Abstract:
ObjectiveTo assess the effects of intra-articular Hydromorphone with Ropivacaine for postoperative analgesia after arthroscopic knee surgery.Methods 90 patients undergoing arthroscopic knee surgery were randomly divided into 3 groups. Group R: 0.375% Ropivacaine 20ml; group H1: Hydromorphone 0.3 mg and 0.375 % Ropivacaine 20 ml; group H2: Hydromorphone 0.6 mg and 0.375 % Ropivacaine 20 ml. The visual analogue scale (VAS) at rest were recorded at 6, 12, 18 and 24 h after surgery, Duration of analgesia, number of patients and frequency requiring Parecoxib at 24 h after surgery were observed.Results Compared with group R, VAS of group H1 and group H2 were signiifcantly lower at 12 and 18h after the operation, duration of analgesia was much longer, number of patients and frequency requiring Parecoxib was lower in group H1 and H2 (P < 0.05); Compared with group H1, No signiifcant differences of VAS, duration of analgesia and number of patients and frequency requiring Parecoxib of group H2.Conclusions After knee arthroscopic surgery, intra-articular 0.3 mg Hydromorphone can signiifcantly improve the efifcacy of Ropivacaine for postoperative analgesia; the efifcacy of Hydromorphone can’t increased with the increase of dosage.
