Kumar Sinasamy T, Nazaruddin Wan Hassan WM, Hardy Mohamad Zaini R, Seevaunnamtum P, Ab Mukmin L

Anaesthesiol Intensive Ther, 2020;52(5):383-388.
PMID: 33327696 DOI: 10.5114/ait.2020.101407

INTRODUCTION: The Baska mask and i-gel are two new types of second-generation supraglottic airway devices. The aim of this study was to compare these two devices in terms of quality of insertion, quality of ventilation and post-insertion complications.
MATERIAL AND METHODS: A total of 80 adult patients who were scheduled for elective surgery under general anaesthesia were randomised to two groups: Group BM: Baska mask (n = 40) and Group IG: i-gel (n = 40). The assessment focused on ease of insertion, number of attempts, insertion time, number of corrective manoeuvres, oropharyngeal leak pressure, tidal volume, peak airway pressure (PAP) and post-insertion complications.
RESULTS: Group IG showed a significantly shorter median insertion time (13.3 [interquartile range, IQR 7.8] vs. 17.0 [IQR 9.6] s; P < 0.001), a higher percentage in the 'very easy' ease of insertion category (62.5% vs. 10.0%; P < 0.001), a higher percentage in the no corrective manoeuvre category (92.5% vs. 72.5%; P = 0.003) and a higher percentage in the no post-operative throat pain category (67.5% vs. 32.5%; P = 0.011) than Group BM. However, Group BM showed a significantly higher generated PAP than Group IG (12.7 [1.8] and 11.5 [2.2] cm H2O, respectively; P = 0.010). There were no significant differences in other parameters.
CONCLUSIONS: The i-gel was better than the Baska mask in terms of ease of insertion, speed of insertion, fewer corrective manoeuvres and less post-operative throat pain. However, the Baska mask had a better cuff seal, as shown by a higher generated PAP.

Fulltext Silicone Y-stent insertion under extracorporeal membrane oxygenation (ECMO) in a patient with tracheal tear

Mohd Esa NY, Faisal M, Vengadesa Pilla S, Abdul Rahaman JA

BMJ Case Rep, 2020 Dec 22;13(12).
PMID: 33370965 DOI: 10.1136/bcr-2020-236414

Tracheal tear after endotracheal intubation is extremely rare. The role of silicone Y-stent in the management of tracheal injury has been documented in the previous studies. However, none of the studies have mentioned the deployment of silicone Y-stent via rigid bronchoscope with the patient solely supported by extracorporeal membrane oxygenation (ECMO) without general anaesthesia delivered via the side port of the rigid bronchoscope. We report a patient who had a tracheal tear due to endotracheal tube migration following a routine video-assisted thoracoscopic surgery sympathectomy, which was successfully managed with silicone Y-stent insertion. Procedure was done while she was undergoing ECMO; hence, no ventilator connection to the side port of the rigid scope was required. This was our first experience in performing Y-stent insertion fully under ECMO, and the patient had a successful recovery.

Fulltext The Use of Stents in Children with Nasolacrimal Duct Obstruction Requiring Surgical Intervention: A Systematic Review

Tai ELM, Kueh YC, Abdullah B

Int J Environ Res Public Health, 2020 02 07;17(3).
PMID: 32046207 DOI: 10.3390/ijerph17031067

Nasolacrimal duct obstruction (NLDO) is the most common cause of childhood epiphora. It is managed conservatively in the first year of life, after which surgical treatment is classically based on a stepwise paradigm of probing, intubation, and dacryocystorhinostomy. This systematic review aims to present the current role of intubation in the management of children with NLDO requiring surgical intervention. A search for English-language articles from the electronic databases PubMed, SCOPUS, and the COCHRANE library was conducted over a period of five months in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and the Cochrane Handbook. The following keywords were used to aid retrieval: stents, children, lacrimal intubation, endoscopic dacryocystorhinostomy, external dacryocystorhinostomy, NLDO, dacryocystitis, congenital, acquired. The primary outcome was defined as the success of the intervention, determined by resolution of symptoms and patency of the lacrimal anatomy confirmed by the fluorescein dye disappearance test or syringing. Secondary outcomes included the presence of complications. A total of 144 articles were identified; of these, 35 fulfilled the study criteria. The majority of the included studies involved lacrimal intubation alone, followed by intubation as an adjunctive procedure to balloon dacryoplasty and dacryocystorhinostomy. The overall success rate of these procedures ranged from 41.1% to 100%. Post-operative complications were reported in 65.7% of the included studies. Lacrimal intubation was most commonly performed as a primary procedure in children with NLDO, with high success rates. The main complication was stent dislodgement. There is lack of evidence regarding the benefit of intubation over probing as primary treatment of congenital NLDO. In the absence of high-quality evidence, the decision of whether to perform lacrimal intubation in children with NLDO requiring surgical intervention depends on clinical judgement and other low-level evidence, such as observational non-randomised trials.

