Clinical Application of Shikani Optical Stylet in Guiding Nasal Tracheal Intubation / 中国微创外科杂志

Objective To explore the clinical application of the Shikani optical style(SOS)in guiding nasal tracheal intubation.Methods A retrospective analysis was made on clinical data of 60 patients who underwent selective operation under general anesthesia through nasal tracheal intubation from January 2017 to December 2022.According to the guidance methods of nasal tracheal intubation,the patients were divided into three groups with 20 cases in each group:video laryngoscope guided nasal tracheal intubation group(group V),fiberoptic bronchoscopy guided nasal tracheal intubation group(group F),and SOS guided nasal tracheal intubation group(group S).The grading of glottis exposure and epistaxis during tracheal intubation were recorded,as well as the success rate,completion time,and incidence of postoperative complications related to nasal tracheal intubation.Results The glottis exposure in the group F and group S were both grade Ⅰ.Among the group V,there were 7 cases of gradeⅠ,10 cases of gradeⅡ,and 3 cases of grade Ⅲ.The glottis exposure effect of patients in the group F and S was significantly better than that of the group V(Z =-4.274,P = 0.000;Z =-4.274,P = 0.000).There were 15 and 14 patients in the group F and the group S without epistaxis,and 5 and 6 patients with mild epistaxis,respectively.There were no patients with severe epistaxis in the group F and the group S.In the group V,there were 7 patients without epistaxis,10 patients with mild epistaxis,and 3 patients with severe epistaxis.The degree of epistaxis in the group F and the group S was significantly less than that in the group V(Z =-2.678,P =0.007;Z =-2.402,P =0.016).The median time for tracheal intubation in the group S was 37.5(34.3,41.5)s,significantly shorter than 45.0(39.8,72.5)s in the group V and 89.0(76.0,102.5)s in the group F(Z =15.703,P =0.013;Z =32.050,P =0.000),with the group V being significantly shorter than the group F(Z =-16.347,P =0.009).The nasal tracheal intubation failed in 2 cases in the group V,while was all successfully completed in the group F and the group S.The difference of success rate was not statistically significant among the three groups(P>0.05).There were no statistically significant differences in the rates of postoperative nasopharyngeal pain and nasal congestion among the three groups(P>0.05).Conclusion The method of SOS-guided nasal tracheal intubation can provide good glottis exposure and achieve a satisfactory success rate of tracheal intubation without increasing the risk of adverse reactions,which can be regarded as a safe and effective method of nasal tracheal intubation.

Anesthesia for a patient with base of tongue mass undergoing transoral robotic surgery: A case report

@#Transoral robotic surgery (TORS) is a minimally invasive surgical technique that has recently gained popularity. This involves the use of a robotic system to access and operate on hard-to-reach areas of the body, such as the base of tongue and pharynx. General anesthesia is the technique of choice in TORS as this procedure poses unique challenges due to the patient's airway anatomy, the need for precise surgical movements, and the potential for postoperative complications. Awake fiberoptic intubation (AFOI) is the gold standard for an anticipated difficult airway. This case report describes the anesthetic management for a patient undergoing TORS for a tongue base mass.

COMPARISON OF CT VIRTUAL BRONCHOSCOPY WITH FIBRE OPTIC BRONCHOSCOPY IN THE EVALUATION OF ENDO-BRONCHIAL LESIONS

Background: Virtual bronchoscopy is a noninvasive tool for assessing the airway. It can be used along with multiplanar CT scan for better assessment of endobronchial tree. A lot of researches has been conducted in various parts of the world weather CT bronchoscopy can replace actual flexible fiberoptic bronchoscopy. We aimed to explore the utility of virtual bronchoscopy (VB) for evaluation of tracheobronchial lesions and weather this can be helpful for pulmonologist for better assessment of airway while using real time flexible bronchoscopy. Our age group comprised of patients from 21 years to a maximum a Results : ge of 80 years with a mean age of 52.6 years. VB was better in detecting external compression with a Kappa value of 0.68. VB had a moderate agreement with FOB to detect endoluminal lesions with kappa value of 0.70. None of the mucosal changes detected by FOB was detected by VB. In detecting obstructive lesions VB substantially agreed with FOB with a kappa value of 0.8. Moderate agreement was seen by VB in detecting both malignant and non-malignant lesions vompared to FOB. Virtual bronchoscopy when used in conjunction with axial CT Conclusion: images can enhance diagnostic accuracy of bronchial pathologies. VB cannot replace conventional bronchoscopy due to associated disadvantages such as the inability to perform a biopsy, the inability to detect mucosal infiltration, the relatively low specificity rate when compared to high sensitivity rates, and the inability to offer real-time evaluation

