This pilot randomized controlled trial shows that thoracoscopic repair of CDH is associated with prolonged and severe intraoperative hypercapnia and acidosis, compared with open surgery. These findings do not support the use of thoracoscopy with CO2 insufflation and conventional ventilation for the repair of CDH, calling into question the safety of this practice. The effect of thoracoscopy on blood gases during repair of EA/TEF in neonates requires further evaluation. (ClinicalTrials.gov Identifier: NCT01467245).

Summary Background Donohue syndrome is a rare autosomal recessive disorder of insulin resistance, causing a functional defect in insulin receptor function, and affecting the ability of the insulin to bind the receptor. Features include severe hyperinsulinism and fasting hypoglycemia, along with severe failure to thrive despite feeding. An accelerated fasting state results in muscle wasting, decreased subcutaneous fat, and an excess of thick skin. A reduced thoracic diameter is accentuated by increased abdominal distension, which impacts on respiratory reserve. Cardiac disease develops early in life, with progressive hypertrophic cardiomyopathy as a result of hyperinsulinism. Prognosis is poor with the majority of patients dying in infancy of sepsis. The aim of this review is to report our experience of providing anesthesia for patients with Donohue syndrome, and inform guidance for safe management of these children, based on a comprehensive literature review. Methods A literature search was carried out using PubMed, Medline, and the Cochrane Library, and using the MESH search terms detailed below. Patients were identified by formal request to the department of pediatric endocrinology at Great Ormond Street Hospital. Each patient's notes were searched manually and electronically for both clinical presentation and outcome, and anesthesia records. Discussion There is currently no published literature relating to anesthetic management of Donohue syndrome. We report a case series of 5 patients with Donohue syndrome who have presented to our institution. This small series of children with this complex disorder demonstrates a clearly increased risk of general anesthesia. Many of the risks relate to restrictive lung disease and abdominal distension which worsens with bag valve mask ventilation and limited respiratory reserve which leads to precipitous desaturation. During induction, a spontaneously breathing technique is recommended. If required, bag valve mask ventilation should be accompanied by constant gastric aspiration. Intubation is challenging, and a difficult airway plan, including a second experienced anesthetist and ENT support, should be in place. These children are predisposed to developing cardiomyopathy and therefore at risk of cardiovascular collapse under anesthesia.

Difficult intubation of a 2.4 kg ex premature, suspected Pierre Robin Sequence with upper airway obstruction causing respiratory failure. Multiple failed intubation attempts by an experienced pediatric anesthetist using described techniques and adjuncts. A description of a simple new maneuvre using a GlideScope and a stylet. By twisting the stylet into a spiral shape, the endotracheal tube was given improved maneuverability that allowed the intubator to place the endotracheal tube tip to the glottis opening. Then by rotating the tube in a clockwise direction it could be manipulated past the vocal cords into the trachea.
