AbstractThis cross-sectional study of one thousand parturients aims to evaluate the factors, which are associated with pain perception in labour and to identify women who will benefit most from analgesia in labour. The instrument applied was a structured questionnaire incorporating the Box numerical scale (BNS) for pain assessment. Patients who delivered by elective or emergency caesarean section and women who did not give informed consent were excluded from the study. Spearman's and Pearson's correlational analyses were applied. Pain scores showed significant correlation with age (r=- 0.087, p<0.01), parity (r=- 0.226, p<0.01), gestational age at delivery (r=- 0.074, p<0.05), onset of labour (rho=0.195, p<0.01), mode of delivery (rho=0.160, p<0.01), booking status (rho=- 0.070, p<0.05) and educational status (rho=0.182, p<0.01). Certain groups of patients would benefit from obstetric analgesia. These patients include, nulliparous patients, young patients, patients who have had labour induced, those with preterm deliveries and those with an assisted vaginal delivery especially if they are well educated.
