Medical Conditions the increase the risk of Surgery


Type of Condition Reason for Risk
Bleeding disorders (thrombocytopenia, hemophilia) Increase risk of hemorrhaging during and after Sx
Diabetes mellitus Increases susceptibility to infection and may impair wound healing from altered glucose metabolism and associated circulatory impairment.Stress of surgery may cause increases in blood glucose levels.
Heart Disease (recent myocardial infarction, dysrrhythmias, congestive heart failure) and peripheral vascular disease Stress of surgery causes increased demands on myocardium to maintain cardiac output.General anaesthetics depress cardiac function.
Obstructive sleep apnea Administration of opioids increases risk of airway obstruction post-operatively.Patients will desaturate – drop in pulse oxymetry reading
Upper respiratory infection Increases risk of respiratory complications during anesthesia (pneumonia and laryngeal muscle spasm)
Liver disease Alters metabolism and elimination of drugs administered during surgery and impairs wound healing and clotting time because of alterations in protein metabolism
Fever Predisposes patient to fluid and electrolyte imbalances and may indicate underlying infection.
Chronic respiratory disease (emphysema, bronchitis, asthma) Reduces client`s ability to compensate for acid-base alterations.Anesthetics depress respiratory function and increase risk of hypoventilation.
Immunoligical disorders (leukemia, AIDS, immunosupressants, chemo drugs) Increases risk of infection and delayed wound healing after surgery.
Abuse of street drugs Individuals may have underlying disease (hepatitis or HIV) which affects healing
Chronic pain Regular use of pain medications may result in higher tolerance.Increased doses of analgesic may be required to achieve post-operative pain control.
