Abstract:
Objective To evaluate the effects of long?term glucocorticoid administration on cisatra?curium?induced neuromuscular blockade in the patients undergoing laparoscopic operation. Methods Six?ty?four patients of both sexes, aged 40-64 yr, with body mass index of 18-22 kg∕m2 , of American Society of Anesthesiologists physical status Ⅱ or Ⅲ, scheduled for elective laparoscopic operation under general anesthesia, were assigned into 4 groups ( n=16 each) according to whether or not glucocorticoid was used for a long?term period: control ( non?hormone and non?laparoscopic operation ) group ( group C ) , hor?mone + laparoscopic operation group ( group HL ) , non?hormone + laparoscopic operation group ( group NHL) and hormone +non?laparoscopic operation group ( group HNL) . Midazolam 0.03 mg∕kg was injected intravenously, 8% sevoflurane was inhaled by mask, and the concentration of sevoflurane was decreased by 2% every 30 s until the concentration of 4% was reached. After loss of eyelash reflex, remifentanil 2μg∕kg was injected intravenously over 1 min, and 30 s later sevoflurane inhalation was stopped. The patients were tracheally intubated and mechanically ventilated. Anesthesia was maintained with propofol and remifentanil given by target?controlled infusion. Neuromuscular blockade was monitored with accelerograph TOF?watch
SX. At 20 min of pneumoperitoneum in NHL and HL groups or 20 min after intubation in C and HNL groups, cisatracurium 0. 15 mg∕kg was injected intravenously. The onset time, maximal degree of N?M block, clinical duration and recovery index of cisatracurium were recorded. Results Compared with group C, the onset time was significantly prolonged, the maximal degree of N?M block was decreased, the clini?cal duration was shortened, and the recovery index was decreased in HL and HNL groups ( P<0.05) , and the clinical duration was significantly prolonged, the recovery index was increased ( P<0.05) , and no sig?nificant change was found in the onset time in group NHL ( P>0.05) . Compared with group HNL, the clin?ical duration was significantly prolonged, the recovery index was increased (P<0.05), and no significant change was found in the onset time in group HL ( P>0.05) , and the onset time was significantly shortened, the clinical duration was prolonged, and the recovery index was increased in group NHL ( P<0.05) . Com?pared with group NHL, the onset time was significantly prolonged, the maximal degree of N?M block was decreased, the clinical duration was shortened, and the recovery index was decreased in group HL ( P<0.05) . Conclusion Long?term glucocorticoid administration can weaken cisatracurium?induced neuromus?cular blockade in the patients undergoing laparoscopic operation.
