Task: Question Generation
Input (English): The aim of this prospective, randomized, double-blind study was to compare two doses of intranasal sufentanil for postoperative analgesia, titrated according to individual requirements based upon a numeric rating scale (NRS) from 0 to 10 for pain.', 'Forty patients, American Society of Anesthesiologists physical status I-II, scheduled for herniorrhaphy or hemorrhoidectomy under general anesthesia, were included when postoperative NRS was > 3. Nurses used a nasal puff device delivering a constant volume. Patients were randomized into two groups: Group A patients received a dose of 0.025 microg x kg(-1) /puff, Group B patients a dose of 0.05 microg x kg(-1) /puff. Puffs were administered as often as needed to obtain NRS < or = 3, with an interval time of five minutes. Hemodynamic, respiratory measures and sedation were recorded every five minutes.', 'The probability of persistence of pain in Group B was consistently lower than in Group A. After 20 min, 20% of the patients had a NRS score > 3 in Group B, as opposed to 60% in Group A. At 60 min, no patient had a NRS > 3 in Group B, whereas there was a probability of 20% to record a NRS > 3 for Group A. Hemodynamic, respiratory parameters and sedation remained stable with no intergroup differences.
Output (English): Is intranasal sufentanil effective for postoperative analgesia in adults?
