Pacientes con síndrome de distress respiratorio agudo del adulto: efectos del óxido nítrico inhalado sobre intercambio gaseoso y la hemodinamia / Patients with acute adult respiratory distress syndrome: effects of inhalated nitric oxide on gas exchange and hemodynamics

RESUMO

Adult respiratory distress syndrome is highly prevalent in intensive care units and has a high mortality. Lately, nitric oxide has been used as adjuvant therapy. To study the effects of nitric oxide inhalation in patients with adult respiratory distress syndrome, 12 patients were subjected to nitric oxide inhalation at a concentration of 10 parts per million, during 30 minutes. At the end of the nitric oxide inhalation period, there was an improvement of PaO2/FIOa ratio from 89ñ32 to 111ñ43 mm Hg and 16 percent reduction of lung shunting (Qs/Qt). Nitric oxide inhalation at a concentration of 10 parts per million improved arterial oxygenation and reduced pulmonary shunting in patients with adult respiratory distress syndrome
