Summary:The specific features of an early postoperative period were studied in 115 patients undergone myocardial revascularization who were divided into 3 groups according to the time of postoperative activation. Group 1 comprised 35 patients in whom tracheal extubation was made in the operating room 30-60 min after the end of the operation. Group 2 included 32 patients extubated 2-8 hours after admission to the resuscitation and intensive care unit (RICU); Group 3 consisted of 48 patients undergone tracheal intubation for more than 8 hours. The patients of this group received traditional anesthesia using ketamine, benzodiazepines, and large-dose fentanyl. The developed combined anesthesia with inhalational and intravenous anesthetics having their better pharmacodynamics, such as isoflurane, diprivan, tracrium, was used in 60.3% of the patients in Groups 1 and 2. The developed type of anesthesia using a high thoracic (T2-T4) epidural blockade as a basic component of anesthesiological maintenance was studied. In Group 2, the preextubation time was twice less than that in a control group (5.2 +/- 0.3 and 10.8 +/- 0.4 hours, respectively, p < 0.05). In groups with early extubation, the incidence of clinically significant cardiovascular disorders was less than that in the controls, which is indicative of better performance of the cardiovascular system. In Group 1, the frequency of reintubations for arterial hypoxemias was 2.8% and that of pneumonias and pulmonary microatelectasis was 2.5 times less as that in Group 3 (9%, p < 0.05). Chills occurred in 6, 4, and 15% of cases in Groups 1, 2, and 3, respectively (p < 0.05). A programme on early activation after aortocoronary bypass surgery could reduce the patients' stay at the RICU on an average by 24 hours without increasing the risk for postoperative complications.
