ABSTRACT
OBJECTIVES: Airway management in children with cervical spine may make direct laryngoscopy difficult. Video laryngoscopy is an alternative to direct laryngoscopy. The GlideScope video laryngoscope, successfully used in expected and unexpected difficult pediatric airway situations, has not been studied so far in children with cervical spine immobilization. METHODS: A total of 23 children underwent laryngoscopy with manual cervical spine immobilization using the GlideScope and a direct laryngoscope (Miller 1 or Macintosh 2 blade). Percentage of glottis opening score, Cormack-Lehane score, and time to best view were recorded. RESULTS: Percentage of glottis opening score using the GlideScope was 50% (1%-87%) and 90% (60%-100%) using direct laryngoscopy (P < 0.001). Cormack-Lehane score using the GlideScope was 1 (1-2.7) and 1 (1-1) in direct laryngoscopy (P < 0.001). Time to best view with the GlideScope was 21 seconds (12.2-28 seconds) and 7 seconds (6-8.7 seconds) in direct laryngoscopy (P < 0.05). Data are presented as median and interquartile range and analyzed using paired t test. CONCLUSIONS: In simulated difficult pediatric airway, using the GlideScope resulted in a significantly declined view to the glottic entrance. This result is in contrast to studies in children with difficult airway anatomy due to an anterior larynx, where the GlideScope resulted in improved views.

Background: Ruptured middle colic artery aneurysm is extremely uncommon. Diagnosis can be challenging, as symptomatology can be attributed to more common abdominal pathologies. Due to the rarity of this condition, only case reports are available to inform management. Case Presentation: We present the case of a 72-year-old woman with a ruptured middle colic artery aneurysm presenting with signs and symptoms more suggestive of acute calculous cholecystitis. Her co-existing bleed was confirmed on CT angiogram. Coil embolization was initially attempted unsuccessfully. She underwent laparotomy, a middle colic artery ligation, and extended right hemicolectomy with intra-aortic balloon placement for emergency proximal vascular control. Post-operatively, she had a re-bleed that was successfully managed with covered stent placement in the proximal superior mesenteric artery after an unsuccessful re-attempt at coil embolization. Her apparent associated cholecystitis was managed with antibiotics and resolved uneventfully. Conclusion: A middle colic artery aneurysm can be challenging to diagnose and treat. Management options include endovascular techniques, open surgery, or a combination approach. Intra-aortic balloon placement for emergency vascular control is a novel approach that could avoid hemorrhage when intra-abdominal vascular access is challenging.
ABSTRACT
BACKGROUND: The present study generated a risk model and an easy-to-use scorecard for the preoperative prediction of in-hospital mortality for patients undergoing redo cardiac operations. METHODS: All patients who underwent redo cardiac operations in which the initial and subsequent procedures were performed through a median sternotomy were included. A logistic regression model was created to identify independent preoperative predictors of in-hospital mortality. The results were then used to create a scorecard predicting operative risk. RESULTS: A total of 1,521 patients underwent redo procedures between 1995 and 2010 at a single institution. Coronary bypass procedures were the most common previous (58%) or planned operations (54%). The unadjusted in-hospital mortality for all redo cases was higher than for first-time procedures (9.7% vs. 3.4%; p<0.001). Independent predictors of in-hospital mortality were a composite urgency variable (odds ratio [OR], 3.47), older age (70-79 years, OR, 2.74; ≥80 years, OR, 3.32), more than 2 previous sternotomies (OR, 2.69), current procedure other than isolated coronary or valve operation (OR, 2.64), preoperative renal failure (OR, 1.89), and peripheral vascular disease (PVD) (OR, 1.55); all p<0.05. A scorecard was generated using these independent predictors, stratifying patients undergoing redo cardiac operations into 6 risk categories of in-hospital mortality ranging from <5% risk to >40%. CONCLUSIONS: Reoperation represents a significant proportion of modern cardiac surgical procedures and is often associated with significantly higher mortality than first-time operations. We created an easy-to-use scorecard to assist clinicians in estimating operative mortality to ensure optimal decision making in the care of patients facing redo cardiac operations.
