Novel Preoxygenation Technique to Deliver High-Flow Oxygen in a Patient With Facial Trauma: A Case Report.
This case demonstrates a novel preoxygenation technique in a patient with difficult access to the airway after a traumatic facial injury. To find a solution, a fusion of oxygenation equipment was trialed by altering and combining a tracheostomy mask and the tubing of an Optiflow circuit from which the nasal cannula component had been removed. ⋯ Effective preoxygenation was confirmed by arterial gas measurements. This study supports the use of this novel Optiflow-tracheostomy mask fusion device in appropriately selected cases.

Surgery requires many electrically driven devices. Three events occurred recently in an operating room (OR) suite circa the 1980s wherein circuit breakers tripped due to overloaded circuits. This led to us to (1) increase OR electric capacity; (2) record each instrument's power requirements, map their OR location, and determine when during surgery they were used; (3) provide users with instruction and diagrams into which outlet to plug each instrument. When introducing surgeries requiring devices, especially with high electrical power (current or amperage) demands, or renovating older or planning new ORs, it is important to provide ORs with sufficient electric current, circuits, and outlets.

We present a rarely described complication of unilateral rhinorrhea and sneezing in a patient who received intravenous sedation with propofol and supplemental oxygen via a nasal cannula during upper gastrointestinal endoscopy. The literature is reviewed and a mechanism is proposed. Mechanical irritation of the nasal mucosa is felt to be the trigger. Suggestions to avoid and to treat are offered.

We report a case of cesarean hysterectomy in a parturient with morbidly adherent placenta that was complicated by an estimated blood loss of 25 L, with the usage of massive transfusion protocols. On the third postoperative day, symptomatology suggestive of a stroke was elicited. ⋯ She showed gradual recovery in the following months with almost complete return to baseline function. We present this case to highlight vertebral artery dissection as a potential complication after peripartum massive blood transfusion and to consider the management decisions this scenario presents.

There have been many advances in the management of acute respiratory distress syndrome, a condition which Bellani et al, in the LUNG SAFE trial (Large Observational Study to Understand the Global Impact of Severe Acute Respiratory Failure), found represents up to 10.4% of intensive care unit admissions and 23.4% of patients requiring mechanical ventilation, with an unadjusted intensive care unit and hospital mortality of 35.3% and 40%, respectively. Studies have shown that prone positioning can improve oxygenation in patients who are mechanically ventilated for acute respiratory distress syndrome. This case report describes an example in which intraoperative prone positioning improved oxygenation in a patient after aspiration of gastric contents on induction of general anesthesia.
