30
How does this principle of aseptic technique apply to opening?
Only sterile items are used within a sterile field
* need to inspect packaging
* don't contaminate item coming out of the package
* you can contaminate only part of the feild
31
How does this principle of aseptic technique apply to opening?
Sterile persons are gowned and gloved
we are unsterile while opening
32
How does this principle of aseptic technique apply to opening?
Draped tables are sterile only at table level
* while draping table, may not be totallly even but we need to leave it for sterile reasons
* if something ends up over table, it is not sterile and we can't fix it from unsterile (because of the 1 foot min. rule)
33
How does this principle of aseptic technique apply to opening?
Sterile persons touch only sterile items or areas, while unsterile persons touch only unsterile items or areas
* ask yourself: Am I sterile? Is it sterile?
34
How does this principle of aseptic technique apply to opening?
Unsterile persons avoid reaching over the sterile field, while sterile persons avoid leaning over an unsterile area
* an example would be heavy/ expensive items need to wait
* open package away from you
* order: away, side, side, front
35
How does this principle of aseptic technique apply to opening?
The edges of anything that encloses sterile contents are considered unsterile
* think about 1" rule from where item is exposed
36
How does this principle of aseptic technique apply to opening?
The sterile field is created as close as possible to its time of use
we open around 30 minutes before but that may vary greatly
37
How does this principle of aseptic technique apply to opening?
Sterile areas are kept continuously in view
* once we open we create sterile field and need to watch for flies, humans, etc.
38
How does this principle of aseptic technique apply to opening?
Unsterile persons must avoid sterile areas
* really applies to opening
* don't ever go between 2 sterile feilds
* ex: mayo stand and back table
* you can move the furniture
* face sterile feild
* pack on back table always opened first
39
How does this principle of aseptic technique apply to opening?
Destruction of the integrity of microbial barries results in contamination
you are responsible for your packaging
40
How does this principle of aseptic technique apply to opening?
Articles of doubtful sterility must be discarded
* don't risk it
* when in doubt, thow it out
41
Abdominal Cavity
* Largest cavity in the body
* Can be artificially divided into:
* 2 areas
* 4 quadrants
* 9 regions
42
2 areas of the abdominal cavity
1. Abdomen proper
2. Pelvis
\*usually call the whole thing abdomen
43
Quadrants
* Right upper
* bulk of the liver and the entire gallbladder
* hepatic flexure of colon
* Left upper
* most of pancreas and stomach, entire spleen
* spenic flexure of colon
* Right lower
* cecum, appendix (usually)
* Left lower
44
Regions
\*know where they are\*
* Right Hypochondric
* Epigastric
* Left Hypochondriac
* Right Lumbar
* Umbilical
* Left Lumbar
* Right Iliac
* Hypogastric
* Left Iliac
45
Layers of abdomen:
* Skin
* Subcutaneous/hypodermic
* Anterior fascia
* Muscle
* Posterior fascia
* Parietal Peritoneum
* Visceral Peritoneum
46
Skin
* Serves as a waterproof barrier from the external environment and pathogens
* First line of defense
* two main layers (has many layers)
* Epidermis (above dermis)
* Dermis (houses basil which is alive)
47
Subcutaneous layer
* A variable thickness layer composed of adipose tissue
* Since fat dows not heal, surgeons will close a thick subcutaneous layer to limit fluid accumulation and infections in this layer
* will create a dead space if not closed
48
Fascia and Muscles
* for any given muscle or muscle group, there will be a "covering" of fascia which wraps it (or, an anterior and a posterior layer of fascia) these layers are continuous with each other
* fascia is a dense fibrous connective tissue which gives strenth and pulling power to muscles and muscle groups
49
Aponeurosis
* Where fascia extends beyond muscles to form a dense, tendonlike structure which anchors muscles to bone, cartilage, or soft tissues such as other muscle/fascia groups (how it gets its pulling power)
50
Lateral abdominal muscles
* each of these exist as muscle on the right and left side of the body. At midline, muscles are absent but their fascia's aponeuroses are present.