Application of fiberoptic endoscopic examination of swallowing combined with dye test in silent aspiration after stroke / 中国康复理论与实践

ObjectiveTo explore the diagnostic value of fiberoptic endoscopic examination of swallowing (FEES) combined with dye test in patients with post-stroke dysphagia and silent aspiration. MethodsFrom December, 2021 to June, 2022, 50 stroke patients in the Rehabilitation Department of Xuzhou Central Hospital were selected. They were assessed with FEES and videofluoroscopic swallowing study (VFSS), and compared. ResultsThe detection rate of aspiration was higher with FEES than with VFSS (χ2 = 7.000, P < 0.05), and especially for liquid food (χ2 = 4.000, P < 0.05). There was a good consistency when consuming paste food (κ = 0.941, P < 0.001) and solid food (κ = 0.779, P < 0.001). There was a good consistency in the food residue site between two methods (κ = 0.818, P < 0.001), as well as for all the three food types (κ ≥ 0.862, P < 0.001). There was no significant difference in the scores of Penetration Aspiration Scale of three food types between two methods (Z < 0.667, P > 0.05). ConclusionFEES combined with dye test can be used for evaluating silent aspiration after stroke.

Carcinoma pulmonar de celulas pequeñas en paciente neumonectomizada no fumadora - primera criobiopsia por fibrobroncoscopia en bolivia, presentación de caso clínico / Small cell lung carcinoma in a non-smoking pneumonectomized patient - first cryobiopsy by fibrobronchoscopy in Bolivia, case report

El cáncer broncogénico tiene una base genética, que se expresa por factores externos relacionados a la exposición medioambiental y laboral, en los últimos años ha cambiado el perfil epidemiológico con incidencia creciente en mujeres sin hábito tabáquico en rangos de 50-70 años. Paciente femenino de 50 años con el antecedente de exposición a humo de leña y uso de pesticidas, con síndrome de atelectasia pulmonar masiva izquierda. Se realizó estudios fibrobroncoscopicos con toma de biopsia de masa tumoral endobronquial izquierda y se realizó la primera criobiopsia por fibrobroncoscopía en Bolivia, posteriormente paciente fue sometida a neumonectomia izquierda con estudio histopatológico concluyente de carcinoma indiferenciado de células pequeñas con primario pulmonar.

Fibrobronchoscopy studies were performed with a biopsy of the left endobronchial tumor mass and the first cryobiopsy was performed by fibrobronchoscopy in Bolivia, later the patient underwent left pneumonectomy with a conclusive histopathological study of undifferentiated small cell carcinoma with a pulmonary primary. There is a strong association between environmental and occupational exposure and bronchogenic cancer in non-smokers, even in infrequent histopathological variants in this subgroup such as small cell or microcytic cancer.

Endobronchial Ultrasound Bronchoscopy in Patients with Acute Respiratory Failure on Noninvasive Ventilation: Report of Two Cases

Fiberoptic bronchoscopy (FOB) has simplified the direct examination of the lungs and is widely used for diagnosis and therapy. Fiberoptic bronchoscopes occupy a significant proportion of cross-section area of central airways, which can affect lung mechanics and gas exchanges that may lead to desaturation and cardiac arrhythmia. This makes bronchoscopy in critically ill patients with respiratory failure even more challenging. Use of noninvasive mechanical ventilation (NIV) may help to avoid use of invasive mechanical ventilation in selected patients with acute respiratory failure. It has been shown to be useful in hypoxemic patients to facilitate bronchoscopic examination for bronchoalveolar lavage, bronchial brushing, endobronchial biopsy (EBB), and transbronchial lung biopsy (TBLB). Noninvasive mechanical ventilation has also been used to facilitate other endoscopic procedures including transesophageal echocardiography (TEE) and upper gastrointestinal endoscopy for diagnostic and therapeutic interventions in hypoxemic patients. Endobronchial ultrasound (EBUS) bronchoscope, having a wider diameter than a conventional bronchoscope, may have a more pronounced effect on lung mechanics and gas exchanges, and its use in patients on NIV has not been reported. Contraindications of EBUS are mostly relative and similar to FOB. There are several studies suggesting the safety of NIV-supported FOB in hypoxemic patients. We describe our experience of the first two EBUS bronchoscopies and transbronchial needle aspiration (TBNA) was done in hypoxemic patients with NIV support.

