20.500.12556/DKUM-82303 Vpliv mesta in metode odvzema krvi na število hemoliz pri odvzetih vzorcih v urgentnem centru Influence of location and method of blood collection on the number of hemolysis in the samples taken in emergency department Uvod: Za pregled krvne slike potrebujemo vzorec bolnikove krvi. Za odvzem lahko izberemo različne metode in mesta. Pri odvzemu vzorcev lahko zaradi različnih dejavnikov vpliva pride do pojava hemolize. Metode: Uporabili smo kvantitativno metodologijo dela. Pri teoretičnem delu smo uporabili deskriptivno metodo dela in v raziskovalnem delu izbrali neslučajnostni namenski raziskovalni vzorec. Pri obdelavi rezultatov smo uporabili programa Microsoft Office Professional Plus in IBM SPSS ter uporabili hi-kvadrat in t-test. Rezultati: Večji pojav hemoliziranih vzorcev smo dobili pri odvzemih na distalnem delu roke v 34% v primerjavi s kubitalnim predelom v 14%. Prav tako je pojavnost pri vakuumskih odvzemih v 32% proti brizgalki v 12%. Pri manjših intravenskih kanilah je pojav hemolize v 36% in pri večjih v 14%. V primerjavi odvzemov z iglo in intravensko kanilo je pojavnost manjša pri igli v 6% proti 13% pri kanili. Pri časovnem zažemu žile > 60 s se je hemoliza pojavila v 14%, pri < 60 s pa v 10%. Med hemoliziranimi vzorci je bil v 88,8% vzrok odvzem z IV kanilo in njena velikost. Vrednosti kalija so bile povišane v hemoliziranih vzorcih in so pokazale statistično pomembne razlike (p = 0,002). Sklep: Pojavnost hemoliz je večja predvsem pri odvzemih z manjšimi IV kanilami in z vakuumskim sistemom ter v distalnem področju roke. Pri več kot polovici primerov hemoliz je bil vzrok odvzem iz intravenske kanile in njena velikost. V hemoliziranih vzorcih so vrednosti kalija povišane. Introduction: A sample of the patient's blood is needed to analyse their blood count. Different locations and methods can be chosen to draw blood. Different factors can cause haemolysis to occur when drawing samples. Methods: A quantitative method has been used. The theoretic part used a descriptive method, and the research used a non-probability research sample. To process the results, Microsoft Office Professional Plus and IBM SPSS as well as a chi-square and a t-test have been used. Results: A larger occurrence of haemolytic samples, 34%, has been recorded when drawing blood from the distal part of the arm as opposed to 12% from the cubital part. Furthermore, 32% of samples were haemolytic when drawing blood via vacuum as opposed to 12% when drawing blood via syringe. 36% of samples drawn with smaller intravenous cannulae indicated haemolysis and 14% of samples drawn with larger cannulae. In comparison to drawn samples via syringe and intravenous cannulae, haemolysis occurred in 6 and 13% of samples respectively. When the circulation was cut off in over 60 s, haemolysis occurred in 14% of samples and 10% when it was cut off in under 60 s. The cause of 88,8% of haemolytic samples was drawing via an IV cannula and its size. The potassium amounts were increased in haemolytic samples and have shown a statistically significant difference (p = 0,002). Conclusion: Haemolysis occurrence is larger especially when drawing blood with smaller IV cannulae and via vacuum, as well as from the distal part of the arm. Over half of haemolytic samples were caused by drawing blood via IV cannula and due to its size. The haemolytic samples showed an increase in potassium amounts. hemoliza odvzem krvi vzorec krvi intravenska kanila haemolysis drawing blood blood sample intravenous cannulae true true false [K.