* In order from suface to deep
* External Oblique Muscle
* Internal Oblique Muscle
* Transversus abdominus muscle
51
External Oblique Muscle
* Largest and most superficial of three lateral abdominal muscles
* fibers run medially and inferiorly (hands in pockets)
52
Internal Oblique Muscle
* underlies external oblique muscle
* fibers fun opposite external oblique, superio and lateral
* forms an X
53
Transversus abdominus
* Deepest of lateral three muscles
* fibers run transversley (horozontily)
* forms a girdle around sides at waist
54
Medial abdominal muscles
* paired rectus abdominus (right and left)
* thicker than lateral three muscles
55
Rectus abdominus muscles
* extend from pubis to ribs/sternum
* only medial muscles of the abdominal wall
* fibers fun longitudinally
* six pack
* needs reinforcement
* wall with raphes to hold ogans in
56
Fascia of the abdomen
* the lateral three abdominal muscles' fascia all merge to become a very dense aponeurosis medial to the muscles
* these aponeuroses comprise three structures:
* rectus sheath
* linea alba
* raphes of the "six pack"
57
linea alba
* the "white line" divides right and left rectus muscles. so at midline, there is no muscle present, only a very thick aponeurosis
58
Surgical notes on muscle
* skeletal or voluntary muscle in excitable therefore if not paralyzed it will twitch when touched with bovie
* muscle always heals fastest when divided in the direction of its fibers
* generally the term closing fascia means closing posterior fascia, muscle, and anterior fascia as one layer
59
Peritoneum
* serous membrance of the abdomen (double layer)
* parietal portion is breached in surgery
* visceral portion is outer layer of abominal organs and other structures
* visceral and parietal are continuous with each other
* visceral peritoneum is very complex (carries own nerve supply) and folds upon itself to make many different structures
60
Notable structures of visceral pertoneum
* the omenta
* greater (bigger)
* lesser
* mesentary
61
Greater omentum
immediately viewable on entering abdominal cavity, impregnated with fat and hangs from greater survature of stomach to protect most intestines
62
Lesser omentum
located superior to greater omentum, attaches to liver and lesser curvature of stomach
63
Mesentary
* when the word "mesentary" is used in the OR, it is usaully in reference to the "webbing" between coils of intestine
64
The GI tract
| (alimentary canal)
* donut analogy
* hole-unsterile (unsterile mouth to anus)
* bread of donut-sterile
* consists of esophagus, stomach, small intestine, large intesting, rectum
* 4 layers
* mucosa
* submucosa
* muscularis- smooth muscle except for esophagus
* Serosa-viceral peritoneum
65
Esophagus
* leaves thoracic cavity at the esophageal hiatus of the diaphram
* joins stomach at the cardiac orifice aka: gastroesophogeal junction, formally called cardiac sphincter
* abrasion resistant
* muscularis is made of skeletal muscle in its superior third to allow for voluntary swallowing
66
Stomach
* Primary function: digestion of food
* protection against acids
* muscularis has an extra layer
* when stomach empty, mucosa and submucosa form folds called rugae
67
Stomach regions
* cardiac region
* fundus (part of cardiac region)
* body
* pyloric region
* pyloric antrum
* pyloric canal
* pyloric sphincter **(true sphincter before it heads to duodenum)**
* greater curvature
* lesser curvature
68
The small intestine
* primary function: absorption of nutrients
* divisions in order:
* Duodenum
* Jejunum
* Ileum
69
Duodenum
* shortest segment of the samll intestine (25cm long)
* **performs the majority of absorption in small intestine**
70
Jejunum
* mid section of the small intestine
* about 2.5m long
* in some people **may contain Mechel's diverticulum**
71
**Meckel's diverticulum**
* most common anomaly of the GI tract
* may become inflamed like appendix
* **Rule of 2's**
* 2% of population
* 2 feet proximal to ileocecal valve
* 2 inches in length
* 2% are symptomatic
* 2 years: common age of symptomatic patients
* Boys are 2X more likely to present than girls
72
Ileum
* terminal section of small intestine
* about 3.6m long
* joins large intestine at ileocecal valve
73
The large intestine
* **primary function: reabsorb water as it stores, packages, and eliminates waste**
* colon
* distinct feature: haustra
* proximal end: cecum, at posteriomedial surface is usually the vermiform appendix
74
Divisions of the Large intestine
* Ascending colon
* hepatic flexure
* Transverse colon
* splenic fexure
* Descending colon
* Sigmoid colon
* Rectum
75
The liver
* largest gland in the body
* performs many funtions: excretory, metabolic, regulatory, storage, synthesis, removal/detox
