To the Editor:--Sood et al. ascribe the first description of the esophageal detector to Wee. [1]This is not correct. Wee was an independent reinventor, the namegiver of the "esophageal detector device," and the first to publish a formal study on this issue. [2]But the first description of the syringe test was by Pollard 8 yr earlier.* Pollard and Wee agreed on these facts in the correspondence section of Anesthesia. [3,4].
