 I. Introduction

Narcotic analgesics, especially morphine are underused for pain control with in the medical field. This underuse is because medical professionals, including doctors, fear patient addiction, side effects and possible lose of their licenses. These fears deny adequate healing and a better quality of life to those who would benefit from a more effective use of these drugs, as done in hospice care.



 II. PAIN:

Pain not only involves the physical reaction to damaged tissue, but also involves an emotional and cognitive response by the person experiencing the pain (Backer, 1994). A person's prior experience will influence how pain is managed. Pain is a signal that something is not quite right, and is one of the main reasons a person will seek out the attention of a doctor. Pain is also elusive. "It can't be seen or imagined, and measuring pain remains a subjective process," (Kohler, 1992). Although pain is elusive and subjective, it is still very real. Pain hurts. If left untreated, or inadequately treated, pain can overwhelm and consume a person's life. Instead of being a signal to a problem, pain becomes the problem.

Various factors influence the pain a person feels when injured, sick or recovering from surgery. Different people have different thresholds of pain. A headache that sends one person to the medicine cabinet for aspirin may not bother another person. "Nonphysical factors, such as fear, anxiety, depression, and fatigue," (Backer, 1994) are also variables which influence reactions to the threshold pain. If an adolescent complains of a headache, and the parents' ask if she took something for it, she will more than likely take pain medication before complaining next time. Cultural values also play a part in pain response. Our culture admires "Stoicism and tolerance," (Backer, 1994). Pain is not inevitable and can be treated. To live a life hampered by pain when treatment is available, is to cheat one out of the full quality of life that is possible.

Pain effects the body through the nerves. The phenomena of pain is conveyed from a peripheral part of the person, through afferent nerves to a part of the brain, similar to sight, touch, and hearing. These signals are then interpreted by the brain as pain (Murphy, 1981). The nerve cells used to relay pain messages to the brain are specific nerve cells called nociceptors. These nerves do not send messages until "the stimulus reaches noxious levels," (McClesky, 1992).

Pain can be acute or chronic. Acute pain is intense, short in duration and generally a reaction to trauma. Chronic pain does not go away, and can range from a dull ache to excruciating agony. Terminal and non-terminal illnesses can both be causes of chronic pain. Tissue damage is not always found in chronic pain, but those who suffer from it are rendered "nonfunctional by incapacitating pain," (Murphy, 1981).

 Chronic Pain

Chronic pain has four mechanisms. Nociception is a neural signal of threatened or damaged tissue, and is the classical pain pathway. Central pain states are thought to be caused by abnormal activity in neurons in the afferent pathway. The mechanism for this is not completely understood, and a person may perceive pain where there is no tissue damage. Behavioral pain is communicated by a word, grimacing, posturing, and other behavioral signals. These signals indicate that a person is in pain, (Murphy, 1981).

A person suffering from chronic pain may undergo a change in personality becoming irritable and moody. The pain is responsible for this change in a formerly good natured person. Pain is emotionally and physically, draining. These dual effects not only take a toll on the ill person but also on her, family and friends. The person with the pain deals not only with the agonizing pain, but also with the guilt and frustration of not being the person she was before the pain.

 Post-Operative

Post surgical pain is an acute pain rather than a chronic pain. It is due directly to the fact that an incision was made, creating tissue damage. Depending on the surgery, the pain can diminish quickly within a day or two. However recovery can take a bit longer, and postoperative pain is very common in the recovery room.

The severity and reason for this pain has many factors. Age is important. The two extremes of very young and very old, seem to have lower instances and less pain than those patients in the middle of life. Fear of pain and some neuroses also seem to increase the postoperative pain. Preoperative medication can affect postoperative pain. Barbiturates and some other medications seem to worsen post-Op pain. Narcotics on the other hand delay the need for a painkiller in the recovery room. The site of the incision and procedure also have a significant influence on post-Op pain. A surgery in the thoracic region seems to be the most painful type of operation, and lower abdominal surgery the least painful. The technique of the anesthetic, such as the presurgical use of narcotic analgesics is important, but not the type of anesthetic (Murphy,1981).



 III. OPIATES:

Chronic pain and post-surgical pain can both be alleviated by the use of opiates. Opiates are a type of drug extracted from the pod of the Asian poppy. These drugs have been used medically and non-medically for centuries. Laudanum has been used since the 16TH century to stop coughing and diarrhea, and to calm nerves. In the 19TH century morphine was extracted in its pure form and became an injectable solution with the use of the hypodermic needle. In 1898, heroin was introduced. At first heroin was thought to be a remedy for morphine addiction. It turned out to be not only a more potent pain killer, but also much more addictive than morphine. Heroin is the only opiate more liable to create dependence than morphine. Only two natural opium products are still used today for clinical use, morphine and codeine. The synthetic opium products are generally called opioids. These drugs were developed to produce the same type of analgesic uses, but with out the drug dependence (Addiction Research Foundation,1995).

 Morphine

Morphine is a strong narcotic analgesic used in the management of moderately sever to severe pain.. It is not a very popular street drug, but its availability in the hospital has created some abuses by health professionals. Morphine can also relieve certain types of difficult breathing, suppress coughs, and cholera produced diarrhea. Its typical dosage is between 5-20 mg every four hours for an intramuscular injection and 8-20 mg orally. If used intravenously it is usually 4-10 mg used for postoperative pain. The intravenous effect is almost immediate.

Codine

Codeine is the other natural opiate used in the medical field, and like heroin, it synthesized from morphine. This opiate is used more for mild to moderate pain, rather than sever pain, and is typically combined with Tylenol. This combination is sold as Tylenol #3 w/ codeine and provides relief from a cough and diarrhea, similar to morphine.

