Generic rocuronium reduces withdrawal movements compared to original rocuronium under target-controlled infusion induction with propofol.

Purpose: Rocuronium-induced injection pain often causes withdrawal movements leading to accidental disruption of indwelling needles. Generic rocuronium (Maruishi Pharmaceutical Co., Ltd, Osaka, Japan) with a novel solution has been reported to reduce the injection pain compared to original rocuronium [Esmeron (Eslax), MSD Co.

Epidural analgesia for the treatment of colic attack with retrocaval ureter in late pregnancy complicated with marginal placenta previa: a case report.

Background: Retrocaval ureter was diagnosed in a woman complaining of ureteric pain in the last trimester of pregnancy. We describe the rationale behind the administration of epidural analgesia for her colic attack.

Case Presentation: A 41-year-old pregnant woman was hospitalized with a diagnosis of a marginal placenta previa at 34 weeks and 5 days of pregnancy.

A case of a warfarinized renal cancer patient monitored for prothrombin time-international normalized ratio during methadone introduction.

Background: Warfarin, a widely used anticoagulant, interacts with various agents used in palliative care, such as oxycodone, morphine, acetaminophen, and non-steroidal anti-inflammatory drugs (NSAIDs); however, there are no reports of its interaction with methadone. We report a case of a patient receiving warfarin when methadone was introduced for pain control with monitoring of the prothrombin time-international normalized ratio (PT-INR) and deduced the pharmacological background.

Case Presentation: A 60-year-old male was emergently admitted to our university hospital for the sudden onset of severe back pain.

Three cases of implantation of a SureScan system and MRI for investigating causes of pain.

We report three cases of implantation of the SureScan system and magnetic resonance imaging (MRI) for investigating causes of pain. Although there were metal-induced artifacts on the MR images of 2 patients, the artifacts did not affect the images of structures that needed to be assessed to make the diagnosis. The SureScan system enabled patients implanted with spinal cord stimulation devices to undergo MRI.

Quadratus Lumborum Block: Analgesic Effects and Chronological Ropivacaine Concentrations After Laparoscopic Surgery.

Background And Objectives: The quadratus lumborum block (QLB) is an abdominal truncal block, similar to transversus abdominis plane block (TAPB). However, the characteristics of QLB with regard to its duration and safety are not well known. The primary aim of this study was to determine the block duration and the cutaneous sensory block area.

Chronological Changes in Ropivacaine Concentration and Analgesic Effects Between Transversus Abdominis Plane Block and Rectus Sheath Block.

Background And Objectives: Transversus abdominis plane block (TAPB) and rectus sheath block (RSB) are popular methods of controlling postoperative pain. Chronological changes in blood concentrations of local anesthetics have not been described, although a large amount of local anesthetic is required to block these compartments. We postulated that blood concentrations of anesthetics would peak earlier during TAPB than RSB (primary end point).

[Craniotomy in a pediatric patient complicated with insufficiently controlled diabetes mellitus: intraoperative management with remifentanil and an electrolyte-containing glucose solution].

An 8-year-old girl of Type 1 diabetes mellitus on insulin therapy, was surgically treated for brain cavernous hemangioma. Since the hemangioma gradually became larger, the medical team including anesthesiologists, neurosurgeons, and pediatricians discussed and decided to perform craniotomy. Preoperative blood sugar level was around 40 to 300 mg x dl(-1) and appeared poorly controlled.

Tracheal Intubation through the I-gel for Emergency Cesarean Section in a Patient with Multidrug Hypersensitivity: A New Technique.

31-year-old female with hypersensitivity to local anesthetics and neuromuscular blocking agents presented for emergency Cesarean section. We successfully performed I-gel-assisted tracheal intubation without using neuromuscular blockers. We believe this method would be helpful in selected situations.

[Acute cervical spinal cord injury].

Cervical spinal cord injury is a tragic trauma causing immediate serious quadriplegia and respiratory paralysis. In unstable injuries with paralysis, emergency surgery must be performed immediately to achieve spinal cord decompression and spinal column stabilization. In the treatment of dislocation fractures, first priority should be given to reducing the dislocation, by which the spinal cord is decompressed.

Different inhibitory effects of sevoflurane on hyperreactive airway smooth muscle contractility in ovalbumin-sensitized and chronic cigarette-smoking guinea pig models.

Background: The authors hypothesized that sevoflurane had different inhibitory effects on hyperreactive airway smooth muscle contractility in different types of hyperreactive airway models.

Methods: The effects of sevoflurane on hyperreactive airways in ovalbumin-sensitized and chronic cigarette-smoking guinea pig models were investigated by measuring (1) total lung resistance, (2) smooth muscle tension and intracellular concentration of free Ca, (3) voltage-dependent Ca channel activity, and (4) cyclic adenosine monophosphate levels.

Results: Ovalbumin and muscarinic airway hyperreactivity was seen in ovalbumin-sensitized animals.
