Randomized Controlled Trial Comparative Study
[Reduction in no flow time using a laryngeal tube: comparison to bag-mask ventilation].
In 2005 the European Resuscitation Council (ERC) published the new guidelines for Advanced Life Support (ALS). One of the aims was to reduce the no flow time (NFT), without chest compression in the first period of cardiac arrest. Furthermore the guidelines recommend that endotracheal intubation should only be carried out by personnel experienced in this procedure. ⋯ The use of the LTS-D on a manikin by emergency physicians after standardised cardiac arrest training significantly reduces the NFT in comparison to BMV. Therefore the LTS-D seems to be a good alternative to BMV during a simulated cardiac arrest scenario.

Randomized Controlled Trial
[Antibiotic treatment of surgical intensive care patients: procalcitonin to guide duration of therapy].
The development of resistance by infective bacterial species is an incentive to reconsider the indications and administration of available antibiotics. Correct recognition of the indications and duration of therapy are particularly important for the use of highly potent substances in the intensive care situation. There has as yet been no clinical chemical parameter which is capable of specifically distinguishing a bacterial infection from a viral or non-infectious inflammatory reaction, but it now appears that procalcitonin (PCT) offers this possibility. ⋯ The control group consisted of 53 patients with a standardized duration of antibiotic therapy over 8 days. Demographic and clinical data were comparable in both groups. However, in the PCT group the duration of antibiotic therapy was significantly shorter compared to controls (5.9+/-1.7 vs. 7.9+/-0.5 days, p<0.001) without unfavorable effects on clinical outcome.

Randomized Controlled Trial Multicenter Study
Levobupivacaine for epidural anaesthesia and postoperative analgesia in hip surgery: a multi-center efficacy and safety equivalence study with bupivacaine and ropivacaine.
The aim of this randomized, single blind phase IIIb study was to evaluate the efficacy of 0.5% levobupivacaine versus 0.5% bupivacaine and 0.75% ropivacaine administered as epidural anesthesia and 0.125% levobupivacaine versus 0.125% bupivacaine and 0.2% ropivacaine for postoperative analgesia. The study was designed to test the equivalence of the overall profile of levobupivacaine against bupivacaine and ropivacaine. In addition, parameters of clinical safety were assessed. ⋯ The efficacy of epidural levobupivacaine for hip surgery and postoperative analgesia is equivalent and shows a comparable clinical profile to bupivacaine and 50-60% higher concentrated ropivacaine. The results of this equivalence study confirm suggestions derived from previous comparative studies.

Randomized Controlled Trial
[Sympathomimetic effects of low-dose S(+)-ketamine. Effect of propofol dosage].
In analgetic dosages ketamine has stimulatory effects on the cardiovascular system, which limits its use in patients with heart disease. The aim of this study was to clarify whether low-dose S(+)-ketamine used to prevent chronic pain similarly stimulates the cardiovascular system and to determine the impact of propofol dosage on this effect. ⋯ Even low-dose S(+)-ketamine has a stimulatory effect on the cardiovascular system. This stimulatory effect is nullified in the presence of a continuous propofol infusion at a dosage of more than 3 mg/kg BW/h.

Randomized Controlled Trial
[Intrathecal morphine in orthopaedic surgery patients. Optimised dose in patients receiving dipyrone].
The influence of different postoperative doses of intrathecal morphine on the time of first opioid request by orthopaedic patients was investigated. The first choice analgesic was dipyrone and a maximum dose of 6 mg/day was allowed. ⋯ In orthopaedic patients with dipyrone as the primary analgesic, the addition of 0.1 mg or 0.2 mg morphine to spinal anaesthesia provided a simple long-lasting postoperative analgesia and the use of additional opioids could be avoided during the 24h postoperative period.