Fiberoptic endoscopic evaluation of swallowing and the Brazilian version of the Eating Assessment Tool-10 in resistant hypertensive patients with obstructive sleep apnea

Abstract Objective: The aim of this study was to describe the prevalence and characteristics of OD through Fiberoptic Endoscopic Evaluation of Swallowing (FEES) and the Eating Assessment Tool-10 (EAT-10) in hypertensive patients with OSA, as well as to describe the sensitivity of EAT-10 for the detection of OD in this population. Methods: This study included a convenience sample in which 85 resistant hypertensive patients diagnosed with OSA in an university hospital participated. Participants were subjected to the EAT-10 (index test) and FEES (reference standard). Results: The median EAT-10 score was 2 (0-5.5). According to the FEES, 27 participants did not have dysphagia, 42 had mild dysphagia and 16 had mild to moderate dysphagia. The sensitivity of the EAT-10 was 70.7% (95% CI: 57.3-81.9) at a cutoff score ≤1, with a discriminatory power of 67.4% (p = 0.005). The most prevalent symptom in this population was "food stuck in the throat", while the most prevalent signs were delayed initiation of the pharyngeal phase of swallowing, premature bolus spillage and pharyngeal residue. Conclusion: In our study, the cutoff score for the EAT-10 for screening for OD in this population was ≥ 1. In conclusion, this population presented a high prevalence of dysphagia detected in FEES and its severity is associated with higher EAT-10 scores.

Intubation with Vivasight Double?Lumen Tube Versus Conventional Double?Lumen Tube in Adult Patients Undergoing Lung Resection: A Retrospective Analysis

Objectives: The present study was designed to compare outcomes in patients undergoing thoracic surgery using the VivaSight double?lumen tube (VDLT) or the conventional double?lumen tube (cDLT). Design: A retrospective analysis of 100 patients scheduled for lung resection recruited over 21 consecutivemonths (January 2018–September 2019). Setting: Single?center university teaching hospital investigation. Participants: A randomized sample of 100 patients who underwent lung resection during this period were selected for the purpose to compare 50 patients in the VDLT group and 50 in the cDLT group. Interventions: After institutional review board approval, patients were chosen according to inclusion and exclusion criteria and we created a general database.The 100 patients have been chosen through a random process with the Microsoft Excel program (Microsoft 2018, Version 16.16.16). Measurements and Main Results: The primary endpoint of the study was to analyze the need to use fiberoptic bronchoscopy to confirm the correct positioning of VDLT or the cDLT used for lung isolation. Secondary endpoints were respiratory parameters, admission to the intensive care unit, length of hospitalization, postoperative complications, readmission, and 30?day mortality rate. The use of fiberoptic bronchoscopy was lower in the VDLT group, and the size of the tube was smaller.The intraoperative respiratory and hemodynamics parameters were optimal. There were no other preoperative, intraoperative, or postoperative differences between both groups. Conclusions: TheVDLT reduces the need for fiberoptic bronchoscopy, and it seems that a smaller size is needed.Finally,VDLT is cost?effective using disposable fiberscopes.

Disnea secundaria a oclusión subaguda de un bronquio fuente / Dyspnea secondary to subacute occlusion of a main bronchus

La presencia de un cuerpo extraño en la vía aérea es todo un desafío diagnóstico, especialmente cuando el paciente no manifiesta una etapa asfíctica y el cuadro clínico se presenta silente o lentamente progresivo. Pero también es un desafío terapéutico, dado que no es frecuente disponer de broncoscopía rígida y flexible en la misma institución médica ni tampoco suele haber una variedad de instrumental para poder asirlo, en especial cuando el objeto es romo y voluminoso, con lo cual la extracción del mismo requiere no sólo de pericia, sino de paciencia e inventiva para poder resolver el problema con los escasos medios que habitualmente se cuentan.

The presence of a foreign body in the airways is a diagnostic challenge, especially when the patient doesn't show an asphyctic stage and is in a silent or slowly progressive clinical condition. But it is also a therapeutic challenge, given the fact that it is not common to have both rigid and flexible bronchoscopies in the same medical institution, or a variety of tools to grab the foreign body, mostly when the object is blunt and voluminous, so that in order to be extracted the physician must have skill, patience and imagination to solve the problem with the few resources usually available.

