Perioperative cardiology: an inspiring arena for the Chameleon doctor

摘要

The estimated annual global volume of surgical procedures increased by 38% between 2005 and 2012, reaching 312.9 million. Taking into account both the world population of seven billion and the average life expectancy of 71 years, one can easily estimate that each individual would undergo surgery 3.2 times in a lifetime.3 Some surgeries are quite simple, but others are associated with an increased risk of complications and require more intensive care, including major surgeries or interventions in patients with comorbidities.4 Each intervention has its own risk of complications, depending on important constraints that are shown in figure 1.
