Complex cyanotic congenital heart disease and cervical spine surgery: Ticking all the right boxes.

Although complex congenital heart disease (CHD) patients usually present in childhood, it is not rare to see adults well past middle age. These patients undergo continuous pathophysiological changes in their heart and blood vessels, making anesthetic management more challenging if surgery is required. Herein, we report a case in which understanding the anatomy and pathophysiology helped optimally manage a patient with a double outlet right ventricle (DORV) who underwent plating and fixation for a hangman's fracture in the prone position.

Utility of the Awake Video Laryngoscopy Assisted Fibreoptic Intubation Technique in Maxillofacial Gunshot Injury - A Case Report.

Rationale: Maxillofacial gunshot injury leads to significant soft tissue and bone defects, which compromise airway patency, thus posing a challenge for the anaesthesiologist. The utility of the videolaryngoscopy-assisted fibreoptic intubation (VAFI) technique in maxillofacial gunshot injury has not yet been described in the literature. Patient Concerns: We report the case of a young male presenting with extensive maxillofacial wounds with fractures of the bilateral maxilla, mandible and floor of orbit secondary to self-inflicted gunshot injury. Diagnosis: Major peri-operative concerns included anticipated difficult airway, control of potential haemorrhage and airway oedema. Treatment: A flexible fibreoptic bronchoscope used in combination with a video laryngoscope was used to successfully secure the airway. Outcome: He was extubated on the same day and discharged after two weeks. Take-Away Lessons: The current case highlights the safe and effective use of the videolaryngoscopy-assisted fibreoptic intubation technique in maxillofacial gunshot injury.

A TBADT photocatalyst-enabled radical-induced cyclization pathway to access functionalized dihydrobenzofurans.

Herein, this work describes a photoinduced visible light-mediated radical cyclization for constructing dihydrobenzofuran (DHB) scaffolds. Notably, this cascade photochemical process is tolerable with various aromatic aldehydes and diverse alkynyl aryl ethers and proceeds via an intramolecular 1,5-hydrogen atom transfer (HAT) pathway. Significantly, acyl C-H activation under mild conditions has been achieved without the use of additives or reagents. The photocatalyst, tetrabutylammonium decatungstate (TBADT), plays an important role in the present strategy by facilitating the well-known hydrogen atom transfer during the course of the reaction.
