Abstract
Aim of the work
To compare the use of forearm tourniquet versus usual upper arm tourniquet and to evaluate the effect of addition of magnesium sulphate to local anesthetic for IVRA, in an attempt to reduce tourniquet pain and discomfort and to improve the postoperative analgesia.
Conclusion
The use of forearm tourniquet is superior to the use of upper arm tourniquet for IVRA, because it produces operative analgesia of better quality than upper arm IVRA with 50% less (lidocaine or lidocaine MG). And the addition of magnesium to lidocaine in IVRA demonstrated decreased pain associated with tourniquet. It also shortend sensory and motor block onset times. Prolonged sensory and motor block recovery times, and improved the quality of anesthesia while prolonging the time for first postoperative analgesic requirement.
