Randomized Controlled Trial
[Intra-articular bupivacaine following hip joint arthroscopy. Effect on postoperative pain].
The effect of intra-articular bupivacaine on postoperative pain following arthroscopy has been intensively studied for the knee joint but no data are currently available for the hip joint. The aim of the present prospective, randomized and double-blind study was to evaluate a possible effect of intra-articular bupivacaine on postoperative pain intensity following hip arthroscopy. A total of 26 patients were included: 13 received 20 ml of 0.25% bupivacaine through the trocar at the end of surgery and 13 patients received 20 ml of 0.9% NaCl as placebo. ⋯ In the bupivacaine group, a significantly lower mean VAS was recorded at rest (17.5 vs 27.5, p=0.05) and during movement of the hip joint (23 vs. 46, p=0.001). The additional piritramide consumption tended to be higher in the placebo group. In conclusion, intra-articular bupivacaine following arthroscopic hip surgery reduces pain in the postoperative period mainly during movement and thus may possibly allow earlier mobilization.

Acute renal failure is a common complication in intensive care medicine. While the incidence of acute renal failure increases, mortality still remains at a high level. In Europe continuous renal replacement therapy (CRRT) has become the standard treatment for acute renal failure. ⋯ A new approach in renal replacement therapy is the slow extended daily dialysis (SLEDD), which combines the advantages of CRRT and IHD. First results are promising, but further investigations are needed to show whether outcome can be improved. A final evidence-based recommendation on the dosing of CRRT or a definitive answer to the question whether daily IHD is better than CRRT, can probably only be possible after two running multicentre studies, the VA/NIH Acute Renal Failure Trial Network (ATN) study and the Augmented Versus Normal Renal Replacement Therapy in Severe Acute Renal Failure Study (ANZICS 2005) Australia and New Zealand Intensive Care Group.

There are no consensus guidelines for the management of postoperative nausea and vomiting (PONV) in German speaking countries. This meeting was intended to develop such guidelines on which individual health care facilities can derive their specific standard operating procedures (SOPs). Anesthesiologists reviewed published literature on key topics which were subsequently discussed during two meetings. ⋯ Therapeutic interventions of PONV should be administered promptly using an antiemetic which has not been used before. The group suggests algorithms where prophylactic interventions are mainly dependent on the patient's risk for PONV. These algorithms should provide evidence-based guidelines allowing the development of SOPs/policies which take local circumstances into account.

Advanced Trauma Life Support (ATLS) is a concept for rapid initial assessment and primary management of an injured patient, starting at the time of injury and continuing through initial assessment, lifesaving interventions, re-evaluation, stabilization and, when needed, transfer to a trauma centre. Despite some shortcomings, it is the only standardized concept for emergency room management, which is internationally accepted. Because of its simple and clear structure, it is flexible and can be universally integrated into existing emergency room algorithms under consideration of local, regional as well as national and international peculiarities in the sense of a "common language of trauma". Under these aspects ATLS also seems to be a valid concept for Europe.

[Intra-articular ketamine after arthroscopic knee surgery. Optimisation of postoperative analgesia].
Surgery of the knee can be very painful and sufficient postoperative pain treatment is often problematic. To optimize postoperative analgesia, application of local analgesics has been suggested. In the present study it was investigated whether intra-articular administration of ketamine reduces the level of pain after arthroscopic knee surgery. ⋯ The i.a. application of ketamine after arthroscopic knee surgery leads to a significant decrease of postoperative analgesic demand and decreases patients' subjective level of pain compared to i.a. application of bupivacaine or placebo. Likewise, the i.v. application of ketamine is similarly effective but the effect is of shorter duration.
