Background and Objective: The results of previous studies show the neonate position is effective in improving oxygenation . Therefore, this study aimed to compare the prone and supine positions on oxygen saturation in preterm infants who were weaned from mechanical ventilation. Materials and Methods: This clinical trial carried out on 40 preterm infants who were weaned from mechan...
Background: Acute lymphoblastic leukemia (ALL) affects both children and adults, with a peak incidence between the ages of 2 and 5 years. ALL cells sometimes penetrate the central nervous system (CNS) and patients with CNS diseases at initial presentation have been reported to experience a significantly greater risk of treatment failure compared with CNS negative patients. This study hypothesiz...
Background: Premature infants with respiratory distress syndrome (RDS) are in dire need of respiratory support with a ventilator. However, the high tidal volume of mechanical ventilation may cause lung injury, and researchers have been concerned with the use of nasal continuous positive airway pressure (NCPAP). NCPAP has concomitant side effects, such as abdominal distention, which might disrup...
OBJECTIVES: To analyze the influence of lying in prone position on a specially designed stretcher on the maternal-fetal hemodynamic parameters and comfort of pregnant women. METHODS: A randomized, controlled trial with 33 pregnant women divided into 2 groups: pregnant group sequence 1 and pregnant group sequence 2. The order of positions used in sequence 1 was Fowler's position, prone positio...
Purpose: To study the simultaneous effects of prone position and anesthesia on intraocular pressure (IOP) and the time impact on post anesthesia visual loss development in percutaneous nephrolithotomy (PCNL). Materials and Methods: Twenty patients who were candidates for PCNL were recruited in this study. Intraocular pressure was measured in five occasions: 1. Base line; 2. Ten minutes after an...
The rapid improvement in blood oxygenation has been observed in patients with acute respiratory failure placed in a prone position. The gravitational effect relieves upper airway narrowing in the prone position, resulting in an improvement in sleep quality. This study examined the effect of the prone position on autonomic nerve activity and cardiovascular function. Seven healthy adults (mean ag...
BACKGROUND Intraoperative intraocular pressure (IOP) in the prone position and IOP changes over time have not been evaluated in pediatric surgical patients. We sought to determine time-dependent changes in IOP in children undergoing surgery in prone position. METHODS Thirty patients undergoing neurosurgical procedures in prone position were included. Using a pulse-mode pneumatonometer, IOP wa...
Background : Neonatal period is one of the most important periods in human's life. Low birth weight and immaturity is often the cause of death. (weight less them 1000grm and pregnancy less than 30 weeks). One of the main cause of death in this period is respiratory distress syndrome. Objective : To determine the effect of prone and supine positioning oxygenation in preterm infants with resp...
