Pneumothorax Easy explanation
Pneumothorax Easy explanation samer kareem 1,841 Views • 2 years ago

A pneumothorax occurs when some of the tiny air sacs (alveoli) in a baby's lung become overinflated and burst. This causes air to leak into the space between the lung and chest wall (pleural space). The most common cause of pneumothorax is respiratory distress syndrome. This is a condition that occurs in babies who are born too early (premature). The baby's lungs lack the slippery substance (surfactant) that helps them stay open. Therefore, the tiny air sacs are not able to expand as easily. If the baby is put on a breathing machine (mechanical ventilator), there is extra pressure on the baby's lungs, which can sometimes burst the air sacs.

Closed Reduction of a Distal Radius Fracture
Closed Reduction of a Distal Radius Fracture samer kareem 18,569 Views • 2 years ago

Closed Reduction of Distal Radius Fractures - Discussion: (distal radius fracture menu) - closed reduction & immobilization in plaster cast remains accepted method of treatment for majority of stable distal radius frx; - unstable fractures will often lose reduction in the cast and will slip back to the pre-reduction position; - patients should be examined for carpal tunnel symptoms before and after reduction; - carpal tunnel symptoms that do not resolve following reduction will require carpal tunnel release; - cautions: - The efficacy of closed reduction in displaced distal radius fractures. - Technique: - anesthesia: (see: anesthesia menu) - hematoma block w/ lidocaine; - w/ hematoma block surgeon should look for "flash back" of blood from hematoma, prior to injection; - references: - Regional anesthesia preferable for Colles' fracture. Controlled comparison with local anesthesia. - Neurological complications of dynamic reduction of Colles' fractures without anesthesia compared with traditional manipulation after local infiltration anesthesia. - methods of reduction: - Jones method: involves increasing deformity, applying traction, and immobilizing hand & wrist in reduced position; - placing hand & wrist in too much flexion (Cotton-Loder position) leads to median nerve compression & stiff fingers; - Bohler advocated longitudinal traction followed by extension and realignment; - consider hyper-extending the distal fragment, and then translating it distally (while in extended position) until it can be "hooked over" proximal fragment; - subsequently, the distal fragment can be flexed (or hinged) over the proximal shaft fragment; - closed reduction of distal radius fractures is facilitated by having an assistant provide counter traction (above the elbow) while the surgeon controls the distal fragment w/ both hands (both thumbs over the dorsal surface of the distal fragment); - flouroscopy: - it allows a quick, gentle, and complete reduction; - prepare are by prewrapping the arm w/ sheet cotton and have the plaster or fibroglass ready; - if flouroscopy is not available, then do not pre-wrap the extremity w/ cotton; - it will be necessary to palpate the landmarks (outer shaped of radius, radial styloid, and Lister's tubercle, in order to judge success of reduction; - casting: - generally, the surgeon will use a pre-measured double sugar sugar tong splint, which is 6-8 layers in thickness; - more than 8 layers of plaster can cause full thickness burns: - reference: Setting temperatures of synthetic casts. - position of immobilization - follow up: - radiographs: - repeat radiographs are required weekly for 2-3 weeks to ensure that there is maintenance of the reduction; - a fracture reduction that slips should be considered to be unstable and probably require fixation with (pins, or ex fix ect.) - there is some evidence that remanipulation following fracture displacement in cast is not effective for these fractures; - ultimately, whether or not a patient is satisfied with the results of non operative treatment depends heavily on th

Pruritis is itchy skin that makes you want to scratch. It can be caused by many things. Normally, itchy skin isn't serious, but it can make you uncomfortable.

A step wise approach to the pathogenesis, types, disease entities and diagnosis of vasculitis. This discussion also includes the management options of vasculitis and their adverse drug reactions. In essence, vasculitis is a clfinicopathologic process characterised by inflammation and damage of blood vessels. This may be mainly due to three pathological processes which include immune complex deposition, anti-neutrophillic antibody formation and pathological T lymphocyte response and granuloma formation. The disease entities include Wegner's granulomatosis, Churg Strauss and many others. These present with palpable purpura, unexplained renal dysfunction etc which can be diagnosed based on biopsy and angiogram.

Management of Shoulder Dystocia
Management of Shoulder Dystocia Scott 44,766 Views • 2 years ago

Shoulder dystocia is a specific case of obstructed labour whereby after the delivery of the head, the anterior shoulder of the infant cannot pass below, or requires significant manipulation to pass below, the pubic symphysis. It is diagnosed when the shoulders fail to deliver shortly after the fetal head. Shoulder dystocia is an obstetric emergency, and fetal demise can occur if the infant is not delivered, due to compression of the umbilical cord within the birth canal. It occurs in approximately 0.3-1% of vaginal births. Contemporary management of shoulder dystocia requires a calm operator and a well-thought-out plan of action. It is imperative that if not already present, help is summoned immediately after shoulder dystocia is recognized. This help may include additional nursing staff, an anesthesiologist, a pediatrician or neonatologist and an additional obstetrician or midwife. Future coordination may demonstrate that rapid response teams are best suited to attend to this emergency.
