A web application to reduce drug calculation errors with veterinary anesthetic protocols.
Popular tools currently in use:
- blank forms where medical staff manually write in and calculate drug dosages using a calculator
- excel spreadsheets where some calculations can be automated but are prone to user error through spreadsheet interference
- Allows custom protocols for cats and dogs by entering each required drug and the required dose individually.
- Auto populates protocols for healthy cats and dogs with the click of a button.
- Calculates drug dosages for anesthesia, Fentanyl (pain) continuous rate infusion, fluid rates, and emergency drugs.
Create project directory
mkdir <projectname>
cd <projectname>
Create and activate a virtual environment
python3 -m venv ~/venvs/project_venv_name
source ~/venvs/project_name/bin/activate
Create a database
This project uses postgreSQL but any database can be used with the frontend.
psql
create database <databasename>_development;
create user <username> with password '<password>';
alter database <databasename>_development owner to <username>;

Install dependencies
- Django
- Django Rest Framework
- Django CORS Headers
- Python Dotenv
- Psycopg2pi
- DJ Database URL
- Whitenoise
pip install django djangorestframework django-cors-headers python-dotenv psycopg2 dj-database-url whitenoise
Start the django project
django-admin startproject <project_name>
Create a Django app in same directory as manage.py
python manage.py startapp <app_name>
Database setup
On same level as manage.py, creates a .env file and paste the following into it.
DATABASE_URL=‘postgres://postgres:postgres@127.0.0.1:5432/<database_name>’
In <project_name>/settings.py, update the following to use PostgresSQL
import os
import dj-database-url
from dotenv import load_dotenv
load_dotenv()
DATABASES = {
'default': dj_database_url.config(default=os.environ['DATABASE_URL'], conn_max_age=600)
}
Add CORS
-
Install library
pip install django-cors-headers -
Add in proper place in your INSTALLED_APPS in settings.py - after the rest_framework and before your application myapp
'rest_framework',
'corsheaders',
'myapp.apps.MyAppConfig',
-
Allow the origins for your api (inside settings.py)
CORS_ORIGIN_WHITELIST = ('http://localhost:3000', # for localhost (REACT Default)) -
In settings.py, update MIDDLEWARE at top of the list
'corsheaders.middleware.CorsMiddleware', -
In settings.py, confirm
CORS_ALLOWED_ORIGINS = ['http://localhost:3000',]
Veterinary Anesthesia Protocol - Frontend
- Ability by user to add standard protocols to autopopulate form.
- Ability by user to store protocols for individual patients to recall for reference or usage at a later time.
- Ability by user to add drugs to the database.
- User login and authentication to allow above actions.
- Printable document with generated protocol and monitoring grid for use by anesthetist on the medical floor.
