Scattered Radiation Levels and Radiation Protection For radiation safety reasons, it is important to assess the scattered radiation levels in the procedure room, the x-ray control booth, and the adjacent external spaces into which the staff or general public can have access. There are regulatory limits for the amount of radiation to which the staff and general public can be exposed. Furthermore, knowledge of these radiation levels permits the staff to try to limit the radiation expo sure by procedural methods or by appropriate radiation shielding devices. To measure the scattered radiation levels, a large amount of attenuation mate rial (20 to 25 cm of acrylic or 25 to 30 cm of water) is placed in the x-ray beam to simulate a large patient. A radiation survey instrument with a flat energy response in the diagnostic x-ray range, and a radiation exposure sensitivity range of 1 µR per hour to 10 R per hour is used to measure the scattered radiation. The scattered radiation levels are measured using typical clinical settings inside the procedure room, in the x-ray control booth, and in adjacent areas. From the measurements and the workloads, the weekly estimated radiation levels at various locations can be calculated and compared to regulatory limits. Moreover, the effectiveness of various radiation barriers (suspended face radiation shields and/or portable floor radiation shields) can be determined (Balter et al. The estimated radiation levels in the x-ray control booth should be less than 1 milliSievert per week. In adjacent external spaces which are designated “non controlled” access areas, the estimated weekly levels from scattered radiation should be less than 0. Scattered radiation levels inside the procedure room at locations where the physicians may stand can be 1 to 4 milliSieverts per hour (unless protective barriers are employed). The evaluations should yield scattered radiation levels less that these and within regulatory limits. Clinical Radiation Exposure Monitors Some newer cardiac imaging systems are delivered with integrated real time clinical radiation exposure monitors. These monitors record the amount of ioniz ing energy delivered to the patient during clinical procedures. As an alternative, one company provides a system which calculates the entrance skin exposure corrected for table attenuation and changes in the distance from the focal spot to skin entrance plane (Strauss 1995). Regardless of the type of information collected, an automated database networked to the system is necessary for managing patient dose data. If data related to the patient radiation exposure or dose are provided by the machine, the accuracy of the device’s calibration should be checked by the physicist at least annually. Electrical and Mechanical Safety Because of the danger to the patient from small electrical leakage currents that could potentially affect the heart during cardiac catheterization, it is important to assess the electrical ground and electrical leakage current of all components and the patient table (Strauss et al. In addition, all electrical outlets and emer gency power for the room should be thoroughly checked. At most large facili ties, these measurements are usually performed by the Biomedical Engineering personnel; sometimes the equipment manufacturer’s installers will also perform these electrical safety tests. Any imaging equipment with powered, moving components some distance above the floor present potential mechanical hazards to the patient and the oper ator. Special attention must be given to any ceiling suspended components; any weight bearing bolts and nuts must be checked for tightness periodically (Strauss et al. While all these necessary mechanical inspections and adjustments are typically performed by the equipment manufacturer as part of a comprehensive service contract, the responsible physi cist should be reviewing the vendor’s programs and reports to ensure patient and personnel safety. Other Checklist Items There are a number of items that should be evaluated to make certain they are present and functioning effectively. There is a regulatory requirement that all flu oroscopic units have a “5 minute timer” which either sounds an audible signal or stops x-ray production at the end of each 5 minutes of actual fluoroscopy time. The purpose of this regulation is to remind the physicians performing the clinical procedures of the radiation dose being delivered to the patients. It is also impor tant that an intercom system be installed so that the physicians in the procedure room can communicate effectively with the technologists operating the x-ray 40 equipment and electrophysiology equipment. The x-ray tube potential and tube current should be continuously dis played during exposures. The display monitors should be free of artifacts and non-uniformities; their contrast and brightness levels should be adjusted to optimize the clinical images. These