Case 1A 19 year old male presents with a two
day history of abdominal pain. He states that at onset, his pain was in the middle of his abdomen, and has since moved to the right lower side. He notes nausea, emesis, anorexia, and a low grade fever. On exam, he has rebound tenderness to the RLQ, pain with leg movement, hip rotation, and pain in the RLQ on LLQ palpation. How often do perfect clinical cases like this present to the ED?

Introduction6.7% of ED visits are for abdominal painHistory, physical, labs often not as
helpful as Cope would have you believe.Goal is to detect life-threatening causes
of abdominal pain, if not to make a solid diagnosis.
The Elderly, the Young, and those who cannot get follow-up are high risk groups that may require further study and admission even in the absence of abnormal findings.

PainVisceral
◦Stretching of unmyelinated fibers that innervate walls or capsules of organs.
◦Crampy, dull, achey pain.◦Localized to a sensory level, but often
midlineParietal
◦Irritaion of myelinated fibers in the parietal peritoneum
◦Localizable, causing guarding, rebound◦Patients like to stay still

PainReferred pain
◦Pain that is remote from the source◦Caused by developmental
embryology◦Normally ipsilateral◦Boaz Sign?◦Kehr’s Sign?◦Where might renal pain get referred
to?

PrioritesFinding critical illness and
stabilizing◦Normal vitals signs are not excluding
for critical illness◦Resuscitate and diagnose at the
same time 2 LB IV’s, O2, monitor CBC, BMP, Coag, T&S
◦Don’t neglect to do a thorough exam.
◦Intensity of pain bears no relation to severity of illness.

PrioritiesFinding critical illness
◦Red Flags Extremes of age Rapid onset of severe pain Abnormal vitals Dehydration Pallor, vomiting, diaphoresis
◦Shock most likely hemorrhagic if of rapid onset
◦Temperature least helpful of vitals

HistoryPertinent illnesses
◦DM◦HTN, CAD, PVD◦Liver or Renal disease◦Surgical history◦Sexual history◦Meds/IUDs◦Any trauma◦Any similar episodes?

Physical ExamUncover as much as necessary
◦Check for that perirectal abscess and Fournier’s
First, inspect◦Distended, stigmata of liver disease,
surgical scars? Masses?Then, auscultate
◦Low sensitivity!
![Page 11: Abdominal Pain](https://reader036.vdocuments.us/reader036/viewer/2022070422/568163f3550346895dd57add/html5/thumbnails/11.jpg)
Physical examFinally palpate
◦Have the patient point to where it hurts
◦Hit that area last◦May have patient bend knees if they
cannot otherwise relax abdominal wall muscles
◦Interrater reliability 60-92% for abdominal tenderness (Yen, K, et al, Arch Ped Adol Med, 2005, Apr, 159(4):373-6)
◦Consider early use of Ultrasound at the time of palpation.

LabsShould be diagnosis specificConsider pattern of painHow likely is it that an LFT will
help someone with LLQ pain?Preg test – always necessary for
women of childbearing age and capability

LabsCBC
◦WBC least useful in the panel◦Hemoglobin – anemia from what?
Can be useful for trending◦Platelet counts – liver disease, ITP,
HEELPBMP
◦Renal function most important◦Calcium◦CO2 level as a flag for metabolic
acidosis

ImagingUltrasound
◦Many choose to use ultrasound like a stethoscope
◦Modality of choice for RUQ pain◦Recommended as first line for flank
pain, RLQ pain in kids – operator dependent
◦Modality of choice for pelvic pain

ImagingPlain films
◦Useful only for Free air Obstruction/volvulus Pneumonia
◦Overall, low value

ImagingCT
◦High sensitivity◦High specificity◦High radiation risk◦High cost
Elderly, immune compromised, those who you are uncertain, but look ill.
PO contrast – bowel obstruction, bowel mass
No contrast – renal stone, renal insufficiency
