[Clinical Trials for Thyroidectomy Under Acupuncture-aided Anesthesia by Using Electroacupuncture or Transcutaneous Acupoint Electrical Stimulation of Different Acupoints].

Objective: To observe the effectiveness of transcutaneous acupoint electrical stimulation (TAES) or electroacupuncture (EA) stimulation of different acupoints in combination with anesthetics in the management of thyroidectomy patients, so as to choose a better stimulating method and most effective acupoints for thyroidectomy.

Methods: A total of 216 thyroidectomy patients (ASA Ⅰ-Ⅱ grades) with thyroid gland adenoma, thyroid cyst or thyroid nodules from 3 hospitals (3 research centers) were randomized into 6 groups, i.e.

[The feasibility of training anesthesiologists with hemodynamic models of miniature pigs].

Objective: To investigate the feasibility of training anesthesiologists with hemodynamic models of miniature pigs.

Methods: Eight miniature experimental pigs were chosen; ECG, SpO2, PetCO2, ABP, CVP, SV, SVV and PAP were monitored after anesthesia. The research was divided into two parts.

The utility of using the bispectral index-Vista for detecting cross-clamping decline in cerebral blood flow velocity.

Background: Patients undergoing carotid endarterectomy for extracranial internal carotid artery stenosis are at risk of cerebral ischemia/hypoperfusion. Criterion recommended by European and American committees to determine whether to place a shunt consisted of a decline in transcranial Doppler ultrasonography-measured middle cerebral artery blood flow velocity (MCBFV) to < 30% to 40% of intraoperative preclamp value.

Objective: To assess the discriminative power of the bispectral index (BIS)-Vista monitor for detecting a 40% decline in MCBFV with cross-clamping.

[Investigation and analysis of status in simulation education of anesthesiology of China].

Objective: To investigate the status of simulation education of anesthesiology in China.

Methods: Five hundreds questionnaires were mailed to chairmen of department of anesthesiology in teaching hospitals in 29 provinces and autonomous regions in China. The retrieved questionnaires and data were processed and analyzed with statistics.

BIS-vista occipital montage in patients undergoing neurosurgical procedures during propofol-remifentanil anesthesia.

Background: Neurosurgical procedures that require a frontal approach could be an impediment for a successful Bispectral Index (BIS) frontal sensor placement. The aim of this study was to explore the utility of using the new BIS-Vista monitor (Aspect Medical Systems, Newton, MA) for occipital sensor placement in the patients undergoing brain neurosurgical procedures during propofol-remifentanil anesthesia.

Methods: Two BIS Quatro sensors (Aspect Medical Systems, Newton, MA) mounted on the occipital and frontal regions were connected to two BIS-Vista monitors at three anesthesia states: before induction, during anesthesia maintenance, and recovery.

[Exploration and application by combining human patient simulator drivers of critical and emergency events with micro-division teaching during training primary residents].

Objective: To explore the feasibility of combining human patient simulator (HPS) drivers with micro-division teaching during primary resident training by George Miller' medical education step-wised principle of goal and competence.

Method: The 20 residents from department of anesthesia who are less than 3 years in clinical training were randomized into two Groups. The all residents in Group T received HPS training, and no HPS training in Group N.

Bispectral index monitoring of a narcolepsy-cataplexy episode during regional anesthesia.

Narcolepsy or Gélineau syndrome is an extremely incapacitating chronic sleep disorder of unknown etiology that is characterized by uncontrollable attacks of deep sleep and is typically associated with cataplexy sudden loss of muscle tone. The Bispectral Index (BIS), an electroencephalographic-derived cerebral monitor, used for monitoring the effects of anesthetic/hypnotic drugs was shown to correlate to various conditions that could influence the eletroencephalogram. We assessed the utility of using BIS for monitoring a possible narcolepsy-cataplexy episode and whether a distinctive BIS profile might offer an early warning of an impending narcoleptic/cataplectic spell.
