Surgical Risk Factors

Flashcards
0/30
Thyroid Dysfunction
Both hypothyroidism and hyperthyroidism can lead to significant metabolic complications, impact cardiovascular stability, and influence the response to anesthetic drugs.
Renal Insufficiency
Impaired kidney function can lead to difficulties in fluid and electrolyte balance, increased risk of postoperative kidney injury, and problems with medication elimination.
Obstructive Sleep Apnea (OSA)
OSA increases the risk of postoperative respiratory complications, including hypoxemia and airway obstruction, and may affect pain management due to opiate sensitivity.
Age
Older patients often have a higher risk of surgical complications due to a general decline in physiological reserves and potential presence of comorbid conditions.
Previous Surgical History
Previous operations, especially in the same area, can increase the risk of adhesions and technical difficulties during repeat surgeries.
Hypertension
Uncontrolled high blood pressure can increase the risk of bleeding, cardiac events, and stroke during surgery, and can impact the choice and management of anesthesia.
Coagulation Disorders
Abnormal blood clotting can lead to increased risk of bleeding or thrombosis, affecting surgical technique and necessitating careful postoperative monitoring.
Preoperative Anemia
Anemia can lead to decreased oxygen carrying capacity, resulting in increased risk of perioperative morbidity, and necessitates careful consideration regarding blood transfusions.
Electrolyte Imbalance
Abnormal electrolyte levels can cause complications such as cardiac arrhythmias and neurological disturbances, affecting perioperative management and recovery.
Performance Status
A patient's physical fitness and ability to carry out daily activities affects their risk for surgery and can predict the likelihood of postoperative complications and recovery.
Medication Use
Certain medications, like antiplatelets or anticoagulants, increase the risk of perioperative bleeding, while others can interact with anesthetic agents.
Smoking
Smoking can impair wound healing, increase the risk of respiratory complications, and negatively impact cardiovascular health, leading to a higher risk of complications during and after surgery.
Obesity
Obesity increases surgical risk through associated comorbidities like cardiovascular disease, diabetes, and an increased likelihood of postoperative complications (e.g., infections, wound healing problems).
Liver Disease
Liver dysfunction can alter the metabolism of drugs, affect coagulation, and lead to an increased risk of bleeding and postoperative liver decompensation.
Alcohol Abuse
Chronic alcohol consumption can lead to liver dysfunction, increased bleeding risks, and can cause withdrawal symptoms postoperatively, complicating recovery.
Goldman Cardiac Risk Index
This is a scoring system used to estimate the risk of cardiac complications after surgery based on factors like age, history of MI, and type of surgery.
Chronic Steroid Use
Long-term steroid use can impact immune function, wound healing, and blood sugar control, possibly increasing the risk of infection and other complications.
Cardiovascular Disease
Patients with cardiovascular disease are at a higher risk for cardiac events during and after surgery, and may experience difficulties with anesthesia and fluid management.
Pulmonary Disease
Pre-existing lung conditions such as COPD can increase the risk of respiratory failure, pneumonia, and prolonged mechanical ventilation post surgery.
Immunosuppression
Immunocompromised patients have an increased risk of infections and may have a delayed healing process due to a weakened immune system.
Anesthetic History
A history of adverse reactions to anesthesia can increase the risk of complications and influences the choice of anesthetic technique and agents for future surgeries.
Nutritional Deficiencies
Deficiencies in essential nutrients can impair tissue repair, immune response, and contribute to a higher susceptibility to infection.
Autoimmune Diseases
Autoimmune conditions may necessitate special perioperative management, increase the risk of infection, and affect wound healing due to immune dysregulation.
Psychological Factors
Stress, anxiety, and depression can affect recovery, compliance with postoperative care, and the overall surgery experience.
BMI Extreme (Underweight or Morbidly Obese)
Both extremes of BMI can increase surgical risk due to potential nutritional status issues, dosing challenges with medication and anesthesia, and increased difficulty in surgical technique.
Family History of Surgical Complications
A known family history of complications such as malignant hyperthermia can increase the risk of similar reactions and should guide anesthetic choices.
Infectious Status (MRSA, VRE, etc.)
Patients carrying or infected with multi-drug resistant organisms (MDROs) like MRSA or VRE have a higher risk of postoperative infections and may require isolation and additional precautions.
History of Deep Vein Thrombosis or Pulmonary Embolism
Patients with a history of DVT or PE are at increased risk for recurrence and may require specific prophylactic measures to prevent thrombotic events around the time of surgery.
Malnutrition
Poor nutritional status can weaken immune response, impair wound healing, and increase the risk of infection, all of which can negatively influence surgical outcomes.
Diabetes Mellitus
Diabetes increases the risk of infection, may lead to poorer wound healing, and can complicate the management of blood glucose levels around the time of surgery.
