Prediction of Difficult Airway-Ratio of Patient’s Height to Thyromental Distance
Journal Title: Journal of Medical Science And clinical Research - Year 2014, Vol 2, Issue 8
Abstract
Preoperative evaluation is important in the detection of patients at risk for difficult tracheal intubation. Thyromental distance (TMD) is often used for these purposes, The purpose of the present study was to evaluate and compare the accuracies of the ratio of patient’s height to TMD (ratio of height to TMD = RHTMD) in the prediction of difficult tracheal intubation. Four hundred patients were evaluated preoperatively using the TMD ,Modified Mallampati test(MP),and RHTMD. The three tests were compared analyzing the area under the receiver operating characteristic curves (AUC). Difficult laryngoscopy occurred in 13 patients (3.3%). The AUC of RHTMD was significantly greater (P<0.001) when compared to TMD, indicating a more accurate prediction by the RHTMD. RHTMD has shown to be highly specific(97.1%) and also sensitive(76.9%) with accuracy(96.5%) in predicting difficult intubation. The study is more sensitive and specific in comparison with MP. Based on our results, we recommend that the RHTMD should be used instead of the TMD.
