Electrical devices used in the clinical setting can induce artifacts by various different mechanisms. We aimed to present an example of serious artifact happened during induction of general anesthesia in a child. With the advent of newer surgical technologies and more advanced anesthesia and surgical equipment in the operating room, we are expecting the interference could be an issue, if it is not taken into considerations in advance. Healthcare provider should be aware about this incident and its management. Electronic patient record is now a standard of care in the operating room, the intensive care unit (ICU) and other departments in many hospitals. Artifactual signals, which could corrupt the normal electronic recordings, may arise from external sources. Electrical devices used in the clinical setting can induce artifacts by various different mechanisms. Newer diagnostic and therapeutic modalities may unpredictably generate few but significant artifactual changes. These artifacts may be nonspecific or may resemble serious complication in terms of adding or removing new parameters or new drugs, and closing or opening some new windows when using anesthesia management software “Cerner electronic system”. Technological advancements in processing the electrocardiographic (ECG) signals may be useful to detect and eliminate machine artifacts. Ultimately, understanding of the artifacts generated by devices, and their identifying characteristics, is important to avoid misinterpretation, misdiagnosis, and unpredictable complications. Here we present an example of such unexpected artifact in anesthesia charting software that appeared during maintenance of general anesthesia in a child.
