“…1,5,[27][28][29][30] For pediatric liver transplants, apart from retransplantation, factors that have been associated with increased intraoperative blood losses include: hypoplastic portal vein, use of a reduced-size liver graft, requirement of in-hospital supportive care, intra-abdominal malformations and signs of severe liver failure (encephalopathy, ascites, prolonged PT). 20,[31][32][33] Children younger than two years, and particularly those under one year of age experience higher blood loss. 34,35 Transplantation of a reduced (fraction of an adult human organ) liver not only increases intra-and postoperative blood loss, but has been associated with an increase in the percentage of patients undergoing reoperation for continued blood loss, from 9.6 to 19.2%.…”

Purpose: To summarize the physiology and pathophysiology relevant to perioperative blood loss in children. Strategies to reduce blood losses are reviewed. Methods:The literature was reviewed using the electronic library PUBMED and the Cochrane Database of Systematic Reviews. Relevant studies published in English or French with an English abstract are included. The following keywords were used: children, blood transfusion, surgical blood loss, erythropoietin, autologous blood, red blood cell saver, normovolemic hemodilution, desmopressin, aminocaproic acid, tranexamic acid, aprotinin, cardiac surgery, liver transplantation and scoliosis surgery. Main findings:For patients with idiopathic scoliosis, predonation with or without the addition of erythropoietin is a safe and effective way to avoid the use of allogenic blood products. For open heart procedures: whole blood of less than 48 hr is helpful for children of less than two years of age undergoing complex procedures; tranexamic acid may be helpful for cyanotic heart disease and, to a lesser degree, for reoperations; while antikallikrein blood levels of aprotinin may both reduce the need for allogenic blood transfusions and improve postoperative oxygenation in infants. Conclusion:Reducing perioperative allogenic blood transfusions is possible in pediatric patients provided that prophylactic measures are adapted to age, disease and type of surgery. I N normal children perioperative blood loss leading to administration of allogenic transfusion may be encountered if: the surgical site does not allow easy access to surgical hemostasis, the surgery is performed on highly vascularized tissues that are not easily sutured or cauterized (for example bone elements such as in spinal fusion or correction of craniosynostosis) or the surgery itself induces various disturbances of hemostasis (dilution of factors and induction of fibrinolysis as in cardiac surgery with the use of extracorporeal bypass). The pathology justifying the surgical procedure may also induce various coagulation and/or hemostatic abnormalities. Children suffering from congenital cardiac or liver dis- ease may have thrombocytopenia, abnormal platelet function (congenital heart disease) and/or inadequate amounts of various coagulation factors. Objectif1 Perioperative management of children with congenital coagulation and hemostatic diseases will not be discussed in this review. Developmental aspects of hemostasisAn excellent summary of the developmental physiology of coagulation, based mainly on the extensive work of Maureen Andrew, may be found in a recent review by Kuhle et al. and is summarized in Table I.2 Since maternal coagulation factors do not cross the placental barrier, blood levels measured at birth are the result of fetal synthesis that starts around the fifth week of gestation. Fetal blood becomes clottable around 11 weeks of gestation. Except fetal fibrinogen which has an increased content of sialic acid, all coagulation and inhibitor factors are qualitatively normal at birth, and differ from...

Living-related liver transplantation for patients with fulminant and subfulminant hepatic failure

et al. 1999

The prognosis for patients with fulminant (FHF) or subfulminant hepatic failure (SFHF) has improved since the introduction of liver transplantation. However, the death rate of patients awaiting liver transplantation is high, possibly because of the difficulty in obtaining grafts in a timely manner, given the relative shortage of cadaveric donors. Between June 1990 and June 1999, 106 patients underwent living-related liver transplantation (LRLT) at Shinshu University Hospital. Among them, 8 patients had FHF and 6 had SFHF; these 14 patients are the subjects of this report. The graft volumes (GV) ranged from 231 mL to 625 mL, corresponding to 35% to 105% of the recipients' standard liver volume (SLV). The postoperative courses of all donors were uneventful. Following liver transplantation, all grafts functioned favorably, with normalization of serum total bilirubin within 3 to 5 days and normalization of coagulation profiles within 4 to 7 days. Thirteen of the 14 recipients are still alive. The actuarial 6-month, 1-year, and 5-year survival rates were 100%, 90%, and 90%, respectively. In the present study, when the ratio of the GV to the recipient's SLV was more than 35%, the graft was able to support the patient's metabolic demand after liver transplantation for FHF or SFHF. Because of the urgent nature of liver transplantation in this clinical condition, concerns over informed consent may be even greater than for elective LRLT. Nevertheless, the high success rate and low donor risk may justify this option for pediatric patients, as well as for a limited population of adult patients suffering from FHF or SFHF. (HEPATOLOGY 1999;30:1521-1526.)The prognosis for patients with fulminant hepatic failure (FHF) and subfulminant hepatic failure (SFHF) has improved since the introduction of orthotopic liver transplantation. 1 The survival rate of patients with these conditions who undergo liver transplantation is in the range of 56% to 80%, 2-4 compared with the 15% to 20% survival rate of patients who do not undergo transplantation, even with improved medical treatment. 5 Because FHF is rapidly progressive and irreversible, the need for liver transplantation is urgent. The death rate of patients awaiting liver transplantation is as high as 40% 6 or 62%, 7 possibly as a result of the difficulty of obtaining grafts in a timely manner, given the relative shortage of cadaveric donors.Living-related liver transplantation (LRLT) has been developed as an alternative to cadaveric liver transplantation. To avoid ethical dilemmas in LRLT, including any potential coercion of the live donor candidates, we have pursued a strict policy of ensuring that the participants in LRLT are fully informed of all aspects and risks of the procedure before we obtain their consent. As favorable results for LRLT have accumulated, reluctance toward the procedure has gradually subsided. Given this success, it is worth considering LRLT for patients with FHF, provided that each situation is considered with special care because of the short amount of time...
