It is a great pleasure to accept any comment and reply to it.

With regard to the dose of hyperbaric bupivacaine not being fixed for the groups, we tried three groups at the start of the study, and the third group was given 10 mg of bupivacaine and 1 ml of normal saline; however, it resulted in failure to reach the desired level and motor block, and thus it was unethical to use this group as most of the patients were reverted to general anesthesia.

In addition, I accept that low volumes of bupivacaine can cause low levels of motor block, but when we added ketamine it gave us the same level of motor block with earlier onset of action.

With regard to the point that ketamine shortens the time of spinal anesthesia, we did not compare the same dose of bupavicane in the two groups with, without ketamine for the previous reason; however, in our study, we compared the normal volume of bupivacaine in spinal anesthesia, low dose in addition to ketamine for faster recovery.

With regard to the level of surgery, most of the surgeries were urological with high level of block up to T7.

About the last concern, you are right – it is spinal injection and not epidural injection, and we apologize for this mistake.
