First, he talked about theoretical considerations, where he said that it is difficult to eliminate the bacteria from our skins. He added, chemical antiseptic will only decrease bacterial amounts, but can never eliminate it (16). Nonetheless, huge amount of skin bacteria is unseen under the surface in vessels, and glands, so that the chemical antiseptic cannot reach it. In 1950s, some experiments were made using medical student volunteers, and the result was that it required 7.5 million organisms for an actual infection to be done after inserting the needle. This situation uses assumptions kindly unfair concerning infection: a big amount of bacterial population on the skin, and all bacteria in the needle’s way would be transmitted into deeper skin covers. This also support that the required percentage of the numbers needed to create an infection is 0.05 percent. Second, Hoffman used observations in practice. He said that in 1960s a university medical officer made a survey with more than five-thousand injections in students, their relatives, and in addition to the university staff. The result was shocking, which proved that after six years no one had any infection. This proves that it was safe to be injected with no pre-injection as long as the injection site can be seen hygienic. …show more content…
He stated that in 1993 reporters conducted that giving pre-injection was not related to the increased number of infection risk in youth. The PHLS did not stop testing pre-injection skin preparation for grownup, and for people who have immune systems cooperated. Then, in 2001, Hoffman stated that was no enough research, and data about the skin disinfection. The writer used ethos to make the reader able to critically think about the issue from different perceptions, and to avoid being bias in his article so that it can be reliable. Furthermore, WHO-SIGN depicted its suggestions as being proof based. Nonetheless, they were just in light of master agreement and hypothetical reason and not upheld by all around composed test or, then again epidemiological investigations, nor by hypothetical justification and suggestive, spellbinding confirmation. In this way, such confirmation as was analyzed was really dismissed as deficient in quality to help their proposal. Different examiners every now and again ignore this critical capability to their
