From August 2006 to June 2011 among consecutive 18 294 patients underwent thoracic surgery from Shanghai Chest Hospital,41 developed adverse events during peri-anesthesia period and the incidence was 0.224%,and the constituent ratios of the predictable and unpredictable events were 15% and 85%,respectively.Cardiac arrest and massive hemorrhage were the main clinical manifestation of the adverse events and the constituent ratios were 37% and 24%,respectively.Among the inducements for adverse events,patient's factor,surgical factor,anesthesia factor,patient-surgery factor,patient-anesthesia factor and patient-surgery-anesthesia factor accounted for 12.2%,48.8%,12.2%,7.3%,7.3% and 12.2%,respectively.The ratio of death from adverse events was 17% (7 cases),and among the inducements for adverse events causing death,surgical factor,patient-surgery factor and patient-surgery-anesthesia factor accounted for 43%,43% and 14%,respectively.The incidence of adverse events was 1.093% in the patients underwent operation on trachea,which was significantly higher than that in the patients underwent operation on lung (0.223%),mediastinum (0.236%) and esophagus (0.194%).In conclusion,although the adverse events which occurred during peri-anesthesia period in the patients underwent thoracic surgery were rare,they threatened the safety of patients.Surgical factor was not only the main inducement,but also the risk factor for death,and cardiac arrest and massive hemorrhage were the main clinical manifestation of the surgery-related adverse events.For cardiac arrest,as long as it was found in time and treated appropriately,the serious consequences could be avoided.For massive hemorrhage,more attention should be paid due to be the main reason of death,and the prevention depended on the surgeon's improvement of diagnosis and surgery.It was difficult to predict patient-related the adverse events and careful monitoring was required.For the anesthesia-related adverse events,they were mostly due to the poor airway management,so preoperative airway assessment should be strengthened.

Objective To evaluate the feasibility, safety and effectiveness of interventional occlusion with thin waist occluder for perimembranous ventricular septal defect with pseudoaneurysm. Methods During the period from March 2008 to March 2013 at Shanghai Yodak Cardiothoracic Hospital , interventional occlusion with thin waist occluder was carried out in a total of 96 patients with perimembranous ventricular septal defect (VSD) complicated by pseudoaneurysm. The patient’s age varied from 2 years to 36 years. Before the procedure, routine left ventricular angiography and ascending aortic angiography were carried out. Left ventricular angiography and ascending aortic angiography as well as the transthoracic ultrasonography were performed immediately after the procedure to observe the therapeutic results. Follow-up checkups with transthoracic ultrasonography, EKG and chest X-ray film were conducted at one week as well as at one, 3, 6 and 9 months after the surgery were conducted. Results Successful occlusion of VSD was obtained in 93 patients, with a success rate of 96.8% (93/96). After the surgery, small amount of shunt flow was detected in 8 patients, which disappeared within 48 hours in 7 patients, and in the other one the shunt flow disappeared one month later which was confirmed by follow-up examination. After the treatment, complete right bundle branch block occurred in 4 patients, complete left bundle branch block in 5 patients, and transientⅢdegree atrioventricular block in one patient. The conduction block disappeared at the time of discharge in all patients. The left ventricular end-diastolic diameter (LVEDD) decreased from preoperative (47.5 ± 5.2) mm to postoperative (45.2 ± 5.1) mm, the difference was statistically significant (t = 18.33, P < 0.01). During the follow-up period lasting for 9 months, no delayed cardiac arrhythmia, valve damage or sudden death occurred. Conclusion For the treatment of perimembranous ventricular septal defect with pseudoaneurysm, interventional occlusion with thin waist occluder is safe and effective with excellent mid-term effect. Based on the imaging findings, including the location, shape, ruptured orifice, number of the perimembranous pseudoaneurysm as well as the distance between the pseudoaneurysm and the aortic valve, to select suitable occluder and proper occlusion site is the key to ensure a successful surgery.

This study was aimed to investigate the blood-enriching effect of processed Radix Polygoni Multiflori on blood deficiency rats. A total of 140 SD rats were randomly divided into 14 groups, which were the blank control group, blood deficiency model group, positive control group and 11 test groups. The blank control group and model control group were treated with distilled water and the positive control group was given X ue b ao Buxue soluble granules. The test groups were treated with 11 different kinds of processed Radix Polygoni Multiflori sam-ples at a dosage of 2 g?kg-1 respectively. All rats were given drugs once a day. After 10 days, blood samples were collected and the amount of red blood cell (RBC), hemoglobin (Hb), haematocrit (HCT), whole blood viscos-ity and plasma viscosity, prothrombin time were estimated. The results showed that 9 processed Radix Polygoni Multiflori groups can increase the number of RBC and Hb significantly ( P < 0 . 05 or P < 0 . 01 ) in blood deficien-cy rat models. They were the sample processed with decoction of black soybean (DBS) for 24 h, with wine and DBS combination for 24 h , steamed for 4 h and 8 h under high pressure , with DBS for 6 h and 8 h , with wine for 6 h, with wine and DBS combination under high pressure, respectively. The samples processed with DBS un-der high pressure for 8 h increased RBC and Hb were more obviously ( P < 0 . 01 ) . The 8 groups can improve the situation of functional disorder of blood rheology significantly ( P < 0 . 05 or P < 0 . 01 ) . They were the unprocessed samples, processed with DBS and wine for 24 h respectively, with DBS and wine combination for 24 h, steamed for 4 h and 8 h or steamed with DBS for 6 h and 8 h or with wine for 6 h under high pressure respectively. It was concluded that the blood-enriching effect was improved while the R adix Polygoni Multiflori was processed with DBS or wine and under high pressure for 6-8 h .