display monitors should be tested periodically and receive periodic maintenance (Roehrig et al. Emergency electrical receptacles should have power for potential use of defibrillators. There should not be any sharp edges or obstructions on any of the equipment in the room that could cause potential injury to patients and staff. The rooms should be properly marked with signs on the out side to indicate that they are x-ray procedure rooms. There should be adequate protective apparel for the staff, and it should be checked at least annually for holes, cracks, or other voids. All staff should be issued and should wear radiation badge monitors when working in and around cardiac cath facilities. Overview of Clinical Cardiac Procedures Clinical cardiac procedures basically fall into two categories: diagnostic and interventional. Cardiac catheterization is a diagnostic procedure which involves the insertion of catheters into either the femoral (most common) or brachial arter ies which lead to the heart. The catheters are used to deliver contrast material either to the coronary arteries or the left ventricle in order to increase their opacification to x-ray transmission. In this fashion, the vessels can be clearly seen during angio graphic x-ray imaging, and the left ventricle’s ability to contract and pump blood can be analyzed. Many of the studies are directed toward evaluation of stenoses in the coronary vessels either due to degenerative disease or thrombosis. Ventriculography is utilized to evaluate wall motion, septal perforation and mitral insufficiency (Wexler 1995; Pepine et al. The angiographic procedure is deemed successful when a >20% increase in the diameter of the vessel lumen has been achieved and the stenosis represents less than a 50% occlusion of the 41 vessel. The source is removed after delivering a high radiation dose to the vessel walls; the irradiation of the vessel walls is thought to help prevent future restenosis. There is also a Rotational Atherectomy in which a high speed rotational drill selectively grinds the plaque material into fine particles opening the vessel (Roto-Rooter procedure). Most stents are self-expanding stainless steel or tantalum alloy coils of wire which act as a structural support to the vessels. Published Radiation Doses from Fluoroscopy and Cine Imaging With the rapid development of the methods and technology available to the interventional cardiologist, assessments of radiation dose and relative risks are not available for all of the procedures mentioned above. In the late 1970s, when cineangiographic procedures were used almost exclu sively, the cardiac fluoroscopy times were approximately 20 min with associated entrance skin exposures ranging from 10 to 60 R (Reuter 1978). Cine exposures of 2 to 3 min might contribute an additional 2 to 9 R of entrance exposure. In the 1980s improvements in technique and equipment reduced diagnostic angiographic fluoroscopy time to about 4 minutes, with only about 60 sec of cineangiography time (Finci et al. These more complicated procedures typically led to more cineangiography runs with continuous fluoroscopy during balloon inflation. Commonly 17 min of fluo roscopy and 30 sec of cineangiography are added for a single-vessel procedure or 42 20 min of fluoroscopy and 50 sec of cineangiography may be added for a double vessel procedure (Finci et al. It is common practice for 2000 or more cineradiographic frames to be acquired per coronary angioplasty procedure (Pattee et al. Five percent or more of patients submit to angioplasty procedures three or more times, resulting in average total entrance skin doses of about 5 Gray (Pattee et al. First the occlusion must be crossed with a guide wire without piercing the vessel and then one or more balloons serially inflated. These investigators found that angioplasty of a totally occluded artery results in exposure times and entrance skin doses which are about 50% greater (31 min, 0. Entrance doses resulting from cine angiography for angioplasty procedures on total stenoses ranged from 0.
The scienti c activity has increased signi cantly medications descriptions best 50 mg cytoxan, and is nowadays well-funded and even the youngest colleagues can be nancially sup ported treatment mastitis proven cytoxan 50mg. The visibility of the Department and its chairman in the Finnish society and the inter national neurosurgical community has de nitely brought support along with it medicine 94 generic cytoxan 50 mg amex. Overall medicine list cheap cytoxan american express, the changes during the past two dec ades have been so immense that they seem almost di¬cult to believe. If there is a lesson to be learned, it could be this: with su¬cient dedication and endurance in the face of resist ance, almost everything is possible. If you truly believe the change you are trying to make is for the better, you should stick to it no matter what, and it will happen.

