Risk Management and Prevention

Pre-op Pitstop - Spotting Trouble Early

• Goal: Identify risks, optimize, plan safe anesthesia.
• History (AMPLE): Allergies, Medications, Past Med Hx, Last Meal, Events. 📌
• Airway Assessment: Crucial for intubation plan.
  • Mallampati Score (I-IV)
  • Thyromental Distance (TMD): >6.5 cm
  • Inter-Incisor Gap (IIG): >3 cm
  • Neck Movement, Dental status.
• ASA Physical Status: (I-VI) Predicts perioperative risk.
• Investigations: Targeted (Hx, exam based); e.g., Hb, ECG.
• Optimization: Optimize co-morbidities (DM, HTN, Asthma).
• Informed Consent: Mandatory.

  ⭐ ASA physical status is a robust independent predictor of perioperative morbidity and mortality.

In-Op Shield Wall - Guarding Mid-Surgery

• Vigilance & Monitoring:
  • ASA Standard Monitors: ECG, NIBP, SpO2, EtCO2, Temperature.
  • Advanced (as indicated): IBP, CVP, TEE, Neuromonitoring.
• Equipment & Drugs:
  • Anesthesia machine check (e.g., AMBU bag ready).
  • Meticulous drug labeling: right drug, dose, route. 📌 "Syringe Swaps Sink Ships".
• Patient Safety:
  • Secure airway; aspiration precautions.
  • Careful positioning: prevent nerve/pressure injuries.
• Crisis Management:
  • Protocols for Malignant Hyperthermia (MH), anaphylaxis, Local Anesthetic Systemic Toxicity (LAST).
  • WHO Surgical Safety Checklist adherence.

⭐ Capnography (EtCO2) is crucial for confirming tracheal intubation & early detection of cardiorespiratory events.

Crisis Control Crew - Tackling Anesthetic Storms

Rapid, coordinated response to life-threatening events. Focus: early recognition, teamwork, clear communication, protocol adherence.

• Core Actions:
  • Recognize crisis early (e.g., desaturation, hemodynamic instability).
  • Call for help immediately (senior cover, extra hands).
  • Allocate roles: Leader, Airway, Drugs, Scribe.
  • Administer 100% Oxygen.
  • Utilize cognitive aids: Emergency manuals, checklists (e.g., MH, anaphylaxis).
• Team Dynamics:
  • Employ closed-loop communication.
  • Regular simulation training enhances team performance.
• Post-Event: Conduct thorough debriefing for system improvement.

⭐ For Malignant Hyperthermia (MH), the initial IV dose of Dantrolene is 2.5 mg/kg. Early administration is critical.

Recovery & Records - Post-Op Safety Net

• PACU (Post-Anesthesia Care Unit):
  • Intensive monitoring: Continuous ECG, SpO₂, NIBP; frequent RR, Temp, Pain assessment.
  • Discharge criteria: Modified Aldrete Score ≥9 (Components: Activity, Respiration, Circulation, Consciousness, O₂ Saturation).
• Common Immediate Post-Op Issues:
  • PONV (Nausea & Vomiting), acute pain, shivering.
  • Respiratory: Airway obstruction, hypoxemia, hypoventilation.
  • Cardiovascular: Hypotension, hypertension, arrhythmias.
• Anesthetic Records:
  • Accurate, chronological documentation: Pre-op assessment, intra-op (vitals, drugs, fluids, techniques, critical events), post-op condition & handover.
  • Crucial medico-legal document.

  ⭐ "If it wasn't documented, it wasn't done" - a key principle in medical jurisprudence regarding anesthetic records.

• Informed Consent: Valid, specific for procedure & anesthesia, documented pre-operatively.

High‑Yield Points - ⚡ Biggest Takeaways

• Comprehensive preoperative assessment and ASA status are vital for risk identification.
• Informed consent must clearly outline specific anesthesia risks and alternatives.
• Strict adherence to ASA standard monitoring (pulse oximetry, NIBP, ECG, capnography, temperature) is non-negotiable.
• Difficult airway algorithms (e.g., DAS guidelines) and immediate dantrolene access for MH are critical.
• Utilize the WHO Surgical Safety Checklist consistently to prevent errors like wrong-site surgery.
• Implement robust medication safety protocols: meticulous labeling, dose verification, and vigilance against look-alike sound-alike drugs.
• Foster closed-loop communication and regular simulation training for effective crisis resource management (CRM).
