    ABSTRACT: Objective: The aim of this study is to report a case of a clinically significant obstruction during mechanical ventilation caused by the dissection of the wired endotracheal tube's lumen during general anesthesia in a pediatric patient. Case report: A12-year old patient undergoing general anesthesia for open appendectomy was intubated with a wired endotracheal tube and difficult removal of the guide. After starting the mechanical ventilation, there was increased expiratory fraction of CO2 and need for increased inspiratory pressure. Chance of complications with higher incidences were raised and treated unsuccessfully. Finally, during patient reintubation, the dissection of the endotracheal tube lumen was observed, and ventilation was restored to normal. Conclusion: Anesthesia involves numerous possible complications. Suspicion and constant vigilance are essential for early diagnosis and treatment of any threat to the individual integrity. This case is relevant for emphasizing a possible very rare complication related to airway, which can quickly cause hypoxia and irreversible damage. Thus, this case contributes to the detection of this complication more frequently.

    ABSTRACT: Background and objectives: The introduction of propofol (2,6-diisopropylphenol) as a sedative agent has transformed the area of sedation for endoscopic procedures. However, a major drawback of sedation with the use of propofol is its high incidence of injection pain. The most widely used technique in reducing propofol injection pain is through the association of other drugs. The aim of this study was to evaluate the effect of remifentanil-propofol combination on the incidence of propofol injection pain and its influence on the total dose of propofol required for sedation in upper digestive tract endoscopy (UDE) diagnostic tests. Method: One hundred and five patients undergoing upper digestive tract endoscopy were evaluated and randomly divided into 3 groups of 35 patients each. The Control Group received propofol alone; Study-group 1 received remifentanil at a fixed dose of 0.2mg/kg combined with propofol; Study-group 2 received remifentanil at a fixed dose of 0.3mg/kg combined with propofol. The incidence of propofol injection pain and the total dose of propofol required for the test were evaluated. The sample was very similar regarding age, weight, height, sex, and physical status. Statistical analysis was performed according to the nature of the evaluated data. Student's t-test was used to compare the mean of age, weight, height (cm), and dose (mg/kg) variables between groups. The ℵ(2) test was used to compare sex, physical status, and propofol injection pain between groups. The significance level was α < 0.05. Results: There was significant statistical difference between the study groups and the control group regarding the parameters of propofol injection pain and total dose of propofol (mg/kg) used. However, there were no statistical differences between the two study groups for these parameters. Conclusion: We conclude that the use of remifentanil at doses of 0.2mg/kg and 0.3mg/kg was effective for reducing both the propofol injection pain and the total dose of propofol used.

    ABSTRACT: The ex utero intrapartum treatment (EXIT) procedure consists of partial externalization of the fetus from the uterine cavity during delivery, allowing the maintenance of placental circulation. It is indicated in the presence of congenital malformation when difficulty in fetal airway access is anticipated, allowing it to be ensured by direct laryngoscopy, bronchoscopy, tracheostomy, or surgical intervention. Anesthesia for EXIT procedure has several special features, such as the appropriate uterine relaxation, maintenance of maternal blood pressure, fetal airway establishment, and maintenance of postpartum uterine contraction. The anesthesiologist should be prepared for the anesthetic particularities of this procedure in order to contribute to a favorable outcome for the mother and particularly the fetus.

