Comparative Study
Cardiovascular magnetic resonance is successfully feasible in many patients aged 3 to 8years without general anesthesia or sedation.
Patients younger than 8 years are usually examined by cardiovascular magnetic resonance (CMR) under general anesthesia (GA) or sedation without intubation. Therefore, we sought to study the feasibility of CMR in patients aged 3 to 8years without GA or sedation. ⋯ CMR in patients aged 3 to 8years is usually successfully feasible without GA or sedation.

The effect of serratus plane block performed under direct vision on postoperative pain in breast surgery.
To determine the effectiveness of serratus plane block performed under direct vision on postoperative pain after mastectomy. ⋯ Serratus block provides effective regional anesthesia, suitable for mastectomies, and currently appears to be superior to wound infiltration alone. However, further data will need to be collected to support this finding.

Observational Study
Pulse oximetry-derived pleth variability index can predict dexmedetomidine-induced changes in blood pressure in spontaneously breathing patients.
Hypertension or hypotension in patients receiving continuous infusions of dexmedetomidine (DEX) is often due to changes in vascular resistance caused by α2 receptor stimulation. We investigated whether baseline perfusion index (PI) and pleth variability index (PVI), derived from pulse oximetry readings, could predict DEX-induced changes in the hemodynamic status in spontaneously breathing patients. ⋯ PVI may predict DEX-induced changes in blood pressure in spontaneously breathing patients.

To find the position that provided the most comfort, as well as the widest L3-L4 interlaminar space opening. ⋯ Ultrasonographic measurements carried out on 32 subjects showed that "sitting fetal," "lying fetal," and "hugging a ball" positions provided the widest L3-L4 interlaminar openings. These 3 positions were also found to be more comfortable.
