Preoperative Transfusion in Sickle Cell Disease Children Undergoing Adenotonsillectomy.

Objective: To perform a systematic review and meta-analysis comparing two pre-operative transfusion regimens (conservative versus aggressive) in children with sickle cell disease(SCD) undergoing adenotonsillectomy in terms of post-operative complications, complications related to SCD and transfusion related complications.

Data Sources And Review Methods: A literature review was performed through PubMed, EMBASE, Cochrane, and Ovid databases using the following phrases: (Adenotonsillectomy OR Tonsillectomy) AND (Sickle Cell Disease OR Sickle Cell Trait). Using predetermined inclusion and exclusion criteria, seven articles were selected for systemic review and two control trials were included in meta-analysis.