    ABSTRACT: Takotsubo cardiomyopathy (TCM) is a stress-induced cardiomyopathy. It is characterized by an acute onset of symptoms and electrocardiographic abnormalities mimicking an acute coronary syndrome in the absence of obstructive coronary artery disease. Any anesthetic-surgical event corresponds to a stressful situation, so the anesthetic management of patients with TCM requires special care throughout the perioperative period. We describe the anesthetic management of a patient with a confirmed diagnosis of TCM undergoing segmental colectomy. Female patient, 55 years old, ASA III, with history of takotsubo syndrome diagnosed 2 years ago, scheduled for segmental. The patient, without other changes in preoperative evaluation, underwent general anesthesia associated with lumbar epidural and remained hemodynamically stable during the 2hours of surgery. After a brief stay in the Post-Anesthesia Care Unit, she was transferred to the Intermediate Care Unit (IMCU), with epidural analgesia for postoperative period. TCM is a rare disease whose true pathophysiology remains unclear, as well as the most appropriate anesthetic-surgical strategy. In this case, through a preventive approach, with close monitoring and the lowest possible stimulus, all the perioperative period was uneventful. Because it is a rare disease, this report could help to raise awareness about TCM. Copyright © 2015 Sociedade Brasileira de Anestesiologia. Publicado por Elsevier Editora Ltda. All rights reserved.

    ABSTRACT: Ludwig's angina (LA) is an infection of the submandibular space, first described by Wilhelm Frederick von Ludwig in 1836. It represents an entity difficult to manage due to the rapid progression and difficulty in maintaining airway patency, a major challenge in medical practice, resulting in asphyxia and death in 8-10% of patients. Describe a case of a patient with Ludwig's angina undergoing surgery, with emphasis on airway management, in addition to reviewing the articles published in the literature on this topic. Male patient, 21 years, drug addict, admitted by the emergency department and diagnosed with LA. Difficult airway was identified during the anesthetic examination. In additional tests, significant deviation from the tracheal axis was seen. Undergoing bilateral thoracoscopic pleural drainage, we opted for airway management through tracheal intubation using fiberoptic bronchoscopy, and balanced general anesthesia was proposed. There were no complications during the surgical-anesthetic act. After the procedure, the patient remained intubated and mechanically ventilated in the intensive care unit. Airway management in patients with Ludwig's angina remains challenging. The choice of the safest technique should be based on clinical signs, technical conditions available, and the urgent need to preserve the patient's life.

    ABSTRACT: The use of tranexamic acid in primary total knee replacement surgeries has been the subject of constant study. The strategies to reduce bleeding are aimed at reducing the need for blood transfusion due to the risks involved. In this study we evaluated the use of tranexamic acid in reducing bleeding, need for blood transfusion, and prevalence of postoperative deep vein thrombosis (DVT) in primary total knee replacement. 62 patients undergoing primary total knee replacement were enrolled in the study, from June 2012 to May 2013, and randomized to receive a single dose of 2.5g of intravenous tranexamic acid (Group TA) or saline (Group GP), 5minutes before opening the pneumatic tourniquet, respectively. Hemoglobin, hematocrit, and blood loss were recorded 24hours after surgery. DVT was investigated during patient's hospitalization and 15 and 30 days after surgery in review visits. There was no demographic difference between groups. Group TA had 13.89% decreased hematocrit (p=0.925) compared to placebo. Group TA had a decrease of 12.28% (p=0.898) in hemoglobin compared to Group GP. Group TA had a mean decrease of 187.35mL in blood loss (25.32%) compared to group GP (p=0.027). The number of blood transfusions was higher in Group GP (p=0.078). Thromboembolic events were not seen in this study. Tranexamic acid reduced postoperative bleeding without promoting thromboembolic events. Copyright © 2015 Sociedade Brasileira de Anestesiologia. Publicado por Elsevier Editora Ltda.

