Ultrasound-guided femoral venous cannulation is frequently performed in neonates. Identification of femoral vessels under ultrasound navigation is unreliable and time consuming in hemodynamically unstable neonates with feeble femoral arterial pulse. ⋯ We describe 2 incidents wherein guidewires placed via femoral veins in neonates were detected in the inferior vena cava on abdominal ultrasound. We advocate abdominal inferior vena cava imaging to confirm the correct placement of a guidewire placed via femoral vein in emergency situations.

Case Reports
Traumatic Tracheobronchial Laceration Causing Complete Tracheal Resection: Challenges of Anesthetic Management.
We report the case of a 9-year-old girl who sustained blunt trauma to the chest and presented for emergent repair of a complete tracheobronchial laceration. Tracheobronchial laceration is potentially life threatening. While conservative management has been described for simple tears, more complex injuries require surgical repair. We discuss the anesthetic challenges, airway management, and ventilation options for surgical repair in a child with a complex laceration involving the tracheobronchial tree.

Cardiac vasoplegia remains a significant contributor of morbidity and mortality in cardiac surgery patients after cardiopulmonary bypass. Effective therapeutic options for vasopressor-refractory vasoplegia are limited. ⋯ Reductions in vasopressor requirements were observed in all 3 patients, and, in 2 patients, norepinephrine was completely discontinued within 24 hours. Ascorbic acid is a novel potential therapeutic option for cardiac vasoplegia that warrants rigorous prospective studies.

Case Reports
Linezolid-Induced Lactic Acidosis Sets Stage for Surgery to Rule Out Mesenteric Ischemia: A Case Report.
An 81-year-old woman with extensive peripheral vascular and coronary artery disease was admitted to the intensive care unit with a deep heel abscess and urinary tract infection. When cultures from the heel ulcer yielded vancomycin-resistant enterococci, she was started on the antibiotic linezolid. ⋯ Findings from the laparotomy were negative, and after elimination of other differential diagnoses, the metabolic acidosis was ultimately attributed to linezolid. Acidosis resolved after discontinuation of linezolid.

Fasting guidelines are used to prevent perioperative aspiration but they are only reliable in healthy elective patients. Point-of-care gastric ultrasound allows qualitative and quantitative evaluation of gastric contents at the bedside. This case report describes the use of serial gastric point-of-care ultrasound to evaluate the effect of prokinetic therapy with domperidone and erythromycin in an elective surgical patient with multiple comorbidities who presented with a full stomach.
