Objective To compare the effects of sevoflurane and propofol anesthesia on endothelial glycocalyx degradation in the patients undergoing abdominal surgery.Methods Sixty American Society of Anesthesiologists physical status Ⅰ or Ⅱ patients of both sexes,aged 25-75 yr,weigbing 45-80 kg,scheduled for elective open colon or rectal surgery,were divided into 2 groups (n =30 each) using a random number table method:sevoflurane anesthesia group (group S) and propofol anesthesia group (group P).In group S,1.5%-2.5% sevoflurane was inhaled for maintenance of anesthesia.In group P,propofol was intravenously infused at 50-150 μg · kg-1 · m-1 to maintain the bispectral index value at 40-60.The concentrations of heparan sulfate (HS),syndecan-1 and vascular cell adhesion molecule-1 (VCAM-1) in serum were determined after tracheal intubation (T0),at 1 h after skin incision (T1),at 2 h after skin incision (T2),at the end of operation (T3) and at 24 h after operation (T4).Blood gas analysis and blood biochemical test were performed at T0 and T4,and strong ion gap (SIG) was calculated.Results Compared with the baseline at T0,the concentrations of serum HS at T2-4 and syndecan-1 at T3-4 and SIG at T4 were significantly increased,and the concentrations of serum ALB at T4 were decreased in S and P groups (P<0.05).Compared with group P,the concentrations of serum HS at T3,4 and syndecan-1 at T4 and SIG at T4 were significantly decreased,the concentrations of serum ALB at T4 were increased (P<0.05),and no significant change was found in the serum concentrations of VACM-1 and lactate in group S (P>0.05).Conclusion Compared with propofol anesthesia,sevoflurane anesthesia is more helpful in decreasing endothelial glycocalyx degradation and in reducing vascular endothelial damage in the patients undergoing abdominal surgery.

Objective To observe the effect of different doses of butorphanol and sufentanil repeatedly epidural injected on the neurobehavior function in bone cancer model rats.Methods A PE-530 catheter was inserted into the epidural space of all male Sprague-Dawley rats(not mated,weighting 150-180 g) at L1-2 level.Three days after operation,64 rats without any motor dysfunction were randomly divided into eight groups (n=8):sham operated group (group C),normal saline with bone cancer pain group (group N),butorphanol groups(group B 1,B2,B3)and sufentanil groups (group S1,S2,S3).Bone cancer pain model was constructed in group N,B and S when rats in group C were sham operated.Rats in group C and N were epidurally injected NS 30μl each,and rats in group B1,B2 and B3 were respectively epidurally injected butorphanol 25,50,100 μg (all diluted to 30 μl with NS),when rats in group S1,S2 and S3 were respectively cpidurally injected sufentanil 1,2,4 μg (all diluted to 30 μl with NS) on time per day for 10-14 days after modeling.The neurobehavior paw withdrawal threshold (MWT) of the left hind claw was recorded to observe the changes in pain behavior.The neurobehavior function of rats were recorded by BBB (BASSO,BEATTIE and BRESNAHAN) score and the inclined plane test.Results Compared with group C((67.65±9.29) g),the MWT of the model groups obviously decreased before the first time of injection (N (15.23± 2.46) g,B 1 (16.14±2.28) g,B2(15.42±3.22) g,B3(14.35±2.32) g,S1 (15.37±2.11)g,S2(15.22±2.93) g,S3(16.25± 2.36) g) (all P<0.05)).Compared with group N((16.13±2.37) g),the MWT of group B2,B3 and S3 increased obviously after the first time of injection ((35.12±5.16) g,(35.63± 1.53) g and (34.24±5.93) g) (P< 0.05).At the first day of injection,there was no significant difference in the BBB scores and the inclined plane test between the model groups (P>0.05).At 6 h after the forth injection the inclined plane test and the BBB scores of group B3 were obviously decreased compared with group N ((34.72 ± 4.56) ° and (10.64 ± 1.82) points to (43.15±4.67)° and (14.05±1.78) points (P<0.05)).Conclusion The results provide evidence that repeatedly epidural injection of butorphanol 50 μg or 100 μg or sufentanil 4 μg can reduce the pain of the rats with bone cancer pain.But repeated epidural injection of butorphanol 100 μg can injure the neurological function.
