For the first time, four London Ambulance "booze buses" have been put into operation in the capital to cope with one of the busiest party nights of the year.
The specially converted mini buses are equipped to deal with every medical eventuality, and are used to take the strain off emergency services dealing with non alcohol-related 999 incidents.
Paramedic team leader Brian Hayes came up with the idea seven years ago.
He said: "It was purely to deal with the increase in the number of alcohol-related jobs we were receiving in London.
"The pressure on the ambulance service, especially on Friday and Saturday nights deemed it necessary.
"Every chair space and every bed space that we have on this vehicle will be ready for somebody who's intoxicated. We've got the vomit bowls for the obvious."
On a normal Friday night just one bus is in operation. Last night there were two in London's West End, one in the City and one in Camden.
Many are taken to an alcohol recovery centre in Soho, but the more serious cases end up in hospital, as do under-18s.
Brian's team picked up a 17-year-old boy on Park Lane.
He said: "He's been out partying with his friends and he's had too much, basically.
"He can't walk any further so we're going to have to take him up to hospital. He's too young for our walk-in centre."
Last year in the 10 days over Christmas 180 patients were treated at the centre.
