Parents frequently demonstrate reactions of acute grief 97110 treatment code buy 3 mg exelon otc, such as somatic disturbances medications you can take while pregnant for cold exelon 4.5mg cheap, a preoccupation with the newborn’s appearance or probable future appearance medications without doctors prescription cheap exelon 4.5mg fast delivery, guilt, hostility, and loss of ability to func tion. These materials can be designed by the individual hospital or obtained through various associations. Neonatal Complications and Management of High-Risk Infants 369 Because families may come from a distance and may not be well acquainted with the attending physicians, it is especially important that referral centers that provide neonatal care designate a member of the team to be an advocate for the family during the hospital stay and after discharge. The designated individual also should be responsible for documenting the management and follow-up of each death. Too often families are lost to follow-up when physicians, nurses, and families avoid sharing the sadness of bereavement. This process is helpful for several reasons: • It helps the family to understand the medical reasons for the death. Requesting an autopsy after the death of a newborn must be handled with sensitivity and gentleness. It can be helpful when it is apparent that a newborn is dying, particularly when the underlying cause is uncertain, to introduce the idea of a postmortem examination to the parents. When an underlying genetic disorder is suspected and premortem testing is incomplete, advance planning for appropriate specimen retrieval with or with out a full autopsy should occur. In every instance, the family should receive the final written results of the autopsy and other examinations in person, if possible, in conjunction with a verbal explanation of the findings. In addition, when there has been an unexpected clinical deterioration leading to a death, a contemporaneous review of the specific clinical events and decisions with all the involved staff participating can be helpful to resolve interpersonal conflicts, relieve feelings of guilt or failure, and improve both understanding and team interaction. In general, such counseling should include the following: • An initial session 4–6 weeks after the death • Assessment of the grieving process • Additional genetic services, if indicated • Review of preliminary autopsy data, if available • Answers for parents’ specific questions • Education and reassurance regarding the normal grieving process • Follow-up visits as indicated by the individual family needs • Referral of family members to bereavement support groups or bereave ment counselors Hospital Discharge of High-Risk Infants ^309^322 Discharge Planning Discharge planning for high-risk infants should begin early in hospitalization and includes six critical elements: 1. The following recommendations are offered as a framework for guiding decisions about the timing of discharge. It is prudent for each institution to establish guidelines that ensure a consistent approach yet allow some flexibility on the basis of physician and family judgment. Infant Readiness the infant is considered ready for discharge if, in the judgment of the respon sible physician, the following have been accomplished: • A sustained pattern of weight gain of sufficient duration has been dem onstrated. Family and Home Environmental Readiness Assessment of the family’s caregiving capabilities, resource availability, and home physical facilities has been completed as follows: • Identification of at least two family caregivers, and assessment of their ability, availability, and commitment • Psychosocial assessment for parenting strengths and risks • Home environmental assessment that may include an on-site evaluation • Review of available financial resources and identification of adequate financial support In preparation for home care of the technology-dependent infant, it is essential to complete an assessment documenting availability of 24-hour tele phone access, electricity, safe in-house water supply, and adequate heating. Specific modification of home facilities must have been completed, if needed, to accommodate home-care systems. Plans must be in place for responding to loss of electrical power, heat, or water, and for emergency relocation mandated by natural disaster. Caregivers should have demonstrated the necessary capabilities to provide all components of care, including the following: • Feeding, whether breast, bottle, or alternative technique, including for mula preparation if required • Basic infant care, including bathing; skin, and genital care; temperature measurement; dressing and comforting Neonatal Complications and Management of High-Risk Infants 373 • Infant cardiopulmonary resuscitation and emergency intervention • Assessment of clinical status, including understanding and detection of the general early signs and symptoms of illness, as well as the signs and symptoms specific to the infant’s condition • Infant safety precautions, including proper positioning during sleep and proper use of car seats (see also “Parent Education and Psychosocial Factors” in Chapter 8) • Specific safety precautions for the artificial airway, if any; feeding tube; intestinal stoma; infusion pump; and other mechanical and prosthetic devices, as indicated • Administration of medications, specifically proper storage, dosage, tim ing, and administration; and recognition of signs of potential toxicity • Equipment operation, maintenance, and problem solving for each mechanical support device required • Appropriate technique for each special care procedure required, includ ing special dressings for infusion entry sites, intestinal stomas, or healing wounds; maintenance of an artificial airway; oropharyngeal and tracheal suctioning; and physical therapy, as indicated. Follow-up care needs must be determined, appropriate physicians identified, and appropriate information exchanged, including the following: • A primary care physician has been identified, and has accepted respon sibility for care of the infant. Within this framework, there are four broad catego ries of high-risk infants that require individual consideration: 1) preterm infants, 2) infants with special health care needs or dependence on technology, 3) infants at risk because of family issues, and 4) infants with anticipated early death. Preterm Infants Criteria for hospital discharge of preterm infants should include physiologic stability rather than attainment of a specific weight. These competencies usually are achieved by 36–37 weeks of postmenstrual age; infants born earlier in gestation and with more complicated medical courses tend to take longer to achieve these physiologic competencies. These infants require close follow-up after discharge to monitor bilirubin concentrations and weight gain (see also “Discharge of Late Preterm Infants” in Chapter 8). Gavage feeding has a limited role and should be considered only when feeding is the last issue requiring continued hospitalization and the parents or caregivers have demonstrated competence and comfort with this procedure. Home parenteral nutrition requires thorough education of caregivers and the availability of a home-care company that is well versed in infant nutritional support and monitoring. Oxygen saturation levels should be assessed intermittently at home to ensure sufficient oxygen is being delivered during a range of activities and sleep. Reducing or stopping supplemental oxygen should be supervised by the physician or other health care professional and attempted only when the infant demonstrates acceptable oxygen saturations (greater than 90%) with good growth velocity and sufficient stamina for usual activity. Home care of the infant with a tracheostomy requires extensive parental teaching and coordinated multidisciplinary follow-up care. If the infant also requires continuing assisted ventilation, home nursing support will be needed for at least part of each day and the ventilator must have a disconnect alarm. Infants at Risk Because of Family Issues Preterm birth, prolonged hospitalization, birth defects, and disabling condi tions are known family stressors and risk factors for subsequent family dysfunc tion and child abuse.

