One World Essay: Premature Babies

Vikram V.

Premature birth is the term used to describe the birth of an infant prior to the completion of it’s prenatal development and normal gestation; in humans, this is typically considered to be between the 20th and 37th weeks of pregnancy, before which it is referred to as a miscarriage. Labour is a complex process, involving a number of factors, and as such, it’s often difficult to determine the cause of prenatal birth. Despite this, there are a number of reasons that could be attributed to such, both within individuals as well as populations. One of such causes exists within multiple pregnancies; the birth of twins, triplets, quadruplets, etc. Twins have been found to be up to five times as likely to be born prenatally then those born in a single pregnancy (Gardner, Goldenberg, Cliver, Tucker, Nelson & Copper, 1995), with triplets being even more vulnerable to premature birth. Alternative factors exist in the medical condition of the mother - both anatomically and otherwise. The mother may have a weak or short cervix, or have a uterine malfunction, leaving her uterus unable to hold the growing foetus, as it has a limited capacity. These are considered to be the strongest predictors of preterm birth. Other medical reasons, such as high blood pressure, and asthma may also be considered causes. The usage of drugs, excessive alcohol and smoking by the mother in the duration of the pregnancy are considered as environmental factors attributed to premature birth. Certain infections, such as bacterial vagenosis, if spread can and have also resulted in an increased level of preterm birth throughout a population, they affect the inflammatory response which leads to preterm birth and are easily spread. Other similar infections include: pyelonephritis, asymptomatic bacteriuria, pneumonia and appendicitis. The problems that arise from preterm birth are usually dependent on the degree of foetal development the infant has developed into at the stage of the birth. An average human’s gestation period is nine months, or 38 weeks. The table below (following page) shows the effects of preterm birth at different stages of pregnancy, as well as the development of the foetus. Preterm babies are at greater risk of serious health problems such as celebral palsy, chronic lung disease, vision or hearing loss, and are also more susceptible to developing depression as teenagers (Dunn, 2004).

- Neck has begun to take shape. - Body muscles partially developed. - Begins wriggling. - The mouth cavity and nose are adjoined.

Miscarriage

- Baby flexes and kicks. - Bone begins to replace cartilage. - Hormones ‘start up’. - Facial expressions are made possible. - Fingernails and Toenails are present.

Miscarriage

- Heart visible in an ultrasound. - Genitalia recognizable. - Scalp hair sprouted and continues to develop.

Miscarriage

- Sense of balance develops. - Can successfully ‘suck’. - Eyebrows are visible.

Low chance of survival (20%). possibility of brain hemorrhaging. Drugs may be used to accelerate the development of lungs.

- Eyes can open: blink, open and close.

50/50 chance of survival outside of human body. Lungs have been further developed. Would definitely require support, eg: Incubator. Considered the limit of viability.

- Eyes completely opened - can detect light. - Lungs and Digestive Tract are mature.

35

- Reflexes are coordinated. - Body is growing round due too developing fat layers.

Excellent chance of survival if born outside of womb (60%).

90% chance of survival. Little or no effects - a regular birth. 2

Hospitals deal with preterm birth in a number of ways, and is largely dependent on the time at which the mother gives birth. In most modern hospitals, there are special facilities existing for the purpose of treating preterm infants. These are commonly known as Neonatal Intensive Care Units (NICU). In NICUs preterm babies are generally kept in incubators (left), which serve as imitations of the placenta providing the baby with the resources it requires to fully develop within the ideal temperature. At earlier stages of pregnancy, certain organs, such as the lungs (the last organs to develop in pregnancy) may not be fully developed, and as such special medication to accelerate their growth, as well as a ventilator. Despite this, not all complications arising from premature birth can be resolved with science. Certain complications stemming from preterm birth, such as brain hemorrhaging, are considered to be incurable and can result in death. such is a limitation of science. A controversial issue surrounding preterm birth exists in abortion. Abortion is the term used to describe the termination of pregnancy through the removal of the foetus or embryo, resulting in it’s death. This is considered by some to be a solution to those births in which either the mother will be seriously crippled by the birth, or the baby will have a lower standard of living as a consequence of itself being born. This has caused much ethical debate, as some consider it a form of murder - the purposeful killing of another human. However, others debate, as the child is still in an embryonic or foetal state, that it does not yet constitute a human, and cannot feel the pain of it’s death. Personally I feel that this is largely dependent on the stage to at which the baby has developed to before abortion is considered. At which stage does the foetus begin to feel pain and consequently the abortion? I am however firm in my belief that, were the child guaranteed to either die or have crippling malformations at birth, then abortion would be a positive alternative to such. This however raises another related debate. Should doctors consider infants born with congenital defects for treatment? How should resources be allocated towards such? Should taxpayer’s money be spent on those who are born defected? I believe that those in such conditions should not be allocated healthcare over other patients, but at the same time they should not be demote below them. They have just as equal rights to healthcare as any other human, and, regardless of defection, should be treated as such. Others argue that they are in such a state in consequence of the will of god, and such should not be contested. However, I consider thus perspective less considerable, as their is no evidence to support it. The area of interaction I find this essay to be most related to is health and social education. It explores the importance of sustaining personal well being within a physical and social environment, complications arising through the mistreatment of such (such as in alcoholism and smoking), as well as solutions and consequences. 997 words.
