Lecture 11: Abdominal Pain Readings Flashcards
When does an AAA require repair?
- Symptomatic
- >= 5.0cm
Classic presentation of ruptured AAA
- Older male smoker
- hx of atherosclerosis
- Sudden back/abd pain, hypotension, pulsatile abd mass
- Onset of pain is both severe and abrupt.
What hx might predispose aortoenteric fistulas?
Prior aortic grafting
Duodenum MC location
When do you really start monitoring an AAA?
Once it hits 3cm, refer to vascular to monitor
What is the MC initial misdiagnosis for an AAA?
Renal colic
What bedside study is helpful in identifying unclear AAA?
Bedside abdominal US
Measures diameter only!
You really need a CTA
Goal SBP for ruptured AAA
90 SBP
What two layers is blood pouring between for an aortic dissection?
Between the intima and adventitia
Classic demographic of Aortic Dissection
- Older male (>50y) using cocaine
- Hx of HTN
- CT disorders (EDS, Marfan’s, or CHD)
Stanford classification and Debakey of aortic dissections
- Stanford is just Type A = Ascending, B = descending
- DeBakey is type 1 = both, type 2 = ascending, type 3 = descending.
What kind of murmur can be heard during aortic dissection?
Diastolic murmur of aortic insufficiency
MC XR findings for aortic dissection
- Abnormal aortic contour + widening of mediastinum
- Tracheal deviation
- Displacement of aortic intimal calcifications
Imaging modality of choice for aortic dissection
CT Scan with IV contrast (altho im pretty sure its CTA)
Alternate is TEE
How do we manage HTN initially in aortic dissection?
- Esmolol
- Labetolol
Goals: 100-120 SBP, 60-70 HR
If SBP of 100-120 is not met after BB usage in aortic dissection, what can we use?
- Nitroprusside
- Nicardipine
In elderly patients, what hx is important besides the abdominal pain hx?
- Hx of MI
- Dysrhythmias
- Coagulopathies
- Vasculopathies
What is the most important part in the physical exam for abdominal pain?
Palpation
What combination is pretty confirmatory for peritonitis?
- Rigidity
- Referred tenderness
- Cough pain
Also use a Carnett test!
Who gets a pelvic exam in evaluation for abdominal pain?
Any post-pubertal female
In a patient older than 50 showing pain out of proportion to the PE, what is an important DDx to consider?
Mesenteric ischemia
Generally, what does plain XR look for in abdominal pain?
- Obstruction
- Perforation
- Free air
Generally, what does US look for in abdominal pain?
- Stones
- Fluid build-up
- AAA
What is the MC need for abdominal pain that needs resuscitation?
IV fluids (NS/LR)
If we accidentaly give too much morphine, how can we undo it?
Naloxone
Generally, what is considered an “acute/surgical abdomen”?
- Pain
- Guarding (involuntary)
- Rebound
Overall, what is the purpose of analgesics and antiemetics for abdominal pain?
Making it easier to workup/evaluate the patient
So you can get their PE findings more accurately.
Top 2 RFs for PUD
- H. Pylori infection
- NSAIDs (chronic)
Classic description of PUD
- Burning epigastric pain
- Relieved by ingestion of food/milk/anatacids
- Recurrent pain that awakens patient up at NIGHT
What change in someone with PUD suggests perforation?
Abrupt onset of severe pain
What epigastric pain description is most indicative of GERD?
- Radiating into chest
- Belching
In what population is epigastric pain more suspicious and what condition?
Elderly; it could be an atypical MI
Gold standard for diagnosis of PUD
EGD showing an ulcer
Definitive diagnosis of PUD
What are the alarm features for possible cancer with upper GI bleeding?
- Older than 55
- Unexplained Wt loss
- Early satiety/anorexia
- Persistent vomiting
- Dysphagia
- Anemia
- Abd Mass
- Jaundice
Main 3 drugs used to aid in acid decrease for PUD?
- PPIs (-prazoles)
- H2RAs (-tidines)
- Liquid Antacids
Triple therapy H. pylori eradication
- Omeprazole 20mg BID
- Amoxicillin 1g BID
- Clarithomycin 500mg BID
Quadruple eradication therapy H. pylori
- PPI BID
- Metronidazole QID
- Tetracycline QID
- Bismuth QID
How long is eradication therapy for H. pylori?
14 days
How do you definitively diagnose PUD?
Endoscopy
Anyone with a presumptive dx or alarm features
Mainstay of tx for stable, uncomplicated PUD?
PPI or H2RA w/ liquid antacid for breakthrough.
2 MCC of Acute pancreatitis
- Cholelithiasis
- Alcohol Abuse
What condition can result in secondary pancreatitis?
Severe hyperlipidemia
