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: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: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.

Project description:We evaluated the performance of the McGrath video laryngoscope and Pentax Airway Scope in comparison with the Macintosh laryngoscope for nasotracheal intubation in paediatric patients. For this, 108 patients were enrolled in an open-label, randomized controlled trial. Patients were randomly allocated to one of three groups based on use of the Macintosh laryngoscope, McGrath video laryngoscope, or Pentax Airway Scope. Time to intubation, the intubation difficulty, and the quality of navigation were compared among groups. The median nasotracheal intubation time [interquartile range] in the Macintosh group (33.5 [28.3-39.8] s) was significantly shorter than those of the McGrath (39.0 [32.0-43.0] s) and Pentax groups (43.0 [35.0-52.0] s). The difficulty of nasotracheal intubation was similar among all groups. When navigating and aligning the tube from the oropharynx into the glottic inlet, the cuff inflation method was required in significantly fewer patients for the Macintosh group (11.1%) than for the McGrath (48.6%) and Pentax (51.4%) groups. Thus, compared to the McGrath video laryngoscope and Pentax Airway Scope, the Macintosh laryngoscope allowed shorter nasotracheal intubation times and better facilitated tracheal navigation, requiring less use of the cuff inflation method to navigate the tracheal tube into the glottic inlet.

Project description:BackgroundPatients undergoing oral and maxillofacial surgeries under general anesthesia usually require nasotracheal intubation. When presented with patients with equally patent nostrils, selection of the nostril to use for intubation is an important decision for facilitating intubation. The objective of this trial is to determine whether choice of nostril impacts nasotracheal intubation when using a video rigid stylet in patients undergoing oral and maxillofacial surgery.MethodsFifty patients scheduled for elective oral and maxillofacial surgery requiring nasotracheal intubation were randomly allocated into two groups to undergo nasotracheal intubation through the left nostril (Group L, n = 25) or the right nostril (Group R, n = 25). Intubation was performed by experienced anesthesiologists using a video rigid stylet. The primary endpoint was time to successful intubation, which was defined as the duration from when the tip of the stylet-tube assembly entered the selected nostril to when the tube entered the trachea. Secondary outcomes included: length of time for device insertion; length of time for tube insertion; total success rate; first-attempt success rate; number of intubation attempts; requirement of airway assisted maneuvers; incidence and severity of epistaxis. Intubation-related adverse events were monitored for up to postoperative 24 h.ResultsMedian time (interquartile range) to tracheal intubation was 25.3 seconds (20.7 to 27.6) in Group L and 26.8 seconds (22.5 to 30.0) in Group R (median difference (MD) = 1.9; 95% confidence interval (CI) -1.8 to 5.7, P = 0.248). Nasotracheal intubation was successful in all patients in both groups and the first-attempt success rates in both groups were similar (Group L: 96% (24/25); Group R: 96% (24/25); relative risk (RR) 1.0; 95% CI 0.9 to 1.1; P > 0.999). No significant difference of requirement of assisted maneuvers was noted between the two groups (Group L: 36% (9/25); Group R: 28% (7/25); RR 0.8; 95% CI 0.3-1.8; P = 0.544). Furthermore, all patients showed a high quality of visualization of the glottis (Cormack and Lehane Grade I). For safety outcomes, the incidence and severity of epistaxis during intubation was comparable between the two groups. There were no significant differences between the selection of nostrils and intubation-related adverse events up to 24 h after surgery.ConclusionsWhen considering which nostril to use for intubation with video rigid stylet, either nostril can be used similarly.Trial registrationClinicaltrials.gov .

Project description:PurposeVideolaryngoscopy in nasotracheal intubation has been reported to be better than direct laryngoscopy. The most suitable type of videolaryngoscope remains unknown. This study aimed to compare two videolaryngoscopes (McGrath MAC and Pentax AWS) with a Macintosh laryngoscope during nasotracheal intubation.MethodsOverall, 123 patients older than 18 with normal airways who needed nasotracheal intubation were randomly allocated into three groups: Macintosh (n=41), McGrath (n=41), and Pentax (n=41). Intubation time was the primary outcome and subdivided into three steps: nose to oropharynx, oropharynx to laryngeal inlet, and laryngeal inlet to trachea. Time required, ease of each step, glottic view grade, modified nasal intubation-difficulty score, and subjective difficulty were evaluated.ResultsIntubation time among the three groups was not significantly different (Macintosh 34.6±8.1 seconds, McGrath 35.2±7.9 seconds, Pentax 36.2±9.7 seconds; p=0.727). While the glottal view was better with videolaryngoscopes (I/IIa/IIb/III 36.6%/36.6%/19.5%/7.3% vs 82.9%/9.8%/7.3%/0%, vs 63.4%/29.3%/4.9%/2.4%, p=0.000), modified nasal intubation-difficulty score and subjective difficulty and ease of each step were not significantly different. However, the Pentax took longest for the second step (11.8±6.3 vs 10.3±3.5 vs 15.1±7.6 seconds, p=0.001) but was shortest for the third step (2.9±2.6 vs 4.4±5.6 vs 1.7±0.7 seconds, p=0.001).ConclusionThe McGrath MAC and Pentax AWS showed no benefits in intubation time or difficulty, despite better glottal views, compared to the Macintosh laryngoscope in nasotracheal intubation. Additionally, videolaryngoscopes had variable performance at different steps of nasotracheal intubation.

Project description:Background: The data on long-term nasotracheal intubation among mechanically ventilated critically ill children is limited. The purpose of this study was to compare the rate of post-extubation airway obstruction (PEAO) with nasotracheal and orotracheal intubation. Methods: This open-label randomized controlled trial was conducted in PICU of a tertiary care and teaching hospital in North India from January-December 2020 involving intubated children aged 3 months-12 years. After written informed consent, children were randomized into nasotracheal and orotracheal intubation groups. Post-extubation, modified Westley's croup score (mWCS) was used at 10-timepoints (0-min, 30 min, 1, 2, 3, 6, 12, 24, 36, and 48-h after extubation) to monitor for PEAO. The primary outcome was the rate of PEAO; and secondary outcomes were time taken for intubation, number of intubation attempts, complications during intubation, unplanned extubation, repeated intubations, tube malposition/displacement, endotracheal tube blockade, ventilator associated pneumonia, skin trauma, extubation failure/re-intubation, duration of PICU stay, and mortality. Results: Seventy children were randomized into nasotracheal (n = 30) and orotracheal (n = 40) groups. Both the groups were similar in baseline characteristics. The rate of PEAO was similar between nasotracheal and orotracheal groups (10 vs. 20%, p = 0.14). The maximum mWCS and mWCS at 10-timepoints were similar in two groups. The time taken for intubation was significantly longer (85 vs. 48 s, p < 0.001) in nasotracheal group, whereas other secondary outcomes were similar in two groups. Conclusion: The rate of PEAO was not different between nasotracheal and orotracheal groups. Clinical Trial Registration:http://ctri.nic.in, Identifier: CTRI/2020/01/022988.
