RESUMO

Anaesthesia and positive pressure ventilation cause ventral redistribution of regional ventilation, potentially caused by the tracheal tube. We used electrical impedance tomography to map regional ventilation during anaesthesia in 10 patients with and without a tracheal tube. We recorded impedance data in subjects who were awake, during bag-mask ventilation, with the tracheal tube positioned normally, rotated 90° to each side and advanced until in an endobronchial position. We recorded the following measurements: ventilation of the right lung (proportion, %); centre of ventilation (100% = entirely ventral); global inhomogeneity (0% = homogenous); and regional ventilation delay, an index of temporal heterogeneity. We compared the results using Student's t-tests. Relative to subjects who were awake, anaesthesia with bag-mask ventilation reduced right-sided ventilation by 5.6% (p = 0.002), reduced regional ventilation delay by 1.6% (p = 0.025), and moved the centre of ventilation ventrally from 51.4% to 58.2% (p = 0.0001). Tracheal tube ventilation caused a further centre of ventilation increase of 1.3% (p = 0.009). With the tube near the carina, right-sided ventilation increased by 3.2% (p = 0.031) and regional ventilation delay by 2.8% (p = 0.049). Tube rotation caused a 1.6% increase in right-sided ventilation compared with normal position (p = 0.043 left and p = 0.031 right). Global inhomogeneity remained mostly unchanged. Ventral ventilation with positive pressure ventilation occurred with bag-mask ventilation, but was exacerbated by a tracheal tube. Tube position influenced ventilation of the right and left lungs, while ventilation overall remained homogenous. Tube rotation in either direction resulted in ventilation patterns being closer to when awake than either bag-mask ventilation or a normally positioned tube. These results suggest that even ideal tube positioning cannot avoid the ventral shift in ventilation.

RESUMO

BACKGROUND AND AIM: Accurate anesthesia management is of great importance for the success of interventional neuroangiographic procedures (INPs). General anesthesia with endotracheal intubation is the most commonly preferred anesthetic method for these procedures. However, whether laryngeal mask airway (LMA) anesthesia is a suitable and safe option for such cases is unclear. The aims of this study were to report the outcomes of anesthetic management in patients who underwent INP, and to compare endotracheal intubation with LMA anesthesia in terms of anesthesia-related outcomes. METHODS: Data of patients who underwent INP under general anesthesia at interventional neuroangiography unit were retrospectively evaluated. RESULTS: A total of 105 patients with a mean age of 52.9 years were included in the study. All procedures were performed under general anesthesia with using endotracheal tube (n = 79, 75.2%) or laryngeal mask (n = 26, 24.8%). Anesthesia-related complications, including respiratory (laryngospasm,bronchospasm, and desaturation) and circulatory (disrhythmia, hypotension, hypertension), were observed in 20 (19.1%) patients. The 2 airway instruments were similar in age, gender, diagnosis, American Society of Anesthesiologist score, mallampati score, duration of procedure, and duration of anesthesia (P > .05). Anesthesia-related complications were more common in LMA group compared with patients who were intubated using endotracheal tube (P = .003). CONCLUSIONS: Anesthesia management in INPs carries many challenges for anesthesiologists, due to the need of exact immobility during the procedure and potential procedure-related risks such as vasculary perforation and bleeding. General anesthesia using endotracheal intubation seems to be more secure, in comparison to LMA anesthesia.

RESUMO

Purpose: The aim of this study was to compare the perioperative and postoperative respiratory complications between laryngeal mask (LM) airway and tracheal intubation (TI) in children undergoing percutaneous internal ring suturing (PIRS) for inguinal hernia. Patients and Methods: From October 2015 to February 2019, 135 pediatric patients (97 males and 38 females) with median age of 4 years, who underwent PIRS for inguinal hernia, were included in study. Patients were divided in two groups. In group I (n = 94) LM airway was used, and in group II (n = 41) TI was performed. Demographic data, surgical and anesthesia times, American Society of Anesthesiologists (ASA) classification, muscle relaxation, level of pneumoperitoneum, and complications of anesthesia were compared between the groups. Results: No significant differences among compared groups regarding age (P = .435), sex (P = .306), body mass index (P = .548), ASA classification (P = .506), level of pneumoperitoneum (P = .968), and duration of surgery (P = .968) were found. Duration of anesthesia was significantly shorter when LM was used compared to TI (25 minutes versus 36 minutes; P < .00001). During recovery from anesthesia, the incidences of desaturation (n = 1 versus n = 5; P = .003), laryngospasm (n = 2 versus n = 5; P = .015), and cough (n = 0 versus n = 4; P = .002) were significantly lower when LM airway was used for securing of the airway. Postoperative incidences of sore throat (P = .543), bronchospasm (P = .128), and aspiration (P = .128) did not differ between LM and TI. Conclusions: The use of LM in pediatric anesthesia results in a decrease in a number of common complications and significantly shortened patient anesthesia time. It is therefore a valuable device for the management of the pediatric airway for laparoscopic hernia repair in children.