It is also not known at what gestational age testing should be initiated medications that cause pancreatitis purchase 1.5 mg exelon amex, whether testing should be performed once or twice per week treatment 001 exelon 4.5mg generic, or whether there is a need to medications or drugs discount exelon 6mg otc test normally growing dichorionic twins. Early ultrasonography should be used for evaluation of chorionicity, given its importance regarding prognosis and risk of certain complications. Beginning at viability, serial estimations of fetal growth by ultrasonography (every 4–6 weeks after viability, or more closely spaced should indications arise) are a prudent measure because physical exami nation is less reliable. Complications associated with multiple gestations include ges tational diabetes, hypertension and preeclampsia, premature delivery, growth restriction, discordant growth, death of one fetus, and twin–twin transfu sion syndrome. The risks associated with tocolytic agents are amplified in multiple gestations and thus they should be used judiciously. The effect of ante natal steroid administration and the effects of steroid dose in multiple gestations have not been examined. One obvious etiology is pla cental pathology; multiple gestations are at increased risk of having at least one fetus with a suboptimal placental implantation site or abnormal umbilical cord morphology. Likewise, a consultation with an obstetrician–gynecologist with expertise in the management of high-risk pregnancies, such as a maternal–fetal medicine specialist, may be helpful in determining fur ther therapy for these cases when complications arise. No fetal monitoring protocol has been shown to predict the most losses of one fetus in a multifetal pregnancy. However, if the death is the result of an abnormality of the fetus 242 Guidelines for Perinatal Care itself rather than maternal or uteroplacental pathology and the preg nancy is remote from term, expectant management may be appropriate. Whether to reduce high-order multiple gestations to twin or triplet gestations and whether to reduce triplet gestations at all are both areas of controversy. The risks of this procedure are higher than those associated with multifetal reduction, in part because the pregnancy is often more advanced at the time of diagnosis of the anomaly. If the reduced fetus overlies the cervix or if the pregnancy is beyond 20 weeks, the risk of pregnancy loss, preterm delivery, or low birth weight of the remaining fetus may be increased. A variety of therapies have been attempted, including serial therapeutic amniocente ses of the recipient twin’s amniotic sac. These cases should be performed in centers experienced with the procedures, monitored very closely, and managed in consultation with a maternal–fetal medicine specialist. However, no prospective randomized trials have tested the hypothesis that elective delivery at these gestational ages improves outcomes in these pregnancies. However, recent guidelines based on available data and expert opinion have recommended delivery at 38 weeks of gestation in uncomplicated dichorionic diamniotic twin pregnancies and at 34–37 weeks of gestation in uncomplicated monochorionic-diamniotic twin pregnancies. Data are insufficient to determine the best route of delivery for high-order multiples. Other Medical Complications During Pregnancy Antepartum Hospitalization Pregnant patients with complications who require hospitalization before the onset of labor should be admitted to a designated antepartum area, either inside or near the labor and delivery area. When sufficiently recovered, the pregnant patient should be returned to the obstetric service, provided that her return does not jeopardize her care. When feasible, 244 Guidelines for Perinatal Care antepartum transfer to specialty or subspecialty perinatal care centers should be encouraged for these women (see also “Transfer for Critical Care” in Chapter 4). Written policies and procedures for the management of pregnant patients seen in the emergency department or admitted to nonobstetric services should be established and approved by the medical staff and must comply with the requirements of federal and state transfer laws. When warranted by patient vol ume, a high-risk antepartum care unit should be developed to provide special ized nursing care and facilities for the mother and the fetus at risk. When this is not feasible, written policies are recommended that specify how the care and transfer of pregnant patients with obstetric, medical, or surgical complications will be handled and where these patients will be assigned. The evaluation should encom pass a complete review of current illnesses as well as a medical, family, and social history. The condition of the patient and the reason for admission should deter mine the extent of the physical examination performed and the laboratory stud ies obtained. A copy of the patient’s current prenatal record should become part of the hospital medical record as soon as possible after admission. These policies also must comply with the requirements of federal and state transfer laws. Critical Care in Pregnancy Approximately 1–3% of pregnant women require critical care services in the United States each year, with the risk of death ranging from 2% to 11%. Obstetric and Medical Complications 245 Intrapartum Care If a laboring patient requires critical care services, it is important to determine the optimal setting for her care. If the fetus is previable or the maternal condition unstable, it may be appropriate to undergo vaginal delivery in the intensive care unit. Intravenous analgesia may be used but is less effective in treat ing pain (see also “Analgesia and Anesthesia” in Chapter 6).

