Abstract

An optical surgical navigation system is used as a navigator to facilitate surgical approaches, and pulse oximeters provide valuable information for anesthetic management. However, saw-tooth waves on the monitor of a pulse oximeter and the inability of the pulse oximeter to accurately record the saturation of a percutaneous artery were observed when a surgeon started an optical navigation system. The current case is thought to be the first report of this navigation system interfering with pulse oximetry. The causes of pulse jamming and how to manage an optical navigation system are discussed.

Highlights

The Polaris spectra optical measurement system (NDI, Waterloo, Canada) is a surgical navigation system used for CT-guided stereotaxic neurosurgery
While a pulse oximeter is an essential monitor for anesthesia management, the malfunction of a pulse oximeter was observed several times during general anesthesia management of neurosurgery, and it was determined that it resulted from the navigation system, and a way to manage the problem was developed

Summary

Introduction

Background The Polaris spectra optical measurement system (NDI, Waterloo, Canada) is a surgical navigation system used for CT-guided stereotaxic neurosurgery. The surgeon set up the Polaris spectra optical measurement system, and the pulse oximeter (NIHON KOHDEN, Tokyo, Japan) showed different values for oxygen saturation (SpO2) and pulse rate on its display. * Correspondence: anemasa@jichi.ac.jp 1Department of Anesthesiology and Critical Care Medicine, Jichi Medical University, Yakushiji, Shimotsuke-City, Tochigi 329-0498, Japan Full list of author information is available at the end of the article example, the value of SpO2 changed from 99 to 94 % and from 94 to 100 %.
