Possible complications of nasotracheal intubation include injury to the nasal or pharyngeal mucosa. Dissection of the retropharyngeal tissue by the endotracheal tube is one of the rarer of the more severe complications. Previous studies have indicated that the Parker Flex-Tip (PFT) tracheal tube (Parker Medical, Highlands Ranch, Colo) reduces the incidence of mucosal injury. We experienced a case involving inadvertent retropharyngeal placement of a PFT tube in a 29-year-old patient during nasotracheal intubation under general anesthesia for elective dental treatment. Despite thermosoftening the PFT tube, expanding the nasal meatus, and ensuring gentle maneuvering, the tube intruded into the left retropharyngeal mucosa. However, the injury was not severe, and the only required treatment was the administration of antibiotics and corticosteroids. Even when a PFT tube is utilized, pharyngeal dissection is possible. When resistance is felt during passing of the PFT tube through the nasopharynx, an alternative method to overcome this resistance should be utilized.

Mandibular Third Molars

A 23-year-old healthy man was scheduled for extraction of his mandibular third molars under general anesthesia with nasotracheal intubation. Sudden sinus tachycardia up to 170 beats/min occurred when applying an epinephrine solution-soaked swab into the nasal cavity for preventing epistaxis during intubation. This was presumably evoked by submucosal migration of the swab into a false passage created because of the force applied during a prior failed attempt at nasal passage of the tracheal tube, and rapid epinephrine absorption by the traumatized mucosa. The causes of the unexpected severe tachycardia in our patient are discussed.

Autosomal Dominant Disorder

Abstract Noonan syndrome (NS) is an autosomal dominant disorder characterized by facial anomalies, short stature, chest deformity, congenital heart diseases, and other comorbidities. The challenges faced during anesthetic management of patients with NS could be due to congenital heart diseases, hemostatic disorders, and airway anomalies. Here we describe dental treatment under general anesthesia performed for a 28-year-old man with NS. He had characteristic features of NS along with mild pulmonary valve stenosis. Dental treatment under general anesthesia was performed successfully on 13 occasions with nasotracheal intubation under curve-tipped suction catheter guidance or insertion of a reinforced laryngeal mask airway. This case suggests that for patients with NS, who might present several challenges, dental anesthesiologists should consider the extent of the patient's disorders to enable them to perform dental treatment safely under general anesthesia.

The purpose of this article was to determine if pediatric dental treatment under general anesthesia utilizing orotracheal intubation takes longer than using nasotracheal intubation techniques. Twenty-six American Society of Anesthesiologists Physical Status Classification I and II pediatric dental patients, ages 2–8 years treated under general anesthesia, were assigned to 1 of 2 groups: (a) nasotracheal intubation (control, n = 13), (b) orotracheal intubation (experimental, n = 13). Times for intubation, radiographic imaging, and dental procedures, as well as total case time were quantified. Data were collected on airway difficulty, numbers of providers needed for intubation, intubation attempts, and intubation trauma. There was a significant difference in mean intubation time (oral = 2.1 minutes versus nasal = 6.3 minutes; p < .01). There was no difference in mean radiograph time (oral = 4.2 minutes versus nasal = 3.4 minutes; p = .144), and overall radiograph image quality was not affected. There was no difference in dental procedure time (p = .603) or total case time (p = .695). Additional providers were needed for intubation and more attempts were required for nasotracheal intubation versus orotracheal intubation (6 additional providers/22 attempts vs 0 additional providers/15 attempts, p < .01 and p < .05, respectively). Nine of 13 nasotracheal intubations were rated as traumatic (69%) versus 0 of 13 for orotracheal intubations (0%) (p < .01). In 7/9 orotracheal intubation cases (78%), the tube was not moved during treatment (p < .01). Orotracheal intubation does not increase case time, does not interfere with radiographic imaging, and is less traumatic for the patient when performed by physician anesthesiologists, emergency and pediatric medicine physician residents, certified registered nurse anesthetists, and student nurse anesthetists, all with variable nasotracheal intubation experience.

Possible Cause

A nasogastric tube is often used along with a nasal endotracheal tube during oral surgery or dental treatment under general anesthesia. Although the insertion of a nasogastric tube is a simple procedure, it can be associated with complications that lead to potentially serious consequences. The knotting of a nasogastric tube around an endotracheal tube is rare. Here, we report a case in which the nasogastric tube became knotted around the nasal endotracheal tube in the nasopharynx. We compare this case with 4 previous similar cases and provide a theory of how the nasogastric tube might have become knotted.

The Right

Permanent sequelae of nasotracheal intubation are uncommon, but acute ulceration and squamous metaplasia occur. Histological sections from the trachea and main bronchi were examined in 12 infants. A nasotracheal tube had been inserted during the first two weeks of life of these infants and had been in place for more than one week. In four cases the patient died some time (7 to 108 days) after extubation. Similar sections from patients who were not intubated, intubated only for attempted resuscitation, or intubated for several hours were studied for comparison. The sections were classified according to the degree of mucosal loss and metaplasia, and the extent of the lesions was estimated. Squamous change was seen in most sections from all 12 patients with the exception of one who died 57 days after extubation. Some respiratory epithelium was seen in all patients. In the eight patients who died while intubated, the changes were more marked in the right main bronchus than the left in seven, and more marked in the lower trachea than the upper in five. In the two patients intubated for several hours, in addition to mucosal loss, early metaplasia was seen. It is suggested that mucosal loss is replaced by the squamous metaplasia, and that trauma caused by suction catheters in the lower trachea and right main bronchus is more extensive than that due to the endotracheal tube itself.

