Evaluation of laparoscopic-guided rectus sheath block in gynecologic laparoscopy: a prospective, double-blind randomized trial.

Ultrasound-guided nerve blocks are effective; however, their use in the abdominal wall is reportedly associated with a risk of abdominal organ injury. Laparoscopic-guided nerve blocks are thought to be safer than ultrasound-guided nerve blocks. We evaluated the safety and effectiveness of the laparoscopic-guided rectus sheath block (LGRSB) for umbilical incisions after gynecologic laparoscopy.

Single Injection Ultrasound-Guided Rectus Sheath Blocks for Children: Distribution of Injected Anesthetic.

Single injection ultrasound guided rectus sheath blocks are used for postoperative analgesia after midline abdominal incisions, but the ultrasonographic spread of medication posterior to the rectus muscle has not been investigated.

Inadvertent Spinal Anesthesia During Ultrasound-Guided Thoracic Paravertebral Nerve Block in a Patient With Nerve Root Sheath Cyst: A Case Report.

An ultrasound-guided thoracic paravertebral nerve block was administered for left-sided abdominal pain. Lidocaine 0.4% (9.5 mL) was injected. Spinal anesthesia developed after the injection that resolved after 3 hours. One week later, a magnetic resonance imaging scan of thoracic spine identified a left T10 nerve root sheath cyst. It was postulated that the local anesthetic was injected into the cyst, which communicated with the subarachnoid space. This case report demonstrates the anatomic variations of ne...

Measurement of block thresholds in kiloHertz frequency alternating current peripheral nerve block.

Kilohertz frequency alternating currents (KHFAC) produce rapid nerve conduction block of mammalian peripheral nerve and have potential clinical applications in reducing peripheral nerve hyperactivity. The experimental investigation of KHFAC nerve block requires a robust output measure and this has proven to be the block threshold (BT), the lowest current or voltage at which the axons of interest are completely blocked. All significant literature in KHFAC nerve block, both simulations and experimental, were ...

Separate block-based parameter estimation method for Hammerstein systems.

Different from the output-input representation-based identification methods of two-block Hammerstein systems, this paper concerns a separate block-based parameter estimation method for each block of a two-block Hammerstein CARMA system, without combining the parameters of two parts together. The idea is to consider each block as a subsystem and to estimate the parameters of the nonlinear block and the linear block separately (interactively), by using two least-squares algorithms in one recursive step. The i...

A Preliminary Assessment of Abdominal Wall Tension in Patients Undergoing Retromuscular Hernia Repair.

A common technique for ventral and incisional hernia repair is the retrorectus repair (Rives-Stoppa). The posterior rectus sheath is incised bilaterally, and mesh is placed retromuscularly. There is little information on how this component separation technique affects abdominal wall tension. We evaluated abdominal wall tension in patients undergoing retrorectus repair of abdominal wall hernias. Patients undergoing retrorectus repair of their ventral hernias were enrolled in a prospective, Institutional Revi...

The management of large-angle esotropia in Graves ophthalmopathy with combined medial rectus recession and lateral rectus resection.

To describe surgical management and outcomes for large-angle esotropia of ≥50 secondary to Graves ophthalmopathy using combined initial nonadjustable medial rectus recessions and lateral rectus resections.

A comparison study of deep muscle sparing transverse rectus abdominis musculocutaneous flap for breast reconstruction.

Breast reconstruction by deep inferior epigastric perforator flap (DIEP) involves only little rectus abdominis muscle sacrifice. However, the operative procedure may get complicated. We propose here a novel method involving two adjacent perforators and requiring the addition of only the superficial muscle to the flap. This novel technique, termed "deep muscle sparing transverse rectus abdominis musculocutaneous flap (DMS-TRAM)," was compared to DIEP and MS-TRAM groups.

Brachial plexus block of the posterior and the lateral cord using ropivacaine 7.5 mg/mL.

We recently showed that the novel combination of a superficial cervical plexus block, a suprascapular nerve block, and the lateral sagittal infraclavicular brachial plexus block (LSIB) provides an alternative anaesthetic method for arthroscopic shoulder surgery. In this study, we hypothesised that the LSIB dose for this shoulder block could be significantly reduced by injecting only towards the shoulder relevant posterior and lateral cords. Our aim was to determine the minimum effective volume in 50% of the...

Time-dependently slow-released multiple-drug eluting external sheath for efficient long-term inhibition of saphenous vein graft failure.

Coronary artery bypass graft surgery (CABG) is an effective therapeutic method for coronary artery disease. Great saphenous vein is the predominant graft due to the accessibility, sufficient length and suitable size matching with coronary artery. However, saphenous vein graft failure (SVGF) always restrict the long-term success of CABG. In this study, a complex external sheath was prepared using multi-channel and coaxial electrospinning techniques. The sheath can slowly release fasudil dihydrochloride (100%...

Diffusion effects in myelin sheath free induction decay.

Myelin sheath microstructure and composition produce MR signal decay characteristics that can be used to evaluate status and outcome of demyelinating disease. We extend a recently proposed model of neuronal magnetic susceptibility, that accounts for both the structural and inherent anisotropy of the myelin sheath, by including the whole dynamic range of diffusion effects. The respective Bloch-Torrey equation for local spin dephasing is solved with a uniformly convergent perturbation expansion method, and th...

Intramuscular Nerve Distribution in the Medial Rectus Muscle and Its Clinical Implications.

The intramuscular nerve distribution in the extraocular muscles may be crucial for understanding their physiological and pathological responses. This study aimed to determine the oculomotor nerve distribution in the medial rectus muscle (MR) using Sihler's staining.

A one-sheath inverse method in vascular access intervention therapy for hemodialysis patients.

Vascular access intervention therapy (VAIVT) is an essential interventional therapy in the field of hemodialysis therapy that allows for the long-term vascular access functionality to be maintained. The venous approach is often performed in VAIVT for arteriovenous fistula. When lesions are present on the upstream and downstream sides from the approach site, it is likely that two sheaths will be inserted from two facing punctures. However, we have adopted a one-sheath inverse method using a guidewire in such...

Transposition procedures in Duane retraction syndrome.

Duane retraction syndrome, or Duane syndrome (DS), is one of several congenital cranial dysinnervation disorders. Patients present with limited horizontal eye movement(s) and globe retraction with eyelid fissure narrowing on attempted adduction due to co-contraction of the lateral and medial rectus muscles in one or both eyes. Various surgical approaches have been proposed to improve binocular alignment, reduce head turn, and minimize undesirable up- or downshoots in DS. Transposition procedures are one suc...

Continuous Popliteal-Sciatic Blocks for Postoperative Analgesia: Traditional Proximal Catheter Insertion Superficial to the Paraneural Sheath Versus a New Distal Insertion Site Deep to the Paraneural Sheath.

We tested the hypothesis that during a continuous popliteal-sciatic nerve block, postoperative analgesia is improved with the catheter insertion point "deep" to the paraneural sheath immediately distal to the bifurcation between the tibial and common peroneal branches, compared with the traditional approach "superficial" to the paraneural sheath proximal to the bifurcation. The needle tip location was determined to be accurately located with a fluid bolus visualized with ultrasound; however, catheters were ...
