Adding neuraxial to general anesthesia (GA) has been associated with improved perioperative outcome after orthopedic surgery. Presuming a similar effect in major abdominal surgery we studied its effect on perioperative outcome in open colectomy patients. ⋯ We found no clear pattern of consistent favorable results for patients undergoing their open colectomy under GNA. Further prospective research is needed to help identify those who are more likely to benefit from GNA use and its mechanism of actions.

In children, severe, life-threatening traumatic injuries of the thoracic aorta can be seen after motor vehicle collisions (MVCs) resulting in a sudden deceleration. Concurrent injuries in the thorax and abdomen can make treatment prioritization difficult and require early recognition and prompt intervention. With the increased utilization of minimally invasive endovascular approaches to traumatic aortic (TA) injuries, patients are often spared the increased surgical morbidity (spinal cord ischemia and renal insults) that can be seen with an open technique. The aim of this study was to evaluate a single American College of Surgeons level 1 pediatric trauma center's 22-y experience with TA injuries in children. ⋯ TA injuries are an uncommon injury in children and can result from MVCs or other sudden deceleration mechanisms. Surgical intervention is required in most of the cases and can be performed safely and effectively with low morbidity using an endovascular approach, which is the evolving approach of choice for thoracic aortic injuries. Lengthy follow-up care is recommended in children treated with an endovascular device to monitor for endoleaks and device complications.

Spinous process deviation is a common variation in lumbar spine, and some authors suggest that spinous process deviation may lead to imbalance between muscles on either side of the spinous process. We assume that spinous process deviation may be correlated to the disc degeneration in lumbosacral segment; however, no studies have been published in this regard. ⋯ The deviation of spinous process does not correlate to the degeneration of intervertebral disc in lumbosacral segments.

Randomized Controlled Trial Comparative Study
Propofol increases preload dependency in septic shock patients.
Predicting fluid responsiveness is crucial for fluid administration in septic shock patients. Midazolam and propofol decrease vascular tone and venous return, which may influence preload dependency. However, little is known about the effects of these two sedatives on preload dependency in septic shock patients. We evaluated the effects of sedation with propofol or midazolam on preload dependency in septic shock patients who have been fluid resuscitated. ⋯ In titrating the sedation level from a Ramsay 3 score to a Ramsay 4 score, propofol but not midazolam increased preload dependency in septic shock patients with fluid nonresponsiveness.

Comparative Study
Continuous versus interrupted suture techniques of pancreaticojejunostomy after pancreaticoduodenectomy.
Postoperative pancreatic fistula (POPF) has traditionally been a source of significant morbidity and potential mortality after pancreaticoduodenectomy (PD). Both patient-derived and technical factors contribute to pancreatic anastomotic failure. The continuous suture duct-to-mucosa pancreaticojejunostomy (PJ) described previously is associated with a low rate of POPF. The aim of the present study was to observe whether the new technique would effectively reduce the POPF rate in comparison with conventional interrupted suture duct-to-mucosa PJ. ⋯ The continuous suture duct-to-mucosa PJ effectively reduces the POPF rate after PD in comparison with interrupted anastomosis. The results confirm increased POPF rates in patients with pancreatic duct diameter <3 mm compared with pancreatic duct diameter ≥ 3 mm.
