OBJECTIVES: Positioning during endotracheal intubation (ETI) is critical to ensure its success. We aimed to determine if the ramping position improved laryngeal exposure and first attempt success at intubation when compared to the sniffing position.

METHODS: PubMed, EMBASE, and Cochrane CENTRAL databases were searched systematically from inception until January 2020. Our primary outcomes included laryngeal exposure as measured by Cormack-Lehane Grade 1 or 2 (CLG 1/2), CLG 3 or 4 (CLG 3/4), and first attempt success at intubation. Secondary outcomes were intubation time, use of airway adjuncts, ancillary maneuvers and complications during ETI.

RESULTS: Seven studies met our inclusion criteria, of which 4 were RCTs and 3 were cohort studies. The meta-analysis was conducted by pooling the effect estimates for all 4 included RCTs (n=632). There were no differences found between ramping and sniffing positions for odds of CLG 1/2, CLG 3/4, first attempt success at intubation, intubation time, use of ancillary airway maneuvers and use of airway adjuncts, with evidence of high heterogeneity across studies. However, the ramping position in surgical patients is associated with increased likelihood of CLG 1/2 (OR=2.05, 95% CI 1.26 to 3.32, p=0.004) and lower likelihood of CLG 3/4 (OR=0.49, 95% CI 0.30 to 0.79, p=0.004), moderate quality of evidence.

CONCLUSION: Our meta-analysis demonstrated that the ramping position may benefit surgical patients undergoing ETI by improving laryngeal exposure. Large-scale well-designed multicentre RCTs should be carried out to further elucidate the benefits of the ramping position in the surgical and intensive care unit patients.

Orbital cellulits is one of the life threatening event that should not be missed out and must be distinguished from preseptal cellulitis. It is an infective process involving ocular adnexal structures posterior to the orbital septum. High index of suspicion is the key to its diagnosis as even experienced physician can miss. Here, we present a case of a 15-year-old female who presented with progressive swelling over right forehead associated with high grade fever, headache and purulent discharge of the swelling. She was diagnosed with sepsis due to right forehead abscess and was treated with intravenous antibiotics followed with admission. However, she suddenly deteriorated in the ward which required intubation and thereby Intensive Care Unit (ICU) admission. Investigations revealed fluid collection at right retrobulbar space suggestive of an abscess where emergency drainage was carried out. Unfortunately, her condition worsened and patient succumbed at day-10 of admission, despite all efforts.

Journal of Surgical Academia, 2013;3(2):92-96.

MyJurnal

We here describe a videolaryngoscope assisted fibreoptic tracheal intubation in a 17-year-old patient with Hunter Syndrome (Mucopolysaccharidosis Type II) and known difficult intubation who required posterior cervical fusion surgery for cervical canal stenosis. The patient had a history of failed nasal and oral fibreoptic intubation. The use of a videolaryngoscope enabled continuous visualization of the tracheal inlet and allowed a straightforward nasal fibreoptic intubation attempt without complications. This report suggests a viable alternative for the management of a known difficult airway in children with mucopolysaccharidosis.

Choanal stenosis has recently been recognized as a late complication of radiation therapy for nasopharyngeal carcinoma. The management of velopharyngeal stenosis is challenging with high risk of restenosis. We report a case of velopharyngeal stenosis post-radiotherapy and illustrated the use of mitomycin-C to prevent restenosis. Mitomycin-C application has being shown useful adjunct to surgical technique in managing nasopharyngeal stenosis for surgeons.

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

Adi O, Fong CP, Sum KM, Ahmad AH

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.

MyJurnal

Urethral catheterisation is a common and safe procedure performed routinely. The small size of the urethra in a child necessitates the use of an infant feeding tube (Size 5 to 8 F) for catheterisation. Knotting within the bladder is a rare complication with significant morbidity often necessitating surgical or endoscopic removal. Insertion of an excessive length of tube contributes to coiling and knotting. We report an instance of knotting of an infant feeding tube in the proximal penile urethra of a 4 year-old male child requiring urethrotomy to remove it. Awareness of the risk and proper technique can reduce this complication.

Introduction: Bronchoscopy is a commonly used procedure in the context of aspiration in the Intensive Care Unit setting. Despite its ability to remove mucus plug and undigested gastric contents, aspiration of gastric content into the trachea is one of the most feared complications among anesthesiologist.

