Catheter nerve analgesia

Brian M Ilfeld
A continuous peripheral nerve block (CPNB) consists of a percutaneously inserted catheter with its tip adjacent to a target nerve/plexus through which local anesthetic may be administered, providing a prolonged block that may be titrated to the desired effect. In the decades after its first report in 1946, a plethora of data relating to CPNB was published, much of which was examined in a 2011 Anesthesia & Analgesia article. The current update is an evidence-based review of the CPNB literature published in the interim...

BACKGROUND: Multimodal pain management strategies are used for analgesia following pectus excavatum repair. However, the optimal regimen has not been identified. We describe our early experience with intercostal cryoablation for pain management in children undergoing the Nuss procedure and compare early cryoablation outcomes to our prior outcomes using thoracic epidural analgesia. METHODS: A multi-institutional, retrospective review of fifty-two patients undergoing Nuss bar placement with either intercostal cryoablation (n=26) or thoracic epidural analgesia (n=26) from March 2013 to January 2016 was conducted...

We compared the effect of two different positions of a sciatic nerve catheter within the popliteal fossa on local anaesthetic consumption and postoperative analgesia in patients undergoing day-case hallux valgus repair. Eighty-four patients were randomly allocated to receive a sciatic nerve catheter either between the tibial and peroneal components (sciatic group) or medial to the tibial nerve (tibial group). The primary endpoint was postoperative local anaesthetic consumption, while secondary endpoints were pain scores, number of occasions where sleep was disturbed by pain and incidence of insensate limb and foot drop at 24 h and 48 h postoperatively...

BACKGROUND: Despite the benefits of continuous peripheral nerve blocks, catheter dislodgment remains a major problem, especially in the ambulatory setting. However, catheter dressing techniques to prevent such dislodgment have not been studied rigorously. We designed this simulation study to test the strength of two commercially available catheter dressings. METHODS: Using a cadaver model, we randomly assigned 20 trials to one of two dressing techniques applied to the lateral thigh: 1) clear adhesive dressing alone, or 2) clear adhesive dressing with an anchoring device...

BACKGROUND: Management of postoperative pain often requires multimodal approaches. Suboptimal dosages of current therapies can leave patients experiencing periods of insufficient analgesia, often requiring rescue therapy. With absence of a validated and standardized approach to pain management, further refinement of treatment protocols and targeted therapeutics is needed. Liposomal bupivacaine (Exparel) is a longer acting form of traditional bupivacaine that delivers the drug by means of a multivesicular liposomal system...

BACKGROUND: The shoulder area is mainly innervated with the C5 and C6 nerve roots, and interscalene brachial plexus block (ISB) is widely used for postoperative analgesia after shoulder surgery. However, it is associated with adverse effects, such as numbness and weakness in the blocked arm due to an unwanted block of the lower brachial plexus (C7-T1). We hypothesized that the C5 approach during ISB would provide postoperative analgesia while minimizing adverse events after arthroscopic shoulder surgery...

BACKGROUND: The existence of peripheral opioid receptors and its effectiveness in peripheral nerve block remain controversial. The aim of this prospective, randomized, double-blinded study was to examine the analgesic effects of adding fentanyl to ropivacaine for continuous femoral nerve block (CFNB) using patient-controlled analgesia after total knee arthroplasty (TKA). METHODS: The patients were divided into 2 groups, each with n = 40 in ropivacaine (R) group and n = 42 in R with fentanyl (R + F) group...

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...

We report a novel case of a patient undergoing a bilateral shoulder hemiarthroplasty for chronic bilateral shoulder dislocations with proximal humeral fractures. Bilateral selective suprascapular nerve catheters were placed preoperatively with the intent to provide continuous local anesthetic-based analgesia while sparing diaphragmatic function. Postoperative respiratory mechanics were relatively spared while numerical rating scale pain scores were suggestive of analgesic benefit.

BACKGROUND: Pectus excavatum (PE) is the most common congenital chest wall deformity, occurring in 1 : 1000 children with a male to female ratio of 4 : 1. Several procedures have been described to manage this deformity, including cartilage resection with sternal osteotomy (the Ravitch procedure) and a minimally invasive repair technique (the Nuss procedure). While initially described as a nonthoracoscopic technique, the current surgical approach of the Royal Childrens Hospital involves thoracoscopic assistance...

