Objective To establish an expert consensus on the management of mini-midline catheters(hereinafter referred to as the'consensus')to guide nurses in standardizing the insertion and maintenance of mini-midline catheters.Methods Evidence was systematically retrieved,scientifically evaluated,and synthesized using evidence-based methods to draft the initial version of the consensus.From December 2023 to July 2024,totally 2 rounds of expert correspondence and 2 rounds of expert panel discussions were conducted to revise the content,resulting in the final version.Results There were 17 experts from tertiary A general hospitals in Beijing,Shanghai,Hunan,Hubei,Sichuan,Jiangsu,Hainan,Guangxi Zhuang Autonomous Region,and Shandong participating in the consultation,with a 100％response rate.In the 2 rounds of expert correspondence,the authority coefficients were 0.947 and 0.962,respectively.The mean importance scores of all items exceeded 4.00 points.The coefficients of variation(CV)were 0-0.32(first round)and 0-0.15(second round).Kendall's concordance coefficients were 0.097 and 0.101(both P＜0.001).The consensus covers 11 sections,including definition,indications,contraindications,qualification training,pre-insertion preparation,catheter insertion,catheter use,catheter maintenance,catheter removal,prevention and management of common complications,and health education.Conclusion The Consensus demonstrates scientific rigor and comprehensively addresses key procedures before,during,and after the insertion of mini-midline catheters,providing actionable guidance for nurses in catheter insertion and maintenance.

Objective:To summarize the clinical experience in treating acute superior mesenteric artery embolization with intestinal necrosis.Methods:Clinical data, surgical methods, complications and 30-day follow-up of patients with acute superior mesenteric artery embolization and intestinal necrosis admitted at Xijing Hospital of Air Force Military Medical University from Jan 2008 to Dec 2020 were retrospectively analyzed.Results:A total of 46 patients were included. The 30-day overall mortality rate was 19.6%, and that of those treated by enterostomy after enterectomy was 12.1%, and that was 38.5% in those undergoing primary entero-anastomosis after enterectomy. Univariate analysis showed that rebound pain was positive ( P=0.025), MAP was higher than 105mmHg ( P=0.04), heart rate was less than 120 beats/min ( P=0.04), and Fullen intestinal ischemia grade ( P=0.03) was significantly related to survival rates. Conclusions:Rebound pain, MAP, heart rate, Fullen grade, and surgical methods significantly affect the prognosis of patients. More patients survive with intestinal resection and enterostomy than those with intestinal resection and immediate anastomosis.

Objective To systemically review andquantify the incidence of oral feeding intolerance in acute pancreatitis. Methods Randomized controlled trials that reported the oral feeding intolerance rates of acute pancreatitis were searchedfrom PubMed, EMBASE, Medline, Cochrane Library, WanFang, CNKI, CMCC and VIP dal,abase wilh the" Acute pancreatitis " " Feeding intolerance" " Incidence" " Meta- analysis "from January 2002 to May 2017. Date were analyzed by using R 3. 4. 0 software. The heterogeneity of data were analyzed using 12test. Results Eleven randomized controlled trials including 658 cases were enrolled in Meta-analysis. The incidence of oral feeding of intolerance was 12. 2% . The result of subgroup analysis showed that there were no significant difference in the incidence of oral feeding intolerance when region, sample size and published year were taken into analysis (P > 0. 05). The oral feeding intolerance rate of mild acute pancreatitis was lower than that when moderately severe acute pancreatitis and severe acute pancreatitis were, included (8. 2% and 19. 9% , respectively; P = 0. 002 7). Conclusion Oral feeding intolerance affects approximately l in 8 patients with acute pancreatitis. The incidence of oral feeding intolerance of patients with severe acute pancreatitis is higher than that of patients with mild acute pancreatitis
