The Effects of Nursing Risk Intervention on Drainage Safety after Prostatic Hyperplasia Surgery

Objective:To explore the effect of nursing risk intervention on drainage safety after prostatic hyperplasia surgery.Methods:80 patients who underwent prostatic hyperplasia surgery in our hospital(People’s Hospital of Jiangsu Province)from August 2020 to August 2021 were randomly divided into group A and group B.Patients in group A were treated with routine postoperative drainage nursing intervention,and patients in group B were given nursing risk intervention based on group A,and the intervention results of the two groups were compared.Results:Comparison of patient satisfaction:the patient satisfaction in group B(97.50%)was higher than that in group A(25.00%).Comparison of drainage tube accidents:the accident rate of group B was lower than that of group A;Comparison of patients’psychological anxiety:the psychological anxiety of patients in group B after nursing intervention was lower than that in group A.Comparison of patients’quality of life:the quality of life of patients in group B after nursing intervention was higher than that in group A.The difference was statistically significant(P<0.05).Conclusion:Clinical nursing risk intervention after prostatic hyperplasia surgery can greatly improve the safety of drainage,reduce patients’psychological anxiety and improve patients’quality of life after treatment.It has the value of clinical application and promotion.

Numerical comparison of coal spontaneous combustion danger influenced by different methane drainage patterns in gob area

The influence of gas drainage on float coal spontaneous combustion in the work face with ＂U＂ style ventilation was studied. Numerical simulation was used to compare the mutative law of steady flow and density field in the gob area under different drainage conditions by solving the equation set, including mass, momentum, and component transition. Consequently, the sequence of drainage effect and safety was obtained. The result manifests that the more effective the drainage pattern is, the easier float coal spontaneous combustion is caused due to air being guided into the depth of the gob area when the drainage position is arranged in the gas accumulation area. If the widened scope of oxidation zone exceeds the upper limit of the work face advancing speed, nitrogen injection should be applied to decrease the probability of spontaneous combustion. Then, the pipe laying drainage in the upper angle is most economical and safe compared with other drainage patterns when only the situation of gas accumulation is controlled in the upper angle. Finally, drainage pressure must not be too great. Otherwise the drainage density will decrease even if hazard is caused by back flow possibly happening in the return outlet when the drainage position is arranged near the work face.
