Randomized Controlled Trial Comparative Study Clinical Trial
Prospective evaluation of epidural and intravenous administration of fentanyl for pain control and restoration of ventilatory function following multiple rib fractures.
To evaluate the efficacy of opiate administration regimens, 32 patients with multiple rib fractures were prospectively randomized to receive either continuous epidural (ED) or continuous intravenous (IV) infusions of fentanyl. Dosage was titrated to individual subjective pain relief. Ventilatory function tests (VFTs), arterial blood gases (ABGs), and visual analog scores were obtained before and after the institution of analgesia. ⋯ Side effects were similar between the groups, with pruritus being more pronounced with ED fentanyl administration. The data demonstrate that the continuous ED fentanyl method offers excellent relief of pain and improvement in ventilatory function and has distinct advantages over IV fentanyl administration with respect to changes in ABGs and MIP. The continuous infusion of epidural opiates should be the preferred analgesic method for patients at high risk of developing pulmonary complications following multiple rib fractures.
