Meta Analysis Comparative Study
The ProSeal Laryngeal Mask Airway is more effective than the LMA-Classic in pediatric anesthesia: a meta-analysis.
To determine, in pediatric patients, whether the ProSeal Laryngeal Mask Airway (PLMA) has advantages over the LMA-Classic (cLMA) in leak pressure, placement difficulty, incidence of adverse events, postoperative blood staining, laryngospasm, bronchospasm, and hoarseness. ⋯ The PLMA (in sizes 1,1.5, 2, and 2.5) offers some advantages over the cLMA in pediatric anesthesia.

Review Case Reports
Intraoperative hypercyanosis in a patient with pulmonary artery band: case report and review of the literature.
A case of intraoperative cyanosis in a patient with a common atrioventricular canal palliated with a pulmonary artery (PA) band is presented. The patient's physiology was consistent with cyanosis due to inadequate pulmonary blood flow, and responded quickly to typical interventions used for a hypercyanotic episode in a patient with unrepaired Tetralogy of Fallot. Differences and similarities in the physiology of PA banding compared with Tetralogy of Fallot are presented, including a rationale for treatment options for hemodynamic decompensation occurring in the setting of anesthesia and surgery.

To evaluate the influence of insertion/deletion (ID) polymorphism of the angiotensin-converting enzyme (ACE) gene on clinical outcome of cardiac valve surgery. ⋯ ACE ID polymorphism is associated with a higher incidence of postoperative complications, including postoperative infections, in patients undergoing cardiac valve surgery.

Randomized Controlled Trial Comparative Study
Comparison of temporal artery, nasopharyngeal, and axillary temperature measurement during anesthesia in children.
To evaluate the accuracy and precision of a new, noninvasive infrared thermometer applied to the temporal artery. ⋯ The temporal artery thermometer is a substitute for the nasopharyngeal thermometer for core temperature measurement during anesthesia in children.

Review Comparative Study
Comprehensive review: is it better to use the Trendelenburg position or passive leg raising for the initial treatment of hypovolemia?
Hypovolemia is a common clinical problem. The Trendelenburg position and passive leg raising (PLR) are routinely used in the initial treatment while awaiting fluid resuscitation. In this meta-analysis, we evaluated the hemodynamic effects of PLR and Trendelenburg positioning to determine which position had the most optimal effect on cardiac output (CO). ⋯ The effect persisted after this period by 6%, or 0.17 L/min. Both Trendelenburg and PLR significantly increased CO, but only PLR seemed to sustain this effect after one minute. Although the Trendelenberg position is a common maneuver for nurses and doctors, PLR may be the better intervention in the initial treatment of hypovolemia.
