Opioid-free general anesthesia and induced recovery from anesthesia in a patient with myotonic dystrophy type-1: a case report / Anestesia geral sem opioide e recuperação induzida da anestesia em paciente com distrofia miotônica tipo-1: relato de caso

Abstract Myotonic dystrophy type-1 (Steinert disease) is an autosomal dominant, progressive multisystem disease in which myotonic crisis can be triggered by several factors including pain, emotional stress, hypothermia, shivering, and mechanical or electrical stimulation. In this report, dexmedetomidine-based general anesthesia, in combination with a thoracic epidural for laparoscopic cholecystectomy in a patient with Steinert disease, is presented. An Aintree intubation catheter with the guidance of a fiberoptic bronchoscope was used for intubation to avoid laryngoscopy. Prolonged anesthetic effects of propofol were reversed, and recovery from anesthesia was accelerated using an intravenous infusion of theophylline.

Resumo A Distrofia Miotônica (DM) tipo-1 (Doença de Steinert) é uma doença multissistêmica progressiva autossômica dominante em que a crise miotônica pode ser desencadeada por vários fatores, incluindo dor, estresse emocional, hipotermia, tremores e estímulo mecânico ou elétrico. O presente relato descreve anestesia geral realizada com dexmedetomidina em combinação com peridural torácica para colecistectomia laparoscópica em paciente com Doença de Steinert. Para evitar laringoscopia, a intubação traqueal foi realizada utilizando cateter de intubação Aintree guiado por broncofibroscopia óptica. Os efeitos anestésicos prolongados do propofol foram revertidos e a recuperação anestésica foi acelerada pelo uso de infusão intravenosa de teofilina.

Evaluación del sulfato de magnesio en el tratamiento del broncoespasmo / Assessment of magnesium sulfate in bronchospasm treatment

Introducción: Una de las urgencias más temidas durante la instrumentación de la vía respiratoria es el broncoespasmo. El sulfato de magnesio, administrado por vía endovenosa, tiene un efecto broncodilatador al antagonizar los canales del calcio, inhibir la contracción muscular mediada por el calcio y favorecer la relajación del músculo liso bronquial. Objetivo: Evaluar la eficacia del sulfato de magnesio endovenoso en pacientes con broncoespasmo durante broncoscopias. Métodos: Estudio observacional, descriptivo y transversal en 20 pacientes, con broncoespasmo, desencadenado por manipulación de la vía respiratoria con broncoscopio flexible, tratados con sulfato de magnesio 50 mg/kg, (máximo 2 g), por vía endovenosa durante 5 min. Resultados: Predominaron los hombres entre 50-59 años (75 por ciento), todos los pacientes eran fumadores, 15 pacientes fueron clasificados como estado físico ASA III. Sufrieron broncoespasmo de intensidad moderada 60 por ciento, clasificado según la clínica y monitorización de SpO2. En 75 por ciento de los pacientes cedió el broncoespasmo tras el tratamiento sin administrar otro medicamento. No se registraron efectos adversos. Ningún paciente necesitó intubación orotraqueal para ventilación ni requirió hospitalización por más de 8 h. Conclusiones: El sulfato de magnesio es una buena opción farmacológica para el tratamiento de urgencia del broncoespasmo desencadenado por manipulación de la vía respiratoria(AU)

Introduction: One of the most feared emergencies during the instrumentation of the respiratory tract is bronchospasm. Magnesium sulfate, administered intravenously, has a bronchodilation effect by antagonizing calcium channels, inhibiting muscle contraction mediated by calcium and promoting bronchial smooth muscle relaxation. Objective: To evaluate the efficacy of magnesium sulfate administered intravenously in patients with bronchospasm during bronchoscopy. Methods: Observational, descriptive and cross-sectional study carried out with 20 patients, with bronchospasm, triggered by airway manipulation with flexible bronchoscope, treated with 50 mg/kg of magnesium sulfate, (maximum 2 g), administered intravenously for 5 min. Results: Men between 50-59 years (75 percent) predominated. All patients were smokers. 15 patients were classified with physical state ASA III. They suffered bronchospasm of mild intensity 60 percent, classified according to the clinic and monitoring of oxygen saturation. In 75 percent of the patients, the bronchospasm ceased after the treatment without administering any other medication. No adverse effects were recorded. No patient needed orotracheal intubation for ventilation or required hospitalization for more than 8 hours. Conclusions: Magnesium sulfate is a good pharmacological option for the emergency treatment of bronchospasm triggered by manipulation of the respiratory tract(AU)