Fulltext Case report: Unusual cause of difficulty in intubation and ventilation with asthmatic-like presentation of Endobronchial Tuberculosis

Seevaunnamtum SP, Mohd Ariff Ghazali NA, Nazaruddin WM, Besari AM, Fariza NHN, Omar SC, et al.

Respir Med Case Rep, 2017;22:292-294.
PMID: 29159029 DOI: 10.1016/j.rmcr.2017.10.011

Endobronchial Tuberculosis is hazardous in causing circumferential narrowing of tracheobronchial tree despite the eradication of tubercle bacilli in the initial insult from Pulmonary Tuberculosis. They may present as treatment resistant bronchial asthma and pose challenge to airway management in the acute setting. We present a 25 year-old lady who was newly diagnosed bronchial asthma with a past history of Pulmonary Tuberculosis that had completed treatment. She presented with sudden onset of difficulty breathing associated with noisy breathing for 3 days and hoarseness of voice for 6 months. Due to resistant bronchospasm, attempts were made to secure the airway which led to unanticipated difficult intubation and ventilation. Subsequent investigations confirmed the diagnosis of Endobronchial Tuberculosis and patient was managed successfully with anti TB medication, corticosteroids and multiple sessions of tracheal dilatation for tracheal stenosis. This case highlights the unusual cause of difficulty in intubation and ventilation due to Endobronchial Tuberculosis, which required medical and surgical intervention to improve the condition.

Goh BS, Roopesh S, Marina MB, Abdullah SM

Med J Malaysia, 2014 Feb;69(1):13-5.
PMID: 24814622

This is a retrospective study examining the outcome of paediatric patients with subglottic stenosis who underwent partial cricotracheal resection (PCTR) as a primary open procedure from 2004 to 2012. There were 5 patients identified aged from 3 to 18 years old. All the subglottic stenosis were acquired type. All of them were secondary to prolonged intubation. Three patients were classified as Myer-Cotton grade III and the other two were Myer-Cotton grade IV. Two of the patients had concomitant bilateral vocal cord immobility. All patients underwent two staged PCTR . All patients underwent two staged PCTR, and one patient underwent posterior cordectomy apart from partial CTR at different setting. All patients were successfully decannulated at various durations postoperatively. Although this is an early experience in our institution, PCTR has shown to be effective and safe procedure in patients with subglottic stenosis especially those with Myer-Cotton grade III and IV.

Usage of airway ultrasound as an assessment and prediction tool of a difficult airway management

Adi O, Fong CP, Sum KM, Ahmad AH

Am J Emerg Med, 2021 04;42:263.e1-263.e4.
PMID: 32994082 DOI: 10.1016/j.ajem.2020.09.011

Airway assessment is important in emergency airway management. A difficult airway can lead to life-threatening complications. A perfect airway assessment tool does not exist and unanticipated difficulty will remain unforeseen. Current bedside clinical predictors of the difficult airway are unreliable but airway ultrasound can be used as an adjunct to predict difficult laryngoscopy. We report a case of a 60-year-old man presenting to the emergency department with shortness of breath, hoarseness of voice and stridor. Airway ultrasound revealed a large laryngeal mass narrowing the upper airway, extending to bilateral vocal cords with heterogenous echogenicity. In view of impending complete upper airway obstruction, acute respiratory distress and airway ultrasound findings, urgent emergency tracheostomy was chosen as definitive airway over endotracheal intubation or surgical cricothyroidotomy. Point of care ultrasound (POCUS) was used to evaluate this patient with severe upper airway obstruction. A laryngeal mass was detected by ultrasound and this pointed towards the presence of a difficult airway. POCUS was a good non-invasive tool used for airway assessment in this uncooperative and unstable patient. Ultrasound predictors of the difficult airway include the inability to visualize the hyoid bone, short hyomental distance ratio, high pretracheal anterior neck thickness and large tongue size. Besides airway assessment, ultrasound can also help to predict endotracheal tube size, confirm intubation and guide emergency airway procedures such as cricothyroidotomy and tracheostomy. Point of care ultrasound of the upper airway can be used in airway assessment to identify distorted airway anatomy, pathological lesions and guide treatment decisions.

