Summary

The purpose of this study is to investigate the effect of different crystalloid coload volumes on the 90% effective dose of prophylactic norepinephrine infusions for preventing postspinal anesthesia hypotension during cesarean section.

Conditions

  • Adverse Effect

Interventions

DRUG

Crystalloid - 0 ml/kg

No fluid coload was given. An initial infusion dose of prophylactic norepinephrine (0.025 ug/kg/min) simultaneous with spinal anesthesia. The dose administered to subsequent patients varied by increments or decrements of 0.005 ug/kg/min of prophylactic norepinephrine according to the responses of previous patients according to the up-down sequential allocation.

DRUG

Crystalloid - 5 ml/kg

5 ml/kg crystalloid coload combined with an initial infusion dose of prophylactic norepinephrine (0.025 ug/kg/min) simultaneous with spinal anesthesia. The dose administered to subsequent patients varied by increments or decrements of 0.005 ug/kg/min of prophylactic norepinephrine according to the responses of previous patients according to the up-down sequential allocation.

DRUG

Crystalloid - 10 ml/kg

10 ml/kg crystalloid coload combined with an initial infusion dose of prophylactic norepinephrine (0.025 ug/kg/min) simultaneous with spinal anesthesia. The dose administered to subsequent patients varied by increments or decrements of 0.005 ug/kg/min of prophylactic norepinephrine according to the responses of previous patients according to the up-down sequential allocation.
