ABSTRACT

OBJECTIVE:

To investigate the effect of intranasal (IN) flunixin meglumine (FM) and intra-inguinal (IG) lidocaine on castration inflammation using prostaglandin E2 (PGE2) concentration as a biomarker.

METHODS:

This randomized controlled trial was conducted in March 2022. Blood was collected at -24, 1, and 24 hours postcastration for PGE2 quantification from 195 piglets that received 1 of 8 treatments (1) saline (1.5 mL) applied IG and IN (0.2 mL) followed by surgical castration (n = 24); (2) saline (1.5 mL) IG and IN (0.2 mL) followed by sham castration (25); (3) lidocaine (20 mg/kg or 1.5 mL) IG followed by surgical castration (24); (4) lidocaine (20 mg/kg or 1.5 mL) IG followed by sham castration (25); (5) FM (2.2 mg/kg) IN followed by surgical castration (25); (6) FM (2.2 mg/kg) IN followed by sham castration (24); (7) lidocaine (20 mg/kg or 1.5 mL) IG and FM (2.2 mg/kg) IN followed by surgical castration (24); and (8) lidocaine (20 mg/kg or 1.5 mL) IG and FM (2.2 mg/kg) IN followed by sham castration (24).

RESULTS:

Prostaglandin E2 concentrations did not increase following the castration procedure and were not an effective biomarker of castration inflammation. Piglets that received lidocaine demonstrated no difference in PGE2 levels across all time points. Piglets administered FM had lower PGE2 concentrations at 1 hour and 20 minutes postdrug administration in both the sham and castrated piglets.

CONCLUSIONS:

Prostaglandin E2 was not an effective biomarker to quantify castration inflammation. Flunixin meglumine was able to reduce PGE2 concentration in piglets regardless of castration procedure, but lidocaine had no impact. Decreased PGE2 levels in FM-treated pigs are likely associated with the drug's ability to mitigate a noncastration-associated inflammatory process occurring independent of the castration procedure. CLINICAL RELEVANCE Flunixin meglumine reduced circulating PGE2 concentration in the blood, regardless of the castration procedure, indicating a potential for the drug to mitigate an inflammatory process unrelated to castration.
