All rights reserved 2 Prenatal Care: Your First Visit Why is prenatal care importantfi Regular appointments with your health care provider throughout your pregnancy are important to ensure the health of you and your baby. In addition to medical care, prenatal care includes education on pregnancy and childbirth, plus counseling and support. Most health care providers welcome your partner at each visit, as well as interested family members. The first visit is designed to determine your general health and give your health care provider clues to the risk factors that might affect your pregnancy. Also, notify your health care provider about any medications (prescription or over-the-counter) you have taken or are currently taking. We ask some very personal questions, but be assured that any information you give is strictly confidential. Pelvic exam During the pelvic exam, a bimanual internal exam (with two fingers inside the vagina and one hand on the abdomen) will be performed to determine the size of your uterus and pelvis. How is my expected date of Lab tests Many lab tests are ordered in your delivery determinedfi A very (protection) against German small number of babies are actually measles born on their due dates. During prenatal care visits, your weight and blood pressure will be checked, and a urine sample will be tested for sugar and protein. Additional tests might be required, depending on your individual condition or special needs. During the last month, your office visits will include discussions about labor and delivery. Your office visits may include an internal examination to check your cervix (the lower end of your uterus) for thinning (called effacement) and opening (called dilation). While there are two of you now, you only need to increase your calorie intake by 500 calories. This guide will help you choose a variety of healthy foods for you and your baby to get all the nutrients you need. You will need an additional 200 to 300 extra calories from nutrient-dense foods such as lean meats, low fat dairy, fruits, vegetables and whole grain products. It will be important to carefully consider the foods you consume during your pregnancy. This is a time to eat more foods that are nutrientdense, and fewer sweets and treats. Calcium also allows the blood to clot normally, nerves to function properly, and the heart to beat normally. Other sources of calcium are dark, leafy greens, fortified cereal, breads, fish, fortified orange juices, almonds, and sesame seeds. The March of Dimes suggests that 70 percent of all neural tube defects can be avoided with appropriate folic acid intake. Some women are at an increased risk for having a baby with an open neural tube defect (including but not limited to women with a family history of spina bifida, women on anti-epileptic medication, etc. It also is essential lentils, kidney beans, green leafy for healthy skin and eyesight.

In ischaemia-hypoxia, perfusion of Middle and anterior cerebral arteries have partial overlapping zones, being farthest from the blood supply, anastomosis of their distal branches. Particularly vulnerable is the border zone of the arteries and have no anastomosis. Hence, occlusion of these cerebral cortex between the anterior and middle cerebral branches will invariably lead to an infarct.

Microscopically, the nerve cells die and disappear and are replaced by reactive fibrillary gliosis. Grossly, cerebral infarcts variations in the distribution of neuronal damage to the may be anaemic or haemorrhagic. The affected area is soft and swollen and there is blurring of junction between grey and white matter. The histologic firm glial reaction and thickened leptomeninges, forming changes are reactive astrocytosis, a few reactive macrophages and neovascularisation in the wall of the cystic lesion.

About 40% of patients die during the first 3-4 vessels and has peripheral fibrillary gliosis. Small cavidays of haemorrhage, mostly from haemorrhage into the tary infarcts are called lacunar infarcts and are commonly ventricles. The survivors tend to have haematoma that found as a complication of systemic hypertension. There are two main types of copically, the haemorrhage consists of dark mass of spontaneous intracranial haemorrhage: clotted blood replacing brain parenchyma. Intracerebral haemorrhage, which is usually of hyperof the lesion are sharply-defined and have a narrow rim tensive origin. Subarachnoid haemorrhage, which is commonly aneurhages in the Virchow-Robin space in the border zone are rysmal in origin. Ipsilateral ventricles are distorted and In addition to hypertension and rupture of an aneurysm, compressed and may contain blood in their lumina. After a few weeks to months, intracerebral and subarachnoid haemorrhage, haemorrhagic the haematoma undergoes resolution with formation of a diathesis and haemorrhage into tumours. Its margins are yellow-brown and have are the result of rupture in the posterior circulation, vascular haemosiderin-laden macrophages and a reactive zone of malformations and rupture of mycotic aneurysms that occurs fibrillary astrocytosis.