Fulltext Comparison of two bolus doses of esmolol for attenuation of haemodynamic response to tracheal intubation

Sharma S, Ghani AA, Win N, Ahmad M

Med J Malaysia, 1995 Dec;50(4):372-6.
PMID: 8668059

This prospective study was designed to compare the effectiveness of esmolol (either 100 mg or 200 mg) with a placebo in blunting the haemodynamic response to laryngoscopy and intubation. Seventy-five patients of ASA I or II scheduled for routine-surgery were selected and entered into a placebo-controlled study. Patients were randomly allocated to receive placebo, 100 mg or 200 mg of esmolol IV as part of an anaesthetic induction technique. There were no significant differences in the demographic distribution of the patients in the study. There was no statistical difference in the baseline heart rate (HR) and systolic blood pressure (SBP) between the three groups. One minute after the administration of the drug (prior to intubation) the differences in HR between the placebo group and both the 100 mg and 200 mg groups were significant (p < 0.05), and also at 1 min and 2 min following intubation for the 200 mg group (p < 0.05). In the 200 mg group there was a significant decrease, compared with placebo, in SBP at 1 min (p < 0.05) and at 2 min (p < 0.05) after intubation. In this study, adequate haemodynamic control following was obtained with the administration of 200 mg of esmolol.

Post-thyroidectomy sore throat following endotracheal intubation

Hisham AN, Roshilla H, Amri N, Aina EN

ANZ J Surg, 2001 Nov;71(11):669-71.
PMID: 11736830 DOI: 10.1046/j.1445-1433.2001.02230.x

Background: Sore throat is not an uncommon complaint following general anaesthesia (GA) with endotracheal intubation. It has been a source of considerable discomfort particularly in those patients who had thyroid surgery. Driven by the increased number of patients with post-intubation sore throat following thyroid surgery, the aim of the present study was to evaluate the contributing factors of sore throat in patients who had thyroid surgery under general anaesthesia.
Methods: A total of 57 consecutive patients who had thyroid surgery from November 1998 to April 1999 was included in this prospective study. Factors such as intubation time, number of intubation attempts, size and type of endotracheal tube (ETT) used, gender and age were recorded. The nature and extent of the surgical procedures were also studied. Postoperative symptoms were assessed by questionnaire on the day after surgery and the different parameters were compared and analysed.
Results: The incidence of post-intubation sore throat following thyroid surgery was documented in 39 (68.4%) patients. Twenty-seven (47.4%) patients had a mild complaint of sore throat, which resolved after the third day. The data from the present study show that the size of ETT and extent of surgical procedure were significant contributing factors affecting the postoperative recovery.
Conclusion: The outcome of the present study demonstrated a substantial increased incidence of sore throat after thyroid surgery under GA. Postoperative sore throat following thyroid surgery under GA may be caused by multiple contributing factors. Nonetheless effort and care should be taken during endotracheal intubation and surgery to reduce this unpleasant complaint arising mainly from pharyngeal irritation or trauma.

Fulltext Smoker Desaturation during General Anaesthesia: A Case Report

Hadi, M.A., Azrina, M.R., Zamzila, A., Ariff, O.

International Medical Journal Malaysia, 2009;8(1):57-59.
MyJurnal

We report a case of sudden hypoxaemia after intubation in a patient who had smoked a few hours prior to a surgical procedure. The cause of his desaturation was not related to bronchial secretions, bronchospasm or obstruction of the upper airways but most likely due to reduced oxygen saturation in the body prior to surgery. We managed to secure the airway and prevent prolonged desaturation by instituting remedial measures. Our conclusion is that cessation of smoking is very important and need to be emphasized in all patients having surgery under general anaesthesia. This applies to emergency cases as well.