* 2 lobes visible anteriorly: R or L
* dual blood supply
* **connected to gallbladder and pancreas via bile ducts**
76
The gallbladder
* Primary function: to store and concentrate bile that the liver makes
* lies in a declivity on posterior aspect of liver called the gallbladder fossa
77
Pancreas
* Endocrine function: works with liver to create homestatic blood sugar levels
* Exocrine function: produces digestive enzymes and juices
* "wrapped" by duodenum
78
Spleen
* sits posterior/lateral to sotmach
* in Left Upper Quadrant
* stores about a cup of blood products
* 4 main functions
* site for immune proliferation, surveillance and response
* stores breakdown products of RBCs
* RBC production in the fetus
* Platelet storage
79
Kidneys
* Primary function: filter blood
* Located retroperitoneally, needs more cushioning than other organs of the abdomen (sits outside the peritoneal cavity
80
Ureters
cross from abdomen proper into pelvis, eventually leading to the bladder
81
the adrenal/suprarenal glands
* sit atop kidneys and share some of their cushioning layer
* Primary function: to produce and excrete corticosteroids and catecholemines
82
Factors influencing type of incision to make
* ease and speed of entry
* maximum exposure
* minimum trauma
* least postoperative discomfort to the patient
* maximum postoperative wound strength
83
3 methods of breaching muscle
1. Cut- incise across direction of muscle fibers; most traumatic
2. Split- make opening by separating the muscle in the direction of its fibers
3. Retract- at midline only, an incision can be made in linea alba and muscles are retracted laterally
84
Longitudinal midline incision
* simplest to perform
* **easiest & fastest--Trauma**
* offers good exposure
* from sternal notch to symphisis pubis, laterally around umbilicus
* follows linea alba
* not a strong incision; wound dehiscence (fall apart) is high
85
Uses for longitudinal midline
* emergency laparotomy
* colon resections, small bowel, colostomy, AAA (abdominal aortic anurism)
* Proximal: bleeding ulcers, gastrectomy, upper quad organs
* Distal: Pelvic surgery, bladder, prostate, ect.
86
Paramedian incision
* another vertical incision
* about 4cm lateral to midline on right or left side
* rectus is either split vertically or retracted laterally
* good exposure to organs in that quadrant
* limits trauma, avoids nerve injury, easily extended, results in firm closure
87
Uses for paramedian incision
* pancreatic procedures or (more rare) biliary tract in upper right quadrant, sigmoid colon in lower left
* don't use very often
88
Umbilical Incision
* AKA subumbilical incision
* a curvilinear incision just below the umbilicus
* previously used for umbilical hernias only, **a smaller version of this incision is used for Hassan Trocar Placement**
89
Mc Burney's point
* (oblique)
* 2/3 of distance from umbilicus to anterior iliac spine in R lower quadrant or
* about 2 fingerwidths medial to inguinal crease
90
Mc Burney's incision
* **8 cm, oblique (angled), muscle splitting incision**
* goes through Mc Burney's point and extends laterally and superiorly towards right flank
* **changes direction to split the "lateral three" muscles**
* **not a whole lot of vision**
* **almost always perfomed on right side for appendix (open appendectomy)**
* "one hit wonder"
91
Inguinal incision
* **inguinal crease**
* **on right or left side**
92
Uses for inguinal incision
* **Primarily: inguinal herniorraphy (males)**
* Also used for: femoral hernia (females), varicocelectomy, hydrocelectomy--men, orchiectomy (cancer)
93
Subcostal incision
* oblique incision that can be made on the right or left side
* at muscle layer, the external oblique is cut, the internal oblique and rectus may be divided or retracted
* limited exposure
* strong closure
* good cosmetic result
* very painful post-op to patient
* decreased in use since the advent of laproscopic colocystectomy (gallbladder removal)
94
Subcostal Modification
* chevron: usually for liver transplant or resection
* uses for single sides subsotal incision: open gallbladder or other biliary tract, splenectomy
95
Pfannensteil Incision
* a curved transverse incision across the lower abdomen made approximately 1.5 inches above the symphysis pubis
* skin, subcutaneous fat, and rectus sheath are all incised transversley
* incision then changes direction, as rectus muscle is split longitudinally. posterior fascia and pertioneum are breached longitudinally
* provides good exposure to pelvic cavity and good stong closure as well as good cosmetic result
* Uses: all types of pelvic surgery, ex: C-section, TAH, open bladder surgery
* bladder has to be retracted to get to uterus in C section
