Noxious stimulation such as skull pin insertion for craniotomy elicits a significant hemodynamic response. Both regional analgesic techniques (pin-site infiltration [PSI] and scalp block [SB]), systemic strategies (opioids, alpha-2 agonists, anesthetics, beta-blockers) have shown to attenuate this Analgesia Nociception Index (ANI) provides objective information about the magnitude of nociception adequacy analgesia. This study compared ANI changes in patients receiving local anesthetic SB versus PSI during application craniotomy.Sixty adult scheduled elective supratentorial tumor surgery were randomly allocated receive or after induction anesthesia. Data regarding heart rate (HR), blood pressure (BP), collected every minute 5 min beginning from baseline.A difference was observed values between (higher ANI) groups insertion, P < 0.001 = 0.003 ANIi ANIm, respectively. Similarly, seen HR BP both within two (P both). The duration change smaller group with parameters studied. A strong negative linear correlation noted parameters.The HR, BP, significantly less undergoing craniotomy.
