Randomized Controlled Trial Comparative Study
A prospective randomized trial of nebulized morphine compared with patient-controlled analgesia morphine in the management of acute thoracic pain.
Successfully managing pain for the trauma patient decreases morbidity, improves patient satisfaction, and is an essential component of critical care. Using patient-controlled analgesia (PCA) morphine to control pain may be complicated by concerns of respiratory depression, hemodynamic instability, addiction, urinary retention, and drug-induced ileus. Morphine is rapidly absorbed by mucosal surfaces in the respiratory tract, achieving systemic concentrations equal to 20% of equivalent intravenous doses. The purpose of this study was to evaluate the safety, efficacy, and utility of nebulized morphine in patients with posttraumatic thoracic pain. ⋯ Nebulized morphine can be safely and effectively used to control posttraumatic thoracic pain. Pain can be successfully managed while vital capacity, mean forced expiratory volume in one second, and spirometric volumes are maintained. Compared with PCA morphine, nebulized morphine provides equivalent pain relief with less sedative effects.
