Project description:PurposeThis study investigated the feasibility and efficacy of continuous noninvasive ventilation (NIV) support with 100% oxygen using a specially designed face mask, for reducing desaturation during fiberoptic bronchoscopy (FOB)-guided intubation in critically ill patients with respiratory failure.Materials and methodsThis was a single-center prospective randomized study. All patients undergoing FOB-guided nasal tracheal intubation were randomized to bag-valve-mask ventilation or NIV for preoxygenation followed by intubation. The NIV group were intubated through a sealed hole in a specially designed face mask during continuous NIV support with 100% oxygen. Control patients were intubated with removal of the mask and no ventilatory support.ResultsWe enrolled 106 patients, including 53 in each group. Pulse oxygen saturation (SpO2) after preoxygenation (99% (96%-100%) vs. 96% (90%-99%), p = .001) and minimum SpO2 during intubation (95% (87%-100%) vs. 83% (74%-91%), p < .01) were both significantly higher in the NIV compared with the control group. Severe hypoxemic events (SpO2 < 80%) occurred less frequently in the NIV group than in controls (7.4% vs. 37.7%, respectively; p < .01).ConclusionsContinuous NIV support during FOB-guided nasal intubation can prevent severe desaturation during intubation in critically ill patients with respiratory failure.Trial registrationClinicalTrials.gov, NCT02462668.

Project description:BackgroundNasotracheal intubation is associated with a risk of epistaxis. Decongestion of the nasal mucosa reduces the risk of epistaxis, and different vasoconstrictors may be used. Cocaine has both decongestive and analgesic properties, but it also has side effects. In this systematic review, we aimed to evaluate if cocaine decreases the occurrence and severity of epistaxis when administered topically to the nasal mucosa before nasotracheal intubation.MethodsWe conducted a systematic review and meta-analysis following the PRISMA guidelines based on a predefined protocol. We included randomized clinical trials comparing nasal cocaine to active comparators or placebo for nasotracheal intubation. Two reviewers independently screened studies for eligibility and performed data extraction. Relative risk with 95% confidence intervals was calculated. Predefined primary outcome measures were the occurrence and severity of epistaxis. Secondary outcomes were pain, mechanical complications, and patient-centered side effects. The risk of bias was evaluated using the revised Cochrane Risk of Bias 2 tool for randomized trials, and certainty of evidence on outcome level was assessed according to GRADE.ResultsSix trials (n = 457) were included; one trial was judged as having a low risk of bias. All six trials provided information on the occurrence of epistaxis. The meta-analysis did not support a difference in the occurrence of epistaxis between cocaine and its comparators (fixed effect: relative risk 0.90 [95% confidence interval 0.75 to 1.09, I2 of 0%, certainty of evidence: low]). The severity of epistaxis was evaluated on incompatible scales and thus not suitable for meta-analysis. No studies reported on pain or mechanical complications associated with nasotracheal intubation, and data on patient-centered side effects were sparse.ConclusionThis systematic review with meta-analysis demonstrated that the quantity and certainty of evidence on cocaine used for nasotracheal intubation is low and that there is no firm evidence for the benefits and harms of cocaine compared to other vasoconstrictors and topical analgetics or placebo. Consequently, sufficiently powered randomized trials assessing patient-centered outcomes, including outcomes on side effects, should be conducted before firm conclusions on cocaine for nasotracheal intubation can be drawn.Editorial commentEpistaxis can occur with nasotracheal intubation, and topical drug vasoconstrictor effects have been used to reduce this risk. This analysis shows that the evidence base supporting the use of cocaine for reducing the risk of epistaxis in nasotracheal intubation is uncertain.

Project description:Ectodermal dysplasias are a rare group of heritable disorders involving the ectodermal derivatives with only a few published reports involving its anaesthetic management. We present the case of a 16-year-old boy with ectodermal dysplasia presented for elective oral surgery under general anaesthesia with a surgeon preference for nasotracheal intubation to provide adequate surgical exposure. The patient had successful nasal flexible bronchoscopic intubation despite challenging tracheal intubation conditions. We summarise previous case reports and discuss anaesthetic considerations in ectodermal dysplasia , including reduced mucus production in the respiratory tract, laryngeal incompetence, potential for difficult tracheal intubation and hyperthermia from reduced or absent sweat glands.