Fulltext LeHeR, a simple novel approach for difficult airway in non-trauma patients

Yezid NH, Poh K, Md Noor J, Arshad A

BMJ Case Rep, 2019 Aug 10;12(8).
PMID: 31401573 DOI: 10.1136/bcr-2019-230201

Managing the difficult airway presents a great challenge to anaesthesiologists and emergency physicians. Although there are many methods and scoring systems available to predict and anticipate difficult airway, the dictum in emergency airway is to always expect the unexpected. We have encountered a novel simple method of improving laryngoscopic view in difficult airway. We report four cases of difficult airway encountered in our district hospital from November 2017 to December 2018, in which intubation was performed using a simple manoeuvre called supine left head rotation (LeHeR). In all these cases, LeHeR manoeuvre has proven to be successful after more than a single attempt at intubation using various methods. The manoeuvre improves drastically the laryngoscopic view of Cormack-Lehane from 3B and 4 to 1 and 2.

PMID: 22589656 MyJurnal

Theophylline toxicity is a life-threatening toxidrome that can present to an emergency department. To ascertain an immediate provisional diagnosis in toxicology at the emergency department is very challenging, especially when the patient presents with altered mental status, because the clinical features of several toxidromes overlap. We report a case of survival of undiagnosed theophylline toxicity that required intubation for two days in the intensive care unit. This was the first case to have been reported from our department. Accurate diagnosis of a toxidrome by gaining adequate history and conducting a thorough physical examination and early serum toxicology screening, coupled with good knowledge of toxicology, will lead to better patient outcomes.

The efficacy of a subhypnotic dose of propofol in preventing laryngospasm following tonsillectomy and adenoidectomy in children

Batra YK, Ivanova M, Ali SS, Shamsah M, Al Qattan AR, Belani KG

Paediatr Anaesth, 2005 Dec;15(12):1094-7.
PMID: 16324030 DOI: 10.1111/j.1460-9592.2005.01633.x

BACKGROUND: Laryngospasm is a well-known problem typically occurring immediately following tracheal extubation. Propofol is known to inhibit airway reflexes. In this study, we sought to assess whether the empiric use of a subhypnotic dose of propofol prior to emergence will decrease the occurrence of laryngospasm following extubation in children.
METHODS: After approval from the Institutional Ethics Committee and informed parental consent, we enrolled 120 children ASA physical status I and II, aged 3-14 years who were scheduled to undergo elective tonsillectomy with or without adenoidectomy under standard general anesthesia. Before extubation, the patients were randomized and received in a blinded fashion either propofol 0.5 mg.kg(-1) or saline (control) intravenously. Tracheal extubation was performed 60 s after administration of study drug, when the child was breathing regularly and reacting to the tracheal tube.
RESULTS: Laryngospasm was seen in 20% (n = 12) of the 60 children in the control group and in only 6.6% (n = 4) of 60 children in the propofol group (P < 0.05).
CONCLUSIONS: During emergence from inhalational anesthesia, propofol in a subhypnotic dose (0.5 mg.kg(-1)) decreases the likelihood of laryngospasm upon tracheal extubation in children undergoing tonsillectomy with or without adenoidectomy.

PMID: 25500849 MyJurnal

Tracheal agenesis is a rare congenital airway anomaly which presents as an airway emergency at birth. We report a case of late premature Chinese infant with tracheal agenesis type II (by Floyd's classification) who presented with severe respiratory distress at birth. He had multiple failed attempts at intubations with accidental oesophageal intubation and ventilation. Tracheal agenesis with tracheo-oesophageal fistula was suspected from an emergency optical laryngoesophagoscopy done. The infant was subsequently stabilized on oesophageal ventilation. The diagnosis was confirmed on CT scan and parents were counseled regarding the poor outcome and decided for withdrawal at day 7 of life.

Partial vs full glottic view with CMACTM D blade intubation of airway with simulated cervical spine injury: a randomized controlled trial

Cheong CC, Ong SY, Lim SM, Wan A WZ, Mansor M, Chaw SH

Expert Rev Med Devices, 2023 Feb;20(2):151-160.
PMID: 36715659 DOI: 10.1080/17434440.2023.2174850

PURPOSE: A previous study reported a shorter time to tracheal intubation by reducing percentage of glottic opening (POGO) view to <50% when intubating a normal adult airway using the GlidescopeTM blade. We evaluate the efficacy of reducing POGO to <50% when intubating patients with rigid cervical immobilization using CMACTM D blade.
METHODS: One hundred and four adult patients were randomized to group POGO 100% or POGO <50% . Laryngoscopy was performed by advancing tip of the D blade at vallecula. POGO 100% was achieved by exerting upward force to displace epiglottis until glottic opening from the anterior commissure to inter arytenoid notch. POGO < 50% was acquired by withdrawing the D blade tip dorsally from vallecula. The primary outcome was time to intubation.
RESULTS: The median time (IQR) to successful intubation was 29 (25-35) seconds for group POGO < 50% and 34 (28-40) seconds for group with POGO 100% (difference in medians, 5 seconds; 95% confidence interval, 2 to 8, p = 0.003). Complications were minor.
CONCLUSION: Using the CMACTM D blade with a reduced POGO in patients with cervical spine immobilization resulted in faster tracheal intubation.
TRIAL REGISTRATION: The trial is registered at ClinicalTrial.gov (CT.gov identifier: NCT04833166).