The region of the brain supplied by the wall at the bifurcation of arteries forming thin-walled saccuaffected artery frequently shows infarction, partly lar bulges. Important In more than 85% cases of subarachnoid haemorrhage, causes of head injuries are: motor vehicle accidents, the cause is massive and sudden bleeding from a berry accidental falls and violence. The four most may result in three consequences which may occur in common sites are as under (Fig. At the origin of the posterior communicating artery from subdural haematoma; and the stem of the internal carotid artery. Epidural haematoma is accumulation of blood between the dura and the skull following fracture of the skull, most commonly from rupture of middle meningeal artery. The haematoma expands rapidly since accumulating blood is arterial in origin and causes compression of the dura and flattening of underlying gyri (Fig. The patient develops progressive loss of consciousness if haematoma is not drained early. Subdural Haematoma Subdural haematoma is accumulation of blood between the dura and subarachnoid and develops most often from rupture of veins which cross the surface convexities of the cerebral hemispheres. Acute subdural haematoma develops following trauma and consists of clotted blood, often in the frontoparietal region.

These common cause of persistent coma or vegetative state conditions have known etiologies such as: geneticallyfollowing head injury. The underlying cause is sudden determined defects in the myelin metabolism (leucodysangular acceleration or deceleration resulting in widespread trophies), slow virus diseases of oligodendrocytes (proaxonal shearing in the deep white matter of both the gressive multifocal leucoencephalopathy), and exposure to hemispheres. All these entities are Grossly, the changes are minimal to small multiple currently not classified as demyelinating diseases.

This package will provide an overview of most cardiac arrhythmias and the mechanism that causes them. This package will provide information on in regards to the different arrhythmias and the abnormalities that causes them such as electrical instability in the myocardial cell membrane, the ability of cardiac cells contract twice, although they only have been activated once and the propagation through issues rather than abnormalities in physiology of individual cells. The goal of this module is to review: Arrhythmia etiology Arrhythmia pathophysiology the different mechanisms of Arrhythmias Defining the different types of arrhythmias. Learning outcomes for this module are: To identify the different clinical manifestations of arrhythmias. To state what is define as normal automaticity To state what is define as abnormal impulse imitation. To state what is define as abnormal impulse conduction To identify the arrhythmias in relation to each mechanisms. Life threatening arrhythmias that is not controlled, can affect the heart ability to pump enough blood to the body. This can cause a lack of blood flow that can damage vital organs, such as the brain, heart. At this point, the signal slows down just a little, allowing the ventricles time to finish filling with blood. The signal goes down these branches to the ventricles, causing them to contract and pump blood out to the lungs and the rest of the body. The problem is if there is any delay or blocks at any part of this process, an arrhythmia can develop. An arrhythmia also can occur when another part of the heart starts to produce electrical signals, adding to the signals from the special nerve cells and disrupting the normal heartbeat. Stress, smoking, heavy alcohol use, heavy exercise, use of certain drugs (such as cocaine or amphetamines), use of certain prescription or over-the-counter medicines, and too much caffeine or nicotine can lead to arrhythmia in some people. These conditions include high blood pressure (hypertension), coronary artery disease, heart failure, overactive or underactive thyroid gland (too much or too little thyroid hormone produced), and rheumatic heart disease. For some arrhythmias, such as Wolff-ParkinsonWhite syndrome, the underlying heart defect that causes the arrhythmia is present at birth (congenital). Atrial fibrillation is the most common type of cardiac arrhythmia found in adults today, affecting over 5. Because of heart disease and other health problems that can lead to arrhythmias, adults older than 60 are affected by some of the more serious arrhythmias. Where other arrhythmia happen more often in children and young adults, such as paroxysmal supraventricular tachycardia (a fast heart rate that begins and ends suddenly), including Wolff-Parkinson-White syndrome. The heart organ broadly differentiates into two types of cell, pacemaker cells, and non-pacemaker cells. Pacemaker cells beat with their own independent rhythm, in synchrony with their