PreOp: Perioperative Medicine

Preoperative Risk & Planning

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

Prepare for surgery with a structured clinical reference at your side. PreOp brings preoperative assessment, risk calculators, perioperative medication references and handoff tools into one app for anesthesiologists, surgeons, internists, hospitalists and residents. ASSESS AND ORGANIZE Review cardiac, airway, metabolic and medication considerations in a readiness dashboard. Organize issues to discuss with your team, explore optimization pathways and review investigation suggestions with supporting rationale. Readiness flags support assessment; they are not clearance for surgery. EXPLORE CLINICAL CALCULATORS Access tools including RCRI, STOP-BANG, Caprini VTE, ARISCAT and Apfel, alongside BMI, eGFR and anion gap. Review the context and limitations of each result rather than relying on a score alone. REVIEW MEDICATIONS AND NEURAXIAL TIMING Find perioperative medication references covering anticoagulants, antiplatelets, diabetes treatments and other drug groups. Review neuraxial timing considerations with cited guidance, including ASRA 2025. Suggested intervals do not guarantee safety: confirm dose, renal function, patient factors and local protocols. PLAN POSTOPERATIVE CARE Build a structured plan covering medication restart considerations, VTE prevention, monitoring, glucose management, OSA, delirium and pain or nausea management. Review and adapt every output before clinical use. COMMUNICATE WITH YOUR TEAM Prepare I-PASS and SBAR handoff drafts, problem lists and summaries. Organize a morning board with pending actions, and work through a perioperative safety checklist. REFERENCE AND LEARN Explore source-linked clinical content and learning material. Clinical reference content is available offline, with light and dark themes for supported screens. Internet is required for purchases, restoration and access-code activation. FREE AND PREMIUM ACCESS Start with the basic assessment, learning content and free calculators including BMI, eGFR and anion gap. Premium unlocks the full set of tools. A valid Oman annual access code provides full access for its named calendar year, ending at midnight on January 1 of the following year in Oman time.
