【摘要】 目的 探讨微创经皮肾镜碎石术后并发感染性休克的原因和防治措施。 方法 回顾性分析2005年1月-2010年12月5例经皮肾镜术300例，其中术后并发感染性休克5例的临床资料。男1例，女4例，均表现为术后2~8 h内出现寒战、高热、烦燥不安，血压降至80/50 mm Hg（1 mm Hg=0.133 kPa）以下，心率超过120次/min。所有患者均行抗感染和抗休克治疗。 结果 所有患者均在72 h内停用升压药，1周内体温及血常规恢复正常，术后15 d治愈出院。 结论 感染性休克是微创经皮肾镜碎石术严重的并发症之一，术前有效抗感染、术中低压灌注、术后加强生命体征的监测、早期发现并合理处理，可有效防治感染性休克的发生。【Abstract】 Objective To explore the etiology and treatment of septic shock after percutaneous nephrolithotomy. Methods From Janurary 2005 to December 2010, the clinical data of five patients with septic shock after percutaneous nephrolithotomy in our hospital were retrospectively analyzed. The patients, including one male and four females, had chillness and high temperature after the nephrolithotomy. The blood pressure decreased to under 80/50 mm Hg （1 mm Hg=0.133 kPa）, and the heart rate was more than 120 per minute. All patients underwent anti-shock and anti-infection therapies rapidly. Results Five patients were cured in the end, their temperature and blood routine tests returned to normal within one week. Conclusions Septic shock is one of the serious complications after percutaneous nephrolithotomy. Effective preoperative preparation, low pressure irrigation during operation, early diagnosis and treatment postoperatively are the effective ways to prevent the septic shock.
Objective To formulate an evidence-based treatment plan for a patient with suspected pyogenic liver abscess. Methods Based on the clinical questions raised by a patient with suspected pyogenic liver abscess, we searched The Cochrane Library (Issue 4, 2007), MEDLINE (1996 to January 2008), ACP Journal Club (1991 to January 2008), and Chinese Journal Full-text Database (1994 to January 2008) for systematic reviews, randomized controlled trials (RCTs) and case-control studies. The quality of the included studies was assessed. Results We did not find any systematic reviews or large-scale RCTs involving a comparison between laparoscopic drainage and surgical drainage in the treatment of pyogenic liver abscess. Four clinical retrospective studies closely related to our questions were found and assessed. These studies concluded that laparoscopic drainage for liver abscesses was a safe alternative for patients requiring surgical drainage. Based on the current evidence, as well as our clinical expertise and the patient’s values, laparoscopic drainage was not used for this patient and surgical drainage was applied. The patient was recovered and discharged. Conclusion Current evidence showed that laparoscopic drainage might be effective and safe for liver abscesses but high-quality large-scale randomized controlled trials are still required.
Objective To investigate the prevalence and risk factors of degenerative disc disease (DDD) in pilots. Methods From January 2021 to May 2022, pilots were surveyed using a whole group sampling method and relevant imaging data were collected. The contents of the survey included basic information, DDD-related information, flight-related information, and personal habits. The prevalence of DDD was calculated, and univariate χ2 test, t-test, and multivariate logistic regression analysis were performed for the diseased and healthy groups to screen the risk factors of DDD. Results A total of 170 copies of questionnaire were sent out and 162 valid copies were returned. The prevalence of DDD was 47.5% (77/162), including 27.8% (45/162) for cervical spondylosis, 29.6% (48/162) for lumbar disc herniation, and 3.1% (5/162) for degenerative lumbar spondylolisthesis. The results of univariate analysis showed that body mass index (t=2.594, P=0.010), driving age (t=2.160, P=0.032), maximum load in flight (t=2.953, P=0.004), mean load in flight (t=2.575, P=0.011), insomnia (χ2=4.756, P=0.029) and smoking (χ2=7.977, P=0.005) were significantly different between the diseased group and the healthy group. Multivariate logistic regression showed that driving age [odds ratio (OR)=1.077, 95% confidence interval (CI) (1.025, 1.132), P=0.004], maximum load in flight [OR=1.279, 95%CI (1.109, 1.475), P=0.001], helmet weight [OR=1.516, 95%CI (1.056, 2.175), P=0.024], insomnia [OR=2.235, 95%CI (1.114, 4.483), P=0.024], and smoking [OR=2.527, 95%CI (1.255, 5.087), P=0.009] were risk factors for DDD. Conclusions The prevalence of DDD is high in pilots. High driving age, high maximum load in flight, high helmet weight, insomnia, and smoking may be independent risk factors for DDD.
