Randomized Controlled TrialOptimal fentanyl dosage for attenuating systemic hemodynamic changes, hormone release and cardiac output changes during the induction of anesthesia in patients with and without hypertension: a prospective, randomized, double-blinded study.
The purpose of this study was to compare the dose-related effects of fentanyl on systemic hemodynamics, hormone release and cardiac output in response to endotracheal intubation in patients with and without hypertension. ⋯ The present study shows that it is preferable to administer 2 μg/kg fentanyl in patients without hypertension and 4 μg/kg fentanyl in patients with hypertension in order to minimize the changes in heart rate, systolic blood pressure and cardiac output associated with tracheal intubation.

Randomized Controlled TrialA novel method for SLIPA™ size selection, for adult patients, on the basis of chamber length.
Nowadays the size of the streamlined liner of the pharynx airway (SLIPA™) is selected by matching the width of the thyroid cartilage of the patient to the widest dimension of the SLIPA™. The objective of this work was to improve the method of selection by matching the distance between the otobasion inferius and the most inferior margin of the cricoid cartilage (O-C) to the length of the SLIPA™ chamber. ⋯ Compared with the classic size-selection method, matching the width of the thyroid cartilage with that of the SLIPA™, the size-selection method of matching SLIPA™ chamber length to O-C for adult patients is more accurate.

Randomized Controlled Trial Clinical TrialThe effects of anesthetic technique and ambient temperature on thermoregulation in lower extremity surgery.
The purpose of our study was to determine the effects of anesthetic technique and ambient temperature on thermoregulation for patients undergoing lower extremity surgery. ⋯ There were no significant differences in thermoregulation among anesthetic techniques. Room temperature affected thermoregulation in Group GA.

Randomized Controlled TrialEffect of palonosetron on postanesthetic shivering after propofol-remifentanil total intravenous anesthesia.
The authors conducted a prospective, randomized, double-blind study to evaluate the anti-shivering efficacy of palonosetron for patients after gynecological laparoscopy under total intravenous propofol-remifentanil anesthesia. ⋯ Use of palonosetron (0.075 mg) did not reduce the incidence of postanesthetic shivering after gynecological laparoscopy under propofol-remifentanil anesthesia. Further study including other 5-HT3 antagonists or male patients would elucidate the effect of palonosetron on shivering after propofol-remifentanil anesthesia.

Randomized Controlled TrialA pilot study to compare epidural identification and catheterization using a saline-filled syringe versus a continuous hydrostatic pressure system.
We are introducing a new continuous hydrostatic pressure system for identification and catheterization of epidural space in adults. One hundred and eight patients scheduled for elective endoscopic urological procedures were enrolled in this prospective randomized study. They were assigned to perform loss of resistance epidural technique by either the conventional saline-filled syringe (group C) or the new pressure technique (group P). ⋯ Significant reduction was found in group P versus group C concerning time to identify epidural space [20 (6-40) vs. 60.5 (23-75) s with p = 0.001], number of attempts [1 (1-2) vs. 1 (1-4) with p = 0.02] and motor block [1 (0-3) vs. 2 (0-2) with p = 0.02], respectively. No significant difference in epidural catheterization, sensory block, quality of anesthesia and incidence of side effects. We concluded that this new technique is an easy way to identify epidural space using available tools in the operating room.
