编辑同志: 我們学習了楊琦同志發表的試制氯霉素注射剂的方法,曾配制了200支安瓿,供小兒科临床試用,發現有三个病例經注射后臀部有紅腫結塊現象。为了研究此現象是否由刺激引起,我自己注射了一次,开始並無疼痛紅腫現象(可能由于普魯卡因的局部麻醉作用),經半小时后,注射处局部有点隐痛,临床医师研 Editor’s Comrade: We studied the trial of chloramphenicol injection by Comrade Yang Qi. We have prepared 200 ampoules for clinical trial in pediatrics and found that there are three cases of inflamed clumps on the buttocks after injection. In order to investigate whether this phenomenon is caused by irritation, I injected it myself once and started to have no pain and swelling (possibly due to the local anesthetic effect of procaine). After a half hour, the injection site was a little painful.
