| description | Context: Rigid bronchoscopy (RB) procedures require continuous vigilance and monitoring. Such procedures warrant proper ventilation strategy and titration of potent short-acting anesthetics.
Aims: To compare propofol with the propofol-dexmedetomidine in conjunction with topical airway anesthesia in two groups during spontaneous assisted ventilation on peri-procedural hemodynamic stability.
Settings and Design: This prospective, randomized, double-blinded study was done on 40 patients who were randomized in two groups, 20 patients in each group; PS (Propofol+ Normal saline) and PD (Propofol+ Dexmedetomidine) group. All patients in both groups were induced with 1' IV propofol (1–3 mg/kg), IV midazolam (0.05 mg/kg), and IV fentanyl (2 μ/kg). PS group received propofol infusion for maintenance along with saline infusion 10 min before induction, whereas PD group also received propofol infusion for maintenance along with Injection dexmedetomidine infusion 10 min before induction. Outcome measured were heart rate (HR), mean blood pressure (MBP), oxygen saturation (SpO2), and post-procedure awakening using Modified Observer's Assessment of Alertness/Sedation (MOAAS) scale and complications.
Results: In both the groups, MBP decreased significantly from baseline, however, when MBP were compared at the same time points between the groups there were no significant differences. In PD group, HR remained significantly lower when compared with baseline and at 6, 12, 18, and 24 min time points when compared with PS group. Number of patients who developed hypotension requiring vasoactive drugs, their mean dose and duration of hypotension were more in PD group, and they awoke with significant delay.
Conclusions: Propofol is better than combination of propofol and dexmedetomidine when given in adjunct with topical airway anesthesia for RB in view of early awakening, lesser duration of intra-procedural hypotension, and lesser requirement of vasoactive agents. |
