Prewarming of the i-gel facilitates successful insertion and ventilation efficacy with muscle relaxation: a randomized study

Cricoid pressure impedes tracheal intubation with the Pentax-AWS Airwayscope®: a prospective randomized trial

“…The VAS score for laryngoscopy did not significantly differ between the groups (sham group: 20 [10][11][12][13][14][15][16][17][18][19][20] mm, CP group: 20 mm; P=0.06, 95% CI for median difference 1-18 mm). The VAS score for passage of a tube through the glottis was significantly lower in the sham group than in the CP group (sham group: 13 mm, CP group: 60 [40-70] mm; P<0.001, 95% CI for median difference 20-43 mm; Table 2).…”

“…12 Routine monitoring including non-invasive bp, heart rate, electrocardiography, percutaneous oxygen saturation, EEG using the Bispectral Index ® (BIS), and end-tidal carbon dioxide tension was performed. 13 Without any premedication, anaesthesia was induced with propofol 1-2 mg kg −1 and remifentanil 0.3-0.5 μg kg −1 min −1 , and neuromuscular block was achieved with rocuronium 0.9 mg kg −1 . The doses of propofol and remifentanil were determined by anaesthetists on the basis of the patient's age or condition.…”

Comparison of McGRATH MAC and Macintosh laryngoscopes for double-lumen endotracheal tube intubation by anesthesia residents: a prospective randomized clinical trial

“…The χ 2 test was used to assess the number of intubation attempts, Cormack classification, pharyngeal pain, and hoarseness. The Mann-Whitney U test was used to assess intubation time, POGO score, and VAS for laryngoscopy and tube passage through the glottis [9]. Data are presented as mean ± SD.…”

LMA-ProSeal insertion by novice doctors as affected by a 90° bend created by an intubating stylet: a randomized clinical trial

“…Data are presented as mean ± SD, unless otherwise indicated. P b .01 was considered statistically significant [13].…”
