Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The primary endpoint was to compare the hemodynamic responses(defined as a change in heart rate or systolic blood pressure or both by more than 20% of their baseline values prior to induction of anaesthesia) between dexmedetomidine and placebo given in addition to the drugs used in our current standard of care during laryngoscopy and DLT insertion.Timepoint: At baseline(Prior to any drug administration), at laryngoscopy and double lumen tube insertion(Which effectively happen at the same time) and every minute after intubation for the first five minutes, then every five minutes until placement of tube is confirmed by fiber-optic bronchoscopy | — |
Secondary
| Measure | Time frame |
|---|---|
| To assess the incidence of hypotension and bradycardiaTimepoint: After study drug administration prior to induction of anaesthesia, 3 minutes after induction just before Double Lumen Tube insertion, at laryngoscopy and Double lumen tube insertion, and every minute after intubation for the first five minutes, then every five minutes until placement of tube is confirmed by fiber-optic bronchoscopy;To assess the intraoperative requirement of rescue medication (PNP, Ephedrine) to treat the hypotension and bradycardiaTimepoint: Immediately after study drug administration prior to induction of anaesthesia, 3 minutes after induction just before Double Lumen Tube insertion, at laryngoscopy and Double lumen tube insertion, and every minute after intubation for the first five minutes, then every five minutes until placement of tube is confirmed by fiber-optic bronchoscopy;To assess the requirement of additional anaesthetic drugs (fentanyl, propofol) in order to maintain the hemodynamics within 20% of baseline valuesTimepoint: During laryngoscopy and DLT insertion, and every minute after intubation for the first five minutes, then every five minutes until placement of tube is confirmed by fiber-optic bronchoscopy | — |