Discussion: The scenario is made worst if the aspiration causes acute hypoxemic respiratory failure immediately post intubation. However, in the event of desaturation, the quick decision to proceed with bronchoscopy is a challenging task to the anesthesiologist without knowing the causes.

Case presentation: We present a case of a 12-year-old boy who had a difficult-to-ventilate scenario post transferring and immediately connected to ventilator in operation theatre (OT) from portable ventilator from the emergency department. She was successfully managed by bronchoscopy.

Conclusion: Special attention should be given to the difficult-to-ventilate scenario post intubation of traumatic brain injury patient prior to operation. Prompt diagnosis and bronchoscope-assisted removal of foreign body was found to be a successful to reduce morbidity and mortality.

Transnasal endoscopic placement of nasoenteric feeding tubes: outcomes and limitations in non-critically ill patients

Mahadeva S, Malik A, Hilmi I, Qua CS, Wong CH, Goh KL

Nutr Clin Pract, 2008 Apr-May;23(2):176-81.

Transnasal endoscopic placement of nasoenteric tubes (NETs) has been demonstrated to be useful in the critical care setting, with limited data on its role in non-critically ill patients. The authors collected data on consecutive patients from a non-critical care setting undergoing transnasal endoscopic NET placement. All NETs were endoscopically placed using a standard over-the-guidewire technique, and positions were confirmed with fluoroscopy. Patients were monitored until the removal of NETs or death. Twenty-two patients (median age = 62.5 years, 36.4% female) were referred for postpyloric feeding, with main indications of persistent gastrocutaneous fistula (n = 6), gastroparesis or gastric outlet obstruction (n = 5), duodenal stenosis (n = 6), acute pancreatitis (n = 4), and gastroesophageal reflux after surgery (n = 1). Postpyloric placement of NET was achieved in 19 of 22 (86.3%) patients, with 36.8% tube positions in the jejunum, 47.4% in the distal duodenum, and 15.8% in the second part of the duodenum. NET placement was least successful in cases with duodenal stenosis. NETs remained in situ for a median of 24 days (range, 2-94), with tube dislodgement (n = 3) and clogging (n = 5) as the main complications. NET feeding resulted in complete healing of gastrocutaneous fistulae in 5 of 6 patients and provision of total enteral nutrition in 3 of 4 cases of acute pancreatitis and 9 of 11 cases of gastroparesis or proximal duodenal obstruction. Transnasal endoscopy has a role in the placement of NET in non-critically ill patients requiring postpyloric feeding. However, there are some limitations, particularly in cases with altered duodenal anatomy.

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.

Mucormycosis is a rare fungal infection and high mortality that commonly affects patients with the weakened immune system. We present an unusual case of tongue necrosis probably due to the healthcare-associated mucormycosis (HCM) in a diabetic patient. Although cannot be proved with certainty, we surmise that intubation as a risk factor in our case. The diagnosis was confirmed by histopathological examination (HPE) of the necrotic tissue specimen. The patient was responded well to lipid complex amphotericin B (250mg) regime after surgery. Subsequent follow up revealed that no signs of recurrence. Early, recognition, diagnosis, prompt treatment and awareness among clinician are representing the most effective way of managing the disease.

Submental intubation has been used as an alternative to conventional intubation in the field of oral and maxillofacial surgery since its introduction by Francisco Hernández Altemir in 1986. A review of submental intubation was performed using data from all case reports, case-series, and prospective and retrospective studies published between 1986 and 2016. The indications, variations in incision length, incision sites, types of endotracheal tube used, methods of exteriorization, and complications were recorded and analyzed. A total of 70 articles reporting 1021 patients were included. The main indication was maxillofacial trauma (86.9%, n=887), followed by orthognathic surgery (5.8%, n=59), skull base surgery (2.8%, n=29), and rhinoplasty and rhytidectomy (1.5%, n=15). The complication rate was relatively low: 91.0% of patients (n=929) were complication-free. The most common complication was infection, occurring in 3.5% (n=36) of the total number of patients, followed by scarring (1.2%, n=12) and formation of an orocutaneous or salivary fistula (1.1%, n=11). In summary, submental intubation is a good alternative airway with minimal complications.

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.
