Bicarbonate: (Decreased)
See ABG – may represent a metabolic acidosis (and causes) – also consider a Respiratory Alkalosis
Data Trace Editor
Bicarbonate, Sodium
* ACLS guidelines no longer include this as a part of resusitation unless there is hyperkalemia or pre-existing acidosis; * Adult: based on blood gas values or empirically: * Supplied: 50 ml vials (44 mEq/vial) (almost 1 mEq/ml) * Dose 1 mEq/kg IV (50-100 mEq or 1-2 amp), then half the initial dose q10-15min; give … Read more

Below-Elbow Amputation
– See: Upper Extremity Prosthetics: – Discussion: – below-elbow amputation is extremely functional, and successful prosthetic rehabilitation and sustained use are achieved in 70% to 80% of patients; – forearm rotation and strength are proportional to length retained; – Long Below Elbow Stumps: – in long elbow stump w/ … Read more
Below Knee Amputation
– See: – BKA Prosthesis – Amputations in the Diabetic Patient – Pediatric BKA: – Discussion: – length considerations: – ideal bone length is between 12 to 17 cm as measured from the medial joint line; – in … Read more
Benazepril / Lotensin
is long-acting, nonsulfhydryl angiotensin II converting enzyme inhibitor. Oral doses of 10 to 20 mg qd are in treating moderate hypertension; twice daily administration may be required in some patients; in congestive failure, effective doses have ranged up to 10 milligrams daily
Bending Cantilever
– See: Broken Femoral Stems:- Discussion: – bending cantilever fatigue is caused by proximal loss of stem support while distally the stem is securely fixed; – proximal cement breaks up, but distal portion of stem remains tightly fixed in place; – subsequent medial migration or deformation of proximal stem results; – radiolucent zones develop proximally, … Read more
Bennett’s Fracture Dislocation
– See: – Rolando’s fracture – Thumb Fractures/Dislocations – X-ray Studies – Discussion: – most frequent of all thumb frx; – described in 1882 by Dr. Edward Bennet; – it is a frx dislocation, intra-articular frx at base of … Read more
Bauman’s Angle for Supracondylar Fractures
– See: Radiographs for Supracondylar Frx: – Baumann’s Angle: – humeral capitellar angle: angle between long axis of humeral shaft & growth plate of lateral condyle, will reliably predict final carrying angle after reduction; – normal is about 85-89 deg, but it is best to judge … Read more
Antibiotic Bead Pouch
– Discussion: – discussion of addition of antibiotics to cement and osteomyelitis / vancomycin in ca sulfate – after fracture stabilization has been completed, osseous defects may be filled w/ antibiotic-PMMA beads; – these beads provide local depot administration of antibiotic and maintain space for subsequent bone graft; – as noted by Keating, et … Read more
