Postoperative
Pain Management
Postoperative
pain management actually begins preoperatively. Your anesthesiologist
and surgeon will decide on a plan prior to your surgery. A major deciding
factor with regard to choosing an appropriate plan will depend on whether
the patient is to be discharged the same day (day surgery) or will be
admitted after surgery.
The
following techniques may be used to treat postoperative pain.
PCA (Patient Controlled Analgesia)
This device allows patients to control their own pain relief immediately.
Using a push button connected to a small programmable pump, a patient
causes the release of pain medicine into his/her intravenous (IV). Within
2-5 minutes, the patient will experience relief. The pump can also be
programmed to provide a continuous infusion of pain medicine as well
(this may actually reduce the number of pushes on the button).
Is
it safe? Most studies show patients actually use less medication
compared to having a nurse deliver the injection. Because the patient
can treat pain as it starts to increase, the pain should never get out
of control. Significant delays can occur if the patient has to call
the nurse, explain that he/she is in pain, and have the nurse retrieve
and then administer the pain medication. The longer the delay, the more
pain increases and therefore more pain medicine may be required. PCA
avoids this delay.

Epidural
Analgesia
An epidural involves the continuous delivery of pain-relieving medication
to nerves within the epidural space of the spinal column. Preoperatively,
a small catheter is placed and secured to the patient's back.
The catheter is then connected to a small programmable pump that delivers
continuous pain medication.
The
advantages to epidural analgesia are: less sedation, improved pain relief,
decreased risk of blood clots (in some patients), and decreased risk
of ileus (slowing down of the stomach and intestines). Disadvantages
are headache (risk less than 1 in 200) and numbness of the lower extremities
(not common).

PCEA
This option is planned initially for obstetrical patients and should
be available for postoperative pain relief by 2004.
PCEA,
or Patient Controlled Epidural Anesthesia, combines the PCA and Epidural
Analgesia techniques. After the epidural is placed, the catheter is
connected to a programmable pump that delivers a continuous infusion
of pain relieving medication and allows the patient to self-administer
extra medication (a “bolus”).

Walking
Epidural
A walking epidural is an epidural that is used for pain relief. It is
often used to describe an epidural for laboring mothers. At SSH, laboring
patients are not allowed to walk once an epidural is placed. In fact,
at most centers where a "walking epidural" is promoted, patients
are discouraged from walking or are not permitted to do so. The reasons
for this are numerous.
Walking
epidurals are used at SSH following surgical procedures. In most cases,
the epidural infusion affects the surgical site and not the legs. These
patients are encouraged to walk as it speeds the recovery process.

Pain
Buster
The PainBuster® (dj Orthopedics, LLC) is a system that provides
continuous infusion of a local anesthetic directly into the surgical
wound. The main advantage to this system is that it can be used in outpatient
surgery.
It
is generally used for orthopedic procedures and is placed during the
operation by the surgeon. It is designed to last approximately 48 hours
and can effectively alleviate the moderate to severe pain a patient
may experience following many surgical procedures.

Nerve Blocks
Nerve blocks are used to provide regional anesthesia. In regional analgesia,
only a specific area of the body is targeted for pain relief. Each particular
nerve block affects a specific area of the body. A nerve block is performed
before surgery using a needle to inject local anesthetic around a particular
nerve or group of nerves. The result is the affected area is anesthetized.
Nerve
blocks are used primarily for postoperative pain relief, but can also
be used for surgery. The nerve block therefore may be used in combination
with a general anesthetic or sedation. This decision is made preoperatively
by the anesthesiologist, surgeon, and patient.
The
following are examples of nerve blocks performed by SSAA:
- ANKLE
(anesthetizes the foot)
- AXILLARY
(anesthetizes the arm and hand)
- CERVICAL
PLEXUS (anesthetizes the neck)
- FEMORAL
(anesthetizes the thigh and part of the knee)
- INTERSCALENE
(anesthetizes the shoulder, arm, and hand)
- POPLITEAL
(anesthetizes the lower leg and foot)
- SCIATIC
(anesthetizes the thigh, lower leg, and foot)