Project description:Background: Intubation of neonates is difficult and hazardous. Factors associated with procedure-related adverse events and unsuccessful intubation attempts are insufficiently evaluated, especially during neonatal nasotracheal intubations. Objective: Aim of this study was to determine the frequency of tracheal intubation-associated events (TIAEs) during neonatal nasotracheal intubations and to identify factors associated with TIAEs and unsuccessful intubation attempts in our neonatal unit. Methods: This was a prospective, single-site, observational study from May 2017 to November 2019, performed at a tertiary care neonatal intensive care unit in a German academic teaching hospital. All endotracheal intubation encounters performed by the neonatal team were recorded. Results: Two hundred and fifty-eight consecutive intubation encounters in 197 patients were analyzed. One hundred and forty-eight (57.4%) intubation encounters were associated with at least one TIAE. Intubation inexperience (<10 intubation encounters) (OR = 2.15; 95% CI, 1.257-3.685) and equipment problems (OR = 3.43; 95% CI, 1.12-10.52) were predictive of TIAEs. Intubation at first attempt (OR = 0.10; 95% CI, 0.06-0.19) and videolaryngoscopy (OR = 0.47; 96% CI, 0.25-0.860) were predictive of intubation encounters without TIAEs. The first intubation attempt was commonly done by pediatric residents (67.8%). A median of two attempts were performed until successful intubation. Restricted laryngoscopic view (OR = 3.07; 95% CI, 2.08-4.53; Cormack-Lehane grade 2 vs. grade 1), intubation by pediatric residents when compared to neonatologists (OR = 1.74; 95% CI, 1.265-2.41) and support by less experienced neonatal nurses (OR = 1.60; 95% CI, 1.04-2.46) were associated with unsuccessful intubation attempts. Conclusions: In our unit, TIAEs and unsuccessful intubation attempts occurred frequently during neonatal nasotracheal intubations. To improve success rates, quality improvement und further research should target interprofessional education and training, equipment problems and videolaryngoscopy.

Project description:The present study was designed and carried out aiming to evaluate the effects of local dexmedetomidine (Dex) on sedation rate and hemodynamic changes in candidate patients for fiberoptic nasotracheal intubation.Candidate patients for fiberoptic nasotracheal intubation were randomly divided into three groups including intravenous (IV) Dex group, local Dex group, and control group. Local anesthesia using lidocaine was performed in all patients. After performing the intubation, propofol infusion was used to keep the patients on predetermined cerebral state index (CSI). Hemodynamic parameters, arterial blood O2 saturation (SpO2), and CSI were monitored in all patients before, during, and after the procedure. Coughing score, intubation score, and patient tolerance score during and after nasotracheal intubation were assessed. Propofol consumption was also measured.A total of 95 patients with the mean age of 45.4 ± 6.7 years were evaluated (54.2% of females). Hemodynamic parameters and SpO2 were significantly different between the three groups (P < 0.001). The dose of propofol used for reaching proper CSI was significantly higher in the control group compared to IV and local Dex groups (P < 0.001). There is no significant statistical difference in propofol consumption between local and IV Dex groups. The number of patients who were cooperative during intubation was higher in local Dex group compared to IV Dex and control groups; however, the difference was not statistically significant.It is likely that using local Dex during fiberoptic bronchoscopy decreases sudden changes in hemodynamic values and decreases coughing and improves patient tolerance and intubation scores. Local Dex can be useful as IV form with the aim of propofol dose saving.

Project description:BackgroundNasotracheal intubation is commonly used in oral and maxillofacial surgeries due to its improved access to the surgical field. However, the technique can lead to complications like epistaxis and mucosal injuries. The choice of tube and other equipment may impact patient outcomes. This review aims to explore how different tubes and equipment affect patient outcomes during nasotracheal intubation.MethodsIn accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) statement, we plan to carry out a scoping review of studies examining the impact of different tubes and equipment on patient outcomes during nasotracheal intubation in adults. We will assess study design, population, type of tube and equipment, and patient outcomes across the included studies.ResultsWe plan to provide descriptive analyses of the included studies accompanied by tabulated results to summarize key findings and identify patterns in the data.ConclusionThis scoping review will summarize the existing evidence on how tube and equipment choices affect patient outcomes during nasotracheal intubation.

