Three-dimensional pelvis computed tomography-assisted Taylor approach for spinal anesthesia in hip arthroplasty: a retrospective study.

Background: Needle insertion for spinal anesthesia using the Taylor approach is challenging as the L5-S1 space is difficult to locate from the surface anatomy. In this study, we suggest the use of three-dimensional (3D) pelvis computed tomography (CT) to assist anesthesiologists in locating the needle insertion point. By comparing the success rate of 3D pelvis CT-assisted Taylor approach to that of other approaches in the existing literatures, we suggest this technique as an alternative method for subarachnoid block in the L5-S1 space.

Ultrasound-guided pulsed radiofrequency of the saphenous nerve in a complex regional pain syndrome patient with lower limb pain.

Complex regional pain syndrome is a painful and debilitating syndrome in which the patient presents with disabling pain, edema, and/or vasomotor or sudomotor abnormalities. The mechanism is complex and not well understood. There is no definitive treatment for the condition yet.

Postoperative expressive aphasia associated with intravenous midazolam administration: a 5-year retrospective case-control study.

Objectives: This study aimed to investigate the epidemiology of intravenous midazolam-induced postoperative expressive aphasia (EA).

Methods: The incidence rate, risk ratio, and contributing factors to intravenous midazolam-induced postoperative EA were analyzed retrospectively in 6756 orthopedic patients. A telephone interview was conducted with patients with EA after surgery.

Analysis of temperature-dependent abnormal bursting patterns of neurons in .

Temperature affects the firing pattern and electrical activity of neurons in animals, eliciting diverse responses depending on neuronal cell type. However, the mechanisms underlying such diverse responses are not well understood. In the present study, we performed in vitro recording of abdominal ganglia cells of , and analyzed their burst firing patterns.

Patient-specific depth of endotracheal intubation-from anthropometry to the Touch and Read Method.

Objective: Knowledge of accurate airway length (AL) enables safer placement of the endotracheal tube (ETT) in the trachea. Our objective was to check the safety of a new formula (Touch and Read method) to determine ETT depth.

Methods: AL was measured in 176 patients.

Prediction of compensatory hyperhidrosis with botulinum toxin A and local anesthetic.

Objective: Compensatory hyperhidrosis (CH) is one of the most problematic complications of sympathectomy, which occurs often and is hard to treat. A predictive procedure (PP) for CH can help patients experience compensatory sweating before sympathectomy to determine whether or not to perform sympathectomy. Our study aimed to evaluate the CH after the PP and sympathectomy in patients with primary palmar hyperhidrosis using multiple drugs.

Anti-morphine antibody contributes to the development of morphine tolerance in rats.

Previous studies have shown that tolerance to the antinociceptive effect of morphine develops after a prolonged exposure, but its mechanisms remain unclear. In the present study, we examined whether anti-morphine antibody produced by chronic morphine exposure would contribute to the development of morphine antinociceptive tolerance in rats. Our results showed that anti-morphine antibody was present in rats rendered tolerance to antinociception after intrathecal morphine exposure for seven consecutive days.
