ABSTRACT
Objective:To investigate the effect of paper towel combined with 360° horizontal turning over method on the field of vision, operation time and detection of small lesions before gastroscopy, so as to improve the detection rate of early gastrointestinal cancer.Methods:The outpatients and inpatients who voluntarily accepted gastroscopy in the First Affiliated Hospital of Shandong First Medical University from May to October 2020 were enrolled. A prospective randomized controlled study was used. They were divided into the experimental group (paper towel group combined with 360° horizontal turning over) and the control group (routine) according to the random number table. Finally, a total of 948 patients were included, including 487 cases in the experimental group and 461 cases in the control group. The visual field clarity, operation time, rinse times, detection of micro lesions and detection of early cancer of the two groups were compared.Results:The scores of gastric mucosa clarity (fundus, body, antrum and whole stomach) in experimental group were (1.61 ± 0.79), (1.18 ± 0.56), (1.01 ± 0.36), (3.20 ± 0.51) points, which were significantly lower than (2.56 ± 0.82), (2.01 ± 0.65), (1.98 ± 1.10), (5.05 ± 0.89) points in control group. The difference was statistically significant ( t values were 0.02-0.07, all P<0.05). The operation time of the experimental group was (5.91 ± 0.41) min, which was significantly shorter than (6.80 ± 0.72) min of the control group, and the difference was statistically significant ( t=-7.46, P<0.05). The number of flushing in the experimental group was 67 times, accounting for 13.8%, which was significantly lower than 144 times in the control group, accounting for 31.2%, and the difference was statistically significant ( χ2=54.78, P<0.05). The number of microlesions in the experimental group was 398 cases, which was higher than 245 cases in the control group. The difference was statistically significant ( χ2=8.43, P<0.05). For biopsy pathology, the detection of precancerous lesions or early carcinomas in the experimental group (56 cases) was significantly higher than that in the control group (24 cases), and the difference was statistically significant ( χ2=6.45, P<0.05). Conclusions:The application of paper towel combined with 360° horizontal turning over method before gastroscopy can significantly improve the clarity of gastroscope field of vision, shorten the operation time, increase the detection rate of small lesions, and effectively improve the detection rate of early gastrointestinal cancer, which is a simple and practical preoperative preparation method.
ABSTRACT
Objective To design a new mattress according to clinical requirement and to observe its effect of reducing the time of changing sheets, weighing, saving nursing time of artificial posture and decreasing the extent of the drop in the temperature of the baby incubator. Methods Functional requirements and parameters of new-type mattress were designed through searching and summing up a large number of literatures concerned. The standard premature infant models weighing 1500 g were selected as the experimental object. 180 cases in the experimental group were placed in the insulation incubators of the new-type mattress, and 180 cases in the control group were placed in incubators with ordinary mattresses. Results The new-type mattress has the function of designing the shape of bird's nest, changing posture automatically and monitoring physique in real time. Volume data and equipped with skull-sensing headphones. Simulation experiment displayed that the time of changing sheets between the new mattress and the ordinary mattress was (4.04 ± 0.41) s and (18.07 ± 2.54) s, and the weighing time was 1.00 s and (37.93 ± 5.19) s. The daily nursing time of artificial posture was 0.00s and (5.40 ± 0.48) s and (0.08 ± 0.23)℃and (2.08 ± 0.57)℃. The difference was statistically significant(t=-151.74-45.36, P<0.05). Conclusion The new mattress can reduce the time of weighing weight and changing sheets, save the nursing time of artificial posture and decrease the extent of the drop in the temperature of the baby incubator .
