Randomized Controlled Trial Multicenter Study
[Multicenter, triple-blind randomized placebo controlled trial of adjuvant nitrous oxide 50% in oxygen 50%: efficacy for reducing pain and increasing satisfaction in patients treated for renal colic in the emergency department].
To assess the efficacy of a nitrous oxide and oxygen mixture (N2O/O2 50/50) for reducing pain and increasing satisfaction in patients with an initial clinical diagnosis of renal colic in the emergency department. ⋯ The addition of N2O/O2 50/50 to standard analgesic therapy does not enhance the efficacy of pain control or the satisfaction of patients treated for renal colic in the emergency department.
