ABSTRACT

ObjectiveTo evaluate the efficacy of preemptive analgesia with parecoxib for acute postoperative pain after pulmenary lobectomy.MethodsSixty ASA Ⅱ or Ⅲ patients of both sexes aged 20-64 yr weighing 50-80 kg undergoing elective pulmonary lobectomy were randomly divided into 3 groups ( n =20 each) control group (group C); group A (parecoxib 40 mg was injected iv at 20 min before surgery) and group B (parecoxib 40 mg was injected iv when skin was sutured).Patient controlled intravenous analgesia (PCIA) with sufentanil and ramosetron (continuous background dose 2 ml/h,bolus dose 0.5 ml,lockout time 15 min) was used after surgery.When VAS score ＞ 3,iv bolus of tramadol 1-2 mg/kg was injected as rescue medicine.Agitation condition was observed after operation.The number of successfully delivered doses and the number of attempt were recorded.The consumption sufentanil and the number of rescue medicine were recorded during 24 h after surgery.ResultsThe incidence of postoperation agitation,number of successfully delivered doses and number of attempt,consumption sufentanil and number of rescue medicine were significantly lower in groups A and B than in group C.The consumption sufentanil and number of rescue medicine were significantly lower in group A than in group B ( P ＜0.05).ConclusionParecoxib can use for preemptive analgesia in patients after thoracic surgery,reduce the complication during anesthesia recovery and the opioid analgesics consupmtion.
