Randomized Controlled Trial Comparative Study[Evaluation of CVC-set].
Frequently central venous catheter sets do not contain all necessary materials. To evaluate, if combined measures using a specially arranged central venous catheter (CVC) set result in economical and clinical advantages, we compared both cost and time differences of a CVC complete set with ECG guide wire lead and an adhesive fixation with a standard set requiring additional materials, ECG fluid column lead and surgical suture. Furthermore, quality of different ECG leads, the reliability and tolerability of the adhesive fixation was compared. ⋯ The test CVC complete set allows a significant time saving and cost reduction in performing a central venous catheter line because of completely included disposable materials. CVC position control via guide wire needs less time and shows significantly better quality of ECG compared to fluid column ECG lead. An adhesive revealed to be a reliable CVC fixation comparable to a surgical suture.

Randomized Controlled Trial[No potentiation of fentanyl by use of transdermal buprenorphine in patients undergoing fast-track anesthesia for open-heart surgery].
Simultaneous use of opioids with a different pharmacological profile may lead to unexpected prolongation of effects. In an open label study possible overhang in post-operative respiratory effects and vigilance was determined in a group of patients (n = 22) carrying a transdermal buprenorphine patch for at least 2 months for treatment of chronic pain, undergoing a fentanyl-based fast-track enflurane anesthetic technique for open-heart operation. Data was compared with another randomised group (n = 21) undergoing similar open-heart procedures with no other opioid than fentanyl on board. ⋯ Patients using a buprenorphine patch for the relief of chronic pain cannot be regarded as opioid naïve. Due to adaptive mechanisms and the development of tolerance, there is no prolongation of the respiratory depression induced by intraoperative fentanyl. Long-term use of transdermal buprenorphine does not lead to potentiation or prolongation of opioid effects in cardiac surgery patients.
