“…23 Acker et al observed a circadian pattern of temperature at onset of labour, although at a slightly lower level, probably because they measured temperature orally. 24 In our study, admission temperature and mean temperature followed a circadian pattern. However, this pattern was not detected for temperature higher than 1SD above the mean.…”

Objective The aim of this study was to describe the variation of normal maternal temperature during labour. Design A prospective cohort study. Setting Two hospitals in Amsterdam, the Netherlands. Population All women with a live singleton pregnancy and a gestational age of 36 weeks or more admitted to the delivery ward from June 2000 to January 2002. Methods Maternal temperature was measured rectally every 2–3 hours from admission until the beginning of second stage, and 1‐hour postpartum. Normal labour (n = 843) was defined as gestational age ≥37 weeks, spontaneous onset of labour, rupture of membranes <18 hours before birth, normal progress of labour without the need for augmentation or epidural analgesia and spontaneous vaginal delivery of a healthy infant. The remaining group was classified as abnormal (n = 2209). Main outcome measures Rectal measured temperature in degrees Celsius. Results The mean temperature during labour in the complete study population increased from 37.1°C at the beginning of labour to 37.4°C after 22 hours. Temperature in the abnormal labour group was equal to the normal labour group during the first 3 hours of labour (P > 0.05) but increased thereafter. Conclusions At the beginning of labour, temperature was 37.1°C. Temperature increased slowly during labour and was 37.4°C (2SD 1.2) after 22 hours. The upper 2SD limit for normal temperature did not follow a circadian pattern and time of day is not relevant for the classification of normal versus elevated temperature.

“…After full text screening, 62 studies were deemed eligible for inclusion in our review (see Table 1 ). Of the 62 included studies, 22 (35 %) were from the United States [ 25 – 44 ] and six (10 %) were from Germany [ 12 – 14 , 45 – 48 ]. The remaining studies included four each from Italy [ 49 – 52 ] and Nigeria [ 53 – 56 ], three (5 %) each from Iran [ 57 – 59 ] and Norway [ 60 – 62 ], two each from Israel [ 63 , 64 ] and South Africa [ 65 , 66 ], and one each from Australia [ 67 ], Austria [ 68 ], Bahrain [ 69 ], Canada [ 70 ], France [ 45 ], India [ 71 ], Ireland [ 72 ], Jordan [ 73 ], Korea [ 74 ], Kuwait [ 75 ], New Zealand [ 76 ], Pakistan [ 77 ], Philippines [ 78 ], Saudi Arabia [ 79 ], South Korea [ 80 ], and Sweden [ 81 ].…”

“…Three studies only defined the latent phase of labor (5 %) [ 40 , 55 , 76 ], while 11 studies only defined onset of the first stage of labor (18 %) (see Table 1 ) [ 32 – 34 , 38 , 47 , 62 , 68 – 70 , 73 , 78 ]. Approximately one quarter of studies provided only a definition for unspecified labor ( n = 15, 24 %) [ 12 – 14 , 25 , 30 , 36 , 37 , 39 , 43 , 44 , 46 , 48 , 49 , 52 , 58 ]. With respect to studies that defined more than one ‘type’ of labor, 10 studies (16 %) provided a definition for both active and latent phase of labor [ 2 , 28 , 29 , 54 , 60 , 67 , 72 , 75 , 81 , 82 ], while one (1.6 %) defined both active labor and unspecified labor [ 80 ].…”

“…Most studies (68 %) included measures of cervical dilation in their definition with only 20 studies omitting a specific measurement of dilatation from definitions of labor in their paper [ 12 – 14 , 25 , 29 , 30 , 32 , 33 , 35 , 37 , 40 , 46 – 48 , 61 , 62 , 70 , 73 , 76 , 83 ] (Table 1 ). Regular painful contractions were also frequently referenced in definitions of onset of labor (71 %), with only 18 studies omitting mention of contractions [ 26 , 27 , 31 , 36 , 39 , 41 – 45 , 53 , 55 , 57 , 59 , 63 , 68 , 78 , 79 ].…”

BackgroundThe diagnosis of labor onset has been described as one of the most important judgments in maternity care. There is compelling evidence that the duration of both latent and active phase labor are clinically important and require consistent approaches to measurement. In order to measure the duration of labor phases systematically, we need standard definitions of their onset. We reviewed the literature to examine definitions of labor onset and the evidentiary basis provided for these definitions.MethodsFive electronic databases were searched using predefined search terms. We included English, French and German language studies published between January 1978 and March 2014 defining the onset of latent labor and/or active labor in a population of healthy women with term births. Studies focusing exclusively on induced labor were excluded.ResultsWe included 62 studies. Four ‘types’ of labor onset were defined: latent phase, active phase, first stage and unspecified. Labor onset was most commonly defined through the presence of regular painful contractions (71 % of studies) and/or some measure of cervical dilatation (68 % of studies). However, there was considerable discrepancy about what constituted onset of labor even within ‘type’ of labor onset. The majority of studies did not provide evidentiary support for their choice of definition of labor onset.ConclusionsThere is little consensus regarding definitions of labor onset in the research literature. In order to avoid misdiagnosis of the onset of labor and identify departures from normal labor trajectories, a consistent and measurable definition of labor onset for each phase and stage is essential. In choosing standard definitions, the consequences of their use on rates of maternal and fetal morbidity must also be examined.
