6. Dallas 2015 2015 Proposed Treatment Recommendations In babies >34 weeks gestation receiving positive pressure ventilation, absence of spontaneous breathing despite presence of heart rate or an Apgar score 1 to 3 at ≥20 minutes of age are strong predictors of mortality or significant morbidity. In settings where resources are limited we suggest that it may be reasonable to stop assisted ventilation in babies with no spontaneous breathing despite presence of heart rate or Apgar score 1-3 at ≥20 minutes (weak recommendation, very low quality of evidence).

13. Dallas 2015 Consensus on Science statements (1) Apgar score at 20 minutes For all the outcomes, we could not find studies that reported on individual Apgar scores (1, 2 or 3) beyond 10 minutes. One very low quality study (downgraded for indirectness) reported on Apgar scores at 20 minutes but included patients with Apgar score of 0 (Nelson 1981, 36). This study reported that in babies weighing >2500 grams with Apgar score of 0- 3 at 20 minutes the mortality was 59% and 57% of patients developed cerebral palsy.

14. Dallas 2015 Consensus on Science statements Apgar score at 10 minutes For the critical outcome of death we identified low quality evidence (downgraded for imprecision) from 2 randomized studies (Laptook 2009, 1619; Natarajan 2013, F473), one study (Laptook 2009, 1619) reporting mortality of 64%, 47% and 39% for Apgar score of 1, 2 and 3 respectively, with OR – 1.42 (1.19-1.69) at 18-22 months. Other study (Natarajan 2013, 473) reported outcomes at 6-7 years, babies with Apgar scores of 1, 2 and 3 had a mortality rate of 67%, 43% and 27% respectively if were managed with induced hypothermia and 63%, 57% and 62% for those not cooled.

15. Dallas 2015 Consensus on Science statements Apgar score at 10 minutes For the critical outcome of death and/or cerebral palsy (CP) we identified low quality evidence (downgraded for imprecision) from 1 randomized study (Natarajan 2013, F473) reporting at 6-7 years of life that 67%, 83% and 33% of babies with Apgar score of 1, 2 and 3 respectively had the outcome of death/ CP if managed with induced hypothermia, and 75%, 86% and 86% if not managed with hypothermia.

16. Dallas 2015 Consensus on Science statements Apgar score at 10 minutes For the critical outcome of moderate/ severe disability we identified low quality evidence (downgraded for imprecision) from 2 randomized (Laptook 2009, 1619; Natarajan 2013, F473) one (Laptook 2009, 1619) reporting the outcome in 50%, 63% and 38% for Apgar score of 1, 2 and 3 respectively, with OR – 1.30 (1.06-1.58) at 18-22 months., the other study (Natarajan 2013, 473) reporting at 6-7 years of life that 100%, 75% and 9% of babies with Apgar score of 1, 2 and 3 respectively had moderate/ severe disability if managed with induced hypothermia, and 67%, 67% and 71% if not managed with hypothermia.

17. Dallas 2015 Consensus on Science statements No spontaneous respiration For the critical outcome of death we identified very low quality evidence (downgraded for imprecision) from 2 observational studies (Scott 1976, 712; Koppe 1984, 193) that time to spontaneous respiration for more than 30 minutes was associated with 52-77% mortality For the critical outcome of cerebral palsy or abnormal neurological findings we identified very low quality evidence (downgraded for imprecision) (Steiner 1975, 696; Scott 1976, 712; Koppe 1984, 193) that time to respiration more than 30 minutes was associated with 35% of cerebral palsy and 67-100% abnormal neurological findings

18. Dallas 2015 Consensus on Science statements No spontaneous respiration For the critical outcome of death and/ or moderate to severe disability we identified very low quality evidence (downgraded for imprecision) from 2 observational studies (Ekert 1997, 613; Shah 2006, 729) that time to spontaneous respiration of 10-19 minutes and >20 minutes was associated with this outcome in 56% and 88% of patients respectively (Ekert 1997, 613) and time to spontaneous breathing at ≥30 minutes was a predictor of this outcome – OR- 2.33 (1.27-4.27).

19. Dallas 2015 2015 Proposed Treatment Recommendations In babies >34 weeks gestation receiving positive pressure ventilation, absence of spontaneous breathing despite presence of heart rate or an Apgar score 1 to 3 at ≥20 minutes of age are strong predictors of mortality or significant morbidity. In settings where resources are limited we suggest that it may be reasonable to stop assisted ventilation in babies with no spontaneous breathing despite presence of heart rate or Apgar score 1 to 3 at ≥20 minutes (weak recommendation, very low quality of evidence).
