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
