Figures & data
Figure 1 Frontal (a) and lateral (b) views of a mouth maximally opened due to the use of a mouth prop; an individual plastic plate (c). An individual plastic plate (an oral appliance) was created to measure the OC in the MMAT and MMSP. In addition, Frontal (a) and lateral (b) views showed the maximum opening position with a mouth prop at Term 1 and Term 2.
Figure 2 Changes in the mBP, PR, and SpO2. SpO2 significantly decreased 10, 15, 20, and 25 min after PPF administration (from an average of 95 to 100%) (P < 0.01). Furthermore, mBP significantly decreased 10, 15, 20, and 25 min after PPF administration (from an average of 68 to 112 mmHg) (P < 0.01). No significant difference was observed in PR 10, 15, 20, and 25 min after the start of PPF infusion (from an average of 70 to 73 bpm).
Figure 3 Changes in the RASS. RASS significantly decreased 10, 15, 20, and 25 min after PPF administration compared with the baseline value. No significant differences were observed in the RASS between 14 min after the start of PPF infusion and Term 1 as well as between 19 min after the start of PPF infusion and Term 2. However, a significant difference was observed in the RASS between Terms 1 and 2 (P < 0.05).
Figure 4 Changes in the OC in the MMAT and MMSP. The OC in the MMAT at Term 2 significantly increased compared with the baseline value (P < 0.01). Furthermore, compared with the baseline value in the MMSP, the OC at 14 and 19 min after the start of PPF infusion and at Term1 and Term2 significantly increased (P < 0.05; OC at 14 min, Term1, and 19 min, P < 0.01; OC at Term2;).
Figure 5 Comparison of the OC before and after the use of a mouth prop. Comparison of the OC before and after the use of a mouth prop revealed no significant differences in the MMAT and MMSP. However, the OC in the MMAT and MMSP at Term 2 exhibited an increasing trend although the difference was not statistically significant.
