title: Postoperative deep body temperature rhythm.
abstract: The postoperative deep body temperature rhythms of fifteen patients who received aorto-coronary bypass surgery (group I), and of seven patients who received non-cardiac major surgery (group II), were studied. Postoperative patients, especially those who received aortocoronary bypass surgery, showed greatly disturbed deep body temperature rhythm. There existed infradian and ultradian rhythm in both groups, and there existed two patients in group I who did not show sinusoidal rhythm. The patients of group I also showed a longer period of rhythm than did those of group II. The mesor and amplitude of the patients in group I showed a greater individual variation than did those in group II. The acrophase of both groups deviated widely. The patients who underwent cardiac surgery needed a longer time for temperature rhythm recovery than did those who underwent general surgery.
