Abstract: Objective: The primary goal of the present study was to demonstrate the existence of a possible circadian variation in urgent operative deliveries.<br />Methods: All urgent caesarean sections between 1 January 2014 and 1 January 2015 with known exact onset times of operation were included in this retrospective study. Cases that were previously scheduled for elective caesarean section were excluded. Information regarding age, delivery date, onset time of operation and type of anaesthesia was collected from the database. Analyses were completed using the Statistical Package for Social Sciences (SPSS Inc., Chicago, IL, USA) version 20.0 software. The statistical significance for all analyses was set at p<0.05.<br />Results: A total of 285 urgent caesarean section deliveries were included in the study. There were 126 (44.2%) deliveries during the day shift and 159 (55.8%) during the night shift. 80 patients (28.1%) received general anaesthesia and 65 (22.8%) received spinal anaesthesia in the morning shift, whereas 54 patients (18.9%) received general anaesthesia and 86 (30.2%) received spinal anaesthesia during the night shift.<br />Conclusion: The present study suggested that urgent caesarean sections revealed a circadian rhythm during the day.
