PURPOSE: Anesthesiologists can use supraglottic airway devices as a rescue technique for failed intubation even in patients with an increased risk of gastric regurgitation. In this randomized study, we aimed to evaluate the effects of cricoid pressure and paratracheal pressure on placement of the i-gel® (Intersurgical Ltd., Wokingham, Berkshire, UK). METHODS: After induction of anesthesia in 76 adult patients, we inserted the i-gel under paratracheal or cricoid pressure, and assessed the success rate of i-gel insertion, resistance during insertion, time required for insertion, accuracy of the insertion location, tidal volumes, and peak inspiratory pressure with or without each maneuver after i-gel insertion...

Anesthesia for patients with life-threatening injuries is an essential part of post-accident care. Unfortunately, there is variability in trauma anesthesia care and numerous nonstandardized methods of working with patients remain. Uncertainty exists as to when and how best to intubate trauma patients, the use of vasopressors, and the appropriate management of severe traumatic brain injury. Some physicians recommend prehospital rapid sequence intubation, whereas others use bag-mask ventilation at lower pressures with no cricoid pressure and early transport to a trauma center...

BACKGROUND: Gastric content regurgitation and aspiration are the dreaded complications of securing the airway. Cricoid pressure hinders intubation and causes lower esophageal sphincter (LES) relaxation. A recent study suggests no added benefit of cricoid pressure in preventing pulmonary aspiration of gastric contents. Metoclopramide increases LES tone, prevents gastroesophageal reflux, and increases antral contractions. Hence, we wanted to study the efficacy of metoclopramide for preventing gastric regurgitation during endotracheal intubation (ETI) in patients presenting to the emergency department (ED)...

Acquired subglottal stenosis is an unpredicted complication that can occur in some patients who have undergone prolonged endotracheal intubation. It is a narrowing of the airway at the level of the cricoid cartilage that can restrict airflow and cause breathing difficulty. Stenosis is typically treated with endoscopic airway dilation, with some patients experiencing multiple recurrences. The study highlights the potential of computational fluid dynamics as a non-invasive method for monitoring subglottic stenosis, which can aid in early diagnosis and surgical planning...

The Sellick maneuver is used for endotracheal intubation to prevent the occurrence of gastroesophageal reflux. The aim of the present study was to observe the effect of the Sellick maneuver on safety, esophageal closure status, gastric mucosal fold extension status, and positive detection rate of lesions in patients with esophageal hiatal hernia under painless gastroscopy. A total of 40 patients with esophageal hiatal hernia who underwent painless gastroscopy were screened for the use of the Sellick maneuver, in which the operator applied pressure to the cervical cricoid cartilage during the examination...

Paratracheal pressure has been recently suggested to compress and occlude the upper esophagus at the lower left paratracheal region to prevent gastric regurgitation alternative to cricoid pressure. It also prevents gastric insufflation. The aim of this randomized cross-over study was to investigate the effectiveness of paratracheal pressure on mask ventilation in obese anesthetized paralyzed patients. After the induction of anesthesia, two-handed mask ventilation was initiated in a volume-controlled mode with a tidal volume of 8 mL kg‒1 based on ideal body weight (IBW), a respiratory rate of 12 breaths min- 1 , and positive end-expiratory pressure of 10 cmH2 O...

BACKGROUND AND AIMS: Rapid Sequence Induction (RSI) is an established technique to secure the airway in patients who are at risk of aspiration. The practice of RSI in the pediatric population is highly variable due to numerous patient factors. We conducted a survey to find the prevalent practices and adherence of anesthesiologists to the practice of RSI in different pediatric age groups and whether it differs with the experience of the anesthesiologist or the age of the child. MATERIAL AND METHODS: The survey was conducted among residents and consultants attending the pediatric national anesthesia conference...

BACKGROUND: Patients arriving at the emergency department with a potential cervical spine injury and immobilized in a rigid cervical collar often require emergency airway management and rapid sequence induction intubation (RSII). There have been several advances in airway management with the advent of channeled (AirtraqⓇ ; Prodol Meditec) and nonchanneled (McGrathⓇ ; Meditronics) video laryngoscopes, which enable intubation without the removal of the cervical collar, but their efficacy and superiority over conventional laryngoscopy (Macintosh) in the presence of a rigid cervical collar and cricoid pressure have not been evaluated...

