Abstract
Kopsavilkums
Ievads: Apgūstot otorinolaringoloģijas speciālista profesiju, viens no lielākajiem izaicinājumiem ir nepieciešamo praktisko iemaņu attīstīšana. Apmācībās klīniskajā praksē ir jāpanāk līdzsvars starp iemaņu pilnveidošanu un pacienta drošību. Attīstoties mūsdienu ražošanas tehnoloģijām, ar vien biežāk tiek pielietoti medicīnisko manipulāciju un klīnisko scenāriju simulatori. Tie rada drošu apmācības vidi, kurā kļūdotiestiek gūta pieredze nevis paaugstināts risks pacientam. Sīkās un smalkās anatomijas dēļ, otorinolaringoloģijas praksē jo sevišķi ir nepieciešama iespēja vizuāli un praktiski parādīt un izmēģināt procedūru, pirms to veikt klīniskajā praksē.
Mērķis: Galvenais darba mērķis bija fukncionāla timpanostomijas trenažiera izstrāde un tā funkcionālā novērtēšana.
Metodes: Tika veikta pieejamās literatūras izpēte izmantojot PubMed datubāzi, aspkatīts 3D drukas iekārtu tirgus un to programmatūras nodrošinājums. Izmantojot brīvprātīgi piešķirtus pacienta izmeklēšanas datus, tika izstrādāts funkcionāls timpanostomijas trenažiera prototips, veikta tā aprobācija izmantojot anketu. Anketas dati tika anlizēti izmantojot SPSS 22.0 (IBM Company, Čikāga, Ilinoisa, ASV) programmu. Dati tika analizēti, izmantojot Kraskela – Vollisa testu, Duneta pāru testu un Bonferoni korekciju.
Rezultāti: Respondentiem tika lūgts novērtēt trenažiera līdzību cilvēka audiem un novērtēt to, cik viegli bija veikt timpanostomijas ievietošanas manipulāciju. Abās vērtēšanas kategorijās tika izmantota skala no 1 līdz 5 ballēm. Tika atklāta statistiski nozīmīga vidējo rangu atšķirība grūtības pakāpes novērtējumā (p=0,044) starp sertificētiem ārstiem, ārstiem rezidentiem un medicīnas studentiem, kā arī, ka pastāv statistiski nozīmīga atšķirība (p=0,042), starp to, kā timpanostomas ievietošanas grūtības pakāpi novērtēja medicīnas studenti un ārsti rezidenti. Starp specializācijas grupām netika atklāta statistiski nozīmīga atšķirība līdzības novērtējumā (p=0,070)
Secinājumi: Mūsdienu 3D ražošanas tehnoloģijas ir pietiekami attīstītas un pieejamas, lai dotu iespēju izstrādāt funkcionālus medicīnisko manipulāciju trenažierus.
Abstract Introduction: One of the major challenges of becoming and otorhinolaryngologist is the acquisition of the necessary practical skills associated with this profession. The educational environment must balance between the practical benefit for the pupil and the risk to the patients’ health. With the advent of modern manufacturing technologies, the use of medical procedure and clinical scenario simulators has only been increasing. They provide a safe educational environment where mistakes are risk free and only serve to benefit the learning experience. Otorhinolaryngology is associated with fine, minute and tight anatomical spaces, which is why there is an especially high demand for the ability to showcase and practice otorhinolaryngological manipulations beforehand. Aim: The main goal of this study was to create a functional tympanostomy trainer prototype and evaluate its overall performance. Methods: A review of available literature on the topic was performed using the PubMed publication database. An evaluation of the current 3D printer market and software support was performed. A functional prototype was developed using volunteer patient investigation data and evaluated using as survey. Analysis of the gathered survey data was performed using IBM SPSS (IBM Company, Chicago, Illinois, USA). Kruskal-Wallis test, Dunnett’s test and Bonferroni correction were used to analyse the data. Results: Respondents were asked to evaluate the prototype in two regards – similarity to human tissue and how hard was it to perform the manipulation of ear tube insertion. In both cases a scale from 1 to 5 was used for evaluation. Statistically significant differences were found between mean evaluations (p=0.044) of hardness and overall evaluations (p=0.042) of hardness regarding level of specialization (medical students, resident doctors and specialists). No statistically significant differences were found between the levels of specialization regarding similarity (p=0.070) Conclusion: Currently available 3D manufacturing technology is both accessible and capable of producing functional medical simulator prototypes.
