Tracheal intubation with Macintosh laryngoscope (MAC) might result in severe cardiovascular
com pi ications. Thc results of conducted studies investigating the effects of videolaryngoscopies on
hemodynamic response of tracheal intubation are cont1icting. We know little about the effects of videolaryngoscopies
on cardiac output changes during tracheal intubation. We compared cardiac output (COP)
and hcmodynamic responses in normal blood pressure (n=60) and hypertensive patients (n=60) among 3
intubation devices: the MAC, the UE videolaryngoscopy ® (UE). and the UE video intubation stylet ®
(VS). Cardiac index (CI). stroke volume index (SVI), heart rate (HR), systolic blood pressure (SBP) and
diastolic blood pressure (DBP) were recorded using LidcoRapid V2® preinduction, preintubation, and
eery minute for the first 5 min after intubation. We assessed oropharyngeal and laryngeal structures
injury as cli. Intubation time as significantly shorter than MAC groups (P |
