Summary

We have compared, in

40

healthy patients, the cardiovascular responses induced by laryngoscopy and intubation with those

produced by insertion

o

a laryngeal mask. Anaesthesia was induced with thiopentone and maintained with enjlurane and nitrous

in

systolic arterial pressure after laryngoscopy and tracheal intubation was 51.3 compared with

22.9
