The Effectiveness Of Pre-Donation Water Hydration In Reducing Vasovagal Reaction And Its Risk Factors Among Young Blood Donors In Kelantan.
Masters thesis, Universiti Sains Malaysia.
Abstract
Background: Vasovagal Reaction (VVR) is the commonest adverse reaction that occurred
among blood donors worldwide. It has negative effect towards donor retention. Therefore it is
important to reduce the VVR incidence. The aim of this study was to determine the effectiveness
of pre-donation water hydration in reducing VVR among young blood donors in Kelantan.
Methods: A quasi experimental study was performed among blood donors in Kelantan who
donate blood in blood drives conducted by Transfusion Medicine Unit, Hospital Universiti Sains
Malaysia (HUSM) over a period of eight months. A total of 284 young blood donors age from 17
to 23 years old, were assigned equally into two groups, hydration and non hydration group.
Donors then were assessed with BDRI 4-Items at 30 minutes and 48 hours post blood donation.
Results: The incidence of VVR among young blood donors in this study was 25.4%. Statistically,
a hydration group showed significantly lower VVR incidence compared to non hydration group
(1.5% vs. 32.5%)(p value = 0.0001). Younger age, lower weight, lower estimated blood volumes
were associated with VVR incidence. The mean BDRI score at 30 minutes and at 48 hours were
significantly lower in hydration group compared to non hydration group. BDRI 4-Items score at
30 minutes and at 48 hours showed positive correlation only in non hydration group.
Conclusions: This study showed that pre-donation water hydration was effective in reducing
VVR incidence among young blood donors in Kelantan.
