Comparing Dexamethasone With Dexmedetomidine as Additives to Bupivacaine in Adductor Canal Block for Knee Arthroscopy.

Summary

a comparison shall be conducted between dexamethasone accompanied by bupivacaine, on one hand, and dexmedetomedine accompanied by bupivacaine on the other hand and a control group for pain-free knee arthroscopic surgeries.

Conditions

• Pain, Postoperative

Interventions

PROCEDURE

Spinal anaesthesia

spinal anesthesia shall be conducted with 2.5 ml 0.5% hyperbaric bupivacaine at the L3/4 interspaces in the setting position.

PROCEDURE

ultrasound-guided Adductor Canal Block + dexamethasone

Ultrasound blocks will be done immediately after spinal anesthesia, before surgical intervention. A high-frequency linear ultrasound transducer was placed transverse to the longitudinal axis of the extremity at the midthigh level at a distance approximately halfway between the iliac spine and the patella. The femoral artery was identified underneath the sartorius muscle with the vein just underneath the artery. At this position, the saphenous nerve was placed lateral to the artery in the adductor canal (Fig. 1). A 10 cm Tuohy canula 18G "Gauge" (Braun Medical, Melsungen, Germany) was inserted, in plane, from the lateral side of the transducer, through the sartorius muscle with the tip placed lateral to the artery. then, a 20-ml mixture of 0.25% bupivacaine, and 4 mg dexamethasone will be injected.
