Rates of hypoxemia and hypotension during prehospital RSI performed by London HEMS are relatively low. They are less than that found in previous studies of prehospital RSI and are similar to those reported in studies of in-hospital emergency RSI undertaken in the emergency department or ward setting. We therefore conclude that prehospital RSI has an acceptably low complication rate when performed by appropriately trained personnel.

Overnight alcohol related emergency attendances to St Thomas' hospital increased after the introduction of new alcohol licensing legislation. If reproduced over longer time periods and across the UK as a whole, the additional burden on emergency care could be substantial.
