Excessive Blood Loss

SummaryThe effect of desmopressin (DDAVP) on reducing postoperative blood loss after cardiac surgery has been studied in several randomized clinical trials, with conflicting outcomes. Since most trials had insufficient statistical power to detect true differences in blood loss, we performed a meta-analysis of data from relevant studies. Seventeen randomized, double-blind, placebo-controlled trials were analyzed, which included 1171 patients undergoing cardiac surgery for various indications; 579 of them were treated with desmopressin and 592 with placebo. Efficacy parameters were blood loss volumes and transfusion requirements. Desmopressin significantly reduced postoperative blood loss by 9%, but had no statistically significant effect on transfusion requirements. A subanalysis revealed that desmopressin had no protective effects in trials in which the mean blood loss in placebo-treated patients fell in the lower and middle thirds of distribution of blood losses (687-1108 ml/24 h). In contrast, in trials in which the mean blood loss in placebo-treated patients fell in the upper third of distribution (>1109 ml/24 h), desmopressin significantly decreased postoperative blood loss by 34%. Insufficient data were available to perform a sub-analysis on transfusion requirements. Therefore, desmopressin significantly reduces blood loss only in cardiac operations which induce excessive blood loss. Further studies are called to validate the results of this meta-analysis and to identify predictors of excessive blood loss after cardiac surgery.

High Dose Aprotinin

Fifty patients undergoing primary coronary artery bypass surgery and 50 patients undergoing valve surgery received either high-dose aprotinin (2 million units loading dose, 2 million units added to the CPB prime, and 500,000 units/hr maintenance infusion) or placebo. Mean postoperative blood loss in the first six hours was reduced from 321 ml in the placebo group to 172 ml in the aprotinin group (95% confidence interval (CI) for difference = 95 to 189 ml). Seven patients in the placebo group and 16 patients in the aprotinin group did not require transfusion with homologous blood. This study adds to the growing body of evidence that the administration of high-dose aprotinin reduces blood loss and blood transfusion requirements associated with primary cardiac surgery.

Background: The antifibrinolytic drug tranexamic acid (TA) decreases blood loss in Pediatric patients under going cardiac Surgery. However its efficacy has not been extensively studied in children. Method: We examined 750 children under going cardiac surgery form 2004 to 2007 in National Institute of Cardiovascular Diseases (NICVD), 379 children in the Tranexamic Acid group (TA) and 371 included in placebo (P) group. After induction of anesthesia and prior to skin incision, patients received either tranexamic acid (10mg/kg followed by 1mg/kg/hr) and saline placebo. After admission to intensive care unit total blood loss and transfusion requirements during the first12 hours were recorded. Result: Children who were treated with tranexamic acid had 24% less total blood loss (26±7 vs 34±17 ml/kg) compared with children who received placebo (p<0.05). Additionally, the total transfusion requirements, total donor unit exposure and financial cost of blood components were less in the tranexamic acid group. Conclusion: Tranexamic acid can reduce perioperative blood loss in children undergoing cardiac surgery.Keywords: Tranexemic acid; Cardiac surgery; Post operative; bleeding DOI: http://dx.doi.org/10.3329/cardio.v1i2.8127 Cardiovasc. j. 2009; 1(2) : 189-192

Secondary Outcomes

This systematic review and meta-analysis was conducted to evaluate the safety of gelatin versus hydroxyethyl starches (HES) and crystalloids when used for cardiopulmonary bypass (CPB)-priming in cardiac surgery. MEDLINE (Pubmed), Embase and CENTRAL were searched. We included only randomized, controlled trials comparing CPB-priming with gelatin with either crystalloids or HES-solutions of the newest generation. The primary endpoint was the blood loss during the first 24 hours. Secondary outcomes included perioperative transfusion requirements, postoperative kidney function, postoperative ventilation times and length of stay on the intensive care unit. Sixteen studies were identified, of which only ten met the inclusion criteria, representing a total of 824 adult patients: 4 studies compared gelatin with crystalloid, and 6 studies gelatin with HES priming. Only 2 of the studies comparing HES and gelatin reported postoperative blood loss after 24 hours. No significant difference in postoperative blood loss was found when results of both studies were pooled (SMD -0.12; 95% CI: -0.49, 0.25; P=0.52). Likewise, the pooled results of 3 studies comparing gelatin and crystalloids as a priming solution could not demonstrate significant differences in postoperative bleeding after 24 hours (SMD -0.07; 95% CI: -0.40, 0.26; P=0.68). No differences regarding any of the secondary outcomes could be identified. This systematic review suggests gelatins to have a safety profile which is non-inferior to modern-generation tetrastarches or crystalloids. However, the grade of evidence is rated low owing to the poor methodological quality of the included studies, due to inconsistent outcome reporting and lack of uniform endpoint definitions.

Background. Platelet count (PLT), activated partial thromboplastin time (APTT), prothrombin time (PT) and fibrinogen are standard coagulation tests used for patients undergoing cardiac surgery with cardiopulmonary bypass (CPB). Materials and methods. 83 adult cardiac surgery patients were en­ rolled into a prospective study. Blood samples for APTT, PT, PLT, fibrino­ gen were collected preoperatively (T0), on admission to the intensive care unit (T1), 6 and 24 hours postoperatively (T6, T24). 24-hour postopera­ tive blood loss (24h-PBL) was registered. Results. The highest APTT mean value was 47  ±  13 sec at T6, in­ creasing from the baseline by 37%. The lowest mean value of PLT was 140 ± 47 × 109/L at T24, decreasing from the baseline by 32.5%. PT and fibrinogen mean values at all time points were within the normal range. Correlation with 24h-PBL was shown by T0 and T6 fibrinogen (r = –0.5, r  =  –0.4, P
