Peripheral nerve blocks (PNBs) of the lower extremities are effective techniques for anesthesia and postoperative pain control. So far, these techniques have been used less frequently than PNBs of the upper limb. Nevertheless, growing awareness of complications of neuroaxial techniques, improved equipment and modern techniques for nerve localization have led to an increased use of PNBs of the lower limb. ⋯ They should also know the typical complications and side-effects and thoroughly inform patients about such potential problems. Continuous PNBs (perineural catheters) allow the benefits of PNBs to be prolonged into the postoperative period. Compared to continuous neuroaxial techniques continuous PNBs are equally effective for pain control but seem to be associated with fewer complications and side-effects.

In patient care several clinical departments are often involved in the treatment of a single case. Due to this shared work and internal patient transfer between departments the respective departments have to share the single reimbursement sum which is granted for each hospital case in the German DRG system. The intensive care unit in particular, at least if maintained as an independent department, has a high rate of internal transfers and most of the patients will be transferred back to the original department prior to discharge from hospital. ⋯ Three different methods of supplemental revenues allocation were analyzed regarding the financial impact on the intensive care unit: allocation to the department from which the patient is discharged, allocation according to the length of stay in a particular department (in this case the intensive care unit) and allocation based on actually documented medical services eligible for supplemental revenues. The supplemental revenues take up a considerable share of the total reimbursement for intensive care. Based on the first 2 allocation methods the intensive care unit would receive 20% less supplemental revenues compared to the third allocation method, which supposedly reflects best the actual costs.

In this study the impact of 25 mg of ketamine racemate given just before surgery on recovery times and postoperative analgesic needs in patients undergoing vaginal hysterectomy and receiving propofol-remifentanil anaesthesia was investigated. ⋯ This study demonstrated that 25 mg ketamine racemate given just before surgery significantly prolongs recovery times without reducing post-operative analgesic needs when applied to patients undergoing vaginal hysterectomy and receiving propofol-remifentanil anaesthesia. A bolus dose of 25 mg ketamine racemate cannot therefore be recommended for preemptive analgesia under these conditions.
