polycythemia IN HEIGHT AND THE BLEEDING
According Monge, 1928, chronic mountain sickness (MMC) is a disease that affects native or resident of the height. The pathophysiology is explained by the Polycythemia or excessive erythrocytosis secondary to pulmonary hypoventilation, hypoxemia. See this blog CHRONIC altitude sickness. " Fernando Acosta
diligent doctor of Cerro de Pasco in the eighties always repeated that at Cerro de Pasco at 4330 m, many locals over 40 years, with economic capacity to do so, to meet and hear frequently about the deaths of friends or relatives by a stroke called "sprawl" related to polycythemia, fleeing to lower altitudes sometimes out of fear or sometimes because they felt some discomfort secondary to hyperviscosity of polycythemia and left their villages with no penalty to keep ahead in their development.
Polycythemia with excessively high hemoglobin levels above the physiological level according to altitude, up to 29 g / dl of hemoglobin have had the opportunity to see, apart from an indication of their descent to sea level treatment final, has tried to be determined by pharmacological methods as medroxyprogesterone, the almitrine, methylxanthines, adrenergic blockers, ACE inhibitors, acetazolamide, etc.. Fabiola León Velarde nationally recognized researcher on the height of the Cayetano Heredia University in Lima led the group consensus of Xining, China in 2004 looking for a pharmacological solution polycythemia.
Sangria with isovolemic replacement the only option today
However, MMC and polycythemia overwhelmed 4-5% of the population in height between 40-60 years (see this blog HEIGHT ADJUSTMENT AND HEMOGLOBIN ) and pharmacological treatment is feasible, for the moment for such a large population living more than 3000 meters.
The other problem of infeasibility in treatment is the inability of all the affected population is transferred to sea levels.
Thus far the only treatment of polycythemia is bleeding or so-called phlebotomy in Anglo-Saxon literature.
bleeding or removal of a quantity of blood through a peripheral vein has been known since the time of the Inca Empire in our country with large populations of height. J. Sánchez Castillo revises Garcilaso de la Vega in his blog PERUVIAN HISTORY OF MEDICINE, which used this technique called Hampicamayoc bleeding or purging probablemente para resolver empíricamente síntomas relacionados a la policitemia.
Porque si se ha demostrado correlato fisiopatológico en este tratamiento, Cruz y Marticorena en el Hospital de Chulec describieron en “Phlebotomy improves Pulmonary Gas Exchange in Chronic Mountain Polycythemia, Respiration 1979: 38: 305-313”, y encontraron que la sangría mejoraba el intercambio de gases y la espirometría en los pacientes policitémicos.
Las sangrías hasta la fecha, por lo tanto, son el procedimiento de elección para el tratamiento de la policitemia sintomática y estas se siguen realizando en nuestros hospitales ubicados a gran altura. Se realizan SANGRÍAS CON REPOSICIÓN isovolemic physiological solutions.
Oscar Sedano of Huancayo, another renowned medical researcher of the height, in his "non-pharmacological reduction of excessive erythrocytosis induced by isovolemic hemodilution in the MMC" has shown that isovolemic replenishment associated with the bleeding, reduce the symptoms for more time after three indentations of up to 15 months and also measured the rate of reduction of hemoglobin for each assignment of bleeding as follows: 1st: 4.1%, 2nd: 6.2%, 3rd: 5.5%.
In conclusion so far the only viable treatment for remaining in the polycythemic height is bleeding with isovolemic replacement.
