For ear canal stenosis, wide meatoplasty is per as multiple bony lesions and often has long bone formed to restore patency and exteriorize entrapped skin. The active phase of the disease extends Although sarcomatous degeneration is rare for those with into the third and fourth decades. Clinical features that suggest sarcoma be recurrent and results from narrowing of the internal tous degeneration include pain, swelling, and radiographic auditory, and labyrinthine and vertical fallopian canals.

Surgical strategies are chosen by to have the diagnosis of a skull base tumor delayed the skull base surgeon based on approaching the tumor because of an incomplete work-up. By far, the majority with enough exposure to perform a complete and safe of skull base tumors are benign and can be successfully resection while minimizing neurologic morbidity. Tumors of the cerebellopontine angle and Meckel cave are not considered in this chapter General Considerations (see Chapter 61, Nonacoustic Lesions of the Cerebel lopontine Angle). Surgical approaches to these three areas Paragangliomas (or glomus tumors) are tumors of paragan are numerous, and the nomenclature is confusing. To glionic tissue, which originally derive from the migration remove a lesion of the middle ear or mastoid, a mas of neural crest cells during fetal development. These tissue toidectomy through a postauricular incision or a middle rests are distributed predominantly throughout the middle ear exploration through the ear canal is usually adequate. These cell clusters are innervated by toidectomy is performed along with skeletonization of the parasympathetic nervous system and function as the facial nerve, the sigmoid sinus, and the jugular bulb. A well-known, but rare, paraganglioma is the facial nerve out of its bony canal and rerouting it the pheochromocytoma. Permanent facial paresis or synkinesis can there are two main types of paraganglioma: glomus tym occur. Surgical resection of a large jugulotympanic paraganglioma (Fisch Type A approach). Although the classic Fisch Type A approach involves closure of the external auditory canal and rerouting of the facial nerve, these proce dures are not often required to resect even large jugular foramen tumors as shown in this example. Fisch Type B and C approaches (not shown) are not used to approach the jugular foramen, but in stead are used to approach tumors of the in fratemporal fossa, petroclival junction, and na F sopharynx. Good visualiza tion of the petroclival junction, as well as the anterior brainstem, is obtained by this approach. Combined subtemporal Labbe retrolabyrinthine approach for resection of tumors of the petroclival junction. Excellent exposure of the Sigmoid entire brainstem from the posterior circle sinus of Willis to the jugular foramen is obtained. Together these bilateral glomus jugulare tumors and a 7% incidence of nerves are called the tympanic plexus, which consists of an associated carotid body tumor. In addition, another form of the disease has an autosomal dominant mode of transmission, and the Pathogenesis causative genetic defect has been localized to two sepa rate loci: 11q13. Paragangliomas Paragangliomas are also associated with phakoma are slow-growing tumors, and metastases are extremely toses (neurologic diseases with cutaneous manifesta rare.

Indeed, these tumors are highly vas (1) Type A (tumors limited to the middle ear), (2) Type cular and may bleed substantially during surgical excision. If the inner ear is invaded, a senso the classification scheme of Glasscock and Jackson dif rineural hearing loss will be found. Impedance audiome ferentiates between glomus tympanicum and glomus try will reveal a flat tympanogram if a middle ear mass is jugulare tumors. If the tumor is a glomus jugulare tumor that has extended the two most common presenting symptoms of a into the middle ear cavity, this bone will be eroded. In patient with a paraganglioma of the temporal bone are contrast, if the tumor is a glomus tympanicum tumor, conductive hearing loss and pulsatile tinnitus. There may be a semicircular canal fistula or the symptoms of sympathetic discharge, which may repre tumor may be in close proximity to the fallopian canal, sent a functionally secreting tumor, such as tachycardia, particularly along the vertical segment. Moreover, extend anterior to the internal auditory canal or along the patient should be queried about any symptoms of the petrous portion of the internal carotid artery. These dysphagia or hoarseness, which may represent palsy of findings may affect the planned surgical approach.

