3.2. Heart Rate Variation
bradycardia, vomiting, nausea, hypotension
The mean heart rate (HR) variations at the onset of study T0 and T1-T2 were approximately equal in both groups; but in the intervention group, heart rate was higher than that in the control group in times of T3–T8, and this difference was statistically significant (The incidence of hypotension, bradycardia, nausea, and vomiting and the amount of prescribed ephedrine, atropine, and ondansetron in the control group were higher than in the intervention group, and the difference was statistically significant (
