During pregnancy only minimal amounts of milk transfer from the breast to the baby as on adequate milk are formed in the breast despite high levels of the milk secretion. The milk ejection reflex is mediated by 442 Postnatal Care Prolactin release the release of oxytocin from the posterior pituitary gland (see. Oxytocin causes contraction of the sensitive myoepithelial cells that are situated around? In contrast to Prolactin prolactin, which is secreted only in response to suck- (in blood) ling, oxytocin can be released in response to sensory inputs such as the mother seeing the baby or hearing its cry.

The milk ejection reflex is readily inhibited by emotional stress and this may explain why maternal anxiety frequently leads to failure of lactation. Successful breastfeeding depends on engendering con- fidence in the mother and ensuring correct fixing and. Another factor is of potential physiological importance as an inhibitor of breast milk: if the milk is not effectively Milk-ejection reflex stripped from the breast at each feed, this will inhibit lac- topoiesis and lead to a fall in milk production.

Embolization successfully controls bleeding in 52% to 94% of patients purchase generic tadacip erectile dysfunction protocol free download pdf, with approximately 10% of these patients requiring repeat embolization for recurrent bleeding [57] cheap tadacip 20mg free shipping erectile dysfunction pills at cvs. There is a risk of bowel ischemia following embolization, but this is usually minor and self- limited [55]. Angiotherapy can be comparable to surgical intervention when endoscopic therapy fails for bleeding peptic ulcers. A retrospective analysis demonstrated no difference between embolization and surgery in recurrent bleeding (29. The timing for the use of angiography and angiotherapy must be individualized and usually is a consensus decision by the involved physicians. Surgical Therapy the appropriate timing of when a surgeon should be involved in the care of a bleeding patient is physician and institution dependent, and ranges from an early team approach at presentation to involvement once the risk of significant morbidity and mortality are established after a poor response to medical and endoscopic therapy. Surgical intervention is an effective and safe alternative for patients with uncontrollable bleeding or those unable to tolerate additional bleeding [59]. Prior to surgical intervention, a repeat endoscopy for a patient with persistent or recurrent bleeding can be considered owing to lower risks of side effects from endoscopy compared to surgery [60,61]. A possible exception may be ulcers >2 cm in hypotensive patients where the risk of rebleeding is extremely high with repeat endoscopic therapy [26,61]. Patients with massive hemorrhage that overwhelms the resuscitation effort may need to proceed directly to the surgical suite during ongoing resuscitation. If these patients are high-risk surgical candidates, angiotherapy or a percutaneously or surgically placed portal-hepatic shunt for variceal bleeding may be alternatives. Bleeding from gastroesophageal varices characteristically is brisk and typically presents as hematemesis, melena, or hematochezia in association with hemodynamic instability. The presentation may be less dramatic because acute blood loss can be self- limited in 50% to 60% of cases [62]. Once active bleeding stops, the likelihood of recurrent variceal hemorrhage is 40% within 72 hours and 60% within 10 days if no definitive treatment is pursued [48]. Risk factors associated with variceal rupture include a portal pressure gradient greater than 12 mm Hg, large variceal size (greater than 5 mm), and progressive hepatic dysfunction [66]. Endoscopic findings that implicate esophageal or gastric varices as the bleeding source include the red sign, where one varix is brighter red than the others from microtelangiectasia (red-sign variants include red- wale marks, cherry-red spots, hematocystic spots, and diffuse redness of varix), and the white-nipple sign, in which a fresh fibrin clot may be seen protruding from a varix [66,67]. Endotracheal intubation protects the airway from aspiration of blood in obtunded patients, especially in the setting of massive bleeding [68]. Additional complications that must be addressed include alcohol withdrawal, aspiration, infection, and electrolyte imbalances. Octreotide is a somatostatin analog that decreases splanchnic blood flow and portal pressure, controlling variceal bleeding in as many as 85% of patients [69,70] with an efficacy approaching that of endoscopic therapy and providing improved visibility during subsequent endoscopy [70–72]. Aside from transient nausea and abdominal pain with bolus doses, significant adverse effects from octreotide are rare. Vasopressin, once widely used in this setting, has a