Objective To explore the application effect of PDCA cycle model in the teaching of operational error for nursing students in the overall teaching .Methods One hundred and fifty-three nursing students from June 2011 to May 2012 were chosen as the control group , and received the conventional teaching . One hundred and fifty-nine nursing students from June 2012 to May 2013 were chosen as the study group , and received the PDCA cycle model of teaching . The scores of performance assessment of operation in the departments and department of nursing were collected , and the questionnaire on the operational error during the practice was used , and the data were analyzed .Results The scores of operation assessment of nursing in the departments and department were respectively (82.64 ±2.37), (73.06 ±3.04) in the control group, and were lower than (83.67 ±3.44), (74.53 ±3.52) in the study group, and the differences were statistically significant (t=-3.368 4,-3.941 3, respectively;P<0.05).The rate of nursing error was 40.5% in the control group, and was higher than 28.9% in the study group, and the difference was statistically significant (χ2 =4.6292,P<0.05).No difference was found in the time of the occurrence of nursing error between two groups (P>0.05).The nursing error occurred mainly in the early practice , and rarely at the end of practice. Conclusions Application of the PDCA cycle model in the teaching of operational error for nursing students in clinical teaching is effective and feasible , and the guidance of the nursing ’ s teaching through the scientific management concept is helpful to reduce the error rate of clinical operation and improve the system of teaching management .

Objective Using the evaluation and analysis of nursing risk of the patients with gastric tube after open-heart surgery , to formulate corresponding nursing strategies in order to insure patients'safety. Methods A total of 316 patients with gastric tube after open heart surgery were examined and evaluated by each nursing risks.Results A total of 316 patients with gastric tube had no adverse events , with good nursing outcomes.Conclusions By evaluation and analysis the nursing risk of the patients with gastric tube after open-heart surgery, it is possible to reduce and avoid harmful events and insure patients'safety.

Objective To summarize the nursing management of 125 I radioactive seed in the treatment of spinal metastases .Methods Fourteen patients with 125 I radioactive seed in the treatment of spinal metastases received the nursing intervention including psychological care , observation of disease after surgery , protection from radiation and nursing of complications .Results Nine patients received the percutaneous kyphoplasty combined with 125 I radioactive seed , and 5 patients received the dissection of tumors , laminectomy decompression , pedicle screw fixation and 125 I radioactive seed implantation .The displacement of particles and radioactive spinal cord inflammation were found in all patients .The cases of death were 0 cases during perioperative period .The volume of tumor was significantly reduced in 13 patients through the observation of CT, and was no changes in one patient .Conclusions 125 I radioactive seed in the treatment of spinal metastases is a new way to treat the tumor , and nursing intervention plays important roles of controlling the disease , improving the quality of life and prognosis of patients .
