Design outcomes

Primary

MeasureTime frame
This study showed that for study group (Entonox) the overall mean for pre-treatment Visual analogue scale (VAS) score were 6.5 and the overall mean for post-treatment VAS score was 2; for control group (fentanyl) overall mean for pre-treatment VAS score was 7.0 and the overall mean for post-treatment VAS score was 1.0. Timepoint: The mean time taken to initiate the therapy was 45 seconds in study group where as control group took 4.8 minutes. No patients had hemodynamic instability or respiratory arrest with entonox where as 17.5% of patients had hemodynamic instability and 7.5% of the patients had respiratory arrest and requiring definitive airway placement and temporary ventilatory support for 30 -45 minutes in fentanyl group. Post procedure observation period in emergency room was 20 minutes in entonox group where as it was 2 hours for fentanyl group.
