Study Notes

Introduction

  • Preoperative evaluation helps the anesthesiologist understand the patient's overall health, including existing and past medical conditions.
  • This process is crucial for anticipating risks and optimizing patient care to ensure a safe anesthesia experience.

Purpose of Preoperative Evaluation

  • Identify patients needing specific medical treatment to improve outcomes.
  • Determine patients with specific characteristics that may influence the anesthetic plan.
  • Provide an opportunity for the anesthesiologist to explain the proposed anesthetic plan, offer psychological support, and obtain informed consent from the patient.

Components of Preoperative Evaluation

  • Thorough medical history and physical examination are vital.
  • This includes a comprehensive medication history, allergies, and previous anesthetic experiences.
  • The evaluation should include relevant diagnostic tests, imaging procedures, and consultations with other physicians.
  • Failure to thoroughly plan and prepare can lead to anesthetic complications.

History

  • The preoperative medical history should focus on:
    • Cardiac function
    • Pulmonary function
    • Kidney disease
    • Endocrine and metabolic diseases
    • Musculoskeletal issues
    • Anatomic features relevant to airway management and regional anesthesia
    • Prior responses and reactions to anesthetics

Physical Examination

  • The physical exam aims to detect any abnormalities that may not be apparent from the history.
  • Examination of healthy and asymptomatic patients includes:
    • Measuring vital signs (blood pressure, heart rate, respiratory rate, and temperature)
    • Examining the airway, heart, lungs, and musculoskeletal system using standard techniques.
  • Before procedures like nerve blocks, regional anesthesia, or invasive monitoring, the relevant anatomy should be carefully examined. The presence of infection or anatomical abnormalities may contraindicate the planned procedure.
  • Neurological examination is essential when regional anesthesia is anticipated.
  • Airway examination is mandatory before every anesthetic procedure.
  • Examine the patient's teeth for loose, chipped teeth, caps, bridges, or dentures.
  • Facial abnormalities like micrognathia, prominent upper incisors, a large tongue, limited temporomandibular joint or cervical spine range of motion, or a short or thick neck may indicate potential difficulty in direct laryngoscopy for tracheal intubation.

Preoperative Laboratory Testing

  • Routine laboratory testing is generally recommended for fit and asymptomatic patients.

Preoperative Evaluation

  • The anesthetist assesses the patient's general condition, medical history, and potential risks to ensure a safe and optimal anesthetic experience.
  • The evaluation aims to identify patients who require specific medical treatment before surgery.
  • The anesthetist also describes the proposed anesthetic plan, provides psychological support, and obtains informed consent from the patient.

Components of Preoperative Evaluation

  • Key components include a detailed medical history and physical examination.
  • The medical history encompasses all medications, allergies, and responses to previous anesthetics.
  • Diagnostic tests, imaging procedures, or consultations with other physicians may be necessary.

History

  • The preoperative medical history should emphasize:
    • Cardiac function
    • Pulmonary function
    • Kidney disease
    • Endocrine and metabolic diseases
    • Musculoskeletal issues
    • Anatomic issues relevant to airway management and regional anesthesia
    • Responses and reactions to previous anesthetics
    • Medication use

Physical Examination

  • The physical examination may reveal abnormalities not detected in the medical history.
  • The examination of healthy patients should include:
    • Measurement of vital signs (blood pressure, heart rate, respiratory rate, and temperature).
    • Examination of the airway, heart, lungs, and musculoskeletal system using standard techniques.
  • Before procedures like nerve blocks or regional anesthesia, the relevant anatomy should be examined for any contraindications (e.g., infection, anatomic abnormalities).
  • A neurological examination is important for patients undergoing regional anesthesia.
  • The anesthetist must examine the patient's airway before every anesthetic procedure, including inspecting for loose teeth, caps, bridges, or dentures.
  • Facial abnormalities, micrognathia, prominent upper incisors, large tongue, limited neck movement, or a short or thick neck might suggest difficulty in tracheal intubation.

Preoperative Laboratory Testing

  • Routine laboratory testing is recommended for fit and asymptomatic patients.
  • Testing should be guided by the patient's medical history and physical examination.

ASA Physical Status

  • The American Society of Anesthesiologists (ASA) classifies patients based on their physical status:
    • ASA 1: Healthy patient with no organic or psychiatric disease.
    • ASA 2: Patient with mild systemic disease, unlikely to impact anesthesia and surgery.
    • ASA 3: Significant or severe systemic disease that limits normal activity, likely to impact anesthesia and surgery.
    • ASA 4: Severe disease that is a constant threat to life, requiring intensive therapy.
    • ASA 5: Moribund patient with a high risk of death within 24 hours, regardless of surgery.
    • ASA 6: Brain-dead organ donor.
    • "E" added to the classifications indicates emergency surgery.
  • Informed consent is crucial and frequently questioned in malpractice cases.
  • It involves discussing the risks and benefits of the procedure, alternative options, and answering all patient questions.

Preoperative Evaluation

  • Anesthetists evaluate patients before surgery to understand their overall health, identify risks, and optimize their condition for a safe anesthetic experience.
  • Preoperative evaluation aims to identify patients who might benefit from specific medical treatments. It also helps determine how a patient's unique characteristics might influence their anesthesia plan.
  • The process includes a medical history review, physical examination, and potentially further diagnostic tests, imaging procedures, or consultations with other healthcare professionals.
  • A thorough medical history focuses on cardiac function, pulmonary function, kidney disease, endocrine and metabolic diseases, musculoskeletal issues, previous anesthetic responses, and medication use.
  • The physical examination should evaluate vital signs, airway, heart, lungs, and musculoskeletal system. Neurological examination is vital when regional anesthesia is planned.
  • The anesthetist should examine the patient's airway before every anesthetic procedure, noting features like loose teeth, dentures, facial abnormalities, or a short or thick neck that could impact laryngoscopy and tracheal intubation.

Preoperative Laboratory Testing

  • Routine laboratory testing is recommended for healthy, asymptomatic patients but should be tailored based on individual medical history and physical examination findings.

ASA Physical Status Classification

  • The American Society of Anesthesiologists (ASA) physical status classification categorizes patients based on their overall health and risk:
    • ASA 1: Healthy patient without any organic or psychiatric disease.

  • Pre-op evaluation aims to identify patients requiring specific treatments to optimize their outcomes.
  • Pre-op evaluation helps design an appropriate anesthetic plan based on individual patient characteristics.

Components of Preoperative Evaluation

  • The cornerstone of an effective evaluation is gathering a comprehensive medical history.
  • This includes a thorough account of current and past medications.
  • Patient's drug and contact allergies should be documented along with previous anesthetic responses or reactions.
  • Any required diagnostic tests, imaging procedures, or consultations should be included in the evaluation.
  • A detailed medical history and physical examination guide the anesthetic plan.

History Components

  • Vital information includes assessment of cardiac function, pulmonary function, kidney disease, endocrine and metabolic conditions, and musculoskeletal factors.
  • Relevant anatomical features for airway management and regional anesthesia are also crucial.
