Study of correlation between maternal fatigue and uterine contraction pattern in the active phase of labour

Offering strategies to prevent tiredness and reduce the related fatigue complications.

An Integrated Review of Uterine Activity Monitoring for Evaluating Labor Dystocia

“…The sample included papers published between 2002 and 2016 that originated in 6 countries: the United States, Canada, Slovenia, Iran, South Africa, and the Netherlands. Sample sizes ranged from 28 to 36 women in 3 smaller feasibility studies, [10][11][12] 100 to 200 women in 7 observational case-control and cohort studies, [13][14][15][16][17][18][19] and 503 women in one randomized controlled trial. 20 Eight studies included only nulliparous women, [11][12][13][14][16][17][18][19] whereas 3 included women of any parity.…”

“…Findings from an earlier study by the same group indicated that contraction frequency was not significantly associated with maternal self-report of fatigue in nulliparous women in spontaneous labor with a singleton fetus in vertex position at term gestation (N = 100). 16 Contraction duration and uterine resting time are other potentially relevant temporal measures of uterine activity; however, they were not reported in any of the identified studies. Overall, findings of the included studies suggested that decreased contraction frequency may be characteristic of a labor pattern resulting in cesarean birth, but limited precision for identifying such patterns was demonstrated.…”

“…The fall-to-rise ratio is a measure of contraction shape calculated as the time in seconds from the peak of the contraction to return to baseline divided by the time from contraction onset to the contraction peak (Figure 3). 16 The fall-to-rise ratio was reported in 4 studies, [15][16][17][18] 3 of which were conducted by the same research group in Iran. [15][16][17] Increased fall-to-rise ratio, which indicates a contraction that has a prolonged fall time compared with the rise time, was hypothesized by the researchers to indicate slow recovery of the uterine muscle following contraction.…”

Comparison the Effect of Anethum graveolens and Oxytocin on Induction of Labor in Term Pregnancy: A Randomized Clinical Trial

“…Driggers et al (35) stated that F:R time was longer in dystocia group, but some studies said F:R time in dill group due to its contents such as limonene and tannin was shorter than that of the control group. This pattern of contractions leads to shorter labor (36).…”
