Although uncommon, local anaesthetic systemic toxicity (LAST) may impose fatal risk to the patients. We investigated the awareness of LAST and knowledge on local anaesthetics among our postgraduate trainees.
A total of 134 postgraduate trainees from the departments of general surgery (Surgical), orthopaedic surgery (Ortho), otorhinolaryngology (ENT), obstetrics and gynaecology (OBGYN), as well as anaesthesiology and intensive care (Anaesth) were recruited. A validated questionnaire was used to assess awareness and knowledge. All participants attended a medical-education session and completed the questionnaire as preassessment and postassessment. Data were analysed, and comparisons between disciplines were conducted.
The trainees' awareness of LAST was overall poor at preassessment which improved almost 6-folds at postassessment. Surprisingly, only 20 (45.5%) participants from the anaesthesiology group had awareness of LAST at preassessment, and none of the participants were from surgical, orthopaedic, and obstetrics and gynaecology departments. Preassessment scores were significantly higher in the anaesth group as compared to all other groups; with a difference in the average score for Anaesth vs Surgical of 3.46 (95%, CI:2.17, 4.74), Anaesth vs Ortho of 3.64 (95%, CI:2.64, 4.64), Anaesth vs ENT of 3.43 (95%, CI:2.20, 4.67), and Anaesth vs OBGYN of 6.93 (95%, CI:5.64, 8.21). However, there was no significant difference of awareness scores between all participants at postassessment scores.
The overall level of awareness was poor. However, the implementation of an education session significantly improved the knowledge and awareness across all disciplines.
局部麻醉全身毒性（LAST）虽不常见，但可能对患者造成致命风险。我们调查了研究生学员对 LAST 的认识和对局部麻醉剂的了解。
共招募了来自普通外科（外科）、矫形外科（矫形）、耳鼻喉科（耳鼻喉科）、妇产科（妇产科）以及麻醉学和重症监护（麻醉）的 134 名研究生学员。使用经过验证的问卷评估意识和知识。所有参与者都参加了医学教育课程，并在预评估和后评估时完成了问卷。对数据进行分析，并对不同学科进行比较。
学员对 LAST 的认识在预评估时整体较差，在评估后几乎提高了 6 倍。令人惊讶的是，只有 20 名（45.5%）麻醉组学员在预评估时对 LAST 有认识，而且没有一个学员来自外科、矫形外科和妇产科。预评估分数在麻醉组中明显高于其他所有组；麻醉组与外科组的平均分数差异为 3.46（95%CI：2.17，4.74），麻醉组与矫形组的平均分数差异为 3.64（95%CI：2.64，4.64），麻醉组与耳鼻喉科组的平均分数差异为 3.43（95%CI：2.20，4.67），麻醉组与妇产科组的平均分数差异为 6.93（95%CI：5.64，8.21）。然而，在后评估中，所有参与者的意识评分没有显著差异。
总体意识水平较差。然而，实施教育课程显著提高了所有学科的知识和意识。
