Continuous positive airway pressure (CPAP) has been used successfully to promote extubation in the premature infant population. The two methods of CPAP to be examined are currently used by many institutions, yet no study has compared these methods to determine which is better in the population of newborns < 1500 grams (birth weight) at supporting extubation. This randomised controlled study will examine two types of CPAP: the Infant Flow System and the Bubble CPAP. This randomised controlled, single site, clinical study is to determine whether the Bubble CPAP or the Infant Flow System (IFS) CPAP is more effective at supporting the extubation in infants of birth weights < 1500 grams. Seventy-six infants will be randomised, immediately prior to extubation, to IFS or Bubble CPAP of 5 cmH2O. The primary outcome is successful extubation, defined as not reaching failure criteria for the 7 days post-extubation. Failure criteria are defined as pH < 7.25 and PCO2 > 65 mmHg or a sustained increase in FiO2 of 0.15.
Background: Continuous Positive Airway Pressure (CPAP) has been used successfully to promote extubation in the premature infant population (Davis & Henderson-Smart, 2002). The two methods of CPAP to be examined are used by many institutions, yet no study has compared these methods to determine which is better in the population of newborns < 1500 grams (birth weight) at supporting extubation. This study may have cost savings implications. If bubble CPAP is shown to be as effective in this application neonatal intensive care units (NICUs) will have a more affordable option of providing effective CPAP.
Methods: This randomised controlled, single site, clinical study is to determine if Bubble CPAP or Infant Flow System (IFS) CPAP is more effective at supporting extubation in infants of birth weights < 1500 grams. Seventy-six infants will be randomised immediately prior to extubation to IFS or Bubble CPAP of 5 cmH2O. The primary outcome is successful extubation, defined as not reaching failure criteria for the 7 days post-extubation. Failure criteria are defined as pH < 7.25 and PCO2 > 65 mmHg or a sustained increase in FiO2 of 0.15.
Participants: Parents/guardians of eligible infants will be approached and given information regarding the study, and any questions answered. They will then be allowed to consider study participation in private. The recruiter will return at an agreed time and informed consent will be obtained from those agreeing to participate. Parents will be approached in accordance with the guidelines of the NICU @ SWCHSC. Infants are eligible if birth weight < 1500 grams, are to be extubated to CPAP and have no known airway anomalies, or suspected genetic anomalies.
Analysis: Multiple ANOVA analysis will be used for continuous variables, chi-square for categorical variables, including primary outcome.
Conclusion: The results of this study will determine which method of CPAP is the best method of supporting extubation in the < 1500 g infant.

Advances in newborn intensive care have lead to dramatic improvements in survival for the most premature infants—often weighing 1 pound at birth. Unfortunately, cerebral palsy, mental re...

Bubble continuous positive airway pressure (bCPAP) generates a variable pressure due to bubble size and frequency, and these pressure oscillations may contribute to lung recruitment and gas exchange. ...
Onset of OBSTETRIC LABOR before term (TERM BIRTH) but usually after the FETUS has become viable. In humans, it occurs sometime during the 29th through 38th week of PREGNANCY. TOCOLYSIS inhibits premature labor and can prevent the BIRTH of premature infants (INFANT, PREMATURE).
An infant having a birth weight of 2500 gm. (5.5 lb.) or less but INFANT, VERY LOW BIRTH WEIGHT is available for infants having a birth weight of 1500 grams (3.3 lb.) or less.
An infant whose weight at birth is less than 1000 grams (2.2 lbs), regardless of gestational age.
An infant whose weight at birth is less than 1500 grams (3.3 lbs), regardless of gestational age.
A human infant born before 37 weeks of GESTATION.
Pediatrics is the general medicine of childhood. Because of the developmental processes (psychological and physical) of childhood, the involvement of parents, and the social management of conditions at home and at school, pediatrics is a specialty. With ...
