Assessing the Impact of General Anesthesia and Bronchial Intubation in Conjunction with Thoracic Paravertebral Nerve Block on Cellular Immunity and Surgical Management in Tuberculous Pyothorax Patients

Objective:This study aims to investigate the impact of combining general anesthesia with bronchial intubation and thoracic paravertebral nerve block during surgery for patients with tuberculous pyothorax.Methods:Eighty patients diagnosed with tuberculous pyothorax,admitted to the hospital between January 2023 and September 2023,were randomly selected for this study.The patients were divided into control and study groups using a numerical table method.The control group underwent general anesthesia with bronchial intubation,while the study group received general anesthesia with bronchial intubation in conjunction with thoracic paravertebral nerve block.Subsequently,the patients were monitored to assess mean arterial pressure,heart rate variations,and adverse reactions to anesthesia.Results:The study group exhibited significantly lower mean arterial pressure and heart rate levels during the post-surgical incision,immediate end of surgery,and immediate extubation periods compared to the control group(P<0.05).Furthermore,the Ricker and Ramsay scores in the study group were significantly lower than those in the control group(P<0.05).Conclusion:The combined use of general anesthesia via bronchial intubation and thoracic paravertebral nerve block has been found to stabilize mean arterial pressure and heart rate while providing effective sedation for surgical treatment in patients with tuberculous septic thorax.

校长信息化领导力对教师信息技术应用行为的影响研究——基于42篇实证研究文献的元分析

在"互联网+"时代,人们对教师有效应用信息技术变革传统课堂教学、提升教学质量充满期待。校长作为信息化教学变革的引领者,其领导力是影响教师有效应用信息技术的关键要素。为探究校长信息化领导力对教师信息技术应用行为的影响,国内外众多学者开展了大量实证研究,但研究结论却尚存争议,有待进一步考证。本文采用元分析方法,以近15年间发表的42篇实证研究文献为基础,审视与分析校长信息化领导力对教师信息技术应用行为的影响效果,并对相关调节变量的效应差异进行了探究。研究表明:校长信息化领导力对教师信息技术应用行为具有较弱的正向影响,技术伦理、人际沟通与设施供给影响作用较大,专业发展与愿景领导影响作用适中,教学评估影响效果最小;校长信息化领导力对教学效能与技术整合度影响较大,对应用态度和应用技能影响较小;校长信息化领导力影响效应在性别、教龄、学段上都具有显著差异,就性别而言对男教师影响略高于女教师,就教龄而言对熟手教师负向影响更大,就学段而言对大学和小学教师影响较明显,对中学及混合教师影响适中,对幼儿教师影响最弱。结合研究结论及自身工作经验,就教师有效应用信息技术问题提出了若干条理论与实践层面的策略建议与愿望设想,以期能够对学术研究与实践有参考价值。
