Comparison of Non-Disposable and disposable Oximeter Probes During Anesthesia Induction

Allysa Adkins CRTT, Jon A. Tucker CRTT, and Bryce Click CRTT

BACKGROUND: To manage costs, we compared the performance of disposable versus non-disposable oximeter probes in the surgical setting. We compared performance of two Nellcor oximeter probes during anesthesia induction, and compared those to the currently used disposable probe. Noninvasive measurement of oxyhemoglobin saturation by pulse oximetry (SpO2) has become one of one most important monitoring advances in the care of anesthetized and seriously ill patients, and its used is the accepted standard of care intraoperatively. We hypothesized that the accuracy, precision, and performance of the reusable (non-disposable) probe will be comparative to that of the currently used Nellcor probe and provide a cost savings. MATERIALS AND Methods: Children receiving general anesthesia and are greater than one year of age were incorporated into our study. Nellcor Oxiband and Dura-Y reusable probes were each attached to a separate pulse oximeter, and placed simultaneously in the same vicinity of the same extremity of each patient with the disposable probe. A foam and a band- aid type wrap were alternated throughout the study. SpO2 and heart rate measurements were taken at one minute intervals for the first ten minutes of anesthesia induction. Waveform consistency and motion artifact were also obtained. The results of the disposable probe were compared to the results of the non-disposable probe by a one-way ANOVA. Results: We found that there was no statistical difference between the mean heart rates or the mean saturations using the Dura-Y oximeter probe. There was no statistical difference between the mean heart rates with the Oxiband oximeter probe. There was a significant statistical difference between the mean saturations with the Oxiband probe.

Conclusions: Due to the significant statistical difference with the Oxiband probe. using the Dura-Y probe may be a more reasonable choice. From all of all data. we can conclude that the Dura-Y reusable oximeter probe demonstrates comparative performance to the disposable N-25 probe. We believe that reusable probes are reliable in the OR setting and represent a substantial cost saving for the hospital.