Fulltext Tracheal agenesis: a rare cause of unsuccessful tracheal intubation during resuscitation

Iszuari M, Mazita A, Tan GC, Hayati AR, Shareena I, Cheah FC

Med J Malaysia, 2010 Dec;65(4):317-8.
PMID: 21901957

Tracheal agenesis is a rare congenital airway anomaly that usually results in a fatal outcome. The diagnosis is usually made through post-mortem examination. In the current literature, there has been no reported long-term survival although a few reports claimed prolongation of life of several hours to days. This condition is commonly associated with premature birth, polyhydramnios and a male predominance. In 90% of the cases, it is associated with multiple cardiovascular, gastrointestinal and genitourinary tract anomalies which are incompatible with life. We report a case of a premature newborn with severe respiratory distress, absent cry and cyanosis soon after birth. Attempts at endotracheal intubation failed as it was no possible to negotiate the tube beyond the vocal cords. Needle cricothyrotomy and attempted tracheostomy also failed to secure the airway. The diagnosis was confirmed at post-mortem examination.

Fulltext COVID-19 aerosol box as protection from droplet and aerosol contaminations in healthcare workers performing airway intubation: a randomised cross-over simulation study

Noor Azhar M, Bustam A, Poh K, Ahmad Zahedi AZ, Mohd Nazri MZA, Azizah Ariffin MA, et al.

Emerg Med J, 2021 Feb;38(2):111-117.
PMID: 33219133 DOI: 10.1136/emermed-2020-210514

BACKGROUND: Concerns over high transmission risk of SARS-CoV-2 have led to innovation and usage of an aerosol box to protect healthcare workers during airway intubation in patients with COVID-19. Its efficacy as a barrier protection in addition to the use of a standard personal protective equipment (PPE) is not fully known. We performed a simulated study to investigate the relationship between aerosol box usage during intubation and contaminations on healthcare workers pre-doffing and post-doffing of PPE.
METHODS: This was a randomised cross-over study conducted between 9 April to 5 May 2020 in the ED of University Malaya Medical Centre. Postgraduate Emergency Medicine trainees performed video laryngoscope-assisted intubation on an airway manikin with and without an aerosol box in a random order. Contamination was simulated by nebulised Glo Germ. Primary outcome was number of contaminated front and back body regions pre-doffing and post-doffing of PPE of the intubator and assistant. Secondary outcomes were intubation time, Cormack-Lehane score, number of intubation attempts and participants' feedback.
RESULTS: Thirty-six trainees completed the study interventions. The number of contaminated front and back body regions pre-doffing of PPE was significantly higher without the aerosol box (all p values<0.001). However, there was no significant difference in the number of contaminations post-doffing of PPE between using and not using the aerosol box, with a median contamination of zero. Intubation time was longer with the aerosol box (42.5 s vs 35.5 s, p<0.001). Cormack-Lehane scores were similar with and without the aerosol box. First-pass intubation success rate was 94.4% and 100% with and without the aerosol box, respectively. More participants reported reduced mobility and visibility when intubating with the aerosol box.
CONCLUSIONS: An aerosol box may significantly reduce exposure to contaminations but with increased intubation time and reduced operator's mobility and visibility. Furthermore, the difference in degree of contamination between using and not using an aerosol box could be offset by proper doffing of PPE.

Giant haemangioma of the tongue is a disease which can
obstruct the oropharyngeal airway and is presented with
obstructive symptoms. Due to its vascularity, inserting
laryngoscope for intubation can cause high risks, such as
inducing bleeding. Hypoxia and excessive bleeding must be
anticipated while securing the airway. We present a case of
novel usage of dexmedetomidine as a conscious sedation agent
for awake fibre optic intubation in a 9-year-old child with
obstructive symptoms secondary to a huge tongue
haemangioma, who was presented for interventional
sclerotherapy of the lesion.