The department, managed by Professor and Chairman Juha Hernesniemi and Nurse Man ager Ritva Salmenpera (Figure 2-4), belongs administratively to Head and Neck Surgery, which is a part of the operative administrative section of Helsinki University Central Hospital. As a university hospital department, it is the only neurosurgical unit providing neurosurgical Figure 2-4. Nurse Manager Ritva Salmenpera treatment and care for over 2 million people in the Helsinki metropolitan area and surrounding Southern and Southeastern Finland. Because of population responsibility, there is practically no selection bias for treated neurosurgical cases and patients remain in follow-up for decades. These two facts have helped to create some of the most cited epidemiological follow-up stud ies. In addition to operations and in patient care, the department has an outpatient clinic with two or three neurosurgeons seeing daily patients coming for follow-up check-ups or consultations, with approximately 7000 vis its per year.

Neuroradiologists A dedicated team of ve neuroradiologists and one or two residents or younger colleagues is lead by Associate Professor Marko Kangasnie mi. Endovascular procedures are carried out in a dedicated angio suite by neuro radiologists in close collaboration with neuro surgeons. Bed wards the department of neurosurgery has a total of the sta© at bed wards consists of one head 50 beds in two wards. Of the 50 beds, seven are nurse at each ward, nursing sta© of 45 nurses intermediate care beds and 43 unmonitored and 3 secretaries. They also take care of medication, nu Patients coming for minor operations, for ex trition and electrolyte balance, interview pa ample spinal surgery, usually spend relatively tients for health history, perform wound care short time on the ward, 1-2 days after opera and stitch removal, give information and home tion before being discharged. Patients can have problems with breath ing, still need respiratory care, have problems with nutrition, anxiety and pain; all this care is given by our sta© nurses. When needed, the nurses alert also neurosurgeons and anesthesi ologists based on their observations. The nurses in the two wards rotate in intermediate care room so that everyone is able to take care of all critically ill patients. Nurses also take care of pain and anxiety two isolation rooms for severe infections, or relief. Neurosurgeons make the majority of the patients coming for treatment from outside of decisions concerning patient care, discuss with Scandinavia (to prevent spread of multiresist the patient and family members, make notes to ent micro-organisms).

Intensive care tious diseases and orthopedic, maxillofacial nurses take care of patient monitoring and do and plastic surgery. This principle of electronic patient les and computerized data planning the working hours is the same in all collection. Critically ill patients, organ donors and small children are allocated to nurses only after he or she has su¬cient experience in common proce dures and protocols. The last step after two or three years of experience is to work as a team leader during the shift, i. Mika Niemela (standing in the back), head nurse Saara Vierula (front row, rst from right) and head nurse Marjatta Vasama (front row, fourth from right). The tasks of scrub nurses include patient safely and individually, even though emergency positioning (done together with technicians, situations may require such rapid thinking and the neurosurgeon and the anesthesiologist), decision-making that things may almost ap the skin preparation, draping, instrumentation, pear to happen by themselves. Nurses are divided patients to neuroradiological examinations and into two groups: scrub nurses and neuroan interventions and take care of and monitor pa esthesiological nurses. Because almost half of our pa After a couple of years of concentrating ei tients are emergency patients, the active work ther on anesthesia or instrumentation we try ing hours for those on call usually continues to encourage the nurses, who are interested until midnight or later, and the next day is free. We hope that both whole sta© gets their paychecks, needs of for students and our nurses approach neurosurgical eign visitors are accommodated, Prof. This can result in a high level of up-to-date despite last minute changes of an satisfaction and more options for professional extremely busy schedule In other words, this advancement. This gives quired to keep the wheels of the Department an opportunity to do national and international lubricated – unless there would be a glitch and co-operation and gives possibilities to attend nothing would work anymore! The whole complex was refurbished in 2005 according to the needs of modern microneurosurgery, with emphasis on e¬cient work ow, open and inviting atmos phere, and teaching with high quality audio visual equipment. The advantage of us ing the same room is the avoidance of patient transfer and the inherent risks associated with this. The disadvantage is that the room has to have the appropriate space, storage, equip ment, and ambience for both functions. In our experience, the time that is saved by having a separate anesthetic room is very limited com pared to the length of the actual procedure, transferring the patient and the time spent re connecting all the necessary cables and lines. After trying both options, we have settled for handling the whole anesthesia and patient po sitioning inside the operating room. The reasons seem to be the following: spect between all members in the team is a key factor in creating a successful ambience. The We also feel that it is a great asset that the surgeon habitually and genuinely thanks nurses are dedicated to and very experienced the theatre sta, especially after a di§cult in neurosurgical operations – often the cor or long case.

