Usefulness of pre-operative copeptin concentrations to predict post-operative outcome after major vascular surgery.

The aim of this study was to investigate whether preoperative determination of plasma copeptin levels in addition to plasma N-terminal pro-B-type natriuretic peptide (NT-pro-BNP) could help improve risk stratification in patients who undergo major vascular surgery. One hundred ninety-eight consecutive patients who underwent major vascular surgery (58.6% infrainguinal aortic reconstruction, 23.

Arterial line in prehospital emergency settings - A feasibility study in four physician-staffed emergency medical systems.

Background And Aim Of The Study: Arterial lines are widely used in operating rooms, critical care and emergency departments. Although invasive arterial blood pressure monitoring and arterial blood gas analysis are prehospitally available, the use of arterial lines in the field remains an exception. This study evaluates the feasibility, indications and therapeutic consequences of prehospital arterial line insertion.

Outcome of type C (AO) distal humeral fractures: follow-up of 22 patients with bicolumnar plating osteosynthesis.

Background: In the last 40 years, 220 patients with type C distal humeral fractures (AO13-C1-3) were treated at our hospital operatively. Aim of this study is to present results of patients treated by dual plating osteosynthesis in the last decade and to compare them with our previous series (A-C).

Materials And Methods: From 1999 to 2008, 48 distal humeral fractures were treated operatively by perpendicular dual plating osteosynthesis.

Tight control of effectiveness of cardiac massage with invasive blood pressure monitoring during cardiopulmonary resuscitation.

The continuity of chest compression is the main challenge in prehospital cardiopulmonary resuscitation in the field as well as during transport. Invasive blood pressure monitoring with visible pulse waves by means of an arterial line set prehospitally allows for tight control of the effectiveness of chest compressions as well as of the impact of the administered epinephrine and also captures beginning fatigue of the rescuers. In this case, maintaining uninterrupted circulation through manual as well as mechanical chest compressions continued until the successful percutaneous coronary intervention saved the patients life without neurologic damage.

Penetrating neck trauma causing tracheal rupture, spinal cord injury, and massive pneumocephalus.

We describe a case in which tracheal, esophageal, and spinal cord injuries associated with massive pneumocephalus were caused by a flying chainsaw segment. To our knowledge, this is the first such case reported in the medical literature. The management challenges inherent in this exceedingly rare combination of injuries are discussed, and a novel theory explaining the possible pathophysiological mechanism that led to pneumocephalus in our patient is put forth.

Transdiaphragmatic repositioning of the heart in the setting of emergency laparotomy after blunt trauma.

Cardiac luxation after blunt trauma is a rare condition that carries a high mortality rate. We report a case of a left pericardial rupture with partial dislocation of the heart into the left pleural cavity and cardiac strangulation in a polytraumatized patient after a severe motor vehicle accident. This case is of special interest because the patient not only had cardiovascular compromise but was also actually in cardiac arrest and being resuscitated when an emergency repositioning of the heart through the diaphragm in the setting of damage control laparotomy restored circulation.

The relationship between short-term mortality and quality of care for hip fracture: a meta-analysis of clinical pathways for hip fracture.

Objectives: To assess the association between use of clinical pathways for hip fracture and changes in the rates of five inpatient complications and short-term mortality.

Design: Meta-analysis of published studies examining clinical pathways for hip fracture, identified through systematic searches of electronic databases (MEDLINE, EMBASE, CINAHL, and Cochrane Central Register of Controlled Trials) and hand searches of selected article bibliographies.

Setting: Observational and interventional studies of clinical pathways for hip fracture examining rates of deep venous thrombosis, pressure ulcer, surgical site infection, urinary tract infection, pneumonia, and inpatient or 30-day mortality.

Revised Cardiac Risk Index (Lee) and perioperative cardiac events as predictors of long-term mortality in patients undergoing endovascular abdominal aortic aneurysm repair.

Objective: To determine if the Revised Cardiac Risk Index (Lee) is useful for stratification of patients by risk of both perioperative cardiac morbidity and long-term all-cause mortality in the setting of endovascular repair of abdominal aortic aneurysms.

Design: This study was designed as a retrospective review.

Setting: It was conducted at a single academic medical institution.

Successful prolonged resuscitation involving the use of tenecteplase without neurological sequelae.

Prehospital cardiac arrest is associated with a very poor prognosis. We report a case of complete neurological recovery after prolonged resuscitation involving the use of tenecteplase in a patient with undifferentiated cardiac arrest with a return of spontaneous circulation after 1 hour of resuscitation, where basic life support was commenced immediately by a bystanding family member. Factors associated with an increased chance of survival from out-of-hospital cardiac arrest are discussed as well as the role of thrombolytics in cardiopulmonary resuscitation.

Cricothyroidotomy on the scene in a patient with severe facial trauma and difficult neck anatomy.

We present a case of a patient with severe facial trauma who was treated at the scene by a physician-staffed trauma life support team. Because of massive oropharyngeal bleeding in addition to a difficult neck anatomy in a very obese patient, a cannot-intubate, cannot-ventilate situation occurred. Control of the airway could finally be achieved by surgical cricothyroidotomy.

Levosimendan: current status and future prospects.

Purpose Of Review: While patients with acute heart failure typically receive diuretics and vasodilators, contractile dysfunction and peripheral hypoperfusion also leads to a widespread use of inotropic agents despite the lack of evidence for efficacy or safety. Levosimendan, a calcium sensitizer and vasodilator, has been proposed to be superior to standard inotropes. In addition, further possible indications for levosimendan have been described, such as perioperative use, cardioprotection, cardiogenic shock, sepsis, and right ventricular dysfunction.
