Premature neonates or preterm babies refer to the neonates that are born before 37 weeks of gestation are over. Given that most of the body organs are not completely developed at this stage, the neonates have a high risk of developing many complications at birth. A good example of these organs is the lungs, which completely mature by week 36 of gestation. Therefore, neonates born at 37th weeks are likely to have immature lungs that are associated with respiratory problems such as respiratory distress syndrome, pneumonia, and apnea of prematurity. Respiratory distress syndrome (RDS) develops as a consequence of the lung’s inability to produce enough surfactant necessary for maintaining the air spaces in the lungs in an open state.

According to DiBlasi, even in animal models, the conventional methods cause inflammation of the lungs and sometimes cause injure to the lungs.1 These techniques also cause redundancy in alveolar growth and also affect the efficacy of surfactant produced in the animal lung.1 This is a good signal that these techniques may have serious consequences in the neonate. One of the adverse effects of invasive and mechanical ventilation is ventilator-induced lung injury.1 This complication is defined by the presence of polytrauma (excessive tidal volume) and shear injury to the airways, a condition known as atelectrauma.1 Insertion of the endotracheal tube into the lungs through the airways also causes injury to the lungs and the airways, a condition known as endotrauma.1
Insertion of the endotracheal tube through the airways is also a painful procedure that may need the neonate to be sedated first. According to DiBlasi, insertion of the tube may also cause acute airway injury, emergencies, an infestation of the airway with bacteria, reduced ciliary function and increased resistance to airflow that may result to increased work of breathing (WOB) energy required for breathing.1 Another common complication associated with a conventional method is bronchopulmonary dysplasia.2 This is usually a serious condition, and may progress to a condition that resembles chronic asthma later in the child’s life.2 According
It has been repeatedly stated that oral care is important in the prevention of ventilator-associated pneumonia (VAP). Endotracheal intubation predisposes patients to developing VAP. The tube acts as a conduit from the mouth to the lungs – a perfect track for bacteria to descend upon. Khezeri, et al. (2014) suggest that “the presence of an endotracheal tube (ETT) inhibits normal coughing, normal swallowing, and the protection of the trachea contact by epiglottis closure.” In addition, an endotracheal tube keeps the patients mouth open – leading to dryness. Bacteria are not washed away by saliva. Also, Landgraf, et al. (2017) mention that the presence of an endotracheal tube in the mouth causes “changes in the oral epithelium” which “might indicate risk for infection in intensive care patients
According to the World Health Organization (WHO, 2016), preterm birth are the birth that happened before 37 ended weeks of pregnancy and is one of the number reason of newborn deaths and the second prominent cause of deaths in children below five. The preterm babies have chances of an amplified risk of illness, disability and death. In the first weeks, the complications of premature birth may include: breathing problems, heart problems, brain problems, temperature control problems, gastrointestinal problems, blood problems, metabolism problems, immune system problems. Long-term complications includes cerebral palsy, impaired cognitive skills, vision problem, hearing problems, dental problems, behavioral and psychological problems, chronic health issues.
Neonatal RDS is a condition of increasing respiratory distress commencing at or shortly after birth (BAPM-2006). It’s the single most important cause of morbidity and mortality in preterm infants (Greenough, et al 2004). Typically RDS affects preterm infants with the incidence being inversely proportional to the gestational age (Stewart 2005) Approximately 60% of those born before 28 weeks gestation are affected (Fraser, et al 2004) Incidence also increases in infants of diabetic mothers those born via elective caesarean section (Fraser, et al 2004) and perinatal asphyxia (Rodriguez, 2003).
Air escaped from the lung into the pleural space. Eventually, enough air collected in the pleural space to cause the mediastinum to shift twoard the right. The collapsed left lung, increased intrapleural pressure, and rightward shift make it difficult to ventilate A.W.
Although when it happens, there can be a devastating impact on patients as well as to the multidisciplinary theatre team involved. Consequently, the DAS has produced a consensus set of guidelines for managing failed intubations in adult and paediatric patients, but there are as yet no such nationally-agreed guidelines in obstetrics, therefore each obstetric unit should have their own flowchart with regards to management of failed intubation (Brien and Conlon, 2013). Furthermore, in light of the latest DAS guidelines, several aspects of clinical anaesthetic practise have changed over recent years (Frerk at al, 2015). Amongst the changes are the use of new drugs such as rocuronium and suggamadex and using electronic video-laryngoscopes (Frerk et al, 2015). Further work had also looked at extending the period of apnoea without causing desaturation by optimising the preoxygenation process and adequate patient positioning (Frerk et al, 2015). As a result, updated guidelines for difficult intubations in adult patients were published in 2015; these guidelines provide a flowchart to be used when endotracheal intubation proves difficult or impossible and focus on the central importance of oxygenation while reducing the amount of airway interventions in order to minimize trauma to the delicate airway (Frerk et al, 2015). The main message of the revised guidelines is
Premature birth has been linked to a vast array of lungs problems, the earlier the birth the greater risk of health complications(Davis R and Mychaliska G, 2013). A majority of the health problems will affect the infant for the rest of their life (Davis R and Mychaliska G, 2013). Infants born between the canalicular and the saccular period (week 25) have lung development that is unsuitable for gas exchange (Davis R and Mychaliska G, 2013). Two major complications that arise with undeveloped lungs is bronchopulmonary dysplasia, and pulmonary arterial hypertension (Mahgoub L. et al. 2017).
his neurologic intensive care unit (NICU) stay, Y.W. was intubated and placed on mechanical ventilation, had a feeding tube inserted and was placed on tube feedings, had a Foley catheter to down drain (DD), and had multiple IVs inserted. He developed pneumonia 1 month after admission.
