SJOV in hysteroscopic surgery

This study investigates whether Supraglottic Jet Oxygenation and Ventilation (SJOV) can prevent hypoxemia during hysteroscopic surgery，and this single-center, randomized controlled trial demonstrates that the proactive application of SJOV using the Wei nasal jet tube is significantly more effective than standard nasal cannula oxygenation in maintaining oxygenation during hysteroscopic surgery under sedation. In the table, N represents the use of nasal cannula oxygen therapy, and S represents the use of SJOV (Surgical Jaw Opening Ventilation) therapy. In the sheet “N Group”, cell BG34 indicates that the patient in row 34 experienced intraoperative hypoxemia (75% ≤ SpO? < 90%) 3 times. Cell BF34 refers to the lowest SpO? value among these three hypoxemic episodes. Cell BH34 refers to the duration (in seconds) of each of these three hypoxemic episodes. Other cells follow the same logic.

本研究旨在探讨声门上喷射供氧通气（Supraglottic Jet Oxygenation and Ventilation，SJOV）是否可预防宫腔镜手术期间的低氧血症。这项单中心随机对照试验证实，采用韦氏鼻腔喷射导管主动实施SJOV，在镇静状态下的宫腔镜手术中，其维持氧合的效果显著优于标准鼻导管吸氧。本表格中，N代表采用鼻导管氧疗，S代表采用SJOV（经口开放气道通气，Surgical Jaw Opening Ventilation）治疗。在"N组"工作表内，单元格BG34表示第34行的患者术中出现3次低氧血症（75%≤脉搏血氧饱和度<90%）；单元格BF34指代该3次低氧发作中的最低脉搏血氧饱和度值；单元格BH34指代该3次低氧发作各自的持续时长（单位：秒）。其余单元格均遵循相同逻辑。