Tricuspid and Doppler imaging better define the mechanisms responsible regurgitation can be due to rheumatic valvulopathy, infec for regurgitation. It is then possible to tailor valve repair to cor tious endocarditis, Carcinoid syndrome, rheumatoid arthritis, rect the anomaly and optimize results (3,5). In patients with atrial flutter, cyroablation caused by infective endocarditis alone and very rarely by of the inferior vena cava-right atrial junction may ablate the Carcinoid syndrome. It appears to improve the repair rate, survival (where a ratio of one to three is mild, a ratio of two to three is and freedom from reoperation (11-13). Supraventricular criticism because the dimension of the regurgitant jet is influ arrhythmia appears to be better tolerated and responds more enced by many factors including echogenicity of the patient, readily to pharmacological treatment (15). In the presence of a the hemodynamic state and the direction of the regurgitant jet right to left shunt, a more aggressive surgical approach should (3,4). Valve replacement is only performed in the context of a Moderate tricuspid regurgitation repaired at the time of failed repair or a population subset with more dysmorphic fea mitral intervention has an unclear prognosis (16,25); however, tures not amenable to repair (8-14). Other tricuspid lesions: Management of tricuspid regurgita Tricuspid valve procedures at the time of mitral surgery have tion due to organic disease must be tailored to the disease been the subject of debate. The repair should correct anomalies of the different varying degrees with a decrease in pulmonary hypertension components of the valve (18). The resolution of severe tricuspid regurgitation including the implantation of polytetrafluoropropylene chordae in this context cannot always be accurately predicted and can (30). The depend on several factors including the following: valve can be converted into a bileaflet valve with resection of 1. Quality of the left-sided repair or replacement and, therefore, vegetations and the infected valve leaflets. The outcome of patients with functional tricuspid regurgi Choice of repair technique: Annular dilation is the most fre tation that was not addressed during repair of left-sided valvu quent cause of tricuspid regurgitation. It can be addressed by lopathy varies between studies because of differences in patient annuloplasty with a prosthetic ring (eg, Carpentier, Duran and selection and criteria for defining the severity of tricuspid Cosgrove rings), prosthetic bands or without a synthetic ring regurgitation, and inconsistent use of intraoperative assess (eg, De Vega and Kay-Boyd annuloplasties). All of these techniques, however, were equally 35% of patients with severe functional tricuspid regurgitation efficient for moderate tricuspid regurgitation due to isolated not addressed at initial mitral valve surgery must undergo tricuspid dilation (39-41). In Choice of prosthesis: the best type of prosthesis for tricuspid addition, reoperations for residual tricuspid regurgitation replacement is a topic of ongoing debate. Porcine and bovine have a high mortality rate, ranging between 14% and 27% pericardial bioprostheses tend to be favoured due to their low (22-24). Porcine bio patients with functional tricuspid regurgitation is reported to be prostheses appear to be more durable in the tricuspid position less than that for a combined mitral and tricuspid operation compared with the mitral position, even in children. In young patients with isolated tricus eration of bileaflet mechanical prostheses appear to offer better pid valve disease or already on an anticoagulation regime, performance than older generations (22,43).

Diagnosis: Echocardiographic evidence of dysplastic obstruc Aortic regurgitation tive aortic valve is diagnostic. Neonates may be dependent on a patent ductus young adults with a bicuspid aortic valve, discrete subaortic arteriosus for systemic perfusion. Aortic regurgitation may occur following either same pathophysiology as in the adult, except that because of balloon valvotomy or surgical valvuloplasty, after attempts to rapid patient growth, the obstruction can progress rapidly with relieve aortic stenosis. In some cases, fibroelastosis of dilation may occur following complete repair of pulmonary the endocardium can be seen on echocardiogram. Recent data in adults suggest that an ejection fraction balloon valvotomy and, if unavailable, open aortic valvulo less than 55% is associated with higher mortality postopera plasty is a reasonable alternative (12-17). To preserve long term cardiac function in children, Special considerations: the spectrum of the hypoplastic left even a lower threshold might have to be used. Exercise testing heart syndrome (aortic hypoplasia, mitral stenosis and small left should be done periodically in these patients and decreasing ventricle) overlaps with critical neonatal aortic stenosis. These exercise tolerance should be regarded as an indication for valve infants may require a univentricular approach.

