RESUMEN

BACKGROUND: The appropriate use of narcotics for postoperative pain control is controversial because of potential medication-induced complications. The authors sought to determine the effects of narcotics in the pediatric population following cranial vault remodeling operations. METHODS: A retrospective review was performed on 160 consecutive patients who underwent cranial vault remodeling for craniosynostosis. RESULTS: There was a statistically significant difference in total morphine equivalents in the group that experienced no emesis and those with at least one episode of emesis (0.97 morphine equivalents/kg versus 1.44 morphine equivalents/kg; p = 0.05). There was a statistically significant difference in hospital morphine equivalents in the group with documented respiratory events (average, 2.3 morphine equivalents/kg versus 1.3 morphine equivalents/kg in the nonevent group; p = 0.006). The patients who received dexmedetomidine had a trend toward a decrease in hospital narcotic administration with equivalent pain control (1.2 morphine equivalents/kg versus 1.9 morphine equivalents/kg; p = 0.09). There was a statistically significant positive correlation between total morphine equivalents for the hospitalization and hospital stay ( r = 0.27, p = 0.001). The amount of morphine equivalents used in the first 24 hours was also found to be an independent predictor of a respiratory event ( p = 0.002 by multivariate logistic regression). Independent positive predictors of hospital stay were age ( p < 0.001), intensive care unit time ( p < 0.001), and total morphine equivalents for the hospitalization ( p = 0.001) by multivariate analysis with linear regression. CONCLUSION: The authors' study demonstrates improvement in outcomes with decreased use of narcotics, which establishes that there is a need to further explore postsurgical recovery outcomes with multimodal pain control. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.

RESUMEN

INTRODUCTION: This study investigated whether a novel therapy called ischemic conditioning (IC) improves walking capacity and lower extremity muscle performance in patients with peripheral vascular disease who experience intermittent claudication. METHODS: Forty-three patients with claudication were enrolled and received either IC or IC Sham for 2 weeks in this randomized, controlled, double-blinded, prospective study. IC sessions involved five cycles of alternating 5-min inflations of a blood pressure cuff to 225 mm Hg (25 mm Hg for IC Sham) and 5-min deflations, around the thigh of the affected lower extremity. RESULTS: There was no difference in the change in claudication onset time (Δ = 114 ± 212 s IC vs. 104 ± 173 s IC Sham; p = 0.67) or peak walking time (Δ = 42 ± 139 s IC vs. 12 ± 148 s IC Sham; p = 0.35) between the IC and IC Sham groups. At the level of the knee, participants in the IC group performed more work (Δ = 3,029 ± 4,999 J IC vs. 345 ± 2,863 J IC Sham; p = 0.03) and displayed a greater time to muscle fatigue (Δ = 147 ± 221 s IC vs. -27 ± 236 s IC Sham; p = 0.01). DISCUSSION/CONCLUSION: In patients with claudication, IC improved total work performed and time to fatigue at the knee but did not change walking parameters.

RESUMEN

Systemic sclerosis-polymyositis overlap syndrome is rare in children. Anti-PM/Scl is the most common autoantibody associated with this syndrome. We present a case of systemic sclerosis-polymyositis overlap syndrome in a child with isolated anti-Ku antibodies, an uncommon antibody associated with this rare syndrome.

RESUMEN

The majority of abdominal aortic aneurysms have been treated by endovascular aneurysm repair in the past decade. Common perioperative complications after this procedure are mostly related to vascular access and improper stent-graft placement. We present the first case of bilateral lower extremity claudication due to severe angulation of the graft-aorta interface, which may have been prevented by a more critical consideration of the patient's anatomy. Treatment required open explantation and repair of the abdominal aortic aneurysms which led to complete resolution of claudication. The results of this case highlight the importance of adherence to instructions for use guidelines.

RESUMEN

Although management paradigms for certain arterial trauma, such as aortic injuries, have moved towards an endovascular approach, the application of endovascular techniques for the treatment of peripheral arterial injuries continues to be debated. In the realm of peripheral vascular trauma, popliteal arterial injuries remain a devastating condition with significant rates of limb loss. Expedient management is essential and surgical revascularization has been the gold standard. Initial clinical assessment of vascular injury is aided by readily available imaging techniques such as duplex ultrasonography and high resolution computed tomographic angiography. Conventional catheter based angiography, however, remain the gold standard in the determination of vascular injury. There are limited data examining the outcomes of endovascular techniques to address popliteal arterial injuries. In this review, we examine the imaging modalities and current approaches and data regarding endovascular techniques for the management popliteal arterial trauma.
