Resuscitation of preterm newborns with low concentration oxygen versus high concentration oxygen

Resuscitation of preterm neonates with limited versus high oxygen strategy.

OBJECTIVE To determine whether a limited oxygen strategy (LOX) versus a high oxygen strategy (HOX) during delivery room resuscitation decreases oxidative stress in preterm neonates. METHODS A randomized trial of neonates of 24 to 34 weeks' gestational age (GA) who received resuscitation was performed. LOX neonates received room air as the initial resuscitation gas, and fraction of inspired ox...

Does high oxygen concentration reduce postoperative infection?

1050 April 2014 We read not only with interest but also with some surprise the review on high intraoperative oxygen concentration by Hovaguimian et al.1 that appeared recently in AnestHesiology. The authors selected 9 to 11 of 21 studies and by a meta-analysis they concluded that “intraoperative high inspired oxygen fraction decreases the risk of surgical-site infection in surgical patients rec...

Lower versus Higher Oxygen Concentration for Delivery Room Stabilisation of Preterm Neonates: Systematic Review

BACKGROUND Emerging evidence suggests that initiating delivery room respiratory support or resuscitation for term infants using lower rather than higher concentrations of oxygen reduces mortality and the risk of serious morbidity. Uncertainty exists with regard to applicability of this strategy for preterm infants who have different underlying reasons for respiratory distress and risks for harm...

High resolution imaging of intracellular oxygen concentration by phosphorescence lifetime

Optical methods using phosphorescence quenching by oxygen are suitable for sequential monitoring and non-invasive measurements for oxygen concentration (OC) imaging within cells. Phosphorescence intensity measurement is widely used with phosphorescent dyes. These dyes are ubiquitously but heterogeneously distributed inside the whole cell. The distribution of phosphorescent dye is a major disadv...
