Seattle Children'sA nerve-block reference app for pediatric anesthesia
Essential Regional turns a binder of regional anesthesia references into one iOS app: pick the procedure area on a 3D figure, choose the blocks, see the sonoanatomy, and calculate a safe dose for this patient.

Overview
Pediatric anesthesiologists performing ultrasound-guided regional nerve blocks work from reference manuals: which blocks cover a procedure area, what the target looks like on ultrasound, and the maximum safe dose for a patient's weight. Seattle Children's wanted that reference in the clinician's pocket, on the hospital's brand.
The challenge
Three things a clinician needs fast live in three different places in a paper manual, and dose math happens on a notepad. The app had to compress the binder without dumbing it down, and it had to be trusted by people who will not forgive a wrong number.
The approach
Anatomy as the navigation. Procedure-area selection on a rotatable 3D figure with dermatome overlays that show exactly what each block covers, then block selection with a deep-tissue toggle so the list matches what is on screen.
Reference where the decision is made. Each block pairs its sonoanatomy illustration with the ultrasound image and clinical pearls, drawn from the reference sources the department already trusted.
A calculator that respects the stakes. Patient weight, agent, and concentration in, maximum bolus and infusion volumes out, with the math shown so a clinician can check it.
The hospital's system. A style guide on Seattle Children's palette, Montserrat type scale, iconography, and button and input states, so the product reads as the institution's, not a vendor's.
The outcome
A working prototype and complete design package: information architecture, flows, every screen, icon set, style guide, and production assets, handed to the build team. Clinical content and usage data belong to the hospital.
