Procedure for suturing wounds or hecting actions - a brief medical study martinshaji
Wound closure techniques have evolved from the earliest development of suturing materials to comprise resources that include synthetic sutures, absorbables, staples, tapes, and adhesive compounds. The engineering of sutures in synthetic material along with standardization of traditional materials (eg, catgut, silk) has made for superior aesthetic results. Similarly, the creation of topical skin adhesives (the monomer 2-octyl cyanoacrylate), surgical staples, and tapes to substitute for sutures has supplemented the armamentarium of wound closure techniques. Aesthetic closure of a wound, whether traumatic or surgically induced, is based on knowledge of healing mechanisms and skin anatomy (see the image below), as well as an appreciation of suture material and closure technique. Choosing the proper materials and wound closure technique ensures optimal healing.
this is a brief study on different suturing techniques and tools used

Recomendações da OMS sobre cuidados maternos e neonatais para uma experiência pós-natal positiva.
Em consonância com os ODS – Objetivos do Desenvolvimento Sustentável e a Estratégia Global para a Saúde das Mulheres, Crianças e Adolescentes, e aplicando uma abordagem baseada nos direitos humanos, os esforços de cuidados pós-natais devem expandir-se para além da cobertura e da simples sobrevivência, de modo a incluir cuidados de qualidade.
Estas diretrizes visam melhorar a qualidade dos cuidados pós-natais essenciais e de rotina prestados às mulheres e aos recém-nascidos, com o objetivo final de melhorar a saúde e o bem-estar materno e neonatal.
Uma “experiência pós-natal positiva” é um resultado importante para todas as mulheres que dão à luz e para os seus recém-nascidos, estabelecendo as bases para a melhoria da saúde e do bem-estar a curto e longo prazo. Uma experiência pós-natal positiva é definida como aquela em que as mulheres, pessoas que gestam, os recém-nascidos, os casais, os pais, os cuidadores e as famílias recebem informação consistente, garantia e apoio de profissionais de saúde motivados; e onde um sistema de saúde flexível e com recursos reconheça as necessidades das mulheres e dos bebês e respeite o seu contexto cultural.
Estas diretrizes consolidadas apresentam algumas recomendações novas e já bem fundamentadas sobre cuidados pós-natais de rotina para mulheres e neonatos que recebem cuidados no pós-parto em unidades de saúde ou na comunidade, independentemente dos recursos disponíveis.
É fornecido um conjunto abrangente de recomendações para cuidados durante o período puerperal, com ênfase nos cuidados essenciais que todas as mulheres e recém-nascidos devem receber, e com a devida atenção à qualidade dos cuidados; isto é, a entrega e a experiência do cuidado recebido. Estas diretrizes atualizam e ampliam as recomendações da OMS de 2014 sobre cuidados pós-natais da mãe e do recém-nascido e complementam as atuais diretrizes da OMS sobre a gestão de complicações pós-natais.
O estabelecimento da amamentação e o manejo das principais intercorrências é contemplada.
Recomendamos muito.
Vamos discutir essas recomendações no nosso curso de pós-graduação em Aleitamento no Instituto Ciclos.

NVBDCP.pptx Nation vector borne disease control programSapna Thakur
NVBDCP was launched in 2003-2004 . Vector-Borne Disease: Disease that results from an infection transmitted to humans and other animals by blood-feeding arthropods, such as mosquitoes, ticks, and fleas. Examples of vector-borne diseases include Dengue fever, West Nile Virus, Lyme disease, and malaria.
2. Defination
• A surgical suture:- is a material that
approximates the adjacent cut surfaces or
compresses blood vessels.
• Suturing:- is the act of bringing tissues
together and holding them in apposition until
healing takes place.
4/6/2022 2
Dr. Timur Alazazi
3. GOALS OF SUTURING
• Wound edge apposition.
• Provide adequate tension.
• Maintain hemostasis.
• Aid in wound healing.
• Avoid wound infection.
• Produce aesthetically pleasing scare by
approximating skin edges.

5. Needle holder
Parts:
• Working tip/jaws
• Joint
• Shank/body
• Catch mechanism/ratchet
• Grip area/Ring
4/6/2022 5
Dr. Timur Alazazi
6-in. (15-cm) needle holder is usually recommended
6. Needle holder
How to hold
It is held with thumb & ring
finger through the rings &
with the index finger along
the length of needle holder
to provide stability &
control.
4/6/2022 6
Dr. Timur Alazazi
7. Needle holder
Difference between neddle
holder and hemostate
• A hemostat has a longer, thinner
beak compared with the needle
holder
• The faces of the beaks of the needle
holder are cross-hatched to ensure
a positive grip on the needle while
The faces of the hemostat have
parallel grooves that do not allow a
firm grip on the needle.

