Objective To analyze the characteristics of postoperative hospital-acquired infections and drug sensitivity in lung transplant recipients over the past 5 years in a single center. Methods A total of 724 lung transplant recipients at Wuxi People's Hospital from January 2019 to December 2023 were selected. Based on the principles of hospital-acquired infection diagnosis, a retrospective analysis was conducted on the hospital infection situation and infection sites of lung transplant recipients, and an analysis of the distribution of hospital-acquired infection pathogens and their antimicrobial susceptibility test status was performed. Results Among the 724 lung transplant recipients, 275 cases of hospital-acquired infection occurred, with an infection rate of 38.0%. The case-time infection rate decreased from 54.2% in 2019 to 22.8% in 2023, showing a downward trend year by year (Z=30.98, P<0.001). The main infection site was the lower respiratory tract, accounting for 73.6%. The pathogens were mainly Gram-negative bacteria, with the top four being Acinetobacter baumannii (37.1%), Pseudomonas aeruginosa (17.3%), Klebsiella pneumoniae (13.7%), and Stenotrophomonas maltophilia (13.4%), with imipenem resistance rates of 89%, 53%, 58% and 100%, respectively. Gram-positive bacteria were mainly Staphylococcus aureus (3.6%), with a methicillin resistance rate of 67%. Conclusions Over the past 5 years, the hospital-acquired infections in lung transplant recipients have shown a downward trend, mainly involving lower respiratory tract infections, with the main pathogens being Acinetobacter baumannii, Pseudomonas aeruginosa and Klebsiella pneumoniae, all of which have high resistance rates to imipenem.

Objective:To summarize the best evidence for early enteral nutrition support in postoperative patients with gastric cancer and evaluate its effectiveness.Methods:From March to August 2021, 108 postoperative patients with gastric cancer admitted to the Gastrointestinal Surgery of the First Affiliated Hospital of Ningbo University were selected. We applied evidence-based nursing methods to summarize the best evidence for early enteral nutrition support in postoperative gastric cancer patients, and constructed and implemented the best evidence application strategy through baseline review, evaluation of evidence application clinical scenarios and barriers. We compared the various indicators of two groups of patients before the application of evidence (March to May 2021, n=55) and after the application of evidence (June to August 2021, n=53) . Results:No adverse events occurred during the application of evidence. After applying evidence, the correct nutritional assessment rate increased from 41.82% (23/55) at baseline review to 90.57% (48/53), the implementation rate of early postoperative enteral nutrition increased from 0 to 45.28% (24/53), the start time of postoperative enteral nutrition shortened from (3.75±2.33) days to (2.06±1.38) days, and the implementation rate of postoperative priority oral nutrition increased from 63.64% (35/55) to 86.79% (46/53), nutritional related complications decreased from 40.00% (22/55) to 20.75% (11/53), and the differences were all statistically significant ( P<0.05) . Conclusions:The application of the best evidence for early enteral nutrition support in postoperative gastric cancer patients can shorten the start time of postoperative enteral nutrition, reduce postoperative nutrition related complications, and promote early recovery of patients.

Objective:To retrieve relevant evidence for early enteral nutrition support in patients after gastric cancer surgery and summarize the best evidence, so as to provide evidence-based evidence for clinical implementation of postoperative enteral nutrition management for gastric cancer.Methods:Evidence-based questions were established according to PIPOST principles, UpToDate, Cochrane Library, Joanna Briggs Institute Library, BMJ Best Practice, Agency for Healthcare Research and Quality website, Medlive, European Society for Clinical Nutrition and Metabolism website, American Society for Parenteral and Enteral Nutrition website, Embase, Medline, PubMed, SinoMed, Wanfang Database, China National Knowledge Infrastructure were searched according to the "6S" evidence model. The retrieval period of every database was from January 1, 2016 to May 31, 2021. The Evidence Pre-Grading and Evidence Recommendation Grading System (2014) of Australian Joanna Briggs Institute Evidence-Based Health Care Center was used to extract evidence from the literature that met the quality standards, determine the evidence grading and recommendation level and form the best evidence.Results:A total of 317 literatures were retrieved, and 10 literatures were included, including 1 guideline, 4 expert consensus and 5 systematic reviews. The 10 evidences were summarized from 4 aspects, including indication evaluation, timing management, route and preparation management and risk management.Conclusions:Current evidence shows that early enteral nutrition is safe and feasible in patients after gastric cancer surgery. In the process of implementing enteral nutrition, medical staff should fully evaluate the indications and needs of patients and make clear and prudent choices for nutritional support channels and preparations of patients, so as to form the best evidence and clinical management programs for early enteral nutrition support for patients after gastric cancer surgery and accelerate postoperative recovery of patients.

