ABSTRACT

Patient-controlled analgesia (PCA) is a popular and efficacious form of postoperative pain relief that, however, is not without complications. Here we describe a 73-year-old Somalian male patient that underwent abdominal surgery and received intravenous morphine PCA for postoperative pain relief. Due to his inability to speak the native language, his son served as interpreter. On the day after surgery, the patient was found unresponsive by the nursing staff with an oxygen saturation of 91%. He was treated with naloxone and transferred to a medium care facility. The son indicated that he had operated the PCA system at regular intervals over the last 12 hours. The dangers of PCA and PCA by proxy in particular are discussed. In this case, the language barrier, and possibly cultural differences and health illiteracy may have contributed to the PCA by proxy.
