Population
Rh(D) alloimmunised pregnant women (15 studies).
Intervention
Systematic review and meta-analysis to determine the effectiveness and safety of intrauterine transfusions (IUTs).
Comparison
Outcome
The forest plots all showed statistically significant outcomes with heterogeneity of data. Results indicated a greater foetal survival rate with IUT to treat anaemic foetuses, a low foetal mortality rate, and low risk of procedure-related complications associated with foetal loss but a higher risk of foetal mortality when hydrops is present.