significant cardiovascular side effect profile and for this reason has been replaced by octreotide. Endoscopic evaluation should be performed urgently (within 12 hours) in patients in whom variceal bleeding is suspected [79]. Endoscopic band ligation has gained acceptance as the preferred endoscopic treatment for patients with bleeding esophageal varices, with rapid obliteration of varices, and low rates of complications and rebleeding (Table 203. Endoscopic variceal sclerotherapy (injecting a sclerosing solution into the variceal lumen or into the adjacent submucosa), although successful in controlling variceal bleeding, is associated with a 20% to 40% incidence of complications, and has largely been relegated to a second-line therapeutic modality, reserved for patients in whom band ligation is technically difficult [66,81]. Complications of band ligation include recurrent bleeding from treatment-induced esophageal ulcers, stricture formation, esophageal perforation, and acceleration of portal hypertensive gastropathy [82]. Repeat variceal band ligation is performed until varices are obliterated because this approach reduces the incidence of rebleeding [66]. Appropriate interval for repeat band ligation is controversial, with recommendations ranging from 1 to 8 weeks [79]. Gastric varices are detected in approximately 20% of patients with portal hypertension, but can also occur from splenic vein thrombosis. Gastric varices bleed less often, but blood loss can be more substantial compared to esophageal varices [83]. Complications include a propensity for embolic phenomenon posttreatment, including massive pulmonary embolism [85]. Embolization of the short gastric veins and varices is a potential management option for isolated gastric varices. Complications include transient deterioration of liver function, new or worsened hepatic encephalopathy (25%), and shunt insufficiency from thrombosis or stenosis [86]. When placed in an emergency setting to control active bleeding, a 10% in-hospital mortality and 40% 30-day mortality have been reported [86,88,89]. This technique requires a natural gastrorenal or gastrophrenic shunt, which occur in 95% of cases of gastric varices [90]. A balloon catheter is used to occlude the shunt, following which a sclerosant, for example, ethanolamine is injected into the varix [90]. A recent meta-analysis found a pooled clinical success rate of 97% with a major complication rate of 2. Surgically created shunts reliably control acute bleeding (>90%) and prevent rebleeding (<10%) [92,93] but are limited by high operative mortality and postprocedure encephalopathy. Therefore, surgical shunts are only considered in well-compensated cirrhotic patients with good long-term prognoses [93]. Esophageal or gastric balloon devices may be used for direct tamponade of the bleeding source when definitive therapy is not immediately available. There are two basic types of balloon tubes: those with gastric and esophageal balloons (Sengstaken–Blakemore and Minnesota tubes) and those with a large gastric balloon alone (Linton– Nachlas). Other complications (aspiration, balloon migration, airway occlusion, perforation, pressure necrosis) occur in 15% to 30% of patients, including death in 6% [94]. Instructions for correctly placing and maintaining a specific balloon device are included as a product insert and should be reviewed before balloon use. Other cofactors, including older age, a history of past peptic ulcers (especially with ulcer bleeding), and a history of coronary disease, may be independent risk factors for ulcer bleeding [96,97]. In a proportion of patients, the disorder remains idiopathic, because of either an inability to demonstrate H. A recent meta-analysis demonstrated a clear relationship between presence of comorbid conditions and risk of death from peptic ulcer bleed [102]. Other prognostic information can be obtained from endoscopy findings, which should detail whether stigmata of recent bleeding (active bleeding, nonbleeding visible vessel, adherent clot, flat pigment spots) or no stigmata (clean ulcer base) were found in association with the ulcer (Table 203. These criteria can be used to predict rebleeding and the need for therapeutic intervention [46,101,103]. Patient age, hemodynamic parameters, comorbidities, and endoscopic findings have been compiled into scoring system by Rockall et al. In vitro data suggest that gastric acid plays an important role in impairing platelet aggregation, clot lysis, and increased fibrinolytic activity that is reversible at pH values above 6 to 6. This approach has been demonstrated to be cost effective, reducing the need for endoscopic therapy by 7. The classic history is a patient with vomiting of nonbloody gastric contents followed by hematemesis, although this presentation is variable (29% to 86%) [113].
