Brief Summary

The aim of this study is to evaluate analgesic effects Bupivacaine, Bupivacaine plus Dexmedetomidine and Bupivacaine plus Fentanyl in relieving pain after knee arthroscopic surgery.

Detailed Description

Forty-five patients ASA I - II aged 21-45 years for elective knee arthroscopy were divided into 3 groups: Group B, BD and BF. Group B received Intra-articular injection of 20 ml bupivacaine 0.25%+ 1 ml saline. Group BD received Intra-articular injection of 20 ml bupivacaine 0.25%+ 1 ml dexmedetomidine (100 ug).

Group BF received Intra-articular injection of 20 ml bupivacaine 0.25%+ 1 fentanyl (50 ug). The time of first request of analgesia and analgesic effect by VAS during the first 24 hr. postoperatively are recorded.

Primary Outcome Measures
NameTimeMethod
Duration of postoperative analgesiaFor 24 hours postoperative

start from intra-articular injection of the drug to the time of first request of analgesia

Secondary Outcome Measures
NameTimeMethod
total dose of rescue analgesia ( pethidine)within 24 hours postoperative

total consumption of rescue analgesia (pethidine) postoperative

pain intensity at rest (static)at 24 hours postoperative

measured by VAS on 0-10 cm scale(0- no pain and 10-the worst pain)

The number of participants with bradycardia, itching and hypotensionWithin 24 hours postoperative

The number of participants with bradycardia less than 50 beat per minute, itching and hypotension if mean arterial blood pressure less than 20% of basal )

patient satisfactionwithin 24 hours postoperative

Patient satisfaction by five point Likert-Like verbal rating scale by asking the patient how they evaluate the experience with the analgesic management after the the surgery? (5-very satisfied, 4-satisfied, 3-neutral, 2-dissatisfied, 1-very dissatisfied)

pain intensity on mobilization of operated knee (dynamic)at 24 hours postoperative

measured by VAS on 0-10 cm scale(0- no pain and 10-the worst pain)
