Entonox (N<jats:sub>2<\/jats:sub>O<jats:sub>2<\/jats:sub>) which is an inhalational gas for relieving labor pain is commonly used intermittently; however some women are interested in continuous breathing in face mask. So we decided to compare the complications induced by two methods to find out whether it is safe to permit the mothers to use Entonox continuously or not.<jats:italic>Patients and Methods<\/jats:italic>. This randomized clinical trial was performed in Mobini Hospital, Sabzevar, Iran. 50 parturients used Entonox intermittently and 50 cases used it continuously during labor.
