Effect of dexamethasone combined with oxybuprocaine hydrochloride gel on prevention of postoperative sore throat after nasal endoscopy / 北京大学学报(医学版)

OBJECTIVE@#To explore the effectiveness and feasibility of dexamethasone combined with oxybuprocaine hydrochloride gel on the prevention of postoperative sore throat after nasal endoscopy.@*METHODS@#In the study, 60 patients with American Society of Anesthesiologist (ASA) physical statuses Ⅰ to Ⅱ, aged 18 to 72 years, scheduled for elective nasal endoscope surgery under general anesthesia requiring endotracheal intubation were randomly divided into dexamethasone combined with oxybuprocaine hydrochloride gel group (G group, n=30) and control group (C group, n=30). The patients in the G group received dexamethasone 0.1 mg/kg before induction and the oxybuprocaine gel was applied to the endotracheal catheter cuff and the front end within 15 cm. The patients in the C group received the same dose of saline and the saline was applied to the endotracheal catheter cuff and the front end within 15 cm. Then, all the patients in the two groups received the same induction and anesthesia maintainance. The operation time, anesthesia time, emergence time, extubation time and departure time were recorded. The intraoperative infusion volume, blood loss volume, propofol, remifentanil, rocuronium dosage were also recorded. The adverse reactions such as intraoperative hypotension, bradycardia and postoperative agitation were recorded. The postoperative sore throat score was recorded at the end of operation and 4 h, 8 h, 12 h, and 24 h after operation.@*RESULTS@#Compared with the C group, the emergence time [(8.4±3.9) min vs. (10.8±4.7) min], extubation time [(8.8±3.7) min vs. (11.9±4.8) min], and departure time [(20.0±5.3) min vs. (23.0±5.8) min] were significantly shorter, and the propofol dosage [(11.8±1.8) mg/kg vs. (15.9±4.6) mg/kg], remifentanil dosage [(10.9±4.7) μg/kg vs. (14.1±3.6) μg/kg] were significantly less in the G group, and there was no difference of rocuronium dosage in the two groups. Compared with the C group the incidence of intraoperative hypotension [10%(3/30) vs. 30%(9/30)], bradycardia [16.7%(5/30) vs. 20%(6/30)] and postoperative agitation [6.7%(2/30) vs. 23.3%(7/30)] were significantly lower in the C group. The postoperative sore throat score at the end of operation, 4 h, 8 h, 12 h and 24 h after operation in the G group were significantly lower than in the C group respectively [0 (0, 1) vs. 1 (1, 2), 0 (0, 0) vs. 1 (1, 2), 0 (0, 0) vs. 1 (1, 2), 0 (0, 0) vs. 1 (0.75, 1), 0 (0, 0) vs. 1 (0, 1)].@*CONCLUSION@#Dexamethasone combined with oxybuprocaine hydrochloride gel was effective and feasible on the prevention of postoperative sore throat after nasal endoscopy.

Application of Oxybuprocaine Hydrochloride Gel in colonoscopy examination / 中国内镜杂志

Objective To explore the application of Oxybuprocaine Hydrochloride Gel in colonoscopy examination. Methods 1000 patients received colonoscopy examination were randomly divided into experimental group and control group, 500 cases in each. Oxybuprocaine Hydrochloride Gel was applied on anal region in the experimental group before endoscopy for perianal anesthesia and lubrication. Paraffin oil was used in the control group to lubricate perianal and enteroscopy. The success rate of primary insertion, visual analogue pain score (VAS) score, examination time and postoperative complications were compared between the two groups. Results In the experimental group, the success rate of primary insertion (95%) was higher than that of the control group (76%), and the pain score was lower than that of the control group.The examination time was shortened, and the difference was statistically significant (P < 0.05). Conclusions Oxybuprocaine Hydrochloride Gel applied to colonoscopy can effectively reduce the patient's pain and discomfort, improve the success rate of primary insertion, shorten the examination time. And the method is worthy of clinical popularization and application.

Clinical comparison of two kinds of analgesic methods used in artificial abortion / 重庆医学

Objective To compare the clinical application of phloroglucinol combined with oxybuprocaine hydrochloride gel and propofol in artificial abortion .MethodFouhundredcaseundergoing artificial abortion in ouhospital from January 2011 to Decembe2012 were randomly divided into the phloroglucinol group and the propofol group ,200 casein each group .The phloro-glucinol group waintramuscularly injected by phloroglucinol 80 .00 mg a30 .00 min before abortion ,and oxybuprocaine hydro-chloride gel 30 .00 mg by cervical injection a4 .00 min before operation .The propofol group waperformed the operation undethe general anesthesiof propofol combined with fentanyl .The cervical relaxation ,operative time ,pain degree ,intraoperative vaginal bleeding ,vaginal bleeding apostoperative 30 .00 min and occurrence rate of abortion syndrome were observed and recorded in the 2 group.ResultThe operative time ,analgesieffec,occurrence rate of abortion syndrome and operation coshad no statistically significandifferencebetween the two groups(P＞0 .05);buthe cervical relaxation ,dug,monitoring cosand occurrence of respi-ration suppression had statistically significandifferencebetween the two group(P＜0 .01) .Conclusion Phloroglucinol combined with oxybuprocaine can achieve the analgesieffecclose to thaof proprofol in artificial abortion ,ieconomiand practical withouneeding anesthesimonitoring ,and can be used in the primary hospital especially the hospitalwith lack of monitoring devices.
