Premature babies free essay sample

Premature babies are babies born before 37 weeks. For some babies they are born closer to their due dates and suffer from little to no consequences of being born born before their due date. Where as the term small-for-date refers to babies that are born at the desired due date, but are below the expected weight for the length of time spent in the womb. About 500,00 babies are born prematurely in the United States alone. Many premature babies are forced to spend extended times in hospitals and suffer from health problems that can affect later life. Premature infants need more intensive and immediate care than full term infants to help recovery and survival. Certain activities or health problems put a women at greater risk for having a preterm infant. Some women have no signs that they are going to deliver preterm. Some of the risks of having a preterm infant include multiple births and in vitro fertilization. We will write a custom essay sample on Premature babies or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Mothers carrying more than one baby have a greater risk of having a their babies born premature or small-to-date. Also women that do not get proper prenatal care put themselves at greater risk to have a preterm infant. Unfortunately, mom women cant afford the prenatal care necessary for the developing fetus or are not educated about behavior needed for a healthy pregnancy. They may not visit their doctor to help monitor the developing fetus and they may not being eating right. Some mothers develop eating disorders because they feel their bodies are changing and they think they are fat or unattractive. These women put their unborn baby in danger because they deprive the infant of the necessary nutrients needed for proper growth and development. Mothers that are overweight or underweight at conception also put their fetus at risk for being premature. Drug use, as in cigarettes and alcohol increase the risk of having a preterm baby, along with having a baby born with illnesses. Cigarettes use during pregnancy increases risks of asthma and difficulties breathing. The more cigarettes a mother smokes while pregnant, increases the risks, even if the the mother quits in her third trimester of pregnancy she could still reduce the risk of premature birth of her baby and health issues associated with smoking. Mothers who drink alcohol while pregnant increase the risks of premature births along with birth defects that are visible. Babies born to alcoholic parents suffer from Fetal Alcohol Syndrome (FAST) which has physical abnormalities and issues with memory, language and communication. Another factor that can increase risk for having a premature infant is illegal drug use. About 4% of expecting mothers in the United States use mood altering drugs , like cocaine and heroin. Babies born from drug using parents are greater at risk for premature birth, breathing difficulties, physical defects and death shortly after birth. The infants are born addicted to the substance the mother was using and become irritable and stressed when the drug supply from the mother is cut off. Drug use is linked to memory, language and motor development impairment is young childhood and academic issues. High blood pressure and diabetes also increase the risk of having a premature baby. Stress can also bring about a premature birth. For other women, they may have no signs of having a premature baby and dont engage in any risky behavior during pregnancy , and still deliver babies prematurely. Infants born prematurely need more care after birth to make sure they are able to survive and they have to be accessed for any abnormalities. After birth premature babies are immediately put in incubators to keep the babys NICE). In the NICE they receive specialized attention and monitoring to make sure the infant survives. Monitor systems are usually hooked up to babys chest to monitor breathing, heart rate, temperature. If the infant is having difficulty breathing, then the nurses in the NICE hook the baby up to a ventilator to help breathing stability. If the baby is weak and unable to breast feed or bottle feed, then IV fluid treatment is used to keep the baby hydrated along with feeding tube insertion. Feeding tubes go through the infants nose and the tube travels to stomach to ensure the nutrients are getting into the infant. Nurses, Doctors and staff in the NICE work around the clock to ensure that babies vitals are stable and the infant is surviving. Babies born premature and Jaundice are placed under blurring lights that help the infant break down excess blurring that builds up because the liver is not breaking in down. In some cases infants are given medications to help stabilize them. Liquid surfactants are spayed into the lungs to help under developed lungs develop. Antibiotics are given to infants that are at risk of infections or suffering from infections. Medications that increase urine production called diuretics are used to help the lungs and recirculation. Medications are also given to strengthen breathing and heart rate. Infants care is all specified to their particular illness and situation and the staff at the NICE work hard to be able to stabilize the babies for return to their mothers and family. Babies born prematurely require more hospitalizing and treatment then babies born normal term. Luckily advances in technology have increased survival in infants born prematurely. The longer the pregnancy, the greater the chance of survival is. The development of new technology and creation of NICE in hospitals allows for proper and better treatment of infants born prematurely. 0% of babies born at 28 weeks survive and more extreme cases or premature babies are surviving with the modern medicine advancements in hospitals. Being born premature can affect future mental, developmental, and behavior problems that affect early childhood or become permanent. Doctors have no way of determining how prematurely will affect later development and growth. Premature babies can suffer from health issues upon arrival into the world. Some premature infants develop Apneas. Apneas causes delayed breathing for 20 seconds or more and can also affect heart rate by decreasing it dramatically. Babies with Apneas re closely monitored and hooked up to breathing and monitoring devices to keep track of the infants breathing. Infants born prior to 34 weeks usually do not have fully developed lungs which makes them have Respiratory distress syndrome (RODS). In RODS the baby cannot breath properly because they do not have a specific protein called surfactant. Surfactant is a protein that keeps small air sacs in the lungs from collapsing. Infants with RODS are immediately rushed to NICE and treated. Another lung issue can be precautionary dysphasia (BAD) which is when babies have damage or fluid in their lungs. Another health problem is Intracellular hemorrhage (IV). This is when the infants brain has internal bleeding which normally occurs near the ventricles near the center of the brain. Ventricles are spaces in the brain that are filled with fluid. These babies also need immediate emergency care. Some premature babies suffer from heart issues like Patent ducts arterioles (PDA). This closed properly causing breathing problems and even heart failure. Intestinal issues are sometimes also prevalent such as Engineering interconnections (NECK). This health problem causes a swollen belly and diarrhea and can appear 2 to 3 weeks after birth. Some infants are born anemic and do not have healthy red blood cells to carry oxygen to the body. Treatment sometimes involves blood transfusions. Other premature infants are born with Jaundice which is when the liver does not function properly and babies are yellow in appearance. Babies are put in the blurring light incubators to help control and treat the issue. Premature babies can also be born with multiple infections such as pneumonia, meningitis and sepsis. Premature babies require more attention then full term healthy babies. Infants born premature are also subject to issues later on in life. Studies show that babies born prematurely are more likely to get lower test scores in math and reading, than babies born full term. A study published in 2011 analyzed long term effects of cognitive abilities such as memory and attention span. In the study the researchers concluded that babies born extremely premature did worse on function test and took more time to complete IQ tests. Also adults that took IQ test scored an average of 8. 4 points lowers than adults born full term. Another study conducted that babies born between 22 and 25 weeks where at risk for developing neurological impairments around 4 to 8 years old. In 2012 researchers from the University College London Institute for Womens health reported that even with advances in technology, the long term of effects of being born prematurely have not changed in the past decades. Advances in technology have increased survival rate in in infants born prematurely, but have not been able to change the issues with cognitive functions and higher risk for particular disorders. Infants born prematurely are more Likely to have weaker immune systems and develop respiratory issues, like asthma. This can e costly for the parents and in some cases lead to early death. Increases in NICE staff and technology have helped the premature babies and decrease many issues that used to be fatal. Unfortunately some issues still arise in later life due to lack of cognitive and physical development at birth. Premature babies need more care than full term babies because they are still fragile and some are barley ready for survival outside of the womb. Premature births occur every day and steps can be taking to decrease the risks, but even with proper prenatal care delivering preterm still can occur. Premature babies need excessive immediate care to help increase survival and decrease disabilities and disadvantages of being born preterm. Premature infants are born under developed and need intensive care to help make sure they are able to develop outside of the womb and survive with the ability to normally function. Doctors and nurses of the NICE work around the clock to help infants born preterm stabilize and to prepare them for transition in to the real world. Parents and family all eagerly wait for their infants to be able to go home. Preterm infants need more care than full ERM infants immediately following deliver due to the fact that preterm infants should still be developing in the womb.

