目的探究创伤骨科护理管理中疼痛管理的应用价值。方法 82例患者选取于2017年6月-2018年6月,所有患者均来源于本院骨科收治的住院患者,数字表为患者分组原则,常规组41例,疼痛组41例,分别予以常规护理、常规护理+疼痛管理,比较满意度、疼痛评分及平均住院时间。结果疼痛组满意度92.68%比常规组73.17%高,差异具有统计学意义(χ^2=5.513,P <0.05),患者干预后的疼痛评分低于常规组,平均住院时间短于常规组,差异存在统计学意义(P<0.05)。结论疼痛管理用于创伤骨科护理管理中,患者疼痛明显减轻,患者满意度高,缩短了患者的平均住院时间。 相似文献

Chronic obstructive pulmonary disease (COPD) is a significant health problem in developed countries. We aimed to estimate the prevalence of COPD in a single Spanish healthcare area. We also aimed to assess if there are any differences in prevalence and spirometry use among primary care services by utilizing already registered information. We designed a cross-sectional study to determine the prevalence of COPD and the performance of spirometries in each primary care service. A total of 8,444 patients were diagnosed with COPD, with a prevalence of 2.6% for individuals older than 39 years. The prevalence increased with age and was much higher in men. Significant heterogeneity was found in the prevalence of COPD and spirometry use among primary care services. COPD was underdiagnosed and there was wide variability in spirometry use in our area. Greater efforts are needed to diagnose COPD in order to improve its clinical outcomes and to refine registries so that they can be used as reliable sources of information 相似文献

《Seminars in Arthroplasty》2015,26(1):28-33
While use of large heads in total hip arthroplasty (THA) continues to grow, concerns have been raised regarding anterior hip pain resulting from impingement of the prosthetic head against soft-tissues like the iliopsoas. To address these concerns, a new anatomically contoured head (ACH) was developed. In this study cadaver tests were utilized to show that iliopsoas impingement/tenting caused by conventional heads is significantly relieved with the more rounded and reduced distal profile of the ACH. Thus, the ACH implant may be able to decrease the risk of soft-tissue impingement with conventional heads, particularly in the smaller hip. 相似文献

目的 对比LEEP刀与微波治疗慢性宫颈炎的临床效果.方法 随机选取2013年10月—2015年4月期间,到该院就诊的70例慢性宫颈炎患者为研究对象,在取得患者同意的前提下,随机将患者均分为对照组(采用微波治疗)和观察组(采用LEEP刀治疗),两组患者的人数均为35例,观察并比较两组患者的手术情况、治疗效果等指标. 结果 ①观察组患者的手术时间、阴道流液时间、术中出血量均优于对照组,两组差异有统计学意义(P<0.05);②观察组患者的治疗总有效率为97.14%(34/35),对照组为82.86%(29/35),两组差异有统计学意义(P<0.05).结论 在慢性宫颈炎的治疗中,与传统微波治疗相比,LEEP刀治疗的效果更佳,值得临床推广. 相似文献

ObjectiveTo systematically review the literature related to the effectiveness of parents’ active involvement during painful interventions for their preterm infants.Data SourcesWe performed a systematic search of PubMed, EMBASE/Ovid, CINAHL, Livivio, and PsycInfo using the keywords “preterm infants,” “pain,” and “parents.”Study SelectionArticles were eligible for inclusion if they were published between 2000 and 2021 and reported randomized controlled trials (RCTs) in which preterm infants underwent painful interventions, and parents were present and actively involved in pain-reducing measures.Data ExtractionWe used the Consolidated Standards of Reporting Trials (CONSORT) checklist for RCTs for data extraction. We assessed methodologic quality using critical appraisal for RCTs according to the Joanna Briggs Institute.Data SynthesisIn total, 22 articles met the inclusion criteria. These articles reported 19 studies focused on kangaroo/skin-to-skin care, one focused on breastfeeding, and two focused on facilitated tucking. The methods used to evaluate pain in the infant varied substantially. Overall, kangaroo/skin-to-skin care and facilitated tucking resulted in clinically and statistically significant decreases in pain. For breastfeeding, effectiveness was linked to a more mature sucking pattern of the preterm infant.ConclusionThe current evidence suggests that involving parents in pain-reducing measures during painful interventions for their preterm infants is beneficial. However, more research is needed for the different methods of involving parents in pain-reducing measures. 相似文献
