Preoperative Evaluation And Preparation


The preoperative evaluation and preparation of patients is a crucial step in ensuring safe and successful surgical outcomes. This process involves a comprehensive assessment of the patient's medical history, physical examination, and necessary investigations to identify and manage any potential risks or complications associated with surgery. This article aims to provide an informative guide on the preoperative evaluation and preparation process.

Key Points

  1. Patient Assessment

    • Obtain a detailed medical history, including previous surgeries, allergies, chronic medical conditions, and current medications.
    • Perform a thorough physical examination, paying attention to cardiovascular, respiratory, and neurological systems.
    • Assess the patient's functional status and any limitations in daily activities that may affect their perioperative care.
  2. Cardiovascular Evaluation

    • Determine the patient's cardiac risk factors and evaluate for any underlying cardiovascular disease.
    • Consider obtaining an electrocardiogram (ECG) in patients with a history of cardiac disease or significant risk factors.
    • Assess the need for further cardiac investigations, such as echocardiography or stress testing, based on the patient's clinical presentation and surgical procedure.
  3. Respiratory Evaluation

    • Evaluate the patient's respiratory status, particularly in those with a history of smoking, chronic lung disease, or obstructive sleep apnea.
    • Consider pulmonary function tests or arterial blood gas analysis if indicated.
    • Optimize respiratory function through smoking cessation, bronchodilator therapy, and pulmonary rehabilitation when appropriate.
  4. Laboratory Investigations

    • Order routine laboratory tests, including complete blood count, coagulation profile, electrolytes, renal and liver function tests, and urinalysis.
    • Consider additional investigations based on the patient's medical history, such as blood glucose, thyroid function tests, and infectious disease screening.
  5. Medication Management

    • Review the patient's current medications and determine if any adjustments or temporary discontinuations are necessary.
    • Consider the use of prophylactic antibiotics, deep vein thrombosis prophylaxis, or other medications based on the surgical procedure and patient-specific risk factors.
  6. Nutritional Assessment

    • Assess the patient's nutritional status, particularly in those with malnutrition or obesity.
    • Consider consultation with a registered dietitian for optimization of nutritional support before and after surgery.
  7. Anesthetic Evaluation

    • Collaborate with an anesthesiologist to assess the patient's suitability for anesthesia and determine the appropriate anesthetic plan.
    • Evaluate the patient's airway, respiratory, and cardiovascular status to anticipate any potential intraoperative complications.
  8. Patient Education and Informed Consent

    • Provide detailed information about the planned surgical procedure, including potential risks, benefits, and alternatives.
    • Address any concerns or questions the patient may have regarding their surgery, anesthesia, or postoperative care.
    • Obtain informed consent after ensuring the patient fully understands the procedure and its implications.


The preoperative evaluation and preparation process is essential for ensuring patient safety and optimizing surgical outcomes. By carefully assessing the patient's medical history, performing necessary investigations, and collaborating with the surgical team, healthcare professionals can identify and manage potential risks, leading to improved perioperative care.
