摘要:
Hemodynamic effects of propranolol during coronary artery surgery were investigated in 26 patients who chronically took propranolol and who received a standardized morphine/diazepam/pancuronium/halothane anesthetic. Effects were shown by correlating logarithm of the plasma propranolol concentrationsversuspercentage change in hemodynamics following stressful events (induction, intubation, skin incision, sternotomy, and sternal retraction). Log propranolol and hemodynamics following cardiopul-monary bypass also were correlated. A broad range of propranolol levels were observed. Levels (range and mean · SD) were preinduction 0–96 (25.6 · 21.6) ng/ml; preincision 0–86 (27.2 · 24.4) ng/ml; and sternal retraction 0–92 (28.2 · 25.4) ng/ml. The range of hemodynamic responses to stressful events also was broad. Representative changes between preincision control and sternotomy were (range and mean · SD): HR −8–30 (7 · 10) beats/min; PCWP 1–21 (8.5 · 4.6) mmHg; CI −0.2–1.1 (−0.2 · 0.7) 1 · min−1· m−2, and SVR −244–1,288 (310 · 388) dyn · s · cm−5. By the time of sternal retraction, CI had declined from preincision values in 14 patients. Linear regression analysis demonstrated an inverse correlation between log propranolol and magnitude of HR, MAP, PCWP, and CI response to stressful stimulation. A direct but statistically weaker correlation with SVR also was seen. Significant correlations between log propranololversushemodynamic response to anesthetic induction andversuspostcardiopulmonary bypass hemodynamics were not observed. The authors conclude that propranolol, in proportion to the log plasma level, attenuated stress-induced changes in HR and to a lesser degree changes in MAP, PCWP, and CI and that at higher levels this effect was achieved with some decline in CI and increase in SVR.

摘要:
Voltage and current output characteristics were measured on six commercially available peripheral nerve stimulator devices. The results are evaluated as possible sources of variability in peripheral nerve stimulator function and neuromuscular blockade assessment. The authors found significant differences in output voltage waveform and in maximum current into a 470 ohm load (21.4 to 128 mA.). Output current decreased from 25 to 88% in the different devices, with a load impedance increase from 470 to 10,000 ohms. Due to the variability in peripheral nerve stimulation units and the decrease in current output at higher load impedance, less than supramaximal stimulation is possible with erroneous interpretation of neuromuscular blockade.
