  • 文章类型: Journal Article
    这项研究的目的是比较HugeMed®视频喉镜与直接Macintosh喉镜在经鼻气管插管中的性能。
    88名4-10岁儿童被随机分配到HugeMed®视频喉镜(HVL)或Macintosh直接喉镜(MDL)组。插管困难,声门视图等级,插管时间,尝试气管插管的次数,使用外部喉部操作和Magill镊子,恢复时间,小儿麻醉谵妄量表(PAEDS)评分,气管插管引起的疼痛,和喉部出血进行评估。
    HVL组易气管插管发生率高于MDL组(p=0.001)。与MDL组相比,HVL组的声门视图更好(p=0.027)。两组在气管插管时间方面没有差异,尝试气管插管的次数,马吉尔镊子的用法,疼痛,以及气管插管引起的出血.与HVL组相比,MDL组需要进行外部喉部操作(p=0.004)和PAEDS评分(p=0.006)。
    HugeMed®可视喉镜可以提供更容易的气管插管,创造一个更好的声门视图,与Macintosh直接喉镜相比,显着减少了对额外操作的需求,用于经鼻气管插管.
    www.clinicaltrial.gov标识符是NCT05121597。
    UNASSIGNED: The aim of this study was to compare the performance of the HugeMed® videolaryngoscope with a direct Macintosh laryngoscope for nasotracheal intubation.
    UNASSIGNED: Eighty-eight children aged 4-10 years were randomly assigned to either the HugeMed® videolaryngoscope (HVL) or the Macintosh direct laryngoscope (MDL) group. Intubation difficulty, glottic view grade, time-to-intubation, number of tracheal intubation attempts, use of external laryngeal manipulation and Magill forceps, recovery time, pediatric-anesthesia-delirium-scale (PAEDS) scores, pain due to tracheal intubation, and laryngeal bleeding were evaluated.
    UNASSIGNED: Easy tracheal intubation incidence was higher in the HVL group than that in the MDL group (p = 0.001). Glottic view was better in the HVL group as compared to the MDL group (p = 0.027). There was no difference between the groups in terms of time-to-tracheal intubation, number of tracheal intubation attempts, Magill forceps usage, pain, and bleeding due to tracheal intubation. The need for external laryngeal manipulation (p = 0.004) and PAEDS scores (p = 0.006) were higher in the MDL group than those in the HVL group.
    UNASSIGNED: HugeMed® videolaryngoscope may provide easier tracheal intubation, create a better glottic view, and significantly reduce the need for additional manipulation compared to the Macintosh direct laryngoscope, for nasotracheal intubation.
    UNASSIGNED: www.clinicaltrial.gov identifier is NCT05121597.

    咽喉功能不全是一种软腭通过鼻子引导空气的疾病。它通常存在于先前有left裂或短腭的患者中,但在许多其他条件下也是如此。症状主要是在言语中发现的,有非常明显的鼻音。经过临床评估和鼻内镜检查,考虑手术。几种手术技术正在使用中,咽后瓣咽部成形术应用最广泛。这种方法使咽后瓣的底部附着在咽后壁上,在襟翼的每一侧有两个侧向端口。在强制性鼻插管的情况下,永久性鼻咽阻塞对麻醉师来说是非常具有挑战性的病理,因为它是鼻插管的相对禁忌症。以前进行过pal的患者会定期出现在我们的常规麻醉实践中,在所有手术部分。如果不意识到该手术的永久效果,则可能出血的皮瓣损坏的高风险会使麻醉师处于非常不愉快的情况。在麻醉前评估期间,如果有关于以前咽部成形术的信息,应考虑鼻气管插管的替代方案.必须避免或谨慎进行所有鼻腔插入程序,在光纤视觉控制下。
    Velopharyngeal insufficiency is a disorder where the soft palate directs the air through the nose. It is often present in patients with previous cleft or short palate, but also in many other conditions. Symptoms are primarily to be found in speech, with very distinct nasal sound. After clinical evaluation and nasal endoscopy, surgery is considered. Several surgical techniques are in use, with posterior pharyngeal flap pharyngoplasty being most widely used. This method leaves the base of the posterior pharyngeal flap attached to the posterior pharyngeal wall, with two lateral ports on each side of the flap. Permanent nasopharyngeal obstruction is a very challenging pathology for anesthesiologists in case of mandatory nasal intubation since it is a relative contraindication for nasal intubation. Patients with previous palatoplasty will regularly appear in our routine anesthetic practice, in all surgical segments. The high risk of damage to the flap with possible bleeding can put the anesthesiologist in a very unpleasant situation if not aware of the permanent effect of this surgery. During preanesthetic assessment, if there is information on a previous pharyngoplasty, one should consider alternative options for nasotracheal intubation. All nasal insertion procedures must be either avoided or carried out with great caution, under fiberoptic visual control.

