The Total Intra Venous Anesthesia Effect Versus Volatile Anesthesia, on Stress and Pain Levels, in Patients Undergoing Breast Reconstruction in Ambulatory Surgery Center Total Intra Venous Anesthesia Protocol and Stress Response.

Abstract

Aim: To compare pain and stress response through cortisol and DHEA levels, implementing. Total intra venous anesthesia (TIVA) versus general anesthesia with volatile anesthetics (VOL).

Design: This is a prospective randomized correlation study with consecutive measurements.

Methods: In an ambulatory surgical center from October of 2019 to August of 2020, patients who underwent breast reconstruction with autologous fat grafting were randomized into 2 groups. Patients in the TIVA group (n = 23) received intravenous anesthesia and those in the VOL group (n = 23) received volatile anesthesia (desflurane). Demographic, anthropometric and clinical data were recorded. Arterial systolic (SP) and diastolic (DP) blood pressure, heart rate and oxygen saturation were recorded. Pain and stress levels were evaluated through salivary cortisol and DHEA levels at 4 different time points: T0) 1 hour before induction, T1) during the induction, T2) during anesthesia maintenance, and T3) in recovery phase. Statistical analysis was performed with SPSS 25.0 at significant level α = .05.

Findings: There were no statistically significant differences between the 2 groups regarding demographic features. Interestingly that there was a statistically significant difference in the vital sign monitoring where patients in the TIVA group reported with higher levels of SP(T2) and DP (T2), whilst DHEA (T1) levels was correlated positively with patient's age and cortisol (T1) levels and negatively with DP (T3).

Conclusions: This study supports the use of TIVA as a safe and effective option for anesthesia in patients undergoing breast reconstruction with autologous fat grafting.
