Q

Is a sudden or gradual onset of pain more concerning? Why?

A

Sudden onset pain is more concerning due to it being caused by a potential rupture/tear or torsion e.g. ruptured aneurysm, ectopic pregnancy, torsion of testis/ovarye

Q

What is appendicitis?

A

Appendicitis is inflammation of the appendix, it becomes full of fluid and can compress surrounding vessels, compromising blood flow and causing ischaemia and necrosis.

This pressure can escalate forcing bacteria and toxins out, abscesses and peritonitis develop and eventually the appendix will rupture.

Rupture can accelerate peritonitis which can be life threatening

Q

What are the symptoms of appendicitis?

A

Typically starts with central abdominal pain that may come and go. A burst appendix will cause sudden, severe pain

Within hours, pain travels to lower-right abdomen, becoming constant and severe

Positive McBurneys point/Rovsing’s sign

Palpation/coughing/walking can all make pain worse

Other symptoms include nausea, vomiting, lack of appetite, diarrhoea, high temp, flushed face, tachycardia

Check if they have had their appendix removed!!

21
Q

Why does Positive Rovsings sign indicate appendicitis

A

It occurs due to irritation of overlying peritoneum, this pulls on the peritoneum that overlaps the appendix causing referred pain

22
Q

What is pancreatitis?

A

Pancreatitis is inflammation of the pancreas, it can be acute or chronic

Causes include gall stones, alcohol, idiopathic cause

Gall stones can become stuck at the entrance to the duodenum, blocking the pancreatic duct and triggering pancreatitis

With this, enzymes that digest food are inactive in pancreas but can become active and auto-digest pancreas

It is a medical emergency, mortality increases with age

23
Q

What are the associated complications of Pancreatitis?

A

Acute respiratory distress

Diabetes can develop

Infection

Shock

Renal failure

Malnutrition

24
Q

What is Diverticulitis?

A

Bulging pouches in the intestinal wall called diverticula can become inflamed and infected. This often occurs due to faecal matter becoming stuck in the pouches

25
Q

What are the symptoms of Diverticulitis?

A

Symptoms include abdominal pain, bloating and a change in normal bowel habits

Pain associated with diverticulitis is constant and severe. Can normally start below umbilicus before moving to lower left quadrant

Other symptoms include high temp <38, lethargic, nausea and vomiting.

26
Q

What is Cholecystitis?

A

Acute inflammation of the gallbladder

It happens when bile becomes trapped and builds up in the gallbladder. In most cases this happens when solid lumps (gallstones) block the tube that drains bile from the gallbladder.

It is a potentially serious condition that usually needs to be treated in hospital

27
Q

What are the symptoms of Cholecystitis?

A

Main symptom is sudden, sharp pain in the upper right quadrant of the abdomen and can spread to the right shoulder

Positive Murphys sign, also seen in acute cholecystitis.

To examine, pressure on upper right quadrant, deep breath, during exhalation will catch on edge of fingers and cause pain.

Symptoms include: High temp, nausea and vomiting, sweating, loss of appetite, jaundice, bulge in the abdomen, clay coloured stools due to lack of bile

More common in fair skinned women, advancing age, obesity, rapid weight loss or pregnancy/hormone replacement therapy

28
Q

What are kidney stones?

A

Kidney stones are lumps that can develop in one or both kidneys causing severe pain known as renal colic.

These lumps are crystals formed by waste products in the blood

29
Q

What are the symptoms of kidney stones?

A

Symptoms include persistent ache in lower back, sometimes felt in the groin - men many have pain in testicles/scrotum

Periods of intense pain in back or side of abdomen, may last for minute or hours

Feeling restless and unable to lie still

Other symptoms include: Nausea, increased urination, blood in the urine and pain during urination

30
Q

What is peritonitis?

A

Peritonitis is a life threatening condition caused by the peritoneum becoming infected.

It can also damage the internal organs that the peritoneum covers.

31
Q

What are the symptoms of peritonitis?

A

Extreme thirst, vomiting, fatigue, bloating, constipation, fever, diarrhoea, low urine output, nausea, inability to pass gas.

Likely to be tachycardia, increased RR and have a rigid abdomen, will need pre-alerting to ED.

