Study of 34 patients who had undergone thoracotomy revealed that the group given intercostal nerve block analgesia had a significantly smaller decline in vital capacity after operation than did the group given narcotic analgesia only. The postoperative increase in arterial CO2 tension of the nerve block group also was significantly smaller than that of the narcotic group. The study suggests that intercostal nerve block for post-thoracotomy analgesia offers some advantage in preserving effort-dependent pulmonary function when compared with postoperative narcotic analgesia.
对34例接受开胸手术的患者进行的研究显示，与仅给予麻醉性镇痛的组相比，接受肋间神经阻滞镇痛的组术后肺活量下降明显更小。神经阻滞组术后动脉血二氧化碳分压的升高也明显小于麻醉组。该研究表明，与术后麻醉性镇痛相比，肋间神经阻滞用于开胸术后镇痛在保留依赖用力的肺功能方面具有一些优势。
