To evaluate the accuracy of a new non-invasive method (Vasotrac) to measure blood pressure (BP) with accompanying arterial wave-form and pulse-rate display when compared with BP and waveform measured invasively. ⋯ The Vasotrac system displayed an arterial waveform which was similar to that obtained directly and measured BP and pulse rate accurately. It should be a convenient device to measure BP continually in a non-invasive fashion.

Randomized Controlled Trial Comparative Study Clinical Trial
Ropivacaine vs bupivacaine in major surgery in infants.
To assess and compare the onset time and duration of neuroblockade obtained after ropivacaine or bupivacaine in infants undergoing major abdominal surgery. We also evaluated the efficacy and safety of employing ropivacaine instead of bupivacaine to provide operative anesthesia and postoperative analgesia. ⋯ In infants undergoing major abdominal surgery under combined epidural/light general anesthesia, ropivacaine 0.2% produces sensory and motor blockade similar in onset, duration of action and efficacy to that obtained from an equal volume, 0.7 ml x kg(-1), of bupivacaine 0.25%.

Randomized Controlled Trial Clinical Trial
Reduced efficacy of simulated epidural test doses in sevoflurane-anesthetized adults.
To determine the hemodynamic responses to, and the efficacy of epinephrine-containing epidural test doses, during sevoflurane anesthesia, based on the conventional heart rate (HR) increase > or = 20 beats x min(-1), the modified HR increase if > or = 10 beats x min(-1), and the systolic blood pressure (SBP) increase 15 mmHg criteria. ⋯ During stable sevoflurane anesthesia, peak HR increase > or = 10 beats x min(-1) should be regarded as a positive response with end-tidal sevoflurane concentration < or = 1%, and peak SBP increase > or = 15 mmHg is applicable at sevoflurane concentrations between 0.5 and 2%.
