“…The increase in sympathetic discharge and increase in catecholamines and corticosteroids can be very unpleasant for the patient [15,16]. The need for an anesthetic agent may increase as well, if it is to be used [17].…”

“…10 It has been proven a long back that anxiety is associated with a raise in both HR and cardiac output (CO). 11,12,20 Fell et al suggested that anxiety and stress-induced adrenaline release may account for the preoperative increase in HR and CO. 21 Anxiety causes increase in catecholamine levels through sympathetic surge. Catecholamines affect CO by increasing contractility and HR.…”

Background: Though anxiety is associated with increase in heart rate and cardiac output, there is conflicting reports regarding its effect on propofol induction dose. Aims and Objectives: The aim of the study was to delineate the correlation between pre-anesthetic anxiety and heart rate on propofol requirement for induction. Materials and Methods: Total 42 patients of ASA (American Society of Anesthesiologists) physical status I and II, 13 male and 29 female, aged between 18 to 50 years and scheduled for elective surgery under general anesthesia, were enrolled in this study. Trait anxiety in the waiting room and state anxiety both in the waiting room and operating room were assessed using Spielberger's revised State-Trait Anxiety Inventory (STAI) scale. After heart rate (HR) recording, anesthesia was induced with 200 ml/hr 1% propofol infusion till loss of verbal contact. Results: Pre-anesthetic trait anxiety and HR had strong positive correlation with propofol requirement (ρ>0.6, P<0.05) while state anxiety had not. But pre-anesthetic state anxiety measured just before induction is strongly associated with increase in HR (ρ>0.6, P<0.05).Conclusion: Pre-operative anxiety should be considered and the dose of propofol should be titrated for induction accordingly. Further, larger trials with more sophisticated monitoring are needed to confirm our findings.
