Create a clean, well-formatted exam-reference PDF titled "MD Anaesthesia Finals 2026 — Recent Guidelines & Updates" that presents the following as organized flowing paragraphs (no subheadings, just clear paragraph breaks between topics), using bold only for guideline names/years for quick scanning: the DAS 2025 guidelines for unanticipated difficult tracheal intubation (replacing DAS 2015, with first-line videolaryngoscopy, earlier neuromuscular blockade, revised ABCD rescue algorithm, standardised vertical-incision eFONA, mandatory pre-induction airway assessment, and the ongoing BJA correspondence debating VL as "mandatory," eFONA landmarks, and human factors) alongside the ASA 2022 difficult airway guideline; the 2025 AHA Guidelines for CPR and ECC (replacing 2020, with ≥200J first-shock cardioversion for AF/flutter, revised TOR criteria stratified by provider level, ETCO2 not used in isolation to terminate resuscitation, head-up CPR discouraged, and new emphasis on closed-loop communication and systems-of-care handoffs) along with the NAP7 peri-operative cardiac arrest audit series (incidence ~1 in 3076 anaesthetics, obstetric arrest data with haemorrhage as leading cause, frailty/older-patient findings); the Surviving Sepsis Campaign 2026 guidelines (replacing 2021, 129 statements with 46 new, more definitive recommendations, structured post-discharge follow-up) and the German S3 Sepsis 2025 update; the ASA 2023 modular fasting update (carbohydrate clear liquids, chewing gum, pediatric 1hr vs 2hr clear liquid duration) plus ASA guidance on GLP-1 agonists and perioperative fasting, alongside the ESC 2022 perioperative cardiac risk guideline (broadened preoperative TTE criteria) and 2024 ESC/2023 ESH hypertension updates (lower SBP targets, new "elevated BP" category, renal denervation for resistant hypertension); the ASRA LAST checklist (2020, still current) and the 2023 AAGBI LAST update (cardiopulmonary bypass option, propofol/thiopental caution), plus 2025 literature on emerging lidocaine-associated LAST; the EMHG 2025 malignant hyperthermia investigation guidelines (new MHG genotype classification, updated IVCT/genetic testing pathways) and the EMHG 2024 MH crisis management update, alongside the JSA 2025 MH guideline and the 2021 EMHG perioperative consensus for MH-susceptible patients; and any current obstetric anaesthesia guidance from OAA/AAGBI on massive obstetric haemorrhage and patient blood management relevant to peripartum care. Keep the tone concise and factual, suitable for final revision, and leave generous margins for handwritten annotations. AND ANY OTHER RELEVANT GUIDELIENS
