Prepare for anesthesia cases with GlottaVue: care planning, offline references and practical tools in one app. CARE PLAN BUILDER Organize patient history, preoperative assessment, anesthetic technique, airway, medications, intraoperative fluids and postoperative care. Review a chronological draft, save it locally, and export to PDF or Word. Optional AI synthesis refines entered non-identifying details into a cohesive plan; internet access and consent are required. Only successful generations count toward the monthly allowance. PRE-SET DOSE REFERENCE Choose age and a pre-set weight to view bundled, precomputed dose tables. The main dosing flow reads these tables without performing dose calculations. A compact rolling selector offers whole-kilogram choices above 40 kg. Other named calculators and care-plan tools perform calculations from their stated inputs. VENTILATOR TOOL Enter adult height and sex for the predicted-body-weight equation to see PBW-based tidal-volume references. Browse condition-specific starting settings, targets and clinical notes with clear swipeable tabs. Pediatric and neonatal guidance remains separate from the adult PBW calculation. OFFLINE LIBRARY Browse procedures, medication and disease references, laboratory interpretation, specialty guides, regional anesthesia illustrations and crisis checklists. Follow inline links to related bundled references. YOUR WORKSPACE Arrange favorites in a readable grid, long-press categories to add favorites, save non-identifying cases, and track training experiences with CSV and Excel export. Guided case entry walks through participation, time and experience categories. Save & next similar case carries common setup into a separate entry while clearing patient categories and times. Review each case before it contributes to progress. GLOTTAVUE ASSISTANT Explore clinical questions, medications and case-planning discussions. Continue with follow-up questions, inspect available sources or choose Deep Dive. The assistant attempts source lookup; references may be unavailable and AI output may be incomplete or incorrect. A new welcome tour introduces these features to both new and returning users. Designed for anesthesia professionals and trainees. References and generated drafts support professional review and do not replace clinical judgment, local protocols or independent verification. Do not enter patient identifiers. Online AI features and optional Apple sign-in sync have separate data-sharing disclosures. Current features are free; AI usage limits apply.

Master Anesthesia's advantage is ratings volume (2K vs 3) and chart position (#148 vs unranked). On price, rating, update cadence and ads there is nothing between them.
