Clinical TrialRight ventricular function in early septic shock states.
To define a variable which could reliably predict when fluid resuscitation as monotherapy is not expected to improve organ perfusion pressure, owing to limitations in cardiac output responsiveness in patients with severe sepsis. ⋯ In 27 septic shock patients investigated, we diagnosed right ventricular dysfunction in 41%. In this specific patient population fluid replacement alone did not succeed in stabilizing hemodynamic variables, therefore necessitating catecholamine therapy.

The growing number of technical devices in ICUs makes noise exposure a major stressor. The purpose of this study was to assess noise levels during routine operation in our ICU. ⋯ During the day and at night SPL always surpasses the permissible noise exposure for 24 h of 45 db(A) recommended by the US Environmental Protection Agency. Alarms cause the most irritating noise. Hospital management should pay attention to internal noise, and SPL should be measured routinely.

Retracted PublicationDoes platelet size correlate with function in patients undergoing cardiac surgery?
Platelet dysfunction secondary to cardiopulmonary bypass (CPB) is one of the major reasons for nonsurgical post-operative bleeding in cardiac surgery. Whether platelet size is an indicator for platelet function was investigated in patients undergoing coronary artery bypass grafting. ⋯ Platelet volume is easy to measure even in the operation room or in ICU and may indicate abnormalities in platelet function in the post-bypass period of cardiac surgery patients.
