Augmentation of the neuromuscular blocking effects of cisatracurium during desflurane, sevoflurane, isoflurane or total i.v. anaesthesia.
We have evaluated the enhancement of cisatracurium-induced neuromuscular block by potent inhalation anaesthetic agents, by constructing dose-effect curves for cisatracurium in 84 patients during anaesthesia with 1.5 MAC (70% nitrous oxide) desflurane, sevoflurane, isoflurane or total i.v. anaesthesia (TIVA). Acceleromyography (TOF-Guard) and train-of-four (TOF) stimulation of the ulnar nerve we...
متن کاملInfluence of 0.1 minimum alveolar concentration of sevoflurane, desflurane and isoflurane on dynamic ventilatory response to hypercapnia in humans.
To assess the effects and site of action of a sub-anaesthetic concentration of isoflurane, desflurane and sevoflurane (0.1 minimum alveolar concentration (MAC)) on respiratory control, we measured the ventilatory response to square wave changes in PE1CO2 against a background of normoxia. Using the computer steered "end-tidal forcing system", 2 min of steady state ventilation were followed by a ...
متن کاملRelationships between Bispectral Index, Implicit Memory, Dream Recall and Minimum Alveolar Concentration in Blended Anaesthesia
The decreased responsiveness to stimulation defines the depth of anaesthesia which is a balance between effects of anaesthetic drugs and surgical stimulations. Awareness is a rare occurrence with an incidence of 0,1-0,2 %1, defined as postoperative recall of events occurring during general anaesthesia. This memory can be traumatic and may result in developing a chronic posttraumatic stress diso...
متن کاملEffect of nitrous oxide on bispectral index values at equi-minimum alveolar concentrations of sevoflurane and desflurane
BACKGROUND AND AIMS Bispectral index (BIS) values may be anaesthetic agent-specific, depending on their ability to suppress the electroencephalogram (EEG) signals. We carried out a prospective, randomised clinical trial to study the effect of nitrous oxide (N2O) on the BIS values at an equi-minimum alveolar concentration (MAC) of sevoflurane and desflurane. METHODS Sixty adult patients underg...
متن کاملRecovery after anaesthesia for pulmonary surgery: desflurane, sevoflurane and isoflurane.
We have studied maintenance and recovery profiles after general anaesthesia with sevoflurane, desflurane and isoflurane in 100 patients undergoing pulmonary surgery. End-tidal concentrations of anaesthetic required to maintain mean arterial pressure and heart rate within 20% of baseline values were 1.4 +/- 0.6% for sevoflurane, 3.4 +/- 0.9% for desflurane and 0.7 +/- 0.3% for isoflurane. The th...
