Randomized Controlled Trial Clinical Trial
External rewarming and age in mildly hypothermic patients after cardiac surgery.
To compare the effects of two external rewarming methods on body core temperature and the rate of rewarming between two age groups (less than 65 years, 65 years or more) of adult, mildly hypothermic patients who have undergone cardiac surgery, during the immediate postoperative period. ⋯ In this study, conduction and reflection of radiant heat were equally effective in producing an acceptable rate of rewarming but contributed to different internal patterns in core rewarming. The average total rewarming time with the active external rewarming method was 1 hour shorter than with the passive external rewarming method.

Randomized Controlled Trial Clinical Trial
The effects of music interventions on anxiety in the patient after coronary artery bypass grafting.
To examine the influence during the early postoperative period of selected nursing interventions on mood and anxiety of patients undergoing heart surgery. ⋯ Although none of the three interventions was overwhelmingly superior, the overall response by all intervention groups demonstrated a generalized relaxation response. It is also important to note that there was reduced anxiety and improved mood within all three groups.

Randomized Controlled Trial Comparative Study Clinical Trial
A comparison of the effects of assist-control, SIMV, and SIMV with pressure support on ventilation, oxygen consumption, and ventilatory equivalent.
To quantify the ventilatory efficiency of different modes of mechanical ventilation used to achieve full ventilatory support in normal subjects. Modes compared were assist-control, synchronized intermittent mandatory ventilation (SIMV), and SIMV with 10 cm H2O (0.98 kPA) of pressure support. ⋯ SIMV with pressure support significantly increased minute volume and ventilatory equivalent when compared with assist-control or SIMV alone, and thus was the most efficient mode of full ventilatory support for our subjects. We found no difference in ventilatory efficiency between assist-control and SIMV. All three mechanical modes were less efficient for our subjects than spontaneous breathing. The inspiratory time of 1 second used in this study, although common in clinical practice, may be inadequate for some patients.

Randomized Controlled Trial Comparative Study Clinical Trial
Managing pain during mediastinal chest tube removal.
To compare four analgesic regimens used in preparing patients for chest tube removal. ⋯ Blind ratings of subjects' descriptions of sensations suggest subfascial lidocaine may be useful in reducing discomfort during chest tube removal.

Randomized Controlled Trial Comparative Study Clinical Trial
Accuracy of infrared ear thermometry and traditional temperature methods in young children.
To compare the accuracy of ear-based, rectal, and axillary temperature measurements in comparison to bladder temperature as a core reference. ⋯ The findings suggest that the additive core-mode adjustments in infrared ear thermometers are too low for young children, an ear tug is not an essential part of measurement technique, rectal temperature closely reflects bladder temperature, and axillary temperature is low and highly variable.
