Abstract

BACKGROUND: The most serious complication of patient-controlled analgesia (PCA) is respiratory depression (RD). The incidence of RD in the literature is derived from intermittent sampling of pulse oximetry (Spo(2)) and respiratory rate and defined as a deviation below an arbitrary threshold. METHODS: We monitored postsurgical patients in a hospital ward receiving morphine or meperidine PCA with continuous oximetry and capnography. Nurses responding to audible monitor bedside alarms documented respiratory status and interventions. RESULTS: A total of 178 patients were included in the analysis, 12% and 41% of whom had episodes of desaturation (Spo(2)
