RESUMO

The intubating laryngeal mask airway (ILMA) can be used for ventilation and oxygenation between intubation attempts, but there is a varied success rate ranging from 33% to 96%. Air Q is a relatively new entrant. Parker flex tube aids in atraumatic intubation. The primary aim of this study was to compare Air Q intubating laryngeal airway with ILMA as intubation conduits in patients with simulated fixed cervical spine using a Parker flex tube. It was a single-blinded, randomized, prospective, and comparative study conducted on 91 patients aged between 18 to 60 years of either sex, scheduled to undergo elective surgery under general anesthesia belonging to the American Society of Anesthesiologists physical status I and II. Out of 45 patients in each group, Air Q was successfully placed in 43 patients and ILMA was successfully placed in 44 patients. 35.56% of the patients required maneuvers for placing the Air Q, whereas, for placing the ILMA, only 15.56% of the patients required maneuvers. Intubation through the AIR Q was successful in 39 patients and through the ILMA in 44 patients, but there was no significant difference between the two groups. The number of attempts and the time of device insertion were comparable. There were a similar number of attempts, maneuvers required, and time is taken for endotracheal intubation. The incidence of cough and sore throat was comparable in both groups. We conclude that ILMA has a higher success rate than Air Q for tracheal intubation with Parker Flex tube in patients with simulated fixed cervical spine. More optimized maneuvers were required for the placement of Air Q.

RESUMO

OBJECTIVE: Airway management has undergone a dramatic transformation since the arrival of video laryngoscope (VL). VL has higher intubation success rate on first try and lower complications in comparison to direct laryngoscope (DL). The use of VL is recommended in intubating COVID-19 patients to speed up intubation time and reduce failure rate. A team from Airlangga University developed Wycope Video Laryngoscope (Wycope VL), a VL with Wi-Fi connection to smartphones for an easier VL with low cost. This study aimed to compare the effectiveness of Wycope VL, C-MAC Video Laryngoscope (C-MAC VL), and DL. MATERIALS AND METHODS: This study was an analytic observational study with a cross sectional design, involving 63 patients who were divided into 3 groups based on the type of laryngoscope, namely Wycope VL, C-MAC VL, and DL. Intubation is carried out by 4th year anaesthesiology resident. Research subjects were patients who will undergo elective surgery at Dr. Soetomo General Hospital under general anaesthesia using orotracheal tube. Inclusion age of 19-64 years, PS ASA 1-2, no anatomical abnormalities of the airway, did not have difficult airway, and was willing to participate in the study. RESULTS: All patients were successfully intubated without complications. C-MAC VL (5.33±1.42 seconds) and Wycope VL (5.95±0.74 seconds) was significantly faster in seeing vocal folds and glottis compared to DL (7.14±0.72 seconds) with P=0.000. DL was significantly faster in average time of intubation (15.52±5.90 seconds) compared to C-MAC VL (16.95±1.11 seconds) and Wycope VL (20.29±2.81 seconds) with P=0.000. CONCLUSION: DL was faster compared to VL in speed of intubation while C-MAC VL and Wycope VL was faster in viewing the vocal folds and glottis compared to DL.

RESUMO

There are different results on the effect of endotracheal tube (ETT) size on respiratory mechanics in patients undergoing mechanical ventilation, and there are few reports in adult laparoscopic surgery. The aim of this study was to investigate the effect of ETT size on airway resistance (RAW) and dynamic lung compliance (COMPL) in patients undergoing laparoscopic colorectal surgery. Seventy-two patients undergoing laparoscopic radical surgery for colorectal cancer under general anesthesia with endotracheal intubation were selected and divided into 3 groups (n = 24) using the random number table method Group A (ETT ID 7.0), Group B (ETT ID 7.5), and Group C (ETT ID 8.0). After mechanical ventilation, intraoperative RAW and COMPL were monitored in each of the 3 groups. In the non-pneumoperitoneal state, RAW in group ID7.0 is significantly higher than this in group ID7.5 and group ID8.0 (P < .05); the RAW between the 2 groups with ID7.5 and ID8.0 was not statistically significant (P > .05). The difference of COMPL between the 3 groups was statistically significant (P < .05); the COMPL of Group ID7.0 is lower than Group ID7.5, and Group ID7.5 is lower than Group ID8.0. In the pneumoperitoneal state, the RAW between ID7.0 group and ID8.0 group was statistically significant, the RAW difference between ID7.0 group and ID7.5 group, ID7.5 group and ID8.0 group not statistically significant (P > .05);the COMPL between the 3 groups was not statistically significant (P > .05). In the non-pneumoperitoneal state, the smaller the ETT internal diameter within a certain range, the higher RAW and the lower COMPL; in the pneumoperitoneal state, the RAW with the ID7.0 ETT was higher than that with the ID8.0 ETT, and the ETT size within a certain range had no effect on COMPL.

