Comparative effect of deliberate hypotensive anesthesia using nitroglycerine vs. phentolamine on event related potentials and cognitive functions in patients undergoing septoplasty: a randomized controlled trial

Table 2 Pre and post-operative psychometric tests in patients in Nitroglycerine and Phentolamine groups

Psychometric tests		Preoperative assessment [Median (IQR)]	Postoperative assessment [Median (IQR)]	P- value	P- value between groups
PALT	Nitroglycerine group	13.5 (11.5-15.88)	13 (11.25-15)	0.034*	0.342
PALT	Phentolamine group	14.5 (12.5–15.5)	13 (12.25-15)	0.018*	0.342
BVRT	Nitroglycerine group	15 (11.25-17)	13.5 (11- 16.75)	0.013*	0.662
BVRT	Phentolamine group	14 (12–17)	13 (11–16)	0.025*	0.662

Values are expressed as median (Q1-Q3)
PALT: Paired Associate Learning Test, BVRT: Benton Visual Retention Test
Wilcoxon test was used for comparison between pre and post-operative quantitative variables, Mixed ANOVA test was used for comparing pre and post-operative quantitative variables in the two groups,
*P-value ≤ 0.05 is considered significant
