EXPLORATORY LAPAROTOMY AND TRANSVERSE LOOP COLOSTOMY
1. EXPLORATORY LAPAROTOMY
It is a method of abdominal exploration, a diagnostic tool that allows
physicians to examine the abdominal organs. The patient is usually placed
under general anesthesia for the duration of surgery. The advantages to
general anesthesia are that the patient remains unconscious during the
procedure, no pain will be experienced nor will the patient have any memory
of the procedure, and the patient's muscles remain completely relaxed,
allowing safer surgery.
During laparoscopy, organs that might have disease will be explored.
The doctor will examine you using the tools that have been passed through
the incisions. A television will be used to project the images. The surgeon may
take samples (biopsies) from suspicious areas. These will then be sent to the
lab.
*1-4 hours (depending on how hard it is to make a diagnosis)
PRE-OPERATIVE CARE
Do not take aspirin or other anti-inflammatory drugs for one week before
surgery, unless told otherwise by your doctor. You may also need to stop
taking blood-thinning medications. Examples include clopidogrel (Plavix),
warfarin (Coumadin), or ticlopidine (Ticlid). Talk to your doctor.
POST-0PERATIVE CARE
The patient will remain in the postoperative recovery room for several
hours where his or her recovery can be closely monitored.
Monitor for signs and symptoms of:
Bleeding or discharge from the incisions
Fever
Increasing pain or pain that doesn't go away
Nausea or vomiting
Constipation beyond the first few days
Pain or swelling in your legs
Cough or difficulty breathing
Pain or difficulty with urination
2. TRANSVERSE LOOP COLOSTOMY
Transverse loop colostomy is a simple, fast, and relatively easy
procedure used for those patients with pelvic disease in whom a temporary
fecal diversion is needed and who are not candidates for an end sigmoid
colostomy because of medical or technical reasons.
The transverse colostomy is in the upper abdomen, either in the middle
or toward the right side of the body. Some conditions of the colon such as
those caused by diverticulitis, inflammatory bowel disease, cancer,
obstruction, injury, or birth defects can lead to a transverse colostomy.
This type of colostomy allows the feces to exit from the colon before
they reach the descending colon. When conditions such as those listed are
present in the lower bowel, it may be necessary to give the affected portion of
the bowel a rest. A transverse colostomy may be created for a period of time
to prevent feces from passing through the area of the colon that is inflamed,
infected, diseased or newly operated on, thus allowing healing to occur.
There are two types of transverse colostomies: “loop transverse
colostomy” and “double-barrel transverse colostomy.
PRE OPERATIVE CARE
Preparation for colon surgery begins a few days prior to the procedure
unless the surgery is being done on an emergency basis, such as for an
injury or intestinal bleeding. Most patients have undergone a colonoscopy,
sigmoidoscopy, or barium enema to diagnose the disease. These tests
generally are not repeated. Prior to the operation, blood tests, a chest x-
ray, an EKG, and an abdominal CT scan may be ordered.
The colon contains bacteria and waste products that can cause infection if
they leak into the abdomen during surgery and precautions are taken to
reduce this risk. Oral antibiotics are started several days before the
operation is scheduled and the colon must be as empty as possible.
The procedure for colon cleansing depends on the physician, the patient's
health and diagnosis, and the facility where the procedure is being
performed. Generally, for 2 or 3 days prior to surgery, a soft or semi-liquid
diet (i.e., foods that are quickly and easily digested) is ordered. For some
patients, only clear liquids are permitted. These include fruit juice, sports
drinks, clear broth, and gelatin. All patients must go on a clear liquid diet
24 hours prior to surgery. After midnight, the night before surgery, nothing
may be taken by mouth.
Cleansing solutions and laxatives are used to cleanse the colon before
surgery. Patients are given a laxative solution to drink that can cause
severe diarrhea, so they may be admitted to the hospital the day before
the surgery to receive intravenous fluids that prevent dehydration.
If the patient is unable to comply with this regimen, it is necessary to
inform the physician as soon as possible. It may be unsafe to do the
surgery as scheduled and it may have to be postponed.
During this period, it may not be possible to continue prescription
medications. Blood "thinning" medications, including aspirin, must be
discontinued one week before the operation to avoid excessive bleeding
during the procedure.
An informed consent form must be signed acknowledging that the patient
understands the procedure, the potential risks, and that they will receive
certain medications.
The patient is then taken to a preoperative holding area and must remain
in bed except to use the bathroom. An intravenous (IV) is started for fluids
and medication, if one is not already in place. A sedative is given through
the intravenous to induce drowsiness. Anesthesia is administered in the
operating room.
POST OPERATIVE CARE
After surgery, the patient is taken to the postanesthesia care unit (PACU)
and is closely monitored by the nursing staff until the anesthesia wears off.
If no problems are observed in the PACU, the patient is transferred to a
hospital room after about 2 hours.
The catheter that was inserted prior to surgery and the IV remain in place.
The catheter is removed in a day or so, depending on recovery. Food and
fluid cannot immediately be taken by mouth, so the intravenous keeps the
patient nourished and hydrated. Medication is delivered through the IV.
Postsurgical abdominal pain is common, and medication is given to relieve
it. If the pain is unusually severe and the medication does not provide
relief, the doctor must be notified as soon as possible because this may
indicate a complication.
Nothing may be taken by mouth until it is certain that normal bowel
function has resumed. This is determined by listening through the
abdomen for bowel sounds (the passage of gas). Bowel sounds indicate
that the normal movement inside the colon has returned. The passage of
stool is another indication that the colon is healing.
