Methods: a total of 110 patients undergoing colonoscopy and nursing in our hospital were randomly selected. The earliest time to receive examination and treatment was January 2020, and the latest time to receive examination and treatment was December 2020. All were divided by computer into two groups, called control and intervention groups. Patients in the control group need to carry out general quality care with the plan formulated by our hospital, and patients in the intervention group need to carry out the related contents of quality control circle activities for intervention. After nursing the patients in the two groups, the success of colonoscopy in the two groups should be counted, and the satisfaction of the patients in the two groups should be compared and analyzed. Results: after the intervention of different nursing methods, the difference of the above observation indexes was obvious. The success rate of colonoscopy in the intervention group was better than that in the control group (P < 0.05), and the satisfaction of nursing in the intervention group was also better than that in the control group (P < 0.05). Conclusion: in the process of patient care, the reasonable use of quality control circle activities can effectively improve the efficiency and quality of cooperation in the hospital, and then improve the success rate of examination and the satisfaction of patients. Therefore, it can be reasonably promoted in combination with the actual situation in the hospital.展开更多

文摘Objective: combined with the clinical treatment problems of patients with orthodontic treatment, a new type of micro-implant anchorage was used in the treatment, and the application effect was analyzed. Methods: according to the requirements, suitable patients in our hospital were selected. There were 80 patients who met the standards. They received conventional treatment and micro-implant anchorage treatment respectively. The orthodontic status of the patients and the adverse reactions caused by the patient's body during the treatment in the hospital were studied. According to the clinical orthodontic indicators of the patients, the data of the two groups were compared in various aspects. Results: the orthodontic correction of the patients in the observation group achieved the expected effect after treatment. There were 39 cases without any problems, accounting for 97.50% of the population in this group, which was significantly higher than 80.00% in the control group. After effective treatment, 1 case had adverse reactions, accounting for 2.50% of the population in this group, which was not significantly less than 15.00% in the control group, and the difference was significant. After treatment, the molar displacement distance of the observation group was (3.31±0.32) mm, which was significantly smaller than that of the control group ( 5.21 ± 0.53 ) mm. ( 2.51±0.72 ) mm, the difference of incisor inclination in the observation group after treatment was ( 27.51±6.62 ) degrees, significantly larger than that in the control group ( 15.16±4.53 ) degrees, and the difference was significant (p<0.05). Conclusion: the use of micro-implant anchorage in clinical treatment of patients with orthodontic treatment has obvious advantages, which can help improve the oral deformity of patients, allow patients to have better treatment effects, and reduce the probability of adverse reactions, which is worthy of promotion.
文摘Objective: to explore the practical effect of the activities of the supply tube in the process of colonoscopy nursing. Methods: a total of 110 patients undergoing colonoscopy and nursing in our hospital were randomly selected. The earliest time to receive examination and treatment was January 2020, and the latest time to receive examination and treatment was December 2020. All were divided by computer into two groups, called control and intervention groups. Patients in the control group need to carry out general quality care with the plan formulated by our hospital, and patients in the intervention group need to carry out the related contents of quality control circle activities for intervention. After nursing the patients in the two groups, the success of colonoscopy in the two groups should be counted, and the satisfaction of the patients in the two groups should be compared and analyzed. Results: after the intervention of different nursing methods, the difference of the above observation indexes was obvious. The success rate of colonoscopy in the intervention group was better than that in the control group (P < 0.05), and the satisfaction of nursing in the intervention group was also better than that in the control group (P < 0.05). Conclusion: in the process of patient care, the reasonable use of quality control circle activities can effectively improve the efficiency and quality of cooperation in the hospital, and then improve the success rate of examination and the satisfaction of patients. Therefore, it can be reasonably promoted in combination with the actual situation in the hospital.
