Catheter nerve analgesia

Axillary nerve blocks are commonly using for forearm and hand surgery. Especially for finger replacement it has been shown continuous plexus blockade improves microcirculation. Addition to that benefit continuous blockade provides adequate analgesia. In this study perfusion index (PI) and plethysmographic variability index (PVI) changes were used to evaluate in blocks success. The PVI and PI values were detected by a Radical-7TM finger pulse oximetry device (Massimo Corp, USA) in both fingers of 50 plastic surgery patients, who received an axillary brachial plexus catheter before surgery...

A 74-year-old male was diagnosed with osteomyelitis of the left mandible requiring marginal mandibulectomy under general anesthesia. However, the patient's pulmonary function tests demonstrated findings consistent with severe chronic obstructive pulmonary disease, classified as stage III. The consulting pulmonologist explained the increased risk of respiratory complications associated with general anesthesia and advised against its use. Therefore, we opted to perform the surgery under moderate sedation using 0...

PURPOSE: Total knee arthroplasty (TKA) is associated with severe postoperative pain. Continuous adductor canal blockade provides analgesia while preserving quadriceps muscle strength. Nevertheless, uncertainty still exists as to the optimal adductor canal catheter placement approach. We sought to conduct a systematic review and meta-analysis of randomized controlled trials (RCTs) comparing the analgesic effects of proximal vs distal adductor canal catheters in patients undergoing TKA...

Latissimus dorsi (LD) tendon rupture is a rare injury that occurs in athletes throughout a wide range of sports, including baseball, rock climbing, tennis, and golf. LD tendon repair requires analgesia in nerve distributions from C5-T6. A 33-year-old man presented for right LD tendon repair after rock climbing eight weeks prior to the operation. An interscalene nerve block catheter was placed preoperatively for postoperative pain control. After induction of general endotracheal anesthesia, a mid-axillary incision was made down to the sixth rib and the patient underwent LD tendon repair...

BACKGROUND: : Hypertonic saline is used for treating chronic pain; however, clinical studies that aid in optimizing therapeutic protocols are lacking. We aimed to determine the concentration of intrathecally injected hypertonic saline at which the effect reaches its peak as well as the underlying γ-aminobutyric acid (GABA) receptor-related antinociceptive mechanism. METHODS: : Spinal nerve ligation (SNL; left L5 and L6) was performed to induce neuropathic pain in rats weighing 250-300 g...

INTRODUCTION: Total knee arthroplasty is associated with significant postoperative pain. Continuous adductor canal blocks via an inserted adductor canal catheter are effective analgesia interventions with the advantage of decreasing quadriceps weakness and the potential of extending the analgesic effect. The classical adductor canal catheter insertion technique may have a high likelihood of catheter dislodgement out of the canal. The interfascial plane between the sartorius muscle and femoral artery (ISAFE) approach has the potential of decreasing the adductor canal catheter migration...

Critical limb ischemia (CLI) is limb pain occurring at rest or impending limb loss as a result of lack of blood flow to the affected extremity. CLI pain is challenging to control despite multimodal pharmacologic analgesia and surgical intervention. We describe the successful use of a continuous local anesthetic infusion via an infraclavicular nerve catheter to control severe refractory ischemic upper limb pain in a patient with metastatic lung cancer for whom surgical and pharmacological intervention was unsuccessful...

BACKGROUND: There are few studies on continuous intercostal nerve block after single operation hole thoracoscopic surgery, i.e., two-port thoracoscopic surgery. OBJECTIVE: To evaluate the analgesic effect of continuous intercostal nerve block after thoracoscopic surgery. METHODS: A total of 80 patients who underwent single operation hole thoracoscopic surgery in our hospital between September 2020 and June 2021 were enrolled and divided into two groups...

Aim: Anesthesia for cardiac surgery has evolved toward fast-track recovery strategies incorporating non opioid analgesics and regional anesthesia. Materials & methods: This retrospective cohort study compared opioid consumption, pain scores and length of stay in patients who underwent cardiac surgery via median sternotomy and did or did not receive preoperative parasternal intercostal plane block catheters with postoperative ropivacaine infusions. Results: Postoperative opioid consumption and postoperative pain scores did not differ...

BACKGROUND AND AIMS: Pain associated with rib fractures is challenging to manage. This pilot trial aimed to assess the efficacy of erector spinae plane block (ESPB) compared with thoracic epidural analgesia (TEA) for controlling pain associated with multiple rib fractures. METHODS: This randomised, single-blinded, controlled pilot study was conducted on trauma patients who had three or more rib fractures and had been admitted at a tertiary care centre. The study was conducted after receiving ethical approval and trial registration...