RESUMO

RATIONALE: Gastric tube implantation is a routine part of preoperative preparation. Indwelling gastric tubes in patients under general anesthesia maintain gastrointestinal decompression and prevent gastrointestinal expansion. PATIENT CONCERNS: Gastric tube insertion can be associated with many complications, of which gastric tube knotting is a rare and often overlooked complication. DIAGNOSES: Knotting together of gastric and tracheal tubes. INTERVENTIONS: During the operation, the gastric tube was explored by endoscope and hand. LESSONS: Rare complications of knotted gastric and endotracheal tubes are identified and treated promptly. CONCLUSION: We recommend that the gastric tube be intubated first before insertion of the endotracheal tube, and visualization tools should be used in time if the insertion of the gastric tube is unsuccessful.

RESUMO

Mechanical ventilation is a lifesaving treatment used to treat critical neonatal patients. It facilitates gas exchange, oxygenation, and CO2 removal. Despite advances in non-invasive ventilatory support methods in neonates, invasive ventilation (i.e., ventilation via an endotracheal tube) is still a standard treatment in NICUs. This ventilation approach may cause injury despite its advantages, especially in preterm neonates. Therefore, it is recommended that neonatologists consider weaning neonates from invasive mechanical ventilation as soon as possible. This review examines the steps required for the neonate's appropriate weaning and safe extubation from mechanical ventilation.

RESUMO

BACKGROUND: Tracheoesophageal fistula (TEF) is a rare but life-threatening complication after esophagectomy. A new gastrointestinal occluder device provides treatment for TEF patients. However, TEF-related pneumonia and respiratory failure increase the difficulty of anesthesia management, especially in airway management. CASE PRESENTATION: A 64-year-old man with thoracic esophageal cancer underwent esophagectomy and gastric tube reconstruction one year ago. The patient presented with recurrent cough and sputum after surgery. Gastroscopy revealed a fistula between the esophagogastric anastomotic site and membrane of the trachea. Therefore, the patient received implantation of a new gastrointestinal occluder device under gastroscopy combined with tracheoscopy. Airway management under general anesthesia was discussed with an interdisciplinary decision, and cuffed endotracheal tube with an inner diameter of 5.5 mm was chosen. This airway management ensured adequate oxygenation during the operation and provided sufficient space for the operation of the tracheoscope in the trachea. Finally, the TEF disappeared after the operation, and the patient was administered an oral diet on the first postoperative day. CONCLUSIONS: The implantation of a new gastrointestinal occluder device under gastroscopy combined with tracheoscopy provides a new treatment for TEF patients. This case report suggests that it is important to select an endotracheal tube with an appropriate inner diameter that can not only meet the requirements of ventilation but also does not affect the operation of tracheoscopy in the trachea.

RESUMO

Ventilator-associated pneumonia (VAP) is a prevalent nosocomial illness in mechanically ventilated patients. Hence, the aim of this study was to investigate the pattern of antibiotic resistance and biofilm formation of bacterial profiles from Endotracheal Tubes of patients hospitalized in an intensive care unit in southwest Iran. According to the standard operating method, the microbiological laboratory conducts bacteria culture and susceptibility testing on endotracheal Tube samples suspected of carrying a bacterial infection. The Clinical and laboratory standards institute (CLSI) techniques are used to determine the Antimicrobial resistance (AMR) of bacterial isolates to antibiotics using the disk diffusion method. The crystal violet staining method was used to assess the biofilm-forming potential of isolates in a 96-well microtiter plate. In total, (51%) GPBs were included in this study. The isolated GPB were coagulase-negative Staphylococcus (16%), S. aureus (14%). In total, (40%) of GNB were included in this study. The isolated GNB were Klebsiella spp. (36%), A. baumannii (22%), P. aeruginosa (35%). (32%) bacterial strains were MDR and (29%) strains were XDR. The results of biofilm formation showed (72%) were biofilm producers. VAP is a common and severe nosocomial infection in mechanically ventilated patients. Controlling biofilm formation, whether on the ET or in the oropharyngeal cavity, is thus an important technique for treating VAP. Colistin and linezolid are antibiotics that are effective against practically all resistant GNB and GPB isolates.

