Qualitative study of poor intestinal preparation compliance before colonoscopy in elderly patients

Objective:To explore the influencing factors and psychological experience of poor compliance in intestinal preparation before colonoscopy in elderly patients,so as to provide more comprehensive reference for the implementation of targeted nursing intervention measures in the future and to improve the quality of intestinal preparation before colonoscopy in elderly patients.Method:According to the phenomenological research method in the qualitative research,a purposeful sampling selected 11 nursing staff from a digestive endoscopy center of a comprehensive tertiary Class A hospital in Shanxi Province as a research object for a semi-structured interview.Convenience Sampling selected semi-structured interviews with 13 elderly patients who underwent colonoscopy in a comprehensive tertiary Class A hospital in Shanxi Province from July to September 2018 for colonoscopy but had poor bowel preparation results.Colaizzi Phenomenological research methods conduct inductive analysis of data.Results:Through semi-structured interview,the influencing factors of poor compliance of intestinal preparation before colonoscopy in elderly patients were summarized as follows:①nursing staff ignored the individualized education of patients;②in the process of intestinal preparation,elderly patients have insufficient understanding of intestinal preparation,insufficient attention,forgetting the contents of intestinal preparation,intolerance in the process of intestinal preparation,lack of encouragement and professional guidance,etc.Conclusion:In clinical practice,medical staff should strengthen the individualized education of patients undergoing colonoscopy,guide them to correctly understand the intestinal preparation process and understand the importance of intestinal preparation,actively explore more convenient intestinal preparation methods,and actively play the positive role of family members in intestinal preparation of elderly patients.

Chemoselective Synthesis of Novel Heterocyclic [3.3.3]Pro- pellane Derivatives via a One-pot Three-component Reaction

A highly chemoselective method for the synthesis of heterocyclic [3.3.3]propellane derivatives was developed via sequential three-component reactions of acenaphthenequinone, malononitrile/cyanoacetate and a variety of 1,3-dicarbonyl compounds under mild conditions in ethanol. A plausible mechanism for this type of reaction was proposed. The value of this method was highlighted by its high selectivity, simple procedures, and good yields.