    一名45岁的男性患有舌癌和阻塞性睡眠呼吸暂停,接受舌癌切除术和右颈淋巴结清扫术。他在探条和滑眼镜的辅助下进行了艰难的鼻插管。在一个原本平静的程序之后,患者被拔管并恢复。几个小时后,他的呼吸增加,氧气(O2)饱和度降低,胸部右侧的空气运动减少。胸部X线检查证实右侧气胸。放置胸管,立即改善O2饱和度和呼吸。气胸可能是由于插管造成的创伤。尽管气胸是插管的潜在并发症,它更有可能在插管后不久而不是数小时后发生。机制往往是未知的。提供者必须在整个围手术期监测患者的任何潜在呼吸问题,尤其是在困难的插管之后。这将确保及时诊断和处理任何并发症,并为患者提供最佳结果。
    A 45-year-old male with tongue cancer and obstructive sleep apnea presented for glossectomy and right neck dissection. He underwent a difficult nasal intubation assisted by a bougie and Glidescope. After an otherwise uneventful procedure, the patient was extubated and taken to recovery. Several hours later, he developed increased respirations and decreased oxygen (O2) saturation with decreased air movement on the right side of his chest. A chest X-ray confirmed a right pneumothorax. A chest tube was placed with immediate improvement of O2 saturation and breathing. Pneumothorax was presumably due to trauma from intubation. Although pneumothorax is a potential complication of intubation, it is more likely to occur shortly following intubation instead of hours later. The mechanism is often unknown. Providers must monitor patients throughout the perioperative period for any potential respiratory concerns, especially following a difficult intubation. This will ensure prompt diagnosis and management of any complications and provide an optimal outcome for the patient.

    颞下颌关节强直病例对外科医生和麻醉师来说都是一个挑战,这可能是由于偏远地区资源不可用。由其强直引起的令人不安的问题包括功能和美学问题,例如在管理气道方面存在相当大的困难,特别是在儿童中,因为他们的气道的生理和结构不同。纤维支气管镜(FOB)在气道困难的患者中具有公认的作用,但这在儿科患者中尤其具有挑战性,因为他们缺乏合作和肺储备减少。用于保护成人气道的技术对于儿童来说可能并不理想,并且有时可能没有专用设备。在这里,我们介绍了一个14岁男孩的颞下颌关节(TMJ)强直的病例。这项研究旨在描述管理他的气道所经历的困难。
    Temporomandibular joint ankylosis cases serve as a challenge for both surgeons and anesthesiologists possibly due to the unavailability of resources in remote locations. Distressing issues brought on by its ankylosis include functional as well as esthetic issues such as considerable difficulties in managing the airway, especially in children because of the physiology and structure of their airways being different. Fiberoptic bronchoscopy (FOB) has a well-established role in patients with difficult airways, but it is especially challenging in pediatric patients because of their lack of cooperation and diminished lung reserve. Techniques used to secure airways in adults may not be ideal for children and sometimes dedicated equipment may not be available. Here we present a case of a 14-year-old boy with temporomandibular joint (TMJ) ankylosis. This study aimed to describe the difficulties experienced in managing his airway.

