Acute Abdomen

March 2018 | by EMauthor


Abdominal pain represents one of the diagnostic problems in the emergency department. The following points should be kept in mind in the approach to patients with acute abdominal pain. The most important initial assessment depends on proper history and physical examination. In many cases a specific diagnosis can not be reached with examination or the basic investigation. The primary aims of emergency management of acute abdomen are;


Resuscitation of unwell patients

Adequate analgesia of patients in severe pain

Broadly identifying patients with surgical abdomen who needs surgical referral

Identifying patients who need admission for further assessment/ specific investigations


Patients who needs opiate because of the severity of the pain should not be discharged but should always be referred to the surgical team. This policy has been agreed with the surgical directorate. Do not miss ectopic pregnancy as a cause of abdominal pain in all women of child bearing age, all these patients should have urine B HCG testing


Initial assessment


History, detailed about the pain and any associated symptoms and includes previous episodes, co-morbid conditions, drugs. Physical examination, general and abdominal examination, with particular attention for signs of peritonism, masses, aortic aneurysm, hernial orifices and should always include a digital rectal examination with patient’s consent.


Investigations


Urine dipstick and sample for MSU, test for pregnancy for all women of child bearing age

Bloods for FBC, Glucose, U&Es, LFT, Amylase when relevant

ECG for patients with upper abdominal pain above 35 years of age

Radiology should include

Erect chest x-ray when you suspect visceral perforation

Supine abdomen for bowel obstruction or generalised peritonitis


X-rays are not indicated for the following


Constipation

Acute appendicitis

GI bleeding

Gastroenteritis

Gall bladder disease


Management  


For the unwell or very sick patient manage Airway, Breathing and Circulation.

Obtain venous access with a large bore cannula and obtain blood for necessary investigations

Give adequate analgesia, the best for patients with severe abdominal pain are IV opiates

Consider the need for IVF for patients who may be dehydrated eg vomiting or obstruction

Make sure to exclude possible medical causes of abdominal pain

Refer all patients with possible surgical abdomen to the surgical team.


Indications for referral


Abdominal pain with possible surgical cause in the differential diagnosis

Possible infective process like diverticulitis or appendicitis

Cholecystitis but not gall bladder colic

Intestinal obstruction

Suspicion of visceral perforation

All patients who required IV opiates for control of abdominal pain

Suspicion of mesenteric ischaemia


Pitfalls in management of abdominal pain


Rigidity may be absent in the elderly even in presence of serious intra-peritoneal sepsis

Fever may be absent in people with intra-peritoneal sepsis especially the elderly

Normal WCC does not exclude serious intra-peritoneal sepsis
