Incidence: SSIs are among the most common complications, accounting for approximately 20% of all healthcare-associated infections.
Risks: Increased morbidity, prolonged hospital stays, additional surgical procedures, and, in severe cases, sepsis.
Hemorrhage (Bleeding)
Description: Excessive bleeding during or after surgery can lead to hypovolemia, shock, and organ dysfunction.
Incidence: Varies by procedure; major surgeries like cardiovascular or hepatic surgeries have higher bleeding risks.
Risks: Need for blood transfusions, reoperation, prolonged recovery, and in extreme cases, death.
Anesthesia-Related Complications
Description: Adverse reactions to anesthesia can range from mild side effects like nausea to severe outcomes such as respiratory depression or cardiac arrest.
Incidence: Anesthesia-related mortality is rare, approximately 1 in 100,000 to 200,000 cases, but less severe complications are more common.
Risks: Prolonged recovery, aspiration pneumonia, allergic reactions, and in severe cases, brain damage or death.
Blood Clots
Description: Deep vein thrombosis (DVT) and pulmonary embolism (PE) are serious complications where blood clots form in the veins, potentially traveling to the lungs.
Incidence: DVT occurs in 1-2% of general surgical patients and PE in 0.1-0.2%.
Risks: Chronic pain, post-thrombotic syndrome, sudden death due to PE.
Organ Damage
Description: Accidental injury to nearby organs or structures during surgery can occur, depending on the surgical site.
Incidence: Varies with surgical complexity; higher in procedures involving vital organs.
Risks: Functional impairment, chronic pain, additional surgeries, and permanent disability.
Delayed Healing and Scarring
Description: Poor wound healing or excessive scarring can result from inadequate surgical technique or patient factors.
Incidence: Approximately 10-15% of surgical patients may experience some degree of impaired healing.
Risks: Cosmetic concerns, restricted movement, increased pain, and risk of hernias.
Nerve Damage
Description: Inadvertent injury to nerves can lead to numbness, weakness, or chronic pain.
Incidence: Nerve injury occurs in about 1-2% of surgeries, depending on the procedure.
Risks: Persistent pain, loss of function, and reduced quality of life.
Postoperative Delirium and Cognitive Dysfunction
Description: Especially common in older adults, these conditions involve confusion, memory impairment, and decreased cognitive function post-surgery.
Incidence: Occurs in up to 50% of elderly patients undergoing major surgery.
Risks: Prolonged hospitalization, decreased independence, and increased mortality.
