Introduction. Renal failure and control nervous system (CNS) events are causes of morbidity after open-heart surgery (OHS). The objective of this pilot study was to evaluate the incidence of renal failure and postoperative CNS events after OHS.

Methods. Fifty-four patients were monitored intraoperatively using the INVOS 4100 cerebral oximeter; readings were maintained at levels of 40 or greater. Interventions used to increase INVOS readings included increased pump flow, elevated perfusion pressures, augmenting CO2 levels, and transfusions. The study group was compared with 1,131 patients operated on in the prior year who did not have INVOS monitoring. The demographics of both groups were similar.

Results. STS database criteria were used to determine the incidence of renal failure and CNS complications, shown below with mortality and length of stay.

Interventions required to elevate the INVOS readings were surprisingly frequent (>50%). Low readings were relatively easy to correct. The absence of CNS and renal problems was reflected in reduced postoperative length of stay (LOS).

Conclusions. These findings suggest that unappreciated hypoxia reflected in renal and CNS dysfunction may be responsible for morbidity that is preventable, resulting in reduced LOS.
