Background: Lower abdominal surgeries often result in
severe pain, which in turn can affect the pattern of breathing
and cause discomfort, irritation, and poor patient compliance.
This investigation aimed to compare the analgesic efficacy of
adding dexmedetomidine (DEX) as an adjuvant to
bupivacaine in TAP block intraoperatively and
postoperatively in lower abdominal surgeries. Methods: This
prospective investigation included 60 cases undergoing lower
abdominal surgery, randomly assigned into two equal groups.
Group B received 40 mL of 0.25% bupivacaine (20 mL per
side), while Group BD received 20 mL of 0.5% bupivacaine
mixed with 0.5 mcg/kg DEX and diluted to 40 mL (20 mL per
side) for TAP block. Results: NRS measurements at 2h, 4h,
and 6h were statistically significantly diminished in Group BD
in contrast with Group B (P
