Comparação de diferentes testes para determinar intubação difícil em pacientes pediátricos

BackgroundThe difficulties with airway management is the main reason for pediatric anesthesia‐related morbidity and mortality.ObjectiveTo assess the value of modified Mallampati test, Upper‐Lip‐Bite test, thyromental distance and the ratio of height to thyromental distance to predict difficult intubation in pediatric patients.DesignProspective analysis.Measurements and resultsData were collected from 5 to 11 years old 250 pediatric patients requiring tracheal intubation. The Cormack and Lehane classification was used to evaluate difficult laryngoscopy. Sensitivity, specificity, positive predictive value and AUC values for each test were measured.ResultsThe sensitivity and specificity of modified Mallampati test were 76.92% and 95.54%, while those for ULBT were 69.23% and 97.32%. The optimal cutoff point for the ratio of height to thyromental distance and thyromental distance for predicting difficult laryngoscopy was 23.5 (sensitivity, 57.69%; specificity, 86.61%) and 5.5 cm (sensitivity, 61.54%; specificity, 99.11%). The modified Mallampati was the most sensitive of the tests. The ratio of height to thyromental distance was the least sensitive test.ConclusionThese results suggested that the modified Mallampati and Upper‐Lip‐Bite tests may be useful in pediatric patients for predicting difficult intubation.     

Protocolo para avaliação física em portadores de síndrome de fibromialgia

IntroductionFibromyalgia Syndrome (FMS) is a chronic disease that causes pain and fatigue, presenting a negative impact on quality of life. Exercise helps maintaining physical fitness and influences directly on the improvement of quality of life.ObjectiveDevelop a protocol for health-related physical fitness assessment of patients with FMS with tests that are feasible and appropriate for this population.MethodAn exploratory and analytical literature review was performed, seeking to determine the tests used by the scientific community. With this in mind, we performed a literature revision through the use of virtual libraries databases: PubMed, Bireme, Banco de Teses e Dissertações da Capes and Biblioteca Digital Brasileira de Teses e Dissertações, published in between 1992-2012.ResultsA variety of tests was found; the following, by number of citations, stood out: Body Mass Index (BMI) and bioimpedance; 6-minute walk; handgrip strength (dynamometer, 1 RM [Repetition Maximum]); Sit and reach and Shoulder flexibility; Foot Up and Go, and Flamingo balance.ConclusionThese are the tests that should make up the protocol for the physical evaluation of FMS patients, emphasizing their ease of use.     

Estudo randomizado e controlado de uma intervenção terapêutica grupal em pacientes com síndrome fibromiálgica

ObjectiveTo evaluate the efficacy of a weekly interdisciplinary program (WIP) consisted of educational activities, physical therapy, stretching, ergonomics, posture guidance combined with cognitive behavioral strategies and approaches to psychosocial and occupational factors in order to determine whether this intervention would be effective to short and medium‐term improvement of symptoms in these patients.MethodsThis was a single‐center study, randomized single blind controlled trial with a sample test group (T), with a diagnosis of FMS (n = 12), and a control group (C) subjected to Pain Clinic referral (n = 15). The instruments used at two different times were the Fibromyalgia Impact Questionnaire (FIQ), Visual Analogue Scale (VAS) and Post‐Sleep Protocol (PSI). To assess quality of life, we used the SF‐12.ResultsIn samples, both groups were predominantly female, mean age of 42.5 ± 9.8 years, 43% married, average schooling of 8.3 ± 4.5 years. It was reported a mean of 4.2 years pain and an average of two years for the diagnosis of SFM from the group T. There was statistical difference between the groups in terms of efficacy post intervention WIP, in almost all outcome measures.ConclusionIt was found that weekly interdisciplinary program (WIP) has contributed to improving the quality of life of patients with fibromyalgia.     

Correlação entre os formatos da orofaringe e hipofaringe e posicionamento em intubação endotraqueal difícil

Background and objectivePrediction of intubation difficulty can save patients from major preoperative morbidity or mortality. The purpose of this paper is to assess the correlation between oro–hypo pharynx position, neck size, and length with endotracheal intubation difficulty. The study also explored the diagnostic value of Friedman Staging System in prediction cases with difficult intubation.MethodThe consecutive 500 ASA (I, II) adult patients undergoing elective surgery were evaluated for oro and hypopharynx shape and position by modified Mallampati, Cormack and Lehane score as well as Friedman obstructive sleep apnea classification systems. Neck circumference and length were also measured. All cases were intubated by a single anesthesiologist who was uninformed of the above evaluation and graded intubation difficulty in visual analog score. Correlation between these findings and difficulty of intubation was assessed. Sensitivity, Specificity, Positive and Negative Predictive Values were also reported.ResultsCormack–Lehane grade had the strongest correlation with difficulty of intubation followed by Friedman palate position. Friedman palate position was the most sensitive and had higher positive and negative predictive values than modified Mallampati classification. Cormack–Lehane grade was found to be the most specific with the highest negative predictive value among the four studied classifications.ConclusionFriedman palate position is a more useful, valuable and sensitive test compared to the modified Mallampati screening test for pre‐anesthetic prediction of difficult intubation where its involvement in Multivariate model may raise the accuracy and diagnostic value of preoperative assessment of difficult airway.     

