Erb's Palsy and Klumpke's palsy

-

Erb's palsy refers to a palsy involving C5-6 of the brachial plexus. It often occurs in neonates due to traction injury to the arm usually during birth. Erb's palsy affects the deltoids, the biceps and the brachialis muscles and may also affect sensation in the axillary and musculocutaneous (lateral) distribution. people with Erb's palsy have difficulty supinating the forearm, flexing the arm at the elbow and abbducting the arm, leaving the arm in a 'waiter's tip' position.

Klumpke's paralysis refers to the paralysis of the lower brachial plexus (C8-T1). It affects the intrinsic muscles of the hand, the flexors of the fingers and the wrist and the pronators of the forearm resulting in a 'clawed hand' and may also cause constriction of the pupils, ptosis, and anhydrosis (honer's syndrome).

Pleural effusion

Definition Pleural effusion is a collection of fluid in the pleural space between the visceral pleura surounding the lungs and the parietal pleural attatched to the throacic wall. Demographics Pleural effusions are relatively common, but it is a manifestation of other underlying diseases. The prevalence and incidence of pleural effusions is therefore dependent on it's cause. Pathophysiology/causes Pleural fluid is usually filtered from the parietal pleura into the pleural space, due to hydrostatic pressure from the capillaries, negative pressure in the pleural space and pleural oncotic pressure. The visceral pleura is perfused by the pulmonary system which has a lower pressure, and fluid in the pleural space is therefore drawn back in through the visceral pleura due to the higher oncotic pressure in plasma. Some of this fluid is then drained by the lymphatic system.

Fluid Management Part 1

Fluid compartments:   The body is made of about 60% water, which is divided between the intracellular and extracellular space. Fluid is distributed in these spaces by osmotic forces determined by ion distribution between the intracellular and extraceullular space. Approximately 2/3rds (40% total body weight) of the body’s fluids is distributed in the intracellular space and 1/3rd (20%)in the extracellular space.
