Abdominal pain, vomiting, and inability to pass gas/stool can signal a
life-threatening blocked bowel. Understand the causes and why prompt medical
care is vital.
Sometimes known as
intestinal obstruction, it's a serious condition which affects the intestinal system. Digestive
processes are seriously affected causing disturbance of
fluid and electrolyte balance
with shock. Study more by following the outline below:
Outline:
Definition.
A break in the continuity of intestinal lumen is what is referred to
as
bowel obstruction.
Signs and Symptoms:
Slow onset at first, then with increasing intensity with the following signs
and symptom;
-
General weakness of the body.
Causes:
A blocked bowel, also known as an intestinal obstruction, is a serious
medical condition that requires immediate treatment in a hospital. The
specific treatment depends on the cause, location, and severity of the
blockage.
Initial Hospital Treatment:
Upon arrival at the hospital, medical staff will work to stabilize your
condition and address immediate symptoms. This typically involves:
Bowel Rest:
You will be instructed not to eat or drink anything to prevent the
obstruction from worsening.
Intravenous (IV) Fluids:
An IV line will be placed to provide fluids and electrolytes, which
are essential to prevent dehydration and correct any imbalances.
Nasogastric (NG) Tube:
A long, thin tube is inserted through the nose and guided down into
the stomach. This tube helps decompress the bowel by suctioning out built-up
fluid and gas, which can relieve pain, pressure, and vomiting.
Medication:
You may be given pain relievers and anti-nausea medications to manage
symptoms. Antibiotics may also be administered if there is a risk of
infection or if a tear in the intestine is suspected.
Non-Surgical Treatment Options:
If the bowel obstruction is partial or caused by a specific condition, it
may resolve without surgery.
These options may include:
Observation:
In some cases of partial obstruction, the "bowel rest" and NG tube
decompression may be enough to allow the blockage to clear on its own.
Enemas or Colonoscopy:
For blockages in the large intestine (colon), a procedure using a
barium or air enema may be used to both diagnose and treat the obstruction,
particularly in cases of
intussusception
(when one part of the intestine slides into another). A
colonoscopy
may also be used to decompress the area.
Stent Placement:
A doctor can insert a small, expandable mesh tube (stent) into the
blocked area of the intestine to hold it open. This is often used for
blockages caused by tumors and can provide temporary relief to allow for a
planned surgery or for symptom management.
Surgical Treatment Options:
Surgery is often necessary for complete blockages, if other treatments fail,
or if there are signs of tissue death (ischemia) or a closed-loop obstruction, which is a surgical emergency. The type of
surgery depends on the cause of the blockage.
Removing the Obstruction:
The surgeon will locate and remove the cause of the blockage, such as
a tumor, scar tissue (adhesions), or a foreign body.
Resection and Anastomosis:
If a part of the intestine is damaged or has died due to the blockage,
that section will be removed. The healthy ends of the intestine are then
reconnected (anastomosis).
Colostomy or Ileostomy:
If the re-joining of the intestine is not possible or safe, the
surgeon may create a
stoma, which is an opening in the abdomen to which the remaining end of the
intestine is attached. Waste then passes through the stoma into a collection
bag. This can be temporary or permanent.
Post-Treatment Care
After the blockage is resolved, whether by non-surgical means or surgery,
your doctor will likely recommend a special diet. You may need to follow a
clear or full liquid diet initially and then slowly progress to a
low-fiber diet
to avoid another obstruction. Following your doctor's instructions for diet,
hydration, and activity is crucial for a successful recovery.
Nursing considerations:
Nursing Considerations in Blocked Bowel Disease
Blocked bowel disease, or bowel obstruction, is a serious medical condition
where the normal flow of intestinal contents is hindered. It can be caused
by a variety of factors, including adhesions from previous surgeries,
tumors, hernias, or inflammatory conditions. The nursing care for a patient
with a bowel obstruction is comprehensive, focusing on assessment,
intervention, and patient education.
