Although the final number of subjects recruited into the trial at its termination was small, the TAPS study provided good evidence to support preoperative transfusion in SS patients undergoing low‐ and medium‐risk surgical procedures. But these procedures are not without risk. Copyright © 2013-2020 All rights reserved.

The study by Howard et al (1995) demonstrated a trend for reduced SCD‐related complications in the third trimester in patients on prophylactic exchange transfusions, leading the authors to recommend prophylactic transfusions from the 26th week of pregnancy onwards in SS patients.

Always seek the advice of your physician or other qualified health provider with any questions you may have regarding a medical condition. The TAPS trial has provided evidence for the efficacy of preoperative transfusion only for SS patients with preoperative Hb 60–90 g/l undergoing a narrow range of elective medium‐risk surgical procedures (Howard et al, 2013).

Complicated surgical procedures should be undertaken in centres where there is specialist haemoglobinopathy support. Chronic blood exchange transfusions in the management of pre-capillary pulmonary hypertension complicating sickle cell disease. Another study showed that those receiving “no transfusion” suffered the highest overall SCD‐related complication rate (32%), chest syndrome rate (19%) and mortality rate (5%) but without significant difference between those randomised to aggressive or simple transfusion regimens (Haberkern et al, 1997). Automated RBC exchange compared to manual exchange transfusion for children with sickle cell disease is cost‐effective and reduces iron overload. ASH also suggests that pregnant women receive blood transfusions in accordance with standard-of care-guidelines. We are indebted to Dr Alison Thomas for reviewing the manuscript.

Impact of Red Blood Cell Antigen Matching on Alloimmunization and Transfusion Complications in Patients with Sickle Cell Disease: A Systematic Review, Successful Treatment of Acute Chest Syndrome with Manual Exchange Transfusion in a Patient with Sickle Beta. In a UK‐wide observational study of 109 pregnancies in SCD, 52% of women suffered painful crises during pregnancy and 13% within 6 weeks post‐partum; 6% had ACS and 21% were admitted to intensive care (Oteng‐Ntim et al, 2015a). Transfusion Management of Patients With Sickle Cell Disease and Thalassemia. The guidelines also recommend additional screenings to assess iron levels in SCD patients requiring chronic transfusions. Fetal complications include intra‐uterine growth restriction, prematurity and increased rates of fetal loss (Serjeant et al, 2004; Oteng‐Ntim et al, 2015b). Adverse outcome of acute splenic sequestration crisis in pregnancy. All authors were involved in reviewing evidence and writing the paper. “ASH believes it is essential to provide updated treatment guidelines that reflect this increased knowledge and can help the medical community better treat SCD.”. The post‐transfusion Hb can be set at a higher target in chronically transfused patients or if %HbS is low, but should be individualised to each patient. In the largest study on surgery in SCD, 717 patients underwent 1079 surgical procedures of which 271 (25%) were emergency procedures (Koshy et al, 1995).

The guidelines were described in the study, “American Society of Hematology 2020 guidelines for sickle cell disease: transfusion support,” published in the peer-reviewed journal Blood Advances. joint replacement, cholecystectomy, tonsillectomy) were randomly assigned to either no transfusion or transfusion (simple transfusion if Hb <90 g/l, exchange transfusion if Hb ≥90 g/l to achieve estimated HbS <60%) (Howard et al, 2013). It should be emphasised that pregnancy in women with SCD is high‐risk and expert obstetric care is essential to achieving good outcomes. Other, comprises haemoglobin S/hereditary persistence of fetal haemoglobin, haemoglobin S/haemoglobin Lepore and haemoglobin S/haemoglobin O‐Arab. A Cochrane review which examined evidence from two small studies of low quality concluded that other than a marginal reduction in the rate of painful crises, prophylactic transfusion conferred no clear advantage over selective transfusion with regards to pregnancy outcome (Okusanya & Oladapo, 2013). Additionally, satisfactory pregnancy outcomes were observed in a non‐randomised group of SS, SC and S/β thalassaemia women who were transfused only for medical or obstetric emergencies. However, on the basis of the findings, it is recommended that preoperative transfusion to an Hb of 100 g/l be considered a standard intervention in SS undergoing elective low‐risk or medium‐risk surgery as defined in the study (Howard et al, 2013). One observational study suggested a benefit for transfusion in reducing the incidence of sickle cell‐related postoperative complications for SC patients at all levels of surgical risk (Koshy et al, 1995), however, transfused SC patients undergoing low‐risk surgery had higher rates of non‐sickle cell postoperative complications (fever and bleeding) than untransfused patients. In a more recent retrospective study, high rates of painful sickle crises and other severe sickle complications occurred despite a policy of prophylactic partial exchange transfusions to maintain HbS <40% from 22 to 26 weeks onwards for all sickle patients (Ngo et al, 2010), but there was no control arm not receiving prophylactic transfusion for comparison. “We’ve also provided best practices and tips for patients and caregivers to help inform conversations with their healthcare providers,” Chou said. Alteration of humoral, cellular and cytokine immune response to inactivated influenza vaccine in patients with Sickle Cell Disease. The panel said most of its recommendations are “conditional,” as in many cases, there isn’t much available evidence regarding “outcomes of interest.”.
