Randomized Controlled Trial Comparative Study
Use of a large bore syringe creates significantly fewer high intensity transient signals (HITS) into a cardiopulmonary bypass system than a small bore syringe.
High intensity transient signals (HITS) have been reported to occur following perfusionist intervention during cardiac surgery. This study investigates the relationship of the syringe bore, injection rate, and HITS created. ⋯ Significantly fewer HITS are introduced into the CPB system by using standard syringes and slower injection time.
