About the reviewer

PrepSurgeryPrep is written and reviewed by Dr. Saurabh Shukla (MBBS, DNB Anesthesiology), a qualified anesthesiologist. Anesthesiologists are the doctors responsible for keeping patients safe before, during, and after surgery — including the fasting, medication, and risk decisions this site explains.

For readers outside India: MBBS is the primary medical degree (equivalent to an MD in the US), and DNB Anesthesiology is a postgraduate specialist qualification in anesthesiology, equivalent to completing residency training in the specialty.

How we review medical content

Every clinical page follows the same process:

1. Drafted in plain language around a specific question people actually ask before or after surgery.
2. Checked against published guidance from recognised bodies (see sources below) — and where sources differ, we take the more cautious figure.
3. Reviewed by an anesthesiologist (Dr. Shukla) for clinical accuracy and safe framing.
4. Dated and revisited — pages carry a "last reviewed" date and are updated when guidance changes.

Our tools and calculators use the same sourced rules. They give general guidance and always defer to the specific instructions of your own surgical and anesthetic team.

Our sources

Guidance on this site is based on mainstream clinical sources, including:

• American Society of Anesthesiologists (ASA) — fasting and peri-operative standards
• European Society of Anaesthesiology and Intensive Care (ESAIC)
• UK NICE and NHS patient guidance
• ACC/AHA — peri-operative cardiac and anticoagulation guidance
• ASRA — regional anesthesia and anticoagulation timing
• Surgical-society and hospital patient-information leaflets for procedure-specific recovery

Editorial independence

The site is free and carries some advertising to cover its costs. Advertisers have no say in our content — what we say about fasting, medicines, risk and recovery is decided on clinical grounds alone. We don't sell your data, and the tools run entirely in your browser: nothing you enter is stored on a server.

Update log

• June 2026 — Added the guided My Surgery Plan tool, a "what to do if you slipped up before surgery" decision aid, anesthesia-reassurance and pre-op-appointment guidance, and expanded fasting Q&A. Clinician references re-checked.
• June 2026 — Full site review and redesign; medication, fasting and recovery tools re-checked against current guidance.

Important limits

This site provides general educational information, not personal medical advice. It cannot see your full medical situation. Always follow the specific instructions of your own surgeon and anesthesiologist — if they differ from what you read here, follow them. Do not use this site for emergency situations.