neighbours (a heart attack results when these cells get out of synch with each other). The non-pacemaker cells require stimulus to beat, this stimulus comes from the pacemaker cells. Incorrect impulse generation is the fault of the pacemaker cells, which are beating either too slow, too fast, or not totally in rhythm. A re-entry pathway occurs when a section of nervous tissue (which conducts the impulse) is damaged in some manner. Part of the tissue only conducts the impulse in a single direction, in the example shown left this is in the opposite direction to the genuine impulse direction. This will set up a loop in the nervous tissue, as the impulse keeps going round and round the junction, stimulating the non-pacemaker cells to contract, and ultimately disturbing the rate of heartbeat. These include enhanced or suppressed automaticity, triggered activity, or reentry. Ischemia, scarring, electrolyte disturbances, medications, advancing age, and other factors may suppress or enhance automaticity in various areas. Suppression of automaticity of the sinoatrial node can result in sinus node dysfunction and sick sinus syndrome. Sick sinus syndrome is still the most common indication for permanent pacemaker implantation. In contrast to suppressed automaticity, enhanced automaticity can result in multiple arrhythmias, both atrial and ventricular. Triggered activity occurs when early afterdepolarizations and delayed afterdepolarizations initiate spontaneous multiple depolarisations precipitating ventricular arrhythmias. Examples of this include torsades de pointes and ventricular arrhythmias due to digitalis toxicity. Finally, probably the most common mechanism of arrhythmogenesis results from re-entry. Requisites for re-entry include bi-directional conduction and uni-directional block. Hypernatremia (high sodium level) may result in an erratic heart rate as sodium and calcium ions compete with one another to influence the heart. Imbalances in potassium and magnesium, however, are the usual culprits of cardiac arrhythmia when an electrolyte imbalance occurs. Hyperaemia (high potassium levels) initially causes tachycardia and then bradycardia as the heart fatigues in response to the high sustained heart rate and weak cardiac contraction. In summary, arrhythmias may be caused by many different factors, including: (1) Coronary artery disease; (2) Electrolyte imbalances in your blood (such as sodium or potassium); (3) Changes in your heart muscle; (4) Injury from a heart attack; (5) Healing process after heart surgery. But also remember this, Irregular heart rhythms can also occur in "normal, healthy" hearts. The signs and symptoms of cardiac arrhythmias can range from completely asymptomatic to loss of consciousness or sudden cardiac death. In general, more severe symptoms are more likely to occur in the presence of structural heart disease. Complaints such as light-headedness, dizziness, quivering, shortness of breath, chest discomfort, heart fluttering or pounding, and forceful or painful extra beats are commonly reported with a variety of arrhythmias. Frequently patients notice their arrhythmia only after checking peripheral pulses. Certain symptoms raise the index of suspicion and can give clues to the type of arrhythmia. Such tachycardias may frequently be accompanied by chest discomfort, diaphoresis, neck fullness, or a vasovagal type of response with syncope, diaphoresis, and nausea. Syncope in the setting of noxious stimuli such as pain, prolonged standing, and venepuncture, particularly when preceded by vagal-type symptoms (diaphoresis, nausea, vomiting), suggests neurocardiogenic (vasovagal) syncope. Abnormal impulse initiation includes enhanced normal automaticity, abnormal automaticity and triggered activity resulting from afterdepolarization. Although all these mechanisms have been shown to cause arrhythmias, it is not possible to prove which mechanism is responsible for a particular arrhythmia. Although automaticity is an intrinsic property of all myocardial cells, the occurrence of spontaneous activity is prevented by the natural hierarchy of pacemaker function. The emergence of subsidiary or latent pacemakers under such circumstances is an appropriate fail-safe mechanism which assures that ventricular activation is maintained. Enhanced normal automaticity: refers to the accelerated generation of an action potential by either normal pacemaker tissue (enhanced normal automaticity) or by abnormal tissue within the myocardium (abnormal automaticity). The discharge rate of normal or abnormal pacemakers may be accelerated by drugs, various forms of cardiac disease, reduction in extracellular potassium, or alterations of autonomic nervous system tone. Abnormal automaticity: refers to the development of a site of depolarisation in nonpacemaker tissue usually in Purkinje fibres or myocardial