AbstractIntroduction:Hand held, colorimetric, end-tidal CO2 detector devices are being used to verify correct endotracheal tube (ETT) placement. The accuracy of these devices has been questioned in situations of cardiac arrest. The use of the esophageal detector device (EDD) is an easy alternative for detection of ETT placement, and may be more accurate in situations of cardiac arrest.Hypothesis:The use of the esophageal aspiration device in comparison with a colorimetric end-tidal CO2 detector is more accurate in detecting proper ETT placement and easier to use in the prehospital setting than is the colorimetric end-tidal CO2 detection device.Methods:This was a prospective alternating weeks, 6-month study in a prehospital setting. Participants included all patients older than 18 years who were intubated by the Portsmouth, Virginia Emergency Medical Services (EMS) personnel from 01 July 1993 through 31 December 1993. The aspiration device used, also known as an esophageal detector device (EDD), was a 60 ml, luer-lock syringe attached to a 15 mm ETT adapter. Its efficacy was compared with an already accepted method of ETT position detection, the colorimetric endtidal CO2 detector. Each device was used on alternating weeks, and correct ETT placement was determined by the receiving emergency department physician using standard techniques. Chi-square analysis and Fisher's Exact test were used to compare parameters, time of device use, and ease of use. Sensitivity and specificity were calculated, and provider preference was assessed using a survey instrument administered following completion of the study.Results:There were 49 patients who met the inclusion criteria, but six were excluded because of situational circumstances rendering use of the device a possible compromise of patient care. Twenty-five patients were in the EDD group, and 18 were in the endtidal CO2 detector group. There was no statistically significant difference detected between groups for the gender ratio, underlying condition, CPR in progress, perceived difficulty of intubation, or percentage of nasotracheal intubation. The EDD was significantly easier to use (p<0.005). There was no statistically significant difference in time required for use of end-tidal CO2 detector device versus the EDD. The sensitivity and specificity for correct tracheal placement using the EDD was 100%, and the sensitivity for correct tracheal placement using the end-tidal CO2 detector device was 78%. Use of the EDD was preferred over use of the end-tidal CO2 detector device by 75% of participating EMS providers. One case of nasotracheal intubation with an ETT placement above the cords raised the question of accuracy of this device in situations where direct visualization is not utilized.Conclusion:The EDD was accurate in all cases of orotracheal intubation, and was easier to use than was end-tidal CO2 detector device. It was preferred by 75% of participating EMS providers. In cases in which the ETT may be above the vocal cords, caution must be used with interpreting the results obtained by use of the EDD.

Introduction: Fibreoptic Intubation (FOI) is the gold standard for managing difcult airways. There are various approaches such as: Nebulization with lidocaine; 'Spray as you go'(SAYGO); Airway nerve block - blocking superior laryngeal nerve & recurrent laryngeal nerve & sedation. The present study aims to compare 'airway nerve block' (NB) and 'spray as you go'(SA) method for awake exible bronchoscopic intubation used in combination with conscious sedation. Methods: 60 patients of age group 18 – 65 years with difcult airway undergoing general anaesthesia with nasotracheal intubation, were randomly allocated into two groups. After premedication & nasal preparation, all patients received injection dexmedetomidine at a dose of 1µg/kg in 100ml of 0.9% NS over 10 minutes. In Group SA, 2ml lignocaine 4% was sprayed above and below the cords after visibility of glottic opening via working channel of the bronchoscope and 2 ml lignocaine 4% within trachea before insertion of endotracheal tube. In Group NB, bilateral superior laryngeal nerves & recurrent laryngeal nerve was blocked. Then a exible breoptic bronchoscope preloaded with a exometallic endotracheal tube of appropriate size was then inserted via nasal route. Results: The mean intubation time for Group NB [87.27 ± 7.58 sec] was shorter than that for Group SA [190.33 ± 9.14] (p<0.0001). Conclusion: Awake exible bronchoscopic intubation under sedation with airway nerve block provides better intubating conditions compared to SAYGO

Objective: To find the best method of intubation in patients sustaining pan-facial trauma by comparing the pros and cons of each technique. Materials and methods: Three different types of intubation techniques (nasotracheal intubation, orotracheal intubation, and sub-mental intubation) were considered in this study. The study population involves 9 patients who have undergone treatment for pan-facial trauma under general anesthesia (3 patients per technique) and the variables of clinical outcome of each group were recorded. Results: Nasal intubation is the most common and safest method of intubation. However, it can’t be used in some types of pan-facial trauma. In cases like these, oral intubation is not preferred. As it severely compromises maxillofacial repair because of interference with the placement of intermaxillary fixation [3](IMF), which is used to establish the patient s occlusion in the intraoperative period. Submental intubation is an alternative with minimal risk to tracheostomy when orotracheal or nasotracheal intubation is not appropriate. The submental intubation technique gave an uninterrupted surgical field, unobstructed airway, ease of gaining occlusion in general anesthesia, less intraoperative and postoperative complications and it overcomes the disadvantages of both nasotracheal and orotracheal intubation. Conclusion: Preferred techniques of securing an airway are orotracheal, nasotracheal intubation. However these techniques may not always be applicable, thus a trauma surgeon-anesthetist team should always have alternative techniques in their armamentarium which secures the patient's airways without interfering with occlusion, to gain at most postoperative esthetic and functional results.
