Duration of surgical anesthesia (that is, righting and withdrawal reflexes remained absent), when an abdominal incision was created to perform a mock oocyte harvest. The upper line represents the upper 95% confidence limit for MS222 (34 min), whereas the lower line represents the 10-min minimum needed to perform a surgical oocyte harvest. Doses of fluixin meglumine (flunixin) are given in mg/kg; doses of etomidate (Et) are given in mg/L; doses of benzocaine (B) are given in percentage concentration; and the dose for MS222 was 2 g/L.