RESUMO

BACKGROUND: Inserting a double-lumen endotracheal tube (DLT) poses more challenge than inserting a single-lumen tube. The C-MAC D-blade videolaryngoscope is a useful alternative to the direct laryngoscope. However, no study has compared its performance with that of the McCoy laryngoscope, which has a hyperangulated blade tip similar to that of the C-MAC D-blade. We aimed to compare the performance of the C-MAC D-blade videolaryngoscope with that of the McCoy laryngoscope in DLT intubation. METHODS: In this prospective randomized controlled study, 90 patients requiring DLT intubation were randomly allocated to either the C-MAC D-blade videolaryngoscope group (group C, n = 47) or McCoy laryngoscope group (group M, n = 43). During intubation, the percentage of glottic opening, modified Cormack-Lehane grade, time taken for intubation, malposition of the bronchial lumen, and hemodynamic parameters were recorded. After intubation, we assessed the intubation difficulty scale score and, a postoperative sore throat in the recovery room. RESULTS: The time taken for intubation was 35.85 ±â€…10.77 seconds and 33.18 ±â€…11.97 seconds in groups C and M, respectively (P = .269). The modified Cormack-Lehane grade was significantly lower in group C than in group M (P = .000). Percentage of glottic opening was significantly higher in group C (79.36 ±â€…13.42%) than in group M (53.49 ±â€…29.83%) (P = .000). The intubation difficulty scale score was significantly lower in group C than in group M (P = .030). There were no significant differences between the 2 groups in terms of malposition status, hemodynamic parameters, or visual analog scale score for a postoperative sore throat. CONCLUSION: Although the time taken for intubation was comparable between the 2 intubation devices, the C-MAC D-blade videolaryngoscope facilitated glottis visualization and reduced the intubation difficulty scale better than the McCoy laryngoscope in patients undergoing DLT intubation.

RESUMO

Background: PTX3 is an important mediator of inflammation and innate immunity. We aimed at assessing its prognostic value in a large cohort of patients hospitalized with COVID-19. Methods: Levels of PTX3 were measured in 152 patients hospitalized with COVID-19 at San Gerardo Hospital (Monza, Italy) since March 2020. Cox regression was used to identify predictors of time from admission to in-hospital death or mechanical ventilation. Crude incidences of death were compared between patients with PTX3 levels higher or lower than the best cut-off estimated with the Maximally Selected Rank Statistics Method. Results: Upon admission, 22% of the patients required no oxygen, 46% low-flow oxygen, 30% high-flow nasal cannula or CPAP-helmet and 3% MV. Median level of PTX3 was 21.7 (IQR: 13.5-58.23) ng/ml. In-hospital mortality was 25% (38 deaths); 13 patients (8.6%) underwent MV. PTX3 was associated with risk of death (per 10 ng/ml, HR 1.08; 95%CI 1.04-1.11; P<0.001) and death/MV (HR 1.04; 95%CI 1.01-1.07; P=0.011), independently of other predictors of in-hospital mortality, including age, Charlson Comorbidity Index, D-dimer and C-reactive protein (CRP). Patients with PTX3 levels above the optimal cut-off of 39.32 ng/ml had significantly higher mortality than the others (55% vs 8%, P<0.001). Higher PTX3 plasma levels were found in 14 patients with subsequent thrombotic complications (median [IQR]: 51.4 [24.6-94.4] versus 21 [13.4-55.2]; P=0.049). Conclusions: High PTX3 levels in patients hospitalized with COVID-19 are associated with a worse outcome. The evaluation of this marker could be useful in prognostic stratification and identification of patients who could benefit from immunomodulant therapy.

