Thoracic Epidural Anesthesia and the Patient with Heart Disease: Benefits, Risks, and Controversies

Pain scores are not predictive of pain medication utilization

Objective. To compare Visual Analogue Scale (VAS) scores with overall postoperative pain medication requirements including cumulative dose and patterns of medication utilization and to determine whether VAS scores predict pain medication utilization. Methods. VAS scores and pain medication data were collected from participants in a randomized trial of the utility of phenazopyridine for improved pain control following gynecologic surgery. Results. The mean age of the 219 participants was 54 (range19 to 94). We did not detect any association between VAS and pain medication utilization for patient-controlled anesthesia (PCA) or RN administered (intravenous or oral) medications. We also did not detect any association between the number of VAS scores recorded and mean pain scores. Conclusion. Postoperative VAS scores do not predict pain medication use in catheterized women inpatients following gynecologic surgery. Increased pain severity, as reflected by higher VAS scores, is not associated with an increase in pain assessment. Our findings suggest that VAS scores are of limited utility for optimal pain control. Alternative or complimentary methods may improve pain management.

Perioperative pain management in patients undergoing thoracic surgery

Adequate perioperative pain management has become an important part of thoracic anaesthesia. In the past few years, many trials have been performed to evaluate the efficacy of various analgesic regimens. This review summarizes the most frequently used analgesic techniques, with a particular emphasis on the results of studies and innovative ideas published between August 1999 and August 2000.

Regional anaesthesia in patients at coronary risk for noncardiac and cardiac surgery

This review presents a brief overview about the role of regional anaesthesia in patients at risk for myocardial ischemia and/or infarction after cardiac and noncardiac surgical procedures. It includes pathophysiological insights in the problems of plaque rupture and the possible interactions by the use of regional anaesthesia. Special emphasis is put on the subject of thoracic epidural anaesthesia with newer studies showing improvement in relief of angina and improvement of global systolic and diastolic function in patients with coronary artery disease.
