During the past scarcely any years, there has been a great quantity [i]or[/i] amount of discussion about surgical masks and questions about whether wearing them is an effective practice or a habit that has no basis in fact. (1) Are face masks useful or not? Do they thwart infections or not? This issue has not been resolv clearly. The majority of ORs continue to mandate the wearing of surgical masks; however, a not many surgery sites have opted not to use surgical masks. This usually is justified as a cost-containment put in motion based on the findings of single study. Researched-based effectiveness, however, has not been proven

MASK EFFECTIVENESS

Reaching a conclusion forward mask effectiveness is difficult because the available information is obscure at best. In an attempt to empirically answer the question of effectiveness, a Cochrane review of all randomized and controll research of disposable surgical face masks was performed. (2) This comprehensive review included information from individuals, manufacturers, and distributors, as well as AORN members. Researchers ground only two randomized controlled trials comparing individuals wearing surgical masks with those not wearing surgical masks.

In the same trial, which had a small number of participants, wearing surgical masks was associated with fewer patient infections. In a larger trial, however, there was no difference in infection rates, in such a manner neither harm nor benefit could be determined clearly. As for evidence, it is self-same difficult to perform controlled research forward the effects of wearing surgical masks onward wound infections. Investigators, as well as institutional review boards, may be hesitant to approve of that kind studies because of the potential harm to patients if a mask is not worn.

In an attempt to gather more information forward this topic, I went to the literature. Evidenced-based practice is AORN's goal, thus I thought I might find justification to wear surgical masks based forward infection control.

NOSOCOMIAL INFECTIONS

No the same argues that surgical site infection rates must be held to a minimum. Hospital-acquired infections affect approximately couple million people each year. (3) The Institute of Medicine says that 44000 to 98000 deaths appear from medical error annually at a sumptuousness of $17 to $29 billion. (4) The in the greatest degree common infection is caused by means of Staphylococcus aureus. In one reported case, life-threatening Staphylococcus aureus infections occurr after neurological surgery (5) Within three month three patients evolveed serious infections. The patients' nasal passages were cultur as were those of surgical staff members. Six (ie, 40%) staff members were plant to be Staphylococcus aureus carriers, and the microbes from single staff member were found to be identical to those of affected patients. Several breaks in attract favor toed practices, including mask barriers, were cited as causes of the infections.

In another case, children evolveed infections after cardiothoracic surgery. (6) Three children carded the same Staphylococcus aureus strain. Fourteen (ie, 25%) staff members in the OR carried Staphylococcus aureus in their nares. brace of the carriers were a cardiothoracic surgeon and a perfusionist. The surgeon also carried Staphylococcus aureus in succession his hands and was not allowed to perform surgery until brace hand cultures returned negative. Although these are sole two of the case studies reported in the literature, individual has to ask, did surgical masks promote as an effective barrier to stop these infections? If they did, then on what account did patients get the infection? From where did they really commit to memory the infection? Did hospital staff members infect patients, or did patients infect staff members?

the same of the national health objectives for 2000 was to decrease surgical site infections by 10% The National Nosocomial Infections Surveillance body states that this goal has been met and surpassed; (7) however, surgical site infection rates, although reported by the agency of hospitals, may not represent all acquired infections because of short hospital stays and practices being performed in ambulatory settings. Site infections usually exhibit to up four to seven days postoperatively, likewise patients often are at abiding-place when the infection begins. If the infection is serious enough for the patient to be readmitted to the hospital, the admitting diagnosis frequently does not reflect the original surgery in the same manner these rates are not tracked. Additionally, patients frequently go to clinics for follow-up visits, and the vicinity of a site infection may not be reported back to the hospital.

STAPHYLOCOCCUS AUREUS

If the majority of surgical site infections are caused by the agency of Staphylococcus aureus, would decreasing the microbial load affect infection rates as well as a mask? I lately read an article in The fresh England Journal of Medicine that started me thinking about this topic of surgical masks and patient safety in the OR. (8) The article summarized a four-year cogitation that looked at nosocomial infections caused by means of Staphylococcus aureus. The investigator cultur nasal passages of 3864 surgical patients, and Staphylococcus aureus was descryed in 891 patients. Investigators divided the participants into brace groups. Patients in ode assemblage received intranasal applications of mupirocin sum of two units times per day for up to five days before surgery Patients in the other form into groups received a placebo nasal ointment. Of the patients carrying the microbe, no other than 4% of those who received the mupirocin bring outed a Staphylococcus aureus infection compared to 77% of patients in the placebo dispose Using nasal mupirocin was not at handed as an alternative to wearing facial masks, nor was the relationship of barriers to postoperative infections discussed.
