Introduction: In recent decades, the cost of postoperative pain has been the subject of many studies based on protocols developed by scientific societies for its assessment and optimization. At the Regional Hospital of Saint-Louis (Senegal), several protocols have been developed for pain management, but no study has focused on the assessment of postoperative pain management specifically. We therefore initiated this work, the objectives of which were to remind the neuroanatomical and neurophysiological bases of postoperative pain, and to analyze the assessment and management of this pain in patients who have undergone a caesarean section. materials and methods: This was a prospective and descriptive study, which took place in the gynecology-obstetrics department, over a period from January 2019 to July 2020. All patients who gave birth by cesarean section were included. The data was collected from a survey sheet written for this purpose. For each of the patients, the information was taken every day throughout the duration of postoperative hospitalization. Results: It appears from our work that after a cesarean section, the pain felt evolves on the first postoperative days with a peak during the second day. As in the data reported in the literature, there does not seem to be a difference in terms of pain intensity and analgesia dosage between scheduled and emergency caesarean sections. However, young age and female gender—for other types of surgeries—are risk factors associated with high postoperative pain scores. This trend is probably related to the low pain experience of tested patients. Our initial hypothesis was that acute post-operative pain after caesarean sections could be linked to defects in the perception and processing of pain by caregivers. Indeed, we have shown that awareness-raising, information, and training actions have made it possible to significantly improve the management of pain after a cesarean section. Conclusion: After a cesarean section the p

This article examines the dynamics for stochastic plate equations with linear memory in the case of bounded domain. We investigate the existence of solutions and bounded absorbing set by using the uniform pullback attractors on the tails estimates, and the asymptotic compactness of the random dynamical system is proved by decomposition method, and then we obtain the existence of a random attractor.

近年来,石油类有机污染物引起的地下水污染状况日趋严重,在传统原位化学氧化修复技术中,药剂的迁移扩散受含水层渗透性及非均质性的影响显著,寻求行之有效的原位增渗方法是提高修复药剂影响半径以及污染物修复效率的关键所在。超声波增渗技术具有对环境扰动小、无二次污染及装置简单易安装等优势,被广泛应用于改善煤岩和油层渗透率等领域,以此提高煤气和石油采收率。然而将超声波作为增渗技术应用于地下水原位修复领域的报道甚少,增渗效果和修复机理仍然有待深入研究。通过对两种不同的含水介质施加超声波作用,对比分析超声前后介质中孔径及孔隙连通性的变化、高锰酸钾的运移速率以及苯酚的降解效率,阐明超声波原位增渗的作用机理和影响因素,并探讨基于超声原位增渗下有机污染物的降解动力学。结果表明,影响超声波原位增渗效果及有机物污染物降解效率的主要因素有超声作用功率、介质粒径、超声波作用模式以及地下水流速等。超声波原位增渗效果会随着超声作用功率和介质粒径的增大而增强,通过对介质施加500 W的超声波作用150 min,可最大程度地提升高锰酸钾的运移速率达3.02倍;此外,当地下水流速为8.59 cm·d^(-1)时,超声波预处理作用方式可最大程度将苯酚降解率从78.61%提升至91.45%。本研究通过探索超声波原位增渗对修复药剂传输速率以及污染物修复效率的作用机理,可为开拓地下水原位修复技术的应用前景提供可靠的理论依据和技术支持。
