Premature Birth: what the trials found

Vaginal Progesterone is established as an intervention for the management of premature birth, with reported outcomes showing 29 cases of preterm birth <37 weeks and 9 cases of preterm birth <34 weeks in one cohort 1. Additionally, 17-Hydroxyprogesterone Capronate was evaluated for mean trough levels across multiple gestational windows (20-22, 27-29, and 34-36 weeks) 3.

Other established interventions include the use of Surfactant 4 and palivizumab 5. Additionally, a 13-valent pneumococcal conjugate vaccine was shown to result in high rates of infants achieving serotype-specific Pneumococcal IgG antibody levels (ranging from 72.73% to 98.97%) one month after the infant series 2.

Recent results — preliminary, needs further review

  • An additional 2 weeks of CPAP was associated with significant improvements in alveolar volume (p<0.05) and lung diffusion (p<0.02) 9.

For the clinician treating this condition

  • Vaginal Progesterone is an established intervention for managing the risks associated with preterm birth 1.
  • Surfactant and palivizumab are established interventions in the context of premature birth management [4, 5].
  • Extended CPAP duration (2 weeks) has been shown to improve lung diffusion and alveolar volume 9.
