Baby monitors and defibrillators were among the other expensive, life-saving items to disappear from wards.

NHS Tayside staff admitted it had "lost" a specialist bariatric bed for obese patients at the former Sunnyside Royal Hospital in 2011. The beds can cost in the region of £7000.

NHS Lanarkshire reported the loss of three expensive pieces of equipment including a £2280 defibrillator, a £1800 blood glucose level monitor and a £1100 flow meter with suction units.

NHS Greater Glasgow and Clyde was one of a number of health boards that said they had not had a single loss or theft of medical equipment in five years.
Scottish Conservative health spokesman Jackson Carlaw said: "It's fairly staggering to think items of such bulk and significance have simply slipped through the net. Given taxpayers' money is at stake here, the NHS really has to be more careful at times. However, staff do not have time to be security guards as well as health professionals."
He added that it was up to hospitals to put in "strong security arrangements".
Margaret Watt, chairwoman of the Scotland Patients Association, said: "Your local Boots, Tesco and clothes stores all have tags and monitors, so why should our hospitals be any different?
"It's simply unacceptable that so many items are either being lost or stolen at a cost to the health board and taxpayer. This money could be spent elsewhere on other vital services."
George Curley, Director of Operations at NHS Lothian, said it takes issues of security seriously. "We are concerned and disappointed when any items are stolen," he added. "We have a robust range of precautions in place to guard against theft and we regularly work with police to safeguard our resources. We also remind staff to be vigilant and patients and visitors to be careful with their possessions and to report incidents.
"All electrical equipment, including memory sticks, is encrypted, to ensure that any patient identifiable data is safe and not accessible."
