A review of blood transfusions in a trauma unit for young children

Background. Trauma is the leading cause of mortality and morbidity worldwide. Blood transfusions play an incremental role in the acute phase, yet practice varies owing to variations in transfusion thresholds and concerns about potential complications, especially in children.Objectives. To evaluate protocol adherence to blood transfusion thresholds in paediatric trauma patients and determine the degree of blood product wastage, as defined by discarded units.Methods. A retrospective, descriptive study of trauma patients (age 0 - 13 years) who received a blood transfusion in the trauma unit at Red Cross War Memorial Children's Hospital, Cape Town, South Africa, over a 5.5-year period (1 January 2009 - 1 July 2014). Haemoglobin (Hb) transfusion thresholds were defined as 10 g/dL for neurotrauma patients and patients requiring skin grafting or a musculocutaneous flap (group 1). All other trauma patients had an Hb transfusion threshold of 7 g/dL (group 2).Results. A total of 144 patients were included (mean age 5.2 years (standard deviation (SD) 3.3), 68.1% male). The mean Hb increase after transfusion was 3.5 g/dL (SD 1.7). Adherence to the transfusion Hb threshold protocol was 96.7% for group 1 v. 34.0% for group 2. No complications were reported. Average blood wastage was 3.5 units per year during the study period.Conclusions. Adherence to paediatric blood transfusion protocol was low in the Hb threshold group <7 g/dL. However, transfusion-related complications and wastage were minimal. Further prospective research is required to determine optimal blood transfusion guidelines for paediatric trauma patients

Nephron-sparing surgery for bilateral wilms' tumours: a single-centre experience with 23 cases

Introduction: The challenge of management with bilateral Wilms' tumours is the eradication of the neoplasm; while at the same time preserving renal function. Surgical management with a variety of nephron-sparing techniques; combined with chemotherapy and occasionally supplemented by transplantation has evolved over the last 30 years to achieve remarkable success. We document the experience of a single centre in a developing country. Material and Methods: Twenty-three bilateral Wilms' tumours were seen in our service between 1981 and 2007. Treatment was; in most cases; according to National Wilms' Tumour Study Group protocols; with initial bilateral biopsy; neoadjuvant chemotherapy; and tumourectomy. Technique of nephrectomy included full mobilization of the tumour-involved kidney; topical cooling with slush ice; vascular exclusion; tumour resection and reconstruction of the remnant kidney. Results: Twelve patients are alive and free of disease one to 15 years after treatment; all with well-preserved renal function (lowest glomerular filtration rate was 65 ml/min per (1.73 m 2 ). None of the survivors have hypertension. Eleven have died (two of unrelated disease) including six of the seven with spread outside the kidney. All three with unfavourable histology are alive. Four of the five metachronous presentations are alive; as are eight of 12 patients with synchronous bilateral tumours who presented since 2000. Conclusions: Appropriate chemotherapy and nephron-sparing surgery can achieve good results with preservation of adequate renal function in nearly all cases. Unfavourable histology did not have a reduced survival in our series. Metastatic spread outside the kidney had a poor prognosis
