Tomoki Nishiyama
BACKGROUND: To know the objective methods of the effects of the brachial plexus block, we studied the changes in percutaneous oxygen pressure (tcPO₂) with the hypothesis that tcPO₂ increases significantly on the blocked arm in comparison with the non-blocked arm, a phenomenon which is connected with vasodilation following the brachial plexus block. METHODS: Fifteen patients scheduled for upper extremity surgery, aged 20 to 70 years, with ASA physical status I or II were included...

PURPOSE OF REVIEW: A majority of surgical practice has involved ambulatory centers with the number of outpatient operations in the USA doubling to 26.8 million per year. Local anesthesia delivery provides numerous benefits, including increased satisfaction, earlier discharge, and reduction in unplanned hospital admission. Further, with the epidemic of opioid mediated overdoses, local anesthesia can be a key tool in providing an opportunity to reduce the need for other analgesics postoperatively...

OBJECTIVE: Accumulating data have recently underlined argon´s neuroprotective potential. However, to the best of our knowledge, no data are available on the cerebrovascular effects of argon (Ar) in humans. We hypothesized that argon inhalation does not affect mean blood flow velocity of the middle cerebral artery (Vmca), cerebral flow index (FI), zero flow pressure (ZFP), effective cerebral perfusion pressure (CPPe), resistance area product (RAP) and the arterio-jugular venous content differences of oxygen (AJVDO2), glucose (AJVDG), and lactate (AJVDL) in anesthetized patients...

Common marmosets (Callithrix jacchus), small New World primates, are increasingly attracting attention as potentially useful animal models for drug development. However, characterization of cytochrome P450 (P450) 3A enzymes involved in the metabolism of a wide variety of drugs has remained in marmosets. In this study, sequence homology, tissue distribution, and enzymatic property of marmoset P450 3A4 orthologue, 3A5 orthologue, and 3A90 were investigated. Marmoset P450 3A forms exhibited high amino acid sequence identities (88-90%) to the human and cynomolgus monkey P450 3A orthologues and evolutionary closeness to human and cynomolgus monkey P450 3A orthologues, compared with other P450 3A enzymes...

This study aimed to assess whether a single oral dose of the nonnucleoside reverse transcriptase inhibitor efavirenz can alter CYP3A in vivo. In 12 healthy participants individual CYP3A activity was quantified using a semisimultaneous methodology (midazolam orally and 6 hours later intravenously) both alone and during a period of 22 days after a single oral dose of 400 mg efavirenz. Twelve hours after efavirenz administration, midazolam apparent oral clearance was significantly increased by 70%, and midazolam systemic clearance after intravenous administration was significantly increased by 27%...

BACKGROUND: Conscious sedation has been widely utilized in plastic surgery. However, inadequate research has been published evaluating adequate drug dosage and depth of sedation. In clinical practice, sedation is often inadequate or accompanied by complications when sedatives are administered according to body weight alone. The purpose of this study was to identify variables influencing the depth of sedation during conscious sedation for plastic surgery. METHODS: This prospective study evaluated 97 patients who underwent plastic surgical procedures under conscious sedation...

STUDY OBJECTIVE: The majority of children scheduled to undergo surgery experience substantial anxiety in the preoperative holding area before induction of anesthesia. Pharmacological interventions aimed at reducing perioperative anxiety are paradoxically a source of stress for children themselves. Midazolam is frequently used as premedication, and the formula of this drug in Turkey is bitter. We aimed to assess the role of distraction in the form of playing with play dough (Play-Doh) on reducing premedication anxiety in children...

BACKGROUND: The incidences of morbidity and mortality caused by pharmacosedation for dental treatment have not yet reached zero. Adverse events are related to inappropriate respiratory management, mostly originating from an overdose of sedatives. Since sedation is utilized for the satisfaction of both the dentist and the patient, the optimal dose should be minimized to prevent adverse events. We attempted to define the optimal doses of midazolam and propofol required to achieve high levels of patient and dentist satisfaction...

Introduction. Status epilepticus is associated with neuronal breakdown. Radiological sequelae of status epilepticus include diffusion weighted abnormalities and T2/FLAIR cortical hyperintensities corresponding to the epileptogenic cortex. However, progressive generalized cerebral atrophy from status epilepticus is underrecognized and may be related to neuronal death. We present here a case of diffuse cerebral atrophy that developed during the course of super refractory status epilepticus management despite prolonged barbiturate coma...

AIM: There is no consensus regarding the administration of stimulant drugs preoperatively, particularly in pediatric patients diagnosed with ADHD. The primary objective of the current study was to assess differences in blood pressure and heart rate before and after induction of anesthesia between patients on chronic amphetamine or methylphenidate therapy who receive their normal dose preoperatively compared to patients in whom the prescribed medication was withheld. Secondary objectives were to assess the anxiety level during the induction of anesthesia and the effect of premedication with midazolam...

BACKGROUND AND OBJECTIVE: Midazolam is the drug of choice for palliative sedation and is titrated to achieve the desired level of sedation. Because of large inter-individual variability (IIV), however, the time it takes to achieve adequate sedation varies widely. It would therefore greatly improve clinical care if an individualised dose could be determined beforehand. To find clinically relevant parameters for dose individualisation we performed a pharmacokinetic study on midazolam, 1OH-midazolam (1-OH-M) and 1OH-midazolam-glucuronide (1-OH-MG) in terminally ill patients...

BACKGROUND: Conscious sedation is regularly used in ambulatory surgery to improve patient outcomes, in particular patient satisfaction. Reports suggest that the addition of conscious sedation to local anesthesia for inguinal hernioplasty is safe and effective in improving patient satisfaction. No previous randomized controlled trial has assessed the benefit of conscious sedation in this regard. OBJECTIVE: To determine whether the addition of conscious sedation to local anesthesia improves patient satisfaction with inguinal hernioplasty...

BACKGROUND AND AIMS: Current guidelines recommend diphenhydramine in patients undergoing endoscopy who are not adequately sedated with a benzodiazepine and opioid combination. Because this practice has not been adequately assessed, we performed a randomized, double-blind trial comparing diphenhydramine to continued midazolam in such patients. METHODS: Patients undergoing elective colonoscopy with moderate sedation were eligible. Sedation was measured with the modified observer's assessment of alertness/sedation (MOAA/S) score with adequate sedation defined as 3 on a 0 to 5 scale...

BACKGROUND: Midazolam is commonly and safely used in poisoning management and intensive care for the control of agitated poisoned patients. Despite the introduction of newer and safer antidepressants, tricyclic antidepressants (TCAs) are still prescribed and used in many countries due to their cost-effectiveness. Severe morbidity and mortality associated with these drugs arises largely from their well-documented cardiovascular toxicity. In this study we aimed to investigate the probable effect of midazolam on some hemodynamic indices in TCAs-poisoned patients...
