Lactulose vs Polyethylene Glycol for Bowel Preparation: A Single-Center, Prospective, Randomized Controlled Study Based on BMI.

INTRODUCTION: Colonoscopy is currently considered as one of the principal techniques to diagnose the colorectal diseases. Admittedly, qualified bowel preparation before colonoscopy is a premise for high-quality examination. Lower quality bowel preparation might seriously impede visualization of the intestinal mucosa, resulting in missed and misdiagnosed intestinal lesions. Therefore, it is necessary to choose the appropriate oral laxative based on the guarantee of safety and efficacy. METHODS: This prospective randomized controlled study was conducted to compare lactulose oral solution and polyethylene glycol (PEG) electrolyte powder for bowel preparation using the following indicators: Boston Bowel Preparation Scale, Bowel Bubble Score, detection rate of adenoma and lesion, patients' satisfaction, and adverse effects. Our study investigated the suitability of 2 bowel preparation reagents for patients with different body mass indices mainly based on body mass index (BMI). RESULTS: In the lactulose group, there was a significant improvement in the quality of bowel preparation compared with those in the PEG group ( P < 0.05), especially in people with normal BMI and higher BMI. Compared with the PEG group, individuals in the lactulose group had a significantly higher adenoma detection rate (50% vs 33.5%, P < 0.05) and taste scores (8.82 vs 6.69, P < 0.05), as well as significantly fewer adverse reactions (6.5% vs 32.5%, P < 0.05). DISCUSSION: Lactulose oral solution is superior to PEG in bowel preparation quality and taste, especially in normal BMI and higher BMI groups. It can be used clinically as a potential and promising bowel preparation agent in the future. Clinical Trial registration number: ChiCTR2100054318.

Study on the application and effect of adjustable mirabilite external vest in severe acute pancreatitis / 中国实用护理杂志

Objective:To investigate the clinical effect of homemade adjustable mirabilite vest in patients with severe acute pancreatitis and supply reference for clinical nursing.Methods:This was a randomized controlled study. One hundred patients with acute severe pancreatitis admitted to Putuo Hospital, Shanghai University of Traditional Chinese Medicine from January 2021 to June 2022 were selected, and were divided into the pocket group and the vest group according to the order of admission with 50 cases in each group. The pocket group used traditional mirabilite bag for external application, the vest group used adjustable mirabilite vest for external application. The other treatment measures were the same for both two group. The comfort degree, itching severity and average length of hospital stay of these two groups were compared.Results:The basic data of the two groups were homogeneous. The difference were not statistically significant( P>0.05). After intervention, the comfort degree of the pocket group was (65.90 ± 7.95) points while the comfort degree of the vest group was (77.04 ± 5.96) points. The difference was statistically significant ( t = 7.93, P<0.01). The degree of pruritus was (12.72 ± 3.95) points in the pocket group and (8.00 ± 1.20) points in the vest group.The difference was statistically significant ( t = 8.08, P<0.05). The mean length of hospital stay in the pocket group was (15.86 ± 5.83) days and (11.02 ± 3.38) days in the vest group. The difference was statistically significant ( t = 5.08, P<0.01). Conclusions:When using topical mirabilite for patients with acute severe pancreatitis, the use of adjustable mirabilite vest can significantly improve patients′ comfort, reduce itching, and reduce the number of hospital days, which has the value of promotion and use.
