Materials and methods: The present study was conducted on 52 adult patients aged between 20- 60 years with American Society of Anesthesiologists physical status grade I or II scheduled for diagnostic or therapeutic knee arthroscopic surgery under subarachnoid block. Patients were divided into 2 groups. Group I received 20 ml of 0.25% bupivacaine intra‑articularly with 1mg of morphine and group II received 3 mg of morphine. Post‑operative pain was assessed with 10‑point VAS, which was recorded after 1, 2, 6, 12 and 24 h after surgery.

Results: Out of 52 patients, males were 32 and females were 20. VAS at 1 hour in group I was 4.5 and in group II was 3.2, at 2 hours was 4 in group I and 2. In group II, at 6 hours was 3.5 in group I and 1 in group II, at 12 was 2.5 in group I and 0 in group II, at 24 hours was 1.2 in group I and 0 in group II. The difference was significant (P< 0.05). Side effects in group I was pruritis seen in 2 and 1 in group II, nausea in 3 and 2 in group I and II respectively, urinary retention in 2 and 1 in group I and II respectively. The difference was significantly (P< 0.05).

Conclusion: Authors found that morphine in effective in arthroscopic knee surgeries. With 3mg morphine VASs core found to be less.