There were statistically significant differences in the quality of life between the two groups, except for cognitive function, sleep and economic status ( P<0.05) . The satisfaction with the medical and nursing staff in the control group was 79.03% (49/62) lower than 92.45% (49/53) in the intervention group, and the difference between the two groups was statistically significant ( P<0.05) . Conclusions:The evidence-based bundled and continuing nursing measures can improve the compliance, quality of life and satisfaction with the medical nursing staff in patients undergoing the first chemotherapy after gastric cancer surgery.

Objective: To explore the effect of early enteral nutrition(EEN) and parenteral nutrition(PN) on the postoperative outcomes of patients with gastric cancer and nutritional risk in enhanced recovery after surgery. Methods: A total of 130 patients with gastric cancer hospitalized in department of surgery of Ningbo First Hospitalfrom September 2016 to May 2018 were selected and divided into early enteral nutrition support group (EEN) which was placed with jejunal nutrition tube during the operation, and enteral nutrition started within 12-24 hours after the operation, and parenteral nutrition support group (PN) which was given parenteral nutrition support one day after surgery. Patients in both groups were given nutrients of equal heat and nitrogen.The incidence of nutrition-related complications, the incidence of infection-related complications, the length of postoperative hospital stay and the time of anal exhaust were compared between the two groups. Results: The incidence of nutrition-related complications was 10 cases (15.38%) and 4 cases (6.15%)in EEN group and PN group, that was not statistically different (P=0.157). The incidence of infection-related complications was 3 cases (4.61%) and 5 cases (7.69%) in EEN group and PN group, that was not statistically different (P=0.715). The postoperative hospital stay was 11 days (range, 10-15) and 12 days (range, 11-13)in EEN group and PN group, that was not statistically different (P=0.233). The first anal exhaust time and defecation timewere 64 hours (range, 52-77) and 87 hours (range, 76-100) in EEN group and 72 hours(range, 60-86) and 96 hours(range, 86-120) in PN group, that was statistically different(P=0.001, P=0.034). Conclusion Enhanced recovery after surgery, early enteral nutrition after gastric cancer surgery may promote the recovery of intestinal function, but the complications and hospital stay after operation are not improved.

Objective? To investigate the effect and safety of high-flow nasal cannula (HFNC) oxygen therapy for patients after extubation in lung transplantation. Methods? A retrospective study was conducted on 60 hospitalized patients with lung transplant during January 2017 to December 2017 in Wuxi People＇s Hospital. According to the different methods of respiratory support prescribed after extubation, the patients were divided into two groups: observation group (n=28, via HFNC) and control group (n=32, via nasal oxygen tube) . The two groups were compared in terms of the clinical indicators including their blood gas analysis(oxygenation index, lactic acid, partial pressure of carbon dioxide) , viscosity of sputum and comfort, etc. Results? Six hours after extubation and before transferring to other departments, the observation group＇s oxygenation index was(263.70±48.97)and(273.22±43.26)mmHg, which were statistically different from those of the control group with (217.83±77.30)and(229.08±68.64)mmHg respectively (P＜ 0.05). Before transferring to other departments, the partial pressure of carbon dioxide in the observation group was (37.04±8.56)mmHg, lower than the control group with (42.43±6.14)mmHg with a statistical difference (P＜0.05); the viscosity of sputum in the obseration group was lower than the control group with statistical difference (P＜0.05); the patients＇ comfort in the observation group achieved (7.72±1.06)points, higher than the control group＇s (4.39±0.82)points with statistical difference (P＜ 0.05). Conclusions? HFNC oxygen therapy for the patients after extubation in lung transplantation has good effects, is safe and reliable, and can be widely applied in clinical practice.

