These are normal pathological and physiological processes during spinal anaesthesia. Two drugs, norepinephrine and phenylephrine, have peripheral vasoconstrictive effects. It is unclear the effects of norepinephrine and phenylephrine on shivering and hypothermia in patients undergoing caesarean section under spinal anaesthesia.
UNASSIGNED: 240 eligible parturients will be recruited for this randomised, double-blind, controlled trial and randomly assigned to either the norepinephrine or phenylephrine groups. The primary outcome will be the incidence of shivering while secondary outcomes will include the severity of shivering, rectal temperature, incidence of hypothermia and umbilical artery blood pH value.
BACKGROUND: The Institutional Ethics Committee of The Second People's Hospital of Hefei approved the trial protocol (ID: 2023-093). The results will be published in a compliant journal. The original data will be released in December 2029 on the ResMan original data-sharing platform of the China Clinical Trial Registry (http://www.medresman.org.cn).
