Comparative StudyThe accuracy of bioimpedance cardiography in the measurement of cardiac output in comparison with thermodilution method.
Continuous noninvasive measurement of cardiac output (CO) is clinically desirable. Thoracic electrical bioimpedance (TEB) offers such a continuous noninvasive technique for the measurement of CO on a beat-by-beat basis. The purpose of this study was to compare the correlation of TEB with the thermodilution (TD) method of measuring CO during surgery. ⋯ Technological advances in TEB have resulted in more accurate CO measurements. Such device offers a noninvasive alternative to the TD technique for the determination of CO, and may potentially be very useful as a powerful, noninvasive, continuous technique for monitoring cardiac function in the clinical setting.

Randomized Controlled Trial Comparative Study Clinical TrialA comparison of lidocaine, fentanyl, and esmolol for attenuation of cardiovascular response to laryngoscopy and tracheal intubation.
Laryngoscopy and tracheal intubation are known to increase sympathetic activity that may be detrimental to patients with pre-existing ischemic or hypertensive heart diseases. In order to alter the hyperdynamic consequences resulting from intubation during induction of general anesthesia, we chose esmolol, an ultra-short acting cardioselective beta-adrenergic blocker, to attenuate the cardiovascular responses during tracheal intubation in patients undergoing elective surgery. The efficacy of esmolol in this regard was carefully evaluated. ⋯ Results of this study showed that only esmolol could reliably offer protection against the increase in both HR and SBP, low dose of fentanyl (3 micrograms/kg) prevented hypertension but not tachycardia, and 2 mg/kg lidocaine had no effect to blunt adverse hemodynamic responses during laryngoscopy and tracheal intubation.

Randomized Controlled Trial Clinical Trial[Pre- and intra-operative administration of epidural morphine provides good postoperative pain relief after laminectomy].
To evaluate the postoperative analgesic effect of epidural morphine administered at different timing in lumbar spine surgery. ⋯ Preoperative or intraoperative administration of epidural morphine could provide satisfactory analgesia in lumbar spine surgery during the first 24 h postoperatively.

Case ReportsPropofol anesthesia in a patient with myasthenia gravis--a case report.
Experience with the use of propofol for induction and maintenance of anesthesia in patients with myasthenia gravis is limited in the literature. We report, in this case, the well prepared and successful use of continuous propofol infusion without conventional neuromuscular blocking agents in a patient with Ossermann stage IIb of myasthenia gravis undergoing laparoscopic cholecystectomy.

Case ReportsRecurrent epistaxis following nasotracheal intubation--a case report.
Epistaxis is one of the common complications of nasotracheal intubation. Clinical patterns of all nasal bleeding are mild and may stop spontaneously in most patients. Serious nasal bleeding requiring hospitalization are rare. ⋯ Although numerous publications have reported the cases of initial epistaxis caused by nasotracheal intubation, recurrent epistaxis was reported rarely. We experienced a case of recurrent epistaxis occurring in the 6th, 8th, 15th and 18th day after nasotracheal intubation. Herein, we describe the clinical events and discuss the causes of epistaxis.
