Abstract
PURPOSE:
The aim of this prospective randomised study was to compare the effect of cold bupivacaine 0.5% and magnesium added to normal tempretutre bupivacaine 0.5% during sonar guided combined femoral- sciatic nerve block for arthroscopic knee surgery on onset of sensory and motor block , intraoperative anesthesia , duration of sensory and motor block, postoperative …show more content…
Onset of both sensory and motor block was significantly shorter in both group II and III. Intraoperative anesthetic quality was comparable between groups with good patient and surgeon satisfaction. The time to first analgesia was significantly longer in group II and III.and the total opioid consumption were significantly lower in Group II and III and duration of analgesia and motor block were significantly longer in group II and III t (p = 0.015, p = 0.019, respectively). There was no difference in the incidence of side effects.
CONCLUSIONS:
The use of cold 0.5% bpivacaine or The addition of magnesium to normal tempreture 0.5%bupivacaine prolongs the sensory and motor block duration without increasing side effects and enhances the quality of intra and postoperative analgesia with better patient satisfaction in patients receiving sonar guided femoral and sciatic nerve block for arthroscopic ACL reconstruction surgery..
Introduction
The most common used drug in nerve block is bupivacaine 0.5% as a local anesthetic. Enhancement of the local anesthestic effect is produced by a decrease in temprature to 4 °C. (1) Temprature may thus be an interesting physical variable in the study of nerve blocking mechanisms.