Study on the use of CT three-dimensional reconstruction technique for guiding tracheal intubation with rigid fiber bronchoscope in difficult airway / 北京大学学报(医学版)

OBJECTIVE@#To evaluate the significance of CT three-dimensional reconstruction technique for guiding tracheal intubation with rigid fiber bronchoscope in difficult airway.@*METHODS@#In this study, 44 patients undergoing selective operation of ASA (American Society of Anesthesiologists physical status) I to II, neck stiffness, neck trauma needed braked, or severe cervical spondylosis were selected. The patients were randomly divided into two groups: 24 cases in the experimental group (group E) and 20 cases in the control group (group C). The stylets of the rigid fiber bronchoscopes were shaped according to the CT three-dimensional reconstruction images and parameters obtained before surgery. The rigid fiber bronchoscopes shaped according to the CT three-dimensional reconstruction images were used in group E, while the rigid fiber bronchoscopes with the original angles were used in group C. Tracheal intubation operations were all performed by an anesthesiologist who had more than 10 years' clinical experience and mastered in rigid endoscopic intubation techniques. The first attempt success rate and the total success rate of tracheal intubation, intubation time, blood pressure, heart rate and pulse oxygen saturation at different time points including pre-induction, immediately after intubation, 1-5 minutes after intubation, and intubation related complications within 24 hours were recorded.@*RESULTS@#The total success rate of intubation in the two groups were both 100%. The first attempt success rate of intubation was 96% in group E, and 70% in group C. The first attempt success rate of group E was higher than that of group C. The intubation time of group E was (20.7± 10.6) s, and (21.5 ± 17.6) s of group C. Group E was shorter than that of group C, but there was no significant difference (P > 0.05). RPP equaled the product of heart rate and systolic pressure, which represented the stress reaction of intubation on hemodynamics, was lower in group C at T0, T1, T2, T4 and T5 separately than that in group E, but there was no significant difference (P>0.05). There was no significant difference in tracheal intubation related complications between the two groups (P>0.05).@*CONCLUSION@#CT three-dimensional reconstruction technique has certain guiding significance in difficult tracheal intubation with rigid fiber bronchoscope in patients with fixed cervical spine.

Comparison of fiberoptic bronchoscope and video stylet during endotracheal intubation: simulation study

OBJECTIVE: The UE Video Stylet VL400-S2 (UE Medical Devices, Newton, MA, USA) and Ambu aScope (Ambu, Copenhagen, Denmark) were recently introduced rigid video stylets and single-use fiberoptic bronchoscopes, respectively. To compare the utility of the two sets of equipment, this study conducted a randomized cross-over study using a manikin. METHODS: Twenty-eight novice doctors performed tracheal intubation on an airway trainer manikin (Laerdal, Stavanger, Norway). The sequence of intubation devices was randomized. The following data were measured and recorded: time to complete tracheal intubation (primary end point), overall success rate, time to see the glottis, and time to tube passage. RESULTS: The video stylet (24 seconds; interquartile range [IQR] 18–36) showed a significantly shorter completion time of the tracheal intubation than the fiberoptic bronchoscope (43 seconds; IQR, 32–84) (P<0.001). The overall success rate of tracheal intubation was 96.4% (27/28) in the video stylet and 82.1% (23/28) in the fiberoptic bronchoscope, and the cumulative success rate over time to complete intubation was significantly higher in the video stylet (P<0.001). CONCLUSION: The video stylet was superior to the fiberoptic bronchoscope in terms of the time to complete and the cumulative success rate of intubation for novice operators in manikin model. Further research will be needed to determine the degree of education required to use fiberoptic bronchoscopy.

