Masks are bad:

Surgical masks as source of bacterial contamination during operative procedures

Results

The bacterial count on the surface of SMs increased with extended operating times; significant difference was found between the 4- to 6-hour and 0-hour groups (p < 0.05). When we analysed the bacterial counts from the same surgeon, a significant increase was noted in the 2-hours group. Moreover, the bacterial counts were significantly higher among the surgeons than the OR. Additionally, the bacterial count of the external surface of the second mask was significantly higher than that of the first one.

Conclusions

The source of bacterial contamination in SMs was the body surface of the surgeons rather than the OR environment. Moreover, we recommend that surgeons should change the mask after each operation, especially those beyond 2 hours. Double-layered SMs or those with excellent filtration function may also be a better alternative.

[they] are lying to us - masks suck ass:

Does Evidence Based Medicine Support the Effectiveness of Surgical Facemasks in Preventing Postoperative Wound Infections in Elective Surgery?

Results: No significance difference in the incidence of postoperative wound infection was observed between masks group and groups operated with no masks (1.34, 95% CI, 0.58-3.07). There was no increase in infection rate in 1980 when masks were discarded. In fact there was significant decrease in infection rate (p < 0.05).

Conclusion: From the limited randomized trials it is still not clear that whether wearing surgical face masks harms or benefit the patients undergoing elective surgery.

Anons,

We've been through a lot.

But we all raised good, patriotic American Kids, so I have hope for the future.

God bless each and everyone of you.
