Dynamic Effects of Different Anesthetic Agents on the Immune Function of Healthy Volunteers
Sponsor: Henan Provincial People's Hospital
Summary
This study recruits healthy volunteers and randomly assigns them in a 1:1:1:1 ratio to the following groups: Propofol group, Sevoflurane group, Ciprofol group, and Control group. Subjects in the different groups will undergo anesthesia with the corresponding general anesthetic drug, while subjects in the Control group will receive no anesthesia. Peripheral blood samples will be collected at specified time points: before anesthesia induction, upon emergence from anesthesia, 24 hours after anesthesia, and 48 hours after anesthesia. Single-cell multi-omics analysis will be performed on these samples using single-cell sequencing technology. The aim is to investigate the independent effects of different general anesthetic drugs on human immune function in the absence of surgical trauma, and to further explore the potential immunomodulatory effects of commonly used clinical anesthetics.

Conditions
Interventions
Propofol group
Induction with 1.5-2.5 mg/kg IV bolus until loss of consciousness (loss of eyelash reflex), maintenance with 4-12 mg/kg/h target-controlled infusion.
Sevoflurane group
Induction with 8% concentration inhaled for approximately 2 minutes, maintenance concentration 0.5-3%.
Ciprofol group
Induction with 0.4 mg/kg IV bolus over 10-30s; if anesthesia depth is insufficient, additional doses not exceeding 0.2 mg/kg may be given; maintenance with 0.4-2.4 mg/kg/h target-controlled infusion.
Control group
subjects will not receive anesthesia but will remain in a supine position on a hospital trolley for 3 hours, after which they will be sent to the Post-Anesthesia Care Unit (PACU).
