IntroductionHomozygous sickle cell carriers have an increased perioperative mortality. Some indications may justify an exchange blood transfusion to reduce the proportion of haemoglobin S. The advantages of general blood transfusion in a perioperative setting have not been proven and thus remain controversial. It is not clear whether reducing the proportion of haemoglobin S minimizes perioperative complications or whether patients with sickle cell disease in a stable clinical condition benefit from an exchange blood transfusion in a perioperative setting.Case PresentationWe report the case of two Angolan children aged 10 and 11 respectively, of African origin with sickle cell anaemia who underwent surgery to treat chronic necrosis, fistula of the bones and bone destruction. This presentation describes the perioperative course, including general anaesthesia. A partial exchange blood transfusion decreased S-haemoglobin levels from 81% to 21% and simultaneously treated the anaemia.ConclusionThere is a consensus that imbalances in homoeostasis, including operative procedures, can cause a critical exacerbation of sickle cell disease. The case presented here illustrates a strategy for successfully managing sickle cell disease in the perioperative period to minimize its complications. It is important for the anaesthesiologist to carefully manage pulmonary gas exchange and to ensure sufficient tissue perfusion, balanced fluid resuscitation and normothermia, while keeping in mind the level of organ impairment in order to prevent an acute exacerbation of sickle cell disease.We performed a partial exchange blood transfusion due to the following factors: high haemoglobin S-fraction, anaemia, operating procedure at several sites, and difficult management of body temperature. Esmarch ischemia is an established tool for preventing uncontrolled blood loss. There is no known contraindication for this, but attention must be paid to prevent uncontrolled tissue ischemia and acidosis. The use of regional anaesthesia should be considered for postoperative pain management.
