目的:麻醉患者的术前风险分类是一项重要的研究,也是许多研究和分类的焦点。另一方面,理想的分类系统,根据医生的临床经验和与其他学科的合作,尚未开发。
方法:在本研究中,包括218例连续接受腹腔镜胆囊切除术的患者。建立了由270条规则组成的模糊逻辑评价模型。五个主要(肺,心脏,糖尿病和肾脏或肝脏疾病)和三个次要标准(患者年龄,选择吸烟和体重指数)用于确定高危人群。
结果:使用所提出的新颖模糊逻辑算法验证风险值决策的成功是本研究的主要目标。另一方面,虽然不是基本目标,还包括统计一致性检查,以更深入地理解和评估图形结果。在统计分析的0-30%,发现30-60%和60-90%的风险范围与并发症的发生呈非常强的正相关。在这项研究中,172、31、15例患者的风险范围为0-30、30-60和60-90%,分别。并发症发生率为7/172(4.07%),范围为0-30%,30-60%范围内的3/31(9.68%);60-90%范围内的2/15(13.33%)。
结论:基于Fuzzy的风险分类模型成功地用于预测腹腔镜胆囊切除术患者的医疗结果,并获得了可靠的推断。
OBJECTIVE: Pre-operative risk classification of patients undergoing anesthesia is an essential interest and has been the focus of many research and categorizations. On the other hand, the ideal categorization system, based on medical doctors\' clinical experience and cooperation with other disciplines, has not been developed yet.
METHODS: In this study, 218 consecutive patient undergoing laparoscopic cholecystectomy operations were included. A novel fuzzy logic evaluation model consisting of 270 rules was constructed. Five major (pulmonary, cardiac, diabetes mellitus and renal or liver disease) and three minor criteria (patients\' age, cigarette smoking and body mass index) were chosen to be used during high-risk groups determination.
RESULTS: The verification of the success of risk value decision with the proposed novel fuzzy logic algorithm is the main goal of this study. On the other hand, though not essential aim, a statistical consistency check was also included to have a deeper understanding and evaluation of the graphical results. During the statistical analysis the 0-30%, 30-60% and 60-90% risk ranges were found to be in a very strong positive relationship with complication occurrence. In this study, 172, 31, 15 patients were in 0-30, 30-60 and 60-90% risk ranges, respectively. Complication rates were 7/172 (4.07%) in 0-30% range, 3/31 (9.68%) in 30-60% range; and 2/15 (13.33%) in 60-90% range.
CONCLUSIONS: Fuzzy based risk classification model was successfully used to predict medical results for patients undergoing laparoscopic cholecystectomy operations and reliable deductions were reached.
