To the Editor: Dr. Burman's report of his technique for introduction of the Crosby-Kugler capsule in infants is very welcome. While polyvinyl tubing is more satisfactory than polyethylene tubing from many standpoints, use of it is probably not the sole reason for Dr. Burman's successes. One other reason might be that Dr. Burman's infants, as mentioned, were of low weight for age, probably debilitated from disease, possibly premature. Such infants are unable to struggle effectively. Perhaps he dealt with sicker infants.
The technique I reported was developed after I had failed to pass the capsule upon attempting to introduce it by mouth, even with the infant sedated. It works. But that technique which obtains the desired result and is the simplest is surely the one to choose. I suggest that Dr. Burman's technique be tried first. If one is unsuccessful, there is another method to fall back on. As for
