Q

Ingested Foreign Bodies TX

A
  1. Remove immediately if object is in esophagus or EM situation (drooling ,wheezing, strider, SOB, fever, abd pain, sharp, drugs, battery)

Q

Hernia :
Reducible
Incarcerated

Q

Inguinal hernia
Indirect
Direct

A

Indirect : passes from interval to external inguinal ring through the patent process vaginalis and into scrotum
Direct : passes through the weak transversalis fascia in the Hasselbach Triangle

22
Q

SX of Hernia :
Reducible
Incarcerated
Strangulate

A
  1. Soft and can push in
  2. Firm needs painful, no systemic illness
  3. Firm and very painful, systemic illness (fever, N, V), skin changes, impaired BF
23
Q

Strangulated Hernia TX

A

= OR emergency surgery
= IV ABs broad spectrum
= fluid resuscitation
= obtain labs

24
Q

Incarcerated hernia TX

A

Try to reduce and if you cant do surgery

25
Reducible hernia TX
Outpatient surgery follow up
26
ABD Aortic Aneurysm prevalence
= top 15 cause of dearth 85yo-89yo = not common under 60yo = 7% over 50yo
27
Dx ABD Aortic Aneurysm
** when Aortic Diameter is over 3.0cm (normal is 1.4cm-3.0cm)
28
ABD Aortic Aneurysm where is it usually located and risks
1. Below renal arteries before it splits | 2. Smoking
29
ABD Aortic Aneurysm SX
= asymptomatic usually = symptomatic only not ruptured : larger enough to compress structure ——> abd pain, limb ischemia, fever, flank pain…) = symptomatic and ruptured : high mortality, TRIAD : 1. severe ABD or/and back pain 2. Pulsatile abd mass 3. Hypotensive
30
Triad for ruptured Abd Aortic Aneurysm
1. severe ABD or/and back pain 2. Pulsatile abd mass 3. Hypotensive = fast and almost 100% death do something fast
31
Abd Aortic Aneurysm risk factors besides smoking
- age - make - Caucasian - FH - had in past in other vessels - atherosclerosis
32
Abd Aortic Aneurysm ruptured can look like
1. Renal colic 2. Perforated viscous 3. Diverticulitis 4. GI hemorrhage 5. Ischemic bowel = if you think any of these always screen for Abd Aortic Aneurysm
33
ABD Aortic Aneurysm DX and screening
1. 1 time for at risk pt over 65 2. Every 6mo or 1 yr if pt has asymptomatic AAA = CT / US 3. CT with IV contract if stable symptomatic AAA 4. OR no imaging if Hx AAA unstable AAA, CT IV contrast if possible if unstable unknown AAA
34
TX for ABD Aortic Aneurysm
1. Wait and watch if asymptomatic 2. Surgery if over 5.5cm or rapidly expanding - Open or endovascular which is more tolerated
35
Number one cause of death worldwide
Trauma
36
Most trauma to abd is what
Blunt trauma to Spleen or Liver (accidents, falls)
37
ATLS
Advanced Trauma Life Support course for all trauma surgeons, ER doctors = so they know how to approach care for a trauma patient
38
How to take care of Trauma pt
1. Airway maintenance (C-spine control), do you need to intubate 2. Breathing and ventilation 3. Circulation + hemorrhage control (esp abd trauma) 4. Disability/neuro stability 5. Exposure/Environment control (undress pt to prevent hypothermia
39
What other part should you look at for an abd Trauma
Urethral, perinatal, renal, vaginal discharge bleeding or problem
40
Diaphragm Injury
Usually on left side = from blunt high speed MVC accident (abd organs go into chest cavity) = DONY use trochanter when putting in chest tube
41
Trochar is what and what to do in trauma situation
Metal spear used as a chest tube | = dissect down and fell around for contents and then place it in
42
Duodenal Injuries
= unrestrained drivers (frontal impact) = Bicycle handle bar = DO CT with IV and ORAL CONTRAST to see the hematoma in the duodenum
43
Pancreatic Injury
= direct blow to pancreas a giant vert wall = check amylase and lipase levels = CT or ABD and pelvis IV + Oral
44
Genitourinary Injury
= direct blow to back or flank = suspect microscopic hematuria = blood coming out ——> anterior pelvic fracture, problem with ureter, bladder, kidney
45
Hollow Viscus Injury
= sudden braking injury in MVC = Chance fracture should be looked at (from bottom seat belt) = US and CT done
46
Solid Organ Injury
= Liver, Kidney, Spleen = FAST scan for leaks = hemodynamcally stable : general surgeon observation conservative, CT scan = hemodynamically unstable / continued bleeding : OR , laparotomy
47
Pelvic Fractures
= MVC, falls = hypotension + pelvic fracture ——> high mortality = pelvic ring disruption : tear in venous plexus disrupting internal iliac A
48
Death rate of pelvic fractures 1. All 2. Closed book fracture + hypotension 3. Open book pelvic fracture
1. 1 : 6 2. 1 : 4 3. 1 : 2
49
Imaging for trauma
1. Lateral C spine, CXR, AP Pelvis 2. FAST scan 3. CT abd/pelvis + IV (if pt is stable and not in rural place needing trauma surgeon (free fluids, pelvic fracture, pneumothorax) so has to be transferred, that will waste time)*
50
Who gets laparotomy
1. Blunt trauma + hypotension + positive FAST scan ** 2. Diagnostic Perotineal Lavage (DPL) : + , stick catherter in below umbilicus and see if there is blood 3. Gunshots past peritoneum 4. Bleeding, air
51
FAST scan
US that Detect free intraperitoneal fluid (morrises punch, spleen / renal recess , around bladder, pericardial sac)
52
FAST scan views and how to hold it
1. Subxiphoid view : right belo xiphoid and aim to shoulder (see heart) 2. Morrison’s Pouch : right flank RUQ side (hepatorenal view), + = Fluid in between liver and kidney 3. Perisplenic View : left flank LUQ side (fluid between spleen and kidney) 4. Pelvic (retrovesicular view) : look behind bladder, scan longitudinally and transversely by umbilicus