RESUMO

BACKGROUND: We have been using computed tomography (CT) guidance for percutaneous glycerol rhizotomy (PGR) for the last 7 years. As a quality improvement exercise, we recently began using general anesthesia (GA) with the use of a laryngeal mask airway (LMA) because of our perception that the procedure went faster and that there was less radiation exposure because of less patient movement. We aim to compare PGR radiation exposure and procedural time between patients receiving local anesthetic with sedation and those receiving GA/LMA. METHODS: A single-center historical cohort study was performed using patients treated with PGR between 2017 and 2019. Ninety-two surgeries were conducted during the study period: 64 surgeries had local anesthetic with intravenous sedation, and 28 surgeries had deeper anesthetic with LMA. Data analyzed included the number of CT sequences obtained, needle placement time, and total radiation dose. RESULTS: Use of GA/LMA resulted in a 23% decrease in mean radiation dose (565.5 vs. 436.1 µGy × cm, P = 0.014), number of CT sequences required (7.4 vs. 5.7, P = 0.003), and needle placement time (12.8 vs. 9.8 minutes, P = 0.006). Additionally, 10 patients underwent multiple glycerol rhizotomies during the collection period with both anesthetic types being used at least once. Seven of 10 patients (70.0%) had a reduction in total radiation dose, number of CT sequences obtained, and needle placement time when GA/LMA was used. There were no procedure- or anesthetic-related complications in this patient cohort. CONCLUSIONS: The use of GA/LMA during PGR is associated with decreased radiation exposure without increased anesthetic complications.

RESUMO

BACKGROUND: Age-related changes in upper airway anatomy may affect the overall performance of supraglottic airways significantly. The clinical performance of the i-gel and the self-pressurized air-Q intubating laryngeal airways with noninflatable cuffs for elderly populations remains unknown, unlike in children. Thus, we performed a prospective, randomized comparison of these 2 supraglottic airways in elderly patients undergoing general anesthesia. METHODS: We recruited 100 patients, 65-90 years of age, who were scheduled for elective surgery under general anesthesia with muscle relaxation. The enrolled patients were allocated to the i-gel or self-pressurized air-Q group. We assessed oropharyngeal leak pressure as the primary outcome and fiberoptic view after placement and fixation of the airway and at 10 minutes after the initial assessment. The fiberoptic view was scored using a 5-point scale as follows: vocal cords not visible; vocal cords and anterior epiglottis visible, >50% visual obstruction of epiglottis to vocal cords; vocal cords and anterior epiglottis visible, <50% visual obstruction of epiglottis to vocal cords; vocal cords and posterior epiglottis visible; and vocal cords visible. We also investigated success rate and ease of insertion, insertion time, and manipulations during insertion as insertion variables, complications during maintenance and emergence periods, and postoperative pharyngolaryngeal complications including sore throat, dysphagia, and dysphonia. RESULTS: After assessing for eligibility, 48 patients were allocated to each group. Oropharyngeal leak pressures were significantly higher in the i-gel group than in the self-pressurized air-Q group (P < .001) at the 2 measurement points. The raw mean difference at initial assessment and the median difference after 10 minutes were 5.5 cm H2O (95% confidence interval, 3.3-7.6 cm H2O) and 5.0 (95% confidence interval, 2.0-7.0 cm H2O), respectively. The initial scores of fiberoptic view were similar in the 2 groups. However, the self-pressurized air-Q supraglottic airway provided a significantly improved fiberoptic view at 10 minutes after initial assessment (P = .030). We found no statistically significant differences in insertion variables and complications between the 2 groups. CONCLUSIONS: The i-gel provided better sealing function than the self-pressurized air-Q supraglottic airway according to the high oropharyngeal leak pressures in elderly patients during general anesthesia. The self-pressurized air-Q supraglottic airway had improved fiberoptic views in elderly patients during general anesthesia.