    经鼻气管插管(TI)在儿科重症监护病房(PICU)中占所有TI的一小部分。鼻TI的风险和益处没有得到很好的量化。因此,关于这种做法的安全性和描述性数据是必要的。
    我们在2013年至2020年前瞻性收集的质量改进数据库(国家儿童紧急航线登记处:NEAR4KIDS)中评估了TI航线与安全结果之间的关联。主要结局为重度去饱和(SpO2比基线>20%)和/或严重不良TI相关事件(TIAEs),使用NEAR4KIDS定义。为了平衡病人,提供者,和实践协变量,我们利用倾向评分(PS)匹配来比较鼻部与鼻部的结果。口服TI。
    总共22,741次[鼻部870(3.8%),从60个PICU中报告了口服21,871(96.2%)]。婴儿在鼻TI中的比例高于口服TI(75.9%,vs46.2%),以及患有心脏病的儿童(46.9%vs.14.4%),两者p<0.001。严重的去饱和或严重的TIAE发生在23.7%的鼻腔和22.5%的口服TI中(未调整的p=0.408)。使用PS匹配,严重去饱和和/或严重不良TIAEs的患病率为鼻vs.口服TI的19.8%(绝对差3.8%,95%置信区间(CI):-0.07,7.7%),p=0.055。首次尝试成功率为鼻TI的72.1%,口服TI的69.2%,p=0.072。使用PS匹配,两组的成功率没有差异(鼻部72.2%vs.口服71.5%,p=0.759)。
    在这项大型国际前瞻性队列研究中,严重的围插管并发症的风险并没有显著升高.鼻TI在PICU的少数TI中使用,病人有很大的差异,提供者,与口服TI相比,实践。可能需要进行前瞻性多中心试验以解决潜在的选择偏差并确认鼻TI的安全性。
    UNASSIGNED: Nasal tracheal intubation (TI) represents a minority of all TI in the pediatric intensive care unit (PICU). The risks and benefits of nasal TI are not well quantified. As such, safety and descriptive data regarding this practice are warranted.
    UNASSIGNED: We evaluated the association between TI route and safety outcomes in a prospectively collected quality improvement database (National Emergency Airway Registry for Children: NEAR4KIDS) from 2013 to 2020. The primary outcome was severe desaturation (SpO2 > 20% from baseline) and/or severe adverse TI-associated events (TIAEs), using NEAR4KIDS definitions. To balance patient, provider, and practice covariates, we utilized propensity score (PS) matching to compare the outcomes of nasal vs. oral TI.
    UNASSIGNED: A total of 22,741 TIs [nasal 870 (3.8%), oral 21,871 (96.2%)] were reported from 60 PICUs. Infants were represented in higher proportion in the nasal TI than the oral TI (75.9%, vs 46.2%), as well as children with cardiac conditions (46.9% vs. 14.4%), both p < 0.001. Severe desaturation or severe TIAE occurred in 23.7% of nasal and 22.5% of oral TI (non-adjusted p = 0.408). With PS matching, the prevalence of severe desaturation and or severe adverse TIAEs was 23.6% of nasal vs. 19.8% of oral TI (absolute difference 3.8%, 95% confidence interval (CI): - 0.07, 7.7%), p = 0.055. First attempt success rate was 72.1% of nasal TI versus 69.2% of oral TI, p = 0.072. With PS matching, the success rate was not different between two groups (nasal 72.2% vs. oral 71.5%, p = 0.759).
    UNASSIGNED: In this large international prospective cohort study, the risk of severe peri-intubation complications was not significantly higher. Nasal TI is used in a minority of TI in PICUs, with substantial differences in patient, provider, and practice compared to oral TI.A prospective multicenter trial may be warranted to address the potential selection bias and to confirm the safety of nasal TI.

