Origin: Dorsal venous network The 1st 2 letters of the word “biceps” that being the muscle with which the vein is in relation, will give a mnemonic aid to retain the relative position of the basilic and cephalic veins. (B.I., Basilic Internal) Basilic vein courses… Read More
Mnemonic: ABCDEFGH Anemia: Results from ALA dehydrogenase inhibition Also causes RBC membranes to be permeable to K+ and decrease Na+/K+ ATPase leading to hemolysis Basophilic stippling Burtonian lines: Gum “lead lines” develop in 2-50% Results from subepithelial deposit of lead sulfide granules on gingival margins… Read More
Origin: C(7), C8, T1 (Brachial plexus) Course: Axilla: Medial to axillary artery and lateral to axillary vein (between axillary artery and vein) Arm: Medial to brachial artery and pierces medial intermuscular septum – no branch in arm Elbow: Behind medial epicondyle Forearm: Between 2 heads… Read More
Origin C5-T1 (Brachial plexus) Course Axilla: Starts in axilla (lateral or anterior to axillary artery) Arm: Runs along with brachial artery – initially lateral to it (in arm) and later medial to it (cubital fossa) Forearm: Enters the forearm between 2 heads of pronator teres… Read More
ATLS’ 80/70/60 rule On the basis of location of pulse palpable, minimum systolic blood pressure can be predicted as follows: Radial/Dorsalis pedis/Popliteal pulse: >80 mmHg Femoral pulse: >70 mmHg Carotid pulse: >60 mmHg Overestimation of SBP by this rule Pulse characteristics are an unreliable sign… Read More
