Background: Flexible bronchoscopy for tracheal intubation is indicated in patients with difficult airways, but the upper airway is frequently obstructed in sedated or anaesthetised apnoeic patients. This makes it more difficult to locate the glottis through bronchoscopy, and increases the risk of hypoxaemia. Nasal high-flow oxygenation is useful to prevent hypoxaemia during airway management, but no studies have assessed if this method of oxygenation improves the bronchoscopic view of the glottis by preventing upper airway obstruction.

Article Synopsis
  • * Combining PET and MRI enhances diagnostic accuracy by revealing abnormal brain activity and structural problems, offering a fuller picture of the epileptogenic zone.
  • * Simultaneous PET/MRI scanning minimizes sedation and radiation exposure for pediatric patients, while alternative software for co-registering images can also be helpful in presurgical evaluations.

It is largely unknown how the tongue base and soft palate deform to alter the configuration of the oropharyngeal airway during respiration. This study is to address this important gap. After live sleep monitoring of five Yucatan and two Panepinto minipigs to verify obstructive sleep apnea (OSA), eight and four ultrasonic crystals were implanted into the tongue base and soft palate to circumscribe a cubic and square region, respectively.

Caffeine - Essentials for anaesthesiologists: A narrative review.

J Anaesthesiol Clin Pharmacol

January 2023

Department of Anaesthesia, Pain Medicine and Critical Care, New Delhi, India.

Caffeine has a multitude of uses in anaesthesia, and numerous studies have evaluated its efficacy and usefulness in various aspects of anaesthesia and medical practice. Its various applications in anaesthesia include its role in awakening from anaesthesia, managing post-dural puncture headache, managing post-sedation paradoxical hyper-activity in children, post-operative bowel paralysis, and apnoea in paediatric populations, that is, apnoea in infancy, paediatric obstructive apnoea, and post-anaesthetic apnoea in pre-mature infants. Though the effects of caffeine on bronchial smooth muscle, neurological, and cardio-vascular systems are well known, the relatively little-known effects on the endocrine and gastro-intestinal (GI) system have been recently taking primacy for eliciting its therapeutic benefits.
