  • Risk Factors for Prolonged Mechanical Ventilation in Post-thymectomy Myasthenic Crisis

    ObjectiveTo analyze the risk factors for post-thymectomy myasthenic crisis (PTMC) and prolonged mechanical ventilation, in myasthenia gravis patients who underwent extended thymectomy. MethodsWe retrospectively analyzed the clinical data of 79 patients including 38 males and 41 females who experienced PTMC and required mechanical ventilation in Daping Hospital between June 2008 and November 2014. Single factor analysis and multivariate analysis were conducted. ResultsMorbidity of PTMC was 20.6% (79/384). Result of single-factor analysis showed that postoperative pneumonia was one of the main reasons of prolonged mechanical ventilation (P < 0.05). Result of multiple-factor analysis showed that the operation time was positively correlated with mechanical ventilation time (P < 0.05). The risk factor of prolonged mechanical ventilation time in PTMC was not associated with sex, age, disease history, myasthenic crisis history, Osserman classification, dosage of pyridostigmine before and after the operation, surgical approach, bleeding volume, other therapies besides mechanical ventilation (P > 0.05). ConclusionMechanical ventilation is one the main therapy of PTMC, operation time, and postoperative pneumonia are the main factors to prolong mechanical ventilation time. In order to decrease morbidity of PTMC and shorten mechanical ventilation time, the operation time should be controlled and pulmonary infection should be avoided.

  • Character of Solitary Pulmonary Nodules:Analysis of Risk Factors and Surgical Treatment

    ObjectiveTo summarize the experience of diagnosis and surgical treatment for solitary pulmonary nodules (SPN). MethodsWe retrospectively analyzed clinical data of 327 patients with video-assisted thoracoscopic surgery (VATS) lung resections and subsequent pathological diagnosis of the SPNs in Daping Hospital from January 2008 through May 2014 year. There were 183 males, 144 females at age of 56.6(20-79) years. ResultsOne way analysis of variance showed that there were significant differences in age, smoking index, diameter, glitches, lobulation, traction of pleural, cavity, vascular convergence, calcification between benign and malignant lesions (P<0.05). Logistic regression analysis revealed that age (P=0.004, OR=1.084), diameter (P<0.001, OR=1.467), glitches (P=0.001, OR=8.754), lobulation (P<0.001, OR=10.424), traction of pleural (P=0.002, OR=6.619) were independent predictors of malignancy in patients with SPN. Operation time was 121.4±47.6 min. Blood loss was 105.3±57.8 ml. Postoperative hospital stay was 7.3±2.4 days. Diagnostic accuracy was 99.7%. Incidence of complication was 0.5%. Five (1.5%) patients were converted to thoracotomy and no perioperative death occurred. ConclusionsAge, diameter, glitches, lobulation, traction of pleural are independent predictors of malignancy in the patients with SPN. VATS is a safe and efficient method for diagnosis and treatment of SPN.