Project description:BackgroundAwake fiberoptic tracheal intubation is an established method of securing difficult airways, but there are some reservations about its use because many practitioners find it technically complicated, time-consuming, and unpleasant for patients. Our main goal was to test the safety and efficacy of a 300-mm working length fiberscope (video rhino-laryngoscope) when used for awake nasotracheal intubation in difficult airway cases.MethodsThis was a prospective, single-center study involving adult patients, having an ASA physical status between I and IV, with laryngopharyngeal pathology causing distorted airway anatomy. Awake nasotracheal intubation, using topical anesthesia and light sedation, was performed using a 300 mm long and 2.9 mm diameter fiberscope equipped with a lubricated reinforced endotracheal tube. The primary outcomes were the success and duration of the procedure. Patients' periprocedural satisfaction and other incidents were recorded.ResultsWe successfully intubated all 25 patients included in this study. The mean ±SD duration of the procedure, starting from the passage of the intubating tube through one of the nostrils until the endotracheal intubation, was 76 ± 36 seconds. Most of the patients showed no discomfort during the procedure with statistical significance between the No reaction Group with the Slight grimacing Group (95%CI 0.13, 0.53, p = 0.047) and the Heavy grimacing Group (95%CI 0.05, 0.83, p = 0.003). The mean ±SD satisfaction score 24 hours post-intervention was 1.8 ± 0.86 - mild discomfort. No significant incidents occurred.ConclusionsOur study showed that a 300-mm working length flexible endoscope is fast, safe, and well-tolerated for nasotracheal awake intubation under challenging airways.

Project description:ObjectiveIn this study, a north polar tube (Portex® North Polar tube [Ivory PVC Portex tube; Smiths Medical International, Hythe, United Kingdom]) (NPT) and spiral tube (ST) were compared for their ability to provide a nasal airway in patients during maxillofacial surgery.MethodsPatients who were aged 18 to 65 years with American Society of Anaesthesiologists score 1 to 2 and Mallampati score 1 to 2 were included in the study. The anesthesia technique was standardized in all patients. Patients were divided into 2 groups randomly: the NPT (n = 35) and ST groups (n = 35). Anesthesia was administered with 1% to 2% sevoflurane and a mixture of 50% oxygen + 50% air in both groups. The mean arterial pressure and heart rate values of preinduction; preintubation; and the first, second, third, and fifth minutes of intubation were recorded. Epistaxis, intraoral bleeding, cuff burst, use of Magill pens, duration of intubation, intubation difficulty, laryngeal compression, head position change, and glottic grade were evaluated.ResultsThere were no significant differences between groups in terms of demographic data (gender, age, height, weight, body mass index, American Society of Anaesthesiologists score, and Mallampati score). Macintosh laryngoscopes were used during intubation in all patients. There was no significant difference between groups in terms of intubation difficulty, duration of intubation, use of Magill pens, and determination of the glottic grade (P > 0.05). Epistaxis was significantly lower in the NPT group than in the ST group (P = 0.012). Intraoral bleeding was significantly higher in the ST group than in the NPT group (P = 0.001). During intubation, laryngeal compression (Sellick maneuver) and head position changes were significantly lower in the NPT group than in the ST group (P = 0.003 and P < 0.001, respectively). There were no significant differences in mean arterial pressure and heart rate between the 2 groups.ConclusionsWe conclude that the NPT was associated with less epistaxis and manipulations such as laryngeal compression and head position changes when compared with the ST during nasotracheal intubation. The velvet-soft polyvinyl chloride material of the NPT appears to be responsible for this advantage.

Project description:We report three cases of airway management with elective surgical cricothyroidotomy (SCT) for anesthetic management during surgical repair of maxillofacial injury involving basal skull fracture or nasal-bone fracture. In all patients, general anesthesia was induced, a supraglottic airway (SGA) device inserted, and SCT performed. Tracheal intubation was performed through SCT site, and the SGA device was removed. After surgery of maxillofacial fixation, the SGA device was re-inserted and the tracheal tube was removed. No major complications, such as subglottic stenosis or voice change, occurred. SCT holds potential as an alternative to tracheostomy because of ease of performance, fewer complications, and better cosmetic outcomes.
