Upper gastrointestinal bleeding (sometimes upper GI, UGI bleed, Upper gastrointestinal hemorrhage, gastrorrhagia) refers to bleeding in the upper gastrointestinal tract, commonly defined as bleeding arising from the esophagus, stomach, or duodenum. In fact, the proportion of UGIB cases caused by peptic ulcer disease has declined, a phenomenon that is believed to be due to the use of proton pump inhibitors (PPIs) and H pylori therapy. Duodenal ulcers are more common than gastric ulcers, but the incidence of bleeding is identical for both.
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
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.
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.

If you’re considering an epidural to help manage the pain of childbirth, you’re not alone. More than 60 percent of women delivering at hospitals elect for an epidural during labor. And with good reason: An epidural is considered one of the safest methods of pain control, with just one in 3,000 pregnancies experiencing serious complications. It’s also good for you, since you’ll remain awake and alert during the birth, as well as for your baby, since the drugs will barely reach your bloodstream (so they can’t get into hers).
