AbstractThe purpose of the present study was to investigate the efficacy of interpleural (IP) analgesia with bupivacaine or lidocaine after esophageal surgery and to measure the plasma concentrations of bupivacaine and lidocaine after intermittent IP administrations. Two IP catheters were inserted percutaneously in the seventh intercostal space during operation. Patients in the bupivacaine group (Gr B) received 1 mg/kg of 0.5% bupivacaine with epinephrine 1:200000 in 20 mL of saline 0.9%, patients in the lidocaine group (Gr L) received 3 mg/kg of 2% lidocaine with epinephrine in 20 mL of saline 0.9%, and patients in the placebo group (Gr P) received 20 mL of saline 0.9% every 4 h during 2 days. Pain was assessed by visual analog scale (VAS) every 4 h at rest (VASR), after a deep breath or cough (VASC), at the thoracotomy (VAST), and at the laparotomy (VASL). Morphine consumption using a patient-controlled analgesia (PCA) device was recorded. There was no significant difference in the mean VASR, VASC, and VASL scores among the three groups. VAST scores were significantly lower in Gr B at 12, 16, 28, and 32 h when compared with Gr P and Gr L (P < 0.05). There was no statistical difference in mean VAST between Gr L and Gr P. Total consumption of morphine was lower in Gr B than in Gr P and Gr L (41.2 +/- 13 mg vs 66.1 +/- 21 mg in Gr P (P < 0.02) and 75.5 +/- 27 mg in Gr L (P < 0.01)), but were similar in Gr L when compared with Gr P.(ABSTRACT TRUNCATED AT 250 WORDS)
