An elective knee arthroscopy was planned for a 20-year-old female athlete.
Only the history of fainting was remarkable in the medical history. At the
L4-5 interspace, a spinal anaesthetic containing 60 mg lidocaine 2 percent
plain was administered. The patient chose to watch the video display
instead of being sedated and stayed fully awake. The patient began to feel
nauseous thirty minutes after the spinal was injected. Her heart rate had
dropped to 28 beats per minute from 50 beats per minute at the start. The
patient went into asystole all of a sudden. Despite positive pressure
ventilation and 100% oxygen supplied via a mask, she soon became
cyanotic.
