Comparison of Hemodynamic Response following Spinal Anesthesia between Controlled Hypertensive and Normotensive Patients Undergoing Surgery below the Umbilicus: An Observational Prospective Cohort Study

Table 3

Comparison of the incidence of hypotension, bradycardia, vasopressor consumption, and atropine usage in response to bradycardia between the two groups: at Black Lion Hospital from October 30, 2019, to January 30, 2020.

Parameter	CH (n = 55)	N (n = 55)	value
SBP within ≥25% drop n (%) (hypotension)	13 (23.6%)	4 (7.3%)	0.018
Bradycardia n (%)	7 (12.72%)	7 (12.72%)	>0.05 (Ns)
Atropine n (%)	7 (12.72%)	7 (12.72%)	>0.05 (Ns)

Chi-square test with considered statistically significant, Ns: nonsignificant, SBP: systolic blood pressure.
