Ultrasound Mapping of Stimulated Finger Flexion During Infra-Clavicular Brachial Plexus Nerve Blockade for Elbow Arthroplasty and Its Correlation To Postoperative Analgesia

Background: Infraclavicular brachial plexus nerve blockade (ICNB) is a very common anesthetic procedure performed for upper extremity surgery at the elbow and distally, however the rate of adequate analgesia is variable among patients. Ultrasound guidance (US) has not been demonstrated to increase the success rate of ICNB when compared to nerve stimulator (NS) guidance. Combined US and NS guided ICNB have not been reported, although there is a call for more trials comparing the two techniques. This study was performed to observe if a specific anatomic region near the axillary artery of the brachial plexus identified by finger flexion with nerve stimulation results in improved postoperative analgesia. Method: Patients undergoing elective elbow arthroplasty received a postoperative ICNB. The angle of the nerve stimulator needle tip and the radial distance from the center of the arterial lumen at which an optimal finger flexion twitch response was observed were measured with ultrasound imaging. Pain scores and postoperative opioid dosages on discharge from the post anesthesia care unit and at 24 hours after surgery were recorded. Results: 11 patients enrolled in this study. Adequate finger flexion response to nerve stimulation that resulted in complete analgesia was more frequently observed when the needle was located in the postero-superior quadrant in relation to the axillary artery. Identifying a specific point near the brachial plexus in relation to the artery that consistently provides superior analgesia is desirable and would lead to improved analgesia and faster onset time of nerve blockade and would reduce the need for other approaches for brachial plexus blockade with their associated disadvantages.

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.