Identifying the Most Common North American Conifers

Identifying the Most Common North American Conifers Conifers are commonly thought to be synonymous with evergreen trees, which stay green through the year. However, not all conifers- also known as softwoods- remain green and with needles year-round. They are actually scientifically classed by how they fruit. They are gymnosperms or plants with naked seeds not enclosed in an ovary; these seed fruits called cones are considered more primitive than hardwood fruiting parts. General Guidelines for Broad Identification Though conifers may or may not lose their needles annually, most are indeed evergreen. Trees of this classification have needle-like or scale-like foliage and usually renew many leaves annually but  dont renew all of their leaves every year. The foliage is usually narrow and manifests in either sharp-pointed needles or small and scale-like leaves. Although  studying the needle is the best way to identify a conifer, conifers as a class are defined not by their leaves but by their seeds, so its only important to note the shape and size of leaves after determining whether it is a conifer by the shape, size, and type of seed the tree produces. Softwood trees  include pine, spruces, firs, and cedars, but dont let that alternative name for conifers fool you. Wood hardness varies among the conifer species, and some softwoods are actually harder than some hardwoods. The Many Types of Coniferous Leaves While all trees that bear cones are coniferous, and many of these cones are remarkably different from other species cones, often times the best way to identify the specific genus of a tree is by observing its leaves. Coniferous trees can produce two types of leaves with a variety of slight alterations that further define the tree type. If a tree has needle-like (as opposed to scale-like) leaves, it can then be further defined by how those needles are grouped (singularly or alone), how they are shaped (flattened or four-sided and sharp), the types of stems these leaves are attached to (brown or green), and if the leaves invert or not. Other Ways to Identify Conifers From there, the way the cone or seed is shaped and the way it hangs on the tree (sticking up or handing down), the smell and largeness of individual needles, and the erectness of branches in the tree can also help determine what specific type of conifer a tree is. Chances are ​if a tree has any of these features at all it is a conifer, especially if the tree also bears cone-like seeds. The Most Common Conifer Trees in North America Three of the most common conifers that grow in North America are pine, fir, and spruce trees. The Latin word conifer means to bear cones, and most but not all conifers have cones; junipers and yews, though, produce berry-like fruit. Conifers are among the smallest, largest, and oldest living woody plants known in the world. The more than 500 conifer species are distributed worldwide and are invaluable for their timber but also adapt well to the landscape; there are 200 conifer species in North America, but the most common are listed here: Bald cypress- Genus  TaxodiumCedar- Genus CedrusDouglas fir- Genus  PseudotsugaTrue fir- Genus AbiesHemlock- Genus TsugaLarch- Genus LarixPine- Genus  PinusRedwood- Genus SequoiaSpruce- Genus Picea
