Text Correction
There were several errors in the original article [1]:
  • In the sixth line of the abstract, instead of “The anesthesia was induced by an intramuscular injection of dexmedetomidine, tiletamine zolazepam, and butorphanol in 12 pigs”. It should be “The anesthesia was induced by an intramuscular injection of dexmedetomidine, tiletamine-zolazepam, and butorphanol in 12 pigs”.
  • In Section 3.3, on page 6, instead of “In all pigs, the average Cmax for all drugs was 12 (range 10–13) after administration of the IM induction drug combination”, it should be “In all pigs, the average Cmax for all drugs was reached 12 (range 10–13) min after administration of the IM induction drug combination”.
  • In Section 3.3, on the bottom line of page 6, instead of “IV (Table 2)”, it should be “IV (Figure 2)”.
Figure/Table Legend
In the original article, there were mistakes in the legend for Table 3 and Figure 2. The correct legends appears below.
Table 3. Drug analysis data.
Figure 2. Profiles of log plasma concentrations for each drug over time for short-term anesthesia induced by intramuscular administration of dexmedetomidine 0.025 mg/kg, tiletamine 2.5 mg/kg, zolazepam 2.5 mg/kg, and butorphanol 0.1 mg/kg in pigs (n = 7). Group S (dotted lines n = 3) received a single dose at time zero. Group R (solid lines n = 4) also received one-third of the initial dose intravenously at 60 min. Time to first spontaneous movement is indicated with a dotted arrow for Group S and a solid arrow for Group R.
Error in Table
In the original article, there was a mistake in Tables 2 and 4 as published.
  • On page 8, in the third line of the footer of Table 4, instead of “and group Ralso”, it should be “and group R also”.
  • The footnote under Table 4 should be placed under Table 2.
The corrected Table 2 and Table 4 appear below. The authors apologize for any inconvenience caused and state that the scientific conclusions are unaffected. The original article has been updated.
We apologize for any inconvenience caused to the readers by this change. The change does not affect the scientific results. The original article has been updated.

All pigs received a single dose at time zero, and group R also received one-third of the initial dose intravenously at 60 min. All blood samples were taken in relation to the noted observation except for lateral recumbency, which was taken at 5 min after induction. Plasma concentrations were available for seven pigs.
