Abdominal pain associated symptoms questions
N?V?D?C?CP?SOB?back pain?Urinary sx?
females: missed periods, vaginal bleeding or discharge
Abdominal pain questions
Po intake, anorexia, symptoms change with eating, is the pain constant or intermittent, what was the ride to ER like?
Medical history: GERD, history of ulcers
Surgical history: endoscopy, colonoscopy…
Abdominal pain physical exam
PE: mucous membranes, heart and lungs, CVA tenderness,
Lay down: Point where it hurts, check BS, rebound, guarding and peritoneal signs,
Check for testicular torsion
Abdominal pain ddx
appendicitis cholecystitis pancreatitis diverticulitis bowel obstruction mesenteric ischemia bowel perforation kidney stone gastritis gastroenteritis AAA
abdominal pain work up labs?
Abdominal lab set: pregnancy
UA: kidney
CBC: anemia, wbc for surgery prep
chem 10: hypokalemia = ileus, creatinine for CT prep
coags: pre-op lab, early sign of liver disease
lfts: cholecystitis workup
lipase: pancreatitis
vbg with lactate for older patients: screen for mesenteric ischemia
Pain control for abdominal pain
Morphine: frequent titrated doses
0.1mg/kg, 70kg male = 7-8mg
safer more conservative dose: 4mg IV, may repeat Q15minutes for 3 total doses PRN for pain
Hold for somnolence, hypoxia, or systolic blood pressure under 100
Zofran: 8mg IV with narcotics
Benedryl: for histamine response: 12.5-25mg IV for rash if needed
Abdominal pain imaging when required by quadrant?
LUQ: rigid abdomen or suspected obstruction
EpiG: rarely needs imagine: US RUQ to look for stones
RUQ: cholecystitis: US for stones or sludge
RLQ: appendicitis: usually iv contrast CT of abdomen and pelvis
suprapubic: UTI
LLQ: diverticulitis: CT with IV contrast
Flank pain: colic pain: kidney stones: CT abdomen/pelvis w/o contrast
If you have an elderly patient with HTN or afib that complains of intense abdominal pain but not a lot of tenderness, that get worse every time they eat: check?
VBG with lactate to screen for mesenteric ischemia
and get surgeons involved early
If the person has had multiple abdominal surgeries and vomiting with diffuse tenderness think?
Bowel obstruction: and CT with PO contrast if they can tolerate their kidneys can tolerate the contrast.
Elderly patient with HTN that present with back pain, abdominal pain, syncope or hematuria think what?
AAA
Have a low threshold to ultrasound patients
Aorta >2cm and symptomatic for AAA = OR immediately
Between 2-5cm and asymptomatic = need follow up
>5cm = surgical consult
OPQRST

Additional questions to ask
Vaginal bleeding, or discharge Missed periods Urinary symptoms Fevers, chills Nausea, vomiting, diarrhea, back pain Pregnancy history Sexual history
Sexual history
Ever had sex
Last time
How many partners
Get parents out of room
DDx female specific abdominal pain
Ectopic pregnancy Threatened abortion Normal pregnancy STDs: gonorrhea, chlamydia, trichomoniasis PID Tubo-ovarian abscess Ovarian torsion Ovarian cyst Bacterial vaginosis, candidiasis
Female patient with:
- Sudden onset of lower abdominal or pelvic pain with nausea or vomiting
What should be suspected
Ovarian torsion
There is such a thing as intermittent torsion
- Negative US does not rule out ovarian or testicular torsion.
- Torsion is a clinical diagnosis, US can be helpful
What is the treatment for gonorrhea and chlamydia?
Standard for of care is to treat for both even if only treat positive for one.
Cervicitis:
- Ceftriaxone 125mg IM, 1g Azithromycin PO 1 dose
- Zofran can be given with for nausea
PID: (cervical motion tenderness)
- Ceftriaxone 250mg IM, Doxycyclin 100mg BID 14days
Shouldn’t have sex for 7 days, and partners should be tested and treated.
Tubo-ovarian abscess
S/s
Eti: usually a severe PID that has gone untreated and formed an abscess
S/s: low abd pain, vag discharge
In cases where suspicious of ovarian torsion, should be suspicious of tubo-ovarian abscess as well.

trichomoniasis
Eti: motile organism on wet prep
s/s: itching, discharge, dysuria, dyspareunia, abd pain rare symptom
Tx: Flagyl, 2g 1 time dose, 500mg BID x 7days
- Don’t drink EtoH while on Flagyl
