title: [Epidural buprenorphine does not improve diaphragmatic function after upper abdominal surgery].
abstract: We investigated the effect of epidural buprenorphine on diaphragmatic function using respiratory inductive plethysmography (RIP) in seven healthy patients after upper abdominal surgery. After surgery, changes of rib cage contribution to tidal volume (%RC) increased significantly from 25.3 +/- 7.3 (mean +/- SD) to 50.7 +/- 14.8% (P < 0.05). After the injection of epidural buprenorphine, visual analogue scale (VAS) score decreased significantly from 8.3 to 3.3 (P < 0.05). But, %RC was unchanged compared to the value before the injection. These results indicate that pain relief by epidural buprenorphine does not improve diaphragmatic function after upper abdominal surgery.