The rigid abdomen will feel solid due to bacterial fluid pooling, hard to palpate and any movement that adds pressure will result in significant pain

If the pain eases and comes back suddenly this is a red flag!

The Pt will be dehydrated, low BP, look very unwell, low temp, reduced GCS, could be hypoxic,

32
Q

What is intussusception?

A

Intussusception is a serious condition in which part of the intestine slides into an adjacent part of the intestine. This telescoping action often blocks food or fluid from passing through.

33
Q

What is intussusception?

A

Intussusception is a serious condition in which part of the intestine slides into an adjacent part of the intestine. This telescoping action often blocks food or fluid from passing through.

34
Q

What are the symptoms of Intussusception?

A

Very painful, sudden onset of symptoms within 1 day, severe abdominal pain, vomiting (sometimes green), blood stools with mucus in them (like red jelly), abdominal swelling, diarrhoea, signs of dehydration (Reduced urine output, dark urine, dry mouth, not tears when crying)

Can be fatal

Most common in babies under 1 and up to 5 - will cry consistently and nothing will relieve symptoms. Can be due to severe abdominal trauma

Sepsis and shock can occur

35
Q

What is a stomach ulcer?

A

Ulcers in the stomach which can be caused by an infection

36
Q

What are the symptoms of a stomach ulcer?

A

Symptoms include a burning/gnawing pain that develops in your abdomen.

Pain can also travel up the neck and down to the naval or through your back

Pain associated with stomach ulcer is caused by the ulcer itself and stomach acid that comes into contact and irritates the ulcer.

The pain can last from minutes to hours

37
Q

What is an triple A?

A

A triple A is an Abdominal Aortic Aneurysm

It is a bulge or swelling in the aorta, the main blood vessel that runs from the heart down through the chest and tummy.

38
Q

What are the symptoms of a Triple A?

A

Un-ruptured: Pulsating feeling in abdomen, usually near the umbilicus, persistent back pain, persistent abdominal pain. Complete blood pressures on different arms, may be different/abnormal

Ruptured: Sudden and severe pain in middle or side of abdomen. If laid flat, will see bulge (get down to eye level), In men, pain can radiate down to scrotum, will lose femoral pulse, become mottled and pale in legs very quickly

Other symptoms include: Dizziness, sweaty and clammy, tachycardic, shortness of breath, feeling faint, LOC, Cardiac arrest.

This would need a pre-alert.

39
Q

What is G.O.R.D?

A

G.O.R.D is Gastroesophogeal Reflux Disease

It is a general term to describe the range of situations - acid reflux, with or without oesophagitis

It is caused by acid refluxing back into the oesophagus through a poorly functioning sphincter

Pressure changes causing gastric secretions to irritate the oesophagus - certain foods, alcohol, nicotine, existing hiatus hernia, obesity and pregnancy

40
Q

What are the symptoms of G.O.R.D?

A

Epigastric pain, heartburn, intermittent and worse after a meal

Acidic taste in mouth, bloating and belching

Made worse by bending, stooping, tight belts, overweight

41
Q

What is pyelonephritis?

A

Pyelonephritis is an infection in the kidney.

It can develop as a complication from cystitis - bacteria travel up from bladder to infect kidney and requires antibiotics

Most common with recurrent UTI’S

Kidneys can become oedemas and swell, resulting in renal damage from compression of renal artery

42
Q

What are the symptoms of Pyelonephritis?

A

Symptoms include a gradual onset of pain (loin to groin, back to front), Patient appears ill, maybe systemically unwell with pyrexia, vomiting and rigors

43

45
Q

What is a bowel obstruction?

A

A bowel obstruction is where the intestine has a blockage and can cause a back-up of bowel contents.

Can cause bowel ischaemia leading to toxins entering circulation

Can cause dehydration due to unabsorbed water remaining in bowel and vomiting

46
Q

What are the symptoms of a bowel obstruction?

A

Central abdominal pain of a colicky nature

May have distended abdomen

Vomiting/faecal vomiting in high obstruction

Absolute constipation in low obstruction with lack of flatulence

Reduce bowel sounds/movement

Normally hear about 15 bowel sounds in 1 minute, can be either hyperactive or underactive

47
Q

What is Chrohns Disease ?
