Appendicitis

Introduction:

Inflammation of the vermiform appendix (a blind pouch located near the ileocecal
valve in the right lower quadrant of the abdomen) is known as appendicitis. It may
be due to obstruction from stool. The mucosal lining of the appendix continues to
secrete fluid, which will increase the pressure within the lumen of appendix, caus-
ing a restriction of the blood supply to the appendix. This decrease in blood sup-
ply may result in gangrene or perforation as the pressure continues to build. Pain
localizes at McBurney’s point, located midway between the umbilicus and right
anterior iliac crest. Appendicitis may occur at any age, but the peak occurrence is
from the teenage years to 30.

PROGNOSIS

Rupture of the appendix is more likely to occur in acute appendicitis within the
first 36 to 48 hours. Symptoms of peritonitis (inflammation of the peritoneum—
the membrane lining the abdominal cavity) may occur as a complication of appen-
dicitis. Rapid diagnosis and surgical intervention are necessary to avoid rupture of
the appendix.

SIGNS AND SYMPTOMS

• Rigidity of the abdomen (abdomen feels more firm when palpating)
• Fever due to infection
• Nausea, vomiting, loss of appetite
• Right lower quadrant pain that improves with flexing the right hip suggests
perforation

TREATMENT

• Surgical removal of the appendix—appendectomy (may be done via laparo-
scopy or open laparotomy).
• NPO—nothing by mouth to avoid further irritation of the intestinal area, and
prep for surgery.
• Intravenous fluids until diet resumed.
• Pain medications after surgery as needed; pain medication is used cautiously
preoperatively to maintain awareness of increase in pain due to possible rup-
ture of appendix.
• Antibiotics postoperatively if needed.

NURSING DIAGNOSES


• Acute pain
• Hyperthermia
• Nausea

NURSING INTERVENTION


• Monitor vital signs for fever, increased heart rate, respiratory rate, and decrease
in blood pressure.
• Assess pain level for changes.
• Monitor surgical site for appearance of wound, drainage.
• Monitor abdomen for distention, presence of bowel sounds.
• Monitor intake and output.
• Monitor bowel function. Bookmark and Share

  1. It is no secret that I have a very deep and personal relationship with God. I have pushed and resisted that relationship this past year through all the bullshit I have had to go through living with Herpes but once again, God is bigger than my stubbornness and broke through that outbreak cold sore and all I had Genital Herpes. For me personally, hearing over and over how I am not good enough has really invaded my mind in the worst way possible. I completely shut down and I was just waking up like is this how life going to end this temporary herpes outbreak “fuck everybody with herpes if you know what I mean” but let's be honest here...
    It is cowardly to say no to herbal medicine. It is fear based. And it is dishonest to what my heart wants. Don't build a wall around yourself because you are afraid of herbals made or taking a bold step especially when it's come to health issues and getting cured. So many young men/ women tell me over and over that Dr Itua is going to scam me but I give him a try to today I feel like no one will ever convince me about herbal medicine I accept Dr Itua herbal medicine because it's cure my herpes just two weeks of drinking it and i have been living for a year and months now I experience outbreak no more, You can contact him if you need his herbal medicine for any such diseases like, Herpes, Parkinson, Diabetes, Hepatitis, Syndrome, Cancers, HIV, Epilepsy, Infertility, and any kind of disease & Infections Love Spell,. Email..drituaherbalcenter@gmail.com then what's app.+2348149277967.... My advice to any sick men/women out there is simple... Be Always an open book. Be gut wrenching, honest about yourself, your situation, and what you are all about. Don't hold anything back. Holding back will get you nowhere...maybe a one way ticket to lonelyville and that is NOT somewhere you want to be. So my final truth...and I'm just starting to grasp this one..
