ReviewRegional anesthesia techniques for pain control in the intensive care unit.
The judicious use of regional anesthesia in the intensive care unit should improve patient comfort. Techniques covered include intercostal nerve blocks, interpleural blocks, paravertebral blocks, brachial plexus blocks, and femoral nerve blocks. Rational patient selection for each technique mentioned is also discussed.

Four thesis related to economics of intensive care medicine are derived from an analysis of the intensive care unit of the university hospital of Basel, Switzerland, and the respective literature: (1) Intensive care medicine is costly but rationing can be avoided by rationalization. (2) Exemption or withdrawal of intensive care cannot be justified in the absence of accurate predictors of costs and outcomes of individual patients. (3) Intensive care physicians must not act as judges but on behalf of patients incapable of decision making. They must represent patients' interests vis-à-vis authorities and reimbursing institutions. (4) Analyses of cost-efficiency are instrumental for process improvement of intensive care, for negotiations on reimbursement and for the regulatory decisions of the authorities. Tools for economic analyses of intensive care medicine are therefore worthy of further development.

Case Reports Comparative StudyMonitoring by subcutaneous microdialysis in neurosurgical intensive care.
Microdialysis is an in vivo sampling technique which provides a powerful approach to monitoring metabolic events. We have performed a study to determine the feasibility and effectiveness of subcutaneous microdialysis in monitoring patients on the Neurosurgical Intensive Care Unit (NICU). A microdialysis probe was placed in the subcutaneous fat of the anterior abdominal wall and perfused with Ringer's solution. ⋯ In one patient, following an apparently brief period of hypoxia, there was a prolonged disturbance of tissue chemistry. Another patient with obesity had significantly higher concentrations of dialysate glucose, lactate and glutamate. Monitoring by subcutaneous microdialysis on intensive care units is feasible, reveals unexpected changes in tissue metabolism and might be an important adjunct for the interpretation of intracerebral data.

Case ReportsContinuous EEG monitoring in the intensive care unit: early findings and clinical efficacy.
The assessment of the neurocritical care patient involves serial assessment of neurologic status using bedside clinical examination and a variety of periodic neurophysiologic testing. Continuous electroencephalographic (CEEG) monitoring in the intensive care unit offers a unique means to track neurologic function directly and regionally. CEEG is becoming more widespread with a growing but small body of literature. ⋯ The basic tenets of establishing clinical effectiveness for CEEG in the ICU are discussed while acknowledging a need for further study of clinical effectiveness. We review our initial clinical experience of CEEG in 300 patients and outline the clinical efficacy in terms of cost reduction and improvement in outcome (P < 0.01) using CEEG. Finally, several controversial aspects of CEEG are enumerated, and the need for additional study to answer these pressing questions is presented.
