Objective To assess the impact of multimedia teaching methods,standard patient teaching methods,case teaching methods,and surgical observation teaching methods on clinical probation in pediatric surgery．Methods Pediatric students participating in clinical probation in pediatric surgery in 2022 and 2023 were randomly assigned to either the experimental group or the control group,with 45 students in each group．The experimental group received diversified teaching methods,while the control group received traditional teaching methods．A comparison was made between the two groups regarding theoretical knowledge scores,skill operation scores,clinical knowledge scores,total scores,teacher-student satisfaction levels,and family satisfaction levels of pediatric students．Results The experimental group demonstrated significantly higher theoretical knowledge scores（P<0.05）,skill operation scores（P<0.05）,clinical knowledge scores（P<0.05）,and total scores compared to the control group．In terms of satisfaction evaluation criteria such as teaching style,learning interest,self-evaluation ability,teamwork skills and professional recognition of pediatric surgery（P<0.01）,the experimental group showed significantly higher levels than the control group．There was no significant difference between the two groups regarding teachers’ theoretical knowledge level and enthusiasm score（P>0.05）．However,the teachers in the experimental group scored significantly higher than those in the control group when it came to professional knowledge mastery,clinical practice ability,student learning enthusiasm,and teamwork skills（P>0.05）．Conclusions Implementing diversified teaching approaches during pediatric surgery clinical probation not only enhances theoretical understanding,skills development,and clinical expertise among pediatric students,but also improves overall satisfaction levels for both teachers and students as well as enhances professional recognition of pediatric surgery students．

目的 通过对婴幼儿泌尿系感染并发脓毒症的临床特点、病原菌情况及相关因素的分析,探讨其早期诊断和及时治疗的措施。方法 选取83例我科收治的确诊泌尿系感染合并脓毒症的婴幼儿作为研究对象,回顾性分析其临床表现、实验室检查及治疗预后情况。结果 所选婴幼儿均确诊泌尿系感染合并脓毒症,以男性患儿多见,全身中毒症状重,6月以下多以严重脓毒症、脓毒性休克为首诊表现,尿路刺激症状不明显。有明显细菌感染生物标记物的改变。细菌学培养共检出细菌22株,大肠埃希菌占54.55% (12/22),对头孢吡肟较为敏感,对亚胺培南、美罗培南全部敏感;屎肠球菌占22.73%(5/22),对万古霉素、利奈唑胺、替考拉宁敏感。结论 在婴幼儿常见的感染部位中,泌尿系感染容易被忽略。而小于6月的患儿更易并发严重脓毒症、脓毒症休克等危重症。因此,以脓毒症为首诊表现的婴幼儿应特别警惕泌尿系感染,尽可能早期明确感染部位,防止漏诊。首诊1小时内给予广谱抗生素治疗,可降低婴幼儿脓毒症的病死率,改善患儿预后。

Objective By analyzing the clinical features, laboratory tests, pathogenic bacteria culture and the treatments of infants and toddlers with urinary tract infection UTI accompanied with sepsis, we aim to guide the further clinical treatments and prevention. Methods We selected 83 cases from January 1, 2014 to December 31, 2016 in our hospital as the research objects which were accepted the diagnosis and treatments of urinary tract infection complicated with sepsis. Its clinical manifestations, laboratory tests, bacteriology examination and treatment prognosis were retrospectively analyzed. Results Among the selected infants and toddlers diagnosed with urinary tract infection complicated with sepsis, male patients were more common. Symptoms of systemic poisoning were observed in the majority especially in the children aging under 6 months, with severe sepsis and septic shock as the first manifestation, while conventional symptoms were not obvious. Biological markers of bacterial infection were significantly changed. In bacterial culture, 22 strains of bacteria were detected, Escherichia coli accounted for 54.55% (12/22), were almost sensitive to cefepime, and all sensitive to imipenem and meropenem; Enterococcus following accounted for 22.73% (5/22), could be more sensitive to vancomycin, linezolid, teicoplanin. Conclusion Urinary tract infection is common in under 3 years old babies. Patients aging under 6 months are more likely to be complicated with severe sepsis and septic shock. Therefore, we should be especially vigilant of the UTI among the babies whose first manifestations appear to be sepsis only. It is important to find out the site of infection as early as possible, in order to prevent misdiagnosis. It is also critical to use broad-spectrum antimicrobial therapy within 1 hour when severe sepsis is diagnosed in order to reduce the mortality of sepsis in infants and improve the prognosis.
