Preterm infants undergoing heel blood sampling were randomly allocated to specimen collection by heel puncture (Autolet II Clinisafe) or incision (Tenderfoot 'preemie'). A total of 187 procedures was observed in 47 infants. No significant difference was found in the infants' behavioural response, increase in heart rate, or in the frequency of specimen haemolysis. Collection times for small to medium sized samples were similar, but for large samples (> 1 ml) the Tenderfoot method was superior and fewer repeat procedures were necessary. Tenderfoot has the added advantage of improved safety, but it is too costly for routine use.
接受足跟采血的早产儿被随机分配采用足跟穿刺（Autolet II Clinisafe）或切开（Tenderfoot “preemie”）进行标本采集。共对47名婴儿进行了187次操作。在婴儿的行为反应、心率增加或标本溶血频率方面未发现显著差异。中小样本的采集时间相似，但对于大样本（>1 ml），Tenderfoot方法更具优势，且重复操作较少。Tenderfoot的额外优势是安全性提高，但常规使用成本过高。
