目的:探讨快速康复外科(ERAS)护理策略在老年股骨转子间骨折病人手术室护理中的应用效果。方法:随机抽样法选取2017年1月—2018年12月医院100例老年股骨转子间骨折手术病人,使用随机数字表法分为对照组与研究组各50例。对照组采用常规手术室护理,研究组采用手术室ERAS护理。比较两组病人体温(术前、术中、术后)、术中出血量、住院时间、生理应激指标、心理应激状况、术后住院期间并发症发生情况。结果:研究组病人术中、术毕体温高于对照组,术中出血量少于对照组,住院时间短于对照组(P<0.05);干预后研究组病人心率、收缩压、舒张压低于对照组,SAS、SDS评分低于对照组(P<0.05);研究组病人术后并发症发生率仅为4.00%,低于对照组的18.00%(P<0.05)。结论:老年股骨转子间骨折手术室护理中应用ERAS护理可减轻病人手术应激反应,促进术后恢复,预防相关并发症。 相似文献

BackgroundThe use of continuous positive airway pressure (CPAP) applied early after birth improves several outcomes when compared with intubation and invasive mechanical ventilation. “Early CPAP” protocols vary in relation to the pressure level, type of interface used, and studied sample.ObjectiveThis study compared intubation rate, exogenous surfactant use, and hospitalization length (among other variables) prior to and after adopting an “early CPAP” protocol in preterm infants with gestational age between 28 and 32 weeks, using intermediate pressures and short binasal prongs.MethodsThis was a retrospective study conducted in a public university hospital in Brazil. All preterm infants with gestational age between 28 and 32 weeks were included in the study. The newborns born between January 2011 and December 2012, prior to the protocol being implemented, were considered the historical control group, and those born after implementation, between February 2013 and August 2014 were considered the intervention group.ResultsThe participants in both groups had similar baseline characteristics (p > 0.05). There were significant reductions in intubation rate (89% versus 73%, p = 0.02), exogenous surfactant use (86% versus 67%, p = 0.02), and median (Q1 - Q3) days of invasive mechanical ventilation [4 (2 - 14) versus 1 (0.15–9), p = 0.01] and length of hospital stay in days [56 (42–77) versus 42 (35–71), p = 0.02].ConclusionsThe findings demonstrate positive outcomes of the early CPAP protocol. This protocol used simple and affordable equipment available in the hospital which could easily be reproduced in other centers, generating better outcomes for preterm infants and reducing hospital expenses. 相似文献

目的:研究探讨手术室护理对胸腔镜食管癌根治术的护理效果及护理方法。方法:选取2014年3月~2016年10月在某院接受治疗胸腔镜食管癌根治术的68例患者进行护理研究,将其随机分为观察组和对照组两组,每组34例。给予观察组患者综合的手术室护理,给予对照组患者常规的手术室护理,对比两组患者的手术成功率以及术后恢复情况。结果:观察组手术成功率与患者护理满意度均高于对照组,两组有明显差异,有统计学意义(P<0.05)。结论:对接受胸腔镜食管癌根治术的患者进行综合手术室护理能够有效提升患者的手术成功率,提高患者护理满意度,综合手术室护理方法具有护理推广意义。 相似文献

Purpose: On time start of the first surgical case improves operating room (OR) utilization, physician, and patient satisfaction and decreases delays in subsequent cases. The goal of our study was to evaluate the effect of a multidisciplinary initiative to improve first patient in the room (FPIR) and first case on time start (FCOTS) metrics in a tertiary care setting. Materials and Methods: A multidisciplinary committee focused on first case start data collection. Reasons for both anesthesia and surgical delays were analyzed. Improvement efforts focused on the timely completion of surgical consent, a requirement of a surgical, anesthesia, and nurse team member presence at the patient's bedside by specific time, and parallel processing in the OR. Results: Over 65,100 OR cases were analyzed between 2007 and 2014. There was a statistically significant improvement in FPIR (82.80% versus 69.60%, p < .0001) and FCOTS (66.60% versus 55.90%, p < .0001). Surgical consent completion rate increased from 35% baseline to 68%–100%, depending on the surgical subspecialty. Improvements appeared sustainable several years following process implementation for both FPIR (84.60% versus 69.60%, p < .0001) and FCOTS (67.60% versus 55.90%, p < .0001). Conclusions: Our study demonstrates a successful targeted, multidisciplinary initiative to improve first case surgical starts in an academic setting. Our approach was organizational rather than punitive or rewarding on an individual basis. Strategies included establishing concrete, time-specific goals and posting them visibly, empowering individuals to fulfill them, and ensuring no compromise in patient safety. In the complex environment of academic medicine including research protocols and teaching in the ORs, our organizational approach proved sustainable over several years. 相似文献

目的:了解不同等级医院对手术室专科护士的需求,探索能满足不同等级医院手术室护理工作实际需求的专科护士培训方案。方法自行设计调查表,选择在江苏省手术室专科护士培训基地学习的80名手术室护士进行调查。调查内容包括一般资料、所在医院三级学科和亚专业学科细化情况、参加专科护士培训后工作状况、手术室专科护士的培养模式和按照三级学科培养手术室专科护士的实施方案4个方面。结果80名护士均认为有必要开展手术室专科护士培训,80.00%的人认为目前模式属手术室全科护士的培训;72.22%的二级医院的护士认为参加培训学习的理论知识、参加的临床实践技能能满足工作需要,可继续采取目前培养模式;74.19%的三级医院的护士认为培训知识尚能满足工作需要,但针对自己的三级学科方向还不够强、不够细,应该按照三级学科培养手术室专科护士。结论根据不同等级医院手术室护理工作的实际需求,建立统一招生、同步培训、分层培养的统分结合培养模式,能培养适应不同等级医院手术室需求的专科护士。 相似文献

Migraine is a common disorder that starts at an early age and takes a variable pattern from intermittent to chronic headache with several exacerbations throughout a lifetime. Children and adolescents are significantly affected. If an acute headache is not aborted by outpatient migraine therapy, it often causes severe disability, preventing the child from attending school and social events. Treating the acute severe headache aggressively helps prevent prolonged disability as well as possible chronification. Multiple medications are available, mostly for the outpatient management of an attack and include the use of over‐the‐counter anti‐inflammatory medications as well as prescribed medications in the triptan group. These therapies do sometime fail and the exacerbation can last from days to weeks. If the headache lasts 72 hours or longer it will fall in the category of status migrainosus. Status migrainosus is described as a severe disabling headache lasting 72 hours or more by the ICHD3 criteria. Disability is a major issue in children and adolescents and aggressive acute measures are to be taken to control it as soon as possible. Early aggressive intravenous therapy can be very effective in breaking the attack and allowing the child to be quickly back to normal functioning. This article reviews what is available for the treatment of pediatric primary headaches in the emergency room. 相似文献
