Anaesthesia Management of a Patient with Hereditary Angioedema with Prophylactic Administration of C1 Esterase Inhibitor: Case report and literature review.

Hereditary angioedema (HAE) is a rare disorder caused by a deficiency of C1 esterase inhibitor. Minor trauma and emotional stress are the most common initiating events leading to contact system activation and excessive uncontrolled bradykinin release. This manifests as angioedema, a vascular reaction of the deeper layers of the skin and mucous membranes, with vasodilatation and increased permeability resulting in tissue swelling.

Esophageal bezoar formation due to solidification of enteral feed administered through a malpositioned nasogastric tube: case report and review of the literature.

Enteral feeding is now standard and routine practice in intensive care. The use of a nasogastric tube for enteral feeding is generally considered to be safe, but tubes with small bores can sometimes lead to aspiration or passage clogging when malpositioned in sedated patients who are on long-term mechanical ventilation. Thus, accurate confirmation of correct placement is mandatory in such patients.
