HEMODYNAMIC FUNCTION IN COMPARISON OF TWO TYPES OF LOCAL ANESTHESIA WITH VASOCONSTRICTOR IN DAY SURGERY: RETROSPECTIVE STUDY

INTRODUCTION: Hemodynamic changes and cardiac arrhythmias are not uncommon in clinical practice, depending on including patient features, surgical treatment and drugs administered. We describe hemodynamic changes developed in young patients, soon after a local infiltration anesthesia in day surgery. METHODS: We retrospectively assessed the hemodynamic effect of 2% lidocaine with 0,0125mg/ml adrenaline (Li & AD) administered for septorhinoplasty in 44 participants and combination of 0.5% bupivacaine and 2% lidocaine with 0.0125mg/ml adrenaline (BLi & AD) for breast augmentation in 48 participants. Blood pressure and heart rate were recorded before the introduction of general anesthesia, immediately 5.10 and 20 minutes after administration of local infiltration, anesthetic (LIA) and data were analyzed. RESULTS: The mean systolic blood pressure (SBP) in all observed measurements before general anesthesia (0), immediately, 5 minutes, 10 minutes and 20 minutes after local infiltration anesthesia was higher among patients who underwent septorinoplasty (Li & AD), in relation to patients who underwent breast augmentation (BLi & AD) (p <05). The level of diastolic blood pressure (DBP) in measurement 20 minutes compared to measurement in 10 minutes was increased by 9,52 mmHg. The septorhinoplasty group showed a significant increase in heart rate measured 20 minutes after local infiltration anesthesia with adrenaline. CONCLUSIONS: Measured transitory changes in heart rate and blood pressure after local infiltration of vasoconstrictor anesthetics in healthy patients prior to septorinoplasty and breast augmentation may be induced by endogenous and / or exogenous epinephrine. Bupivacaine solution for local infiltration analgesia reduces hemodynamic disturbances and prolongs analgesic effect. We highlight the need for careful preoperative evaluation, including anxiety assessment and treatment in all patients in day surgery.