Come off bypass and decannulate aorta with purse strings being tied (aortic line may be clamped or not depending on centers procedure) symptoms 0f high blood pressure cytoxan 50mg sale. Resident should be given the opportunity to medicine 0552 buy discount cytoxan practice during the week after the session using the HeartCase or some equivalent simulation model or by having access to medicine 3605 purchase cytoxan 50mg fast delivery the Aortic Cannulation Simulation model in the simulation center treatment jock itch buy cytoxan 50mg cheap. Although not an inherent part of this session, bicaval cannulation can be discussed and demonstrated. The resident will also be trained in administering antegrade and retrograde cardioplegia. The simulation uses a beating heart model (Ramphal Cardiac Surgery Simulator) for placement of the venous cannula, ascending aorta antegrade cardioplegia cannula, aortic cross clamping, and right atrial coronary sinus retrograde cardioplegia cannula placement (minimum of 7 repetitions for each) the first 3 repetitions should be done on each of the 2 tasks separately (venous cannulation and antegrade catheter placement with aortic cross clamping, while the last 4 repetitions should be done with both in sequence. Because of limited space on the right atrium, all purse strings will not be required to be in the optimal position. Able to cannulate the aorta, showing mastery of pursestring placement, securing, and de-airing cannula. Able to place right atrial pursestring and retrograde cardioplegia cannula into coronary sinus, order retrograde cardioplegia, and remove cannula and secure right atrial pursestring. Each resident will perform venous cannulations, antegrade, and retrograde cardioplegia until error-free, using the pressurized pig heart. The cannulation and de-cannulation and cardioplegia technique practiced will be specific to the training center. The simulation will provide better training if the resident is gowned, gloved, and masked during the session. During the venous cannulation simulation, the resident will be expected to perform the parts of the 7 steps appropriate to venous cannulation. The resident will place a purse-string suture into the right atrium wall and place it through a tourniquet slider and clamp it. The resident will insure the correct cannula is available, incise the atrium through the purse string, and place the cannula into the atrium. Resident will assess the heart for placement of the cardioplegia line in the aorta and place the appropriate purse string. Resident will insure the correct aortic cardioplegia cannula is available and place the cannula into the aorta. The resident places the purse string in the atrium for the retrograde cardioplegia line. The retrograde cannula is placed into the coronary sinus through the atrial purse string. If it is not possible t thread the catheter into the coronary sinus, the resident should position it as close as possible to the coronary sinus. The resident assures the proper conditions for cross clamping the aorta and then cross clamps the aorta. The resident instructs the perfusionist to give the appropriate amount of antegrade and retrograde cardioplegia. The different amount for different procedures should be gone over with the resident. The resident assures proper conditions for cessation of cardioplegia (temperature) and releases the cross clamp. The aortic cardioplegia and coronary sinus cannulas are removed and the purse strings secured. The resident will conduct an informed, efficient, and technically expert cardiopulmonary bypass run including all cannulation steps, appropriate commands, and understanding of critical elements within 30 minutes 3. Extra practice on component parts in which the resident is found to be deficient should be performed to achieve proficiency 4. Residents should perform the complete procedure as both surgeon and assistant until error-free. Emphasis is placed on techniques of coronary artery anastomosis including instrument use and tissue handling. Teaching and practice are based on orientation and feedback using component task simulators and the high-fidelity Ramphal Cardiac Surgery Simulator. The component task approach to cardiac surgery training in the dry-lab and wet-lab settings provides initial training and a basis for ongoing deliberate practice. Competence in performing anastomosis on small vessels requires extensive and deliberate practice. The goal of the session is to understand and demonstrate proficiency in basic skills, such as the ability to perform distal and proximal coronary artery anastomosis. Integral to the procedure is understanding instrument use, suture management, and tissue handling. Synthetic graft material will be used from the Chamberlain Group or from LifeLike. Perform distal and proximal end-to-side anastomosis using the HeartCase or equivalent simulators and porcine heart model. Perform distal