This consensus statement is directed to intensivists, hematologists, and oncologists caring for critically ill cancer patients and focuses on the management of these patients.

[Treatment strategy for an unstable chest wall after cardiopulmonary resuscitation]. / Versorgungsstrategie des instabilen Thorax nach kardiopulmonaler Reanimation.

Every year ca. 60,000 people in Germany undergo cardiopulmonary resuscitation (CPR). The two most frequent underlying causes are of cardiopulmonary and traumatic origin. According to the current CPR guidelines chest compressions should be performed in the middle of the sternum with a pressure frequency of 100-120/min and to a depth of 5-6 cm. In contrast to trauma patients where different injury patterns can arise depending on the accident mechanism, both the type of trauma and the injury pattern are similar in patients after CPR due to repetitive thorax compression. It is known that an early reconstruction of the thoracic wall and the restoration of the physiological breathing mechanics in trauma patients with unstable thoracic injuries reduce the rates of pneumonia and weaning failure and shorten the length of stay in the intensive care unit. As a result, it is increasingly being propagated that an unstable thoracic injury as a result of CPR should also be subjected to surgical treatment as soon as possible. In the hospital of the authors an algorithm was formulated based on clinical experience and the underlying evidence in a traumatological context and a surgical treatment strategy was designed, which is presented and discussed taking the available evidence into account.

Noninvasive Neurally Adjusted Ventilator Assist Ventilation in the Postoperative Period Produces Better Patient-Ventilator Synchrony but Not Comfort.

BACKGROUND: Noninvasive neurally adjusted ventilatory assist (NAVA) has been shown to improve patient-ventilator interaction in many settings. There is still scarce data with regard to postoperative patients indicated for noninvasive ventilation (NIV) which this study elates. The purpose of this trial was to evaluate postoperative patients for synchrony and comfort in noninvasive pressure support ventilation (NIV-PSV) vs. NIV-NAVA. METHODS: Twenty-two subjects received either NIV-NAVA or NIV-PSV in an object-blind, prospective, randomized, crossover fashion (observational trial). We evaluated blood gases and ventilator tracings throughout as well as comfort of ventilation at the end of each ventilation phase. RESULTS: There was an effective reduction in ventilator delays (p < 0.001) and negative pressure duration in NIV-NAVA as compared to NIV-PSV (p < 0.001). Although we used optimized settings in NIV-PSV, explaining the overall low incidence of asynchrony, NIV-NAVA led to reductions in the NeuroSync-index (p < 0.001) and all types of asynchrony except for double triggering that was significantly more frequent in NIV-NAVA vs. NIV-PSV (p = 0.02); ineffective efforts were reduced to zero by use of NIV-NAVA. In our population of previously lung-healthy subjects, we did not find differences in blood gases and patient comfort between the two modes. CONCLUSION: In the postoperative setting, NIV-NAVA is well suitable for use and effective in reducing asynchronies as well as a surrogate for work of breathing. Although increased synchrony was not transferred into an increased comfort, there was an advantage with regard to patient-ventilator interaction. The trial was registered at the German clinical Trials Register (DRKS no.: DRKS00005408).
