Description of intervention(s) / exposure
The aim of this study is to compare the concentration of fentanyl between maternal and cord blood in women administered intranasal (IN) or subcutaneous (SC) fentanyl for labour analgesia. Corresponding 3mL maternal and 1-3mL umbilical cord blood samples will be collected from women administered intrapartum fentanyl and their neonates. Duration of observation includes the time from first fentanyl dose administered in labour to 30 minutes post birth.
Intervention code [1] 301314 0
Not applicable
Comparator / control treatment
Samples will be collected at the time of birth (where possible within 30 minutes of birth) and not at a predetermined time following maternal dosing. As such, plasma concentration ratios are used as an indicator of fetal exposure to the drug relative to the mother.
Control group
Active

Statistical methods / analysis
Data will be collected and entered electronically into SPSS version 21. Nominal data will be analysed using chi-square and ordinal data using Mann-Whitney U test. Descriptive statistics will be used to report frequencies, means and standard deviations or median and interquartile range. Data comparing maternal and cord plasma concentration ratios will be compared using two-tailed paired and unpaired t-tests or Mann-Whitney U tests where appropriate. These results will be presented as mean difference and 95% confidence interval. Statistical significance will be set at p<0.05.