cells. This occurs because of the inability of these cells to maintain a constant resting potential, but to decline gradually to reach a threshold potential;. In cases, where a person collapses on exertion with aortic stenosis, the compensatory left ventricular hypertrophy causes cell hypoxia. This is cause because when the heart rate increases (less diastolic coronary flow) and the sudden exercise catecholamines are released. Arrhythmias arising from the sinus node Because the sinus node is the dominant pacemaker of the heart, alterations in its rate may lead to arrhythmias. Sinus tachycardia results when the sinus node fires at rates in excess of 100 beats per minute. Conversely, sinus bradycardia occurs when the sinus node fires at less than 60 beats per minute. Sinus tachycardia can be the appropriate response to external factors such as exercise, fever, or hypotension. In well-conditioned athletes, sinus bradycardia can be the normal response to exercise-increased parasympathetic stimulation. In the average person, however, sinus bradycardia more often reflects an abnormality of the sinus node and escape pacemakers due to disease, abnormalities in parasympathetic stimulation, or outside factors such as drugs. Arrhythmias arising from ectopic pacemakers Arrhythmias due to automaticity also result when the site of dominant pace making shifts from the sinus node to any ectopic (nonsinus) pacemaker. Sinus node dominance can be compromised in several ways: sinus node suppression of subsidiary pacemakers may be reduced, inhibitory influences between nonpacemaker and pacemaker cells may be removed, or secondary pacemakers may be enhanced so that they fire faster than the sinus node. One occurs early during the repolarisation of the membrane, an early afterdepolarization, and the other occurs after the repolarisation is complete or nearly complete, a delayed afterdepolarization. When either type is large enough to reach threshold, the resulting action potential is called a triggered action potential. Triggered activity, therefore, differs from automaticity in that at least one action potential (the trigger) comes before the train of pulses. Automatic rhythms can arise spontaneously following long periods lacking in electrical activity; whereas, triggered rhythms cannot arise spontaneously. Triggered activity will cause arrhythmias when impulse initiation shifts from the sinus node to the triggered focus. For this, the rate of triggered impulses must be faster than the rate of the sinus node, an event that may be brought about when the sinus node has been slowed or inhibited, when it has been blocked, or when the triggered focus is intrinsically faster. They appear as sudden positive changes in membrane potential; instead of following the normal course of repolarisation, the membrane suddenly shifts toward depolarization. This shift can result from any factor that decreases outward current (carried by K+) or increases the inward current (carried by Na+ or Ca2+). Arrhythmias caused by delayed afterdepolarizations Delayed afterdepolarizations can reach threshold to cause triggered action potentials especially if the rate of stimulation is fast enough. Introduction of catecholamines into the canine coronary sinus causes atrial tachycardia with the characteristics of triggered activity. Conduction block Block of cardiac impulses can occur under several different scenarios. An impulse may arrive at tissue that is unexcitable because the tissue is still refractory after a recent depolarization or because the tissue is abnormally depolarized. It may also occur because tissue is intrinsically unable to conduct (scar tissue from prior infarct or surgical incision). Normally, if the sinus impulse fails to propagate to right atrium (sinus node exit block or sinoatrial block), an ectopic pacemaker will take control of the heart. Under some conditions, however, an escape pacemaker may not arise quickly enough or at a clinically significant rate. A period of asystole (an absence of electrical or mechanical activity), marked bradycardia or both may appear. A special form of block, unidirectional block, will be discussed in detail in the next section. The impulse does not usually conduct backwards because the tissue just stimulated is refractory and, therefore, unable to generate a second action potential. As a result, the normal heart must wait for new sinus pulse for each subsequent heart beat. Reentry occurs when the action potential does not die out but continues to propagate and reactivate the heart. Reentry can occur almost anywhere in the heart and can assume many sizes and shapes. All other measurements and aspects of the rhythm would be consistent with what is described under Normal Heart Rhythm. Sinus dysrhythmia is divided into two categories, respiratory (related to breathing) and no respiratory.

