The difference in analgesic activity following lumbar (group I) or thoracic (group II) epidural administration of 50 ug sufentanil was studied after cholecystectomy. Fifteen patients in each group were evaluated for pain relief using a linear analog scale (LAS), heart rate (HR), mean arterial pressure (MAP), respiratory rate (RR), peak expiratory flow (PEF), forced vital capacity (FVC), forced expiratory volume (FEV,) and arterial CO 2 tension (Paco 2 ). In five additional patients in each group 75 μg sufentanil was injected for determination of serum levels. Pain scores were lower than three in both groups after 10 min, while mean pain scores remained below one from 20 min until 2 h following injection in both groups. Satisfactory pain relief lasted for 4 h. RR was significantly decreased from two until 360 min. in the lumbar group and from five until 120 min in the thoracic group. Paco 2 was raised in both groups only during the first hour. PEF and FVC were significantly improved compared to control 1, 2 and 4 h following injection. Serum sufentanil levels reached a maximum of 0.299 ±0.052 ng.ml ‐1 in the lumbar group and 0.377 ± 0.076 ng–ml ‐1 in the thoracic group after 5 min. There were no significant differences between the two groups in the variables studied.