Objective? To construct a nursing intervention model based on the theory of planned behavio(r TPB), to prevent deep venous thrombosis (DVT) of lower extremities, and to explore its application in patients with gastrointestinal cancer after operation. Methods? By convenience sampling, a total of 163 patients admitted in the Department of Gastrointestinal Surgery, Ningbo First Hospital, Zhejiang Province who underwent gastrointestinal surgeries from January to December in 2018 were selected as the research objects in this study. The 79 patients admitted from January to June in 2018 were taken as the control group and the conventional perioperative DVT prevention nursing care was given. The other 84 patients admitted from July to December in 2018 were taken as the observation group and the TPB based DVT nursing intervention model was adopted. The two groups were compared in terms of the patient's scores in cognition about DVT, postoperative ankle pump movement, quadriceps femoris movement, first out-of-bed activity within 24 hours and compliance with walking target volume within 3 days after surgery, as well as the number of cases of DVT during hospitalization after surgery. Results? The score of DVT knowledge in the observation group was higher than that in the control group; the compliance of ankle pump movement, quadriceps femoris movement and the proportion of patients getting out of bed for the first time within 24 hours after operation in the observation group were higher than those in the control group; the differences between the two groups were statistically significant (P＜0.05). The rate of achieving 500 m walking goal in the observation group was higher than that in the control group 3 days after operation, but there was no significant difference between the two groups (P＞0.05). There were 7 cases of DVT in control group and 1 case in observation group after operation, and there was statistically significant difference between the two groups (P＜0.05). Conclusions? The DVT nursing intervention model based on TPB is helpful to improve the cognitive level of DVT in patients undergoing gastrointestinal cancer surgery, improve the compliance of lower limb activities and early ambulation, and reduce the incidence of DVT after surgery, establish good healthy behavior for patients undergoing gastrointestinal cancer surgery and effectively prevent DVT.

Objective? To explore the application effects of bundle care strategy to enhanced recovery after surgery (ERAS) based on evidence-based nursing practice for patients with gastric cancer during perioperative period. Methods? From July 2017 to June 2018, a total of 100 patients undergoing radical gastrectomy in Ningbo First Hospital were selected and divided into control group and observation group according to admission time, with 50 cases in each group. The control group received routine enhanced recovery nursing based on guidelines. Bundles of care was determined and implemented in the observation group based on the embodiment of ERAS after literature review combined with expert consultation. The first anal exhaust time, defecation time, ambulation time, hospitalization days, ADL score on the third day after operation, pain score at 24 and 48 hours after operation, and complications of infection were compared between the two groups. Results? The first anal exhaust time, defecation time and ambulation time of the observation group were 66 (53,78) h, 88 (76,100) h and 29 (24,36) h, which were all lower than those of the control group [72 (60,90) h, 96 (82,120) h and 36 (24,48) h], and the differences were statistically significant (P＜0.05). The ADL score on the third day after operation was (65.88±14.37), which was higher than that of the control group (59.18±14.31), and the difference was statistically significant (P＜0.05). The hospitalization duration of the observation group was 11 (10,12) days, which was shorter than that of the control group 12 (11,13) days, and the difference was statistically significant (P＜0.05). There was no statistical significance in the difference in the pain score at 24 and 48 hours after operation and the complications of infection between the two groups (P＞0.05). Conclusions? Bundle care strategy of enhanced recovery after surgery for patients with gastric cancer can promote postoperative gastrointestinal function recovery, improve postoperative self-care ability and shorten postoperative hospital stay.
