The "10-8-6 rule" for propofol is a classic manual algorithm for Total Intravenous Anesthesia (TIVA) in adults, involving an initial bolus (often 1 mg/kg) followed by a step-down infusion: 10 mg/kg/hr for 10 mins, then 8 mg/kg/hr for the next 10 mins, then 6 mg/kg/hr, to achieve and maintain a target blood concentration. It's a simple, weight-based method to adjust infusion rates, though more advanced Target-Controlled Infusion (TCI) systems are now common for better precision, especially in pediatrics where this rule is often inadequate.