In some cases, a nasogastric tube is passed through the nose and into the
stomach during surgery and may remain for several days until bowel
function returns. After bowel function returns, clear liquids are given and
the nasogastric tube is removed. Once clear liquids are tolerated, the diet
slowly progresses to solid foods.
On the day after surgery, most patients get out of bed and walk around. It
is important to get up as soon as possible to stimulate bowel function and
help blood circulation return to normal.
The most difficult part of the postoperative period is adjusting to the
colostomy. The opening is on the right or left side, depending on where the
removed section of colon was located. The stoma is red and, immediately
after surgery, there may be a bandage covering it. When stool starts to
come out through the stoma, the colon is healing.
Stools from a stoma are generally softer and looser. The opening must
always be kept covered by a special pouch designed to hold the stool. The
pouch is changed after a bowel movement.
An enterostomal therapist teaches the patient how to care for the
colostomy and provide assistance with any problems that occur with an
ostomy. It is vital that patients and/or their family members learn proper
care of the colostomy before the patient is discharged from the hospital.
Hospitalization ranges from 3 to 10 days, and normal activity can usually
be resumed within 1 to 3 weeks. It takes longer for the body to heal
completely and strenuous exertion and heavy lifting must be avoided for 4
to 6 weeks.
Having a colostomy puts few restrictions on the patient, once initial
healing has occurred. There are usually no limitations on diet, sports,
activities, work, or travel. Sports that involve rough and frequent body
contact and jobs involving very heavy lifting are not advised.
Postoperative Complications
Complications that may occur with a colostomy are:
bleeding,
infection,
leakage around the stoma, and
injury to surrounding organs during the procedure.
If there is drainage, bleeding, or swelling at the incision site, pain that
is not relieved by medication and comfort measures, a sudden fever, or
rectal bleeding, the surgeon must be contacted immediately. If the
stoma is painful to the touch, draining blood, or swollen, infection or
other complications may be indicated.

INSERTION OF IV CATHETER AND DEBRIDEMENT
3. INSERTION OF INTRAVENOUS CATHETER
Etymology: L, intra, within, vena, vein; Gk, katheter, a thing inserted
a catheter that is inserted into a vein for supplying medications or nutrients
directly into the bloodstream or for diagnostic purposes such as studying
blood pressure.
POST OPERATIVE CARE
IV catheter and skin junction sites should be assessed for potential
complications (redness, tenderness, pus, warmth, and edema) at
established intervals by hospital policy.
The HCW should change gauze dressings routinely every 48 hours on
peripheral and central catheter sites and immediately if the integrity of the
dressing is compromised.
If gauze is used in combination with a transparent dressing, it is
considered a gauze dressing and should be changed every 48 hours.
If transparent semi-permeable dressings are used on peripheral IV sites
and as long as the integrity of the dressing is maintained, then the
dressing is changed at the same time as the 72-hour catheter site rotation
is done.
Tubing continuous primary and secondary administration sets should be
changed every 48 hours if there is an increase in the incidence of phlebitis
above recommended levels and/or if an increase in catheter-associated
infections is noted.
Primary intermittent or intermittent secondary tubing continues to be
changed every 24 hours.
Add-on devices, such as tubing extensions, filters, stop-cocks, and
needleless devices, should be changed when the administration sets are
changed.
4. DEBRIDEMENT
Debridement is the process of removing dead (necrotic) tissue or
foreign material from and around a wound to expose healthy tissue.
An open wound or ulcer can not be properly evaluated until the dead
tissue or foreign matter is removed. Wounds that contain necrotic and
ischemic (low oxygen content) tissue take longer to close and heal. This is
because necrotic tissue provides an ideal growth medium for bacteria,
especially for Bacteroides spp. and Clostridium perfringens that causes the
gas gangrene so feared in military medical practice. Though a wound may not
necessarily be infected, the bacteria can cause inflammation and strain the
body's ability to fight infection. Debridement is also used to treat pockets of
pus called abscesses. Abscesses can develop into a general infection that may
invade the bloodstream (sepsis) and lead to amputation and even death.
The four major debridement techniques are surgical, mechanical,
chemical, and autolytic.
Surgical debridement
Surgical debridement (also known as sharp debridement) uses a
scalpel, scissors, or other instrument to cut necrotic tissue from a wound. It is
the quickest and most efficient method of debridement. It is the preferred
method if there is rapidly developing inflammation of the body's connective
tissues (cellulitis) or a more generalized alized infection (sepsis) that has
entered the bloodstream. The physician starts by flushing the area with a
saline (salt water) solution, and then applies a topical anesthetic or antalgic
gel to the edges of the wound to minimize pain. Using forceps to grip the dead
tissue, the physician cuts it away bit by bit with a scalpel or scissors.
Sometimes it is necessary to leave some dead tissue behind rather than
disturb living tissue. The physician may repeat the process again at another
session.
PRE OPERATIVE CARE
assessing the need for debridement:
the nature of the necrotic or ischaemic tissue and the best
debridement procedure to follow
the risk of spreading infection and the use of antibiotics
the presence of underlying medical conditions causing the wound
the extent of ischaemia in the wound tissues
the location of the wound in the body
the type of pain management to be used during the procedure
Before surgical or mechanical debridement, the area may be flushed with
a saline solution, and an antalgic cream or injection may be applied. If the
antalgic cream is used, it is usually applied over the exposed area some 90
minutes before the procedure.
POST OPERATIVE CARE
After surgical debridement, the wound is usually packed with a dry
dressing for a day to control bleeding.
Afterward, moist dressings are applied to promote wound healing. Moist
dressings are also used after mechanical, chemical, and autolytic
debridement.
Many factors contribute to wound healing, which frequently can take
considerable time. Debridement may need to be repeated.
