ABSTRACT
Objective To compare the analgesic efficacy and side effects of patient-controlled intravenous analgesia (PCIA) with Lornoxicam and patient-controlled epidural analgesia(PCEA) with morphine in patients undergoing Orthopaedics surgery. Methods 100 ASA Ⅰ-Ⅱ Patients scheduled for Orthopaedic surgery were divided randomly into two groups: Lornoxicam PCIA group( n =50) , Lornoxicam 48mg was diluted to 100ml with normal saline (0.9%NS). Morphine PCEA group( n =50), Morphine 9mg + bupivacaine 150mg were diluted to 100ml with normal saline (0.9%NS) .In both groups the patients were received PCA at a rate of 2ml/h with the bolus dose of 0.5ml and lockout interval of 15min. The loading dose was Lornoxicam 8mg plus Ondansetron 4mg in group PCIA and morphine 1mg and Ondansetron 4mg diluted to 10ml with normal saline (0.9%NS) in group PCEA 30 minutes before the end of operation. BP, RR, ECG, SpO_2 were monitored continuously after operation. Efficacy of analgesia was assessed by VAS scores. Side effects such as drowsiness, sweat, nausea, vomiting and skin pruritus were also observed. Results There was no significant difference in the mean VAS score between group PCIA and group PCEA at 4h, 8h, 16h ,20h, 24h, 32h and 48h. after operation. There was no significant difference in side effects between the two groups except the occurrence of sweat, nausea, vomiting and skin pruritus which was lower in group PCIA than in group PCEA ( P