RESUMO

BACKGROUND: Flexible reinforced laryngeal mask airway (FLMA®) has gained popularity in thyroid surgery, but air leak and displacement are still concerns. METHODS: In this randomized, single-blinded, noninferiority, controlled trial, we randomized patients scheduled for elective radical thyroidectomy to an endotracheal tube (ETT) group or a FLMA group. The primary outcomes were ventilation leak volume, peak airway pressure, and partial pressure of end-tidal carbon dioxide (PetCO2). Data for primary outcomes were collected after insertion of ETT/FLMA, at incision, and at 10-minute intervals during surgery. Ten milliliters, 5 cm H2O, and 10 mm Hg were used as the noninferiority deltas for ventilation leak volume, peak airway pressure, and PetCO2, respectively. We assessed noninferiority of FLMA to ETT on the primary outcomes over time using the results of a linear mixed-effects model. The position of FLMA mask was evaluated before and after surgery, and the airway complications were recorded. RESULTS: A total of 132 patients were included: 65 in ETT group and 67 in FLMA group. Differences (FLMA group minus ETT group) of ventilation leak volume, peak airway pressure, and PetCO2 from the mixed-effects models were 2.09 mL (98.3% confidence interval [CI], -6.46 to 10.64), -0.60 cm H2O (98.3% CI, -2.15 to 0.96), and 1.02 mm Hg (98.3% CI, 0.04-1.99), respectively. Score of fiber-optic position of FLMA was significantly higher after surgery than before. There was no severe shift, loss of the mask seal, regurgitation, or aspiration in the FLMA group. One patient in the FLMA group experienced brief and easily controlled laryngospasm. CONCLUSIONS: In thyroid surgery, FLMA is noninferior to ETT in the peak airway pressure and PetCO2 although mild to moderate mask shift could occur during surgical manipulation. There is no evidence for a higher complication rate when FLMA is used.

RESUMO

Data about the feasibility and safety of thoracoscopic surgery under non-intubated anesthesia and regional block are limited. In this prospective study, 57 consecutive patients scheduled for thoracoscopic surgery were enrolled. Patients were sedated with dexmedetomidine and anesthetized with propofol and remifentanil. Ropivacaine was used for intercostal nerve and paravertebral block. Lidocaine was used for vagal block. The primary outcomes were mean arterial pressure (MAP), heart rate (HR), oxygen saturation, and end-tidal carbon dioxide partial pressure (ETCO2) at T0 (pre-anesthesia), T1 (immediately after laryngeal mask/nasopharyngeal airway placement), T2 (immediately after skin incision), T3 (10 min after opening the chest), T4 (end of surgery), and T5 (immediately after laryngeal mask/nasopharyngeal airway removal). One patient required conversion to intubation, 15 developed intraoperative hypotension, and two had hypoxemia. MAP at T0 and T5 was higher than at T1-T4; MAP at T3 was lower (P<0.05 vs other time points). HR at T0 and T5 was higher (P<0.05 vs other time points). ETCO2 at T2 and T3 was higher (P<0.05 vs other time points). Arterial pH, PCO2, and lactic acid at T1 differed from values at T0 and T2 (P<0.05). The Quality of Recovery-15 (QoR-15) score at 24 h was lower (P<0.05). One patient experienced dysphoria during recovery. Thoracoscopic surgery with regional block under direct thoracoscopic vision is a feasible and safe alternative to conventional surgery under general anesthesia, intubation, and one-lung ventilation.

RESUMO

RATIONALE: Airway management of patients in a lateral decubitus position (LDP), who cannot lie supine is challenging for anesthesiologists. In a previous study, laryngeal mask airway (LMA) was found to be superior to conventional endotracheal intubation in LDP. PATIENT CONCERNS: A 38-year-old man diagnosed with type I neurofibromatosis presented with pain caused by a large hematoma (28 × 8 cm) located in the left upper back. On arrival at the operating theater, he was in a right LDP because of the aggravation of pain in the supine position. DIAGNOSES: Laryngoscopy-guided endotracheal intubation was expected to be difficult in LDP. INTERVENTIONS: After the induction of anesthesia, a non-inflatable LMA was introduced into the laryngopharynx with the patient in LDP. He was then maneuvered into a supine position and removal of the LMA was followed by endotracheal intubation. OUTCOMES: The surgery for the removal of the hematoma was performed in a prone position. The airway intubated with an endotracheal tube was well maintained during the entire surgery. LESSONS: LMA is a useful device for airway management in patients in LDP who cannot lie supine.

