Objective To investigate the effects of compound lidocaine cream applied to tracheal tube on the recovery of tonsil with adenoidectomy in general anesthesia. Methods 120 patients undergoing elective tonsillectomy with adenoidectomy were randomly divided into the experimental group and the control group. In the experimental group, the surface of the tracheal tube was uniformly coated with compound lidocaine cream before anesthesia. In the control group, paraffin oil was given evenly to the surface of the tracheal tube. The changes of hemodynamics and the incidence of complications in the two groups were observed and recorded. Results The indexes of hemodynamics in the experimental group were more stable than those in the control group, and the control group had poor tube resistance, and the incidence of complications such as cough, irritability and sore throat was increased (P<0.05). Conclusion Application of compound lidocaine cream on tracheal tube surface can effectively reduce the cough and other stress response during the general anesthesia recovery period, decrease postoperative irritability and improve the safety of children after surgery.

Objective To discuss the efficacy and safety of transurethral plasmakinetic resection of the prostate(PKRP) for benign prostatic hyperplasia(BPH).Methods A British made Bipolar plasmakinetic resection system(Gyrus) was employed in this series.Started from the 6 o’clock point,the middle lobe of the prostate was resected,followed by the left and right lobes,which were resected down to the prostate capsule.And then the bladder neck was cut down.The apical tissues were resected to the anterior border of the seminal colliculus.After the operation,a F22 three-channel catheter was indwelled for 3 to 5 days after the operation,and a balloon was place in the bladder neck.Results The procedure was completed successfully in all of the cases with a mean operation time of(85.0?12.0) min,and a median blood loss 115.0 ml(30 to 650).Ten patients received blood transfusion during the operation(200 to 400 ml).No case showed transurethral resection syndrome or obturator nerve reflex.Fourteen patients developed inflammatory stricture of the anterior ureter and was then cured by dilating the urinary tract;15 cases showed transient urinary incontinence and was cured after pelvic floor muscle training for 1 to 3 weeks.Follow-up was available in the patients for 1 to 6 months,during which the mean Qmax of the patients significantly increased compared to that preoperation [from(7.6?2.4) ml/s to(22.6?3.4) ml/s,t=13.582,P=0.000),and the IPSS and life quality score markedly decreased [from 27.3?1.5 and 4.3?0.4 to 7.0?1.2 and 2.1?0.8;t=16.394 and 9.761,P=0.000 and 0.005,respectively] Conclusion PKRP is an effective and safe treatment for BPH.

Objective　To investigate the relationship between the apnea events and the correspondent sleep stage. Methods 68 normal volunteers were studied with polysomnography to confirm the sleep stage of the apnea events. Results Sleep apnea events were found in each different sleep stage. The events happened frequently in light sleep stage, most in stage 2. There were no significant sleep stage distribution difference in different sex .The number and severity of apnea events were also not relative with the sleep stage distribution. Conclusion Apnea events happened most frequently in light sleep stage. The reason is still unclear.

Objective To observe the effect of subarachnoid block with 0.5% bupivacaine at different temperatures during cesarean section.Methods 100 cases of elective cesarean section were randomly divided into room temperature group and heating group,50 cases in each group.Room temperature group: bupivacaine hydrochloride injection and glucose injection equilibrated group in a constant temperature thermostatic bath of 24 degrees thermostatic bath heating for above 30 min.Heating group: bupivacaine hydrochloride injection and glucose injection heated in the constant temperature thermostatic bath of 37 degrees thermostatic bath heatingfor above 30 min.Anesthesia was injected into the subarachnoid space at different temperatures to observe the anesthetic effect.Results The anesthesia increased rapidly, and the analgesia and muscle relaxation effects were better in the heating group than room temperature group, but the heating group had hypotension rate was higher than the room temperature group (36.0% vs.16.0%).There was no obvious difference between the incidence of adverse reactions such as nausea and vomiting in both groups.Conclusion Different temperatures of bupivacaine can be used safely for section anesthesia.The anesthesia effect of the heateding bupivacaine is faster, the anesthesia level is higher, the anesthesic and muscle relaxant effect is better.Bupivacaine at room temperature has relatively small effect on hemodynamics.

BACKGROUND: Quite a number of in vitro experiments indicate that low dose He-Ne laser can stimulate the cell growth and blood vessel regeneration therefore to improve the damages caused by ischemia. However, it needs further study on the in vivo experiments.OBJECTIVE: To study the protective effects of intravascular low dose laser irradiation to ischemic reperfusion of rats and explore its mechanism.DESIGN: A randomised and controlled trial based on experinental animals.SETTING: Department of Neurology of a hospital of a university.MATERIALS: The experiment was completed in the Surgery Experimental Animal Center of West China Hospital of Sichuan University. Healthy male SD rats of class Ⅱ which aged between 5 to 6 months with weight of 372 to 418 grams[mean weight(388.48 ± 10. 57) g] were provided by Animal Research Center of Sichuan University.INTERVENTIONS: Middle cerebral artery ischemia model of rats was prepared. Forty SD rats were randomly divided into treatment group and control group with each of 20 rats. Intravascular low dose He-Ne laser irradiation was conducted to rats in treatment group one time every other day, 20 minutes per time and 3 times for a course. Vein puncture was conducted to rats in control group without laser input.MAIN OUTCOME MEASURES: Ratio of infarcted volume RESULTS: The ratio of the cerebral infarction volume in treatment group was (10.43 ± 1.04) and is much lower than that of control group(16.78 ± 1.12).There was statistical difference between two groups( t = 27.14, P ＜ 0.05).CONCLUSION: Intravascular low dose He-Ne laser irradiation has protective effects to cerebral ischemia of rats.
