Randomized Controlled TrialComparison of bolus remifentanil versus bolus fentanyl for blunting cardiovascular intubation responses in children: a randomized, double-blind study.
The authors found no study to compare the efficacy of bolus dose fentanyl and remifentanil blunting the cardiovascular intubation response in children, so they designed this randomized, double-blind clinical study to assess the effects of remifentanil 2 microg/kg and fentanyl 2 microg/kg by bolus injection on the cardiovascular intubation response in healthy children. ⋯ When used as part of routine anesthesia induction with propofol and vecuronium in children, fentanyl 2 microg/kg by bolus injection fails to effectively depress the cardiovascular intubation response. Remifentanil 2 microg/kg by bolus injection can completely abolish the cardiovascular intubation response, but also cause more adverse complications of temporary significant cardiovascular depression.

Randomized Controlled Trial Multicenter StudyCharacteristics of the Chinese subjects entered the hypertension in the very elderly trial.
The baseline characteristics of patients in a multinational trial are possibly related to cardiovascular outcome. This study compared the baseline characteristics of patients recruited in China with those recruited in other countries. ⋯ Calorie restriction, compared with the rest of the world, may have resulted in lower stature and weight, and recent increases in calorie intake have not changed the metabolic profile of the very elderly hypertensive patients in China. Some of these biochemical differences may reflect different dietary lifestyle in the Chinese.

Randomized Controlled Trial Comparative StudyCirculatory responses to nasotracheal intubation: comparison of GlideScope videolaryngoscope and Macintosh direct laryngoscope.
The GlideScope videolaryngoscope (GSVL) has been shown to have no special advantage over the Macintosh direct laryngoscope (MDL) in attenuating the circulatory responses to orotracheal intubation, but no study has compared the circulatory responses to nasotracheal intubation (NTI) using the two devices. This prospective randomized clinical study was designed to determine whether there was a clinically relevant difference between the circulatory responses to NTI with the GSVL and the MDL. ⋯ The pressor response to NTI with the GSVL and the MDL was similar, but the tachycardiac response to NTI was lesser and of a shorter duration when using a GSVL than when using an MDL.

Randomized Controlled TrialSalmon calcitonin in prevention of osteoporosis in maintenance dialysis patients.
Renal osteodystrophy is one of the commonest complications of chronic renal failure. It may have a severe impact on the quality of life of patients on maintenance dialysis therapy. Besides post-menopausal women and elderly people, the dialysis patients are another high risk group. But at present, there is no research on how to prevent osteoporosis in maintenance dialysis patients. This study was conducted to observe the bone density of maintenance dialysis patients and to evaluate the clinical outcomes and safety of different administration dosage of salmon calcitonin to prevent osteoporosis in maintenance dialysis patients. ⋯ The dose of salmon calcitonin 50 U three times a week plus calcium carbonate and active vitamin D can effectively preserve the BMD and prevent bone loss in maintenance dialysis patients, and it is well tolerated by patients on maintenance dialysis.