1. Nursing Assessment
A thorough and ongoing assessment is crucial for a patient with a bowel
obstruction. This helps to identify the severity of the obstruction, monitor
for complications, and evaluate the effectiveness of interventions. Key
assessment points include:
Abdominal Assessment:
-
Pain:Assess the location, intensity, and characteristics of abdominal
pain. Pain can be colicky and cramping, and a sudden, severe increase in
pain may signal a complication like bowel perforation.
-
Distension:Measure and describe abdominal distension (e.g., tight,
firm, shiny).
-
Bowel Sounds:Auscultate for bowel sounds in all four quadrants. In the
early stages, bowel sounds may be high-pitched and "tinkling" as the
bowel tries to push past the obstruction. In later stages, they may
become absent, which can indicate an
ileus
or
peritonitis.
-
Vomiting:Note the frequency, color, and amount of vomitus. Green or
bile-stained vomitus is a key sign of an obstruction.
-
Fluid and Electrolyte Status:Monitor for signs of dehydration, such as
dry mucous membranes, decreased skin turgor, and concentrated
urine.
-
Assess for electrolyte imbalances, especially
hypokalemia
and
metabolic alkalosis, which can result from vomiting and fluid shifts into the intestines.
-
Monitor intake and output (I&O) carefully, including nasogastric
(NG) tube output and urine output.
Vital Signs:
-
Monitor for changes in vital signs, such as tachycardia, hypotension,
or fever, which could indicate dehydration, a worsening condition, or
the onset of complications like infection or shock.
-
Bowel Function:Document the time and characteristics of the last bowel
movement and the presence or absence of flatus.
2. Nursing Interventions:
Nursing interventions are aimed at stabilizing the patient, decompressing
the bowel, managing symptoms, and preparing for potential surgery.
Bowel Decompression:
-
A nasogastric (NG) tube is often inserted to decompress the bowel. The
nurse is responsible for inserting and maintaining the NG tube,
connecting it to suction, and monitoring the amount and color of the
aspirate.
-
Keep the patient NPO (nil per os) to prevent further distension and
reduce the risk of aspiration.
-
Fluid and Electrolyte Management:Administer intravenous (IV) fluids as
prescribed to correct dehydration and electrolyte imbalances.
-
Monitor laboratory values such as electrolytes, blood urea nitrogen
(BUN), and creatinine.
-
Pain and Symptom Management:Administer analgesics and antiemetics as
prescribed. Be mindful that opioid use can worsen constipation and
ileus. Non-pharmacological comfort measures like a heating pad (if not
contraindicated) and position changes can also be helpful.
-
Provide frequent oral care to combat the dryness and discomfort
associated with the NG tube and NPO status.
Activity and Mobility:
-
Encourage ambulation as tolerated to help stimulate bowel motility. For
immobile patients, frequent repositioning is important to prevent
complications.
-
Surgical Preparation:If surgery is indicated, the nurse's role includes
preparing the patient for the procedure, which may involve administering
antibiotics, providing pre-operative education, and ensuring informed
consent is obtained.
3. Patient and Family Education:
Educating the patient and family is a key part of the nursing process for
bowel obstruction, especially for preventing future episodes.
-
Signs and Symptoms: Teach the patient and family to recognize the signs
of a recurrence, such as abdominal pain, distension, vomiting, and
inability to pass gas or stool.
-
Dietary Modifications:After the obstruction is resolved, the patient
will be gradually advanced from a clear liquid diet to a low-fiber diet
as tolerated.
-
Educate the patient to chew food thoroughly and eat small, frequent
meals.
-
Depending on the cause, a low-fiber diet may be recommended to prevent
future blockages.
-
Hydration: Emphasize the importance of adequate fluid intake, unless
contraindicated by other health conditions.
-
Activity: Encourage regular physical activity, as it helps promote
healthy bowel function.
Medication Management:
Review all medications, especially those that can cause constipation (e.g.,
opioids).
Discuss the use of stool softeners or laxatives if recommended by the
healthcare provider.
Follow-Up Care: Stress the importance of keeping all follow-up appointments
and seeking immediate medical attention if symptoms of a blockage return.
