Blood Viscosity
Blood Viscosity samer kareem 1,353 Views • 2 years ago

When the hematocrit rises to 60 or 70%, which it often does in polycythemia, the blood viscosity can become as great as 10 times that of water, and its flow through blood vessels is greatly retarded because of increased resistance to flow. This will lead to decreased oxygen delivery.

Hypertension Urgency
Hypertension Urgency samer kareem 3,103 Views • 2 years ago

Hypertensive emergencies encompass a spectrum of clinical presentations in which uncontrolled blood pressures lead to progressive or impending end-organ dysfunction. In these conditions, the BP should be lowered aggressively over minutes to hours. Neurologic end-organ damage due to uncontrolled BP may include hypertensive encephalopathy, cerebral vascular accident/cerebral infarction, subarachnoid hemorrhage, and/or intracranial hemorrhage.[1] Cardiovascular end-organ damage may include myocardial ischemia/infarction, acute left ventricular dysfunction, acute pulmonary edema, and/or aortic dissection. Other organ systems may also be affected by uncontrolled hypertension, which may lead to acute renal failure/insufficiency, retinopathy, eclampsia, or microangiopathic hemolytic anemia.[1] With the advent of antihypertensives, the incidence of hypertensive emergencies has declined from 7% to approximately 1% of patients with hypertension.[2] In addition, the 1-year survival rate associated with this condition has increased from only 20% (prior to 1950) to a survival rate of more than 90% with appropriate medical treatment

Examination of Peripheral Vascular System - Clinical Skills OSCE Revision - Dr Gill

In this video, we demonstrate the peripheral vascular examination - a less common examination, but still vitally important, particularly amongst the older population

Starting with the examination of the hands looking for clinical signs of vascular compromise, we then check the pulses of the major arteries of the upper body - the radial, brachial and carotid arteries, before moving down to assess for an abdominal aortic aneurysm.

At this point, I feel it's a practical step to check the femoral pulses before doing the overview of the legs.

After visually assessing we must examine the major vascular areas of leg.- namely the popliteal pulses, before wrapping up around the ankle with the posterior tibial and dorsalis pedis pulses

For completeness, the cardiovascular examination is demonstrated here

Anterior Abdomen Wall Abscess
Anterior Abdomen Wall Abscess samer kareem 10,284 Views • 2 years ago

Intra-abdominal abscess continues to be an important and serious problem in surgical practice. Appropriate treatment is often delayed because of the obscure nature of many conditions resulting in abscess formation, which can make diagnosis and localization difficult. Associated pathophysiologic effects may become life threatening or lead to extended periods of morbidity with prolonged hospitalization. Delayed diagnosis and treatment can also lead to increased mortality; therefore, the economic impact of delaying treatment is significant.

Labia minoraplasty is an elective procedure that can reduce the size and reshape the inner vaginal lips. Large or asymmetrical labia minora can leave you feeling self-conscience in tight clothing or during intimacy. Long labia may result in rubbing, irritation or discomfort during intercourse and exercise. Certain skin conditions can cause increased sensitivity or tearing of the labia minora. In some cases, the labia minora may be fused with tissue in the labia majora and require medical correction.

What is Flail chest
What is Flail chest samer kareem 4,799 Views • 2 years ago

A flail chest occurs when a segment of the thoracic cage is separated from the rest of the chest wall. This is usually defined as at least two fractures per rib (producing a free segment), in at least two ribs. A segment of the chest wall that is flail is unable to contribute to lung expansion. Large flail segments will involve a much greater proportion of the chest wall and may extend bilaterally or involve the sternum. In these cases the disruption of normal pulmonary mechanics may be large enough to require mechanical ventilation.

WARNING: Graphic Medical Procedure - Selective Dorsal Rhizotomy Surgery
WARNING: Graphic Medical Procedure - Selective Dorsal Rhizotomy Surgery Surgeon 400 Views • 2 years ago

Dr. Debbie Song at Gillette Children's describes in detail selective rhizotomy surgery.

A selective dorsal rhizotomy is an operation performed to treat spasticity. It is thought that high tone and spasticity arise from abnormal signals that are transmitted through sensory or dorsal nerve roots to the spinal cord. In a selective dorsal rhizotomy we identify and cut portions of the dorsal nerve roots that carry abnormal signals thereby disrupting the mechanisms that lead to spasticity. Potential patients go through a rigorous assessment that includes an in-depth gait and motion analysis as well as a physical therapy evaluation.

They are evaluated by a multidisciplinary team that includes a pediatric rehabilitation doctor, a neurosurgeon, and an orthopedist, Appropriate patient selection is vital. Ideal candidates for selective dorsal rhizotomy are children who are between four and ten years of age, have a history of being born prematurely, and have a diagnosis of diplegia cerebral palsy. These patients usually walk independently or with the assistance of crutches or a walker. They typically function at a level one, two, or three in the gross motor function classification system or gmfcs. A selective dorsal rhizotomy involves the coordinated efforts of the neurosurgery, physiatry, anesthesia and nursing teams. The operation entails making an incision in the lower back that is approximately six to eight inches long. We perform what we call a laminoplasty in which we remove the back part of the spinal elements from the lumbar one or l1 to l5 levels. At the end of the procedure the bone is put back on. We identify and open up the Dural sac that contain the spinal fluid spinal cord and nerve roots. Once the Dural sac is opened ,we expose the lumbar and upper sacral nerve roots that transmit information to and from the muscles of the lower extremities.

At each level we isolate the dorsal nerve root, which in turn is separated into as many as 30 smaller thread light fruitlets.

Each rootlet is then electrically stimulated. Specialized members of the physiatry team look for abnormal responses in the muscles of the legs as each rootless is being stimulated. If an abnormal response is observed then the rootlet is cut.

If a normal response is observed, then the rootlet is not cut. We usually end up cutting approximately 20 to 40 percent of the rootlets. The Dural sac is sutured closed and the l1 through l5 spinal elements are put back into anatomic position, thus restoring normal spinal alignment. The overlying tissues and skin are then closed and the patient is awoken from surgery. The entire operation takes between four and five hours. A crucial component to the success of our rhizotomy program is the extensive rehabilitation course following surgery. With their tone significantly reduced after a rhizotomy, patients relearn how to use their muscles to walk more efficiently through stretching, strengthening, and gait training. Approximately one to two years after a rhizotomy patients undergo repeat gait and motion analysis. The orthopedic surgeons assess the need for interventions to correct bone deformities, muscle contractures, poor motor control, impaired balance, or other problems related to cerebral palsy.

At Gillette we work closely with patients and families to ensure that our selective dorsal rhizotomy program meets their goals for enhancing their function and improving their quality of life.

Inguinal hernia - direct vs indirect, anatomy of inguinal canal, deep ring occlusion test, surgery DrPhil 242 Views • 2 years ago

An inguinal hernia occurs when tissue, such as part of the intestine, protrudes through a weak spot in the abdominal muscles. The resulting bulge can be painful, especially when you cough, bend over or lift a heavy object. However, many hernias do not cause pain.

An inguinal hernia isn't necessarily dangerous. It doesn't improve on its own, however, and can lead to life-threatening complications. Your doctor is likely to recommend surgery to fix an inguinal hernia that's painful or enlarging. Inguinal hernia repair is a common surgical procedure.
