1 Prospective, randomized comparison of extrapleural versus epidural analgesia for postthoracotomy pain  Andreas M. Kaiser, MD, Andreas Zollinger, MD, Diego De Lorenzi, MD, Felix Largiadèr, MD, Walter Weder, MD  The Annals of Thoracic Surgery  Volume 66, Issue 2, Pages (August 1998) DOI: /S (98)

2 Fig 1 Time courses of forced vital capacity (A) and forced expiratory volume in 1 second (FEV1) (B), expressed as percentages of the preoperative values. Data points represent the mean and the vertical error bars the ± standard error of the mean. The extended period of observation after discontinuation of thoracic epidural analgesia (TEA, see text) is indicated by a break in the x-axis. Overall recovery of the respiratory function was comparable in both groups, but on the second postoperative day, function tests were significantly better in the extrapleural intercostal analgesia (XPA) group. (∗p < 0.05 when time points of either group [n = 13] were compared by Student’s t test.) The Annals of Thoracic Surgery  , DOI: ( /S (98) )

3 Fig 2 Time course of postoperative visual analogue pain scores: 0 = no pain; 1 = little pain; 2 = moderate pain; 3 = severe pain; 4 = intolerable pain. Data points represent the mean and the vertical error bars the ± standard error of the mean. The extended period of observation after discontinuation of (TEA, thoracic epidural analgesia; see text) is indicated by a break in the x-axis. Except for the day of the operation and the first postoperative day, pain scores were lower in the extrapleural intercostal analgesia (XPA>) group (see text). ∗p < 0.05 when both groups [n = 13] were compared by Mann-Whitney rank sum test.

4 Fig 3 Time course of daily supplementary opiate (nicomorphine) consumption. Data points represent the mean and the vertical error bars ± the standard error of the mean. The extended period of observation after discontinuation of thoracic epidural analgesia (TEA, see text) is indicated by a break in the x-axis. Opiate consumption was lower in the extrapleural intercostal analgesia (XPA) group on postoperative day 2. (∗p < 0.05 when both respective time points of either group [n = 13] were compared by Student’s t test.) The Annals of Thoracic Surgery  , DOI: ( /S (98) )