RESUMO

En la actualidad, el uso de los dispositivos supraglóticos (DSG) para el manejo de la vía aérea está ampliamente extendido en urgencias y emergencias por su fácil manejo. El objetivo de la presente revisión es comparar los dispositivos supraglóticos para el manejo de la vía aérea, tubo laríngeo (TL) y máscara laríngea (ML), en sus diferentes versiones, para determinar cuál de ellos reúne las mejores condiciones para un uso eficiente en la atención a urgencias y emergencias. Se realiza una revisión sistemática de la literatura a través de la consulta en 9 bases de datos bibliográficas: Biblioteca Cochrane Plus, Medline, CINAHL, Dialnet, Global Health, Nursing & Allied Health Database, CUIDEN, Web of Science y ScienceDirect. Fueron seleccionados registros que estaban comprendidos entre los años 2014 y 2019, en español, inglés, francés y portugués, donde se realizara una comparación entre los DSG, TL y ML, en sus diferentes versiones. Se identificaron un total de 18 estudios válidos tras la lectura crítica. En la mayoría de aspectos evaluados, no se apreciaron diferencias significativas entre ambos dispositivos. Destancaba una presión de sellado orofaríngeo y velocidad de inserción superior en determinados contextos en la utilización del TL, y existía además una visión menor de la glotis mediante la utilización del broncoscopio. Los diferentes contextos en que se puede presentar la utilización de los DSG y la escasez de registros que comparan el TL con las ML en sus diferentes versiones no permite una clara diferenciación en cuanto a eficacia. No obstante, sí parece evidenciarse una visión menor de la glotis en la utilización del TL tras ser valorado con el fibroscopio, factor a tener en cuenta si se tiene presente que en la atención secundaria la intubación selectiva mediante la intubación traqueal, considerada el "patrón oro", puede llegar a ser una necesidad


Various supraglottic devices are currently available for airway management and are used widely in emergency situations because they are easy to position. We undertook a systematic review of the literature comparing laryngeal tubes and various laryngeal mask airway devices (LMAs) to determine which ones can be used most efficiently in emergencies. Nine databases were searched, as follows: Cochrane Library Plus, MEDLINE, CINAHL (Cumulative Index to Nursing and Allied Health Literature), Dialnet, Global Health, Nursing & Allied Health Database, CUIDEN, the Web of Science, and ScienceDirect. We collected studies published between 2014 and 2019 in Spanish, English, French, and Portuguese that compared laryngeal tubes to LMAs of different types for supraglottic airway management. Eighteen studies were selected for analysis after critical reading. Significant differences were not seen between tubes and LMAs with respect to most variables, but in certain contexts the oropharyngeal seal and speed of insertion were superior with laryngeal tubes; however, when fiberoptic bronchoscopes were then inserted the view of the glottis was poor. The different contexts in which these devices are used and the scarcity of studies comparing laryngeal tubes to LMAs does not allow us to identify clear differences among them with respect to efficiency. However, tubes seem to offer poorer visibility of the glottis according to evaluation with fiberoptic scopes, a factor to bear in mind if tracheal intubation, which is considered the gold standard, might become necessary

RESUMO

OBJECTIVE: To compare the safety of laryngeal mask airway removal using two different deep anaesthesia techniques in paediatric patients. METHODS: The Randomized Control Trial was conducted at Aga Khan University Hospital, Karachi, from April 2012 to November 2013, and comprised patients aged 2-10 years scheduled for infraumbilical surgeries. Anaesthesia was induced with sevoflurane and later it was maintained by is oflurane, oxygen and nitrous oxide. The laryngeal mask airway was removed in the intervention group-I at 0.4 minimum alveolar concentration of isoflurane with propofol 1mg/kg. In the control group-II, it was removed at 1.2 minimum alveolar concentration of isoflurane alone. SPSS 19 was used for data analysis. RESULTS: Of the 50 patients, there were 25(50%) in each of the two groups. Overall, there were 46(92%) males and 4(8%) females. Incidence of airway obstruction and teeth clenching was significantly higher in group-II (p<0.05 each). Emergence duration was also significantly increased in group-II compared to group-I (p=0.001). The Post-Anaesthesia Care Unit stay timing was not significantly different between the groups (p=0.74). CONCLUSIONS: Laryngeal mask airway removal under deep anaesthetic technique of low-dose propofol with isoflurane was found to be associated with minimal adverse airway events than isoflurane alone in paediatric patients.

