The number of patients who underwent spine surgery tends to increase every year. The rate of spine surgery in the United States is approximately 900,000 cases per year, and the age of the patients tends to be higher. A Japanese study found age 54.6 years in 2004 to 63.7 years in 2015, mainly were degenerative spine surgery. Spine surgery is likely to have a lot of blood loss during surgery and taking a long time for the operation. Most elderly patients are predisposing to the occurrence of cardi

Inclusion criteria
Inclusion criteria: After approval by the Research Ethics Committee of the Neurological Institute of Thailand, a retrospective cohort study was done. The data was collected from patients who underwent spine surgery in single hospital, Neurological Institute of Thailand. The sample size was calculated from the estimating an infinite population proportion with n4studies software (Ngamjaras C. et al., The Thailand Research Fund, Prince of Songkla University, Songkla, Thailand, 2016). The incidence of cardiovascular complications after anesthesia in elderly patients undergoing orthopedic surgery was 2.3% based on the research of Chalacheewa and colleagues with the configuration of error (d) was 0.019. After substituting the values in the calculation formula, a sufficient sample is 863 patients plus a drop out of 20%. The final sample was 1,035 patients. Data were collected within two years, from January 2018 to December 2019, using all inpatient medical records and an electronic anesthesia recording system. Patient datas were demographics including American Society of Anesthesiologists (ASA) physical status classification, laboratory finding, surgical data, and anesthesia-related, e.g., intraoperative blood pressure, amount of blood loss. Cardiovascular complications were defined following the definition of Major adverse cardiovascular events (MACEs) that occur during perioperative and within 30 days postoperative period including cardiac arrest, acute congestive heart failure (acute CHF), acute myocardial infarction (acute MI), and acute stroke.
