Comparison of a prototype esophageal oximetry probe with two conventional digital pulse oximetry monitors in aortocoronary bypass patients
Autor: R C, Prielipp, P E, Scuderi, M H, Hines, J L, Atlee, J F, Butterworth
Publikováno v: Journal of clinical monitoring and computing. 16(3)
Pulse oximetry (SpO2) is the non-invasive standard for monitoring arterial oxygen saturation in patients undergoing anesthesia, but is subject to external interference by motion artifact, peripheral vasoconstriction, and low cardiac output. We hypoth

Dobutamine antagonizes epinephrine's biochemical and cardiotonic effects: results of an in vitro model using human lymphocytes and a clinical study in patients recovering from cardiac surgery
Autor: R C, Prielipp, D A, MacGregor, R L, Royster, N D, Kon, M H, Hines, J F, Butterworth
Publikováno v: Anesthesiology. 89(1)
Patients may receive more than one positive inotropic drug to improve myocardial function and cardiac output, with the assumption that the effects of two drugs are additive. The authors hypothesized that combinations of dobutamine and epinephrine wou

Treatment of hypotension after hyperbaric tetracaine spinal anesthesia. A randomized, double-blind, cross-over comparison of phenylephrine and epinephrine
Autor: R F, Brooker, J F, Butterworth, D W, Kitzman, J M, Berman, H I, Kashtan, A C, McKinley
Publikováno v: Anesthesiology. 86(4)
Despite many advantages, spinal anesthesia often is followed by undesirable decreases in blood pressure, for which the ideal treatment remains controversial. Because spinal anesthesia-induced sympathectomy and management with a pure alpha-adrenergic

Effect of pH and lidocaine on beta-adrenergic receptor binding. Interaction during resuscitation?
Autor: V E, Modest, J F, Butterworth
Publikováno v: Chest. 108(5)
Epinephrine and other beta-adrenergic receptor (beta AR) agonists are often administered during cardiopulmonary resuscitation, a time when acid-base abnormalities and arrhythmias also commonly occur. We tested whether beta 2AR binding is influenced b

Calcium entry attenuates adenylyl cyclase activity. A possible mechanism for calcium-induced catecholamine resistance
Autor: W B, Abernethy, J F, Butterworth, R C, Prielipp, J P, Leith, G P, Zaloga
Publikováno v: Chest. 107(5)
In experimental animals, coadministration of calcium (Ca) salts with beta-adrenergic receptor agonists reduces the increased blood pressure and cyclic AMP (cAMP) produced by beta-adrenergic receptor agonists alone. In patients, coadministration of th

Pharmacologic cardiovascular support
Autor: G P, Zaloga, R C, Prielipp, J F, Butterworth, R L, Royster
Publikováno v: Critical care clinics. 9(2)
The availability of newer and better inotropic agents has led to their widespread application in critically ill medical and surgical patients. Although the elective use of inotropic drugs has been associated with adverse outcomes in patients with car

The alpha 2-adrenergic agonists clonidine and guanfacine produce tonic and phasic block of conduction in rat sciatic nerve fibers
Autor: J F, Butterworth, G R, Strichartz
Publikováno v: Anesthesia and analgesia. 76(2)
To determine whether alpha 2-adrenergic agonists inhibit impulse conduction, clonidine and guanfacine were applied to rat sciatic nerve fibers studied in vitro. Clonidine and guanfacine produced concentration-dependent, tonic inhibition of compound a

Do antiarrhythmic doses of magnesium potentiate vecuronium?
Autor: P, Frawley, J F, Butterworth
Publikováno v: Nurse anesthesia. 3(1)
The purpose of this study was to investigate whether magnesium sulfate (MgSO4) at a dose commonly used to treat arrhythmias potentiates vecuronium. After Institutional Review Board approval, 20 randomly assigned, consenting patients received a bolus

Low concentrations of procaine and diethylaminoethanol reduce the excitability but not the action potential amplitude of hippocampal pyramidal cells
Autor: J F, Butterworth, L R, Cole
Publikováno v: Anesthesia and analgesia. 71(4)
To determine whether concentrations of diethylaminoethanol (DEAE) and procaine below those that reduce the amplitude of action potentials might alter the excitability of brain cells, a single microelectrode intracellular recording technique was used
