Both lower extremities must be evaluated to determine the presence or extent of any disease and to ascertain the pulse status of the patient. The feet are examined for signs of peripheral vascular disease and the anterior and posterior tibial pulses are palpated. Because an intact arch can supply retrograde flow to the major vessels of the foot, it can be helpful to put pressure on the anterior tibial artery when detecting the presence of a posterior tibial pulse and visa-versa. This "modified Allen's test" may detect proximal vessel obstruction masked by an intact foot arch. The need for preoperative angiography in young, healthy patients with a normal physical examination has been hotly debated. Our tendency has been to obtain preoperative angiograms as a guide. Although rare, we have seen lower extremities with a dominant peroneal artery nourishing the foot and distal anterior and posterior vessels, contraindicating sacrifice of the peroneal artery. MRI or CT angiography can also be used in many circumstances.
What is a brain aneurysm? A brain (cerebral) aneurysm is a bulging, weak area in the wall of an artery that supplies blood to the brain. In most cases, a brain aneurysm causes no symptoms and goes unnoticed. In rare cases, the brain aneurysm ruptures, releasing blood into the skull and causing a stroke. When a brain aneurysm ruptures, the result is called a subarachnoid hemorrhage. Depending on the severity of the hemorrhage, brain damage or death may result.
Devi Shetty, founder of Narayana Health in India, reflects on the remarkable fact that, after 26 years of operation, the cost of heart surgery at Narayana Health has come down dramatically, and shares some of the strategies used to maintain high quality with low patient cost.

To understand congenital heart defects, it's helpful to know how a healthy heart works. Your child's heart is a muscle about the size of his or her fist. The heart works like a pump and beats 100,000 times a day. The heart has two sides, separated by an inner wall called the septum. The right side of the heart pumps blood to the lungs to pick up oxygen. The left side of the heart receives the oxygen-rich blood from the lungs and pumps it to the body. The heart has four chambers and four valves and is connected to various blood vessels. Veins are blood vessels that carry blood from the body to the heart. Arteries are blood vessels that carry blood away from the heart to the body.
The thyroid gland lies in the midline of the anterior neck, just caudal to the thyroid cartilage. To inspect the thyroid gland, the examiner stands in front of the patient. The examiner asks the seated patient to dorsiflex (extend) the neck and swallow a sip of water. Minor enlargement of the gland may only become apparent on inspection in this position. Palpation of the thyroid gland is typically performed with the examiner standing behind the patient. Both lobes and the isthmus of the thyroid gland should be palpated for any nodules or diffuse enlargement. Mobility of the thyroid gland with swallowing should be assessed with palpation. Nodules arising from the thyroid gland typically move with swallowing. A hard, fixed thyroid gland could indicate malignancy. If a central nodule is identified, the patient is asked to protrude the tongue. Upward movement of the central nodule on protrusion of the tongue indicates a thyroglossal cyst. Auscultation is performed at the superior poles of bilateral lobes as this is where the superior thyroid artery is most superficial and bifurcates into its terminal branches. A bilateral bruit over the superior poles suggests Graves disease. Examination of the thyroid gland is completed by palpating the regional cervical lymph nodes for any enlargement.

External jugular vein cannulation is an integral part of modern medicine and is practiced in virtually every health care setting. Venous access allows sampling of blood, as well as administration of fluids, medications, parenteral nutrition, chemotherapy, and blood products. [1] This topic describes placement of an intravenous (IV) catheter into the external jugular vein. A similar technique can be used for placement of IV catheters at different anatomic sites.
Patients are generally placed in a supine position with the head in an extended position. As noted above, Gardner-Wells tongs can be used for additional cervical traction. The hands can also be tied downward to increase the operative exposure. Once the surgical site is properly prepared with cleansing material, the appropriate surgical level is identified with intraoperative radiographs. A scalpel is used to make a linear longitudinal incision just medial to the body of the sternocleidomastoid muscle. The incision is made long enough to include at least 2 vertebral levels if a 1-level discectomy is being performed. Alternatively, transverse skin incisions over the targeted vertebral level can also be performed. The platysmal muscle is identified and incised. The platysmal incision can be extended if a multilevel decompression is the surgical aim. Extensive subplatysmal dissection is performed to reduce retraction injury.
This is a surgery showing the removal of a large exostosis. Exostoses are bony growths in the ear canal from chronic exposure to cold water/air, most commonly from surfing. This patient had growths in both ears, which were completely obstructing the ear canals. This patient had a single exostosis that was blocking this side (the right side).
Bunions can be very painful. ... Bunion removal is a surgical procedure that corrects a deformed area of the foot near the big toe. Bunion removal is sometimes called a bunionectomy, bunion surgery, or hallux valgus correction. Hallux valgus is a Latin phrase that means “foot deformity
Transvenous cardiac pacing, also called endocardial pacing, is a potentially life saving intervention used primarily to correct profound bradycardia. It can be used to treat symptomatic bradycardias that do not respond to transcutaneous pacing or to drug therapy.
In the Dialysis Unit you have an opportunity to provide Dialysis care for a variety of patients, including those with End-Stage Chronic Kidney disease and acutely ill patients requiring dialysis and plasmapheresis.
The Chronic Dialysis Nurse focuses on patients receiving Hemodialysis, Peritoneal Dialysis, or Home Hemodialysis. Our patients range in age from newborns to young adults. The Hemodialysis patient receives their dialysis treatment in the clinic 3-5 times a week. The Peritoneal Dialysis and Home Hemodialysis treatments are provided in the patient’s home once the parent/caregiver is trained to operate the machine. They are followed monthly in clinic. The patient receiving Chronic Dialysis is supported by a multidisciplinary team that consists of a physician, nurses, social worker, nutritionist, pharmacist, child-life therapist, teacher, and counselor. The group works together to meet the medical and emotional needs of the patient and caregiver. Care is specialized to meet the needs of each individual patient.
The Acute Dialysis Nurse focuses on acute dialysis related therapies such as: Continuous Renal Replacement Therapy (CRRT); therapeutic plasmapheresis; or acute peritoneal dialysis. The acute dialysis team works with the multi-disciplinary inpatient nephrology team to provide acute dialysis services to the critically ill ICU patients. The work environment is highly technical and fast-paced.
The Dialysis Unit operates on 12hr shifts 7a – 7p; 7 days a week. Night call is required and shared by the nurses. We provide a detailed orientation plan to the nurse to become proficient in providing hemodialysis, peritoneal dialysis, continuous renal replacement therapy and plasmapheresis. Previous experience in dialysis or pediatrics is not required.
