1701 PROGRESSIVE ONSET OF SPONTANEOUS AND INDUCED FETAL BREATHING

Regulation of fetal breathing.

Traditionally, the idea of transient asphyxia plus some degree of cold stimulation has been used to explain the establishment of continuous breathing at birth. This idea was nurtured by observations made in the acute fetal preparation at a time when fetal breathing was considered absent. Experimental observations made in the past two decades have challenged this traditional view. First, complet...

Spontaneous Breathing Trial a Reliable Method for Weaning in Children

Introduction  Mechanical ventilation may be lifesaving intervention,It can be associated with complications,Thus,successful weaning is constitutive.One of the factors which is  important in successful weaning is  method of weaning. It is shown that  weaning is conducted successfully by using Spontaneous Breathing Trial (SBT) through T-piece and pressure support (PS) ventilation.But few studies ...

Spontaneous Resolution of a Fetal Dural Sinus Thrombosis: One Case Report and Review of the Literatures

Spontaneous compared with induced onset of sustained ventricular tachycardia.

Electrophysiological characteristics of the modes of initiation of 16 episodes of spontaneously occurring sustained ventricular tachycardia recorded in 16 patients by two-channel ambulatory electrocardiographic monitoring were compared with the characteristics of ventricular tachycardia induced by programmed electrical stimulation. Eleven episodes of spontaneous ventricular tachycardia began af...

Relation between parvovirus B19 infection and fetal mortality and spontaneous abortion

  Background: Infection with parvovirus B19 may cause fetal losses including spontaneous abortion, intrauterine fetal death and non-immune hydropsfetalis. The aim of this study is to determine the frequency of parvovirus B19 in formalin fixed placental tissues in lost fetuses using real-time PCR method.   Methods : In this cross-sectional study, 100 formalin fixed placental tissues with unknown...
