In Brief BACKGROUND: The cricothyroid membrane (CTM) is the recommended site of access to airway during cricothyroidotomy provide emergency oxygenation. Despite apparent simplicity technique, this rescue maneuver frequently fails achieve its goals and complications are numerous. reasons for failure unclear. We sought determine ability physicians correctly identify CTM in female patients. METHODS: Using fluorescent "invisible" ink, physician was asked mark with patient supine neutral position...
During mechanical ventilation, lung recruitment attenuates injury caused by high VT, improves oxygenation, and may optimize pulmonary vascular resistance (PVR). We hypothesized that ventilation without would induce in otherwise healthy lungs. Anesthetized rats were ventilated with conventional (VT 8 ml/kg; respiratory frequency 40 per minute) 21% inspired oxygen, or a strategy consisting of maneuvers plus positive end-expiratory pressure, the presence absence laparotomy. Additional...
The cricothyroid membrane (CTM) is the recommended site of access to airway during cricothyrotomy provide emergency oxygenation. We sought compare ability physicians correctly identify CTM in male and female patients. In a prospective observational study, anaesthetists were asked locate by palpation which was then identified using ultrasound distance between actual estimated margin measured. Participants assessed ease visual analog scale. second series, angulation posterior junction thyroid...
In Brief It may be required to ensure patency of the airway in lateral position certain circumstances. We performed a prospective randomized clinical trial investigating effects left patient positioning on anatomy and subsequent management. Laryngoscopic examination was anesthetized patients, supine positions, presence absence cricoid pressure. Patients were management via an endotracheal tube or laryngeal mask (LMA). The resulted deterioration laryngoscopic view 35% patients improvement...
In Brief Epinephrine may be detrimental in cardiac arrest. this laboratory study we sought to characterize the effect of epinephrine and concomitant calcium channel blockade on postresuscitation myocardial performance after brief asphyxial Anesthesized rats were disconnected from mechanical ventilation, resulting Resuscitation was attempted 1 min with oxygen, chest compressions, IV medication. experimental series 2, animals allocated 10 or 30 μg/kg 0.9% saline. 3, received randomized 0.1...
In Brief Cricothyroidotomy is the final rescue maneuver in difficult airway management. We compared 4 techniques of oxygenation via cricothyroid membrane a manikin. The were wire guided, trocar, cannula with jet ventilation, and blade technique (scalpel endotracheal tube). wire-guided group, time taken to ventilation was slower on all attempts, there no successful attempts <40 seconds. There differences between other groups at any time. Time improved repetition groups. Skills retained 1...
Emergency front of neck airway is a recommended rescue strategy in children over 1 year old. Surgical tracheostomy advocated as the first-line technique, but absence an ear, nose and throat surgeon cricothyroidotomy or proposed. Recent research shows that clinical identification cricothyroid membrane frequently inaccurate older adults has prompted investigation ultrasound potential tool for emergency airway. Advance knowledge dimensions pediatric may assist clinicians determining feasibility...
Abstract Background Emergency front of neck access in a “can't intubate can't oxygenate” scenario pediatrics is rare. Ideally airway rescue would involve the presence an ear, nose, and throat surgeon. If unavailable however, responsibility lies with anesthesiologist accurate identification anterior structures essential for success. Aim We assessed anesthesiologists’ accuracy pediatric cricothyroid membrane by digital palpation three predefined age groups (37 weeks to <1 year old, 1‐8...
BACKGROUND: Oxygenation via the cricothyroid membrane (CTM) may be required in emergencies, but inadvertent tracheal cannulation occur. In this study, we compared airway injury between and CTM sites using different techniques for access. METHODS: Anesthesiologists performed 4 access on excised porcine tracheas. The were 1) wire-guided (WGT), 2) trocar (TT), 3) needle cannula (NCT), 4) surgical—scalpel with endotracheal tube (ST). Participants each technique at both sites. Specimens assessed...
Multiple interventions have been tested in models of cardiopulmonary resuscitation (CPR) to optimize drug use, chest compressions, and ventilation. None has studied the effects positive end-expiratory pressure (PEEP) on outcome. We hypothesized that because PEEP can reverse pulmonary atelectasis, lower vascular resistance, potentially improve cardiac output, its use during CPR would increase survival.Anesthetized Sprague-Dawley rats were exposed 1 min asphyxial arrest. Resuscitation was...
High Flow Nasal Oxygen (HFNO) therapy offers a proven means of delivering respiratory support to critically ill patients suffering from viral illness such as COVID-19. However, the has potential modify aerosol generation and dispersion patterns during exhalation thereby put healthcare workers at increased risk disease transmission. Fundamentally, gap exists in literature with regards effect on fluid dynamics jet which is essential understanding aerosols hence quantifying transmission posed...
