Editor—Smith and Jones found out the attitudes of several surgeons to the edict from Sheriff Albert Sheenan in Scotland.1 I suspect, however, that if the same questionnaire had been sent to cardiac surgeons, the response might have been different.
There are essential differences in the significance of intraoperative deaths between cardiac and non-cardiac surgery. In cardiac operations the patients are being kept alive by the heart-lung machine while the surgeon operates on the heart, and it is only at the end of the procedure that an attempt is made to persuade the patient's heart to take over the circulation. After gastric surgery, the patient is not expected to eat a large meal immediately after. Similarly, after lower limb surgery the patient is not expected to jump off the operating table and run back to his bed. In cardiac surgery, however, it is essential that the heart resumes its work immediately at the end of the procedure. Intraoperative deaths occur usually when the heart is unable to do so successfully despite maximal pharmacological and sometimes mechanical support.
Intraoperative deaths therefore suggest that the operation has not been done in a technically perfect way, that the ischaemic period of the heart was too long, or that the heart was not protected adequately during the ischaemic period. All these are the responsibility of the surgeon and not the anaesthetist. It is therefore the surgeon on whom the burden of an intraoperative death tends to fall. Intraoperative deaths in cardiac surgery occur only after the surgeon has tried again and again to wean the patient off the heart-lung machine. This tends to take many hours. These operations are therefore both physically and psychologically draining, and most cardiac surgeons would probably find the advice of the sheriff both appropriate and comforting.
