OBJECTIVE:To compare therapeutic efficacy and safety of desflurane and sevoflurane for anesthesia of elderly pa-tients. METHODS:A randomized,parallel-controlled method was used,120 elderly patients undergoing anesthesia were random-ized into trial group and control group,with 60 cases in each group. Based on routine medication and disposal,control group was additionally given sevoflurane for anesthesia,and trial group given desflurane for anesthesia. The blood pressure and heart rate were recorded before anesthesia,2 min and 10 min after intubation,2 min and 30 min after the start of the operation;the extubation time,eye opening time,consciousness recovery time and postoperative complications were also recorded. RESULTS:10 min after intubation,the heart rate of trial group was significantly faster then that of control group,with statistical significance(P<0.05);the blood pressure and heart rate of 2 groups had no statistically significant difference between 2 groups at other time points(P>0.05). The extubation time and consciousness recovery time of trial group were significantly shorter than those of control group, with statistical significance(P<0.05). The postoperative complications mainly were hypopiesia,hypertension,bronchospasm,nau-sea and vomiting,and dysphoria;the incidence of postoperative complications in trial group and control group were 25.0% and 40.0%,with statistical significance (P<0.05). CONCLUSIONS:Desflurane is effective with less postoperative complications for the anesthesia of elderly patients.

OBJECTIVE:To observe the efficacy and safety of low-dose ropivacaine combined with sufentanil in the upper limb anesthesia. METHODS:100 patients with upper limb anesthesia were randomly divided into control group and test group. Control group was intravenously injected 20 ml 0.5% ropivacaine;test group was intravenously injected 20 ml 0.375% ropivacaine +10 μg sufentanil. The anesthesia effect,disappearance time of pain,duration of analgesia,and pain visual analogue (VAS) score before anesthesia(T0),5 min(T1),15 min(T2)and 30 min(T3)after anesthetic block,and 4 h(T4)and 8 h(T5)after surgery,and in-cidence of adverse reactions in 2 groups were observed. RESULTS:VAS scores at T1-T5 in test group and T2-T4 in control group were significantly lower than T0,test group was lower than control group at T1,T2 and T5,the differences were statistically signifi-cant(P<0.05). The total effective rate of anesthesia in test group was significantly higher than control group,disappearance time of pain was significantly shorter than control group,duration of analgesia was significantly longer than control group,incidence of adverse reactions was significantly lower than control group,the differences were statistically significant(P<0.05). CONCLU-SIONS:Both the efficacy and safety of low-dose ropivacaine combined with sufentanil in the upper limb anesthesia are good.

Objective To investigate the influence of high-fat diet in the intestinal flora,fecal weight and its water content in rats, and to clarify the effect and significance of high-fat diet in the occurrence of obesity forming. Methods Twenty Sprague-Dawley (SD)rats were randomly divided into normal diet (ND)group and high-fat diet (HF)group (n=10).The rats in ND group were fed with normal diet,and the rats in HF group were fed with diet rich in oil and fat.The fresh feces were collected separately on days 1,15,30,and 49 for analysis of weight, water content,and intestinal flora.Results On the 49th day,the wet weight and water content of feces of the rats in ND group were (6.61 ± 0.17)g and (37.07 ± 3.04)%,respectively,while those in HF group were (4.46±0.30)g and (18.04±2.23)% (P<0.05).Compared with ND group ,the fecal pellets in HF group were increased obviously from the 7th day (P<0.05).There were obvious changes in intestinal microbial populations of HF group. The counts of enterococci, bifidobacteria, Lactobacillus, Bacteroides bacteria were significantly decreased on the day 49, but the count of Escherichia coli was increased significantly (P < 0.05 ). Conclusion High-fat diet can result in decrease for weight,water content,and pellets of feces;it can change the structure of intestinal flora. As result, there is a possibility that all of changes above can promote obesity in the future.
