RESUMO

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 ( P0.05) . Compared with group HNL, the clin?ical duration was significantly prolonged, the recovery index was increased (P0.05) , 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.

RESUMO

Objective To investigate the effects of long-term glucocorticoid administration on neuromuscular block of cisatracurium in elderly patients undergoing general anesthesia. Methods Forty ASA Ⅱ or Ⅲ patients,aged≥65 yr,with BMI of 18-24 kg/m2 ,scheduled for elec-tive operation were studied.According to the history of using or not long-term glucocorticoid,patients were assigned into two groups (n = 20 each):control group(group C),glucocorticoid group(group J).Midazolam 0.03 mg/kg was injected,mask inhalation of 8% sevoflurane and flow rate of oxygen 8L,every 30 s decline 2%,until the 4%.After the disappearance of eyelash reflex,cisatracurium 0.1 5 mg/kg was injected intravenously.After 1 min intravenous injection of remifentanil 2 g/kg and 30 s after stop of sevoflurane inhalation anesthesia, endotracheal intubation for mechanical ventilation,target controlled infusion of propofol and remifentanil anesthesia,using TOF-Watch SX acceleromyography monitoring of muscle relaxation,and onset time,clinical duration and recovery in-dex(for T1 to return from 25% to 75% of the control twitch)were recorded.Results Compared with group C,the onset time was significantly prolonged,clinical duration and recovery index were short-ened in group J (P <0.05 ).Conclusion Long-term glucocorticoid admininstration could reduce the neuromuscular blocking effect of cisatracurium in elderly patients.

RESUMO

Objective To evaluate the effect of domestic wire-reinforced epidural catheter on the occurrence of adverse events during epidural block.Methods Three hundred ASA Ⅰ or Ⅱ patients of both sexes,aged 18-64 yr,weighing 41-78 kg,scheduled for elective operations under combined spinal-epidural anesthesia,were randomly divided into 3 groups (n =100 each):polyvinyl chloride epidural catheter group (group A),imported wire-reinforced epidural catheter group (group B) and domestic wire-reinforced epidural catheter group (group C).Combined spinal-epidural anesthesia was performed routinely.The corresponding epidural catheter was inserted in each group.The catheterization without difficulty,paresthesia during catheterization,the number of patients in whom blood or cerebrospinal fluid was withdrawn from the epidural catheter,intravascular catheter insertion,injection obstruction,easiness during removal of the catheter,bleeding after removal,postoperative paresthesia and epidural hematoma within 1 week after operation were recorded.Results Compared with A group,the incidences of paresthesia during catheterization,the number of patients in whom blood or cerebrospinal fluid was withdrawn from the epidural catheter,injection obstruction and postoperative paresthesia were significantly decreased (P < 0.05),and no significant change was found in the other parameters in B and C groups (P > 0.05).There was no significant difference in all the parameters between B group and C group (P > 0.05).Conclusion Domestic wire-reinforced epidural catheter can decrease the occurrence of catheterization-induced damage to the nerve and blood vessels and the efficacy is comparable with that of imported wire-reinforced epidural catheter.

RESUMO

Objective To investigate the effects of Sangju Qingjie Decoction on the ventilator-induced lung injury in rats.Methods Thirty-six healthy male SD rats of both sexes,weighing 300-350 g,were randomly divided into 3 groups(n =12 each):control group(group C); mechanical ventilation group(group V)and Sangju Qingjie Decoction group(group SJ).The animals were anesthetized with intraperitoneal 3% urethane 1.4 g/kg and tracheostomized.The femoral artery and vein were cannulated for blood sampling and drug administration.The animals were mechanically ventilated for 2.5 h(VT =40 ml/kg,RR 40 bpm,I:E =1:1,FiO2 21%).Ingroup SJ,Sangju Qingjie Decoction 300 g was injected into the stomach through a gastric tube once a day for 10 consecutive days,and mechanical ventilation was performed 2 h after the last injection.While in groups V and C,the equal volume of normal saline was given instead of Sangju Qingjie Decoction.Arterial blood samples were collected before ventilation,at the end of ventilation,and at 30 min after ventilation(T0-2)for blood gas analysis.Respiratory index(RI)and oxygenation index(OI)were calculated.The animals were then sacrificed and the lungs were removed for microscopic examination and determination of the content of TNF-α,IL-6 and IL-10 and W/D lung weight ratio.Results Compared with group C,RI at T1,2,the content of TNF-o,IL-6 and IL-10 and W/D ratio were significantly increased,and OI was significantly decreased at T1.2 in groups V and SJ(P < 0.05).Compared with group V,RI at T1,2,the content of TNF-α and IL-6 and W/D ratio were significantly decreased,and OI at T1,2 and the content of IL-10 were significantly increased in group SJ(P < 0.05).The pathological damage was attenuated in group SJ compared with group V.Conclusion Sangju Qingjie Decoction can attenuate the ventilator-induced lung injury through inhibition of inflammatory response in rats.
