A cross-over study carried out over a 24 week period during 1975-76 was designed to test the relative merits of Extracorporeal versus Travenol coils for thrice weekly short periods of haemodialysis for patients with end-stage renal failure. Predictability of and capacity for ultrafiltration were excellent and equally good for both products. Leak rates in Travenol coils were 9.3% as compared to 4.3% for Extracorporeal coils. Dialysances of BUN, creatinine, and phosphate were significantly higher with Travenol coils than with Extracorporeal coils, but this increase was not as great as might be expected from the greater surface area of the Travenol coil. Despite the greater functional efficiency of the Travenol coils we could detect no difference in the degree of biochemical control of the patients as judged by standard pre and post dialysis blood chemistries. Residual blood volumes averaged 9 mls for the Travenol coils as compared to 1.6 mls for Extracorporeal coils.
一项在1975年至1976年期间进行的为期24周的交叉研究，旨在测试体外线圈与特拉文诺尔线圈对于终末期肾衰竭患者每周三次短时间血液透析的相对优点。两种产品的超滤可预测性和超滤能力都非常出色且相当。特拉文诺尔线圈的泄漏率为9.3%，而体外线圈为4.3%。特拉文诺尔线圈对尿素氮、肌酐和磷酸盐的透析率显著高于体外线圈，但这种增加并不像根据特拉文诺尔线圈更大的表面积所预期的那么大。尽管特拉文诺尔线圈的功能效率更高，但根据透析前后的标准血液化学指标判断，我们未发现患者的生化控制程度有差异。特拉文诺尔线圈的残余血量平均为9毫升，而体外线圈为1.6毫升。
