Lumbar plexus catheter

Karen Boretsky, Maria A Hernandez, Elizabeth Eastburn, Cornelius Sullivan
BACKGROUND: The clinical reliability and reproducibility of ultrasound-guided lumbar plexus blocks is not established in pediatric populations. We present the results of a combined nerve stimulation ultrasound-guided lumbar plexus block using the vertebral body, transverse process, and psoas muscle as landmarks on a transverse lumbar paravertebral sonogram with mid-axillary transducer placement, "shamrock method," in children and adolescents. AIMS: Our primary objective was to determine the rate of achieving sensory changes in the lumbar plexus distribution...

We describe the clinical presentation of a patient with spastic diplegia, and its unique perioperative challenges. Opioids and antispasmodic medications are the primary therapy for managing pain and spasticity in the perioperative setting. However, such combination results in several side-effects and their sedative properties are synergistic. A 64-year-old woman with a history of spastic diplegia and an intrathecal baclofen pump for the treatment of her lower extremity spasticity was scheduled for a third elective left knee arthroplasty...

BACKGROUND AND OBJECTIVES: Psoas blocks are an alternative to femoral nerve blocks and have the potential advantage of blocking the entire lumbar plexus. However, the psoas muscle is located deeply, making psoas blocks more difficult than femoral blocks. In contrast, while femoral blocks are generally easy to perform, the inguinal region is prone to infection. We thus tested the hypothesis that psoas blocks are associated with more insertion-related complications than femoral blocks but have fewer catheter-related infections...

PURPOSE: Significant post-operative pain occurs after hip arthroplasty. In a prior study, lumbar plexus nerve blocks provided comparable analgaesia to lumbar epidurals; however, multimodal analgaesics were not used consistently. METHODS: This study assessed a randomly selected cohort of 48 patients undergoing primary hip arthroplasty who received a regional anaesthesia technique for post-operative pain. Twenty-four patients with lumbar epidurals and 24 with single-injection lumbar plexus nerve blocks were reviewed using electronic medical records...

BACKGROUND AND OBJECTIVES: While benefits of regional anesthesia in total hip arthroplasty (THA) are well documented, data describing the incidence of complications related to the use of posterior lumbar plexus blockade for THA remain limited. Our primary aim was to evaluate the incidence of infectious, bleeding, and neurological complications related specifically to the use of continuous posterior lumbar plexus block for elective THA. METHODS: We reviewed the electronic medical records of all adult patients who underwent elective THA with continuous posterior lumbar plexus blockade between December 1, 2004, and April 30, 2015, using the Mayo Clinic Total Joint Registry...

BACKGROUND: Total hip arthroplasty (THA) is associated with significant postoperative pain. Both lumbar epidurals and lumbar plexus nerve blocks have been described for postoperative pain control, but it is unclear if one technique is more beneficial. METHODS: Using electronic medical records, a randomly selected, cohort of 58 patients with lumbar epidurals were compared with 58 patients with lumbar plexus nerve blocks following primary THA. The primary end point was 48-hour postoperative opiate consumption...

INTRODUCTION: Percutaneously inserted central venous catheters (epicutaneo-cava-catheter - ECC) are widely used in neonatal intensive care, facilitating the parenteral nutrition and the treatment of critically ill newborns. This invasive procedure is regarded as safe and associated with low complication rate. Possible life-threatening complications may result from malpositioning of ECC. Paraspinal misplacement of ECC is one of the most serious complications. CASE PRESENTATION: The authors report a case of misplacement of ECC inserted via left saphenous vein for intravenous feeding...

BACKGROUND AND OBJECTIVES: Inadvertent venous catheterizations occur in approximately 9% of lumbar epidural anesthetic procedures with catheter placement and, if not promptly recognized, can result in fatal consequences. The objective of this report is to describe a case of accidental catheterization of epidural venous plexus and its recording by computed tomography with contrast injection through the catheter. CASE REPORT: A female patient in her sixties, physical status II (ASA), underwent conventional cholecystectomy under balanced general anesthesia and an epidural with catheter for postoperative analgesia...

OBJECTIVE: To describe an ultrasound-guided approach for lumbar plexus catheter placement in dogs. STUDY DESIGN: Prospective experimental cadaveric study. ANIMALS: Eleven thawed canine cadavers (13 ± 2 kg). MATERIAL AND METHODS: A technique to place a catheter in the psoas compartment at the level of the lumbar plexus under ultrasound guidance was described. Ultrasonographic landmarks for the placement of a lumbar plexus catheter were identified as the body of the sixth lumbar vertebrae, the psoas muscle and the femoral nerve...

