Background: Purpose of the study was to evaluate the efficacy of Atracurium as adjuvant with tramadol or Ketorolac in reducing the dose of lignocaine used for intravenous regional anesthesia thereby decreasing the chances of systemic toxicity of lignocaine. Patients and Methods: The study was done in Department of Anaesthesia, Santhiram Medical College and General Hospital, Nandyal. 75 adult pa...

BACKGROUND The purpose of this study was to validate a new level of consciousness monitor derived from the EEG, called the index of consciousness (IoC), by comparing it with the bispectral index (BIS) and the cerebral state index (CSI) during general anaesthesia for cardiac surgery using sevoflurane, remifentanil, and atracurium. METHODS After ethical committee approval and written patient co...

We have determined neuromuscular blocking effects of atracurium and vecuronium at normal, high and low plasma concentrations of ionized calcium ( [Ca2+] ) in the cat. Twitch responses were measured bilaterally in the anterior tibialis muscles, using intact central innervation in one preparation. Plateaus of high and low [Ca2+] were created by infusions of calcium chloride and citrate, respectiv...
