Objectives
The primary objective of this study was to determine the feasibility of ultrasound-guided femoral nerve blocks in elderly patients with hip fractures in the emergency department (ED). The secondary objective was to examine the effectiveness of this technique as an adjunct for pain control in the ED.Methods
This prospective observational study enrolled a convenience sample of 13 patients with hip fractures. Ultrasound-guided femoral nerve block was performed on all participants. To determine feasibility, time to perform the procedure, number of attempts, and complications were measured. To determine effectiveness of pain control, numerical rating scores were assessed at baseline and at 15 minutes, 30 minutes, and hourly after the procedure for 4 hours. Summary statistics were calculated for feasibility measures. Wilcoxon matched-pairs signed-rank tests and Friedman analysis of variance test were used to compare differences in pain scores.Results
The median age of the participants was 82 years (range, 67-94 years); 9 were female. The median time to perform the procedure was 8 minutes (range, 7-11 minutes). All procedures required only one attempt; there were no complications. After the procedure, there were 44% and 67% relative decreases in pain scores at 15 minutes (P ≤ .002) and at 30 minutes (P ≤ .001), respectively. Pain scores were unchanged from 30 minutes to 4 hours after the procedure (P ≤ .77).Conclusions
Ultrasound-guided femoral nerve blocks are feasible to perform in the ED. Significant and sustained decreases in pain scores were achieved with this technique. 相似文献4.

In patients presenting with atraumatic joint pain and swelling, diagnosis is typically made by synovial fluid analysis. Management of an acute suspected hip joint arthritis can present a challenge to the emergency physician (EP). Hip joint effusions are somewhat more difficult to identify and aspirate than effusions in other joints that are commonly managed by EPs. Identification and aspiration of a hip joint effusion under ultrasound guidance is a well-established procedure in the fields of orthopedic surgery and interventional radiology. Here, we report 4 cases of ultrasound-guided hip arthrocentesis at the bedside by EPs; relevant technical details of the procedure are reviewed. These cases demonstrate the feasibility of ultrasound-guided hip arthrocentesis in the emergency department (ED) by EPs. With increasing availability of bedside ultrasound in the ED, suspected hip joint arthritis or infection may be evaluated and managed by the trained EP in a fashion similar to other joint arthritides. 相似文献

BACKGROUND:
Abdominal wall hematoma is due to trauma, coagulation disorders or anticoagulation therapy complications.METHODS:
In this report we present a case of a 44-year-old female who suffered from blunt abdominal trauma and presented to the emergency department with sharp abdominal pain and ecchymosis. FAST and abdominal computerized tomography (CT) revealed an abdominal wall hematoma. Treatment with an ultrasound-guided percutaneous drainage was performed successfully.RESULTS:
The patient remained under observation for six hours with serial ultrasound scans, and no signs of hematoma recurrence were present. She was discharged the same day with clinical improvement.CONCLUSION:
Complete history investigation and clinical examination help to make a correct diagnosis of abdominal wall hematoma, select a prompt treatment, and reduce complications.KEY WORDS: Rectus sheath hematoma, Abdominal wall hematoma, Emergency Department, FAST, Ultrasound guided percutaneous drainage 相似文献7.
Each year, over 300,000 individuals aged 65 and older are hospitalized for hip fractures in the United States.1 Traditional pain management in the elderly population is difficult because of physiologic changes and comorbidities.2 Peripheral nerve blocks are often placed by anesthesia professionals following hip surgery as part of a multi modal pain management program. Recently, the placement of fascia iliacal blocks has been successfully utilized in the emergency department for geriatric patients suffering from hip fractures. This technique can be easily mastered with proper training for use in the emergency department and pre-hospital environments reducing the pain of hip fracture and its associated risks of morbidity. This article provides a detailed review of anatomy and an ultrasound-guided technique for placement of the fascia iliaca block. 相似文献

Shoulder dislocations are often associated with significant pain, and many emergency physicians choose conscious sedation to achieve reduction. Concerns about oxygenation, airway protection, and aspiration may make some patients poor candidates for conscious sedation. Ideally, complete pain control and muscle relaxation could be achieved without airway compromise. Interscalene nerve blocks are routinely used for shoulder surgery in the operating suite. The equipment required to locate the nerve plexus blindly is typically not available in the ED setting. Recent work has shown that ultrasound guidance is ideal for the interscalene block and would make it possible in the ED. We present 4 cases of patients receiving ultrasound-guided interscalene blocks for pain control and muscle relaxation during shoulder reduction. Complete pain control, muscle relaxation, and joint reduction were achieved in each case. 相似文献

