ObjectiveTo observe the difference in analgesia effects of ropivacaine with fentanyl used intraarticularly after the single knee arthroscopy procedure.Methods40 patients performed knee arthroscopy under combined spinal-epidural anaesthesia( CSEA),were randomly divided into 4 groups (n =10),at the end of operation 10mlof different drug at the group F,R,FR and N(fentanyl 10μg,0.5％ ropivacaine,fentanyl 10μg +0.5％ ropivacaine,normal saline)were injected intra-articularly.The antalgic effects of four groups based on standard of VAS were observed at the 2,4,8,12 and 24h after operation.ResultsThe 2h postoperative VAS scores were lower in four groups,the differences in four groups were not significant.The 4,8,12,24h postoperative VAS scores of F,R and FR group were much lower than that of N group ( all P ＜ 0.05 ).Moreover,VAS scores of FR group were much lower than that of F and R group( all P ＜ 0.05 ).No other adverse effects were observed.ConclusionIntra-articular administration of ropivacaine with fentanyl could provide superior postoperative analgesia without side effects.It was an excellent regimen for analgesia after knee arthroscopy.

Objective To investigate the clinical application of acupuncture combined with general anesthe -sia in gynecologic laparoscopic surgery .Methods 60 ASA( the American society of anesthesiologists )Ⅰ-Ⅱpatients undergoing elective gynecologic laparoscopic surgery were randomly divided into the acupuncture group and control group.Patients in the acupuncture group were chosen Hegu (LI 4),Neiguan(PC 6) on both sides.After acupuncture, the two acupoints,electroacupuncture stimulated 20-30min,then administered general anesthesia ,electroacupuncture until surgery finished ,the control group received general anesthesia only .The drug dosages of the two groups was regu-lated,maintained anesthesia depth bispectral index ( BIS) between 40 and 60.The changes of the blood pressure ( BP) ,heart rate and BIS of the two groups at the same time points were observed;the propofol and remifentanil dos-age after the surgery ,the awaken time and extubation time ,OAA/S score and pain score after wake ,the happening of restlessness,chills,nausea and vomiting ,the usage of narcotic analgesics postoperation ,and the intraoperative aware-ness were recorded .The effect of acupuncture combined with general anesthesia was evaluated .Results Anesthetic dosage propofol of the acupuncture group [(7.44 ±1.30)μg· kg-1· h-1] was less than [(8.66 ±1.24)μg· kg-1· h-1] of the control group (t=3.720,P=0.001),remifentanil dosage was also less than the control group [acupunc-ture group (10.59 ±2.58)μg· kg-1· h-1,control group (11.93 ±2.27)μg· kg-1· h-1,t=2.168,P=0.034]. Compared with the basic value ,the BP values were higher at the time of intraoperation ,waking,extubation and 10 min after extubation (all P<0.05),the acupuncture group had more stable BP .Compared with the acupuncture group , heart rates in the control group were faster at extubation and 10min after extubation .Recovery time and extubation time of the acupuncture group were (9.05 ±2.36)min and (1.61 ±2.40)min,which were shorter than (12.50 ± 3.20)min and (15.90 ±3.37)min of the control group (P<0.05).Pain score(VAS) in the acupuncture group was lower than that of the control group .Consciousness score was higher in the acupuncture group ,the incidence rates of restlessness,chills were less.Conclusion The use of acupuncture combined with general anesthesia in gynecologic laparoscopic surgery can reduce the dosage of general anesthetics ,shorten the awaken time and extubation time ,increase the OAA/S score of the patients ,relieve pain ,and the recovery quality is higher .

Objective To evaluate the therapeutic effect of extra-fine choledochoscope in treating polypoid lesions of gallbladder by percutaneous trans-hepatic and trans-gallbladder puncture(PTGB). Methods Extra-fine choledochoscope(2. 7 mm diameter)was inserted into tract soon after it was made per-cutaneously trans-hepatic and dilated in one session,gallbladder polyps was removed with biopsy forceps or snare or basket,and PTCD drainage tube(10. 2 F diameter)was imbedded for external drainage until 10 days after. If the gallbladder puncture point fell on the bed and gallbladder polyps were not clearly visual-ized,or puncture points were on non-gallbladder bed of the body,drainage tube(10. 2 F diameter)was placed for external drainage. Results Forty-two patients were successfully punctured,and 40 patients were punctured accurately on the bed in,and the fresh endoscope tract of these patients was established in 45 mi-nutes on average. Of the 29 cases of simple bottom and body ventral polyps,complete clearance of gallbladder polyps was achieved in 27. Gallbladder polyps clearance rate was 93. 10%. Complications of minor hemobi-lia occurred in 9 cases,and infection of biliary tract occurred in 3 cases after operation. There was no recur-rence after a follow-up of 15 months on average. Conclusion Extra-fine choledochoscope by PTGB is a less invasive,more reliable and effective method to cure benign polypoid lesions of the gallbladder. The gallblad-der is preserved and for malignant polyps,it can help to achieve early diagnosis and provide reliable evidence for further treatment.
