Randomized Controlled Trial Comparative Study
Comparison of high-flow nasal cannula oxygen therapy and conventional reserve-bag oxygen therapy in carbon monoxide intoxication: A pilot study.
High-flow nasal cannula oxygen (HFNC) creates a positive pressure effect through high-flow rates compared to conventional oxygen therapy. The purpose of this human pilot study is to compare the effects of HFNC and conventional oxygen therapy on the rate of carbon monoxide (CO) clearance from the blood in patients with mild to moderate CO poisoning. ⋯ In this pilot randomized controlled trial study, HFNC therapy did not reduce fCOHbt1/2 compared to NBO2 therapy but could be beneficial in maintaining a constant fCOHbt1/2 as well as in reducing fCOHbt1/2 in mild CO poisoning patients compared to conventional NBO2 therapy. However, further studies with a larger number of patients are needed to establish HFNC therapy as an alternative therapy for CO poisoning patients.

Randomized Controlled Trial Comparative Study
Atomized intranasal vs intravenous fentanyl in severe renal colic pain management: A randomized single-blinded clinical trial.
Renal colic is one of the most common painful disorders in patients referred to the emergency department. The main purpose of this study was to compare the efficiency of two methods of intravenous (IVF) and intranasal (INF) fentanyl administration in pain management in patients with severe renal colic. ⋯ Fentanyl is highly effective in controlling pain in patients with severe renal colic referring to the emergency department. Intranasal administration of fentanyl combination with ketorolac can be an appropriate, non-invasive, easy-to-use and fast alternative to the intravenous method to manage pain in these patients.
