PROJECT N (advanced) - How to Tie a Figure-8 Suture
This is a project that you will not find on The Apprentice Doctor® "How to Stitch-Up Wounds" Suturing Course CD-ROM.
So if you already have the Suturing Course, this is for you. If you do not have your own set, you probably won't follow what we're talking about below. If you would like to complete this project and understand all the words and concepts covered in it, I strongly recommend you consider ordering a kit for yourself.
"Here's How to Combine a Subcutaneous Suture With an Interrupted Suture in a Single Figure 8 Suture..."
INFORMATION
When should this technique be used?
- Patients who are hypersensitive or allergic to commonly used resorbable suture materials (resorbable materials are absorbed over time by the body and do not need to be removed by a medical practitioner)
- Dehiscence of a previously sutured wound (dehiscence is when a wound opens again after the sutures are removed)
- Closing a skin wound where uneven margins or a dog's ear defect is anticipated e.g. a round/elliptical defect
- Some operators use the figure 8 suture as the suturing method of choice when suturing skin wounds/lacerations
REQUIREMENTS
1. The Suture Kit
1.1. Tissue forceps
1.2. A suture needle with an eye
1.3. Suture thread
1.4. A needle holder
1.5. Imitation skin
2. Good lighting
STEP 1
Use the needle with suture material attached, clipped to the needle holder (see Project 2 and 3 on the CD-ROM)
Use the imitation skin (see Project 4) with the ±7 cm (2,5 inch) cut representing a surgical incision or a laceration in the skin.
You'll start the suture in the region of one of the positional markings on the laceration on the imitation skin, on the far side.
Evert the far side of the laceration with the tissue forceps and insert the needle between five and ten millimeters (about a quarter inch) away from the wound edge.

STEP 4
Take a bite in the depth of the subcutaneous tissue on the near side, twisting the needle to let the needle-tip emerge just below the dermis.

Now mirror the bite on the far side allowing the needle to emerge in the depth of the sub-cutaneous tissue

STEP 6
Place the last section of the suture by penetrating the tissue on the near side just below the dermis, with the needle facing upwards. Allow the needle tip to emerge about three millimeters away from the edge of the wound on the near side.

STEP 7
Tie an "Instrument Square Knot" (see "Project Epsilon") or a Surgeons Knot (see "Project Zeta"). Cut both ends of the suture leaving at least three millimeters of suture material beyond the knot.
STEP 8
Place a second figure-8 suture about three millimeters to the right of the first suture by repeating Steps 4 and 5.
Follow with another couple of figure-8 sutures until you have closed the laceration.
When all is said and done, this is the path of the suture. In top left, then bottom right, then bottom left, then out top right.

POINTS OF INTEREST
What are the advantages of this suturing technique?
- It is removable
(traditional subcutaneous sutures cannot be removed and need to be resorbable, in other words it must be made of material that can be absorbed by the body's tissue enzymes) - It allows closure of two layers simultaneously
- Compared with the interrupted stitch, ischemia at the edge of the suture is reduced (ischemia is a reduction in the blood supply to the body tissue)
- Being removable, one avoids burying foreign material in the depth of the tissue, minimizing the chances of developing a stitch abscess or related complications
- This technique enables any length difference between the flaps to be evened up when sutured
- It minimizes "dog's ear" defects
What are the disadvantages of using this technique?
- It is a more difficult technique to master and perform properly compared to the interrupted stitch
- Patients experience slightly more discomfort on stitch removal compared to the interrupted stitch
Conclusion
I've been busy recently converting The Apprentice Doctor® "How to Stitch-Up Wounds" Course into a hard-copy book which will be promoted by a really huge publishing company which I can't name right now.
Professor Lemmer was one of my medical school professors and he was kind enough to write this foreword to my new book...
"In any practical endeavor, from writing a book, to painting a picture, to performing a surgical operation, knowledge of the subject, no matter how profound, can never by itself lead to a satisfactory outcome. A sound grounding in the basic skills of the discipline is an essential prerequisite.
Technical skill is the handmaiden of all knowledge applied to practical ends. In the field of practical surgery, suturing technique is the most basic skill, yet all too often, even for those at an advanced level of surgical training, special courses in surgical techniques are sometimes found to be necessary to make up for deficiencies in earlier training.
Dr Anton Scheepers, a practicing maxillofacial and oral surgeon of many years experience, has reduced the topic of surgical suturing in all its variety to basic step-by-step technique, with comments on wound care, and has presented this in a form that will be both educational and skill-promotive.
This manual can serve as an appetite-whetter for high school students interested in careers in any clinical field, as a revision for medical, dental, veterinary and paramedical practitioners, and - dare one say? - it might even be useful in junior specialist surgical training.
The author is to be commended."

Those of you who have already worked through the "How to Stitch-Up
Wounds" kit, I would like your opinion on this project.
Did you find it
interesting? A bit more challenging than the other projects?

Too Young to Do Anything

Dear Doc,
I'm only ten years old and already am a straight A student. But is there anything else I can do to help me become a Naentologist?

Wow!

I can understand the stitching, the technique, and the reasons, but I'll never do it in a million years, 'cos I'll be spending too much time unconscious on the surgery floor.
Some of your Youtube videos, and E.R and even Grey's Anatomy freak me out when it gets all tense and blood-covered everywhere.
But my point is that I admire and respect what doctors, surgeons and nurses can do.
So, study hard y'all and keep up the great work, Doc!

Thanks

This was quite difficult but I think I managed to do it. you're right it's just like the two methods on the CDROM, only combined. Ill have to keep practicing.
