dc.description.abstractIn the present study, the purpose was to investigate the effect of oxygen therapy applied with a double nasal cannula on desaturation and respiratory complications in cases planned for gastrointestinal endoscopy. A total of 300 patients with ASA I-II, between the ages of 18-65, who were scheduled to undergo gastrointestinal endoscopy, were included in the study. Following routine monitoring, the patients were randomized into 3 groups using the envelope method. Group TK5 (n=100) was administered 5 liters/minute (L/min) preoxygenation with a nasal oxygen cannula for 5 minutes during the procedure and afterwards, 5 L/min oxygen in the same manner. Group TK15 (n=100) was administered 15 L/min preoxygenation with a nasal oxygen cannula for 5 minutes during the procedure and afterwards, 15 L/min oxygen in the same manner. Group CK30 (n=100): 30 L/min preoxygenation with a double nasal oxygen cannula for 5 minutes, and 30 L/min oxygen in the same manner during and after the procedure. The incidence of desaturation was found to be significantly lower in GTK15 (7%) and GCK30 (2%) compared to GTK5 (31%) (p<0.05). Advanced desaturation was not detected in any patient in GTK15 and GTK30, while it was detected in 18% of the GTK5 group (p<0.05). Severe desaturation was detected in 11% of the GTK5 group, while there was no severe desaturation in the other groups (p<0.05). The duration of desaturation was longer in GTK5 than in the other groups. The time to reach 99% oxygen saturation was significantly shorter in the G15 and G30 groups compared to the G5 group (p < 0.05). This time was significantly shorter in GCK30 than in GTK15 (p<0.05). However, there was a burning sensation in the nose in 30% of the patients in double nasal cannula oxygen applications (p<0.05). It was found that oxygen administration with a double nasal cannula had similar effectiveness to single nasal cannula 15 L/min flows in preventing respiratory complications in sedation applications performed for gastrointestinal system endoscopies, and that respiratory complications were significantly reduced at both flow rates compared to 5 L flow rates. It was also found that a single cannula 15 L/min application was better in terms of patient comfort.
