Ronnie Cormack and John Lehane have given the anaesthetist the means to grade a difficult intubation. Used in conjunction with Malampati's Score, it is an excellent indicator to anaesthetist on how difficult the intubation about to be performed is going to be.


Cormack was born in Burma in 1930 of Scottish parentage. He worked mainly in Bristol, London and Oxford during his career. Lehane was born and educated in Merseyside and then moving to Northwick Park Hospital in the mid seventies. It was here that they wrote the paper on their now famous intubation Grades.285
