Pericardiocentesis in patients with and without incipient cardiac tamponade due to pericardial effusion. An easy and safe bedside approach.
Fourteen patients with pericardial effusion of various origins underwent pericardiocentesis on 16 occasions. Incipient cardiac tamponade was present on 19 occasions in 12 patients. Pericardiocentesis was carried out bedside under sterile conditions by a trained cardiologist. ⋯ Fenestration of the parietal pericardium was necessary in 5 patients because of rapid regeneration of the fluid and in one patient due to pyopericardium with cardiac constriction. Pericardiocentesis is recommended in incipient cardiac tamponade. In the hands of experienced cardiologists the drainage procedure can be carried out safely without sophisticated equipment.

Variation of body weight with age, sex and height. An index for classification of obesity.
The body weight of 472 randomly selected inhabitants of a city population was studied in relation to age, sex and height. Weight tables were constructed from multiple regression equations. The reliability of the weights obtained and the concepts of average weight and obesity are discussed. ⋯ Over- and underweight can be expressed as % of expected weight (WE), i.e. (WO-WE)/WE X 100, where WO = observed weight. WE are calculated from the formulas WE = 6 + 0.78 X (height (cm) - 100) + 0.17 X age for men and WE = 7 + 0.71 X (height (cm) - 100) + 0.17 X age for women. These formulas are the basis for the weight tables and are derived from a subsample, obtained by excluding obese subjects from the total sample.
