Abstract

Background: Total knee arthroplasty represents one of the most popular orthopaedic surgeries, with over 500,000 treatments performed in the USA each year. Despite this similarity, there is no consensus on the appropriate strategy for delivering anesthetic as well as analgesia during arthroplasty surgeries. Objective:  This paper aims to analyse and evaluation of exploratory results of complications in knee arthroplasty when using the general anaesthesia technique. Patients and methods: This paper was presented as a cross-sectional study where it focused on analyse and evaluation of exploratory results of complications in knee arthroplasty when using a general anaesthesia technique that include 80 cases in Baghdad-Iraq from 23^rd September 2021 to 17^th July 2022. This data was designed with used two kinds of anaesthesia which, general and spinal, to investigate the impact of general anaesthesia on patients during operations as well as to analyse in performance of general anaesthesia in comparison with spinal anaesthesia through this study was divided data into two groups the first group has general anaesthesia with 40 cases and the second group has a spinal group with 40 where the data was designed and analysed by SPSS program. Discussion: most of those previous studies compared epidural with general anesthesia, and there have been few trials directly comparing spinal anesthesia with general anesthesia in patients managed with total knee arthroplasty. Thus, patients with multiple comorbidities are the most likely to benefit from general anesthesia, and this modality should strongly be considered for the patient with comorbidities. In the present study, age, sex, ASA class, operative time, and anesthetic choice were all independent risk factors for an increased thirty-day complication rate [Clarke, M.T. et al., 2001]. These results are consistent with previous studies showing that sex, spinal anesthesia, and older age are significant predictors of increased complication rates. Conclusions: In conclusion, our findings show that patients undergoing total knee arthroplasty under general anaesthesia had a much lower risk of problems than those using spinal anaesthesia. The huge number of patients in this trial offered enough power to detect very modest changes between groups. The observed variations in several cases were 7%, and the therapeutic significance of such a minor variance is unclear. As a result, it is critical to understand that the variations in the rate of complications comparing spinal and general anaesthesia are minor, indicating that general anaesthesia is still a viable option for many patients having total knee arthroplasty. The differences are highest in individuals with many medical comorbidities, suggesting that spinal anaesthetic may be more beneficial in this population
