Abstract: The aim of this study was to describe the characteristics and outcomes of remote-dwelling pregnant people with threatened labour referred for aeromedical retrieval to a regional birthing centre, as well as factors associated with birth within 48 hours. This was a retrospective observational study of all pregnant people in the remote Central Australian region referred to the Medical Retrieval Consultation and Coordination Centre for labour weeks gestation, between 12 February 2018 – 12 February 2020. Data was extracted manually from written medical records on maternal, neonatal and retrieval mission characteristics. Univariate and multivariate statistical analysis was performed. There were 116 people referred for retrieval for labour. There were no births during transport and less than half of the cases in this cohort resulted in birth within 48 hours of retrieval. Tocolysis was frequently used. Predictors of birth with 48 hours were cervical dilatation 5cm or more, preterm gestational age and ruptured membranes in the univariate analysis. Nearly one-third of this cohort required intervention or had complications during birth. Birth during transport for threatened labour did not occur in this cohort, and more than half of retrievals did not result in birth within 48 hours, however the high risk of birth complications may offset any benefit of avoiding aeromedical transport from remote regions. Retrieval clinicians should have a lower threshold for urgent transfer in cases of ruptured membranes, cervical dilatation of 5cm or more, or gestational age is less than 37 weeks.

Abstract: Women with threatened preterm labor in remote Australia often require tocolysis in the prevention of in-flight birth during air medical retrieval. However, debate exists over the tocolytic choice. A retrospective analysis was undertaken on data containing women who required air medical retrieval for threatened preterm labor within Western Australia between the years 2013 and 2018. A total number of 236 air medical retrievals were deemed suitable for inclusion 141 received nifedipine, and 95 women received salbutamol + nifedipine. Tocolytic efficaciousness was reported in 151 cases, proportionally more (P < .05) from the women who received salbutamol + nifedipine (n = 68, 71.6%) compared with the women who received nifedipine only (n = 83, 58.9%). Those receiving salbutamol + nifedipine were more likely to suffer maternal tachycardia (n = 87 [91.6%] vs. n = 62 [44.0%]), fetal tachycardia (n = 26 [27.4%] vs. n = 13 [9.2%]), nausea (n = 17 [17.9] vs. n = 5 [3.55%]), and vomiting (n = 12 [12.6%] vs. n = 2 [1.4%]). Three women who received salbutamol + nifedipine had serious side effects including echocardiographic changes, chest pain, and metabolic and lactic acidosis. Salbutamol + nifedipine tocolysis was proven to be more effective than nifedipine only. Although salbutamol + nifedipine had increased temporary side effects, most were nonsevere and managed in-flight.
