Differences in analgesia in opioid naïve and tolerant patients with sciatic nerve blockade following elective foot and ankle surgery

1.1 Introduction and Purpose: Adequate postoperative analgesia in the opioid tolerant with chronic non-malignant pain is challenging. Multimodal pain relief regimens include regional anesthesia but opioid tolerant patients report increased postoperative pain and opioid consumption. This study compared analgesia in opioid naïve and tolerant patients receiving postoperative sciatic nerve blockade for foot and ankle surgery. 1.2 Method: Preoperative pain scores, trauma, maintenance and intraoperative opioid doses and following postoperative sciatic nerve blockade, patient self-reported pain scores and opioid consumption at discharge from the post-anesthesia unit and 24 hours were recorded. 1.3 Results: 191 patients enrolled. 40.3% were opioid tolerant and 33% had lower extremity trauma. Preoperative, immediate and delayed postoperative pain scores and intraoperative, immediate and 24 hour postoperative consumption of opioids were increased in opioid tolerant patients. Trauma and continuous infusion in opioid naïve and tolerant groups did not result in differences in 24 hour opioid consumption. 1.4 Limitations: Small subgroups and use of the pain score limited the accuracy of results. 1.5 Conclusion: Opioid tolerant patients require greater analgesic doses following sciatic nerve blockade for foot and ankle surgery. 24 hour opioid consumption for opioid naïve and tolerant patients is neither influenced by lower extremity injury nor continuous infusion.

Prolonged Duration of Sciatic Nerve Blockade in the Elderly after Foot and Ankle Surgery

1.1 Background and Objectives: Perioperative morbidity related to anesthesia renders elderly patients vulnerable because age related factors affect medication effects, clearance and metabolism. Regional anesthesia within a multimodal regimen reduces opioid adverse effects in the elderly and improves immediate analgesia but not long term recovery and prolonged nerve blockade has been reported. The purpose of this study was to assess analgesic effects of sciatic nerve blockade in the elderly. 1.2 Methods: Postoperative sciatic nerve blockade was administered for foot and ankle surgery to patients over age 18 years. Preoperative, post-anesthesia unit and 24 hour postoperative pain scores and opioid doses for these same intervals were recorded. 1.3 Results: 47 patients enrolled and 12 (25.5%) were over age 70. Preoperative, immediate and 24 post-operative pain scores and total intraoperative and immediate postoperative opioid doses were lower in the elderly. The total 24 hour postoperative opioid doses in the elderly were lower compared to the younger group. 1.4 Conclusions: Total 24 hour postoperative cumulative opioid doses after sciatic nerve blockade in patients over 70 are lower than in younger patients. Further observations in greater numbers of patients and improved ultrasound to assess sciatic nerve structure in the elderly are warranted to study this effect.

Abstract Title: Ultrasound Guided Trans-sartorial Continuous Saphenous Nerve Blockade - A technique for Relief of Postoperative Medial Incisional Foot and Ankle Pain

The saphenous nerve (SaN) innervates the region from the upper medial thigh to the medial aspect of the foot and ankle. A femoral nerve block (FNB) is effective for blockade of the SaN but this causes quadriceps weekness and reduced patient mobility that is unsuitable in an ambulatory surgical setting.

Tumor progression in hepatocellular carcinoma: Relationship with tumor stroma and parenchymal disease

Background: Encapsulation in hepatocellular carcinoma is associated with decreased invasiveness and improved survival in several series. Although active fibrogenesis by myofibroblasts has been demonstrated in the capsule, it is unclear if the capsule results from a general increase in peritumoral fibrosis, or an inherently less invasive tumor phenotype. The relationship between collagen deposition within tumor stroma, presence of cirrhosis and invasiveness also needs clarification. Methods: We performed immunohistochemistry for collagens I, III, IV and VI on sections of encapsulated and non-encapsulated hepatocellular carcinoma, arising in cirrhotic and non-cirrhotic livers. Staining was graded semi-quantitatively in tumor stromal elements and adjacent parenchymal sinusoids. The relationship of this staining with encapsulation, cirrhosis, and vascular invasion was analyzed. Results: Formation of a discrete capsular layer was associated with reduced vascular invasion, but not with a pervasive increase in peritumoral fibrosis. Increased collagen I content of tumor stroma and adjacent parenchymal sinusoids was associated with non-encapsulated tumors and vascular invasion. The presence of cirrhosis had little effect on capsule composition. Conclusions: Encapsulation of hepatocellular carcinoma reflects reduced invasiveness, rather than increased peritumoral collagen synthesis, which may instead enhance invasion. Increased intratumoral collagen I protein is also associated with increased tumor invasiveness. Pre-existing cirrhosis has little effect on tumor progression, possibly because the characteristics of cirrhosis are overwhelmed by tumor-induced changes in the adjacent parenchyma.(C) 2003 Blackwell Publishing Asia Pty Ltd.

Homocysteine and cardiovascular disease in renal disease

Elevated homocysteine (hyperhomocysteinaemia) in renal patients is a major concern for physicians. Although cause and effect between homocysteine and cardiovascular disease (CVD) has not been established in either the general population or renal patients, there is much evidence that this relationship does exist. Purported mechanisms that may explain this effect include increases in endothelial injury, smooth muscle cell proliferation, low-density lipoprotein oxidation and changes in haemostatic balance. Renal patients have a much greater incidence of hyperhomocysteinaemia and this may be explained by decreases in either the renal or extrarenal metabolism of the compound. We conclude that data from long-term placebo-controlled trials are urgently required to determine whether hyperhomocysteinaemia in renal patients is a cause of CVD events and requires therapeutic targeting.
