Spectral analysis of heart rate variability provides a probe to assess the function of the sympathetic and parasympathetic nervous systems. Time-frequency analysis of heart rate variability is useful for investigating autonomic nervous function in patients with syncope or non-sustained ventricular tachycardia, or in anaesthesia, etc. In this paper, we(More)
BACKGROUND Smooth and successful insertion of a laryngeal mask airway (LMA) during etomidate induction requires a proper mouth opening and efforts to minimize airway reflexes such as gagging, coughing, or laryngospasm. We hypothesized that the concurrent use of fentanyl or succinylcholine with etomidate, the induction agent, could reduce the occurrence of(More)
To evaluate whether chronic cocaine abuse will increase cardiac Fas-dependent and mitochondria-dependent apoptotic pathways, thirty-two male Wistar rats at 3-4 months of age were randomly divided into a vehicle-treated group (phosphate-buffered saline, PBS, 0.5 mL, SQ per day) and a cocaine-treated group (Cocaine, 10 mg/kg, SQ per day). After 3 months of(More)
Very limited information regarding the influence of chronic methamphetamine exposure on cardiac apoptosis is available. In this study, we evaluate whether chronic methamphetamine exposure will increase cardiac Fas-dependent (type I) and mitochondria-dependent (type II) apoptotic pathways. Thirty-two male Wistar rats at 3–4 months of age were randomly(More)
To determine the neurophysiological effects of aminophylline on apnoea of prematurity, the brain stem auditory evoked potentials (BAEPs) of 30 apnoeic infants and 34 age matched controls were evaluated and compared. After six days of treatment with aminophylline, the brain stem conduction time (interpeak latency of I-V) in apnoeic infants decreased compared(More)
Human circulating lymphocytes were isolated and incubated with ethanol. Cytosolic, membrane-bound and total detergent extractable protein kinase C (PKC) activities were measured. Exposure to ethanol (100 mm) resulted in an increase in PKC activity, with membrane-associated PKC activity increasing with respect to cytosolic activity at 5 min of exposure.(More)
STUDY OBJECTIVE To analyze whether emergence agitation could be reduced by using a low dosage of fentanyl without causing an increase in postoperative adverse effects and/or affecting the patient's quality of life after discharge. DESIGN Randomized, controlled crossover trial. SETTING University medical center. PATIENTS One hundred ten ASA physical(More)
Dental injury is a common complication associated with endotracheal general anesthesia. According to a study in Japan, the incidence of dental injury caused by endotracheal intubation is 0.69%. In one study in our country, evaluation of the oral condition was performed before, during and after anesthesia, and the frequency of dental trauma is as high as(More)
Measuring a patients’ oxygen consumption ( $$ {\dot{\text{V}}}{\text{O}}_{2} $$ ) is valuable in critical care and during anesthesia. Up to now, there has been no satisfactory equation describing the relation between the $$ {\dot{\text{V}}}{\text{O}}_{2} $$ , the fresh gas, and FIO2 in a semi-closed circle breathing system. By adopting a “volume-weighted(More)
BACKGROUND Acetazolamide has been investigated for treating sleep apnea in newcomers ascending to high altitude. This study aimed to assess the effect of acetazolamide on sleep apnea at high altitude, determine the optimal therapeutic dose, and compare its effectiveness in healthy trekkers and obstructive sleep apnea (OSA) patients.