Identifying the ideal tracheostomy site based on patient characteristics during percutaneous dilatational tracheostomy without bronchoscopy / 대한마취과학회지

BACKGROUND: We previously reported that percutaneous dilatational tracheostomy (PDT) can be safely performed 2 cm below the cricothyroid membrane without the aid of a bronchoscope. Although our simplified method is convenient and does not require sophisticated equipment, the precise location for tracheostomy cannot be confirmed. Because it is recommended that tracheostomy be performed at the second tracheal ring, we assessed whether patient characteristics could predict the distance between the cricothyroid membrane and the second tracheal ring. METHODS: Data from 490 patients who underwent three-dimensional neck computed tomography from January 2012 to December 2015 were analyzed, and the linear distance from the upper part of the cricoid cartilage (CC) to the lower part of the second tracheal ring (2TR) was measured in the sagittal plane. RESULTS: The mean CC-to-2TR distance was 25.26 mm (95% CI 25.02–25.48 mm). Linear regression analysis showed that the predicted CC-to-2TR distance could be calculated as −5.73 + 0.2 × height (cm) + 1.22 × sex (male: 1, female: 0) + 0.01 × age (yr) −0.03 × weight (kg) (adj. R² = 0.55). CONCLUSIONS: These results suggest that height and sex should be considered when performing PDT without bronchoscope guidance.

A prospective randomized controlled double-blind study comparing auscultation and lung ultrasonography in the assessment of double lumen tube position in elective thoracic surgeries involving one lung ventilation at a tertiary care cancer institute / 대한마취과학회지

BACKGROUND: As lung ultrasound (LUS) can be used to identify regional lung ventilation and collapse, we hypothesize that LUS can be better than auscultation in assessing lung isolation and determining double lumen tube (DLT) position. METHODS: A randomized controlled study was conducted in tertiary care cancer institute from November 2014 to December 2015, including 100 adult patients undergoing elective thoracic surgeries. Patients with tracheostomy, difficult airway and pleural-based pathologies were excluded. After anesthesia induction and DLT insertion, patients were randomized into group A (auscultation) and group B (LUS). Regional ventilation was assessed by experienced anesthesiologists using the respective method for each group. Final confirmation of DLT position with a bronchoscope was performed by a blinded anesthesiologist. Contingency tables were plotted to determine sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy for each method. RESULTS: Data from 91 patients were analyzed (group A = 47, group B = 44). Compared with auscultation, LUS had significantly higher sensitivity (94.1% vs. 73.3%, P = 0.010), PPV (57.1% vs. 35.5%, P = 0.044), NPV (93.8% vs. 75.0%, P = 0.018), accuracy (70.5% vs. 48.9%, P = 0.036) and required longer median time (161.5 vs. 114 s, P < 0.001) for assessment of DLT position. Differences in specificity (55.6% vs. 37.5%, P = 0.101) and area under curve (0.748; 95% CI: 0.604–0.893 vs. 0.554, 95% CI: 0.379–0.730; P = 0.109) were not significant. CONCLUSIONS: Compared to auscultation, LUS is a superior method for assessing lung isolation and determining DLT position.

Iatrogenic Tension Pneumothorax after Surgical Tracheostomy in a Child with Idiopathic Subglottic Stenosis: case report / 고신대학교의과대학학술지

Tracheostomy is increasingly performed in children for upper airway anomalies. Here, an 18-month-old child (height 84.1 cm, weight 12.5 kg) presented to the emergency department with dyspnea, stridor, and chest retraction. However, exploration of the airways using a bronchoscope failed due to subglottic stenosis. Therefore, a surgical tracheostomy was successfully performed with manual mask ventilation. However, pneumomediastinum was found in the postoperative chest radiograph. Although an oxygen saturation of 99% was initially maintained, oxygen saturation levels dropped, due to sudden dyspnea, after 3 hours. A chest radiograph taken at this time revealed a left tension pneumothorax and small right pneumothorax. Despite a needle thoracostomy, the pneumothorax was aggravated, and cardiac arrest occurred. Cardiopulmonary-cerebral resuscitation was performed, but the patient was declared dead 30 minutes later. This study highlights the fatal complications that can occur in children during tracheostomy. Therefore, close monitoring, immediate suspicion, recognition, and aggressive management may avoid fatal outcomes.