Analgesia neuraxial em uma parturiente com síndrome de Vacterl em trabalho de parto normal

Introduction

The term VACTERL is an acronym for an association of congenital malformations: including vertebral, anal, cardiac, tracheo‐esophageal, renal and limb anomalies. VACTERL anomalies pose a formidable challenge to anesthesiologists. We describe the anesthetic management of a parturient with VACTERL association, who underwent neuraxial analgesia for labor and vaginal delivery.

Correlação entre síndrome da apneia obstrutiva e via aérea difícil na cirurgia otorrinolaringológica

Introduction

ENT patients with obstructive sleep apnea syndrome have a tendency of collapsing the upper airways in addition to anatomical obstacles. Obstructive sleep apnea syndrome is related to the increased risk of difficult airway and also increased perioperative complications. In order to identify these patients in the preoperative period, the STOP Bang questionnaire has been highlighted because it is summarized and easy to apply.

Associação entre síndrome de burnout e ansiedade em residentes e anestesiologistas do Distrito Federal

Background and objective

There is a shortage of studies addressing the association between burnout syndrome and anxiety among anesthesiologists. Identifying the relationship between these two conditions is of fundamental importance for the prevention, follow‐up, and treatment of the professionals. Thus, we evaluated the association between burnout syndrome and anxiety in anesthesiologists and residents of anesthesiology in the Federal District.

Comparação de videolaringoscópio com canal e máscara laríngea na intubação traqueal de pacientes obesos: estudo clínico randomizado

BackgroundObesity causes various difficulties in intubation and ventilation, which are confronted due to increased fat tissue in the upper airway and diminished compliance in the chest wall. Videolaryngoscopes and Intubating Laryngeal Mask Airway (ILMA) are good options as recommended by the American Society of Anesthesologists (ASA) difficult airway guidelines. We aimed to compare ILMA and Airtraq (a channeled videolaryngoscope) in obese patients.MethodsEighty patients with ASA physical status I‐III, aged between 18 and 65 years and with a body mass index greater than 35 kg.m^‐2, who were undergoing elective surgery requiring orotracheal intubation, were included in the study. Patients were intubated with one of the devices cited.ResultsThere was no difference between the number of intubation attempts, insertion times and need for optimisation manoeuvres of Airtraq and ILMA. The intubation with Airtraq was accomplished in a shorter period of time than in that in the ILMA group (29.9 ± 22.1 s vs. 50.7 ± 21.2 s; p < 0.001). A significant difference was found when the times of total intubation were compared (29.9 ± 22.1 s vs. 97.4 ± 42.7 s; p < 0.001). The mean arterial pressure statistically increased after device insertion in the ILMA group (p < 0.05).ConclusionsAirtraq appears to be superior to ILMA in obese patients, with a total of time intubation of less than 60 seconds and with low mean arterial pressure changes. However, ILMA is still a useful tool that provides both ventilation and intubation throughout the whole intubation process.     

Simulação de manejo de via aérea difícil para residentes: estudo comparativo prospectivo

Background and objectivesProcedural simulation training for difficult airway management offers acquisition opportunities. The hypothesis was that 3 hours of procedural simulation training for difficult airway management improves: acquisition, behavior, and patient outcomes as reported 6 months later.MethodsThis prospective comparative study took place in two medical universities. Second‐year residents of anesthesiology and intensive care from one region participated in 3 h procedural simulation (intervention group). No intervention was scheduled for their peers from the other region (control). Prior to simulation and 6 months later, residents filled‐out the same self‐assessment form collecting experience with different devices. The control group filled‐out the same forms simultaneously. The primary endpoint was the frequency of use of each difficult airway management device within groups at 6 months. Secondary endpoints included modifications of knowledge, skills, and patient outcomes with each device at 6 months. Intervention cost assessment was provided.Results44 residents were included in the intervention group and 16 in the control group. No significant difference was observed for the primary endpoint. In the intervention group, improvement of knowledge and skills was observed at 6 months for each device, and improvement of patient outcomes was observed with the use of malleable intubation stylet and Eschmann introducer. No such improvement was observed in the control group. Estimated intervention cost was 406€ per resident.ConclusionsA 3 h procedural simulation training for difficult airway management did not improve the frequency of use of devices at 6 months by residents. However, other positive effects suggest exploring the best ratio of time/acquisition efficiency with difficult airway management simulation.ClinicalTrials.gov IdentifierNCT02470195.     

