Intraoperative systemic vascular resistance is associated with postoperative nausea and vomiting after laparoscopic hysterectomy

Table 2 Predictors of postoperative nausea and vomiting

Variables	Univariate analysis	Binary logistic regression analysis
	P value	OR (95%CI)	P value
Duration of surgery (min)	0.017	1.316 (1.003-2.030)	0.012
SVR mean (dyn*s/cm5)	0.050	1.015 (1.005-1.109)	0.047
BMI (kg/m2)	0.064		0.410
SVR baseline (dyn*s/cm5)	0.029		0.189
SVR AUC (dyn*s/cm5*min)	0.015		0.969

SVR: Systemic vascular resistance; AUC: Area under curve; OR: Odds ratio; BMI: Body mass index.
