Assessment of Perioperative Risk Factors; Medical Disorders, ASA Classifications, MRC Scale, Smoking and Opium Habit among Elderly Patients for Elective Surgery: Tehran-Iran

Background: Background: Elderly patients are more likely to require surgery and are at greater risk for surgical complications than young age group. The causal factors include decreasing physiologic reserve and increasing number of underlying health check problems. The aim of the current study is to evaluate preoperatively common medical disorders and habits as risk factors among elderly patients. Method: The protocol of study was finalized with an interview and was completed in several standard screening questionnaires. Results: A total of 155 subjects completed the criteria of study. Mean age was recorded 69.8±5.7 SD years (female: 52%, male: 48%). Frequency of smoking habit, opium using and alcohol drinking was 42 %( male; 53%), 15% (male; 85%) and 5%. Common disorders included respiratory (36%), cardiovascular (31%), diabetes mellitus (11%), renal (7%) and cerebrovascular (5%). Frequency of perioperative mortality risk of elderly patients occupied ASA classifications, including; classes=III 33% and IV =37%, respectively. The significant differences were seen between ASA classifications and MRC scale (? < 0.001). However, meaningful differences were found between gender and opium using (? < 0.001, odd ratio=7.6). Conclusion: Our finding indicated that mortality rate of perioperative risk was considerably based upon ASA physical status classification among elderly Iranians. It may be due to significant prevalence of respiratory and cardiovascular diseases, and also additionally present hazardous habits as smoking and opium using among aged patients. Surgical team should be awarded respect to social habits and frequency of disorders among the old-age population.
