ABSTRACT
There have been several new cardioplegia delivery systems that have been developed by various manufacturers in the last few years. In this evaluation, the safety and costs associated with the present 4:1 roller pump cardioplegia delivery were compared to the Medtronic Cardioplegia Safety System Trademark (CSS Trademark). One hundred and five patients participated in a randomized, prospective evaluation. The current cardioplegia delivery system consists of using the 4:1-B MYOtherm XP Trademark disposable by Avecor Cardiovascular and a Sarns Trademark MDX 7000 roller pump. The Medtronic Cardiotherm Trademark disposable cardioplegia unit was used in conjunction with the CSS Trademark. The current delivery system will be referred to as group A and the system under evaluation will be referred to as group B. Two varying techniques are employed for cardioplegia delivery and are based on surgeon preference. An equal distribution of techniques was seen in both groups. Results indicated that in group A, a hemoconcentrator was required 60.3% of the time, whereas in group B, a hemoconcentrator was added only 25.0% of the time. The average total cardioplegia delivered in group A was 6588 cm[sup 3] compared to 7123 cm[sup 3] in group B. Although this is insignificant, the greatest difference was seen in the amount of crystalloid given. In group A, the crystalloid portion was 1317 cm[sup 3] compared to only 877 cm[sup 3] in group B. There was equal weight gain and hemodilution postop in both groups. Twenty-five incidences of pressurization of the cardioplegia system occurred during the evaluation, with equal distribution in both groups. This evaluation showed that the CSS Trademark responded without fail to all pressurization incidences. The Medtronic CSS Trademark has incorporated several safety systems for pressurization and air embolism protection, which are programmable and preset by the perfusionist. The Avecor disposable has a pressurization valve that activates at a pre...
