复方角菜酸酯栓在痔上黏膜环形切除钉合术后的临床应用评价 总被引:6,自引:0,他引:6
目的评价复方角菜酸酯栓对缓解痔上黏膜环形切除钉合术(PPH)后患者早期不适症状方面的疗效。方法选取2002年11月至2003年7月行PPH的80例患者,随机分为治疗组(复方角菜酸酯栓组,42例)和对照组(常规处理组,38例),分别记录两组患者术后24h和第6及第12天时的症状改善情况、术后24h有无尿潴留情况、术后首次排便时间、试验结束时伤口愈合情况、住院时间和换药次数、停药及停药的原因以及伴随用药情况。结果术后24h治疗组患者症状总得分(4.4)较对照组(6.1)低,P<0.05。但至术后第6和第12天时,两组症状得分比较,差异无统计学意义(P>0.05)。治疗组患者在各时间点的症状得分减少值均高于对照组(P<0.05)。两组患者在术后24h出现尿潴留的比率和住院天数方面比较,差异无统计学意义(P>0.05)。结论复方角菜酸酯栓对于缓解PPH术后早期的不适症状效果良好。 相似文献

目的探讨二尖瓣置换合并射频迷宫术的体外循环 (CPB)方法。方法 :76例风湿性心脏二尖瓣病变合并房颤患者实施瓣膜置换时 ,采用心内直视射频消融迷宫术对其合并的心房纤颤予以治疗。先期的 13例 (A组 )患者在CPB转流阻闭升主动脉后进行射频消融术和二尖瓣置换 ;后期 6 3例 (B组 )采用阻断上下腔静脉后先射频消融右心房 ,再行二尖瓣置换和左房射频消融。结果 :A组 13例患者CPB转流 (10 4± 2 5 )min ,主动脉阻断 (6 1± 11)min。B组 6 3例患者CPB转流 (81± 19)min ,主动脉阻断 (47± 11)min ;应用冷晶体心肌保护患者开放升主动脉后心脏自动复跳率 5 5 .9% ,应用冷血心肌保护患者心脏自动复跳率 71.4 %。术后恢复窦性心律 6 4例 ,占 84 .2 %。结论 :在二尖瓣置换合并射频迷宫术的体外循环中阻闭升主动脉前先射频消融左房可以明显缩短体外循环时间和主动脉阻断时间 ;应用冷血心肌保护液可以加强心肌保护效果且射频消融迷宫术治疗顽固性房颤效果明显 相似文献

Rita Noumeir 《Journal of digital imaging》2005,18(4):260-269
A few years ago, the Digital Imaging and Communications in Medicine standard introduced a network transaction that is initiated
by modality equipment, mainly at the beginning and at the end of the acquisition. This transaction, the Modality Performed
Procedure Step (MPPS), is sent to the Picture Archiving and Communication System and/or to the Radiology Information System.
It carries information about what really has been performed by the modality equipment during acquisition. In this paper, we
present MPPS and discuss its benefits. We show how MPPS enables efficient radiology workflow and how it ensures accuracy and
completeness of imaging information. We think our paper helps bridge the gap between MPPS implementation and deployment. By
understanding all the MPPS benefits, the end user becomes aware of the great enhancement in patient care that this transaction
provides. 相似文献

BackgroundPlatelet transfusion is required to treat haemo-oncology or trauma patients. Platelet apheresis (PA) performed with apheresis equipment has increased rapidly in recent years. Leucocyte-reduced platelet apheresis (LRPA) can reduce the risk of platelet refractoriness and febrile nonhemolytic transfusion reactions (FNHTRs) for transfusion. Accordingly, this study aimed to investigate and compare the platelet metabolic and functional responses between PA performed with Haemonetics and LRPA performed with Trima Accel cell separator.MethodsThe qualities of platelets collected through PA and LRPA were evaluated in terms of visual appearance, morphology, platelet-aggregation changes, metabolic activities, and bacterium-screening test during 5-day storage. Statistical analyses included two-sample t-test and generalised estimating equation(GEE) method.ResultsDuring 5-day storage in LRPA, residual leucocytes were all <1.0×106, and the parameters of platelet function were as follows: platelet aggregated to agonists such as adenosine 5′-diphosphate (ADP) and collagen, and the extent of shape change and pO2 showed no statistically significant difference between PA and LRPA. The hypotonic shock reaction (HSR) on days 0, 1, and 3 were significantly higher in LRPA than in PA (71.78±6.92 vs. 64.10±7.42; P=0.002; 71.53±8.98 vs. 62.96±9.84; P=0.007; 68.05±7.28 vs. 57.76±6.80; P<0.0001, respectively). Values of mean platelet volume (MPV) were statistically larger in PA than in LRPA on days 0, 1, and 3. On day 5, the swirling score was higher in LRPA than in PA. The mean lactate levels had no statistically significant difference between PA and LRPA. Moreover, no growth was observed through bacterium-screening test conducted on 40 samples.ConclusionComparison of LRPA and PA products collected from the Trima Accel and Haemonetics automated blood-collection systems, respectively, revealed that both products possessed good platelet qualities even though additional processes are needed to reduce leucocytes. Furthermore, investigating the outcomes of other apheresis instruments with focus on the safety of donors, products, and recipients is necessary. 相似文献