end-to-side anastomosis (left anterior descending artery, obtuse marginal artery and posterior descending artery) and proximal aorto-coronary anastomosis using the Ramphal Cardiac Surgery Simulator. Learn how to find, select and open the artery for the distal anastomosis and perform a small aortotomy for the proximal anastomosis. Determine the approximate length of the graft and orient the graft for the proximal anastomosis using the porcine model and the Ramphal simulator. Practice at home using the HeartCase or equivalent simulator and log the practice time. If desired, tissue models (porcine heart, CryoVein) can be used for the simulation and homework sessions instead of synthetic models and conduits. Likewise, the resident is encouraged to provide feedback regarding the perceived relevance of the assignments and the validity of the tasks. For instance, feedback may include perceived value of the tasks, difficulty of the tasks, perceived improvement and progress, and level of comfort performing the procedures. Identify 3 coronary lesions seen on angiogram and describe the appropriate bypass strategy 4. The first supervised anastomosis (which would be the second one done) can also be video recorded for documentation. End-to-side anastomosis overview: Simulation of the end-to-side anastomosis is performed using a synthetic conduit, such as Chamberlain or Lifelike graft and target vessels, and synthetic or 27 porcine aorta to simulate proximal anastomosis. Using synthetic or porcine aorta, make a small aortotomy with a knife (#11 blade) and enlarge with an aortic punch (3-4mm). Perform using the synthetic graft vessel (3mm) with 5-0 polypropylene sutures (or institutional preference). Aortic graft (Chamberlain Group) 28 For the distal anastomosis: Steps: Make arteriotomy. Using synthetic target vessel (3-4mm), make a small arteriotomy and extend with scissors. Perform using the synthetic vessel (3mm) with 6-0 polypropylene sutures (or institutional preference). Residents should perform the proximal anastomosis and the distal anastomosis at least 5 times at this session. Extra practice is on component parts in which the resident is deficient should be carried out to achieve proficiency. Porcine hearts placed in the wet-lab container are used for training in distal end-to-side anastomosis. Important components include arteriotomy and aortotomy, measuring length of graft, technical challenges with anastomosis, and briefing/debriefing (feedback). Homework assigned will be proximal and distal anastomosis (HeartCase/equivalent) and optional sim lab with porcine heart model. Prerequisites Each resident will have performed at least 10 vessel anastomosis using the HeartCase/equivalent since the last session as homework. The actual requirements should be tailored to the technical skill needs of the individual resident Objectives 1. The instructor may want to open the anastomoses and evaluate their quality with the resident. If this is not the case, either more homework or more time in this session should be encouraged. Porcine heart model (porcine heart in wet-lab container) Achieve adequate exposure 1.

Post-ictal psychiatric disturbances are more likely to occur following clusters of seizures, generalised 14. These episodes are usually brief and common after complex partial or generalised the prevalence of this is low (<5%) and characterised by periods of depressed mood and episodes of tonic-clonic seizures. Aggressive behaviour may occur and is usually undirected or resistive and the mania. Several case series have reported a preponderance of patients with complex partial epilepsy, patient is likely to be amnesic for the event. Post-ictal depression can last longer Inter-ictal psychosis (up to two weeks) than other post-ictal states. Symptoms range from mild to severe and may involve the prevalence is reported to be 4-10% in patients with epilepsy, mainly in those with temporal lobe suicidal behaviour. It has been reported to occur more commonly with right-sided temporal or frontal epilepsy7,8,9. It is a chronic disorder and clinically resembles chronic schizophrenia (symptoms of foci2. There are a few case reports of post-ictal mania delusions, hallucinations, thought disorder) but there are some reports that personality is better preserved. The risk factors that have been reported are early age of onset of epilepsy, bilateral temporal foci and a refractory course. The Post-ictal psychosis pathophysiological mechanisms of psychosis in epilepsy are unclear and both focal and generalised brain the prevalence has been estimated to be 6-10% in patients with epilepsy, particularly temporal lobe abnormalities have been implicated12–15. It typically occurs after a cluster of complex partial seizures (+/ secondary generalisation). There is usually a period of lucidity (12-72 hours) prior to the onset of psychosis. The psychotic symptoms Treatment with antipsychotic medications