Wounds and healing 6, Primary and secondary healing

[@cristianolionelibrahimeden786]

I'm a Vietnamese medical student, after listening this lesson, all I have to said that it is incredibly easy to understand. Thank you so much and wish you have a lot of health!

[@emeldaoginga2008]

The best teacher to listen too

Currently experiencing healing by secondary intent after cyst removal surgery in my underarm got infected after healing by primary intent. Thank you for giving me this information and reassuring me that this open wound I have is semi-normal!

[@leisterfamilyleister1500]

Wow! Dr. Campbell you are an amazing teacher.

[@traceycook4114]

Thank you Dr John, I’m dealing with a recurrent pilonidal sinus wound with my son. His mobility is reduced and he is doubly incontinent. The sinus opens spontaneously once inflammation builds up from body hair. Unusually It’s been open these past 7 months and because of Covid I’ve had little or no input from GP (as it’s been impossible to contact them) until recently when it required antibiotics as it began to smell fishy. Since viewing your videos I’ve been spraying the pocket type wound with previously boiled salt water gauze, drying with gauze and packing it with a ribbon dressing and it’s finally beginning to respond and the wound has become much more shallow with (what I now know is) granulation tissue. I was worried at first because I thought the granulation tissue was a bad thing! Now I realise it’s where it’s healing. I’m now going to add in a daily recommended dose of vit C and Zinc to his limited diet.

[@9907007013]

I m facing same sinus issue. My wound deeper 2CM and 3 CM wider. Help me on fast tissue recovery methods?

Thank you so much for sharing this information! I got struck by a car and had a head wound treated by suture. After removing the sutures, the nurse discovered a 2 cm whole under the sealed surface...I was really worried about healing, but after watching your video, at least I know what I need to worry about, and it'd make the communication with doctors easier. I really wish I could get better soon!

[@Campbellteaching]

Yes, I also wish it will get better soon. Are you now being well treated by health care professionals?

[@hopezhang8278]

@@Campbellteaching Thank you for replying! Yes, fortunately I live quite close to a hospital. I think last time the nurse put a vaseline gauze into the hole. They will change the dressing today.

I actually really like this Dr.

[@secondbestpriest]

I have a deep second degree burn on my leg so this has helped me to understand the healing process.

[@girlingreenscarf7766]

primary healing - approximate the edges of the wound (direct closure with two sides of injuries) secondary healing - loss substantial amount of tissue - leave the wound open - granulation will occur from the edges of the wound and progressing filling the tissue loss

[@squierstrat26]

Great lecture

[@Sarah-dn1tz]

[@bayanabdulazizalghafis1849]

thank u so much , u are a good teacher , keep going .

[@strawberryrhubarbpie]

this was great, studying for a quiz in my fundamentals of nursing course. however they mentioned the third process being called tertiary intention, where the wound is left open on purpose to control infection and is closed at a later time creating a larger and deeper scar.

[@wadiefaridhaddad7429]

Prof Donald Wilhelm NSW FOUNDING PROF pathology 1969 75 Wilhelm's research interests were recorded in some fifty-six papers and seven chapters of books. He made three lasting contributions to understanding of the inflammatory response. First, he analysed the dynamics of vascular permeability changes (vessel leakage), brought about by injury. He stressed the use of mild stimuli to cause minimal damage so the detailed cellular events could be readily defined. Secondly, he and Miles, in analysing chemical mediators of inflammation, characterized globulin permeability factor, now recognized as a trigger for bradykinin production. Thirdly, they defined criteria for characterizing chemical mediators from tissues. As an investigator Wilhelm was methodical, industrious and persistent. His friend Trevor Dinning stated that he was 'always a well organised and committed person', who appreciated elegant techniques in the experimental setting where tissue reactions could be manipulated. He liked the clean-cut, well defined experiment illustrated in many of his own studies on vascular permeability changes in inflammation. He was exacting in writing up his papers and those of his students.

[@perfectbunwere9766]

Very interesting

[@TheQwertsy]

great stuff!!

