简要总结
This prospective parallel group randomized study will be conducted over 52 adult participants between 20 and 60 years ASA (American Association of Anesthesiologists) I and II undergoing lumbar spine surgery. The participants will be randomly allocated into 2 groups. Group BM (Bupivacaine + magnesium sulfate) will receive bilateral erector spinae block using bupivacaine and magnesium sulfate after induction of general anesthesia, while group BD (Bupivacaine + dexmedetomidine) will receive bilateral erector spinae block using bupivacaine and dexmedetomidine after induction of general anesthesia. Hemodynamic changes will be monitored intraoperatively, and postoperative pain will be assessed using the visual analogue scale in order to assess the need for postoperative analgesia.
详细描述
This prospective parallel group randomized study will be conducted over 52 adult participants between 20 and 60 years ASA (American Association of Anesthesiologists) I and II undergoing lumbar spine surgery. The participants will be randomly allocated into 2 groups.
General anesthesia will be induced using propofol 1-2mg/kg, fentanyl 2ug/kg, and atracurium 0.5mg/kg.
Both groups will receive bilateral erector spinae block Group BM will receive bilateral erector spinae block .A technique that will be performed ultrasound guided to identify the transverse process of T10, and an 18G (gauge) needle will be introduced in plane deep to the erector spinae muscle after which a combination of 20ml bupivacaine 0.25% and 2.5 ml magnesium sulfate.
While group BD will receive the same block with the with 20ml bupivacaine 0.25% and dexmedetomidine 1ug/kg.
Hemodynamic changes will be monitored intraoperatively, for detection of any variations.

结局指标
主要结局
Dose of postoperative nalbuphine
时间窗: 12 hours
Total dose of postoperative nalbuphine will be measured depending on the visual analogue scale
Measurement of the duration of postoperative analgesia
时间窗: 12 hours
Postoperative analgesia duration will be assessed using the visual analogue scale which is from 0-10 were 0 means no pain and 10 is the worst pain
次要结局
- Patient satisfaction(48 hours)
