Withholding Feeds During Red Blood Cell Transfusion and TRAGI (Tx-TRAGI)

The Effect of Withholding Feeds During Red Blood Cell Transfusion on Development of TRAGI in Very Low Birth Weight Infants

Necrotising enterocolitis (NEC) is a devastating picture that all the neonatologists are afraid of facing during the follow up of newborns. During the last years, investigators ran retrospective observational studies abut NEC developing within the 48 hours after red blood cell transfusion. In the previous studies, the incidence of transfusion associated NEC (TANEC) was found to be 20-35%.Multiple transfusions potentially cause an increased risk for retinopathy of prematurity (ROP) and NEC. Investigators have also proposed a hypothesis about transfusion related acute gut injury (TRAGI), an adverse reaction of transfusion, similar to transfusion related acute lung injury (TRALI) seen in adults.In most of the neonatology clinics, withholding feeds during transfusion is not preferred. But several recent studies show an increase in the incidence of TANEC if the newborn goes on feeding before, during and after the transfusion process, especially if it is fed with a formula. The main aim of this study is to investigate the effect of withholding feeds during transfusion, on the development of TRAGI.

Transfusion, Feeding During Transfusion, Transfusion Related Acute Gut Injury, Necrotising Enterocolitis

At least 2 feeds before the transfusion, 2 feeds after the transfusion and feeds during the transfusion are withholded

At least 2 feeds before the transfusion, 2 feeds after the transfusion and feeds during the transfusion are withholded

Bell's stage 1/Suspected disease: Mild systemic disease (apnoea, bradycardia, temperature instability) Mild intestinal signs (abdominal distention, gastric residuals, bloody stools) Non-specific or normal radiological signs Bell's stage 2/Definite disease: Mild to moderate systemic signs Additional intestinal signs (absent bowel sounds, abdominal tenderness) Specific radiologic signs (pneumatosis intestinalis or portal venous air) Laboratory changes (metabolic acidosis, thrombocytopaenia) Bell's stage 3/Advanced disease: Severe systemic illness (hypotension) Additional intestinal signs (striking abdominal distention, peritonitis) Severe radiologic signs (pneumoperitoneum) Additional laboratory changes (metabolic and respiratory acidosis, disseminated intravascular coagulation)

within 3 days after transfusion but participants will be followed for the duration of hospital stay, an expected average of 5 weeks
