[Prevalence of blood transfusion after primary total hip arthroplasty]. / A vértranszfúzió gyakorisága primer csípoprotézis-beültetés után.

Introduction: Total hip arthroplasty is one of the most common surgical procedures that requires blood transfusion, with the possible risk of significant complications. Aim: A retrospective study was performed to analyze the predictors of blood transfusion after primary total hip arthroplasty. Method: We collected the data of 210 consecutive patients undergoing total hip arthroplasty. Patient's data, preoperative hemoglobin and hematocrit level, the type of the prosthesis, the use of a suction drain, tranexamic acid or anticoagulants and the type and amount of blood transfusion were recorded. Results: A total of 41% of our patients required transfusion, 8.6% receiving allogenic blood. Significant predictors of allogenic blood transfusion were preoperative hemoglobin and hematocrit levels, the type of prosthesis, the use of suction drainage and the use of tranexamic acid. Patients with pre-donated autologous blood did not require allogenic blood transfusion. Conclusion: Based on our study, total hip arthroplasty necessitates allogenic blood transfusion in 8.6%. Major predictors associated with the need for transfusion are preoperative hemoglobin and hematocrit levels, the type of prosthesis, the use of suction drainage and the use of tranexamic acid. Pre-donated autologous blood helps to reduce allogenic transfusion rate. Orv Hetil. 2020; 161(8): 290-294.

M-mode and two-dimensional echocardiographic reference values for three Hungarian dog breeds: Hungarian Vizsla, Mudi and Hungarian Greyhound.

The aim of the study was to establish normal reference echocardiographic values for three Hungarian dog breeds, and to determine the potential dependence of intracardiac parameters on body weight, age and gender. M-mode and two-dimensional echocardiography were performed on 95 clinically healthy dogs including 45 Hungarian Vizslas, 28 Mudis and 22 Hungarian Greyhounds. Linear intracardiac measurements included interventricular septal thickness (IVS), left ventricular internal diameter (LVID), left ventricular posterior wall thickness (LVPW) both in systole and diastole, as well as left atrial internal diameter (LAD), and aortic diameter (AOD) in early diastole. Fractional shortening (FS), end-diastolic and end-systolic left ventricular volumes (EDV and ESV), as well as LAD:AOD ratio were calculated from the linear parameters. Mean, range and standard deviation of measurements were calculated for each breed. Body weight positively correlated in all three breeds with all left ventricular dimensions, such as IVS d , IVS s , LVID d , LVIDD s , LVPW d and LVPW s parameters. LA values showed positive correlations to body weight in all three breeds. AOD and LA demonstrated a positive correlation with body weight in Hungarian Vizslas and Mudis, whilst the LAD:AOD ratio was related to body weight only in Mudis. Gender did not correlate with any of the measured echocardiographic parameters in any breeds. In Mudis, a positive correlation was found between the LAD: AOD ratio and age, as well as between the LAD: AOD ratio and E point to septal separation (EPSS).