    ABSTRACT: Takotsubo cardiomyopathy, also known as broken heart syndrome is a stress-induced cardiomyopathy, which can be interpreted as an acute coronary syndrome as it progresses with suggestive electrocardiographic changes. The purpose of this article is to show the importance of proper monitoring during surgery, as well as the presence of an interdisciplinary team to diagnose the syndrome. Male patient, 66 years old, with diagnosis of gastric carcinoma, scheduled for diagnostic laparoscopy and possible gastrectomy. In the intraoperative period during laparoscopy, the patient always remained hemodynamically stable, but after conversion to open surgery he presented with ST segment elevation in DII. ECG during surgery was performed and confirmed ST-segment elevation in the inferior wall. The cardiology team was contacted and indicated the emergency catheterization. As the surgery had not yet begun irreversible steps, we opted for the laparotomy closure, and the patient was immediately taken to the hemodynamic room where catheterization was performed showing no coronary injury. The patient was taken to the hospital room where an echocardiogram was performed and showed slight to moderate systolic dysfunction, with akinesia of the mid-apical segments, suggestive of apical ballooning of the left ventricle. Faced with such echocardiographic finding and in the absence of coronary injury, the patient was diagnosed with intraoperative Takotsubo syndrome. Because the patient was properly monitored, the early detection of ST-segment elevation was possible. The presence of an interdisciplinary team favored the syndrome early diagnosis, so the patient was again submitted to safely intervention, with the necessary security measures taken for an uneventful new surgical intervention.

    ABSTRACT: The objective of this study was to evaluate how Brazilian anesthesiologists are using neuromuscular blockers (NMB), focusing on how they establish the diagnosis of postoperative residual curarization and the incidence of complications associated with the use of NMB. A questionnaire was sent to anesthesiologists inviting them to participate in the study. The online data collection remained open from March 2012 to June 2013. During the study period, 1296 responses were collected. Rocuronium, atracurium, and cisatracurium were the main neuromuscular blockers used in cases of elective surgery. Succinylcholine and rocuronium were the main NMB used in cases of emergency surgery. Less than 15% of anesthesiologists reported the frequent use of neuromuscular function monitors. Only 18% of those involved in the study reported that all workplaces have such a monitor. Most respondents reported using only the clinical criteria to assess whether the patient is recovered from the muscle relaxant. Most respondents also reported always using some form of neuromuscular blockade reversal. The major complications attributed to NMB were residual curarization and prolonged blockade. Eighteen anesthesiologists reported death attributed to NMB. Residual or prolonged blockade is possibly recorded as a result of the high rate of using clinical criteria to diagnose whether the patient has recovered or not from motor block and, as a corollary, the poor use of neuromuscular transmission monitors in daily practice.

    ABSTRACT: The burn patient is a challenge for the anesthesiologist, undergoing several surgeries during admission, and requiring general anesthesia and muscle relaxation most of the times. They have respiratory system impairment and a response to muscle relaxants that differs from the healthy patient, thus proper monitoring and reversal is crucial. We analyzed sugammadex effectiveness and safety in this population. Prospectively descriptive study including four patients, all of them considered major burn patients, who underwent escharotomy with general anesthesia and neuromuscular relaxation. The main variable was the time for recovery of a TOF higher than 0.9 after the administration of sugammadex before extubation. Mean time of recovery from a TOF ratio higher than 0.9 following the administration of Sugammadex was of 4.95minutes 95% CI (3.25-6.64, p=.53); CONCLUSIONS: The reversion of neuromuscular relaxation with sugammadex appears to be effective and safe in the burn patient. More analytical, comparative studies, of larger populations would be necessary to confirm this data. Copyright © 2015 Sociedade Brasileira de Anestesiologia. Publicado por Elsevier Editora Ltda.

    ABSTRACT: Review of various techniques for digital blocks with local anesthetic, with or without epinephrine. Description of various procedures and comparison of results reported in the literature, mainly on latency and quality of anesthesia, details on vasoconstrictor effect of epinephrine, intraoperative bleeding, necessity of tourniquet use, duration of anesthesia and postoperative analgesia, blood flow and digital SpO2 behavior, local and systemic complications, and also approaches and drugs to be used in certain situations of ischemia. The advantages of adding epinephrine to the anesthetic solution are minor when compared to the risks of the procedure, and it seems dangerous to use a vasoconstrictor in the fingers, unless the safety of the technique and the possibility of discarding the tourniquet are definitely proven.

