ABSTRACT
OBJECTIVE To investigate the effects of esketamine for multimodal analgesia on opioid consumption and gastric motility in mechanically ventilated non-surgical intensive care unit (ICU) patients. METHODS Forty cases of mechanically ventilated non-surgical patients in the ICU of our hospital from February 1st, 2023 to July 31st, 2023 were selected and randomly divided into control group and esketamine (S-K) group using grouping method with opaque envelopes, with 20 cases in each group. Control group was given sufentanil, and S-K group was infused with Esketamine hydrochloride injection at a constant rate of 0.2 mg/(kg·h)+ sufentanil. The treatment period length, analgesic compliance rate, sedation level, analgesic and sedative consumption, and gastric motility indexes were compared between the two groups. RESULTS There was no statistically significant difference in the treatment period length, analgesic compliance rate, sedation level, or the consumption of propofol and midazolam between the two groups (P>0.05). The consumption of sufentanil in the S-K group was significantly less than control group (P< 0.05). Compared with 1 h after randomization, the antral contraction frequency, antral contraction amplitude and antral motility index of patients in the S-K group were significantly higher at 72 h after randomization and were significantly higher than control group (P<0.05). CONCLUSIONS Esketamine may reduce opioid consumption and improve gastric motility in mechanically ventilated non-surgical ICU patients while ensuring a level of analgesic sedation.
ABSTRACT
Intra-abdominal infection is the second common infectious disease in intensive care unit and inhospital patients, with the mortality rate of 20%-30%. Advances in medicine have not improved the outcomes of patients with intra-abdominal infection, and the increasing multi-drug resistance organism may lead to a deterioration in the prognosis of patients with intra-abdominal infection. Gut microbiota dysbiosis and abdominal cavity infections show an interdependent and mutually aggravating relationship. Intestinal microecological preparations regulate gut flora and are potential therapeutic measures for intra-abdominal infections. The authors review the changes in gut flora during intra-abdominal infection, the effect of gut flora on the prognosis of intra-abdominal infections and the role of intestinal microecological preparations in intra-abdominal infections.
ABSTRACT
Objective:To investigate the clinical characteristics and influencing factors of mortality in patients with intra-abdominal candidiasis (IAC).Methods:The retrospective case-control study was conducted. The clinicopathological data of 203 IAC patients who were admitted to 7 medical centers from June 2018 to June 2020 were collected, including 54 cases in Sir Run Run Shaw Hospital of Zhejiang University School of Medicine, 31 cases in Fujian Medical University Union Hospital, 25 cases in Beijing Hospital, 25 cases in the First Affiliated Hospital of Xi'an Jiaotong University, 24 cases in China-Japan Friendship Hospital, 22 cases in General Hospital of Eastern Theater Command of Chinese PLA and 22 cases in Chongqing University Cancer Hospital. There were 130 males and 73 females, aged (64±15)years. Observation indicators: (1) candida infection and treatment of IAC patients; (2) analysis of influencing factors for mortality of IAC patients. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was analyzed using the t test. Measurement data with skewed distribution were represented as M(range), and comparison between groups was analyzed using the Mann-Whitney U test. Count data were expressed as absolute numbers or percentages, and comparison between groups was analyzed using the chi-square test. Univariate and multivariate analyses were performed by Logistic regression model. Results:(1) Candida infection and treatment of IAC patients: 134 cases of candida albicans were cultured in the initial abdominal drainage fluid or intraoperative abdominal specimens of 203 patients, and 49 cases were treated with fluconazole. Of 69 cases infected with non candida albicans, 13 cases were treated with fluconazole. The resistance rate of candida albicans to fluconazole was 5.91%(12/203). Of 203 patients, there were 68 cases with infections shock, 53 cases with renal failure, 84 cases with respiratory failure and 63 cases with multiple organ failure, respectively. There were 148 of 203 patients admitted to intensive care unit for 9 days(range, 3-20 days), and the total hospital stay was 28 days(range, 17-50 days). Of 203 patients, 86 cases were cured and discharged, 50 cases were improved and transferred to local hospitals, 32 cases gave up treatment and discharged automatically, 19 cases died, 16 cases had no follow-up data. The mortality was 25.12%(51/203). (2) Analysis of influencing factors for mortality of IAC patients. Results of univariate analysis showed that acute physiology and chronic health evaluation score, sequential organ failure assessment score, the Cr, bilirubin, albumin, procalcitonin, and PLT on the first day of candida positive culture, of the lowest value in a week and the highest in a week, heart disease, diabetes, infections shock, renal failure, respiratory failure, multiple organ failure, anti-fungal therapy were the related factors for mortality of IAC patients ( t=-2.322, Z=-2.550, -2.262, -4.361, t=2.085, Z=-3.734, -5.226, -2.394, -5.542, t=3.462, Z=-4.957, -5.632, 3.670, -5.805, t=3.966, Z=-3.734, -5.727, χ2=4.071, 4.638, 27.353, 18.818, 13.199, 26.251, 13.388, P<0.05). Multivariate analysis showed that the bilirubin, procalcitonin on the first day of candida positive culture and infections shock were independent risk factors for mortality of IAC patients ( odds ratio=1.021, 1.022, 6.864, 95% confidence interval as 1.010-1.033, 1.001-1.044, 1.858-25.353, P<0.05). Conclusions:The common fungus of IAC was candida albicans, and fluconazole can be used as the initial empirical treatment. The prognosis of patients with abdominal candidiasis is poor. Bilirubin, procalcitonin on the first day of candida positive culture and infections shock are indepen-dent risk factors for mortality of IAC patients.

ABSTRACT
Objective To discuss the clinical value of Dimethicone power applied under endoscopy in examination of upper gastrointestinal tract. Methods 800 patients who received common endoscopy examination from Nov. 2014 to Nov. 2015 were recruited into the study and randomly divided into two groups: experimental group and control group. Fifteen minutes before the examination, the experimental group took Dimethicone power 5 g and 30 ml pure water. At the same time, the control group took 30 ml pure water only. According to the clarity of the endoscopic field of vision, the examination results were classified into 4 levels (A, B, C, D), and the inspect time of each patient was recorded. Results In experimental group, endoscopic vision was significantly higher than control group ( <0.05), and the inspect time was significantly shorter than control group ( < 0.05). Conclusion Dimethicone power can significantly improve the clarity of the endoscopic field of vision and alleviate the suffering of patients with short-er inspect time, which can be used as an adjuvant before routine endoscopy examination.
