Enteral therapy refers to feeding via the gut asthma definition reversible buy 500 mcg fluticasone, using oral supplements or infusion of formulas via various feeding tubes (nasogastric, nasoduodenal, gastrostomy, jejunostomy, or combined gastrojejunostomy). Parenteral nutrition is often indicated in severe pancreatitis, necrotizing enterocolitis, prolonged ileus, and distal bowel obstruction. Yes What are the fluid, energy, mineral, and vitamin requirements and can these be provided enterally? Support patient with general comfort measures including oral food and liquid supplements if desired. The major risks of enteral tube feeding are aspiration, diarrhea, electrolyte imbalance, warfarin resistance, sinusitis, and esophagitis. The risks of parenteral therapy include mechanical complications from insertion of the infusion catheter, catheter sepsis, fluid overload, hyperglycemia, hypophosphatemia, hypokalemia, acid-base and electrolyte imbalance, cholestasis, metabolic bone disease, and micronutrient deficiencies. In acute blood loss, hematocrit may not accurately reflect degree of blood loss for 48 h until fluid shifts occur. Removal of leukocytes reduces risk of alloimmunization and transmission of cytomegalovirus. Irradiation prevents graft-versus-host disease in immunocompromised recipients by killing alloreactive donor lymphocytes. Other Indications (1) Hypertransfusion therapy to block production of defective cells. One unit elevates the count by about 10,000/ L if no platelet antibodies are present as a result of prior transfusions. Leukapheresis is replacing bone marrow aspiration to obtain hematopoietic stem cells. After treatment with a chemotherapeutic agent and granulocytemacrophage colony-stimulating factor, hematopoietic stem cells are mobilized from marrow to the peripheral blood; such cells are leukapheresed and then used for hematopoietic reconstitution after high-dose myeloablative therapy. Heart disease and cancer are the two leading causes of death and together account for nearly half of all deaths. About 70% of deaths occur in people who have a condition that is known to be leading to their death; thus, planning for terminal care is relevant and important. An increasing fraction of deaths are occurring in hospices or at home rather than in the hospital. Optimal care depends on a comprehensive assessment of pt needs in all four domains affected by illness: physical, psychological, social, and spiritual. Physicians must be clear about the likely outcome of the illness(es) and provide an anticipated schedule with goals and landmarks in the care process. When the goals of care have changed from cure to palliation, that transition must be clearly explained and defended. Ensure that the medical information is as complete as possible and understood by all relevant parties. Advance Directives Only 29% of pts (and less than one-third of physicians) have executed advance directives that define the level of intervention the pt is willing to accept. Forms are available free of charge from the National Hospice and Palliative Care Organization ( Physical Symptoms and Their Management the most common physical and psychological symptoms among terminally ill pts are shown in Table 10-1. Studies of pts with advanced cancer have shown that pts experience an average of 11. Medications commonly contribute to constipation, including opioids used to manage pain and dyspnea, and tricyclic antidepressants with their anticholinergic effects. Interventions Improved physical activity (if possible), adequate hydration; opioid effects can be antagonized by the -opioid receptor blocker methylnaltrexone; rule out surgically correctable obstruction; laxatives and stool softeners (Table 10-2). Nausea from cancer chemotherapy agents can generally be prevented with glucocorticoids and serotonin receptor blockers like ondansetron or dolasetron. Aprepitant is useful in controlling nausea from highly emetogenic agents like cisplatin. Vestibular nausea may respond to antihistamines (meclizine) or anticholinergics (scopolamine).

After reaching the uterus asthma treatment drugs discount fluticasone 100 mcg buy, the developing zygote remains freely in the uterine cavity for 2 to 4 days before it is implanted asthma 7 news generic fluticasone 500 mcg line. During the stay in uterine cavity before implantation asthma treatment 4 high blood cheap 100 mcg fluticasone fast delivery, the zygote receives its nutrition from the secretions of endometrium asthma treatment differences cheap fluticasone 100 mcg with visa, which is known as uterine milk. Just before implantation, the zygote develops into morula and then the implantation starts. During fertilization of ovum, 23 chromosomes from ovum and 23 chromosomes from the sperm unite together to form the 23 pairs (46) of chromosomes in the fertilized ovum. When implantation occurs, there is further increase in the thickness of endometrium because of continuous secretion of progesterone from corpus luteum. At this stage, the endometrial stromal cells are called decidual cells and the endometrium at the implanted area is called decidua. Now the trophoblastic cells of morula develop into cords, which are attached with decidual portion of endometrium. Blood capillaries grow into these cords from the blood vessels of the newly formed embryo. At about 16th day after fertilization, heart of embryo starts pumping the blood into the trophoblastic cords. Fetal part of placenta contains the two umbilical arteries, which carry fetal blood to the placental villi through the capillaries. Maternal part of placenta is formed by uterine arteries through which blood flows into sinusoids that surround the villi. Histological changes Endometrium shows formation of decidua, which is the bed for the fertilized ovum during the initial stages of pregnancy. Vagina Vagina increases in size and its color changes to violet due to increased blood supply. Cervix In cervix, the number of glands, blood supply and mucus secretion increase. Fallopian Tube the number of epithelial cells and blood supply increase in fallopian tubes. Mammary Glands Size of the mammary glands increases because of development of new ducts and alveoli, deposition of fat and increased vascularization. Corpus luteum enlarges and secretes a large quantity of progesterone and little estrogen, which are essential for maintaining the pregnancy. By this time placenta develops fully and takes over the function of secreting estrogen and progesterone. Uterus When the fetus grows, uterus undergoes changes in volume, size, shape and weight. From almost zero volume, uterus reaches about 5 to 7 liters at the end of pregnancy. Out of this, 50% of the volume is due to the fetus and rest is due to the placenta, amniotic fluid, etc. Basal Metabolic Rate Increase in the secretion of various hormones especially thyroxine increases the basal metabolic rate by about 15% in the later stages of pregnancy. Because of all these reasons, there is hyperplasia of beta cells of islets of Langerhans in pancreas leading to increase in secretion of insulin. Inspite of this, there is possibility of developing diabetes in pregnancy or latent diabetes after delivery. Lipid Metabolism During pregnancy, there is deposition of about 3 to 4 kg of fat in the maternal body. Water and Mineral Metabolism Estrogen and progesterone are secreted by corpus luteum in the first trimester and by placenta later. Apart from water and sodium retention, there is retention of calcium and phosphorus as well. Because of great demand for iron by the fetus, the mother usually develops anemia.
