Objective To evaluate musical therapy combined with sufentanil postoperative intravenous analgesia on hemodynamic changes in patient accepted lung cancer operation.Methods Sixty lung cancer surgery patients (ASA Ⅰ-Ⅱ grade) were selected and divided randomly into musical therapy (group M; n =30) and control (group C; n =30).In group M,patients accepted music relaxation training for fifteen minutes before surgery,and music intervention for one hour at 3,7,15,19 hour after surgery.Whereas,in Group C,patients did not listen to any music during the same period.In the intensive care unit,patients were connected to a patient controlled analgesia (PCA) device.The PCA device (sufentanil 2 μg/kg,100 ml saline) was set to deliver a bolus of 2 ml,with a lockout interval of 10 min and background infusion volume of 0.5 ml/h.Hemodynamic changes,the visual analog scale (VAS) and consumption of sufentanil were recorded at the 4th,8th,12th,16th,20th and 24th hour after operation.Results SBP,DBP,HR and VAS of group M were significantly decreased compared to the group C,respectively (P ＜0.05),and significant difference was found in the PCA delivery frequency [group C (30.96 ± 4.00),group M (19.06 ± 3.49),t =12.39,P ＜ 0.01] and postoperative sufentanil consumption[group C (82.65±6.19)μg,group M (52.68 ±7.07)μg,t =20.00,P ＜0.01].Conclusions Musical therapy combined with sufentanil postoperative intravenous analgesia was able to produce better analgesic effect in the treatment of patient accepted lung cancer operation,which decreased postoperative sufentanil consumption and effectively reduced SBP,DBP and HR,and relieved the patient's anxiety.
