A&A practice
-
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
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.

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.

Perioperative Extracorporeal Cardiopulmonary Resuscitation: The Defibrillator of the 21st Century?: A Case Report.
Veno-arterial-extracorporeal membrane oxygenation (ECMO) for cardiopulmonary resuscitation (ECMO-CPR) has been recommended by new resuscitation guidelines in the United Kingdom. Our recently established yet unfunded ECMO-CPR service has thus far treated 6 patients, with 3 making a good recovery. ⋯ We argue for a pragmatic approach to funding of ECMO-CPR because observational evidence suggests superiority over traditional resuscitation and there exists major methodological and ethical barriers to randomized controlled studies. We also call for high-quality observational evidence in the perioperative setting.
