A case report of primary extubation by partial cricotracheal resection for severe subglottic stenosis / 临床耳鼻咽喉头颈外科杂志

This patient suffered from severe subglottic stenosis(grade Ⅳb). During partial cricotracheal resection, we cut through the cricothyroid membrane and the cricoid arch along the line from the lower edge of the thyroid cartilage to 5 mm of the inferior thyroid cartilage corner anteromedially. This can protect the cricothyroid joint, effectively protect the recurrent laryngeal nerve, and also support the airway. Strictly adhere to airway separation, avoid excessive separation of scars, and combine with reasonable postoperative management to achieve a safe extubation.

The analysis of risk factors for cerebral microbleeds in cerebral infarction patients / 中国神经精神疾病杂志

Objective To analyze the risk factors of cerebral microbleeds (CMBs) in acute cerebral infarction patients. Methods We consecutively included 255 acute cerebral infarction patients who were admitted in Neurology Department of the First Affiliated Hospital of Fujian Medical University from January 2014 to December 2016. According to the number and location of CMBs, the patients were divided into infratentorial, cortical and deep cerebral groups, each of which included non-mild and moderate-severe subgroups. The differences of the level of glomerular filtration rate (eGFR) and some common arteriosclerotic risk factors were analyzed between subgroups, and the multiple logistic regression analysis was performed. Results A total of 140 subjects (54.9%) had CMBs. In the infratentorial group, the proportion of patients who were with low eGFR level in the moderate-severe CMBs subgroup was higher than in the non-mild CMBs subgroup (P=0.024). The low eGFR level (OR=3.874, 95% CI:1.261～11.901, P=0.018) and the long duration of hypertension (OR=2.128, 95%CI: 1.004～4.510, P=0.018) were the independent risk factors of the moderate-severe infratentorial CMBs. Conclusion The low eGFR level and long duration of hypertension are risk factors for the moderate and severe infratentorial CMBs after acute ischemic stroke.