Intravascular, subdural, intrathecal, and subcutaneous placement of epidural catheters are known complications and common causes of anesthesia and analgesia failure. Because the epidural space is located near the retroperitoneum and catheters are placed blindly, it is possible that misplacement could involve other structures, including the inferior vena cava, the aorta, and the lumbar plexus. We report a case of an obese laterally positioned parturient who presented with an epidural catheter lodged in the retroperitoneum...

BACKGROUND: We herein provide an analysis of lumbar epidural catheterization, which outlines a detailed anatomical description of the epidural anatomy, and may improve the success rate of neuraxial cannulation. METHODS: Lumbar epidural catheters were placed in 50 adult embalmed cadavers. After catheterization, the lumbar dura and connecting structures between the epidural space and the vertebral body were separated. The positional relationship between the catheter and the posterior epidural space were observed and photographed...

The aim of this randomised, prospective, blinded study was to evaluate if stimulating catheters can decrease the minimum effective anaesthetic volume in 50% of patients during lumbar plexus block using mepivacaine 1.5% compared with standard catheters. Fifty-eight patients of ASA physical status 1-3 were randomly allocated to receive a lumbar plexus block via a stimulating or standard catheter, with 29 in each group. The first dose was 30 ml and subsequent doses were determined using the up-and-down staircase method...

Anaesthetists often stand in the front line to manage postpartum neurological deficits, although epidural analgesia is rarely responsible for these complications. An epidural analgesia was performed to relieve pain during spontaneous labor in a 34-year-old parturient. An emergency C-section was subsequently required due to fetal heart rate abnormalities. Twelve hours after catheter removal, the parturient developed a severe right leg motor and sensory neurological deficit, predominant on L5 and S1 roots and diagnosed by a neurologist as a central nerve root injury...

OBJECTIVE: To evaluate the initial results after the implementation of perioperative protocol in patients over 60 years of age undergoing surgical treatment for femur fractures. METHODS: We conducted a prospective study of patients older than 60 years who were hospitalized with femur fracture. They were operated under spinal anesthesia and analgesia by lumbar plexus blockade. Data evaluation was performed before arrival in the operating room during surgery, in the post-anesthesia recovery room and in the ward the next morning of the operation...

OBJECTIVE: Continuous lumbar plexus blocks provide excellent analgesia for total hip arthroplasty (THA), but their utility has been questioned as they may increase motor weakness. The aim of this study was to compare the efficacy of two different concentrations of ropivacaine on both postoperative analgesia and motor function. METHODS: Thirty patients were examined in this prospective, single center, double-blinded, parallel group, comparative, randomized controlled trial in patients undergoing primary THA...

OBJECTIVE: To compare the clinical effects of anesthesia and postoperative analgesia for patients with unilateral lower-extremity fracture between multiple injections through catheters beside the lumbar plexus or sciatic nerve and continuous epidural analgesia. METHODS: Seventy patients with unilateral lower-extremity fracture scheduled for internal fixation were randomly divided into group N (n = 35) and group E (n = 35). Patients in group N received combined lumbar plexus and sciatic nerve block, then a catheter was inserted into the psoas compartment or beside the sciatic nerve, according to the surgical site, and 25 mL 0...

BACKGROUND CONTEXT: Retrograde ejaculation (RE) is a complication of anterior lumbar interbody fusion (ALIF) techniques. Most commonly, this results from mechanical or inflammatory injury to the superior hypogastric plexus near the aortic bifurcation. Bone morphogenetic protein-2 (BMP-2) has been used in spinal fusions and has been associated with inflammatory and neuroinflammatory adverse reactions, which may contribute to RE development after anterior lumbar surgery. PURPOSE: While controlling for anterior approach technique, we compared the incidence of RE with and without rhBMP-2 exposure, in large, matched cohorts of patients after ALIF...

Properly placed central venous catheters have been effective in establishing prolonged access for total parenteral nutrition infusion in ill neonates. However, malposition of the catheter may lead to lethal complications. Malposition and infusion into the epidural venous plexus is most commonly diagnosed on the basis of radiographs and has been confirmed by lumbar puncture. Several studies describe catheter malposition and associated complications. None, however, demonstrate head ultrasound features. We present sonographic findings in a patient who received hyperalimentation for 15 days through a malpositioned lower extremity peripherally inserted central venous catheter...