Awake supraglottic airway guided flexible bronchoscopic intubation in patients with anticipated difficult airways: a case series and narrative review / 대한마취과학회지

Awake intubation is indicated in difficult airways if attempts at securing the airway after induction of general anesthesia may lead to harm due to potential difficulties or failure in those attempts. Conventional awake flexible bronchoscopic intubation is performed via the nasal, or less commonly, oral route. Awake oral flexible bronchoscopic intubation (FBI) via a supraglottic airway device (SAD) is a less common technique; we refer to this as ‘supraglottic airway guided’ FBI (SAGFBI). We describe ten cases with anticipated difficult airways in which awake SAGFBI was performed. After sedation and adequate airway topicalization, an Ambu Auragain™ SAD was inserted. A flexible bronchoscope, preloaded with a tracheal tube, was then inserted through the SAD. Finally, the tracheal tube was railroaded over the bronchoscope, through the SAD and into the trachea. The bronchoscope and the SAD were carefully removed, whilst keeping the tracheal tube in-situ. The technique was successful and well tolerated by all patients, and associated complications were rare. It also offered the advantages of performing an ‘awake test insertion’ of the SAD, an ‘awake look’ at the periglottic region, and an ‘awake test ventilation.’ In certain patients, awake SAGFBI offers advantages over conventional awake FBI or awake videolaryngoscopy. More research is required to evaluate its success and failure rates, and identify associated complications. Its place in difficult airway algorithms may then be further established.

Selective left mainstem bronchial intubation in the neonatal intensive care unit / Intubação seletiva do brônquio principal esquerdo em unidade de terapia intensiva neonatal

Abstract Background: Selective neonatal left mainstem bronchial intubation to treat right lung disease is typically achieved with elaborate maneuvers, instrumentation and devices. This is often attributed to bronchial geometry which favors right mainstem entry of an endotracheal tube deliberately advanced beyond the carina. Case summary: A neonate with severe bullous emphysema affecting the right lung required urgent non-ventilation of that lung. We achieved left mainstem bronchial intubation by turning the endotracheal tube 180° such that the Murphy's eye faced the left instead of the right, and simulated a left-handed intubation by slightly orientating the endotracheal tube such that its concavity faced the left instead of the right as in a conventional right-handed intubation. Conclusion: Urgent intubation of the left mainstem bronchus with an endotracheal tube can be easily achieved by recognizing that it is the position of the endotracheal tube tip and the direction of its concavity that are the chief determinants of which bronchus an endotracheal tube goes when advanced. This is important in critically ill neonates as the margin of safety and time window are small, and the absence of double-lumen tubes. Use of fiberoptic bronchoscope and blockers should be reserved as backup plans.

Resumo Justificativa: A intubação seletiva neonatal do brônquio principal esquerdo para tratar a doença pulmonar direita é tipicamente feita com elaboradas manobras, instrumentação e dispositivos. Isso é frequentemente atribuído à geometria brônquica que favorece a entrada principal direita de um tubo endotraqueal (TET) deliberadamente avançado para além da carina. Resumo do caso: Recém-nascido com enfisema bolhoso grave que afetava o pulmão direito e precisou com urgência da não ventilação desse pulmão. Para conseguir a intubação brônquica esquerda fizemos uma rotação de 180° do TET, de forma que o olho de Murphy ficasse voltado para a esquerda, e não para a direita, e para simular uma intubação à esquerda orientamos ligeiramente o TET, de modo que sua concavidade virasse para a esquerda em vez de para a direita, como em uma intubação convencional à direita. Conclusão: A intubação urgente do brônquio principal esquerdo com um TET pode ser facilmente obtida se reconhecermos que é a posição da ponta do TET e a direção de sua concavidade que determinam para qual brônquio o TET irá quando avançado. Isso é importante em neonatos criticamente doentes diante da margem de segurança e janela de tempo pequenas e na ausência de tubos de duplo lúmen. O uso de broncofibroscópio e bloqueadores deve ser considerado como planos de segurança.

