TL;DR: The effects of shivering on hemodynamics and systemic oxygenation, as well as the effectiveness of therapeutic interventions in decreasing shivering and increasing mixed venous oxygen saturation, were studied.

TL;DR: The authors conclude that such capability increases sensitivity to small ST segment changes, and heightened awareness and prompt remedial action reduced the incidence of ischemia during CABG to 6% during the final 2 years of the study.

TL;DR: A case is reported of a patient, following aortocoronary bypass surgery, who was in severe biventricular failure, unresponsive to treatment with high doses of norepinephrine and phentolamine, whose addition to the patient's treatment resulted in marked improvement in his clinical condition, cardiac index, and mixed venous oxygen saturation.

TL;DR: Intrathecal morphine at the dose of 0.02 mg/kg does not offer any clear benefit to patients anesthetized with fentanyl, 40 microg/kg, for coronary artery bypass surgery, and comparable and significant reductions of peak expiratory flow rates (PEFR), forced vital capacity (FVC), and forced expiratories volume (FEV1) occurred in both groups postextubation when compared with preoperative values.

TL;DR: Preoperative normal regional myocardial function was not affected by coronary revascularization, and dysfunctioning myocardium frequently improved immediately after revascularized, as well as in the intensive care unit.

TL;DR: The case presented demonstrates prolonged ventilation in both the operating room and intensive care unit via the ETC after unsuccessful attempts to intubate the trachea with a conventional endotracheal tube.

TL;DR: The first intraoperative experience with this new enhancement to two-dimensional transesophageal echocardiography (TEE) showed that this relatively noninvasive technique is a safe method allowing constant monitoring of cardiac and pulmonary blood flow velocities.

TL;DR: FC-43 pretreatment altered the sequelae of CAE in pentobarbital-anesthetized, oxygen-ventilated dogs, revealing a significantly lower systemic mean arterial pressure (MAP), LVEDP, left ventricular stroke work index (LVSWI), and right ventricular Stroke Work index (RVSWI) in the group receiving the FC-43 prior to receiving CAE.

TL;DR: The results suggest that the degree of distention of the atria regulates the secretion of atrial natriuretic peptide into the circulation in patients anesthetized with fentanyl.

TL;DR: Modest volume loading can be used to maintain transmural filling pressures (and cardiac output) when PEEP is used after coronary artery bypass surgery.

TL;DR: The results suggest that a modest dose of fentanyl followed by etomidate may be an attractive alternative to high doses of fentanyl in patients with limited cardiovascular reserve, especially when prolonged postoperative respiratory depression secondary to high dose of an opioid is undesirable.

TL;DR: Investigation of the effect of ATP on aortic XC in a canine model showed the drug to produce a smooth, predictable, and rapid reduction in left ventricular preload and afterload with minimal changes in distal organ perfusion, some improvement in measured cardiac performance, and a large increase in myocardial blood flow.

TL;DR: It is determined that right ventricular failure remains the leading cause of inability to terminate cardiopulmonary bypass in this patient population, and in surveyed institutions, cardiac transplantation expends more physician as well as hospital resources per patient than coronary artery bypass surgery.

TL;DR: The Janssen Annual Lecture on “adverse hemodynamic responses to protamine” was given by E. Lowenstein of Harvard Medical School, Boston, providing an oversight of current research in the field of cardiovascular anesthesia.

TL;DR: In group N there was a significant correlation (r = 0.65; P less than .05) between the increases in MVO2 and LV percentage area reduction, an estimate of myocardial function, and the use of nifedipine was associated with increases inMVO2, myocardian norepinephrine release, and inotropy.

TL;DR: A hindlimb preparation of 19 male rats was used to determine the responses to norepinephrine at different levels of hemodilution at a constant flow, at increased flow and maintained pressure, and after reversal of heModilution.

TL;DR: The data suggest that at MAC fractions up to 0.6, ENF is less cardiodepressant than ISO or HAL, but that ENF has a tendency to be more depressant than HAL or ISO at concentrations higher than 1.0 MAC.

TL;DR: A report of a case of perforation of a pulmonary artery in an anticoagulated cardiac surgical patient before coming off cardiopulmonary bypass, which necessitated an emergency right middle lobectomy is reported.

TL;DR: Heparin responsiveness decreased significantly with high platelet counts and advanced age, but was unaffected by the initial hematocrit, ACT, partial thromboplastin time, or preoperative heparin therapy.

TL;DR: It is concluded that the relative effects on the systemic and pulmonary circulations differ for the four drugs; rational choice of a vasopressor will depend upon the hemodynamic situation and the desired effect.