    目的:颈动脉内膜切除术后血肿是一种毁灭性的并发症,在未控制的高血压和麻醉后咳嗽的患者中更有可能发生。我们试图确定使用鼻气管导管(ETT)而不是口服ETT插管是否与“更光滑”(即,较少的血流动力学不稳定性)从颈动脉内膜切除术的全身麻醉中出现。
    方法:纳入2015年12月至2021年9月在一个三级学术医疗中心接受颈动脉内膜切除术的患者。我们检查了323名在6年研究期间接受颈动脉内膜切除术的患者的电子麻醉记录,并记录了拔管前10分钟内的连续收缩压值,以替代出现的“平滑度”。
    结果:经鼻ETT插管,与口服ETT插管相比,与最大值的任何差异无关,minimum,平均,中位数,或拔管前十分钟内连续收缩压值的标准偏差。口服ETT患者出现时的平均收缩压为141mmHg,鼻ETT患者出现时的平均收缩压为144mmHg(P=0.562)。口腔和鼻腔ETT患者的最大收缩压分别为170mmHg和174mmHg,分别为(P=0.491)。出现的定性“平滑度”或需要静脉注射一种或多种抗高血压药物的患者百分比也没有差异。两组术后并发症发生率相似。
    结论:当收缩压作为颈动脉内膜切除术全身麻醉出现的平滑性的替代指标时,与口服ETT插管相比,经鼻ETT插管与更好的血流动力学稳定性无关.
    BACKGROUND: Postoperative hematoma after carotid endarterectomy (CEA) is a devastating complication and may be more likely in patients with uncontrolled hypertension and coughing on emergence from anesthesia. We sought to determine if intubation with a nasal endotracheal tube (ETT)-instead of an oral ETT-is associated with \"smoother\" (i.e., less hemodynamic instability) emergence from general anesthesia for CEA.
    METHODS: Patients receiving CEA between December 2015 and September 2021 at a single tertiary academic medical center were included. We examined the electronic anesthesia records for 323 patients who underwent CEA during the 6-year study period and recorded consecutive systolic blood pressure (SBP) values during the 10 minutes before extubation as a surrogate for \"smoothness\" of the emergence.
    RESULTS: Intubation with a nasal ETT, when compared with intubation with an oral ETT, was not associated with any difference in maximum, minimum, average, median, or standard deviation of serial SBP values in the 10 minutes before extubation. The average SBP on emergence for patients with an oral ETT was 141 mm Hg and with a nasal ETT was 144 mm Hg (P = 0.562). The maximum SBP for patients with oral and nasal ETTs were 170 mm Hg and 174 mm Hg, respectively (P = 0.491). There were also no differences in the qualitative \"smoothness\" of emergence or in the percentage of patients who required an intravenous dose of 1 or more antihypertensive medications. The incidence of postoperative complications was similar between the 2 groups.
    CONCLUSIONS: When SBP is used as a surrogate for smoothness of emergence from general anesthesia for CEA, intubation with a nasal ETT was not associated with better hemodynamic stability compared to intubation with an oral ETT.

    背景:鼻气管插管(NI)的程序长期以来是利用由IvanMagill爵士在1920年代开发的Magill镊子进行的。虽然使用了近一个世纪,一些严重的患者安全问题仍然存在,包括撕裂的套管袖口,声带创伤,和低效的管放置。Tylke镊子已被开发为对Magill镊子的基本不变形式的改进。
    方法:在本研究中,我们比较了疗效,扣钩的数量,在以前未经训练的个体中,使用Tylke镊子与Magill镊子进行NI相关的肌肉激活。
    结果:Tylke镊子在平均插管时间为6.54s与标准Magill镊子相比显示出更快的NI成功率13.73s,分别。每次在Magill上插管时,Tylke镊子的扣钩也较少。斜方肌,三角肌,在Tylke和Magill镊子插管试验中,还比较了肱肌激活。与使用Tylke镊子的Magill镊子相比,Tylke镊子在肱和斜方肌中需要更少的肌肉激活,从而导致更高的三角肌激活。
    结论:在不同肌肉激活模式的成功NI中使用时,Tylke钳更有效,并且减少了Magill钳的扣钩数量。
    BACKGROUND: The procedure of nasotracheal intubation (NI) has long been performed utilizing the Magill forceps as developed by Sir Ivan Magill in the 1920s. While used for nearly a century, several serious patient safety concerns remain including torn tube cuffs, vocal cord trauma, and inefficient tube placement. The Tylke forceps have been developed as a modification to the largely unchanged form of Magill forceps.
