Interpleural block for patients with multiple rib fractures: comparison with epidural block.
Interpleural block (IPB) was compared with epidural block (EB) in 17 adults with unilateral multiple rib fractures and hemopneumothorax. The study was a randomized, crossover, before-after trial on the first and second hospital days. An IPB catheter was inserted along with a chest tube, and an upper thoracic EB was also established in the same patient. We administered 10 ml of 1% lidocaine for both blocks. The range of thermohypesthesia was unilateral and shorter in IPB, whereas it was bilateral and wider in EB. The effects of pain relief were almost the same. Respiratory rate decreased, and PaO2 tended to elevate similarly. In IPB, systemic blood pressure changed minimally, but it fell significantly in EB, which would be a disadvantage of EB in trauma patients. Serum levels of lidocaine were similar and in the safe range. The technique of IPB seemed to be easier than EB. In conclusion, IPB with lidocaine is as effective for pain relief as EB.