Peripheral nerve blockade (PNB) for orthopedic surgery is usually performed without visual guidance, relying mainly on surface
anatomic landmarks and electrical stimulation to localize nerves. Moreover, multiple trial and error attempts to place a needle
can frustrate the operator, cause unwarranted pain to the patient, and waste valuable time in the operating room. Inaccurate
needle placement and spread of local anesthetic account for most PNB failures, whereas “trial and error” needle manipulations
for nerve localization can cause complications. The recent application of ultrasound (US) to PNB affords real-time imaging
of the target nerve, needle, and surrounding vasculature, such that needle proximity to the nerve is ensured and vascular
puncture avoided. This article reviews the advantages, principles, and techniques of US for the most common types of PNB. 相似文献

Wounds and injuries to hands are common presentations to emergency departments. Traditionally wounds would be treated by infiltration of the wound with a local anaesthetic. This has the disadvantage of distorting the wound edges and making it difficult to oppose the wound edges.If a wound or an injury involves many different parts of the hand multiple infiltration points may be required to ensure adequate pain relief to enable treatment to occur.By using a regional block of the wrist the whole 相似文献

A continuous peripheral nerve block—also termed “perineural local anesthetic infusion”—involves the percutaneous insertion of a catheter adjacent to a peripheral nerve, followed by local anesthetic administration via the catheter, providing anesthesia/analgesia for a prolonged period of time. The most-common indication for continuous peripheral nerve blocks is analgesia following painful surgical procedures; but, they are also used for inducing a sympathectomy and vasodilation following digit transfer/replantation, a vascular accident, limb salvage, or peripheral embolism; treating intractable hiccups; alleviating the vasospasm of Raynaud’s disease; and treating chronic pain such as phantom limb pain, cancer-induced pain, complex regional pain syndrome, and trigeminal neuralgia. Continuous peripheral nerve blocks may also provide pain control during medical transport, or awaiting surgical correction. The most common catheter insertion techniques include electrical stimulation and ultrasound-guidance. Long-acting local anesthetic is usually the sole infusate, and is optimally delivered with a continuous basal infusion with available patient-controlled bolus doses. Benefits are dependent upon analgesia improvement, and include decreasing pain, supplemental analgesic consumption, opioid-related side effects, sleep disturbances, patient dissatisfaction, time until discharge readiness, and actual hospitalization duration. Additional possible benefits include improvements in ambulation/functioning and an accelerated resumption of passive joint range-of-motion. Most benefits occur during the infusion itself, but a few studies suggest prolonged benefits following catheter removal in some cases. Minor complications occur at approximately the incidence as for single-injection peripheral nerve blocks; but, major risks including nerve injury are extraordinary uncommon. 相似文献

Sophisticated regional anesthesia techniques have experienced substantial growth throughout the past 5 years for acute and
chronic pain management. The recognition that regional anesthesia leads to superior postoperative outcomes in acute pain management
and to an increased understanding of the pathogenesis of chronic pain has led to increased use of continuous peripheral nerve
catheters. Furthermore, the availability of new equipment and techniques specifically designed to facilitate effective catheter
placement has increased interest and adoption of peripheral nerve catheters to manage painful conditions. This has become
particularly relevant as the scope of ambulatory surgery continues to grow. To maximize success rates with continuous peripheral
nerve catheters, clinicians must be intimately aware of the pertinent regional anatomy and technical issues surrounding placement
and maintenance of continuous nerve blockade. The recent development of outpatient infusion systems and novel anesthetics
has been exciting and is likely to lead to an increase in the use of continuous peripheral catheter techniques. The consistent
recognition that these techniques dramatically increase patient satisfaction should dictate an increasing presence in the
field of pain management throughout the next several years. 相似文献

Endometriosis of the abdominal wall typically occurs as a painful mass in a lower abdominal incision from previous cesarean section or hysterectomy. Most patients are young and in their active reproductive years. The histologic diagnosis requires a combination of either endometrial-like glands, endometrial stroma, or hemosiderin pigment. The diagnosis must be considered in any woman with an abdominal wall mass and a history of transabdominal gynecologic surgery. Wide excision offers the best chance to prevent recurrence. 相似文献
