Objective

This study was performed to determine the risk factors associated with postoperative complications after surgery under general anesthesia according to respiratory function test results and oral conditions.

Materials and methods

Preoperative examination data were collected for 471 patients who underwent surgery under general anesthesia at the Medical Hospital of Kyusyu University. Respiratory function tests, oral examinations, and perioperative oral management were performed in all patients. The incidence of and risk factors for postoperative complications were investigated. Classification and regression tree analyses were performed to investigate the risk factors for postoperative complications.

Results

Among the 471 patients, 11 developed postoperative pneumonia, 10 developed postoperative respiratory symptoms, and 10 developed postoperative fever. The most important risk factor for pneumonia was edentulism. Age, the Brinkman index, and head and neck surgery were also revealed as important risk factors for pneumonia. The O’Leary plaque control record (initial visit) was an important risk factor for postoperative respiratory symptoms. With respect to postoperative fever, a Hugh–Jones classification of grade > 1 was the most important risk factor; edentulism and a Brinkman index of > 642.5 were also found to be risk factors.

Conclusion

In addition to respiratory function tests, oral examinations may be important for the prediction of postoperative complications. Additionally, improved oral hygiene may be effective in preventing postoperative respiratory complications.

Clinical relevance

Risk factors for postoperative complications should be comprehensively evaluated using both respiratory function tests and oral findings.

根据全身麻醉前术前检查发现,术后发生肺炎的危险因素。

目的

这项研究旨在根据呼吸功能测试结果和口腔状况确定在全身麻醉下手术后并发症的危险因素。

材料和方法

在九州大学医学院附属医院接受全麻手术的471例患者的术前检查数据。所有患者均进行了呼吸功能测试,口腔检查和围手术期口腔处理。研究了术后并发症的发生率和危险因素。进行分类和回归树分析以调查术后并发症的危险因素。

结果

在这471例患者中,有11例发生了术后肺炎,10例出现了术后呼吸道症状,10例出现了术后发烧。肺炎的最重要危险因素是无牙菌病。年龄,Brinkman指数和头颈部手术也被认为是肺炎的重要危险因素。O'Leary斑块控制记录(首次就诊)是术后呼吸道症状的重要危险因素。对于术后发烧,最重要的危险因素是Hugh-Jones分类> 1级。牙痛和Brinkman指数> 642.5也是危险因素。

结论

除呼吸功能检查外,口腔检查对于预测术后并发症可能也很重要。此外,改善口腔卫生可能对预防术后呼吸系统并发症有效。

临床相关性

术后并发症的危险因素应通过呼吸功能检查和口腔检查综合评估。
