Background and Aim of the work: The superficial erector
spinae muscle block or deep erector spinae muscle block is
an effective approach for analgesia in thoracic surgical and
chest trauma, providing excellent pain relief while reducing
narcotic requirements. Our study compares superficial
erector spinae muscle block versus deep erector spinae
muscle block for assessment of pain during radical
mastectomy procedures.
Patients and Methods: The patients were randomized into two
groups of 30 each. Group I received 20 mL of 0.25%
bupivacaine superficial to erector spinae muscle at the T4
level, while those in Group II received 20 mL of 0.25%
bupivacaine deep to erector spinae muscle at the T4 level.
Results: As regards VAS, there was a significant decline [P =
0.001] in the middle VAS in group II when distinguished
from group I at 12 h and a statistically significant decline [P
= 0.035] at 8 h postoperatively. Also, as regards the moment
of truth of first rescue analgesic, skilled was a considerably
longer in group II when compared with group I [p value=
0.005], and the total measurement of morphine devouring
was considerably lower in group II [6 ± 2 mg/24 h] when
distinguished from group I [9 ± 2 mg/24 h].
Conclusion: Superficial erector spinae muscle block may be
used as a method for controlling pain after radical
mastectomy, but deep erector spinae muscle block is more
effective than it.
