ve To investigate the time course of potentiation of rocuronium produced by 1MAC of desflurane or isoflurane. Methods Twenty-four ASA I-II patients aged 18-60 years undergoing elective abdominal operation under general anesthesia were studied. Patients with neuromuscular, liver or kidney disease and those receiving any drug which may affect neuromuscular transmission were excluded. Premedication consisted of intramuscular phenobarbital 0.1 and atropine 0.5mg 30min before operation. Anesthesia was induced with midazolam 0.1-0.2 mg?kg-1, fentanyl 6?g.kg-1 and etomidate 0.3mg?kg-1 .Tracheal intubation was facilitated with rocuronium 0.6mg?kg-1 iv. The degree of neuromuscular block was monitored by measuring muscle response to TOF using accelerography (Biometer) . For maintenance of anesthesia the patients were randomly assigned to receive either propofol + fentanyl (control group) or 1 MAC of desflurane + propofol + fentanyl (desflurane group) or 1 MAC of isoflurane + propofol + fentanyl(isoflurane group). Rocuronium was continuously infused during operation to maintain T1 at 5 % of the control and the infusion rate was recorded every 15 min. Results There were no significant differences among the three groups with respect to sex, age, body weight and duration of anesthesia. In Des and Iso groups the infusion rate of rocuronium was reduced in an exponential manner and maximal potentiation occurred at 90 min of isoflurane or desflurane inhalation. The maximal reduction in infusion rate was 42.7 % in Des group and 37.6% in Iso group. There was no significant difference between the two groups.Conclusions Desflurane and isoflurane can potentiate the muscle relaxation produced by rocuronium in a similar degree and the potentiation is time dependent.

Objective To investigate the change in neuromuscular blocking effect of rocuronium induced by liver dysfunction. Methods Forty patients undergoing elective liver and biliary tract operation under general anesthesia were divided into 2 groups : (A) control group included 20 patients with normal liver function and (B) liver dysfunction group included 20 patients with obstructive jaundice. The premedication consisted of phenobarbital 0.lg and atropine 0.5 mg. Anesthesia was induced with midazolam 0.1 mg?kg-1,fentanyl 6?g?kg-1 and etomidate 0.3 mg?kg-1.The neuromuscular function was monitored by TOF stimulation of the ulnar nerve using accelerograph (Biometer).Rocuronium 0.6 mg?kg-1 was administered iv via the vein in the upper arm.The patients were intubated when T1 was 95% depressed and mechanically ventilated.PETCO2 was maintained at 35-40 mm Hg.The onset time (from the end of injection to T1=0),clinical duration of action (from the end of injection to 25% recovery of T1) and recovery index (T1 from 25% to 95% ) were recorded.MAP, HR and SpO2 were recorded before and at 5 and 10 min after rocuronium injection.Results The demographic data including sex, age and weight were comparable between the two groups. The onset time was (63?19) s in group A and (70?21) s in group B.The difference was not statistically significant. The clinical duration of action was (41?16) min in group A and (67?29) min in group B (P0.05).Conclusion Liver dysfunction induced by obstructive jaundice prolongs the clinical duration of action,but does not significantly affect the onset time of and recovery from rocuronium.

Objective To investigate the effect of desflurane on neuromuscular blockade of rocuronium Methods Thirty adult patients ,scheduled for selective surgery under general anesthesia, were randomly allocated to receiving intravenous propofol 4mg?mg -1 (group I,n=10),inhalation of 1MAC(6%) desflurane lasting 15 min (group Ⅱ,n=10) or 45 min(group Ⅲ,n=10) to maintain anesthesia,respectively Rocuronium 0 6 mg?kg -1 was given intravenously in group I following stable anesthesia , in group Ⅱ or group Ⅲ with the stable end tidal concentration of desflurane at 1MAC for 15 min or 45 min,respectively The onset time and degree of neuromuscular blockade were monitored with train of four(TOF) technique.Results The onset times of T 1 and TOF in group Ⅲ(1 3 and 0 8 min) were shorter than in group I(2 2 and 1 5 min)(P
