Ultrasonography has been suggested as a useful noninvasive tool for the detection of hypovolemia in critically ill patients. Hypovolemia after preoperative fasting and bowel preparation may compromise hemodynamic function during gastrointestinal surgery. However, there are few data comparing ultrasonographic examination of the inferior vena cava (IVC) diameter with central venous pressure (CVP) measurement in patients undergoing gastrointestinal surgery in the assessment of intravascular volume status. ⋯ Our data demonstrate that the IVC and RV diameters are consistently low in patients undergoing gastrointestinal surgery when compared with healthy subjects. Ultrasonographic measurements of the IVC and RV diameters are useful supplement of CVP for the evaluation of preoperative patients with hypovolemia.

Persistent and recurrent hyperparathyroidism necessitate reoperation, which is associated with increased procedure-specific complication rates. The effect of reoperative parathyroidectomy on more generalized outcomes is poorly understood. We sought to determine patient, provider, and perioperative characteristics associated with reoperation, as well as to determine the associated risks. ⋯ Obesity and an American Society of Anesthesiologist 3 classification are independently associated with reoperation. Readmission within 30 d is associated with reoperation and is a target for patient education and quality improvement after this procedure.

Resuscitative endovascular balloon occlusion of the aorta (REBOA) is a hemorrhage control and resuscitative adjunct that has been demonstrated to improve central perfusion during hemorrhagic shock. The aim of this study was to characterize the systemic inflammatory response associated and cardiopulmonary sequelae with 30, 60, and 90 min of balloon occlusion and shock on the release of interleukin 6 (IL-6) and tumor necrosis factor alpha. ⋯ REBOA is a useful adjunct in supporting central perfusion during hemorrhagic shock; however, increasing occlusion time and shock results in a greater IL-6 release. Clinicians must anticipate inflammation-mediated organ failure in post-REBOA use patients.

Falls from ladders account for a significant number of hospital visits. However, the epidemiology, injury pattern, and how age affects such falls are poorly described in the literature. ⋯ Older people are particularly vulnerable after falling from ladders. Although they fell from lower heights, the elderly sustained different and more severe injury patterns. Ladder safety education should be particularly tailored at the elderly.

Ex vivo normothermic perfusion (EVNP) can reverse some of the detrimental effects of ischemic injury. However, in kidneys with warm and cold ischemic injury the optimal perfusion pressure remains undetermined. The aim of this study was to evaluate the effects of two different arterial pressures during EVNP. ⋯ A mean arterial pressure of 75 mm Hg during EVNP resulted in less tubular damage and less endothelial injury during ex vivo reperfusion compared with kidneys perfused at 55 mm Hg.