In addition, mechanical pros Mitral stenosis theses can have a high reoperative rate, usually secondary to Etiology: In developed countries, mitral stenosis, like mitral nonstructural dysfunction due to subvalvular pannus and regurgitation, is the result of a wide spectrum of morphologi hemolysis from paravalvular leak (29).

Due to the frequent asso to commissure papillary muscle fusion, short chordae, with ciation of atrial septal defect and mitral stenosis, transmitral abnormal papillary muscle and parachute mitral valve, ham gradient should not be the only criteria used to define the mock mitral valve and papillary muscle hypoplasia. However, many infants with congenital mitral stenosis Pathophysiology: Similar to mitral regurgitation in adults. Valve repair should be the preferred an uncommon valvular entity characterized by a wide spectrum option in small children even if the result is suboptimal. The artificial chordae can delay or possibly Indications for intervention: the procedure of choice is percu prevent the need for mechanical prostheses (38). Mechanical taneous balloon valvotomy for symptomatic patients or those prostheses may require replacement in a growing child; a larger with high right ventricle to pulmonary artery peak gradients prosthesis can be implanted because the mitral valve annulus can (48-50). The reduction in gradient and survival is similar with grow even when fixed to a prosthetic sewing ring.

Natural history: the mode of presentation is either in the Good results have also been reported with balloon valvotomy newborn period with symptomatic critical pulmonary stenosis in adults. Infants need close follow-up following dilation or later when an asymptomatic patient is referred for murmur because reintervention is needed in 12% to 25% of patients in evaluation (46). The Natural moderate regurgitation can be associated with an abnormal History of Congenital Heart Defects study (10,47) revealed appearing bicuspid pulmonary valve with elongated leaflets that the 25-year survival rate (greater than 95%) was compa and no evidence of pulmonary stenosis.

Abdominal aortic ultrasound may reveal a distal thoracic aortic dissection that extends below the diaphragm 6 mp treatment discount 25 mg strattera, and in the hands of skilled sonog raphers has been shown to be 98% sensitive. Scanning should continue down the vein through the confluence with the saphenous vein to the bifurcation of the vessel into the deep and superficial femoral veins. The popliteal vein, the continuation of the superficial femoral vein, can be examined from high in the popliteal fossa down to trifurcation into the calf veins. If an upper extremity thrombus is clinically suspected, the same compression techniques can be employed, following the arm veins up to the axillary vein and into the subclavian vein. Although a good initial test, the sensitivity of ultrasound for proximal upper extremity clots is lower than for lower extremity clots, as the subclavian vein cannot be fully compressed behind the clavicle. The initial imaging focus of ultrasound as used by Radiologists was on anatomy and pathology. Now with clini cians actively using this technology at the bedside, attention has shifted to the crucial evaluation of physiology. The ability to recognize both abnormal pathology and phys iology in a critical patient, recognize a distinctive shock state, and arrive at a more precise diagnosis represents a new paradigm in resuscitation care. Clinicians around the world are recognizing the power of point of care ultrasound and the impact it will have on critical care resuscitation in the Emergency Department, as well as in Inten sive Care Units.

