Comparison between Pre-Operative Psychological Stress Induced Change in Hemodynamics with Intubation Stress
Dr. Nikhil Mathew Simon | Dr. Radhesh Hegde
Abstract: Background: Pre-operative anxiety is a very typical occurrence before surgery, frequently because of the seriousness of the dangers involved and the unfamiliar setting. Increases in systemic blood pressure, heart rate, and plasma catecholamine concentrations are brought on by preoperative anxiety as well as by stimulation of proprioceptors near the base of the tongue during laryngoscopy. In our study we tried to determine if preoperative mental stress is equivalent to physical intubation stress. Objectives: To assess and quantify the severity of anxiety in pre-operative patients and its effect on hemodynamics and compare it with the intra operative change in hemodynamics during laryngoscopy when administering general anaesthesia Methodology: This study was a prospective analytical study done in Father Muller Medical College. The day before the surgery, the patients were made to fill out the Generalised Anxiety Disorder-7 (GAD-7) questionnaire themselves after which the procedure of general anaesthesia and the surgery were then explained to following which heart rate and blood pressure were monitored. On the day of the surgery, vitals were recorded every minute for the first three minutes following intubation. The average blood pressure and heart rate were recorded and then compared to the baseline blood pressure and base heart rate. Results: 42 individuals were included in our study and it was noted that preoperative and intraoperative haemodynamic values namely heart rate and blood pressure for severely anxious patients were comparable. Conclusion: There is a correlation between the psychological strain brought on by worry and expectation before surgery and the stresses put on the body during laryngoscopy. This signifies that it is important to not only attenuate the stress during Intubation but also to alleviate the mental stress prior to the surgery.
