Uncertainty exists on how to treat patients suffering from accidental hypothermia and on the optimal transport decisions. The aim of this review is to provide an updated evidence-based reference for the pre-hospital and in-hospital management of patients with accidental hypothermia and for the transport decisions required to facilitate treatment. Advances in the efficiency and availability of rewarming techniques have improved the prognosis for patients presenting with hypothermia. For hypothermic patients with a core body temperature ≥ 28 °C without cardiac instability there is increasing evidence to support the use of active external and minimally invasive rewarming techniques (e.g. chemical, electrical or forced air heating packs, blankets and warm parenteral fluids). Hypothermic patients with cardiac instability (i.e. systolic blood pressure < 90 mmHg, ventricular arrhythmia and core body temperature < 28 °C) should be rewarmed with active external and minimally invasive rewarming techniques in a hospital which also has circulation substituting venous-arterial extracorporeal membrane oxygenation (VA-ECMO) and cardiopulmonary bypass (CBP) facilities. In cardiac arrest patients VA-ECMO may be a better treatment option than CBP and survival rates of 100 % can be achieved compared to ~ 10 % with traditional methods (e.g. body cavity lavage). Early transport to a hospital appropriately equipped for rewarming has the potential to decrease complication rates and improve survival. [ABSTRACT FROM AUTHOR]

Cardiopulmonary bypass (CPB) is a standard procedure in cardiac surgery; however, apart from its therapeutic options a CPB might also initiate systemic and organ-specific complications, such as heart failure, renal and pulmonary dysfunction, impaired coagulation as well as neurological and cognitive dysfunction. The immunological response to the extracorporeal circulation generates systemic inflammation which often meets the definition of systemic inflammatory response syndrome (SIRS). The main inducers of SIRS are contact of blood with the artificial surfaces of the CPB, mechanical stress which affects the blood components and the extensive surgical trauma. Hence, a number of technical and surgical developments aim at reduction of the inflammatory response caused by the CPB. By reason of surgical demands, the majority of cardiothoracic procedures still depend on the use of CPB; however, there is an on-going development of new techniques trying to reduce the surgical trauma and the negative consequences of CPB. Here, minimized systems with biocompatible surfaces have been shown to be effective in attenuating the inflammatory response to CPB. Alternative procedures such as off-pump surgery may help to avoid CPB-associated complications but due to specific limitations will not replace conventional bypass surgery. [ABSTRACT FROM AUTHOR]

High risk pulmonary embolism commonly presents with a variety of symptoms and is an acute life-threatening event. In patients showing unclear acute circulatory distress, pulmonary embolism should be quickly ruled out by computed tomography or echocardiography. The diagnostic steps and surgical treatment of pulmonary embolism in a 25-year-old female patient suffering from acute circulatory insufficiency resulting in cardiac arrest within 11 min after emergency hospital admission are reported. Due to the reasonable suspicion of acute right heart decompensation, systemic perfusion was re-established by cardiopulmonary bypass after cardiopulmonary resuscitation for 41 min. Sternotomy and surgical embolectomy were performed. The patient was successfully extubated the following day and despite the long resuscitation time the outcome was excellent without any neurological deficit. Recent publications addressing the advantages of primary embolectomy versus intravenous thrombolysis in acute circulatory distress caused by pulmonary embolism are discussed. Primary surgical treatment including cardiopulmonary bypass for right ventricular relief and re-establishing of systemic perfusion is recommended for patients with pulmonary embolism undergoing cardiopulmonary resuscitation.

Over 100,000 heart surgeries are performed in Germany annually. Although severe neurological complications like ischaemic strokes have meanwhile become rare occurrences, subtle neuropsychological changes are still frequently recognized after major heart surgeries. The hitherto unsolved problem of postoperative cognitive decline (POCD) is portrayed in this article. Multifactorial aetiologies including microembolism and preoperative risk factors are supposed to play a significant role in POCD. A variety of neuroprotective strategies such as intraoperative microemboli filtration have been suggested to minimize cerebral risks. The utility of neuroprotective methods has recently been verified in randomized studies. [ABSTRACT FROM AUTHOR]

