Forty-three patients undergoing median sternotomy were evaluated for postoperative pain and pulmonary function. Group 1 (n = 26) had harvest of the internal mammary artery (IMA) and group 2 (n = 17) did not. Postoperative pain and pulmonary function were evaluated on the fifth postoperative day. Both groups showed a decrease in forced expiratory volume in 1 second (group 1, 44%; group 2, 39%), but there was no significant difference in the loss between the two groups (p = 0.32). Using a numeric rating scale, there was significant increase in postoperative pain in group 1 (group 1, 6.35; group 2, 3.82; p = 0.0002). There is a suggestion that internal mammary artery harvesting itself worsens postoperative pulmonary function tests, and this may be related to a significant increase in postoperative pain.
对43例行正中开胸手术的患者进行了术后疼痛和肺功能评估。第1组（n = 26）采集了乳内动脉（IMA），第2组（n = 17）未采集。在术后第5天评估术后疼痛和肺功能。两组的第1秒用力呼气量均下降（第1组，44%；第2组，39%），但两组间的下降幅度无显著差异（p = 0.32）。使用数字评分量表，第1组术后疼痛显著增加（第1组，6.35；第2组，3.82；p = 0.0002）。有迹象表明，采集乳内动脉本身会使术后肺功能测试恶化，这可能与术后疼痛显著增加有关。
