Popis: BACKGROUND Shivering during caesarean section (CS) under spinal anaesthesia is a common phenomenon. It could not only alter patient's physiology by increasing oxygen consumption but also affect the parturient's experience of childbirth. Shivering is thought to be associated with intraoperative hypothermia, but the risk factors and exact mechanism remain unclear. METHODS We conducted a prospective, observational study to examine the potential risk factors for intraoperative shivering, including anxiety levels. Two hundred patients undergoing elective CS under spinal anaesthesia were recruited. Parturient anxiety levels were evaluated using the State-Trait Anxiety Inventory (STAI) questionnaire. Age, weight, height, BMI, anxiety level, number of previous deliveries, sensory block level, level of education, temperature difference during surgery and American Society of Anesthesiologists score were investigated as potential risk factors. Stepwise logistic regression was used to assess the predictors for shivering. RESULTS Data from 155 parturients were analysed. Shivering incidence was 21.9% (34 parturients). The statistical model predicted 8.5% of a shivering incidence variability (R-square Nagelkerke = 0.085). Out of all measured variables, only the number of previous deliveries [(W) = 4.295 Exp(B) = 0.562 P
