ABSTRACT:
An automatic, computer-controlled, closed-loop system administers pulsed doses of medication to patients. One application of the system is for administering oxytocin to women in labor. Once initial, preprogrammed doses of oxytocin are delivered, feedback signals from the patient are processed by a microcomputer. Those signals correspond to changing patterns of intrauterine contractions. In response to the feedback signals, the microcomputer controls the infusion of oxytocin by a pump and varies the size of the pulsed doses. The microcomputer also detects undesirable or emergency conditions from the signals, makes adjustments, and relates that information to the doctor. A display shows intrauterine pressure and relays information announcing the beginning and the end of contractions. The closed-loop system induces labor more efficiently than existing systems while using lower doses of oxytocin.
