To determine the perinatal outcome of pregnancies complicated by Rh-alloimmunisation, requiring intrauterine blood transfusion. Observational study. Feto-maternal Unit of Gene Tech Laboratory, Lahore, from 2007 to 2019. A retrospective analysis was done on the data of cases of intrauterine, intravascular blood transfusion given to at-risk foetuses to correct foetal anaemia due to Rh-alloimmunisation or parvovirus B19. All cases, who were eligible to receive IUBT were included in the study. Cases where historic data was not available have been excluded. A total of 305 intrauterine blood transfusion (IUBT) procedures were performed on 127 foetuses. The gestational age ranged from 18-32 weeks at the time of referral. Infra-hepatic part of umbilical vein was preferred for transfusion, but in some cases of anterior placenta, the cord insertion was approached with exception of only two cases where intra-cardiac route was employed. In this study, 71.6% of the babies survived, 14.2% were loss to follow and 14.2% died. IUBT is a safe procedure, especially when performed by experienced hands, and helps save the foetuses at risk. Mothers with Rh-alloimmunisation should be referred before developing hydrops fetalis for better outcome. Key Words: Red cell alloimmunisation, Intrauterine intravascular blood transfusion, Foetal anaemia.
