Patient Controlled analgesia (PCA) has become accepted as an important means of self regulated relief from post surgical pain. In commonly used PCA systems, patients use a hand held push button to indicate the presence of pain and initiate a predetermined bolus of drug infusion. A disadvantage of this system is that no means is provided to accommodate variations in the intensity of pain or the sensitivity of the patient to the analgesic in use. The PCA system described in this paper uses a specially designed handset which allows the patient to indicate pain intensity and so vary the level of the drug infusion. Data derived from the handset signals provides a basis for adapting the drug dosage to patient sensitivity as well as pain intensity. In addition a capnograp h and oximeter provide direct monitoring of the patient's state and allow for a larger range of adaption. |
