BACKGROUND Intermittent delivery of warm cardioplegia provides a bloodless surgical field, but it is clinically important to evaluate the periods of normothermic ischemia. The aims of this study are to compare intermittent antegrade warm blood cardioplegia (IAWBC) with intermittent antegrade cold blood cardioplegia (IACBC) groups in terms of myocardial(More)
BACKGROUND Diabetes mellitus (DM) and systemic atherosclerosis are risk factors for stroke. Although the origins of increased risk are complex, one possibility is that cerebrovascular reactivity is impaired and does not allow the brain to compensate for aberrations in physiology. The current study tested this issue by evaluating mean blood flow velocity of(More)
Tracheobronchial stenting was performed under general anesthesia, with (six patients) or without (two patients) muscle relaxant, in eight patients suffering from carcinoma. All patients had presented preoperatively with dyspnea, exhibiting Hugh-Jones grade 4 or 5. Three patients had been mechanically ventilated before the procedure. The procedure was(More)
We retrospectively examined the changes in hemodynamics, oxygen index and renal function along with the complications in 25 patients who had undergone endovascular stent graft placement (ESG) surgery for abdominal aortic aneurysm. During stent graft placement, mean arterial pressure decreased to 58 +/- 8 mmHg by increasing the dose of anesthetics and/or(More)
We investigated the effects of inversed ratio ventilation by altering the inspiratory:expiratory (I:E) ratio and assessing the time course changes in the intrapulmonary shunting (Qs/Qt) in 14 patients with acute respiratory failure. Stepwise prolongation of the I:E ratio from 1:1.9 to 2:1 and then to 2.6 or 4:1 was applied when PEEP failed to raise the PaO2(More)
To determine whether normothermic cardiopulmonary bypass (CPB) and cardioplegia preserve myocardial function, reduce inotropic requirements, and reduce markers of myocardial ischemia following coronary artery bypass graft surgery (CABG). We retrospectively reviewed the charts of 171 consecutive patients undergoing elective CABG by a single surgeon from(More)
A 49-year-old woman, 154 cm in height and 58 kg in weight, underwent a radical hystrectomy for uterine cancer. Five days later, she suddenly complained of a severe chest pain, and subsequentry fell into cardiac arrest. Cardiopulmonary resuscitation (CPR), including endotracheal intubation, closed-chest cardiac massage, and an intravenous injection of(More)
The purpose of this study was to assess perioperative changes in psychological features of patients receiving anesthesia and operation. Anxiety level and desire for obtaining information were evaluated in 37 patients using the Amsterdam preoperative anxiety and information scale (APAIS) at three points: before and after the preanesthetic examination, and 3(More)
