Concept
Perioperative mortality
Summary
Perioperative mortality has been defined as any death, regardless of cause, occurring within 30 days after surgery in or out of the hospital. Globally, 4.2 million people are estimated to die within 30 days of surgery each year. An important consideration in the decision to perform any surgical procedure is to weigh the benefits against the risks. Anesthesiologists and surgeons employ various methods in assessing whether a patient is in optimal condition from a medical standpoint prior to undertaking surgery, and various statistical tools are available. ASA score is the most well known of these.
Immediate complications during the surgical procedure, e.g. bleeding or perforation of organs may have lethal sequelae.
Hospital-acquired infection
Countries with a low human development index (HDI) carry a disproportionately greater burden of surgical site infections (SSI) than countries with a middle or high HDI and might have higher rates of antibiotic resistance. In view of the World Health Organization (WHO) recommendations on SSI prevention that highlight the absence of high-quality interventional research, urgent, pragmatic, randomised trials based in LMICs are needed to assess measures aiming to reduce this preventable complication.
Local infection of the operative field is prevented by using sterile technique, and prophylactic antibiotics are often given in abdominal surgery or patients known to have a heart defect or mechanical heart valves that are at risk of developing endocarditis.
Methods to decrease surgical site infections in spine surgery include the application of antiseptic skin preparation (a.g. Chlorhexidine gluconate in alcohol which is twice as effective as any other antiseptic for reducing the risk of infection), use of surgical drains, prophylactic antibiotics, and vancomycin. Preventative antibiotics may also be effective.
Whether any specific dressing has an effect on the risk of surgical site infection of a wound that has been sutured closed is unclear.
