About

iTIVA Anesthesia

This medical simulation app models drug distribution and TCI pump behavior for intravenous anesthesia. It helps users understand pharmacokinetics and calculate infusion rates based on various mathematical and pharmacokinetic models. Designed for educational purposes, it allows for up to three drug simulations simultaneously.

Highlights
  • TCI pump simulation
  • Drug distribution modeling
  • Pharmacokinetic models
  • Infusion rate calculation
  • Up to 3 drugs simultaneously
  • End tidal gas calculation

TRY IT FOR FREE, 10 USES WITHOUT TIME RESTRICTIONS! iTIVA is a simulation program that provides information about distribution of drugs based on mathematical models, and it simulate the behavior of a TCI pump (up to 3 drugs at time), obtaining infusion rates to reach and maintain a stable target effect site concentration, those schemes can be implemented in volumetric infusion pumps, and be guided with pharmacokinetics models. So now pharmacokinetics can become an easy topic and understanding what is going on during a infusion of a intravenous drug, too. Pharmacokinetic models iTIVA include 11 drugs and 40 pharmacokinetic models, that are updated continuously: -Remifentanil Adults: Minto

Anesthesiologist is designed to help quickly calculate adult and pediatric anesthesia related information. Useful for anesthesiologists, CRNA, ER and critical care physicians, as well as medical students, residents, and fellows. Drug dosing and airway management information is calculated on the basis of patient weight and age. The app is a work in progress; please see "What's new" for updates about included information. Airway: Mask size Laryngoscope blade size Endotracheal tube size Laryngeal mask airway (LMA) size and ETT it will admit Drugs including IM and rapid sequence induction dosing: Succinylcholine Rocuronium Cisatracurium Vecuronium Propofol Etomidate Ketamine Thiopental Fentanyl Hydromorphone Morphine Ketorolac Acetaminophen Ondansetron Dexamethasone Metoclopramide Epinephrine Amiodarone Phenylephrine Ephedrine Midazolam Clonidine Glycopyrrolate Atropine Neostigmine Cefazolin Ceftriaxone Ampicillin Cefoxitin Clindamycin Gentamicin Vancomycin Infusions: Remifentanil Propofol Dopamine Dobutamine Epinephrine Isoproterenol Norepinephrine Milrinone Phenylephrine Vasopressin Nitroglycerin Nitroprusside Esmolol Obstetric drugs: Magnesium Oxytocin Methergine Carboprost (Hemabate) Terbutaline Copyright 2011 Vikas Shah.

Verdict

The call

The clearest difference is in-app purchases: Anesthesiologists at none against iTIVA Anesthesia's 1. Anesthesiologists also leads on rating (5.0 vs 4.6) and review sentiment (100% vs 90%). iTIVA Anesthesia's advantage is update cadence (every 3 months vs every 17 months) and ratings volume (45 vs 5). On price, ads, monetization model and device support there is nothing between them.