OBJECTIVES: The present study compared the surgical wound catheter (SWC), femoral nerve block (FNB), and adductor canal block (ACB) for postoperative analgesia after knee arthroplasty. METHODS: The study included (180) patients scheduled for unilateral total knee replacement and were randomly allocated into three groups. Patients received postoperative analgesia via continuous infusion of ropivacaine 0.2% (10 ml bolus followed by continuous infusion of 5 ml/hour) through the SWC, FNB, or ACB groups...

BACKGROUND: Optimal pain management after insertion of a central venous catheter in children remains unclear. AIM: This study aimed to evaluate the effects of a selective supraclavicular nerve block on postoperative analgesia in pediatric patients undergoing hickman catheter or chemoport insertion. METHODS: Fifty patients aged 3-18 years scheduled for elective Hickman or chemoport insertion were randomized into two groups of 25 each: one group received an ultrasound-guided selective supraclavicular nerve block with 0...

PURPOSE OF REVIEW: To summarize the recent literature describing and comparing novel motor-sparing peripheral nerve block techniques for hip and knee surgery. This topic is relevant because the number of patients undergoing same day discharge after hip and knee surgery is increasing. Preserving lower extremity muscle function is essential to facilitate early physical therapy for these patients. RECENT FINDINGS: Distal peripheral nerve blocks may allow for preserved quadriceps motor strength and comparable analgesia to traditional techniques...

Peripheral arterial disease (PAD) patients often require surgical peripheral vascular revascularization (PVR), in which postoperative pain management can be challenging. This case report details a 43-year-old female patient with PAD who underwent urgent femoral popliteal bypass with an inverted ipsilateral great saphenous vein and left femoral endarterectomy. Due to contraindications for neuraxial anesthesia and the necessity for continuous anticoagulation, the procedure was performed under general anesthesia (GA) and an unconventional technique with intraoperative perineural catheter (PC) placement to guarantee adequate postoperative analgesia...

BACKGROUND: Combined suprascapular and axillary nerve block could be an analgesic option for shoulder pain control. The current description of this technique requires performing the block procedures at two different sites without consideration for catheter placement. We hypothesized that a single site injection to the interfascial plane between the infraspinatus and teres minor would result in an injectate spread to the suprascapular and axillary nerves. METHODS: We performed 10 injections with this approach using 25 mL dye solution in 10 shoulders of five unembalmed cadavers...

INTRODUCTION: Pectus excavatum repair by the Nuss procedure results in severe postoperative pain. Regional blocks and intercostal nerve cryoablation (INC) have emerged as potential strategies to manage analgesia. This study compares pain-related outcomes following these perioperative interventions. METHODS: We reviewed charts of patients <18 y who underwent the Nuss procedure at Duke Children's Hospital from July 2018 to June 2022. Patients were divided into three groups by analgesic strategy: no block, regional catheters, or INC, representing the chronologic change in our practice...

BACKGROUND: External Oblique Intercostal (EOI) fascial plane blockade is a relatively new regional anesthetic technique used for a variety of upper abdominal surgical procedures. Proponents of this block praise its simple sonoanatomy, extensive local anesthetic (LA) spread, and ease of catheter placement, while avoiding encroachment into the surgical field or dressing sites; nevertheless, it is underutilized in pediatric surgery. Kasai portoenterostomy is a common pediatric surgical procedure for biliary atresia typically done via an open abdominal approach with an extended subcostal incision...

BACKGROUND: The quadratus lumborum block (QLB) has recently been used frequently for postoperative analgesia after abdominal surgery. The aim of this study was to investigate the effect of pressure changes between the middle thoracolumbar fascia layers to which the anterior QLB (aQLB) is applied at the level of the sensory block. METHODS: A total of 67 patients planned to undergo laparoscopic cholecystectomy were evaluated in the context of this prospective study...

OBJECTIVE: Percutaneous nephrolithotomy (PCNL) is accompanied by somatic and visceral pain intraoperatively and postoperatively. However, pain management strategies lack a decisive consensus. Erector spinae plane block (ESPB) is a novel paraspinal fascial block that can be used in PCNL patients, and we aimed to investigate whether ESPB will reduce intraoperative and postoperative opioid consumption and postoperative pain scores in PCNL patients. METHODS: The study was randomized, controlled, and open-label...

BACKGROUND: Single-shot suprascapular nerve block and superior trunk block have been reported to provide a noninferior analgesic effect after shoulder surgery with a lesser incidence of hemidiaphragmatic paresis compared with interscalene brachial plexus block. This study hypothesized that continuous suprascapular nerve block provides noninferior analgesia with minimal effects on diaphragmatic movement compared with continuous superior trunk block in patients undergoing arthroscopic shoulder surgery...
