Perioperative nonanesthetic complications in cesarean delivery in New York state between 2003 and 2012. The P value is from a multivariate logistic regression adjusted for year and Charlson and Bateman comorbidities indexes.^17–19  The legend indicates the percent change from 2003 to 2012 (95% CI). NA indicates that the percent change for these adverse events cannot be accurately calculated because of the absence or low number of events in 2003. (A) Crude rate of nonanesthetic perioperative complications. Complications include at least one of the following events: acute myocardial infarction or ischemia, acute right or left heart failure, acute respiratory failure, blood-clot pulmonary embolism or deep venous thrombosis, disseminated intravascular coagulation, acute renal failure, sepsis or septic shock, and stroke. The vertical lines indicate the exact 95% CI. The subscript numbers indicate the number of events for the corresponding year. (B) Crude rate of specific perioperative complications. The temporal trends are statistically significant (all P < 0.05) for all the complications presented in the figure. A decrease was observed for two complications: venous thromboembolic disease and stroke. DIC = disseminated intravascular coagulation; VTE = venous thromboembolic disease.
