Randomized Controlled TrialEffect of ketamine on bispectral index during propofol--fentanyl anesthesia: a randomized controlled study.
The Bispectral Index (BIS) helps in the assessment of the depth of hypnosis. N-methyl-D-aspartic acid antagonist, ketamine, has been used in various doses to decrease postoperative morphine consumption. The purpose of our study was to compare the effects of two different doses (0.5 mg/kg and 0.2 mg/kg) of ketamine on BIS values. ⋯ Thus, under stable propofol anesthesia, a bolus ofketamine 0.5 mg/kg increases BIS values while ketamine 0.2 mg/kg does not.

Randomized Controlled Trial Comparative StudyComparison between ropivacaine 1.5 mg ml(-1) plus fentanyl 2 mg ml(-1) and ropivacaine 1.5 mg ml(-1) plus clonidine 1 mg ml(-1) as analgesic solution after anterior cruciate ligament reconstruction: a randomized clinical trial.
Ropivacaine is commonly used as local anesthetic for postoperative analgesia through an epidural catheter. Data show that several adjuvants influence the analgesic effect of local anesthetic potency. ⋯ Ropivacaine 1.5 mg ml(-1) plus fentanyl 2 microg ml(-1) administred through PCEA compared with ropivacaine 1.5 mg ml(-1) plus clonidine 1 microg ml(-1) h guarantee higher quality analgesia after ACL reconstruction.

Randomized Controlled TrialReduced hemodynamic responses to tracheal intubation by the Bonfils retromolar fiberscope: a randomized controlled study.
The Bonfils retromolar intubation fiberscope is a rigid endoscope designed to enable glottic visualization and facilitate intubation under endoscopic vision. Theoretically, avoiding direct-vision laryngoscopy and thus could produce less stimulation during intubation than the conventional direct laryngoscopic procedure. This prospective randomized study was designed to compare the effect of tracheal intubation with direct vision laryngoscopy (Macintosh blade) and the Bonfils retromolar intubation fiberscope on the hemodynamic responses in ASA I patients. ⋯ Heart rate and arterial blood pressure (systolic BP, diastolic BP, mean ABP) were recorded before induction of Anaesthesia, 3 minutes after induction of Anaesthesia (before intubation) and 5 successive recordings at one-minute interval after intubation. All the systolic BP, diastolic Bp, mean ABP and heart rate values in the direct laryngoscopy group were significantly higher in the 5 successive minutes after intubation in comparison with the retromolar group (P = 0.00). This might be attributed to the gentle intubating technique, by the Bonfils retromolar fiberscope, which allows quick endotracheal intubation without manipulations of the base of the tongue or epiglottis.

Case ReportsLingual thyroid: a rare cause of difficult intubation.
This case report is about a patient with an oropharyngeal mass presenting to our hospital for biopsy under general anesthesia. Because of the great risk of failure of mask ventilation and direct laryngoscopy, an awake fiberoptic intubation was performed successfully. The biopsy revealed a thyroid tissue leading to the diagnosis of ectopic lingual thyroid.

The influence of simulation-based physiology labs taught by anesthesiologists on the attitudes of first-year medical students towards anesthesiology.
The development of medical students' perceptions of different medical specialties is based on many factors and influences their career choices and appreciation of other practitioners' knowledge and skills. The goal of this study was to determine if participation in a series of anesthesiologist-run, simulation-based physiology labs changed first year medical students' perceptions of anesthesiologists. ⋯ Using a survey instrument containing descriptors of different medical specialists and specialties, we found an improved attitude towards anesthesiology after medical students participated in an anesthesiologist-run simulation-based physiology lab series. Given the importance of providing high quality medical education and attracting quality applicants to the field, integrati-on of anesthesiology staff into medical student courses at the non-clinical level appears useful.
