Importance of Sniff Nasal Pressure (SNIP) as predictor of nocturnal respiratory function in amyotrophic lateral sclerosis (ALS)
2019
Background: In ALS, respiratory disturbances during sleep have an important role in the natural history of the disease. Diurnal and nocturnal blood gases are weakly correlated, but nocturnal respiratory disorders are difficult to predict. Aim: To evaluate if SNIP, an important parameter reflecting respiratory muscle strength, is related to nocturnal respiratory disorders and whether it contributes to predict nocturnal blood gas alterations in addition to daytime blood gas levels in ALS. Methods: Forty patients with ALS, after a daytime respiratory function evaluation, including arterial blood gases and SNIP, underwent a polysomnography with transcutaneous capnography (tcPCO2). The patients …
Recommended practice for out-of-hospital emergency anaesthesia in adults: Statement from the Out-of-Hospital Emergency Anaesthesia Working Group of t…
2016
Emergency anaesthesia is an important therapeutic measure in out-of-hospital emergency medicine. The associated risks are considerably higher than those of in-hospital anaesthesia. The primary objectives of emergency anaesthesia are hypnosis, analgesia, oxygenation and ventilation through airway management. The secondary objectives of emergency anaesthesia are amnesia, anxiolysis, the reduction of oxygen consumption and respiratory work, the protection of vital organs and the avoidance of secondary myocardial and cerebral damage. A critical evaluation of the indications for outof- hospital emergency anaesthesia must take into consideration patient, case and provider-related factors. Rapid s…
Die CO 2 -Messung im Atemgas
1997
UNLABELLED Currently, even in prehospital emergency medicine (PEM), continuous end-tidal CO2 monitoring is frequently used as a sensitive and non-invasive technique in ventilated patients. Due to its central role, the continuous measurement of exhaled CO2 provides immediate information about the status of three essential functions of the organism: ventilation, circulation, and metabolism. METHODS Recent literature, obtained by a computer-guided search (Winspirs), and product information of all currently available capnometry devices were reviewed in detail. Firstly, the theoretical background of different CO2-measurement methods and techniques is described. Secondly, indications and specific…
Subglottic stenosis imitating the carina – a case report of airway mimicry
2021
Summary We present a case of awake tracheal intubation with flexible bronchoscopy which resulted in incorrect tracheal tube placement. The presence of a stenotic subglottic lesion with an appearance similar to the carina led to the tube being positioned with only the tip within the trachea whilst the cuff was located between the vocal cords. A capnography trace was identified before induction of anaesthesia; however, visual confirmation of the carina was undertaken in a rushed manner due to the patient becoming agitated. Once the incorrect tracheal tube placement was identified, the decision was made to wake the patient. Thereafter, a more experienced operator successfully performed awake t…
