Raynaud’s phenomenon during anesthesia recovery period: a case report

This case report revealed that Raynaud's phenomenon happened during anesthesia recovery period and caused panic. We performed general anesthesia for a patient who underwent laparoscopic nephrectomy and denied any signifi cant medical history. After surgery, just when the patient started breathing, we noticed that the displayed waveform and numerical values of SpO2 disappeared suddenly. No problems were detected in the monitor and the ventilator. On auscultation, both lungs were being ventilated well. Severe complications were suspected which led to tense and panic. The patient was extubated later, and she confirmed that she had primary Raynaud's for 6 years. The patient was transferred to the recovery room later, and then her ward uneventfully. It is important to know the whole medical history of patients'. The attack of Raynaud's phenomenon can make the displayed waveform and numerical values of SpO2 disappear suddenly.