    METHODS: In the present investigation we compared the efficacy, number of clasps, and muscle activation involved in NI using the Tylke forceps versus the Magill forceps in previously untrained individuals.
    RESULTS: Tylke forceps showed faster successful NI over the standard Magill forceps at an average intubation time of 6.54s vs. 13.73s, respectively. Tylke forceps also had fewer clasps per intubation over the Magill. The trapezius, deltoid, and brachioradialis muscle activation was also compared in Tylke vs Magill forceps intubation trials. Tylke forceps required less lower muscle activation in the brachioradialis and trapezius over the Magill forceps with Tylke forceps resulting in higher deltoid muscle activation.
    CONCLUSIONS: Tylke forceps were more efficacious and reduced the number of clasps over the Magill forceps when used in successful NI with different muscle activation patterns.

    免疫球蛋白A(IgA)缺乏症是最常见的免疫疾病之一,其特征是对感染的易感性增加。特别是涉及口腔的呼吸道和粘膜表面,牙龈,还有鼻窦.因为牙科手术和全身麻醉可能会增加全身感染的风险,在牙科手术和插管全身麻醉期间,IgA缺乏患者的管理需要谨慎。我们报告了一名5岁的IgA缺乏症女性患者,她在全身麻醉下拔除了18颗乳牙。围手术期使用抗生素预防和抗菌漱口水以降低菌血症风险。在将局部消毒剂和含肾上腺素的纱布包装入鼻腔后,小心地进行鼻气管插管,以最大程度地减少创伤。在医院中对患者进行了整夜的仔细监测,并在第二天出院,没有任何感染迹象或症状。牙科麻醉提供者必须意识到在管理IgA缺乏症患者时对安全实践的潜在影响。
    Immunoglobulin A (IgA) deficiency is one of the most common immune disorders characterized by increased susceptibility to infections, especially involving the respiratory tract and mucosal surfaces of the mouth, gingiva, and nasal sinus. Because dental surgery and general anesthesia may pose an increased risk for systemic infections, management of IgA-deficient patients requires caution during dental procedures and intubated general anesthesia. We report a 5-year-old female patient with IgA deficiency who underwent extraction of 18 deciduous teeth under general anesthesia. Antibiotic prophylaxis and antiseptic mouthwash were used perioperatively to reduce bacteremia risks. Nasotracheal intubation was carefully performed after applying topical disinfectants and epinephrine-containing gauze packing into the nasal cavity to minimize trauma. The patient was carefully monitored overnight in the hospital and discharged without any signs or symptoms of infection the next day. Dental anesthesia providers must be aware of the potential implications for safe practice when managing patients with IgA deficiency.

    Ameloblastomas are rare tumors that arises from the odontogenic epithelium. Although benign and slow growing, an extensive lesion may cause airway obstruction, making bag-mask ventilation and intubation a significant challenge. Here, we present a 54-year-old male in respiratory distress with an 18x15x13 cm submandibular mass causing airway compromise. The tumor was extensive, occupying most of the oral cavity. Unable to perform direct laryngoscopy because of the tumor burden, we performed an awake nasal fiberoptic intubation to secure the airway. Successful intubation was achieved as well as subsequently tracheostomy. We subsequently provide a discussion on associated challenges and management options for patients with ameloblastomas.
