A clear, practical overview of how to interpret D-dimer results in perioperative care. Explains the basic meaning of D-dimer, its cutoffs, age adjustment, and unit differences, and why postoperative day 3 (POD3) trends matter more than single values. Also outlines the modern 3-step diagnostic pathway — clinical probability → D-dimer → ultrasound — and how probability-adjusted cutoffs (1000 / 500 ng/mL) safely reduce unnecessary scans. Perfect for junior doctors, nurses, and perioperative team training or anesthesiology board preparation.

A clear, evidence-based guide to preventing central line–associated bloodstream infections (CLABSI/CRBSI). From definitions and global infection rates to risk factors, prevention bundles, ultrasound safety, and special considerations such as disinfecting caps and antimicrobial locks — all explained in a practical, perioperative context.

Volatile anesthetics such as sevoflurane and desflurane provide immobility but almost no analgesia. This article explains the true meaning of MAC—why “no movement” doesn’t necessarily mean “no pain”—and how balanced anesthesia combines analgesia, hypnosis, and immobility.

Perioperative smoking cessation reduces postoperative complications and should ideally begin ≥4 weeks before surgery. This article reviews the three main pharmacotherapies used around surgery — nicotine replacement therapy (NRT), varenicline, and bupropion — with a focus on perioperative choice, timing, and safety. We summarize evidence (including perioperative RCTs and patient-level meta-analyses), practical decision flows for short vs. longer waiting times, and exam-focused commentary for perioperative management team and anesthesiology board exams.