You should not lift anything heavy (anything you have to strain to lift) for 1 month after surgery. This is due in part to the gas used at laparoscopy, but more so to the sutures placed in the diaphragm muscle; and should gradually resolve. It may be difficult/uncomfortable to take a deep breath or lie flat immediately after surgery as breathing uses the diaphragm muscle. You may take Acetaminophen (Tylenol) and/or anti-inflammatories (such as ibuprofen or naprosyn) as directed on the package in addition to the pain medication if needed. You may discontinue any heartburn medication: Prilosec, Prevacid, Pepcid, Zantac,etc. You have a prescription for an anti-nausea medication such as prochlorperazine (Compazine). If you have an urgent issue that cannot wait until normal office hours, please call the office 303-788-7700 and Dr. You should be swallowing at least mushy, soft food as soon as possible (applesauce, yogurt, saltine crackers with sips of water, cottage cheese are examples). Each patient tolerates different consistencies at different times of their recovery, and some patients have no difficulty swallowing after surgery. Gradually increase the consistency of your diet over the next weeks as your body permits. To stretch the scar tissue swallow a few tablespoons of yogurt consistency or thicker food every hour while you are awake for the first 4-6 weeks after surgery. This can be uncomfortable at times, but is the most important part of your recovery, so keep doing it even if uncomfortable. If food seems to be hanging up, slow down and wait at least 1 minute between bites. Large bites are likely to have a harder time going down, and are more likely to lead to spasms or hiccups. Cold liquids lead to the weakest pressures (meaning more difficult for things to go down). A few weeks after surgery (generally 2-4 weeks), scar tissue temporarily thickens. Please let us know if you are not able swallow yogurt consistency most (over 50%) of the time. If you are still having problems swallowing them, you can check with your pharmacist and see if you can crush or break them. Hold off on large vitamins or supplements until you are swallowing without difficulty. Spasm is most often due to food getting stuck in the lower esophagus though sometimes will occur spontaneously. Although it can be very uncomfortable, it is not serious, and the frequency and severity will decrease as time goes by. If after 4 weeks you are having spasms every time you eat please make an appointment to see us, or at least contact our office by phone or email. Regurgitation during the recovery phase is reflux of fluid within the esophagus, and not from the stomach. It is very unlikely you should need acid-suppressive reflux medications after surgery. If in the future, if someone wants to prescribe reflux medications for you, or you are concerned your reflux is back, please let us know. We strongly recommend a pH test to document reflux prior to starting on reflux medications, especially after surgery. If you are on the go, there are a lot of choices: string cheese, powerbar, dried fruit, trail mix, crackers. Notes: Information on indications for use or diagnosis is assumed to be unavailable.

Maintenance therapy, at recommended daily maintenance doses (Table 2 and Table 4), may be continued indefinitely based on patient need. Therefore, concurrent use of this combination will be reviewed as there is no clinical evidence to suggest that adjunctive administration improves outcome. Only those drug-drug interactions identified as clinical significance level 1 or those considered lifethreatening which have not yet been classified will be reviewed.
