RESUMO
Objective:To describe the characteristics and analyze risk factors for surgical items count near-miss errors stemming from the self-incident reports of staff nurses from operating room, to reduce the risk of counting surgical items and prevent the occurrence of the relative adverse events.Methods:This was a retrospective study. Used the self-made checklist to retrospect the surgical items count errors, relative characteristics and reasons from the operating room nurses of Department of Anesthesiology, Shandong Provincial Hospital Affiliated to Shandong First Medical University reported from January 2017 to December 2021. Grey Relational Analysis was used to analyze and identify the risk elements.Results:A total of 98 surgical items count near-miss errors were reported by nurses.The unclear items were mainly classified into 6 categories, of which 52.04% (51/98) were disposable surgical items, 24.49% (24/98) were fine parts of surgical instruments, 14.28% (14/98) were implants, 5.10% (5/98) were electrosurgical instruments, 3.06% (3/98) were power systems, and 1.02% (1/98) were medical lasers; the disposable surgical items were the highest risk of surgical items count near-miss errors (non-standard behaviors of surgeons ξ 1=0.333); among the 9 risk factors, non-standard behaviors of surgeons ( r1 = 0.673), instrument nurses improper operation ( r4 = 0.691) and surgeons errors ( r2 = 0.693) were the most important influence factors. Conclusions:Analyzing the possible system risk factors resulting from the near-miss error could be a useful method for nurses to generate hierarchical risk-control strategies and improve surgical items count safety for patients. This com prerent the occurrence of adverse events.
RESUMO
Objective To study the effect of left ventricular function in the left anterior descending coronary artery stent implantation.Methods randomly 100 cases of left anterior descending coronary artery stenosis in patients with coronary heart disease branch were divided into the observation group and the control group (each group 50 cases),the control group used mainly drug treatment,the observation group used a implanted stent in the treatment of percutaneous left anterior descending coronary artery.the left ventricular end diastolic diameter(LVEDD),left ventricular end systolic diameter(LVESD,left ventricular ejection fraction(LVEF) and serum N terminal pro-brain natriuretic peptide(NT-proBNP) levels were observed between two groups.Results after treatment,6 months,two groups of LVEDD,LVESD and NT-proBNP compared with those before treatment were significantly lower(t =2.75,3.14,3.54,all P ＜0.05),while LVEF increased significantly (t =12.45,P ＜ 0.05);and compared with the control group,LVEDD,LVESD of the observation group decreased significantly,LVEF increased significantly(t =2.27,3.75,2.21,all P ＜ 0.05).Conclusion The left anterior descending coronary artery stent implantation in treatment can effectively improve left ventricular function in patients with coronary heart disease.