Airway management in pediatric tongue flap division for oronasal fistula closure: A case report

Oronasal fistulae (ONF) could remain after surgery in some patients with cleft palate. ONF ultimately requires intraoral surgery, which may lead to perioperative airway obstruction. Tongue flap surgery is a technique used to repair ONF. During the second surgery for performing tongue flap division, the flap transplanted from the tongue dorsum to the palate of the patient acts as an obstacle to airway management, which poses a great challenge for anesthesiologists. In particular, anesthesiologists may face difficulty in airway evaluation and patient cooperation during general anesthesia for tongue flap division surgery in pediatric patients. The authors report a case of airway management using a flexible fiberoptic bronchoscope during general anesthesia for tongue flap division surgery in a 6-year-old child.

Airway management during general anesthesia in an intellectually disabled patient with undiagnosed tracheomalacia

In cases of intellectually disabled patients, there is sometimes difficult to obtain sufficient information due to the intellectual disorder, even though the patient has significant medical problems. Herein, we report a case of decreased oxygen saturation and inadequate air exchange during general anesthesia in an intellectually disabled patient. We also describe the subsequent management, including the diagnosis of tracheomalacia (TM) using bronchoscopy, and the management of airway compromise with manual and/or controlled respiration, which led to the prevention of complications.

Awake fiberoptic orotracheal intubation using a modified Guedel airway in a patient with craniocervical instability and an anticipated difficult airway: A case report

In patients with upper cervical instability, airway management may provoke subluxation of the craniocervical region and neurologic injury, and can be challenging for the anesthesiologist. Endotracheal intubation using a fiberoptic bronchoscope is frequently used in these patients to minimize spine motion, but this procedure may fail in patients with altered airway anatomy. When fiberoptic endotracheal intubation fails in these patients, optional intubation methods are limited. We describe successful awake fiberoptic orotracheal intubation using a modified Guedel airway divided in the midline for a 59-year-old man with an anticipated difficult airway, due to limited mouth opening, a nasopharyngeal tumor, and craniocervical spine instability after failure of conventional fiberoptic orotracheal intubation.

Successful airway management with combined use of McGrath® MAC video laryngoscope and fiberoptic bronchoscope in a severe obese patient with huge goiter: a case report / 대한마취과학회지

Huge goitor can lead to tracheal compression and hence difficulty in intubation. This is compounded by severe obesity. Failed tracheal intubation in difficult intubation is a serious event that may lead to increased patient morbidity and mortality. Current intubation rescue techniques and combination of different rescue techniques may increase the success rate of difficult intubation. In a 47-year-old female patient, with severe obesity and a huge goiter, our attempts at intubation using direct laryngoscope, video laryngoscope, and awake fiberoptic bronchoscope had failed. We succeeded by applying video laryngoscope to improve visualization of the airway and fiberoptic bronchoscope as a stylet for endotracheal tube.

Efficacy of early treatment via fiber bronchoscope in children with Mycoplasma pneumoniae pneumonia complicated by airway mucus obstruction / 中国当代儿科杂志

<p><b>OBJECTIVE</b>To study the efficacy of early treatment via fiber bronchoscope in children with Mycoplasma pneumoniae pneumonia (MPP) complicated by airway mucus obstruction.</p><p><b>METHODS</b>According to the time from admission to the treatment via fiber bronchoscope, the children with MPP who were found to have airway mucus obstruction under a fiber bronchoscope were randomly divided into early intervention group (≤3 days; n=40) and late intervention group (>3 days; n=56). The two groups were compared in terms of clinical data and imaging recovery.The children were followed for 1-3 months.</p><p><b>RESULTS</b>Of the 96 children, 38 were found to have the formation of plastic bronchial tree, among whom 10 were in the early intervention group and 28 were in the late intervention group (P=0.01). Compared with the late intervention group, the early intervention group had a shorter duration of fever, length of hospital stay, and time to the recovery of white blood cell count and C-reactive protein (P<0.05), as well as a higher atelectasis resolution rate (P<0.05). Compared with the late intervention group, the early intervention group had a higher percentage of children with a ≥ 60% absorbed area of pulmonary consolidation at discharge. After 3 months of follow-up, the early intervention group had a higher percentage of children with a ≥ 90% absorbed area of pulmonary consolidation than the late intervention group (80% vs 55%; P=0.01), and the early intervention group had a lower incidence rate of atelectasis than the late intervention group (P<0.05).</p><p><b>CONCLUSIONS</b>Early treatment via fiber bronchoscope can shorten the course of the disease and reduce complications and sequelae in MPP children with airway mucus obstruction.</p>

