Abstract:
Objective To compare the efficacy of patient-controlled intravenous analgesia (PCIA),patient-controlled paravertebral block (PCPB) and patient-controlled epidural analgesia (PCEA) in patients after lobectomy performed via video-assisted thoracoscope (VAT).Methods Forty-eight ASA Ⅰ or Ⅱ patients,aged 50-64 yr,with a body mass index of 20-25 kg/m2,undergoing elective lobectomy via VAT,were randomly divided into 3 groups ( n =16 each):PCIA group,PCPB group and PCEA group.PCIA solution contained sufentanil 2 μg/kg in 100 ml of normal saline,The PCA pump was set up with a 2 ml bolus dose,a 15 min lockout interval and background infusion at a rate of 2 ml/h.PCPB solution contained 0.75％ ropivacaine 60 ml in 250 ml of normal saline and the pump was set up with a 5 ml bolus dose,a 15 min lockout interval and background infusion at a rate of 5 ml/h.The PCEA solution contained 0.75％ ropivacaine 50 ml and sufentanil 1 μg/kg in 250 ml of normal saline.The PCEA pump was set up to deliver a 5 ml bolus dose with a 15-min lockout interval and background infusion at 5 ml/h.VAS score was maintained ≤3.Peripberal venous blood samples were obtained before operation ( baseline),and at 24 and 48 h after operation for determination of the plasma cortisol concentration.The side effects were recorded.Results The plasma cortisol concentration and incidence of Somnolence were significantly lower in groups PCPB and PCEA than in group PCIA ( P ＜ 0.05 ).The plasma cortisol concentration was significantly lower in group PCEA than in group PCPB ( P ＜ 0.05).Compared with the baseline value,the plasma cortisol concentrstion was significantly higher after operation in groups PCIA and PCPB ( P ＜ 0.05),while no significant change was found in group PCEA ( P ＞ 0.05).Conclusion Compared with PCIA,PCEA can inhibit the stress response,while PCPB can reduce the stress response with good safety in patients after lobectomy performed via VAT if they can provide the equivalent postoperative analgesia.
