Active Comparator: 2.5 ug hydromorphone recieved group
the 2.5 μg hydromorphone group (2.5HG) received 1.2 (6 mg) mL of 0.5% hyperbaric bupivacaine and 2.5 μg of hydromorphone in 0.05 mL of saline
Drug: Hydromorphone
2.5, 5, 10 ug of hydromorphone, intrathecal injection, single injection. duration of intrathecal injection are not fully studied.
Active Comparator: 5 μg hydromorphone group
5 μg hydromorphone group received 1.2 mL of 0.5% hyperbaric bupivacaine and 5 μg of hydromorphone in 0.05 mL of saline
Drug: Hydromorphone
2.5, 5, 10 ug of hydromorphone, intrathecal injection, single injection. duration of intrathecal injection are not fully studied.
Active Comparator: the 10 μg hydromorpnone group
the 10 μg hydromorphone group received 1.2 mL of 0.5% hyperbaric bupivacaine and 10 μg of hydromorphone in 0.05 mL of saline.

Detailed Description:

Sixty patients who were undergoing unilateral knee arthroscopy randomly received unilateral spinal anesthesia with 0.5% hyperbaric bupivacaine 6 mg combined with normal saline 0.05 mL or hydromorphone 2.5, 5 or, 10 μg/0.05 mL. The verbal numerical rating scale (VNRS) pain scores were measured at 30 minutes and 2, 4, 6, 12 and 24 hours postoperatively, and the side effects of hydromorphone were recorded.
