Randomized Controlled Trial Clinical TrialThe effects of two rewarming strategies on heat balance and metabolism after coronary artery bypass surgery with moderate hypothermia.
Postoperative hypothermia is common in cardiac surgery with hypothermic cardiopulmonary bypass (CPB). This trial was designed to evaluate whether rewarming over the normal bladder temperature (over 37 degrees C) at the end of hypothermic CPB combined with passive heating methods after CPB might result in a better heat balance, lower energy expenditure (EE) and decrease of disturbances in oxygen balance compared to only rewarming the patients to a bladder temperature of 35-37 degrees C. ⋯ With rewarming the patients at the end of CPB to a bladder temperature of over 37 degrees C combined with passive heating methods after CPB, it was possible to decrease EE and VO2 compared to the control group (rewarmed to bladder temperature of 35-37 degrees C) after coronary artery bypass surgery with moderate hypothermia.

Randomized Controlled Trial Clinical TrialThe pressor response after laryngeal mask or cuffed oropharyngeal airway insertion.
Since the cuffed oropharyngeal airway (COPA) has been suggested to cause less pharyngeal trauma than the laryngeal mask airway (LMA), we conducted a prospective, randomised study to compare haemodynamic changes after placing either the COPA or LMA in healthy anaesthetised adults. ⋯ In healthy, anaesthetised patients, placing a cuffed oropharyngeal airway is associated with smaller cardiovascular changes after airway insertion compared with the laryngeal mask airway.

Effects of intrathecal morphine, clonidine and baclofen on allodynia after partial sciatic nerve injury in the rat.
Increased response to mechanical or cold stimulation of hind paws was observed in rats with partial sciatic nerve injury as a result of photochemically induced ischemia. The present study examined the effects of intrathecal morphine, clonidine and baclofen on the allodynia-like responses. ⋯ The present data suggest that intrathecal morphine, and to some extent clonidine, but not baclofen, alleviated the abnormal pain-related behaviors in this new rat model of partial peripheral nerve injury. Differences in the pharmacological profile between the present model and other models of peripheral nerve injury are discussed.
