ADVERSE DONOR REACTION PATTERN IN A TERTIARY CARE BLOOD CENTER IN SOUTH INDIA

Abstract

Aims & Objective Primary objective is to assess the frequency and pattern of donor reaction in our blood center and secondary objective is to assess the factors associated with vaso-vagal reaction (VVR). Materials & Methods Retrospective observational study conducted by Blood Center of Sree Gokulam Medical College, Trivandrum. Details of the donors of the last 4 year (January 2015 to December 2019) including donor reaction details, age, gender, weight, donation status, type of donation and Blood Pressure(BP) were included in the study and were analyzed using IBM SPSS Version 21 Results & Discussion Out of 10,647 donors, the overall donor reaction rate is 1% while in-house and camps reaction rate were 0.96% and 3.49%. Donor reaction rate in males and females were 0.99% and 1.03%. Out of 105 reactions, 70.75 % were VVR and 19 % were Hematoma. VVR rate is 0.74. Most common VVR occurred was mild type. Young age, first time donation and voluntary donation were found to be predisposing factor for VVR. VVR rate was not associated with gender, weight and Blood Pressure (BP) of the donor. VVR in post donation phase was associated with low BP and severe VVR was not associated with low BP. Conclusion Overall reaction rate and VVR rate were 1.0% and 0.74%. Young age, first time donation and voluntary donation were found to be predisposing factor for VVR. It is important to contact donors to report any missed delayed reaction.
