Study of adverse whole blood donor reactions in normal healthy blood donors: experience of tertiary health care centre in jammu region.

Whole blood donation is generally a safe procedure, but sometimes adverse reactions of varying severity may occur during or at completion of blood donation process. The aim of the present study was to estimate the frequency and type of adverse events during blood donation. This retrospective study conducted from November 2011 to December 2012 at Department of Blood Transfusion Medicine GMC Jammu. All whole blood donations at our Department was analyzed. All adverse events occurring during or at end of donation were noted using standardized format. Overall 108 adverse events were reported in relation to 29,524 donations, resulting in overall adverse event rate of 0.365 %. Presyncopal reactions in other words vasovagal reactions of mild intensity, were the most commonly observed adverse reactions and accounted for approximately 58/108 (53.70 %) of all adverse reactions noted. Only 0.365 % of blood donations were complicated by adverse events and most of these events were presyncopal symptoms. Our study reinforces that blood donation is a very safe procedure which could be made even more event free by following certain friendly, reassuring and tactful practices.
