  Maintenance moderate dose: 25 to mcg IV/IM. Total high dose: 20 to 50 mcg/kg (prolonged surgeries). Maintenance high dose: 25 mcg to half of the initial dose. Adjunct to Regional Anesthesia: 50 to mcg IM or slow IV over 3 to 5 minutes as required. Postoperative: 50 to mcg IM. May repeat dose in 1 to 2 hours as needed. Antibiotic Dosing for Children: Expert Recommendations For Children Ages 2 months to 12 years Dosing Recommendations at a Glance Amikacin 15 mg/kg/day IV given once daily Cloxacillin, Flucloxacillin mg/kg/day IV divided in 2 or 4 doses Amoxicillin mg/kg/day PO divided in 2 or 3 doses Doxycycline 5 mg/kg/day given once daily or in 2 doses. This calculation is straightforward when the rate you want (30mg/hour) and the amount of the drug in the bag (mg) are both in the same units (mg). However, if the infusion required that micrograms were to be infused each hour instead, this would first need to be converted into mg before the infusion rate was calculated, that is,   -Induction: 1 to mg/kg IV; alternatively, 1 to 2 mg/kg IV at a rate of mg/kg/min; (2 mg/kg dose provides 5 to 10 minutes of surgical anesthesia within 30 seconds)-Maintenance: The maintenance dose should be adjusted according to the patient's anesthetic needs and whether an additional anesthetic is employed.

  Less than 6 months (not mechanically ventilated): Initial dose: to mg/kg IV or to mg/kg orally every 4 to 6 hours as needed to manage pain 6 months or older; weight less than 45 kg: mg/kg IV or mg/kg orally every 4 to 6 hours as needed to manage pain. This is a general formula to administer medications in a weight-based infusion rate. It is a useful tool to determine the rate of pump medication infusion to achieve therapeutic dosing. IV Drip Rate (mL/hour) = (60min/hr * (Desired Dose in mcg/kg/min) * (Weight in kg)* (Bag Volume in mL) / ( mcg. In healthy adult individuals, the maximum allowable volume of intravenous iodine contrast is: ≤mL (with concentration mg I/mL). In patients with renal insufficiency in particular, the volume of the contrast should be as low as reasonable. However, it should not exceed x weight [kg] / creatinine [µmol/L] mL resp.

Example calculations of dose based on BSA • A useful equation for the calculation of dose based on BSA is: • Patient’s dose = Patient’s BSA (m2) x Drug dose (mg) m2 • If the adult dose of a drug is mg, calculate the approximate dose for a child with a BSA of m2, using (a) the equation and (b) Table 2.

The drug label on the medicine indicates that the medicine is supplied in 60 mg per tablet. We will use the dosage formula to calculate the correct amount of medication for one dose.

(D) 30 mg x (Q) 1 tablet = mg. Therefore, one dose will be one half (1/2) tablet (H) 60 mg.Amount of fluid (ml) / Infusion time (hours) Working out IV drip rates (gravity method): Helps you calculate the rate in whole drops per minute when administering IV bags of fluid.

The prescription states only the type and volume of fluid; you have to work out in which administration set to administer the fluid.9 Basic Intravenous Calculations OBJECTIVES • Interpret basic intravenous (IV) solution orders for peripheral infusion.

• Identify contents of commonly ordered IV fluids. • Identify average flow rates for adults who are NPO and the general rationale for variations.