Anesthetic management with extracorporeal membrane oxygenation in a patient with acute airway obstruction after inhalation burn injury: A case report

A 36-year-old woman was admitted to the intensive care unit because of an inhalation burn injury. Five days after admission, she developed dyspnea and hypercarbia. Therefore, fiberoptic bronchoscopy was performed through the endotracheal tube, which revealed foreign bodies in the tube. Tracheostomy was performed to remove, albeit incompletely, the foreign bodies (endotracheal debris). As sudden movement of the patient or airway reaction could cause the foreign bodies to move deeper into the bronchus during manipulation of the rigid bronchoscope, general anesthesia was induced and maintained by using total intravenous anesthesia with extracorporeal membrane oxygenation (ECMO). The foreign bodies were successfully removed without any other complications. This case showed that sloughed endobronchial debris after an inhalation burn injury caused acute airway obstruction. In such cases, alternative ventilation methods such as tracheostomy and ECMO may have to be applied, which can support a surgeon to focus on the procedure regardless of prolonged procedural time.

Fiberoptic bronchoscope and C-MAC video laryngoscope assisted nasal-oral tube exchange: two case reports

In cases of multiple facial trauma and other specific cases, the anesthesiologist may be asked to convert an oral endotracheal tube to a nasal endotracheal tube or vice versa. Conventionally, the patient is simply extubated and the endotracheal tube is re-inserted along either the oral or nasal route. However, the task of airway management can become difficult due to surgical trauma or worsening of the airway condition. Fiberoptic bronchoscopy was considered a novel method of airway conversion but this method is not useful when there are secretions and bleeding in the airway, or if the anesthesiologist is inexperienced in using this device. We report a successful airway conversion under the aid of both, a fiberoptic bronchoscope and a C-MAC video laryngoscope.

Airway obstruction by dissection of the inner layer of a reinforced endotracheal tube in a patient with Ludwig's angina: A case report

Intraoperative airway obstruction is perplexing to anesthesiologists because the patient may fall into danger rapidly. A 74-year-old woman underwent an emergency incision and drainage for a deep neck infection of dental origin. She was orally intubated with a 6. 0 mm internal diameter reinforced endotracheal tube by video laryngoscope using volatile induction and maintenance anesthesia (VIMA) with sevoflurane, fentanyl (100 µg), and succinylcholine (75 mg). During surgery, peak inspiratory pressure increased from 22 to 38 cmH₂O and plateau pressure increased from 20 to 28 cmH₂O. We maintained anesthesia because we were unable to access the airway, which was covered with surgical drapes, and tidal volume was delivered. At the end of surgery, we found a longitudinal fold inside the tube with a fiberoptic bronchoscope. The patient was reintubated with another tube and ventilation immediately improved. We recognized that the tube was obstructed due to dissection of the inner layer.

The F.B. extraction center should have instruments appropiate for ages and body sizes of its population. Feeding precautions and food preparation, during first 3 years of life, must be emphasized.

A two-stage approach to induction and intubation of two infants with Pierre Robin Sequence using a LMA Classic™ and Air-Q®: two cases report / 대한마취과학회지

The laryngeal mask airway (LMA) Classic™ and Air-Q® are supralaryngeal devices used for airway management in routine and difficult pediatric airways. We describe a novel two-stage technique of insertion of the LMA Classic™ awake prior to induction of anesthesia, to assure oxygenation and ventilation, and after induction removal and placement of the Air-Q® for intubation using the flexible fiberoptic bronchoscope. The LMA Classic's™ pliable design and relatively small size allow it to be easily placed in awake infants. In contrast, the Air-Q® is an excellent device for intubation because of its larger internal diameter and removable 9 mm adapter. Our goal was to reduce unpredictability and potentially increase the safety of induction of anesthesia and intubation in infants with Pierre Robin sequence. By using these devices in a two-stage approach we created a technique for consistent oxygenation, ventilation, and intubation in these infants.
