We successfully performed L2.3 epidural puncture in the lumbar space and equipped her with a self-controlled epidural analgesia infusion pump (100mL, 10mL 1% ropivacaine + 50ug sufentanil + 89mL normal saline) with a load of 8mL for continuous delivery. Continuous infusion of 8mL/h, patient controlled analgesia (PCA) 6 mL/ time at 15 minute intervals. The analgesic effect is good. In the following 40 minutes or so, due to fetal monitoring, fetal heart rate variation deceleration accompanied by late deceleration, the minimum was reduced to 85 times/min, and there was no improvement after treatment, and then the obstetrician prepared to perform an emergency cesarean section. The anesthesiologist evaluated the patient and then chose an epidural. The epidural dose was 3mL 1% lidocaine +0.5% rox mixture, and 7mL 1% lidocaine +0.5% rox mixture was administered 3 minutes later. During the administration, the patient complained of unbearable headache and rapid loss of consciousness. Immediate organization rescue, uterine dissection, pressure oxygen, preparation of tracheal intubation, cardiopulmonary resuscitation, cardiovascular active drugs, etc. After about 1 minute, the patient regained consciousness, responded smoothly, the vital signs were stable, the anesthesia plane T8 was measured. The patient’s surgery went smoothly, and there were no complications during postoperative follow-up. They were discharged 5 days later. Such cases are relatively rare, especially during cesarean section surgery has not been reported, so it is published for everyone’s reference.Keywords: labor analgesia, caesarean section, transient consciousness disorder
