Background:Orthopaedic surgery is an operation conducted by a trained orthopaedic surgeon or orthopaedist expert to address musculoskeletal issues affecting the bones, chronic conditions, trauma, and ligaments from accidents, tendons, and joints. This study was conducted to assess thrombotic and bleeding complications following orthopaedic surgery.Material and methods: This study comprised of 100 subjects who underwent orthopaedic surgery. Major bleeding was defined as bleeding in a critical site, bleeding that resulted in either a 2 g/dl or greater decrease in haemoglobin during any 24-h period, or transfusion of two or more units of packed red blood cells. Results: In this study, 27 (27%) out of 100 patients showed ≥2 g/dl decrease in haemoglobin during 24-hour period following orthopaedic surgery. Out of 100 subjects, 49 were males and 51 were females. Deep vein thrombosis was seen in 9 subjects and pulmonary embolism was discovered in 4 subjects. Thrombotic complications were seen in overall 13 subjects. Bleeding complications were seen in 14 subjects including surgical site haemorrhage visible in 8 subjects and hematoma formation evident in 6 subjects.Conclusion: Thrombotic complications like pulmonary embolism and deep vein thrombosis were seen in a few subjects while bleeding complications like surgical site haemorrhage and hematoma formation was seen in other subjects following orthopaedic surgery.
