[Introduction of a simple audio recording system to the operating room--experience at a small local hospital].

We developed a simple audio recording system using a small personal computer and free audio recording software that makes voice recordings for use in emergencies, particularly for emergency caesarean sections. The system makes a continuous audio recording while the patient receives medical treatment. The recording provides an accurate record of the anesthesia used during treatment. This audio recording system is useful as an auxiliary means of record keeping during medical emergencies.
