Description: The purpose of this research was to investigate the cumulative impact of the number of different invasive interventions commonly employed to provide comfort, timeliness, and safety during intrapartum. The universe sampled was low risk women anticipating an uncomplicated labor. Four null hypotheses and one research question were proposed. (1) The number of different invasive intrapartum interventions (NODI) and neonates' Apgar scores are not correlated. (2) NODI and neonates' Hobel morbidity scores are not correlated. (3) NODI and fetal stress reactivity are not correlated. (4) NODI for parturients with vaginal births and parturients with cesarean births does not differ. (5) Is there a relationship between NODI and physiological distress experienced by parturients during hospitalization for childbirth?.

A random sample from the 1993 census at MacDonald Hospital for Women, University Hospitals, Cleveland, Ohio included 122 vaginal and 8 cesarean births. With SPSS-WIN, parametric statistics were used to analyze the data. All null hypotheses were rejected. For the research question, NODI was significantly associated with physiological distress (p $<$.001).

Demographic and control variables significantly associated with NODI were ethnicity (p = 0.05), parity (p $<$.001), employment (p $<$.01), hospital length of labor (p $<$.001), epidural (p $<$.001), and care provider (p $<$.01). These demographic and control variables were tested as confounders for the outcome variables. For lower Apgar scores and increased fetal stress reactivity, a greater NODI was the single significant predictor. Longer hospital length of labor (HLOL) and a greater NODI remained associated significantly with higher Hobel morbidity scores and increased physiological distress of parturients.

For cesarean birth, four univariate statistics representing NODI (p = $<$.01), parity (p = 0.04), HLOL (p $<$.001), and epidural (p = 0.02) were significant. Only HLOL remained predictive of cesarean birth after discriminant analysis. This analysis was compromised by the small cesarean birth sample (n = 8).

Conclusions were that a greater NODI was associated with lower Apgar scores, greater neonatal morbidity, increased fetal stress, and increased physiological distress for parturients. NODI has potential as an important new measure for perinatal outcome research. Refinement and further research with this variable is recommended.
