While there are many reasons people choose not to donate blood, pain sustained during the venipuncture portion of the blood donation process is likely one deterrent to volunteer donation. The purpose of this study was to survey the improvement in likelihood of donation if participants were given the option of a topical anesthetic cream prior to venipuncture.
Over a three month period 316 adults (convenience sample) completed a one page survey consisting of twelve questions pertaining to blood donation. Participants were asked about their likelihood of donating blood in the near future (No Possibility, Possible, Likely, Certain). They were then informed of the possibility of using a topical anesthetic cream prior to donation. Subsequently, their likelihood of donating blood was reassessed.
Fifty (16%) subjects reported an increased likelihood of donating blood if offered a topical anesthetic (p〈0.0001). Of these respondents reporting an increase in donation likelihood, eleven improved by 2 or more likelihood categories. Amongst the 169 participants who never donated blood, 34 (20%) reported an increased likelihood of donation after being told about the topical anesthetic cream, compared to 16 (10%) of the 147 subjects who had previously donated blood (p=0.02).
The findings of this study suggest that providing a topical anesthetic had a positive effect on the study participants' likelihood of donating blood. This improvement was greater amongst those who have never donated blood.
虽然人们不献血有很多原因，但献血过程中静脉穿刺时的疼痛可能是阻碍自愿献血的一个因素。本研究的目的是调查如果在静脉穿刺前为参与者提供外用麻醉乳膏，献血可能性的改善情况。
在三个月的时间里，316名成年人（便利样本）完成了一份包含12个与献血相关问题的单页调查问卷。参与者被问及他们在不久的将来献血的可能性（不可能、有可能、很可能、肯定）。然后告知他们在献血前使用外用麻醉乳膏的可能性。随后，重新评估他们献血的可能性。
50名（16%）受试者表示，如果提供外用麻醉剂，他们献血的可能性会增加（p〈0.0001）。在这些报告献血可能性增加的受访者中，11人提高了2个或更多的可能性类别。在169名从未献血的参与者中，34名（20%）在被告知外用麻醉乳膏后报告献血可能性增加，而在147名曾献血的受试者中，有16名（10%）报告献血可能性增加（p = 0.02）。
本研究结果表明，提供外用麻醉剂对研究参与者的献血可能性有积极影响。这种改善在从未献血的人群中更大。