Síndrome de Horner transitória após bloqueio paravertebral em injeção única

Background

Thoracic paravertebral block can provide analgesia for unilateral chest surgery and is associated with a low complication rate. Horner syndrome also referred to as oculosympathetic paresis, is a classic neurologic constellation of ipsilateral blepharoptosis, pupillary miosis, and facial anhidrosis resulting from disruption of the sympathetic pathway supplying the head, eye, and neck.

Sedação com dexmedetomidina e remifentanil em anestesia local para monitoração intraoperatória da fala: um relato de caso

Background and objective

Some surgical procedures such as laryngoplasty require patients to remain conscious during the intraoperative phase in order to enable speech monitoring. Dexmedetomidine and remifentanil were used in this study, since they promote appropriate patient collaboration with facilitated awakening, and are rapidly eliminated.

Uso de videolaringoscópio para intubação traqueal em paciente com massa tumoral na cavidade oral: relato de caso

Background and objectivesWhen planning the management of a predicted difficult airway, it is important to determine which strategy will be followed. Video laryngoscopy is a major option in scenarios with factors suggesting difficult airway access. It is also indicated in rescue situations, when there is tracheal intubation failure with direct laryngoscopy. The objective of the present report was to show the efficacy of using the video laryngoscope as the first device for a patient with a large tumor that occupied almost the entire anterior portion of the oral cavity.Case report85 year‐old male patient, 162 cm, 70 kg, physical status ASA II, Mallampati IV classification, was scheduled for resection of an angiosarcoma located in the right maxillary sinus that invaded much of the hard palate and the upper portion of the oropharynx. He was conscious and oriented, with normal blood pressure, heart and respiratory rates and, despite the large tumor in the oral cavity; he showed no signs of respiratory failure or airway obstruction. After intravenous cannulation and monitoring, sedation was performed with 1 mg of intravenous midazolam, and a nasal cannula was placed to provide oxygen, with a flow of 2 L.min^‐1. Then, the target‐controlled infusion of remifentanil with an effect site concentration of 2 ng.mL^‐1 was initiated, according to Minto's pharmacokinetic model. Ventilation was maintained spontaneously during airway handling. A trans cricothyroid block was performed, with 8 mL of 1% lidocaine solution injected into the tracheal lumen. Slight bleeding did not prevent the use of an optical method for performing tracheal intubation. The entire oral cavity was sprayed with 1% lidocaine. The McGraph video laryngoscope with the difficult intubation blade was used, and an armored tube with a guide wire inside was used for tracheal intubation, performed on the first attempt with appropriate glottis visualization.ConclusionThe video laryngoscope occupies a prominent position in cases in which access to the airway is difficult. In the present case it was useful. It can be used as first choice or as a rescue technique. The video laryngoscope is an appropriate alternative and should be available for facing the ever‐challenging difficult airway patient.     

Lesão do nervo mandibular bilateral após ventilação com máscara: um relato de caso

Background and objectives

Nerve injury following mask ventilation is a rare but serious anesthetic complication. The majority of reported cases are associated with excessive pressure applied to the face mask, long duration of mask ventilation, excessive digital pressure behind the mandible to relieve airway obstruction and pressure exerted by the plastic oropharyngeal airway.

Anestesia para cesárea em gestante com síndrome de Cockayne: relato de caso

Cockayne syndrome is an autosomal recessive multi‐systemic disorder due to DNA repair failure. It was originally described in 1936 in children of small stature, retinal atrophy and deafness, characterized by dwarfism, cachexia, photosensitivity, premature aging and neurologic deficits. The most typical feature is described as birdlike facies: protruding maxilla, facial lipoatrophy, sunken eyes, large ears and thin nose. Difficult airway management with subglottic stenosis and risk of gastric content aspiration has been described. Although the clinical characteristics of Cockayne syndrome have been well described in pediatric publications, there is only one report in the literature on anesthesia for an obstetric patient. We report the case of a pregnant patient diagnosed with Cockayne syndrome, submitted successfully to spinal anesthesia for a cesarean section due to cephalopelvic disproportion. In view of the difficult decision between inducing general anesthesia in a patient with a likely difficult airway, or neuraxial anesthesia in a patient with cardiovascular, respiratory and neurocognitive limitations, we suggest tailored management to reach the best results for the mother and newborn.
