ObjectiveTo evaluate the efficacy and safety of patient-controlled intravenous analgesia (PCIA) of dezocine combined with sufentanil in burn patients after escharectomy or tangential excision followed by autologous skin grafting.MethodsSixty burn patients hospitalized in Department of Burns and Plastic Surgery of our hospital from February 2011 to December 2013, conforming to the study criteria and going to have escharectomy or tangential excision followed by autologous skin grafting, were divided into sufentanil group (S, n = 30) and dezocine+sufentanil group (DS, n = 30) according to the random number table. Patients in group S were given 150 mL normal saline containing 2.5 µg/kg sufentanil citrate and 6 mg tropisetron after skin grafting for 48 hours. Patients in group DS were given 150 mL normal saline containing 0.25 mg/kg dezocine, 1.5 µg/kg sufentanil citrate, and 6 mg tropisetron for 48 hours. Visual Analog Scale (VAS), Bruggrmann Comfort Scale (BCS), and Ramsay Sedation Scale were used to evaluate the sedative effect or analgesic effect, and their scores were recorded at administration hour (AH) 2, 6, 12, 24, and 48. The times of efficient injection and incidence of adverse effect within the 48 AH were recorded. Data were processed with analysis of variance for repeated measurement, t test, chi-square test, and Fisher's exact test.ResultsThere were no obvious differences in the scores of VAS and BCS between two groups at each time point (with t values from -0.426 to 0.864, P values above 0.05). The scores of Ramsay Sedation Scale in group S at AH 2, 6, 12, 24, and 48 were respectively (3.2 ± 0.6), (3.2 ± 0.5), (3.3 ± 0.7), (3.2 ± 0.4), and (3.3 ± 0.4) points, which were higher than those in group DS [(2.4 ± 0.6), (2.5 ± 0.5), (2.4 ± 0.6), (2.4 ± 0.4), and (2.4 ± 0.5) points, with t values from 5.302 to 8.391, P values below 0.001]. The times of efficient injection within the 48 AH was 6.8 ± 0.7 in group S and 6.5 ± 0.9 in group DS, showing no significantly statistical difference (t = 1.260, P > 0.05). Respiratory depression was not observed in both groups; the incidence of pruritus was the same, and that of urine retention was similar between the 2 groups within the 48 AH (with P values above 0.05). Within the 48 AH, the incidence of nausea and vomiting in group S was 26.7% (8/30), which was obviously higher than that in group DS (6.7%, 2/30, P < 0.05); the incidence of drowsiness in group S was 20.0% (6/30), which was significantly higher than that in group DS (no patient, P < 0.05).ConclusionsDezocine combined with sufentanil can provide effective postoperative analgesia with little adverse effect for PCIA in burn patients after escharectomy or tangential excision followed by autologous skin grafting, therefore it can be widely used.
