“…These include assessment of change in the red-cell volume calculated on the basis of estimated red cell mass 11 or hematocrit, 12 colorimetric technique, 13 and a gravimetric method such as our own, which requires weighing materials such as laparotomy sponges on a scale and subtracting known weights of the dry surgical materials from blood-soaked materials to calculate the volume of blood loss. 14 Our method of assessment differs from other gravimetric methods in that it compares the weight of blood in soaked gauze and drape with that of 10 mL of blood from the same patient at the time of the procedure. Although little variance was observed in the weight of 10 cm 3 of blood from subject to subject (12.4 g AE 0.13 SD), usage of the mean value of 12.4 g for all subjects in the calculation of blood loss will introduce assumptions into the methodology and may significantly reduce the accuracy of this method of blood loss estimation.…”

Anemia is an important complication of chronic renal disease, with a significant impact on the morbidity, quality of life, and mortality in this group of patients. Inadequate erythropoietin production, reduced life span of erythrocytes in uremic serum, bone marrow suppression by uremic toxins, chronic inflammation, and contaminants in the water treatment unit are recognized etiological causes of anemia in chronic kidney disease patients. Little attention has been paid to possible contributions of small but continual loss of blood during vascular access cannulation for hemodialysis in these patients. The aim of this study is to quantify the volume of blood loss during femoral vein cannulation in patients on hemodialysis. The average volume of blood loss during femoral cannulation was evaluated using a simple and inexpensive procedure of deriving volume of blood lost, from the weights of soaked gauze and drape during the access cannulation procedure. The mean blood loss per procedure during femoral cannulation was 36.52 mL+/-2.70 SD, with a range of 6.47 to 100.20 mL. The calculated average weekly loss in patients on thrice-weekly dialysis schedule is 109.56 mL of blood, with a monthly loss of 438.24 mL. Cumulative blood loss during femoral vein cannulation appears to be significant. Its contribution in the sustenance of anemia in hemodialysis patients deserves further evaluation.

“…She stated the figure to be somewhere between 25-50 cm3. The medical literature (Alderman 1975, Buchman 1953, Clark et al 1955, Steward & Rourke 1938 revealed that estimating blood loss is extremely difficult and inaccurate. Not only is estimation of blood loss not exact; with wide margins of error, but blood loss tends to be underestimated during obstetrical emergencies, as well as routine procedures.…”

Estimation is the most commonly used method to determine blood loss. According to the literature, estimating blood loss is not exact; there are wide margins of error and blood loss tends to be underestimated. Forty-two registered nurses were asked to estimate varied amounts of blood on 20 peripads. Both over- and underestimation occurred; 71% overestimated and 25% underestimated blood loss. There was also disagreement as to what constituted heavy, moderate or slight blood loss. There was no difference in accuracy among variables of education, years of experience, specialty area, or when and how nurses learned to estimate. Contrary to current literature, these nurses: 1 overestimated blood loss; 2 had significant difficulty in estimating very small and very large amounts of blood; 3 although in error, were consistent in estimating repeated samples with the same amounts of blood; 4 were not consistent in estimating heavy, moderate, and slight blood loss.

“…The operation can be traumatic, with blood loss as high as mean 850ml. [5], possibly related to severing of CLs which contains uterine artery branches and also, failure of Sturmdorf sutures to control bleeding from cervical amputation.…”

Our minimally invasive Fothergill-Manchester technique aims to decrease blood loss and surgical trauma and to preserve function by1. Vaginal conservation. 2. Cardinal (CL) and uterosacral (USL) ligaments plicated, not severed. 3. Direct suture of vagina to cervix without Sturmdorf sutures after cervical amputation. 4. Use of No2 polyester sutures to create new collagen to reinforce the plicated ligaments.