Initially introduced as a rheologic agent for use in intermittent claudication due to peripheral artery disease and in ischemic cerebrovascular disease, the methylxanthine derivative pentoxifylline (PTX) has been shown to possess several anti-inflammatory properties which make this drug an interesting immunomodulating adjunct for the management of patients undergoing cardiac surgery. As an unspecific phosphodiesterase inhibitor PTX ameliorates the inflammatory response following a septic stimulus and blunts organ dysfunction after ischemia-reperfusion injury. Apart from this several small clinical studies have shown that the use of PTX may blunt the inflammatory response induced by cardiac surgery using a cardiopulmonary bypass. Additionally it has been shown that the perioperative application of this drug may improve postoperative function of organs at risk, such as the kidneys and liver. [ABSTRACT FROM AUTHOR]

Over the last two decades there has been a growing recognition that cardiac function is not solely determined by systolic but also essentially by diastolic function. Left ventricular diastolic dysfunction is characterized by an impairment of ventricular filling caused either by abnormal relaxation, an active energy consuming process or decreased compliance, which is determined by passive tissue properties of the ventricle. Doppler echocardiography, including tissue Doppler imaging, has emerged as the preferred clinical tool for the assessment of left ventricular diastolic function. Recently the importance of left ventricular diastolic function is increasingly being recognized also during the perioperative period. Newer studies have shown that after cardiopulmonary bypass there is a significant decrease in left ventricular compliance. Experimental studies have demonstrated that sepsis is associated with a decrease in both active relaxation and ventricular compliance. Initial studies are also focusing on therapeutic options for patients with isolated diastolic dysfunction. [ABSTRACT FROM AUTHOR]

Objective: The Anaesthesiological Questionnaire (ANP) is a self-rating method for the assessment of postoperative complaints and patient satisfaction. The questionnaire was adapted for use in cardiac anaesthesia (ANP-KA). The study was conducted to show the value of ANP-KA as a practicable means of assessing the patient's state after cardiac anaesthesia and for its use in quality assurance.Methods: A total of 1,688 patients from 19 clinics were included who had exclusively received heart valve surgery, CABG surgery or both operations. They completed the ANP-KA between days 1 and 8 postoperatively.Results: The ANP-KA was completed by 79.1% of the patients without any assistance. The highest incidence rates were reported for a dry mouth/thirst (85.1%) and for pain in the area of surgery (60.2%). Plausible and significant differences in patients' symptoms between the grading for the immediate postoperative period and the current state at filling in the questionnaire were found. Women reported more postoperative complaints than men but no differences were found between male and female patients with regard to satisfaction with anaesthesiological care and convalescence. More complaints were reported after heart valve surgery than after CABG and satisfaction with convalescence was significantly lower after heart valve surgery. The clinics differed with respect to the reported somatic complaints and satisfaction scales.Conclusion: The results demonstrate the practicability and validity of the ANP-KA for the assessment of postoperative complaints and patient satisfaction after cardiac surgery.

A 29-year-old primagravida developed severe chest pains during labor. An emergency caesarean section was performed as the symptoms persisted. Imaging diagnosis immediately after delivery revealed an acute proximal (type A) aortic dissection. The patient was transferred to the nearest cardiothoracic surgery centre and successful emergency surgical aortic repair was performed. The perioperative course of a type A aortic dissection during pregnancy and labor is complicated by time pressure, diagnostic restrictions until delivery and potentially fatal uterine bleeding during cardiopulmonary bypass and hypothermic cardiac arrest. This case report describes the diagnosis and the surgical, anesthesiological and gynecological management of this life-threatening peripartum complication. [ABSTRACT FROM AUTHOR]

The minimally invasive coronary bypass operation is a procedure that has been firmly established in cardiac surgery for several years now. Only a few reports exist regarding the complications of this procedure. This case study reports on a 51-year-old man who collapsed 27 days after a left-sided internal mammary artery bypass on the anterior interventricular artery, when the bypass vessel ruptured. After pericardial puncture and cardiopulmonary resuscitation the patient was transported via air ambulance to a cardio-surgical center where he was successfully operated upon. [ABSTRACT FROM AUTHOR]
