International Eye Science 2014;(10):1868-1870
AIM:To discuss the application effect of adjustable sutures in glaucoma filtering operation after trabecular resection.
METHODS: Seventy-eight cases ( 101 eyes ) suffered from glaucoma were randomly divided into two groups, observation group and control group. Thirty-nine cases ( 51 eyes ) in the observation group underwent trabeculectomy with adjustable sutures, the control group (39 cases, 50 eyes) only adopted trabeculectomy.RESULTS: Compared Preoperative IOP in two groups, the difference was not statistically significant (P>0. 05). After 6mo, IOP were decreased compared with preoperative in two groups, and that in observation group was lower than control group, the difference was statistically significant ( P < 0. 05 ). Six months after operation, there were 1 eye with shallow anterior chamber Ⅰ and 2 eyes with non- functional bleb in observation group, and the complication rate was 5. 9%. While there were of 6 eyes with shallow anterior chamber, in which 4 eyes at gradeⅠ, each one at gradeII and Ⅲ. Non-functional blebs in 5 eyes and a scleral flap adhesion complications rate in the control group was 24. 0%, significantly higher than that in the observation group, the difference was statistically significant ( P<0.01).
CONCLUSION: The adjustable sutures combined with trabeculectomy for glaucoma can significantly reduce the postoperative complications. The curative effect is exact and clinically applicable.

OBJECTIVE:To investigate the postoperative analgesic effect of Dexmedetomidine combined with Remifentanil on patients in lung cancer resection and its effect on immune function. METHODS:60 lung cancer patients in lung cancer resection were randomly divided into control group(30 cases)and observation group(30 cases). All patients with endotracheal intubation re-ceived lung cancer resection under general anesthesia. After surgery,control group received Remifentanil hydrochloride 10μg/(kg·d)+Ondansetron hydrochloride injection 16 mg,adding into 0.9% Sodium chloride injection co-formulated into 100 ml;observation group received Dexmedetomidine hydrochloride injection 0.75 μg/(kg·d)+Remifentanil hydrochloride 10 μg/(kg·d)+Ondansetron hydrochloride injection 16 mg,adding into 0.9% Sodium chloride injection co-formulated into 100 ml. Background doses in 2 groups were 2 ml/h,self-controlled amount was 2 ml,lockout time was 15 min. Visual analog pain score (VAS),IFN-γ,IL-10 level,T cell subsets(CD3+,CD4+,CD8+,CD4+/CD8+)after 6,12,24,48 h and the incidence of adverse reactions in 2 groups were observed. RESULTS:VAS scores after 6,12,24,48 h in observation group were significantly lower than control group,and VAS scores after 24,48 h in 2 groups were significantly lower than that after 6 h,with statistical significance(P<0.05). IFN-γ levels after 6,12,24,48 h in observation group were significantly lower than control group,and IFN-γ levels after 12,24,48 h in 2 groups were significantly lower than that after 6 h,IL-10 level after 12,24,48 h in observation group were significantly higher than that 6 h and control group,with statistical significance(P<0.05). CD3+after 6,24,48 h,CD4+after 6,12,48 h,CD4+/CD8+af-ter 12,24,48 h in observation group were significantly higher than control group,CD8+ after 12,24 h were significantly lower than control group,CD3+,CD4+ after 12,24,48 h in 2 groups,CD4+/CD8+ in control group,and CD8+ after 12,24 h in observa-tion group and after 24 h in control group were significantly lower than that after 6 h,with statistical significance(P<0.05). There was no significant difference in the incidence of adverse reactions in 2 groups(P>0.05). CONCLUSIONS:The postoperative anal-gesic effect of Dexmedetomidine combined with Remifentanil on patients in lung cancer resection is superior to Remifentanil alone, it can improve the immune function,with good safety.