is usually long term. The atypical antipsychotic drugs are include delusions, hallucinations, thought disorder or mania, which are usually transient but can last potentially less likely to reduce seizure threshold (with the exception of clozapine) or cause extrapyramidal several weeks. It has also been reported that some patients with recurrent episodes of post-ictal psychosis side effects. Predisposing risk factors are ictal fear, bilateral epileptic foci or support and family education are also important. Mechanisms are unknown but may be related to transient neurochemical changes as a result of seizures. Treatment-related psychiatric problems Treatment of acute post-ictal psychosis may require short courses of benzodiazepines or antipsychotics. Phenobarbitone, primidone, tiagabine, Inter-ictal topiramate, vigabatrin and felbamate have been associated with depression. Depression Research has shown that nearly 40% of patients studied in tertiary epilepsy centres had major depression Improved seizure control has been associated with the emergence of psychiatric symptoms. The true prevalence of depression introduced the term ‘forced normalisation’ which refers to a dramatic reduction in epileptiform activity in epileptic patients in the community has not been established. The risk may be higher in patients who are on polytherapy, become seizure However, it is important to recognise that some patients can present with atypical depressive symptoms, free abruptly, or if there is a past psychiatric history. This is characterised by chronic intermittent dysthymia, irritability and anxiety symptoms. Epilepsy surgery Transient mood disturbances (emotional lability, depression and anxiety) have been reported following Treatment for depression includes psychological interventions such as counselling, psychotherapy or temporal lobe surgery for epilepsy (about 25%) in the first 6-12 weeks16. For moderate to severe depression, antidepressant medications (10%), symptoms, particularly depression, may persist and require psychiatric treatment.

Nevertheless, the diagnosis of epilepsy is frequently straightforward, particularly when precise and detailed personal and eyewitness accounts of the prodrome, onset, evolution and recovery period after the event are obtained. Misdiagnosis is common, however, and possibly affects up to 2-30% of adults with a diagnosis of epilepsy1,2. This and other reports highlight the high rate of misdiagnosis of epilepsy, the cause of which is undoubtedly multifactorial. The reasons for misdiagnosis may include a deficiency of relevant semiological information obtained during the ascertainment of the clinical history, lack of understanding of the significance of specific clinical features and over-reliance on the diagnostic value of routine investigations4. The attainment of a correct diagnosis is of paramount importance as an erroneous diagnosis of epilepsy has physical, psychosocial5 and socioeconomic consequences for the patient, and economic implications for the health and welfare services6. Syncope Transient loss of awareness is common, and may affect up to 50% of people at some stage of life7,8,9. Elucidating the aetiological basis for an episode of loss of awareness is challenging. Typically, the episode is transient, patients are generally unable to provide an accurate description of the event and there may be a lack of reliable witnesses, particularly in the elderly who, more frequently, live alone. The difficulty in establishing an accurate diagnosis is further hampered by systemic and neurological examinations and subsequent investigations frequently being normal after an episode or between habitual attacks when the patient is seen in the hospital ward or clinic10. Orthostatic syncope is caused by autonomic failure rather than an exaggerated and inappropriate but Syncope is more prevalent than either epilepsy or dissociative (psychogenic) seizures and is common essentially normal physiological response, as seen in neurocardiogenic syncope. Vasovagal syncope is vasoconstrictor response to standing, resulting in venous pooling and a postural fall in blood pressure, most frequently encountered in adolescence, whereas syncope due to cardiac causes becomes increasingly usually within seconds or minutes of becoming upright. The annual incidence of syncope in the elderly population in long-term stays warm and well perfused, the pulse rate is unchanged and sweating is absent. Recurrence is not unusual, occurring in approximately dysfunction are varied and include autonomic neuropathy due to diabetes, alcohol, amyloidosis, genetic 30% of patients, typically within the first two years after symptom onset13. Recurrence is associated abnormalities or complex autonomic failure, such as primary autonomic failure or multiple system with increased morbidity, such as fractures, subdural haematomas and soft-tissue injuries14, and impaired atrophy.
