Laparoscopic cholecystectomy (LC) has been routinely performed under general anesthesia
despite the several disadvantages of general anesthesia compared to regional anesthesia.

There are multiple reports that have been published regarding the feasibility of spinal
anesthesia for LC associated with many problems such as referred shoulder pain secondary to
intra-abdominal pneumoperitoneum; patient anxiety, pain, and discomfort; and inadequate
sedation.The aim of our study is to prospectively observe the feasibility of using
intravenous dexmedetomidine to abolish patient discomfort and shoulder pain, thus making the
patient more comfortable without causing excessive sedation and respiratory depression.