RESUMO

INTRODUCTION: Rapid sequence intubation (RSI) is an advanced airway technique to perform endotracheal intubation in patients at high risk of aspiration. Although RSI is recognised as a life-saving technique and performed by many physicians in various settings (emergency departments, intensive care units), there is still a lack of consensus on various features of the procedure, most notably patient positioning. Previously, experts have commented on the unique drawbacks and benefits of various positions and studies have been published comparing patient positions and how it can affect endotracheal intubation in the context of RSI. The purpose of this systematic review is to compile the existing evidence to understand and compare how different patient positions can potentially affect the success of RSI. METHODS AND ANALYSIS: We will use MEDLINE, EMBASE and the Cochrane Library to source studies from 1946 to 2021 that evaluate the impact of patient positioning on endotracheal intubation in the context of RSI. We will include randomised control trials, case-control studies, prospective/retrospective cohort studies and mannequin simulation studies for consideration in this systematic review. Subsequently, we will generate a Preferred Reporting Items for Systematic Reviews and Meta-Analyses flow diagram to display how we selected our final studies for inclusion in the review. Two independent reviewers will complete the study screening, selection and extraction, with a third reviewer available to address any conflicts. The reviewers will extract this data in accordance with our outcomes of interest and display it in a table format to highlight patient-relevant outcomes and difficulty airway management outcomes. We will use the Risk of Bias tool and the Newcastle-Ottawa Scale to assess included studies for bias. ETHICS AND DISSEMINATION: This systematic review does not require ethics approval, as all patient-centred data will be reported from published studies. PROSPERO REGISTRATION NUMBER: CRD42022289773.

RESUMO

We conducted a proof of concept study where Anapnoguard endotracheal tubes and its control unit were used in 15 patients with COVID-19 acute respiratory distress syndrome. Anapnoguard system provides suction, venting, rinsing of subglottic space and controls cuff pressure detecting air leakage through the cuff. Alpha-amylase and pepsin levels, as oropharyngeal and gastric microaspiration markers, were assessed from 85 tracheal aspirates in the first 72 h after connection to the system. Oropharyngeal microaspiration occurred in 47 cases (55%). Episodes of gastric microaspiration were not detected. Patient positioning, either prone or supine, did not affect alpha-amylase and pepsin concentration in tracheal secretions. Ventilator-associated pneumonia (VAP) rate was 40%. The use of the AG system provided effective cuff pressure control and subglottic secretions drainage. Despite this, no reduction in the incidence of VAP has been demonstrated, compared to data reported in the current COVID-19 literature. The value of this new technology is worth of being evaluated for the prevention of ventilator-associated respiratory tract infections.

RESUMO

BACKGROUND: Endotracheal tube with an inflated cuff was used to manage and maintain the airway during general anesthesia in children. When the lateral pressure exerted by an inflated Endotracheal tube cuff on tracheal mucosa exceeds capillary perfusion pressure, patients may complain of cough, sore throat, and hoarseness in the postoperative period. This study aimed to assess the effect of a tracheal tube cuff filled with alkalinized lidocaine versus air on hemodynamic parameter changes during extubation and post-operative airway morbidity in children. METHODS: Institutional based observational prospective cohort study was conducted among 56 elective children; aged 3-13 years, who underwent operation under general anesthesia with cuffed endotracheal intubation for greater than one hour by grouping into the air (group1) and alkalinized Lidocaine (group2) at Tikur Anbessa specialized Hospital. Hemodynamic parameters (Heart rate and Blood pressure) and other variables were measured starting from 5 min before extubation to 24th hours after extubation of the endotracheal tube. A Comparison of numerical variables between study group was done with an independent t-test. Data were expressed in terms of mean ± standard deviation. Categorical data were assessed by Chi-square tests. RESULTS: Postoperative Sore throat was lower in alkalinized lidocaine group compared to the air group. The mean heart rate at five minutes after extubation was significantly lower in alkalinized lidocaine group (107.29 ± 6.457 beat per minute (bpm)) compared to the air group (122.04 ± 8.809 bpm), with P ≤ 0.001. Systolic blood pressure was also significantly lower in alkalinized lidocaine group (99.64 ± 8.434 millimeters of mercury (mmHg)) compared to the air group (108.21 ± 11.902 mmHg), p = 0.016 at five minutes after extubation. CONCLUSION: Alkalinized lidocaine inflated tracheal tubes have shown improved hemodynamic and laryngotracheal morbidities in children.

