Patient-controlled analgesia

It has become increasingly obvious that traditional narcotic dosage schemes are not optimally effective in relieving pain. Inadequate relief of pain results in increased patient morbidity, probably due to adverse effects on the neurologic, endocrine, pulmonary and cardiovascular systems. Insufficient pain relief also contributes to patient dissatisfaction. Patient-controlled analgesia allows a patient to balance analgesic levels with the degree of pain relief required. This analgesic technique is easy to use and is well accepted by patients, physicians and nurses. Significant benefits include earlier ambulation, decreased overall narcotic use, improved postoperative pulmonary function, shorter hospital stay and reduced health care costs.