OBJECTIVE: Cricoid pressure, a manoeuver used to prevent pulmonary aspiration during rapid sequence induction, can result in deterioration of laryngeal view and increased haemodynamic changes. Its effect on laryngoscopy force remains unevaluated. The study aimed to assess the impact of cricoid pressure on laryngoscopy force and intubation characteristics during rapid sequence induction. METHODS: Seventy American Society of Anaesthesiologists I/II patients, both sexes, aged 16-65, having non-obstetric emergency surgery were randomly assigned to the cricoid group, which received 30 N cricoid pressure during rapid sequence induction, and the sham group, which received 0 N pressure...

BACKGROUND AND AIMS: The application of cricoid pressure (CP) for rapid sequence induction is questioned on two grounds: its effectiveness in clinical settings and its impact on the laryngeal view. The main reason cited for its ineffectiveness is the lack of knowledge and training in its correct application. This study assessed, the performance of anesthetists in applying effective CP in a clinical setting. MATERIAL AND METHODS: Eighty-five ASA I/II adult patients posted for elective surgery requiring oral endotracheal intubation with nasogastric tube (NGT) placement participated in the study...

The critical medicine residency training in China started in 2020, but no investigation on the practice of tracheal intubation in ICUs in China has been conducted. A survey was sent to the adult ICUs in public hospitals in Shenzhen (SZ) city and Xinjiang (XJ) province using a WeChat miniprogram to be completed by intensive care physicians. It included questions on training on intubation, intubation procedures, and changes in the use of personal protective equipment due to COVID-19. We analyzed 301 valid questionnaires which were from 72 hospitals...

Selection and insertion of an endotracheal tube (ETT) of appropriate size for airway management during general anesthesia in pediatric patients is very important. A very small ETT increases the risk of inadequate ventilation, air leakage, and aspiration, whereas a very large ETT may cause serious complications including airway damage, post-intubation croup, and, in severe cases, subglottic stenosis. Although the pediatric larynx is conical, the narrowest part, the rima glottidis, is cylindrical in the anteroposterior dimension, regardless of development, and the cricoid ring is slightly elliptical...

Background Nasogastric tube insertion is a routinely performed technique in anesthetized and intubated patients. However, failure leads to repeated insertion attempts causing injury, which makes the situation cumbersome. Therefore, we introduce a simple technique of deflating endotracheal tube cuff for nasogastric tube insertion in such patients. Methods Eighty adult patients scheduled for elective abdominal surgeries were randomly allocated into two groups, Group A (nasogastric tube insertion without endotracheal cuff deflation) and Group B (nasogastric tube insertion with endotracheal tube cuff deflation) along with lateral pressure application at cricoid in both groups...

There are no studies evaluating the effect of left paratracheal pressure (PP) on difficulty of intubation using Pentax Airway Scope (Pentax), so we conducted this study to show that PP was not inferior to cricoid pressure (CP) in intubation time using the Pentax. Patients aged 19-70 years, with an American Society of Anesthesiologists physical status 1 or 2, and undergoing otorhinolaryngological, gynecological surgery, and cholecystectomy at a single university hospital were enrolled. Intubation was performed using the Pentax under PP or CP of 30 N...

(1) Background: Rapid sequence induction (RSI) is carried out by anaesthetists to secure the airway promptly in patients who are at risk of aspirating gastric content during induction of anaesthesia. RSI requires variation in the paediatric population. We conducted a survey to investigate current practice of paediatric RSI by anaesthetists. (2) Methods: A descriptive, contextual, cross-sectional research design was followed. The study population consisted of all anaesthetists working in the Department of Anaesthesia at the University of the Witwatersrand...

OBJECTIVES: It is thought that many infants have a prominent venous plexus of the postcricoid area. In the past this entity had occasionally been reported as a postcricoid hemangioma or even a postcricoid mass. The term postcricoid cushion is now gaining acceptance to describe the prominent venous plexus of the posterior cricoid area. Although it rarely causes symptoms, it should be considered when patients present with symptoms of obstruction. Differentiating between normal variant postcricoid prominent venous plexuses, hemangiomas, and vascular malformations can be difficult and cannot be confirmed without immunohistochemistry...

BACKGROUND: The use of cricoid compression to prevent insufflation remains controversial, and its use in children is limited. This study aimed to examine the effect of real-time ultrasound-guided esophageal compression on the prevention of gastric insufflation. METHOD: This prospective observational study was conducted with fifty children aged < 2 years undergoing general anesthesia. Patients were excluded if they were at an increased risk for gastric regurgitation or pulmonary aspiration...