BACKGROUND: Both neuraxial and peripheral regional analgesic techniques offer postoperative analgesia for total hip arthroplasty (THA) patients. While no single technique is preferred, quadriceps muscle weakness from peripheral nerve blocks may impede rehabilitation. We designed this study to compare postoperative ambulation outcome in THA patients who were treated with a new ultrasound-guided fascia iliaca catheter (FIC) technique or intrathecal morphine (ITM). METHODS: We reviewed the electronic health records of a sequential series of primary unilateral THA patients who were part of a standardized clinical pathway; apart from differences in regional analgesic technique, all other aspects of the pathway were the same...

A 53-year-old woman with extreme obesity (body mass index = 82 kg/m) presented for an open reduction and internal fixation of the proximal humerus. This report describes the novel management of her continuous brachial plexus catheter in the setting of her comorbidities. Phrenic nerve paralysis from brachial plexus blocks can cause clinically significant dyspnea in obese patients. Brachial plexus catheters can be used effectively for these patients with some modification to routine management. We detail our use of a short-acting chloroprocaine test dose for phrenic paralysis and demand-only dosing to provide effective analgesia while avoiding respiratory complications associated with these blocks...

BACKGROUND: Children with microtia complain of severe postoperative pain during early postoperative days after rib cartilage harvest for auricular reconstruction. The purpose of this study was to evaluate the effects of preventive donor site wound analgesia by intercostal nerve block (ICNB) and catheter-based infusion of local analgesics on postoperative pain after rib cartilage graft for auricular reconstruction in children with microtia. METHODS: In this prospective randomized study, 66 children underwent postoperative pain control using either preventive ICNB followed by catheter-based infusion (33 patients, study group) or intravenous (IV) analgesia alone (33 patients, control group)...

Pain is a major concern for patients suffering from cancer. Although opioid drugs remain the gold standard for treatment of pain, little is known about the interest of continuous analgesia techniques as alternative. The aim of the present article is to detail the feasibility and to present the diversity of continuous perineural infusion of local anesthetic. A series of five patients suffering from different cancer-related pain is presented. A continuous perineural block was proposed to patients presenting with unbearable pain in an area innervated by a plexus or a nerve despite parenteral analgesic pharmacotherapy...

PURPOSE: Extraoral mandibular nerve block (MNB) is used in oropharyngeal surgery for analgesia and anesthesia. Repeated or continuous MNB has been used successfully as treatment for uncontrollable pain, masseter spasticity, and airway assessment. The usual technique involves transcutaneous infrazygomatic access. However, in some specific settings, this approach is not always feasible. MATERIALS AND METHODS: A continuous bilateral MNB with a suprazygomatic approach to the pterygomandibular space was used to resolve a case of refractory and painful trismus in a patient with tetraplegia...

BACKGROUND: The establishment of a golden standard for post-operative analgesia after thoracic surgery remains an unresolved issue. Benefiting from the rapid development of single port video-assisted thoracoscopic surgery (VATS), a good candidate for the alleviation of patients' pain is the placement of an intercostal catheter (ICC) safely after uniport VATS. We hypothesized that continual infusion through ICC could provide effective analgesia for patients with only one wound and we evaluate its postoperative analgesic function in uniport VATS patients with or without intercostal nerve blockade...

BACKGROUND AND OBJECTIVES: Although many studies have found no difference between thoracic epidural block and unilateral thoracic paravertebral block after thoracotomy, no previous studies have compared epidural block with bilateral thoracic paravertebral block (bTPVB) in patients undergoing open liver resection. We aimed to investigate whether there was a significant analgesic advantage of thoracic epidural over bTPVB after liver resection. METHODS: This randomized, prospective, open-label study included adult patients undergoing elective open liver resection...

Reverse open shoulder arthroplasty requires a comprehensive analgesic plan involving regional anesthesia. The commonly performed interscalene brachial plexus blockade confers a high likelihood of diaphragmatic paralysis via phrenic nerve palsy, making this option riskier in patients with limited pulmonary reserve. Continuous blockade of the suprascapular nerve, a more distal branch of the C5 and C6 nerve roots, may be a viable alternative. We report a successful case of the use of a suprascapular nerve block with continuous programmed intermittent bolus perineural analgesia in a patient with severe chronic obstructive pulmonary disease who underwent reverse open shoulder arthroplasty...

Fractured neck of femur (NOF) causes significant morbidity and pain for patients; adequate analgesia is an essential component of patient centred care. Patients experiencing greater pain during treatment for fractured NOF are slower to mobilise and have poorer health-related quality of life. NICE guidance suggests considering adding nerve blocks if paracetamol and opioids do not provide sufficient preoperative pain relief. We set out to audit pain levels in this group of patients in a small District General Hospital and to develop a protocol to improve analgesia provision if required...
