Study type
Interventional
Description of intervention(s) / exposure
group H: received 15ml bupivacaine 0.5%.
the solution is stored for more than 24 hours in a freezer cabinet in which the temperature was maintained at 20 degrees C; The syringes and needles used for anesthesia were stored in the same room.

Treatment: Drugs
Comparator / control treatment
group C: the solution used (15 ml of 0.5% bupivacaine) was warmed up to 37 degrees C using a water bath. Bupivacaine ampoules were maintained at a temperature of 37 dgrees C when stored in the water bath for 20 minutes. The syringes and needles used were stored in this water bath for more than two hours, before the start of the procedure.

Outcomes
Primary outcome [1] 287833 0
onset time of the sensory blockade: time interval between end of local anesthetic injection and complete sensory blockade in nerve-specific dermatome
Timepoint [1] 287833 0
every five minutes and for 30 minutes. The innervated areas (each dermatome) was evaluated using a pinprick and was rated on a scale from 100% (normal sensation) to 0% (no sensation)
Primary outcome [2] 287834 0
onset time of the motor blockade was defined as score 0 of Bromage modified scale
Timepoint [2] 287834 0
every five minutes and for 30 minutes
Secondary outcome [1] 298900 0
the duration of analgesia: assessedby the first analgesia request
Timepoint [1] 298900 0
regular intervals 1, 3, 6, 12, and 24 h

Summary
Brief summary
In regional nerve blocks, the use of adjuncts along with local
anesthetics can improve the anesthetic effect.but, can we do without adjuncts? warming anesthetic solution can be proposed as an alternative .
