The vast majority of glass cuts will not be infected with tetanus. The prerequisite for tetanus to occur is to have a closed environment, contaminated with tetanus bacteria, tetanus bacillus as an anaerobic bacteria, the prerequisite must have a closed environment to survive. After the glass cut hand through timely debridement and be sutured, in the wound does not leave a dead cavity, does not leave a closed sterile environment, even if there is tetanus bacillus can not survive and reproduce. Therefore, the majority of glass cuts will not be infected with tetanus after prompt debridement and suturing. If there is a suspected dead space, a closed anaerobic environment may be formed, and tetanus infection can be prevented by injection of tetanus antitoxin.
