In early 2022, the online survey was sent to nurses who worked in the intensive care unit (ICU) or another critical care unit across the country as part of a cross-sectional survey. The study got a total of 70 answers for the RRT modalities, which are currently available and representative of the capacity of treatment for individual institutions. In terms of modality, intermittent hemodialysis (IHD) and continuous renal replacement therapy (CRRT) are the most commonly available and used treatment for AKI in Thailand’s ICUs. These options are accessible for RRT in the acute setting in this survey, with a rate of as high as 71.43% and 61.43% available across the country, respectively. Additionally, the other options are also available, including either manual or automated peritoneal dialysis (PD), and sustained low efficiency dialysis (SLED).","PeriodicalId":177401,"journal":{"name":"2022 14th Biomedical Engineering International Conference (BMEiCON)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122986792","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With the aim of reducing the workload of doctors, task shifting was planned and the CE Law was revised in 2021. Even in Thailand, there is a chronic shortage of medical personnel such as doctors and nurses, and from the perspective of patient safety, it is recognized that specialists in the maintenance and operation of medical devices are essential. In the future, it will be necessary to develop personnel with an eye on the task shifting of Biomedical Engineer (BME) in the field where the diversification of medical devices is expected. In 2019 and 2020, we conducted training for BME training on medical devices made in Japan in this project. Establishment of medical safety for patients became a common issue in the future. The 2021 training focused on team medical care participation, monitoring of critically ill patients, and ECMO and CRRT under mechanical ventilation, especially in the ICU. By making CEs’ participation in ICU team medical care the content of the training, we were able to present problems that would arise as medical devices become more complex in the future, and gain the understanding of the Thai side. In Japan, there is a successful example of a task shifting from doctors to CEs. In Thailand, TPQI (Thailand Professional Qualification Institute) has been established as a standard for BME’s professional ability. Through this project, the Thai side will deepen its knowledge of Japanese-made medical devices and use it for training at its own facility, and as medical devices becomes more diverse and complex in the future, it will be possible to understand the experience of participating in team medical care in Japan. We hope that this will lead to improvements in medical safety.","PeriodicalId":177401,"journal":{"name":"2022 14th Biomedical Engineering International Conference (BMEiCON)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128536491","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this study was to investigate different pretreatment conditions combined with gamma irradiation to establish the processing condition for long-term preservation of amniotic membranes as biological wound dressings. Human amniotic membranes (hAMs) were first isolated from donated placentas obtained by caseation, cleaned off blood remnants, and cut into 10 cm $times 10 cm$ sheets. During the pretreatment step, 0.05 - 0.5% (w/v) hypochlorite solution or a combination of penicillin-streptomycin, neomycin, and amphotericin (PNA) solution at 50, 100, and 2.5 $mu$ g/mL, respectively, was first performed to reduce bacterial contamination. After air drying under sterile environment, the amniotic sheets were individually packed and tightly sealed in double-layered polyethylene bags before exposed to gamma irradiation at 25 kGy under cold condition. Plate count methods were performed on as-received hAMs and after pretreatment and gamma irradiation steps to check the bacterial contamination on the samples. Results showed that pretreating the amniotic membranes in 0.5% (w/v) hypochlorite for 2 h or PNA for 18 h could sufficiently reduce the bacterial contamination below 103 colony-forming unit, and gamma irradiation under cold condition could maintain the membranes’ transparency as well as ensure the sterility of samples up to 6 months. Therefore, this combined pretreatment and irradiation steps could be applied to preserve dried hAMs for long-term use as wound dressings.","PeriodicalId":177401,"journal":{"name":"2022 14th Biomedical Engineering International Conference (BMEiCON)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131330006","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although changes in membrane morphology are one cause of cytotoxicity, the effects of cut CNTs on membrane morphology are not well understood.
