Abstract
ObjectiveTo assess the accuracy of predicting difficult airway by Meta analysis of the modified Mallampati classification (MMP), the upper lip bite test (ULBT), thyromental distance (TMD), interincisor gap (IIG) .
MethodsThe Cormack and Lehnane's grading (CL) 3-4 and (or) intubation difficulty scale (IDS) >5 were taken as golden standards for diagnosis of difficult airway. Articles of predicting difficult airway by MMP, ULBT, TMD, and IIG published in English or Chinese from Jan 2003-Dec 2013 were collected. The sensitivity, specificity, summary receiver operating characteristic curves (SROC), area under the curve (AUC) and the heterogeneity were calculated with software of Meta-DiSc 1.4 and STATA 12.0.
ResultsTwenty-five articles were got into the standard. The diagnostic odds ratio (DOR) of ULBT was 19.83 (9.29-42.31). The AUC and Q* of ULBT were 0.900 4 and 0.831 6 respectively.
ConclusionsAmong MMP, ULBT, TMD, and IIG, the ULBT is a higher accuracy predictive method for detecting and judging difficult airway.
