bradycardia, nausea, vomiting, hypotension, shivering
There is no doubt about the low risk of the spinal anesthesia method over general anesthesia [Our findings demonstrated that the mean arterial pressure (MAP) during surgery between the time of lithotomy position changed to the supine position (T3) and when the patient was placed in the prone position (T4) up until T9 time in the intervention group were significantly higher than that in the control group. However, in the whole study period, except for T0–T2, the mean arterial pressure in the intervention group was higher than that in the control group, but it was not statistically significant. Also, the mean heart rate in the intervention group was higher than that in the control group, but it was statistically significant only in times T3–T8. Kamal et al. [In our study, the incidence of hypotension, bradycardia, nausea, and vomiting, as well as the amount of prescribed ephedrine, atropine, and ondansetron in the control group, was higher than that in the intervention group. This difference was statistically significant (In our trial, seven patients in the control group and four in the intervention group had shivering. However, this difference was not statistically significant (
