Comparison of the effects of Truview PCD™ video laryngoscopy and Macintosh blade direct laryngoscopy in geriatric patients

Comparison of the effects of Truview PCD™ video laryngoscopy and Macintosh blade direct laryngoscopy in geriatric patients

Journal of Clinical Anesthesia 35: 268-273

To compare the effects of Truview PCD™ video laryngoscopy (TVL) and Macintosh blade direct laryngoscopy (MDL) on hemodynamic responses observed during laryngoscopy and orotracheal intubation conditions in geriatric patients. Randomized prospective study. Operating room. One hundred patients in the risk group American Society of Anesthesiologists I to III aged 65 years and older underwent elective surgery under general anesthesia. This prospective study was performed between January 2014 and February 2015 after institutional ethics committee approval. Patients were randomly allocated to 2 groups, namely, TVL and MDL. Hemodynamic parameters, modified Cormack-Lehane grade, intubation period, and preoperative examination (age, sex, American Society of Anesthesiologists, modified Mallampati test score, and thyromental and sternomental distances) of patients were evaluated. There were no statistically significant differences in hemodynamic responses (heart rates and mean arterial pressure) between the 2 groups (P>.05). The median intubation period in the TVL group was significantly higher than observed in the MDL group (t=4.594; P<.05). The laryngoscopy views in TVL group were better than the views in MDL group. The Cormack-Lehane grade in the TVL group was lower when compared to the MDL group. The TVL system does not provide significant hemodynamic response sparing or shorten orotracheal intubation times when compared to MDL in geriatric patients.