RESUMO

INTRODUCTION: Tracheal intubation during anesthesia can be facilitated by the neuromuscular blocking agent cisatracurium. However, limited data exists about onset time, duration of action and effect on intubating conditions in elderly patients above 80 years of age. We hypothesized that elderly patients would present a longer onset time and duration of action compared to younger adults. METHODS: This prospective observational study included 31 young (18-40 years) and 29 elderly (≥ 80 years) patients. Patients were given fentanyl 2 µg/kg and propofol 1.5-2.5 mg/kg for induction of anesthesia and maintained with remifentanil and propofol. Monitoring of neuromuscular function was performed with acceleromyography. Primary outcome was onset time defined as time from injection of cisatracurium 0.15 mg/kg (based on ideal body weight) to a train-of-four (TOF) count of 0. Other outcomes included duration of action (time to TOF ratio ≥ 0.9), intubation conditions using the Fuchs-Buder scale and the Intubating Difficulty Scale (IDS), and occurrence of hoarseness and sore throat postoperatively. RESULTS: Elderly patients had significantly longer onset time compared with younger patients; 297 seconds (SD 120) vs. 199 seconds (SD 59) (difference: 98 seconds (95% CI: 49-147), P < 0.001)). Duration of action was also significantly longer in elderly patients compared with younger patients; 89 minutes (SD 17) vs. 77 minutes (SD 14) (difference: 12 minutes (95% CI: 2.5-20.5) P = 0.01)). No difference was found in the proportion of excellent intubating conditions (Fuchs-Buder); 19/29 (66%) vs 21/31 (68%) (P = 0.86) or IDS score (P = 0.74). A larger proportion of elderly patients reported hoarseness 24 hours postoperatively; 62% vs 34% P = 0.04. CONCLUSION: In elderly patients cisatracurium 0.15 mg/kg had significantly longer onset time and duration of action compared with younger patients. No difference was found in intubating conditions at a TOF count of 0. TRIAL REGISTRATION: Clinicaltrials.gov (NCT04921735, date of registration 10 June 2021).

RESUMO

Upper airway collapsibility after anaesthesia induction may be associated with unpredictable difficult airway. However, most works on airway anatomy are tended to morphological description before anaesthesia. This study aimed to evaluate the changes of upper airway after anaesthesia induction and using pre-anesthetic ultrasound measurements to predict Difficult Laryngoscopy (DL). We included 104 eligible subjects with complete data, who were performed tracheal intubations under general anaesthesia in the study. The upper airway changes before and after anaesthesia induction were determined by seven neck ultrasound measurements, included as follow: (1) Distance from skin to under surface of Tongue (DT), (2) Thickness of the thickest part of Tongue body (TT), (3) Hyoid Mental Distance (HMD), (4) Depth of Hyoid (DH), (5) Width of Hyoid (WH), (6) Distance from Skin to Epiglottis (DSE), (7) Depth of the anterior combination of the Vocal Cords (DVC). DL was evaluated with Cormack-Lehane (CL). Data regarding HMD [from 45.3 (42.4-48.5) to 41.1 (38.5-44.9) mm], DH [from 8.7 (6.6-10.9) to 7.0 (5.3-9.1) mm], DSE [from 20.1 (16.6-22.5) to 19.5 (16.5-21.6) mm] and the DVC [from 7.1 (5.7-8.3) to 6.8 (5.7-7.9) mm] were decreased (P < 0.05), while the DT [from 15.9 (13.1-18.4) to 17.4 (14.5-19.8) mm] was increased (P > 0.05) after anaesthesia induction. Additionally, when cut-off value of DSE was 21.25 mm before anaesthesia, it may be better predicted to DL [sensitivity 80.0% (95% CI: 60.7-91.6%) and specificity 83.8% (95% CI: 73.0-91.0%)]. The upper airway after induction showed the propensity of collapsibility by ultrasound measurements. Compared with other indicators, the DSE assessed by ultrasound might be considered to a valuable predictor of DL.Trial registration: The study was registered in ClinicalTrials.gov on 23th Jan 2019, ChiCTR1900021123.

