Does the addition of morphine to intra-articular bupivacaine injection improve pain relief after knee arthroscopy?
A randomised double-blind prospective trial in patients undergoing knee arthroscopy was performed to determine whether the addition of morphine to bupivacaine for intra-articular injection gave any additional analgesic effect over the use of bupivacaine alone. In group A ( n=22) 3 ml water and 10 ml...

Summary: | A randomised double-blind prospective trial in patients undergoing knee arthroscopy was performed to determine whether the addition of morphine to bupivacaine for intra-articular injection gave any additional analgesic effect over the use of bupivacaine alone. In group A (
n=22) 3 ml water and 10 ml 0.5% bupivacaine were injected intra-articularly. In group B (
n=22) 3 mg morphine in 3 ml water and 10 ml 0.5% bupivacaine were used. Pain was evaluated at intervals using a visual analogue scale and by amount of oral analgesia required. The results showed that the addition of morphine to intra-articular bupivacaine offered no significant analgesic benefit. |