Dr. Timur Alazazi
9. Scissors
4/6/2022 9
Dr. Timur Alazazi
Dean scissors is the most used one
These scissors have slightly curved
handles and offset serrated blades
that make cutting sutures
easier. Suture scissors usually have
long handles and thumb and finger
rings. The scissors are held in the
same way as are needle holders.
10. Suture needle
Parts:
• tip/point
• body/shaft
• eye/swaged end
Made up :
• Stanless steel “StSt”
• Carbon steel

1. Has no capillary action
2. Less infection risk
3. Smooth tissue passage
4. Higher tensile strength
5. More throws required
Multifilament:-
1. Has capillary action
2. Increased infection risk
3. Less smooth passage
4. Less tensile strength
5. Better knot security
Absorbable :-
1. Degraded by
enzymes,hydrolysis or
phagocytosis
2. Used to hold the edges in
approximation temporarily
until the wound is heal
NonAbsorbable :-
1. Encapsulated or walled off
by fibrosis
2. Used to suture at sites
where tensile strength
need to be maintained
CHARACTERISTICS

4/6/2022 23
Dr. Timur Alazazi
24. Suture material
Selection of suture materials
Do not use dyed sutures on the
skin
Dyed sutures are best visualized in
oral cavity.
Use monofilament on the skin as
multifilament harbor BACTERIA
Non-absorbable cause less
scarring but must be removed
Location and layer, patient factors,
strength, healing, site and
availability all also should be
considered
4/6/2022 24
Dr. Timur Alazazi
25. Suture material
Selection of suture materials
The most commonly used suture needles in dentistry are the 3/8 and 1/2 circle needles.
The 3/8 needle allows the clinician to pass from the buccal surface to the lingual surface in
one motion.
The 1/2 circle needle is traditionally used in more restricted areas; for instance, in the buccal
of the maxillary molars and the facial aspect of the maxillary and mandibular incisors.
Generally in dentistry, the 3/8 reverse cutting needle with a 3-0 or 4-0 thread diameter and
the 1/2 reverse cutting needle with the thinner and more delicate 5-0 or 6-0 thread diameter
are the most commonly used needle and thread combinations,
4/6/2022 25
Dr. Timur Alazazi
26. Suture material
Principle of suturing
The needle should be grasped at
approximately 1/3 of the distance
from the eye & 2/3 from point.
The needle should be pierced the
tissue perpendicular to its
surface(right angle)to make the
smallest possible hole in the
mucosal flap .If the needle passes
through the tissue obliquely, the
suture will tear
The needle should be placed
equidistant (2-3mm) from the
incision line.
4/6/2022 26
Dr. Timur Alazazi
27. Suture material
Principle of suturing
The depth of penetration should
be equal on both side of incision
line.
The needle always passes from –
A. The movable tissue to the
fixed tissue.
B. Thinner tissue to the thicker
tissue.
C. Deeper tissue to the
superficial tissue.
4/6/2022 27
Dr. Timur Alazazi
28. Suture material
Principle of suturing
When placing multiple adjacent
interrupted sutures, they can
usually be spaced about 1 to 1.5 cm
apart.
The tissue never be closed under
tension (The flaps should not be
blanched and there is no ischemia
at the edges when tying a suture)
4/6/2022 28
Dr. Timur Alazazi
29. Suture material
Principle of suturing
Only the long end that is pulled
during knoting and to the opposite
direction . The short end should be
1.5-2 cm long
The knot should be positioned so
that it does not fall directly over the
incision line, because this causes
additional pressure on the wound.
Therefore, the knot should be
positioned to the side of the
incision line.(3-4 mm apart from the
incision line)
4/6/2022 29
Dr. Timur Alazazi
30. Suture material
Principle of suturing
The ends of the suture should be
left no longer than 1 cm.

31. SUTURING TECHNIQUES
Interrupted suture.
1. Simple (Routine) interrupted suture
2. Mattress suture:-
A. Horizontal mattress
B. Vertical mattress
Continuous suture.

FIGURE II-14. An example of placing a
single routine suture after an implant
procedure. A, The needle placed
through the facial papilla, taking care to
engage enough tissue so the suture is
less likely to pull through during
knotting. B, The second pass of the
needle through the undersurface of the
lingual papilla, attempting to engage
the same amount of tissue as engaged in
the facial papilla. If 2 sides of papilla are
lying well positioned before
suturing, many surgeons with make a
single pass with the needle through both
sides, rather than using a second
pass. C, The needle has been brought
through the lingual papilla to the facial
side to allow for knotting. D, Note
that the knot has been positioned to the
facial side of the wound before it is cut.
This keeps it off the wound edge,
to keep it from irritating the patient’s
tongue and, for nonresorbable sutures, in
a position making it easier to
remove.
34. 4/6/2022 Dr. Timur Alazazi 34
Interrupted :- Simple Interrupted
Number of stitches according to the type of flap
1. Envelope flap:- it is held in place with sutures that are
placed through the papillae only. Sutures are not placed
across the empty tooth socket because the edges of the
wound would not be supported over sound bone.
2. If a three-cornered flap :-the vertical end of the incision
must be closed separately. Two sutures are
usually required to close the vertical end properly. Before
the sutures are inserted, a periosteal elevator should be
used to slightly elevate the non–flap side of the incision,
freeing the margin to facilitate passage of the needle
through the tissue .The first suture is placed across the
papilla where the vertical release incision was made. The
remainder of the envelope portion of the incision is then
closed.
42. Removal of the sutures
Skin sutures are removed as soon as tissue healing allows.
Non-absorbable sutures are best removed from the face
after a period of 5-6 days.Tissues such as the scalp may
require a longer period(7-10 days).
Use a disinfecting mouthwash to clean the wound of all
debris.
The suture knot is elevated off the tissue utilizing cotton
pliers.
The suture is cut as close to the tissue as possible in order
to avoid dragging bacteria through the wound.
The suture is then pulled towards the incision line to
prevent dehiscence.
When removing continuous sutures, each section should
be cut and pulled out individually.
If pieces of suture left infection may occur.