It is anticipated that this Cardiothoracic Orientation Package will: Provide a stimulating and meaningful experience that builds upon the nurses existing knowledge base Utilise research findings to improve patient care; Utilise innovative teaching/learning approaches; Integrate new theoretical concepts with current practises and be An open, honest, pragmatic and collaborative learning package. The care of the critically ill patient involves not only what the nurse does but most importantly what the nurse sees, hears and feels. With these combinations, antecedents to life threatening conditions are recognised early, prevented and/or managed. With initiative and an introductory orientation package to cardiothoracic intensive care, any capable nurse can attain additional knowledge, skills and attitude needed for competence in cardiothoracic intensive care nursing. It is anticipated that it shall take the orientee/staff member three to six months to become competent depending on the individual needs, prior intensive care nursing experience and the completion of the allocated worksheets within the package. Preceptors who have experience in the field of Cardiothoracic shall support these staff members. The Cardiothoracic Clinical Nurse Educator and the Unit Manager are responsible for the overall coordination and facilitation of the package. Resource materials such as appropriate literatures, simulated practice, and worksheets will be made available to encourage self direction. The participants will be required to complete the worksheets that are included in the orientation package and a pulmonary artery catheter competency. The participants will spend one morning observing a patient undergoing coronary artery bypass graft surgery and/or valve surgery in the operating theatre (This will depend on staff numbers for the day) this will help the orientee to fully understand the anatomical difficulties the surgeon faces, the role of the bypass machine in respect to the heart and lungs and why potential complications may occur. The blood vessels form a network of tubes that carry the blood from the heart to the tissues of the body and then return it to the heart. The fibrous layer is the outer layer and is attached to large blood vessels entering and leaving the heart. It is also attached to the diaphragm and to the inside of the sternal wall of the thorax. It is attached to the parietal pleura which prevent the heart from over distending. It is continuous with the visceral pericardium at the base of the heart and around the large blood vessels. Epicardium ~ Thin transparent outer layer of the wall ~ composed of serous tissue and mesothelium ~ Pericardial sac is between epicardium and pericardium which contains a watery fluid known as pericardial fluid which prevents friction between the membranes as the heart moves 2. Myocardium ~ Middle layer of the heart ~ It is the cardiac muscle tissue which is responsible for the contraction of the heart ~ the muscle fibres are involuntary, and the tissue is arranged in interlacing bundles of fibres 3. Endocardium ~ Is the inner layer of the heart ~ It is a thin layer of endothelium overlying a thin layer of connective tissue pierced by tiny blood vessels and bundles of smooth muscle ~ lines the inside of the myocardium and covers the valves of the heart and tendons that hold them open. Chambers of the heart the heart has four chambers Right and Left Atrium ~ Are the smaller upper chambers of the heart ~ the left atrium receives blood from the lungs ~ the right atrium receives blood from the rest of the body ~ the atrium allows approx 75% of blood flow directly from the atria into the ventricles prior to the atria contracting. Atrial contraction then adds 25% of filling to the ventricles; this is referred to as atrial kick. Atrioventricular Valves are the valves that lie between the atria and the ventricles. There are 2: i) Tricuspid Valve ~ Is between the right atrium and the right ventricle ~ Consists of three flaps or cusps which are fibrous tissue ~ Chordae Tendinae are tiny collagen cords that anchor cusps of the valve to papillary muscle ii) Mitral Valve ~ Lies between the left atrium and left ventricle ~ Consists of two cusps Semilunar Valves are the two valves located between the pulmonary artery and the aorta that prevent blood from flowing back into the heart. Both parasympathetic and sympathetic parts of the autonomic system are involved in the control of the heart. The chambers and walls of the heart can go on contacting and relaxing without any direct stimulus from the nervous system. This is possible as the heart has its own regulating system called the conduction system. This cycle can be broken up into three phases; Atrial systole, Ventricular systole and Ventricular filling. However, in mid diastole the valves move toward the closed position and then open again widely during atrial systole. End-Diastolic Volume, End-Systolic Volume and Stroke Volume Output ~ End Diastolic volume is the filling in each ventricle (110-120mL) at the end of diastole.
