BACKGROUND: Neuromuscular blockade (NMB) is a frequent component of anesthetic techniques used during surgery in which monitoring of the nervous system is desirable. Because NMB should affect the evoked muscle response to transcranial magnetic stimulation (tcMMEP), their relationship in a primate model was characterized. METHODS: Transcranial magnetic stimulation was characterized ...
Belani K - - 1993
BACKGROUND: Sufficient hypothermia during anesthesia provokes thermoregulatory responses, but the clinical significance of these responses remains unknown. Nonshivering thermogenesis does not increase metabolic heat production in anesthetized adults. Vasoconstriction reduces cutaneous heat loss, but the initial decrease appears insufficient to cause a thermal steady state (heat production equaling heat loss). ...
Furuya K - - 1993
We studied the responses of plasma epinephrine, norepinephrine, adrenocorticotropic hormone (ACTH), cortisol, and antidiuretic hormone (ADH) during and immediately after sevoflurane-nitrous oxide anaesthesia supplemented with vecuronium in seven elderly patients (mean 76.6 +/- 1.7 SEM) who underwent major intra-abdominal surgery. The plasma concentrations of norepinephrine, ACTH, cortisol, and ADH increased ...