Clinical characteristics and risk factors for plastic bronchitis caused by severe mycoplasma pneumonia in children / 中国小儿急救医学

Objective:To summarize the clinical characteristics of plastic bronchitis caused by severe mycoplasma pneumoniae pneumonia in children, to find the risk factors for plastic bronchitis, and to provide references for judging the prognosis and comprehensively formulating treatment plans.Methods:We retrospectively analyzed the clinical data(146 cases)of children with severe mycoplasma pneumoniae pneumonia who underwent bronchoscopy in the Department of Pediatric Respiratory Medicine of Shengjing Hospital of China Medical University from January 2017 to December 2019.According to whether it was plastic bronchitis, all patients were divided into plastic bronchitis group(68 cases) and non-plastic bronchitis group(78 cases), and the gender, age, laboratory examination indicators, imaging characteristics and treatment of children were collected under the circumstances.The single factor with clinical significance and statistical significance would be subjected to multivariate Logistic regression analysis.Results:There were no significant differences in gender, age, heat duration, white blood cell count, C-reactive protein value, and interleukin-6 value between the two groups(all P>0.05). The percentage of neutrophils, alanine aminotransferase, aspartate aminotransferase, lactate dehydrogenase, D-dimer, number of cases of pleural effusion, length of hospital stay, and number of endoscopy in the plastic bronchitis group were higher than those in non-plastic bronchitis group, the number of right upper lobe consolidation cases was less than that in the non-plastic bronchitis group, and the differences were statistically significant( P<0.05). Multiple Logistic regression analysis showed that pleural effusion( OR=4.898, 95% CI 2.195-10.926) and lactate dehydrogenase ( OR=1.051, 95% CI 1.003-1.101) were independent predictors of plastic bronchitis in children with severe mycoplasma pneumoniae pneumonia. Conclusion:For children with severe mycoplasma pneumoniae pneumonia, if lung CT shows that the upper lobe of the non-right lung is uniformly compacted and complicated with pleural effusion, lactate dehydrogenase is significantly increased, and attention should be paid to the possibility of plastic bronchitis.Timely improvement of fiberoptic bronchoscopy may shorten the course of the disease and reduce the occurrence of complications.

Role of flexible fiberoptic bronchoscopy in diagnosis of indefinate pulmonary infiltrates

Background: Respiratory diseases commonly present and are mostly diagnosed by routine clinical assessment and noninvasive investigations. Bronchoscopy a novel diagnostic tool used in diagnosis of various infectious, inflammatory and neoplastic pulmonary diseases by retrieving samples from bronchial, alveolar and interstitial compartments of patients with lung infiltrates. We prospectively assessed diagnostic utility of bronchoscopy in patients who had respiratory symptoms, radiographic infiltrates and sputum smear is negative for acid-fast bacilli (AFB). Despite, recent technical innovations in bronchoscopy, routine FOB is practiced with high yield and cost effectiveness.Methods: A prospective study was performed in which bronchoscopy was performed in 40 patients between August 2018 and January 2019, who had respiratory symptoms, radiographic findings not consistent with any specific diagnostic entity and had sputum smear negative for AFB.Results: Out of total 40 patients, most 30 (75%) patients were from rural areas, more than half 24 (60%) of the patients were males. Out of total 21 (52%) of patients were current smokers. Most common presenting symptoms were cough 22 (55%) and hemoptysis 8 (20%) followed by fever 6 (15%) and weight loss 4 (10%). Tuberculosis was confirmed in 18 (45%) patients. Non tubercular diseases were diagnosed in 22 (55%). Interstitial lung disease (ILD) was diagnosed in 5 (12.5%), lung cancer in 5%, bronhiectasis in 7.5%, pneumonia in 12.5%, lung abscess in 2.5% and non-specific infection in 15%.Conclusions: Diagnostic utility of flexible bronchoscopy is ever growing and has certainly taken a turn from being a luxury to near necessity today. Its association with trivial complications makes it a safe procedure. Hence bronchoscopy should be considered in the evaluation of patients with respiratory symptoms, indefinate radiographic infiltrates and negative sputum AFB test.

Airway Management In Extensive Facial Burns- A Case Report

Anesthetic management of burns of the head, neck, face and upper airway needs special precautions as establishing the airway provides challenges to the anesthesiologist. A 27 year old female presented with acute second degree thermal burns of the head, neck, face, shoulders and was posted for emergency escharotomy and dressing. Her scalp hair was singed, nasal mucosa was burnt and her whole face and neck were burnt with huge blisters and raw areas over the chest, shoulders and both upper limbs. Intravenous line was established through the right femoral vein and she was resuscitated with ringer lactate. Holding the face mask was impossible in view of her facial burns. Awake oro tracheal intubation was done by fiber optic onchoscopy guidance and airway was established successfully. Anesthesia was maintained by titrated doses of opioids, non-depolarising muscle relaxants and inhalational agents. She recovered well and was extubated awake. Hence awake fiber optic onchoscope guided intubation can be done to establish the airway in extensive head, neck, face and upper airway burns.
