Lead migration is the most common complication of spinal cord stimulation (SCS). However, the only corrective method for lead migration is revision surgery, which may cause additional complications. Here, we describe a new technique for adjusting a transversely migrated SCS lead. The medical records of four patients diagnosed with complex regional pain syndrome (n = 3) or failed back surgery syndrome (n = 1) who underwent implantation of percutaneous leads for SCS were retrospectively reviewed. Transver...
Intravenous lipid emulsion (ILE; Intralipid) therapy, a standard treatment in local anesthetic toxicity, has demonstrated therapeutic efficacies for a number of different drug class-mediated toxicities. Some of these varied drug groups include antipsychotics, antidepressants, antiarrhythmics, and calcium channel blockers. To meet the objective of describing the growing number of indications for Intralipid therapy and any diverse effects and/or failures of Intralipid therapy in reversing multiple drug toxici...
Insulin-like growth factor 1 (IGF-1) and erythropoietin (EPO) have been reported to independently protect against ischemic spinal cord injury in rabbits. In the present study, we investigated whether the combination of IGF-1 and EPO protects against ischemic spinal cord injury in rabbits.
Many studies have been done to seek the relationship between general anesthesia and neurodevelopment in pediatrics. However, there is no unified conclusion, especially single anesthesia affecting a child before 3 and 4 years. The association between anesthesia and neurodevelopment is studied using a meta-analysis.
Hypoxia promotes the progression of lung cancer cells. Unfortunately, anesthetic technique might aggravate hypoxia of lung cancer cells. Sevoflurane is a commonly used anesthetic. Its effect on hypoxia-induced aggressiveness of lung cancer cells remains unknown. The aim of the study is to investigate the effects of sevoflurane on hypoxia-induced growth and metastasis of lung cancer cells. As hypoxia-inducible factor-1α (HIF-1α) plays a pivotal role in mediating the adaptation and tolerance of cancer cells...
Dextrocardia, a term used to describe all varieties of developmental malformations resulting in the positioning of the heart in the right hemithorax, is linked to a number of highly significant cardiac disorders. Current estimates vary tremendously in the literature. Only about 10 % of patients with diagnosed dextroversion show no substantial cardiac pathology; however, the incidence of congenital heart defects associated with dextrocardia is close to 100 %. The majority of studies previously reported inc...
Our previous study showed, for the first time, that a guideline-recommended thromboprophylactic strategy reduced the prevalence of venous thromboembolism (VTE) including venous thromboembolism and pulmonary embolism after arthroplasties of the major lower extremities, such as total hip arthroplasty (THA) or total or partial knee arthroplasty (TPKA), to 4.4 %. In this retrospective study, we examined the diagnostic value of D-dimer for VTE and try to confirm the low prevalence of VTE after THA or TPKA.
There are 26 teaching hospitals in Taiwan that provide anesthesia residency training programs (one program per hospital), and only an average of 40 medical graduates are accepted for residency training per year. The aim of this study is to understand how this situation affects the learning and working conditions of anesthesia residents in Taiwan.
This study investigated the hypothesis that the efficacy of insertion of the supraglottic device i-gel(®) (i-gel) can be improved by laryngoscopy and can provide better sealing pressure in anesthetized patients by novice doctors.
Although maintaining anesthesia for myasthenia gravis (MG) with minimal muscle relaxants (MR) is common, the success rate of anesthetic management for MG without MR is not clear. We therefore retrospectively examined the success rate of anesthetic management for MG without MR among 66 consecutive cases of thymectomy for MG performed at our hospital between January 2004 and April 2010, before approval of using sugammadex. A total of 60 patients (90.9 %) were treated without MR (N group). Among the 60 cases,...
Postoperative cognitive dysfunction (POCD) increases morbidity and mortality. The mechanisms underlying POCD remain elusive; however, systemic responses induced by anesthesia and surgery might trigger neuroinflammation and POCD. Desflurane is a preferable volatile anesthetic agent for elderly patients because it facilitates shorter recovery from general anesthesia. The aim of this study was to determine whether quality of emergence and cognitive function in elderly patients undergoing a long duration desflu...
Lidocaine has a biphasic action on smooth muscle of peripheral blood vessels, with vasoconstriction at low concentrations and vasodilation at higher concentrations. Many in vivo studies have demonstrated the effects of lidocaine on aortic or coronary arteries in several animals, but there are few reports about the effect on peripheral vessels. This study was designed to investigate the direct effects of lidocaine on peripheral vessels, namely swine lingual and pulmonary arterial rings.
Serotonin syndrome is a drug-related toxicity caused by excess serotonin within the central nervous system. We recently encountered a case of serotonin syndrome that developed in the early postoperative period that was successfully treated with intravenous dexmedetomidine. Although the prescriptive literature has commonly recommended sedation with benzodiazepines for controlling agitation in serotonin syndrome, the effectiveness of dexmedetomidine has also been reported in several clinical conditions. In th...
We sought to establish the clinical utility of the Pentax-AWS Airway Scope(®) (AWS) when used by paramedics to intubate the trachea, and to evaluate whether their performance was influenced by previous clinical experience with the Macintosh laryngoscope (ML).
Both paravertebral block (PVB) and thoracic epidural block (TEB) are recommended for postoperative pain relief after lung surgery. The addition of fentanyl to the anesthetic solution became popular for TEB because of the stronger effects; however, there have been few comparable trials about the addition of fentanyl to PVB. The purpose of this study was thus to compare postoperative analgesia, side effects, and complications between ultrasound-guided PVB (USG-PVB) and TEB with the addition of fentanyl to rop...
It is recommended that the period of fasting before elective surgery should be shortened to facilitate a rapid recovery by preventing catabolism. We examined the effects of a short period of fasting on metabolism by performing indirect calorimetry (IC) under general anesthesia. A prospective observational study involving 26 consecutive patients who underwent elective surgery and whose metabolism was evaluated using IC during anesthesia was conducted. The patients were divided into two groups, those who fast...
This observational study was designed to evaluate the clinical value of cardiac output (CO) obtained via bioreactance (NICOM™) as compared with values of CO obtained via thermodilution (using pulmonary artery catheter, Vigilance™) and the thoracic bioimpedance (BioZ.com™), in patients undergoing off-pump coronary artery bypass surgery.
Adductor canal catheters preserve quadriceps strength better than femoral nerve catheters and may facilitate postoperative ambulation following total knee arthroplasty. However, the effect of this newer technique on provider workload, if any, is unknown. We conducted a retrospective provider workload analysis comparing these two catheter techniques; all other aspects of the clinical pathway remained the same. The primary outcome was number of interventions recorded per patient postoperatively. Secondary out...
Remote ischemic preconditioning (RIPC) is a potent preconditioning stimulus that may confer subsequent protection to organs subjected to potentially lethal injury. The aim of this study was to investigate the effect of RIPC on nuclear factor (NF)-κB activation, tumor necrosis factor (TNF)-α release, and hepatic injury in lipopolysaccharide (LPS)-induced sepsis.
We performed a multicenter, randomized, double-blind trial to assess the efficacy and safety of a single, fixed, intravenous dose of palonosetron (0.075 mg) in the treatment of established postoperative nausea and vomiting (PONV).
Beta-defensins (BDs) and dendritic cells (DC) have been described as major effectors on host antimicrobial innate immunities. In the present study, the ability of DC to produce BDs was explored using DC from normal mice and full-thickness (FT)-burned mice.
