Results of acetic acid testing in frogs (n = 6 per group)

	MS222	MS222 + FM		Etomidate	Etomidate + FM		Benzocaine	Benzocaine + FM
1 h	1	2		0	0		0	4
3 h	2	2		1	0		1	4
6 h	4	2		0	1		0	4
24 h	2	2		1	4		1	5

Frogs were anesthetized with either MS222, etomidate (22.5 mg/L), or benzocaine (0.1%) and subsequently did or did not receive flunixin meglumine (FM; 25 mg/kg) in the right dorsal lymph sac. Data are reported as the number of animals that did not react when ≥10% acetic acid was applied to the back legs at the indicated time points.
