[Anesthesia using high doses of fentanyl in coronary patients subjected to myocardial revascularization. Comparison of 2 administration methods]. / Anestesia con fentanyl ad alti dosaggi nei pazienti coronaropatici sottoposti ad intervento di rivascolarizzazione miocardica. Confronto tra due metodiche di somministrazione.

Eighteen patients to be submitted to heart surgery for myocardial revascularization have been considered. The patients were subdivided into two groups, A and B, and a high dose morphinic was administered for the induction and maintenance of the anaesthetic without further analgesic and/or narcotic supplement. The haemodynamic data obtained pointed to excellent stability in patient cardiocirculatory condition: preservation of IC within acceptable values was very interesting, owing to the fact that the high dose morphinic employed triggers very limited myocardiodepression. To conclude, the anaesthesiological techniques adopted seemed reliable and sufficiently protective with regard to exaggerated hyperdynamic responses to algogenic stimuli that trigger harmful haemodynamic conditions in coronary patients.
