Abstract

Since the two educational centers of Imam Reza and Shohada affiliated to Tabriz University of Medical Sciences have the highest number of orthopedic lower limb surgeries and also the possibility of increasing DVT in people with a history of cardiovascular disease and lack of accurate information about the effect of type Anesthesia method In the occurrence of this dangerous complication, we decided to conduct the present study with the aim of comparing the prevalence of deep vein thrombosis following lower limb surgery in both general anesthesia and spinal anesthesia in people with a history of cardiovascular disease. Materials and Methods: This cross-sectional descriptive study was performed in Imam Reza Hospital in Tabriz in 1399 with the participation of 100 patients undergoing limb surgery. Patients underwent surgery using one of the general or spinal anesthesia methods, according to the entry and exit criteria. The questionnaire was completed for all individuals after surgery, and high-risk individuals were referred for additional diagnoses such as the dimer test and Doppler ultrasound. The results were analyzed by Chi-square statistical tests, accurate Fisher's independent test with a significance level of less than five percent in SPSS software. Results: The incidence of DVT clinical symptoms in patients receiving general anesthesia was 17.14% and in patients receiving spinal anesthesia was 22.85%. General anesthesia was (P = 0.103); However, the prevalence of this complication after Doppler ultrasound was zero in both groups
