A Study of Naloxone Effect on Urinary Retention in the Patient Receiving Morphine Patient-Controlled Analgesia

Abstract

Postoperative urinary residuals were lower, patients voided more frequently, and fewer catheterizations were needed when given low-dose naloxone while receiving morphine patient-controlled analgesia. At the same time, naloxone in small doses was found to have negligible effect on overall patient pain control.
