Suragul W, Tantawanit A, Rungsakulkji N, Muangkaew P, Tangtawee P, Mingphrudhi S et al.

BJS Open 2022; 6: zrac066.

The analysis included 150 patients in three groups. Pain scores were similar 2h after surgery. Opiate use in the first 24h was lower in patients who had a rectus sheath block compared to subcutaneous, or no infiltration (P=.043).

Comment: Small study but intramuscular infiltration seems important.
