The effects of operation about blood parameters

This study is a descriptive study that was planned on 4 patient groups tu examine the impact of surgical interventions on blood parameters. Our study groups consisted of a total of 100 patients that cholecystectomy, tyroidectomy, hernioraphy, and GIS operations were applied in the General Surgery Clinic of SSK Bursa Regional Hospital between the July 2002 and January 2003. Characteristics of the patients like age, gender, educational level, length of hospitalization period were studied, and blood values like blood pressure, hemoglobin, hematocrite, leucocytes, red blood cells, and platelets were taken once pre-operatively and three times post-operatively, and 4 groups were compared. In addition, it was taken into consideration if patients were given intra-venous fluids or blood transfusion. 62% (n=62) of the patients included in the study were females, and 38% (n=38) of them were males. The average age of all the patients and the standard deviation was 50,5±15,2. The average period of hospitalization for the entire group and the standard deviation was 6,9+4,3. It was observed that the systolic blood pressures of the patients that were operated showed a tendency for lowering throughout the 3 measurements in the post-operative period; and these decreases were significant when compared with measurements in pre-operative period. According to the averages of the diastolic blood pressures of the entire group, no statistically significant decrease was seen, although the average diastolic blood pressures in the day of the operation and the first post-operative day. Significant decreases were seen in the post-operative hemoglobin and hematocrite averages according to pre operative measurements. For the entire group, the day that the leukocyte values were highest were 0th day and 1 * post-operative days respectively, and those values were significantly higher when compared to pre-operative period. Red blood cell count showed significant increase in the third measurement in the 3rd post-operative day according to pre-operative period; however, the decrease in post-operative measurements remained the same. It was found that the platelet count showed the greatest decrease it the day of the operation. In our study, we saw that only a total 7 patients from the GIS group received blood transfusion. As a result, factors like performing a good surgical intervention, performing the routine tests, performing bleeding controls without omission, and keeping the operation time in the pre- operative period will influence parameters like hemoglobin, hematocrite, leukocyte count, red blood cell count, platelet count, and systolic-diastolic blood pressure. By anticipating the possible changes in these parameters and performing the appropriate surgical technique and treatments these values can be kept within normal limits, and thus unnecessary blood transfusions and fluid administrations and development of post-operative complications can be prevented.