 Other Derivatives

Hydrocodon, hydromorphone, meperidine (Demoral), and Oxycodone (Percodan) are all semi-synthetic opioids used in the medical field. These medications are also used as narcotic analgesics and have some dependency potential. The effects of all of these last three to four hours and are used for moderate to severe pain,.

Synthetic opioids are Fentanyl, methadone, propoxyphene, and pentazocine. Fentanyl is used for moderate pain relief and as a surgical anesthetic. The effects of these medications last one to two hours. Propoxyphene is used as a mild pain reliever, and methadone is used mostly in the treatment of opioid withdrawal (Mdh@debug.cuc.ab.ca,1994).

 Side Effects

Dependence is a side affect common to all opiates, natural and synthetic alike. Opiates have specific withdrawal and dependence characteristics, Prolonged use causes both psychological and physical dependence. Chronic opioid users may also develop endocarditis, an infection in the lining of the heart. Drug users may use contaminated needles, increasing their risk for AIDS and other diseases which are transmitted through the sharing of unclean hypodermic needles (Mdh@debug.cuc.ab.ca,1994). The withdrawal from opioids is not a painless event, but neither is it life threatening. Withdrawal symptoms include uneasiness, yawning, tears, diarrhea, abdominal cramps, goose bumps, runny nose, and a craving for the drug (Addiction Research Foundation,1995).

A slightly reduced respiratory rate is one of the side effects for the medical use of morphine, and other opiates. This side effect worries some doctors of cancer patients, because as the cancer metastasizes the pain becomes worse and therefore a higher dosage of morphine is needed. The higher dosage may ultimately reduce respiratory rate to the point where a person is not breathing, although this is not as common as it may sound at times. Other side effects are constipation, nausea, loss of appetite and decreased gastric motility (Mdh@debug.cuc.ab.ca,1994).


 IV. PAIN CONTROL:

 Hospice Care

Hospice is probably the best example of effective pain control using morphine, and other opiates. The concept of hospice has its roots in Christianity. In the beginning of Christianity, places for the care of the sick, poor and dying were called Hospitia and were run by religious orders. Current hospice care also stems out of a history of religious affiliation. The Irish Sisters of Charity founded Our Lady's Hospice in Dublin in the 1800s, and St. Joseph's hospice for the dying poor in England was founded in 1902 (Backer, 1994).

Just as Jesus showed care and compassion for those in pain, sick and dying, those people who founded Hospice clinics and charity hospitals had strong Christian beliefs, gifts of healing, and felt the need to do the same. Today's Christian health care workers should feel a similar need to ease the pain and suffering. A physician cannot use the same techniques that Jesus used to help those in need. It would be impossible. It is with the gifts God has given that a physician may help those in need. Medicine, including morphine, is one of those gifts.

 Chronic Pain Control

" It is scandalous that in almost every case suffering was largely preventable and unnecessary, inflicted not by the disease, but by shocking medical ignorance, arrogance, complacency and pride," (Dixon,1997). Dr. Ilora Finlay gives a six step guide to obtaining adequate pain relief.

Backer gives a list of "Ten Commandments" for the health care profession which is appropriate to the problem of inadequate pain control.

1. Thou shalt not assume that
the patient's pain is caused by the malignant process.
2. Thou shalt take into consideration the patient's feelings.
3. Thou shalt not use the abbreviation p.r.n. (meaning as needed).
Continuous pain requires regular preventative pain management.
4. Thou shalt not prescribe inadequate amounts of any analgesic.
5. Thou shalt try nonnarcotic analgesics in the first instances.
6. Thou shalt not be afraid of narcotic analgesics.
7. Thou shalt not limit thy approach simply to the use of analgesics.
8. Thou shalt not be afraid to ask a colleague's advice.
9. Thou shalt provide support for the whole family.
10. Thou shalt have an air of quiet confidence and cautious optimism.

Although these commandments were used in reference to hospice, many other medical areas can benefit from these ideas. Health care providers, especially Christian ones, have an obligation to provide the best care possible to their patients,. The duty to follow Jesus by giving comfort and compassion is inherent in the profession chosen by the Christian. This does not just mean to give of your time, but also of you talents and knowledge. Health care providers need to educate themselves on the benefits of more effective morphine use in the treatment of chronic pain, for both terminally ill and the nontermially ill.


 V. CONCLUSION:

The gift of healing is important and should be used to help others. The duty of a Christian health care worker, be it the position of nurse, physician, pharmacist, or other, is to not only use their own personal gift, but to enhance it through education, and a thorough search for the best possible treatment. In the case of chronic pain, morphine works better and with fewer side effects than most drugs (Herrera, 1997). Not only does morphine relieve pain, it also helps prevent pain (Gorman, 1997). Morphine should not be given indiscrimanently. A doctor prescribing any opiate should be aware of any and all side effects, and explain them to the patient and family.

Pain is a common human experience. Dying is also a common human experience. For those who have a terminal illness, dying in pain does not need to be experienced. Doctors need to be educated on how to properly use narcotic analgesics for the terminally ill. They also need to be allowed access to adequate use of narcotic analgesics, especially morphine, for those with chronic pain who are not chronically ill. Once the physical pain is alleviated, emotional pain and negative coping mechanisms may be address through a collaborative effort of different health care workers.

People trust their doctors and nurses to do what is best for them. It is a violation of trust, and a misuse of a God-given gift to not find the best available method and use it to help the patient. If the best option is not available because of societal fears, such as morphine, The doctor, and other health care workers should become advocates to help obtain access to the treatment. A health care worker should follow the example of Jesus when caring for those in pain. He took away the physical pain first, knowing that the person would then be able to focus on faith.
