Design outcomes

Primary

Measure	Time frame
We will compare respiratory depression in women who underwent caesarian section by spinal anesthesia with neuraxial morphine. We will compare frequency of respiratory depression events in two subgroups (Mallampati classification 1-2 or 3-4).	—

Secondary

Measure	Time frame
Association with respiratory depression of the following: Oxygen saturation, BMI, Questionnaire (STOP) to predict risk of airway obstruction (S:having snoring or not,T:tiredness,daytime somnolence,O:observating apnea, P:presence of high blood pressure), body movement. In addition, we will compare respiratory rate measured by capnometry with respiratory rate measured noninvasively by Early Sense.	—
