Background: Cardiovascular hemodynamic changes after laryngoscopy and endotracheal intubations can cause serious complications. This study was carried out to evaluate the correlation between the anthropometric indices and hemodynamic changes after laryngoscopy and endotracheal intubation (EI). Materials and Methods: This descriptive–analytical pilot study was carried out in 2012, in the Kashani Hospital, Isfahan, Iran. After obtaining written informed consent from 130 patients who fulfilled the inclusion criteria, they were enrolled in the study. The recorded data included were, age, weight, height, neck circumference (NC), waist-to-hip ratio (W/H ratio) and body mass index (BMI). The heart rate (HR), systolic blood pressure (SAP), diastolic blood pressure (DBP), and mean arterial blood pressure (MAP) were recorded at baseline (before injection of the anesthetic drugs), just before laryngoscopy, and one, three, five, and ten minutes after EI. Results: The best cut-off points for BMI, NC, and W/H ratio, for prediction of significant cardiovascular changes after EI were, 26.56 kg/m2, 38 cm, and 0.82, respectively. There was a significant correlation between BMI and HR changes in the first and fifth minutes and also in MAP in the third and fifth minutes after EI (P < 0.05). Moreover, there was a significant correlation between NC and MAP in the fifth minute (P < 0.05). The W/H ratio was significantly related to the DBP in the tenth minute and MAP in the fifth and tenth minutes (P < 0.05). Conclusions: Based on the results of this study, among the anthropometric indices, the BMI, NC, and W/H ratio were significantly correlated with cardiovascular changes after laryngoscopy and tracheal intubation.
