水银血压计袖带加压法在静脉充盈不足患者静脉穿刺中的应用效果

目的探讨水银血压计袖带加压法对静脉充盈不足患者静脉穿刺成功率的影响。方法选取颌面外科手术需行静脉穿刺输液的患者100例，采用随机数字表法分成两组，对照组（n=50）采用常规的橡胶止血带结扎止血法，观察组（n=50）采用缠绕银汞血压计袖带并加压止血法，比较两种方法静脉穿刺成功率及穿刺时间。结果观察组患者静脉穿刺一次成功率为88％，高于对照组的64％，两组比较差异有统计学意义（X2=7．895，P〈0．05）；观察组患者静脉穿刺总时间为（103．32±58．59）s，对照组静脉穿刺总时间为（118．10±79．07）S，两组比较差异无统计学意义（t=1．062，P〉0．05）。观察组中超重及肥胖患者27例，对照组22例。观察组超重及肥胖患者的一次穿刺成功率（96％）高于对照组（50％），两组比较差异有统计学意义（x2=14．051，P〈0．05）；观察组超重及肥胖患者静脉穿刺总时间为（98．70±34．10）s，对照组为（127．86±90．46）S。两组比较差异无统计学意义（t=1．548，P〉0．05）。结论在静脉穿刺点上方缠绕银汞血压计袖带并加压止血的方法能够提高静脉充盈不足患者的静脉穿刺成功率。

Objective To investigate the effect of mercury sphygmomanometer cuff on venipancture for under-filling veins.Methods A total of 100 patients who needed intravenous transfusion were chosen and randomly divided into two groups,each with 50 cases.The control group received conventional rubber tourniquet hemostasis while the control group received mercury sphygmomanometer sleeve wrapping and pressuring hemostasis,and two groups' success rate of venipancture as well as puncturing time were compared.Results The primary success rate of venipancture was 88％ in the control group,higher than 64％ in the control group,and the difference was statistically significant (x2 =7.895,P ＜ 0.05).The total puncturing time was (103.32 ±58.59)s in the control group and (118.10 ± 79.07)s in the control group,and the difference was not statistically significant (t =1.062,P ＞ 0.05).There were 27 overweight and fat patients in the control group and 22 in the control group.The primary success rate of venipancture for overweight and fat patients was 96％ in the control group,higher than 50％ in the control group,and the difference was statistically significant (x2 =14.051,P＜0.05).The total puncturing time for overweight and fat patients was (98.70 ± 34.10)s in the control group,and (127.86 ± 90.46) in the control group,and the difference was not statistically significant (t =1.548,P ＞ 0.05).Conclusions Mercury sphygrnomanometer sleeve wrapping and pressuring hemostasis can improve the success rate of venipancture for under-filling veins.
