Midwife struck off over records.
Sylvia Esack was kicked out of the nursing profession after a Nursing and Midwifery Council (NMC) panel heard she failed to carry out the appropriate checks on two separate patients.
On one occasion she then covered her tracks by falsifying the signature of another member of staff on the drug chart.
During the hearing the NMC panel said she was no longer fit to practice as a midwife following the allegations, which date back to 2004 when she was employed as a staff midwife on ward 31 at James Cook University Hospital.
A report from the panel at the NMC said: "The cumulative effects of the matters found proved against the registrant amounted to a serious departure from the appropriate standards of a midwife and there could be a continuing risk to patients if the registrant was allowed to remain on the register, should she attempt to return to practice at some time in the future."
The panel found that on two separate occasions in August 2004 and September 2008 Esack failed to record she had administered Temazepam and Venofer to patients.
On one occasion Esack, who has been a registered midwife since 1969 and a registered nurse since 1967, admitted that she had failed to check a controlled drug and falsified a signature on the drug administration chart.
The report said: "The panel regards the cumulative effect of the registrant's proven failings very serious. Accurate record keeping is a vital part of the everyday work of a nurse and midwife.
"Unless a nurse or midwife can be relied on to maintain accurate records, patient safety is bound to be put at risk."
The panel heard Esack's employers had made strenuous efforts to improve her drug administration and her record keeping between the two incidents.
But despite supervised practice a third error was made in November 2007.
In that incident she incorrectly calculated and administered the drug Oromorph to a young baby.
The panel decided a striking off order was the only action to be taken in this case.
