Abstract :
Multimodal anaesthesia is recommended for treatment of postoperative pain. The rationale behind this is to
attain sufficient analgesia due to the synergistic and additive between various analgesics with concomitant
reduction in dose of any individual drug required to attain the same effect. Therefore a combination
of Ropivacaine with Morphine intra-articular was hypothesized to have better and longer postoperative
analgesic effects as compared to Ropivacaine alone.
Knee arthroscopies are being performed more and more often as day care surgeries under regional
anaesthesia hence there is a need for suitable postoperative analgesia regimen with a long duration of
action, good safety profile and which provides the ability for the patient to ambulate.
This study was undertaken to compare the effects of intra-articular Ropivacaine with the effects of a
combination of intra-articular Ropivacaine and Morphine. 60 patients were divided into two groups of
30 each, one receiving Ropivacaine and the other the combination of Ropivacaine and Morphine.
In this study we found that post-operative pain was less in the group receiving the combination of intraarticular
Ropivacaine and Morphine. The need for rescue analgesics was also found to be less in the group
receiving the combination of intra-articular Ropivacaine and Morphine.