The aberrant left ventric ular trabeculae predispose to 2 medications that help control bleeding proven 6mg exelon abnormal cardiac conduction and potentially fatal cardiac arrhythmias treatment 2nd degree heart block buy genuine exelon line. The interstices within the trabeculated left ventricle predispose to medicine 5e 1.5 mg exelon for sale thrombus formation with secondary systemic embolic events. Fibroelastosis of the adjacent ventricular endothelium is a secondary phe nomenon resulting from the abnormal blood ow pattern in the left ventricu lar chamber. Mortality is presumably due to cerebral hypoperfusion during a malignant ventricular tachycardia known as torsades de pointes. The standard four-chamber view of the heart is obtained at an approximate 45 angle from the view used to obtain the abdominal circumference view. Two other views are necessary to fully evaluate the heart: the left ventricular outow view and short axis great vessel views. They are usually obtained by rotating the axis of the transducer from the four-chamber view by 30–45 to the right or left, resulting in imaging planes that transect the scapulla and torso at 30–45 angles from the midsagittal plane. The cardiac axis (the axis of the intraventricular septum) should approxi mate 45 from the midsagittal plane. Cardiac axis angles greater or less than these values indicate possible cardiac abnormalities or “mass effect” from intrathoracic masses or abnormalities. The membranous septal portion of the intraventricular septum, located immediately adjacent to the crux, is anatomically very thin. The four-chamber view • Symmetric atria and ventricles, intraatrial and intraventricular septa, the foramen ovale, the ap of the foramen ovale oriented into the left atrium, and the axis is to the left at approximately a 45 angle to the sagittal plane. The ve-chamber view • Modication of the four-chamber imaging plane in which the aortic root origin in the left ventricle is imaged (one chamber) as well as accompanying views of the other four standard chambers giving a “ve-chamber view. The left ventricular outow tract view • Shows left atrium, left ventricle, the mitral valve, and the aorta. The right ventricular outow tract view • Shows the right ventricle, the pulmonic valve, the pulmonary artery, and a portion of the ductus arteriosus. The rising aortic arch often is seen in transverse section immediately adjacent to the pulmonary artery. The short axis (“hurricane”) great vessel view • Shows the right cardiac structures (right atrium, tricuspid view, right ventricle, and pulmonic valve) arrayed circumferentially around the aortic root, with the bifurcation of the pulmonary artery into the ductus,andtherightpulmonaryarteryisclearlyseen. The triple leaf pattern of the aortic valve (resembling the letter Y or a Mercedes-Benz emblem) oftenisseen. Crossing views of the pulmonary artery and aorta • the pulmonary artery and right outow tract often can be shown to cross the aorta and left ventricular outow tract in a transverse fashion approximately at a 30 angle. The aortic arch • Begins centrally within the heart, initially crosses from left to right, thencurvesfromrighttoleft,travelssomewhatanteriorlytoformthe transversearch,andthencontinuescurvinginteriorlyandposteriorly to form the descending aorta. The ductal arch • the ductus arteriosus is much more prominent in fetuses than in infants after birth because it is the bridge that allows the nor mally parallel pulmonary and aortic circulatory systems to develop and function in the absence of signicant volume ow through the lungs. Cardiac abnormalities in some studies have found that 30% have chromo somal abnormalities a. Dysrhythmias – Both bradyarrhythmias and tachyarrhythmias are occa sionally noted on auscultation or direct observation of the fetal heart. Transient bradycardias are often seen as a result of maternal supine po sitioning during routine sonographic evaluation. They can be avoided by repositioning the patient in a lateral position when symptoms of warmth and faintness develop. These ndings are usually a result of the predisposition toward maternal supine hypotension in pregnancy. Transient bradycardia usually occurs in association with maternal hy potensive symptomatology and resolves without recurrence after po sitional change. For recurrent or persistent bradycardia, fetal distress should be excluded and further evaluation or consultation should be considered.
