Abstract: PURPOSE: This clinical trial was performed to evaluate the effect of nasal tube stabilization (NTS) on pressure between tube and nose(PTN) in both supine and neck extension position. METHODS: Twenty-four ASAⅠorⅡ adult patients scheduled for oral and maxillofacial surgeries requiring naso tracheal intubation(NTI) were randomly assigned to intubate with either wire-reinforced or Ring-Adair-Elwyn tube. Thin film pressure sensor was used to measure PTN before and after NTS in both supine and neck extension position. Statistical analysis was performed with Graphpad Prism 9.0 software package. RESULTS: The PTN of wire-reinforced tubes were 51 mmHg higher than that of RAE tubes in supine position before NTS (P=0.005), and 68 mmHg higher than that in extension position before NTS (P=0.0007). In wire-reinforced tube group before NTS, the PTN of neck extension position increased by 24 mmHg compared with supine position (P=0.0005). After NTS, the PTN in supine and neck extension position was comparable (P=0.1514). NTS significantly reduced PTN in both supine (P=0.0005) and neck extension position (P=0.0005); while in RAE tube group before NTS, the PTN in supine and neck extension position was comparable (P=0.3394). After NTS, the pressure in supine and neck extension position was comparable(P=0.7910). NTS also significantly reduced PTN in both supine (P=0.0005) and neck extension position (P=0.0005). CONCLUSIONS: NTS effectively reduced PTN of both wire-reinforced and RAE tubes regardless of supine or neck extension position. RAE tube also significantly reduced PTN compared with wire-reinforced tube.
