Randomized Controlled Trial Clinical Trial
Satisfaction with epidural and intravenous patient-controlled analgesia.
Postoperative intravenous (i.v.) versus epidural morphine patient-controlled analgesia (PCA) were compared regarding maintenance of initial PCA route, pain levels, side effects, and levels of satisfaction. Additionally, the role of preoperative attitudinal expectations in predicting postoperative levels of satisfaction with pain management as well as maintenance of initial PCA route was evaluated. ⋯ Both techniques, i.v. and epidural PCA, result in high levels of satisfaction. Satisfaction with PCA can be accurately predicted in nearly three of four patients based on initial PCA route and preoperative attitudes. Additionally, maintaining the initial treatment plan can be accurately predicted based on age and preoperative attitudes. Patient expectations about pain relief should be addressed preoperatively, particularly with younger patients, for optimal results.

Randomized Controlled Trial Clinical Trial
Fear-avoidance behavior and anticipation of pain in patients with chronic low back pain: a randomized controlled study.
In a randomized controlled study, we investigated whether pain anticipation and fear-avoidance beliefs will lead to behavioral avoidance. ⋯ Results confirm that pain anticipation and fear-avoidance beliefs significantly influence the behavior of patients with low back pain in that they motivate avoidance behavior. Therapists must be aware of the powerful effects of cognitive processes, which can give rise to fear of pain and, consequently, avoidance behavior.

Evaluation of the age related prevalence of persistent low back pain has been estimated to be consistently higher in the elderly compared to the younger population. Facet joints have been shown to be the cause of chronic low back pain in 15% to 45% of the patients in controlled studies. Prevalence of facet joint mediated pain has not been studied in the elderly. ⋯ Facet joints were investigated with diagnostic blocks initially using lidocaine 1% followed by bupivacaine 0.25%, usually 2 weeks apart. The prevalence of facet joint mediated pain was determined to be 30% in the adults and 52% in the elderly, which was significantly higher with a false positive rate of 26% in adults and 33% in the elderly. In conclusion, the results of this study show that facet joint mediated pain is a significant problem in all patients suffering with chronic low back pain with the prevalence of 52% in the elderly and 30% in adults.

The cancer patient presents special challenges to the anesthesiologist. Cancer may have multiple effects including those due to the primary tumor, metastases, the effects and toxicity of cancer therapy, associated paraneoplastic and physiologic responses to the tumor and the strong psychological responses elicited by cancer. ⋯ Patient education and reassurance regarding issues of safety, pain control and respect for patient preferences are important goals as well. This review provides the anesthesiologist with both general and specific information important to the systematic and complete preoperative evaluation of the patient with cancer.

Pneumothoraces are classified as spontaneous, traumatic, and iatrogenic. Spontaneous pneumothoraces (SP) occur without recognized lung disease (primary, PSP) or due to an underlying lung disease (secondary, SSP). Treatment of PSP and SSP has been quite heterogeneous in the United States; adoption of the recently published American College of Chest Physicians guidelines will hopefully improve care. ⋯ Iatrogenic pneumothoraces appear most commonly due to transthoracic needle aspiration and may be treated in carefully selected patients with observation. The presence of underlying emphysema in the setting of an iatrogenic pneumothorax usually mandates placement of a drainage catheter. Newer mechanical ventilation modes and strategies may limit the development of positive pressure ventilation- related iatrogenic pneumothoraces.