    ABSTRACT: We report the case of a 25-year-old woman, who received epidural analgesia for labour pain and subsequently presented post-dural puncture headache. Conservative treatment was applied and epidural blood patch was performed. In the absence of clinical improvement and due to changes in the postural component of the headache, a brain imaging test was performed showing a bilateral subdural hematoma. The post-dural puncture headache is relatively common, but the lack of response to established medical treatment as well as the change in its characteristics and the presence of neurological deficit, should raise the suspicion of a subdural hematoma, which although is rare, can be lethal if not diagnosed and treated at the right time.

    ABSTRACT: Anaphylaxis remains one of the potential causes of perioperative death, being generally unanticipated and quickly progressing to a life-threatening situation. A review of perioperative anaphylaxis is performed. The diagnostic tests are important mainly to avoid further major events. The mainstays of treatment are adrenaline and intravenous fluids. The anesthesiologist should be familiar with the proper diagnosis, management and monitoring of perioperative anaphylaxis. Copyright © 2014 Sociedade Brasileira de Anestesiologia.

    ABSTRACT: Multiple sclerosis is a demyelinating disease of the brain and spinal cord, characterized by muscle weakness, cognitive dysfunction, memory loss, and personality disorders. Factors that promote disease exacerbation are stress, physical trauma, infection, surgery, hyperthermia. The objective is to describe the anesthetic management of a case referred to urological surgery. A female patient, 44 years of age, with multiple sclerosis, diagnosed with nephrolithiasis, referred for endoscopic ureterolythotripsy. Balanced general anesthesia was chosen, with midazolam, propofol and remifentanil target-controlled infusion; sevoflurane via laryngeal mask airway; and spontaneous ventilation. Because the patient had respiratory difficulty presenting with chest wall rigidity, it was decided to discontinue the infusion of remifentanil. There was no other complication or exacerbation of disease postoperatively. The use of neuromuscular blockers (depolarizing and non-depolarizing) is a problem in these patients. As there was no need for muscle relaxation in this case, muscle relaxants were omitted. We conclude that the combination of propofol and sevoflurane was satisfactory, not resulting in hemodynamic instability or disease exacerbation.

    ABSTRACT: The increased prevalence of obesity in the general population extends to women of reproductive age. The aim of this study is to report the perioperative management of a morbidly obese pregnant woman, body mass index > 50 kg/m(2), who underwent cesarean section under general anesthesia. Pregnant woman in labor, 35 years of age, body mass index 59.8 kg/m(2). Caesarean section was indicated due to the presumed fetal macrosomia. The patient refused spinal anesthesia. She was placed in the ramp position with cushions from back to head to facilitate tracheal intubation. Another cushion was placed on top of the right gluteus to create an angle of approximately 15° to the operating table. Immediately before induction of anesthesia, asepsis was carried out and sterile surgical fields were placed. Anesthesia was induced in rapid sequence, with Sellick maneuver and administration of remifentanil, propofol, and succinilcolina. Intubation was performed using a gum elastic bougie, and anesthesia was maintained with sevoflurane and remifentanil. The interval between skin incision and fetal extraction was 21 minutes, with the use of a Simpson's forceps scoop to assist in the extraction. The patient gave birth to a newborn weighing 4850 g, with Apgar scores of 2 in the 1(st) minute (received positive pressure ventilation by mask for about 2 minutes) and 8 in the 5(th) minute. The patient was extubated uneventfully. Multimodal analgesia and prophylaxis of nausea and vomiting was performed. Mother and newborn were discharged on the 4(th) postoperative day.

