After endotracheal extubation, patients were randomly divided into two groups.
The respiratory rate following endotracheal extubation was significantly lower at the 4th hour in patients who have received HFO (p < 0.001); however, it did not differ significantly at the other follow-up intervals.
The haemodynamic parameters of heart rate and blood pressure before and after endotracheal intubation, after the first surgical incision, 1 h after the start of the surgery and after endotracheal extubation
were similar in the two groups (no statistically significant differences).
Early endotracheal extubation
and fast tracking resulted in a 25% reduction of costs and a 15% increase in case volume while slightly decreasing complications6.
Blood pressure and pulse rate responses to endotracheal extubation
with and without prior injection of lidocaine.
(3) Dexmedetomidine an alpha 2 agonist have been successfully used for attenuating the sympathetic response during endotracheal extubation
. We conducted an observational study to examine the role of dexmedetomidine on hemodynamic response during endotracheal intubation.
Endotracheal extubation was carried out when patient was completely conscious and responded to verbal commands.
Table-3 shows that there was an abrupt rise in mean heart rate during and immediately after endotracheal extubation. The rise in mean HR was maximum in Group I as compared to Group II.