Endotracheal tubes containing a tapered cuff have recently been approved by the United States Food and Drug Administration and, based on the findings from in vitro and in vivo studies, are believed to achieve a better tracheal seal (Bowton et al., 2013). This enhanced fit is suggested to reduce the passage of potentially contaminated secretions around the cuff and into the distal airway of mechanically ventilated patients, thereby decreasing the development of VAP. In a study executed by Bowton et al. (2013), researchers examined whether these tapered endotracheal tubes would be more effective in reducing actual rates of VAP. Their study utilized a two-period observational approach in which each study period took place over six of the same calendar months so as to eliminate potential variations in season related to VAP. All adults over the age of 18 who were admitted into a variety of specialized ICUs, whose VAP rates closely resembled the average of all ICUs in the United States, were included in the study. During the first six month period, all endotracheal tubes utilized by the facility contained the standard, barrel-shaped cuff. Following this period, an audit was performed to ensure that all of these tubes were removed and, subsequently, they were replaced with tapered-cuff endotracheal tubes. Additionally, all emergency medical
Another group of patients which require challenging ventilation strategies are the preterm infants. The lungs of preterm infants have undeveloped distal airway structures, with a thick air/blood barrier and a small surface area for gas-exchange (Wallace et al., 2009). They are most likely to be surfactant deficient due to under-developed epithelial cells which lack the type II alveolar cells (Wallace et al., 2009). As a result, preterm infants often require respiratory support in the minutes following birth (Roupie et al., 1995).
Postnatal respiratory complications among newborns are common. The most commonly reported cause of neonatal respiratory distress is transient tachypnea of the newborn (TTN), with an estimated incidence of 1% to 2% of in all newborns.1
As a father who has personally experienced the struggles and hardships of having a premature child, I feel like giving you information on this subject is a lot easier for me to share than most things. I will preface by sharing my son 's experience; he was born at 26 weeks gestation, weighing 2 pounds, 6 ounces, and spent more than three months in the Neonatal Intensive Care Unit (NICU) that was available in Columbus, Georgia. A large amount of families with infants in the NICU asks what the outlook for babies born earlier than 28 weeks might be? Less than 1 percent of babies in this country are born this early (earlier than 28 weeks), but these babies have the most complications despite great technological advances in medicine today. Premature children born at an extremely low birth weight (less than 2 pounds, 3 ounces) almost always require treatment with oxygen, surfactant, and mechanical assistance to help them breathe (even if for a short period of time until they can breathe on their own without assistance). These babies are too immature to suck, swallow, and breathe at the same time, so they must be fed through a vein (intravenously) until they develop these skills to do so. They often can not cry (or you can 't hear them due to the tube in their throat causing a kitten-like groan), and sleep most of the day to allow for growth and development outside of being in the womb. These tiny babies have little muscle tone,
Necrosis of the cells in the small, lower airways occurs, and mucous secretions are increased (Conquest, Cremonesini, & Neill, 2013). Because of the ciliary damage in the infants’ lungs, it is almost impossible for the secretions to be cleared. Bronchiolar level obstruction is caused by these mucosusal secretions, as is desquamation of the dead skin cells and edema (Conquest, Cremonesini, & Neill, 2013). Plugs of soughed, necrotic epithelium and fibrin in the airways will cause partial or total obstruction to airflow, making it very difficult for he infant to exhale which will consequently result in air becoming trapped and will reduce gaseous exchange (Conquest, Cremonesini, & Neill, 2013).
In 1974 Ward reported an incidence of 3% of symptomatic pneumothorax after ISB by paraesthesia blind technique. The pneumothorax was almost certainly produced by the prior attempt to carry out a supraclavicular block, as it is difficult to imagine the apex of the lung reaching as high as C6, the level of an
Pregnancy is normally the best and the happiest stage of any woman, but it can also be uncertain because anything can go wrong if you do not know exactly what to do. In order to understand the reasons of why Preterm Birth occurs, it is important to know what it is and how risky it can be. Preterm Birth is also known as Premature labor which mainly begins after “20 weeks but before 37 completed week’s gestations. Approximately 12.9 million babies worldwide are born too early every year representing an incidence of PTB of 9.6%” (Berghella, pp. 2, 8). Baby Center Medical Advisory Board says that about 12 percent of babies
Respiratory distress syndrome (RDS) is a common lung disorder that mostly affects preterm infants. RDS is caused by insufficient surfactant production and structural immaturity of the lungs leading to alveolar collapse. Clinically, RDS presents soon after birth with tachypnea, nasal flaring, grunting, retractions, hypercapnia, and/or an oxygen need. The usual course is clinical worsening followed by recovery in 3 to 5 days as adequate surfactant production occurs. Research in the prevention and treatment of this disease has led to major improvements in the care of preterm infants with RDS and increased survival. However, RDS remains an important cause of morbidity and mortality especially in the most preterm infants. This chapter reviews the most current evidence-based management of RDS, including prevention, delivery room stabilization, respiratory management, and supportive care.