    ABSTRACT: burnout syndrome is a result of chronic stress, characterized by emotional exhaustion, depersonalization, and sense of low professional accomplishment. It affects workers under extreme responsibility or those who care for individuals at risk, including anesthesiologists who distanced themselves from the work, patients and colleagues because they feel safer in maintaining indifference. evaluate the prevalence of burnout syndrome and the intensity of its components and identify the characteristics of those with the syndrome among anesthesiologists in the Federal District. cross-sectional study with 241 anesthesiologists enrolled in the Society of Anesthesiology of the Federal District. A self-administered questionnaire was used, which included the Maslach Burnout Inventory, demographic, professional, and leisure data. of the 134 completed questionnaires (55.8%), there was a predominance of male (65.6%), aged 30-50 years (67.9%). Significant lower levels of job satisfaction (47.7%), depersonalization (28.3%), and emotional exhaustion (23.1%) were found. Burnout syndrome showed a prevalence of 10.4%, occurring mainly in men (64.2%), aged 30-50 years (64.2%), with over ten years of experience (64.2%), working in night shifts (71.4%), sedentary (57.1%), and not taking courses unrelated to medicine (78.5%). Of the participants, 50.7% had at least one of three criteria to develop the syndrome and only 8.2% have a low risk to manifest it. the prevalence of burnout is relevant among anesthesiologists in the Federal District. It is advisable to seek strategies for labor restructuring to reduce stress factors and loss of motivation and increase job satisfaction. Copyright © 2014 Sociedade Brasileira de Anestesiologia.

    ABSTRACT: studies have shown that rate of propofol infusion may influence the predicted propofol concentration at the effect site (Es). The aim of this study was to evaluate the Es predicted by the Marsh pharmacokinetic model (ke0 0.26min(-1)) in loss of consciousness during fast or slow induction. the study included 28 patients randomly divided into two equal groups. In slow induction group (S), target-controlled infusion (TCI) of propofol with plasma, Marsh pharmacokinetic model (ke0 0.26min(-1)) with target concentration (Tc) at 2.0-μg.mL(-1) were administered. When the predicted propofol concentration at the effect site (Es) reached half of Es value, Es was increased to previous Es + 1μg.mL(-1), successively, until loss of consciousness. In rapid induction group (R), patients were induced with TCI of propofol with plasma (6.0μ at Es, and waited until loss of consciousness. in rapid induction group, Tc for loss of consciousness was significantly lower compared to slow induction group (1.67±0.76 and 2.50±0.56μg.mL(-1), respectively, p=0.004). the predicted propofol concentration at the effect site for loss of consciousness is different for rapid induction and slow induction, even with the same pharmacokinetic model of propofol and the same balance constant between plasma and effect site.

    ABSTRACT: Cuffs of tracheal tubes protect the lower airway from aspiration of gastric contents and facilitate ventilation, but may cause many complications, especially when the cuff pressure exceeds 30cm H2O. This occurs in over 30% of conventional insufflations, so it is recommended to limit this pressure. In this study we evaluated the in vitro effectiveness of a method of limiting the cuff pressure to a range between 20 and 30cm H2O. Using an adapter to connect the tested tube to the anesthesia machine, the relief valve was regulated to 30cm H2O, inflating the cuff by operating the rapid flow of oxygen button. There were 33 trials for each tube of three manufacturers, of five sizes (6.5 to 8.5), using three times inflation (10, 15 and 20seconds), totaling 1485 tests. After inflation, the pressure obtained was measured with a manometer. Pressure >30cm H2O or <20cm H2O were considered failures. There were eight failures (0.5%, 95% CI: 0.1-0.9%), with all by pressures <20cm H2O and after 10seconds inflation (1.6%, 95% CI: 0 5-2.7%). One failure occurred with a 6.5 tube (0.3%, 95% CI: -0.3-0.9%), six with 7.0 tubes (2%, 95% CI: 0.4 to 3.6%), and one with a 7.5 tube (0.3%, 95% CI: -0.3-0.9%). This method was effective for inflating tracheal tube cuffs of different sizes and manufacturers, limiting its pressure to a range between 20 and 30cm H2O, with a success rate of 99.5% (95% CI: 99.1-99.9%).
