, and afterwards gives a further 50mg, also using a 50mg ampule, the register must reflect two 50mg ampules administered, as opposed to one 100mg ampule. Otherwise your daily checks will be horribly wrong.
