摘要： Study ObjectiveTo examine whether utilizing a salaried surgical first assistant or a physician as an assistant during gynecologic robotic cases affects surgical variables. DesignRetrospective chart review. SettingCommunity Practice Setting in Las Vegas, Nevada. Patients or ParticipantsFemale patients undergoing robotic surgical intervention for any gynecologic reason from 2005-2018 by a single gynecologic oncologist(n=1,690). InterventionsN/A Measurements and Main ResultsA high volume gynecologic oncologist's robotic case data spanning fourteen years (2005-2018) was analyzed. We separated the cases based on the type of assistant used, either an employed surgical first assist or another physician. The assisting physicians were either members of the same practice or general gynecologists in the community. The two groups were compared for operative time and estimated blood loss. We controlled for patient Body Mass Index, uterine weight, use of the fourth robotic arm, benign versus cancer pathology, and a subjective estimate of the difficulty of the case using a conventional laparoscopic versus robotic approach. Cases with an employed surgical assist had a mean adjusted robotic console time that was 0.32hrs(19.2min) faster than cases with a physician as the assist (95% CI 0.26hrs to 0.37hrs faster, p<0.001). Cases with an employed surgical assist also had an EBL that was 47.5cc lower than cases with a physician assisting (95% CI 38.8cc to 56.3cc lower EBL, p<0.001). ConclusionThe use of an employed surgical assist was associated with a faster console time and lower blood loss compared to using an available physician even adjusting for confounding factors. This deserves further exploration, particularly in regards to complication rates, operating room efficiency, utilization of health care personnel, and cost.

关键词： 标本溶血   骨折   生化指标检验  

摘要： 探究为骨折患者标本溶血进行生化检验其结果的价值和影响。方法:在2018.6年~2020.6年中选择120例患者展开评价和判定,根据标本溶血与否分为观察组和对照组。观察组骨折患者和对照组的骨折患者,均进行生化指标常规检验,共计17个项目,并将两组指标变化情况展开评估。结果:观察组各项生化指标检验结果较之对照组具有较为显著的差异(P<0.05)。结论:标本是否存在溶血对于骨折患者生化检验指标结果具有一定程度的影响,因此,需要加强血液采集与管理的监管力度,提高生化指标检验质量从而使得生化指标检验的结果具有较高的精确性和有效性。

摘要： 最近几年,科学技术的迅猛发展,临床检验技术随之产生,各种全新的生化分析仪器越来越多,而这些发展和进步都是为了获得更加准确的检验结果。在以往临床生化检验的过程中,所使用到的样本主要为血清样本,在对血清样本进行处理的过程中,通常需要花费大量时间来实行血清分离操作,并且,在实行分离操作的过程中,血清会产生纤维蛋白凝丝,这些凝丝的产生很有可能会对加样器或者仪器管路进行堵塞,会在一定程度上对医生的诊断和治疗带来不利影响。

关键词： 细菌学检验   宫颈癌   腔内放疗   局部感染  

摘要： 目的观察细菌学检验在宫颈癌腔内放疗合并局部感染患者临床治疗中的应用价值。方法用"信封法"将我院106例宫颈癌腔内放疗合并局部感染患者随机分入对照组及观察组,对照组由临床医师根据患者病症、病情变化评估其局部感染程度,并结合自身临床经验给予抗生素治疗,观察组患者通过其细菌学检验结合、患者病症及病情变化制定个体化抗生素用药方案,对比两组患者的感染治疗周期、病情控制时间及并发症发生率。结果观察组患者的感染治疗周期及病情控制时间比对照组短,分泌物增加、血性分泌物、盆腔炎及宫腔积液的发生率均比对照组低(P<0.05)。结论对宫颈癌腔内放疗合并局部感染患者应用细菌学检验来调整其抗生素用药方案可缩短其病情控制时间,降低相关并发症的发生率,值得推广.

摘要： It is commonly assumed that a higher oxygenated content on the surface of carbon fibers will lead to high interfacial adhesion. Thus, carbon fibers are exposed to oxidizing treatments to increase surface polarity. Here, we examine the interfacial interactions of a range of thermoset and thermoplastic polymers with carbon fibers that have a grafted polyethylene oxide (PEO) chains to their surface. This provides an extremely hydrophilic surface, without potential degradation of the fiber via chemical oxidation. We find that high surface polarity does not always correlate to high interfacial adhesion; in some instances, unsized hydrophobic carbon fibers possess equal or better fiber-to-matrix adhesion than treated hydrophilic carbon fibers. The most notable example is in vinyl ester resin, in which the presence of an alkyne group, able to participate in the radical polymerization process, provides significant improvements in interfacial shear strength (IFSS) compared to a larger, and polar, PEO chain.