RESUMO

Awake craniotomy is a unique technique utilized for mapping neuro and motor function during neurosurgical procedures close to eloquent brain tissue. Since active communication is required only during surgical manipulation of eloquent brain tissue and the patient is "sedated" during other parts of the procedure, different methods for anesthesia management have been explored. Furthermore, airway management ranges from spontaneous breathing to oro or nasotracheal intubation. Case reports have described the use of laryngeal masks (LMs) previously; however, its safety compared to tracheal intubation has not been assessed.We conducted a retrospective analysis of 30 patients that underwent awake craniotomy for tumor surgery to compare the feasibility and safety of different airway management strategies. Nasal fiberoptic intubation (FOI) was performed in 21 patients while 9 patients received LM for airway management. Ventilation, critical events, and perioperative complications were evaluated.Cannot intubate situation occurred in 4 cases reinserting the tube after awake phase, while no difficulties were described reinserting the LM (P < .0001). Furthermore, duration of mechanical ventilation after tumor removal was significantly lower in the LM group compared to FOI group (62 ±â€Š24 vs. 339 ±â€Š82 [min] mean ±â€Šsem, P < .0001). Postoperatively, 2 patients in each group were diagnosed with and treated for respiratory complications including pneumonia, without statistical significance between groups.In summary, LM is a feasible airway management method for patients undergoing awake craniotomy, resulting in reduced ventilation duration compared to FOI procedure.

RESUMO

OBJECTIVE: To determine the frequency of reflux and aspiration in children subjected to reinforced laryngeal mask during laparoscopic surgery in the Trendelenburg position, and evaluate its feasibility. STUDY DESIGN: A descriptive study. PLACE AND DURATION OF STUDY: Department of Anesthesiology, Beijing Chaoyang Hospital, Capital Medical University, from January 2017 to May 2018. METHODOLOGY: A total of 300 children, who underwent laparoscopic high ligation of the hernial sac in the Trendelenburg position under general anesthesia, were enrolled into the present study. Reflux and aspiration were assessed by precise saliva pH to determine the pH value at laryngeal mask airway, and at sites on laryngeal mask corresponding to the larynx, face and peripheral area. Then, the presence of food residue was observed at various sites to determine whether there was reflux or aspiration during the operation. RESULTS: Suspected reflux (9.67%) was observed in 29 children and suspected aspiration was observed in nine children (3%). There was no definite reflux or aspiration observed in any of the children. Furthermore, the prevalence of suspected reflux was higher in children who were >3 years and overweight, compared to children with a normal body mass index and an age of <3 years. CONCLUSION: With strict fasting and water deprivation, and strict selection of laryngeal mask indications before selective operation, it is feasible to apply reinforced laryngeal mask in laparoscopic surgery in the Trendelenburg position in children.

RESUMO

BACKGROUND: Laryngeal masks are increasingly used in place of endotracheal intubation or face masks for maintaining the airway during surgery. OBJECTIVES: Compare the insertion time and other features of the Baska and I-gel masks in patients undergoing general anesthesia for urological surgery. DESIGN: Randomized-controlled, single-blind study. SETTINGS: Urology surgical operating rooms of a tertiary care hospital. SUBJECTS AND METHODS: We enrolled concomitant patients whose surgery was expected to last less than two hours. Following premedication and adequate relaxation, subjects were randomly allocated to the I-gel mask or the Baska mask. Computer-generated random numbers were used for randomization with sealed opaque envelopes for allocation concealment. MAIN OUTCOME MEASURES: The primary outcome measure of the study was the time required for laryngeal mask airway (LMA) insertion. Also, the number of device placement attempts, the number of postoperative signs and symptoms (cough, breath holding, laryngeal spasm, lip trauma, blood on the mask), and laryngopharyngeal morbidity scores at 1 and 24 hours postoperatively. SAMPLE SIZE: 211 met inclusion criteria, 200 participants completed the study. RESULTS: Compared to I-gel, the Baska mask required a longer time for insertion, and its airway pressure was higher. The median (minimum-maximum) duration of LMA insertion in the Baska and I-gel groups was 14 (6-25) and 7 (5-12) seconds, respectively (z=-10.934; P<.001). The mean (SD) airway pressures were significantly different between the two groups (15.8 [1.9] and 14.9 [1.7] cm/H2O for Baska and I-gel, respectively; t=3.668; P<.001). Seal pressure was not significantly different between the groups (0.08 [0.2] vs. 0.07 [0.2] cm/H2O in the Baska and I-gel groups, respectively, (t=1.35; P=.194). CONCLUSIONS: The Baska and I-gel masks are similar in most respects. Both have reasonably acceptable insertion times and can be used for selected surgical procedures. LIMITATIONS: The requirement for more vigorous training is a limitation of the Baska mask. Results could differ with patients younger than 18 years of age or obese patients. CONFLICT OF INTEREST: None. CLINICAL TRIAL REGISTRY: Not registered.
