AI Article Synopsis
- The study aimed to investigate if drug-induced sleep apnea (DISE) impacts surgical success in patients with obstructive sleep apnea (OSA).
- The trial included 326 patients from seven countries, comparing outcomes between a group that underwent DISE and one that did not.
- Results showed that patients in the DISE group had significantly worse outcomes, with a lower success rate (66.5% vs. 80.8%) and less improvement in blood pressure compared to those who did not undergo DISE.
Article Abstract
Objectives/hypothesis: Our objective was to determine whether drug-induced sleep apnea (DISE) affects the successfulness of the surgical outcome.
Study Design: Prospective, seven-country, nonrandomized trial.
Methods: There were 326 consecutive obstructive sleep apnea (OSA) patients who had nose, palate, and/or tongue surgery included in the study. DISE was performed in only one group.
Results: There were 170 patients in the DISE group and 156 patients in no-DISE group. The mean preoperative body mass index (BMI) for the DISE group was 27.6 ± 4.6, whereas in the no-DISE group it was 28.1 ± 3.9 (P = .23). The mean preoperative systolic blood pressure (SBP) for the DISE group was 130.4 ± 16.7, whereas in the no-DISE group it was 142.9 ± 15.5 (P < .001). The mean preoperative diastolic blood pressure (DBP) for the DISE group was 81.4 ± 9.7, whereas in the no-DISE group it was 89.1 ± 9.7 (P < .001). The mean preoperative apnea-hypopnea index (AHI) for the DISE group was 32.6 ± 18.8, whereas in the no-DISE group it was 33.7 ± 19.6 (P = .61). The mean postoperative AHI for the DISE group was 15.9 ± 12.6, whereas in the no-DISE group it was 13.2 ± 8.8 (P = .023). The age-, gender-, BMI-adjusted percentage change in AHI for the DISE group was -48.4 ± 31.9, whereas in the no-DISE group it was -59.8 ± 18.6 (P < .001). The age-, gender-, and BMI-adjusted success rate for the DISE group was 66.5%, whereas in the no-DISE group it was 80.8% (P = .004). The age-, gender-, and BMI-adjusted change in SBP for the DISE group was -6.1 ± 8.6, whereas in the no-DISE group it was -13.3 ± 11.1 (P < .001). The age-, gender-, and BMI-adjusted change in DBP in the DISE group was -5.2 ± 12.1, whereas in the no-DISE group it was -12.4 ± 11.7 (P < .001). The mean age- and gender-adjusted change in BMI for the DISE group was -4.6 ± 12.9, whereas in the no-DISE group it was -6.3 ± 18.5 (P = .34). The Cohen effect of BMI on the overall AHI, lowest oxygen saturation, and blood pressure changes was 0.08.
Conclusions: DISE may not significantly affect surgical success in OSA.