[@_papad8434]

Well apparently I had not one, but multiple doctors who did not know some of this stuff, and did not know how to correctly treat a wound- -specifically a cat bite. Got bitten, and I immediately took an antibiotic that I had in my medicine cabinet. It was midnight, so next day, went to one of those urgent care clinics--you can probably guess which one--they are on practically every corner in the US now. In addition to an antibiotic, they gave me an antimicrobial. Antimicrobial was prescribed for only once a day. That didn't sound right to me, a person of non-medical background. So I asked to make sure. They said yes. Well, they were WRONG! After multiple follow-ups, the second or third DIFFERENT doctor had increased the dosage of the antimicrobial, but by that time it was too late. The wound soon abcessed, popped open, and I squeezed out all the gunk and flushed out what was now a gaping hole in my leg. I went back to the same urgent care, and the different-again doctor literally did not know what to do. He looked at me with a dumbfounded look on his face and told me to go to the nearby emergency center. The doctor there looked at it and said, looks good, you did a great job cleaning it out. I'll send someone in to bandage and wrap it up again. I said no thanks, I'm a pro at that now, because it had been several weeks by then. I asked about stitches, and she was afraid to stitch it up because she was afraid of another abcess. Well the dang gaping hole wasn't healing. So I took some bandage tape and made my own butterfly stitch. Guess what? It started to close up and heal after that...Go figure...Not without a big hard lump of scar tissue underneath though. I am still massaging it out. Dumba$$es! Can you believe that? I paid for that stupid $hit!

[@sumayia3986]

Thank you Dr. Campbell! I have an exam question that I like to hear your opinion about them: 1. Trauma patient has a wound on the thigh that exposes the muscle and nerves below, how will you manage it ? A. Debridement with secondary closure. B. Debridement with delayed primary closure ?

[@sumayia3986]

Also, can we close 8cm diameter wound be delayed primary closure ?

[@Campbellteaching]

Several factors can influence the answer to your question. It the wound on the thigh is relatively narrow and the edges can be approximated, and the wound is relatively clean and free from high energy contamination, then a layered primary closure is certainly an option.

[@Campbellteaching]

However, if there were devitalised tissue that will necrose, then a delayed primary cloister after debridement and wound cleaning might be more appropriate.

[@Campbellteaching]

For an 8 cm wound, well it depends on the area of the body effected, and how elastic the involved tissues are. Grafting might be an option in this case.

I have an open wound from surgery to remove a seroma from my left chest (mastectomy 12 months ago). The surgery was 6 weeks ago and the community nurses have been dressing it daily. It’s nice and clean but it’s not healing in a hurry. I had radiotherapy to the area in January this year and have lymphodema. Is there any thing I could do to promote healing? The depth is 4cms ,

[@narendrazinzala8761]

But sir, granulation tissue starts growing from center to peripheral, but you said that from peripheral to center(7:25) ....how ??

[@georgieg6873]

Thank you Dr. Campbell , after searching for information and trying to understand what is going on with my partners Stoma reversal wound healing we now understand why it’s taken so long . Finally after almost 6 months he has gone from having 4 strips of aquacel packing to just 1 of 5cm. However, he does have a slightly red sore area on the very outside edge of the skin so we are wondering if you may have the answer as to why this is . Also , along the way he’s had 2 infections, both E.Coli , is this fairly normal with such a deep wound ?.

Secondary healing is associated with increased fibrous tissue production from fibroblasts

@@Campbellteaching Thank you doctor.

[@Campbellteaching]

@@okk2101 I would say there is also more regeneration in primary healing as there is a shorter distance for cell migration to take place over. Of Course, primary healing can still leave a scar, as you will see form any surgical scar.

Hello Dr. Campbell, I was just wondering what the ideal temperature for wound healing would be ? Or if there is such a thing as an ideal temperature?

[@Campbellteaching]

Yes, the temperature at which cellular enzymes function at their optimum levels, i.e. 37'C

[@misterx8585]

OK, thanks for the answer :) but that sounds very hot...? Do they have temperatures like this in hospital rooms for patients after surgery?

[@Campbellteaching]

No, people would feel too hot, but internal wounds will heal at that normal body temperature, as will wounds in the mouth after dental extractions. Wound cooling is a well know adverse factor in wound healing.

[@misterx8585]

OK, I understand. Thanks for the answer :)
