Use of the ERAS protocol for the perioperative management of open AAA surgery shortened the time before recommencing oral consumption, the postoperative hospital stay, and reduced the medical costs compared to the conventional approach.

The purpose of this study was to compare the intubation time using Smart Care, a knowledge-based system for automated weaning, with that of conventional physician-controlled weaning after off-pump coronary artery bypass (OPCAB) and to determine the efficacy of Smart Care. During 2004, 53 sequential patients were scheduled for isolated coronary artery bypass grafting without cardiopulmonary bypass. Patients were divided into two groups: the Smart Care group (n = 10) and the control group (n = 35). Eight patients requiring hemodialysis and patients undergoing the awake OPCAB method were excluded. The intubation times were 172.6 +/- 51.6 min in the Smart Care group compared with 342.0 +/- 239.0 min in the control group (P = 0.032). No specific complications occurred with this computer-driven expert weaning system. In conclusion, the Smart Care system reduced the duration of mechanical ventilation and the respiratory care workload. This system was effective in the care of patients without complications requiring mechanical ventilation after OPCAB.

BACKGROUND: The effects of high-flow nasal cannula (HFNC) therapy on postoperative atelectasis and duration of oxygen therapy after off-pump coronary artery bypass graft are unknown. The purpose of this study was to compare the effects of HFNC therapy for subjects who underwent off-pump coronary artery bypass graft with the effects of standard oxygen therapy in terms of oxygen requirement and atelectasis. METHODS: This prospective single-blinded randomized, controlled trial included 148 subjects who underwent off-pump coronary artery bypass graft between 2010 and 2015 with HFNC (n ‫؍‬ 72) or without HFNC (standard O 2 , n ‫؍‬ 76). The primary end point was the percentage difference in loss of lung volume between subjects with or without HFNC therapy. Secondary end points included the total amount of oxygen administered and duration of oxygen therapy with and without HFNC therapy. RESULTS: There were significant between-group differences in the percentage loss of lung volume (P < .001), total amount of oxygen administered (P < .001), duration of oxygen therapy (P < .001), and the need for postoperative diuretic therapy (P ‫؍‬ .037). The amount (‫؍‬ 0.569, P < .001) and duration (‫؍‬ 0.678, P < .001) of oxygen administered were correlated with atelectasis volume. CONCLUSIONS: Using HFNC therapy after off-pump coronary artery bypass graft shortened the duration of oxygen therapy and reduced the percentage loss of lung volume and total amount of oxygen administered when compared with standard oxygen therapy.

A 70-year-old male patient had a tumor in the left ventricular apex that was detected by transthoracic echocardiography. He had no clinical manifestations. A diagnosis of benign lipoma was made using the noninvasive fat suppression technique of cardiac magnetic resonance imaging (MRI). Video-assisted surgery was performed to resect the tumor, and the histopathological examination confirmed the diagnosis of lipoma. A small part of the tumor was not resected. The postoperative course was uneventful. No signs of recurrence were detected on transthoracic echocardiography or MRI during a 22-month post surgical follow-up period.
