Travelling such a distance allows adequate time for planning and this should not be wasted. Plan to keep in touch with the tasking agency/coordinator for updates on numbers, ages and clinical condition of casualties. Discuss with them what potential local resources are available. How many nurses and paramedics are there? Where is the next nearest healthcare facility? Are additional regional air medical resources available? In essence, this is a primary tasking as patients are likely to have had little input into their care either before or in the clinic. You should discuss frankly the possibility of this becoming a major incident so the coordinator can look into extraordinary resource utilisation (e.g. military assistance). Finally, use the time en route to prepare by drawing up and labelling appropriate drugs, pre-priming fluid infusion lines and developing a pre-hospital plan with your team members.
