Why do doctors wear face masks while preforming surgery?
To not breath germs onto the person having surgery. They wear gowns and gloves and hair nets for the same reason. The surgery is done in a sterile environment.It has the added benefit of protecting them from bodily fluids (HIV, HEP C) that can carry disease.
Food workers wearing surgical masks?
I think it should be required. I feel somewhat scared to eat food from places where workers don't wear gloves, not knowing how clean their hands are. I also think that in addition to gloves, hairnets, sanitary clothing, etc. that you see cooks wear, I think it would only be completely sensible for workers in the food industry to wear surgical masks as well. If I walked into a fast food place or deli in a grocery store and saw the workers masked and gloved, I would feel much safer eating from there. Anyone else feel this way?
Why do surgeons wear scrub caps?
It (supposedly) keeps hairs from falling into the sterile surgical field.But, as you can see in the photo below, there is usually some hair sticking out somewhere.[1]So the Surgical Nurses Association (AORN) advocated banning the traditional, cool looking surgeons cap (Grey’s Anatomy cool and all that) in favor of the Bouffant style cap or the “Hood”, citing risk of infection. Surgeons however, thought these looked dorky (see below) and basically refused.The American College of Surgeons (ACS) defended the traditional cap, noting, among other points, that it is a “symbol of the surgical profession and a matter of legitimate personal preference”. Plus, It makes surgeons look cool (see below).OK, wrong picture, but you get the idea. There. Cool, right?Guess who won? Yep, the surgeons got to keep their cool hats. It helped that there were no studies or evidence that changing hats made any difference in the infection rates.When I was a first year resident, I was told I had to wear the “hood” because I had a beard.So I still do. It’s probably unnecessary, but since no one else wears them, at least I look distinctive. Or something.Footnotes[1] The surgical cap: Symbol, science, argument, and evidence | The Bulletin
My ten year old daugther is having surgery?
That was maybe a bit insensitive of the doctor to tell a 10 year old girl, and probably unnecessary. You don't say what kind of surgery, so I'll give a generic answer. Obviously patients and staff don't wear street clothes in the OR. The OR staff wear scrubssuits, no rings or jewellery, have hairnets/caps and wash their hands frequently. The actually surgical team does a more thorough wash, and then dresses in sterile gowns, gloves and masks. The patients are usually nude under a hospital gown. The area of the surgery is exposed and cleaned, and these days then draped with a sterile sticky film with a window of the appropriate size for the surgery. Often a urinary catheter will be placed to keep the bladder empty during surgery. All the surgical team sees is the area they are operating on.
Why do most Chinese people wear face masks everywhere in the world (airports, out and about) when not all air is polluted? Can they not tell it’s OK, as no one else is wearing masks?
Can't comment for all use cases, but from what I've seen - people in Hong Kong and Taiwan wear face masks because :They have a cold or the flu, and do not want to spread germs. Context is typically when someone needs to go to work or school - but can not skip it;The wearer is female, out in the general public and doesn't want to risk catching germs from others which she feels may impact her pregnancy;They are about to board a plane, are concerned about the quality of the filtered but recycled air, and in order to reduce risk of catching germs - they wear the mask. This can also be at the airport before boarding a plane, or also on public transport - like on the subway or a public bus;I've also seen before, but the rarest of situations - where it is likely the wearer has just completed a medical procedure and are at the airport, in transit returning from a medical vacation destination like - Thailand or Taiwan, where someone has recently completed an angioplasty (nose job) or some facial plastic surgery - the mask obfuscates the bruising or swelling - so people can't see what has been done;In Hong Kong, if you visit a hospital or senior home - you may also wear a mask to both prevent yourself from spreading germs - even if you are not ill, or to capture from those that are sick as well. Masks are available by the front entrance for you to choose to use in many cases.The pollution use case is actually, in my non data driven opinion, more of a rarity. Scooter riders in Taiwan do wear masks, but these are often cloth and not disposable masks to try to block airborne particle inhalation from vehicle exhaust. Singaporeans or Chinese residents have worn masks during high pollution periods, but I think wearing masks to prevent inhalation of pollutants occurs less prominently than the context where individuals wear masks to prevent the individual spread of germs or reducing their own risk to catch them.
Why do patients wear surgical caps on their heads during surgery?
You want to know the real answer? It’s because someone or some entity (to remain unspecified) arbitrarily decided that they wanted to legislate cap-wearing for patients. These same folks have been trying assiduously for several years to force surgeons to wear standard bouffant caps rather than the traditional skull caps. These decisions have been made without a shred of medical evidence to support a change in prior practice. In fact, regarding skull caps for surgeons, evidence has recently displayed that changing to bouffant caps does not seem to impact infection rates.Mandatory Change From Surgical Skull Caps to Bouffant Caps Among Operating Room Personnel Does Not Reduce Surgical Site Infections in Class I Surgica... - PubMed - NCBISometimes people just like to make rules for the sake of making rules.
Is it normal for dental implant surgery to hurt post op?
It's probably not abnormal. Depends on a lot of factors. Was the tooth recently extracted? If so there may be some residual trauma from that. Is the dentist who did the implant competent in implants? That will make a lot of difference. Is there a lot of swelling around the implant site? Need more info to determine if your situation is normal or not. Make sure you don't have an infection at the site. Was sterile procedures practiced like gowns, masks, hair nets, etc. I've had three done and I don't remember any pain afterwards. If there was pain it was easily treated with over the counter med since I never had a prescription filled. I don't even think my dentist offered a prescribed pain med. Mine was done by a perodontist who specializes exclusively in surgery and implants.