RESUMO

BACKGROUND: Evidence regarding the timing of the application of mechanical ventilation among patients with severe coronavirus disease (COVID-19) is insufficient. This systematic review and meta-analysis aimed to evaluate the effectiveness of early intubation compared to late intubation in patients with severe and critical COVID-19. METHODS: For this study, we searched the MEDLINE, EMBASE, and Cochrane databases as well as one Korean domestic database on July 15, 2021. We updated the search monthly from September 10, 2021 to February 10, 2022. Studies that compared early intubation with late intubation in patients with severe COVID-19 were eligible for inclusion. Relative risk (RR) and mean difference (MD) were calculated as measures of effect using the random-effects model for the pooled estimates of in-hospital mortality, intensive care unit (ICU) length of stay (LOS), duration of mechanical ventilation (MV), hospital LOS, ICU-free days, and ventilator-free days. Subgroup analysis was performed based on the definition of early intubation and the index time. To assess the risk of bias in the included studies, we used the Risk of Bias Assessment tool for Non-randomized studies 2.0. RESULTS: Of the 1523 records identified, 12 cohort studies, involving 2843 patients with severe COVID-19 were eligible. There were no differences in in-hospital mortality (8 studies, n = 795; RR 0.91, 95% CI 0.75-1.10, P = 0.32, I2 = 33%), LOS in the ICU (9 studies, n = 978; MD -1.77 days, 95% CI -4.61 to 1.07 days, P = 0.22, I2 = 78%), MV duration (9 studies, n = 1,066; MD -0.03 day, 95% CI -1.79 to 1.72 days, P = 0.97, I2 = 49%), ICU-free days (1 study, n = 32; 0 day vs. 0 day; P = 0.39), and ventilator-free days (4 studies, n = 344; MD 0.94 day, 95% CI -4.56 to 6.43 days, P = 0.74, I2 = 54%) between the early and late intubation groups. However, the early intubation group had significant advantage in terms of hospital LOS (6 studies, n = 738; MD -4.32 days, 95% CI -7.20 to -1.44 days, P = 0.003, I2 = 45%). CONCLUSION: This study showed no significant difference in both primary and secondary outcomes between the early intubation and late intubation groups. Trial registration This study was registered in the Prospective Register of Systematic Reviews on 16 February, 2022 (registration number CRD42022311122).

RESUMO

Tracheal intubation in primary health care is a necessary skill and usually one that is necessary for appropriate emergency management of unstable patients. Primary care practitioners may not have an anaesthetist or critical care doctor available to help them in these emergencies and must manage these patients themselves. Often tracheal intubation may fail because of multiple possible factors and a different course of action may be needed to minimise the potential for harm to the patient. The primary care professional or family physician will have to manage this failed intubation. Primary health care facilities providing obstetric services must have guidelines and appropriate equipment for management of airway problems. This article will explore reasons for the failure of tracheal intubation and how this can be managed.

RESUMO

BACKGROUND: Airway management of patients with direct airway trauma caused by penetrating neck injuries is always challenging. When a failed airway occurs and surgery access is difficult, it is crucial to find the optimal approach to save the life. We propose the concept "Cannot intubate, Cannot oxygenate, Difficult surgery access" to describe this emergency scenario. CASE PRESENTATION: We report a case of a 24-year-old woman who presented with partial tracheal rupture and pneumothorax caused by a knife stab injury to the neck. A "double setup" strategy, simultaneous preparation for orotracheal intubation and tracheotomy, was carried out before rapid sequence induction. A tracheotomy under local anesthesia or an awake intubation was not preferred in consideration that the patient had a high risk of being uncooperative owing to existing mental disease and potential smothering sensation during operation. During rapid sequence intubation, distal part of the tube penetrates the tear and creates a false lumen outside the trachea then a failed airway subsequently occurred. Rescue tracheotomy was successfully performed by an otolaryngology surgeon, with the help of limited ventilation using sequential bag-mask and laryngeal mask airway ventilation provided by an anesthesiologist, without severe sequelae. CONCLUSIONS: The endotracheal tube have a risk of penetrating the tear outside the trachea in patient with partial tracheal rupture during orotracheal intubation, and once it occurs, proceeding directly to an emergency invasive airway access with optimizing oxygenation throughout procedure might increase the chance of success in rescuing the airway.
