However, sudden and permanent desaturation, severe hypotension, hypocarbia, and tachycardia were observed during the cyst excision.
The changes in pulse rates at various times after induction in both the groups when tested by Analysis Of Variance were found to be insignificant (P>0.05).Nothing in contravention to the findings of the other investigators could be demonstrated with regard to variations in Sp[O.sub.2] or any influence of these breathing systems on Oxygenation, Pulse rate and Mean arterial pressures, in spite of induced hypocarbia and concomitant rebreathing which was even higher with Bain breathing system.
As a result, it transfers approximately 10 times more efficiently than oxygen, sometimes necessitating the use of carbon dioxide enriched fresh gas in order to prevent hypocarbia. A comparison between pre- and postoxygenator blood samples should reveal an increase in Pa[O.sub.2] and a decrease in PaC[O.sub.2].
Ventilation strategies include high concentrations of oxygen, low tidal volumes (6 ml/kg of predicted body weight), a respiratory rate sufficient to achieve mild hypocarbia and optimum levels of positive end-expiratory pressure (5--15 cm[H.sub.2]O).
Hyperbilirubinemia, hypocarbia and periventricular leukomalacia in preterm infants.
Randomised study comparing extent of hypocarbia in preterm infants during conventional and patient triggered ventilation.
Extracranial events such as hypotension, hypocarbia, hypoxia, acidosis, anemia, hyperglycemia, and hyperthermia further contribute to secondary brain injury (Engstrom et al., 2005; Jeremitsky, Omert, Dunham, Protetch, & Rodriguez, 2003; Littlejohns & Bader, 2005; Shahlaie, Boggan, Latchaw, Ji, & Muizelaar, 2008).
