We studied the cardiovascular effects of esmolol, a newly synthesized beta-adrenocepter antagonist, in anesthetized humans. Forty patients (four groups of 10 each) with ischemic heart disease and normal ventricular function were anesthetized with diazepam, pancuronium, and N2O in O2. Esmolol was given by continuous infusion in cumulative doses of 1100(More)
The design and implementation of a computer-assisted continuous infusion (CACI) system to rapidly attain and maintain a constant plasma fentanyl concentration (PFC), as well as a CACI system that allowed the anesthesiologist to change the plasma level of fentanyl during cardiac anesthesia, were developed. In 30 patients (three groups of 10 patients each)(More)
We reviewed the perioperative courses of 110 children of members of the Jehovah's Witness faith who underwent 112 operations for complete repair of congenital heart disease with cardiopulmonary bypass. Operations were performed over a 20 year period, ending June, 1983. The children ranged in age from 6 months to 12 years and weighed 5.2 to 42.3 kg.(More)
We evaluated risk of heart block after cardiopulmonary by-pass (CPB) in patients with normal conduction undergoing coronary artery bypass grafting who chronically received calcium-entry blockers, beta-blockers, or combined therapy. Before CPB, calcium-entry blockers alone produced an increase in P-R intervals but no change in heart rate; calcium-entry(More)
BACKGROUND Our objective was to evaluate our results after the implementation of lean (the elimination of wasteful parts of a process). METHODS After meetings with our anesthesiologists, we standardized our "in the operating room-to-skin incision protocols" before pulmonary lobectomy. Patients were divided into consecutive cohorts of 300 lobectomy(More)
