Comparative Study
Awake tracheal intubation in anticipated difficult airways: LMA Fastrach vs flexible bronchoscope: A pilot study.
To compare the use of LMA Fastrach intubating laryngeal mask airway (ILMA) to flexible bronchoscopy (FB) for awake intubation in patients with difficult airways. ⋯ Awake intubation can be performed successfully and expeditiously with the use of LMA Fastrach in patients with a difficult airway and no contraindication to a blind technique. It compared favorably to the use of the fiberoptic bronchoscope in the patient cohort presented in this study.

Randomized Controlled Trial
The concentration of desflurane preventing spectral entropy change during surgical stimulation: A prospective randomized trial.
To determine the concentration of desflurane necessary to blunt changes in spectral entropy during surgical incision when two different target-controlled effect-site concentrations of remifentanil (1 and 3ng/ml) were infused. ⋯ Desflurane 4.1% with remifentanil 1ng/ml and desflurane 3.4% with remifentanil 3ng/ml significantly blunt the change in spectral entropy after surgical incision in 50% of patients.

Comparative Study Clinical Trial
Cardiac output changes with phenylephrine and ephedrine infusions during spinal anesthesia for cesarean section: A randomized, double-blind trial.
Hypotension is a common side effect of spinal anesthesia. Phenylephrine and ephedrine are the two most frequently used vasopressors to treat spinal hypotension during cesarean delivery. In this randomized double-blind study, we aimed to evaluate cardiac output (CO) changes with phenylephrine or ephedrine infusions titrated to maintain baseline systolic blood pressure (bSBP) during spinal anesthesia. ⋯ The maximum increase in CO from the baseline was 12%, in the ephedrine group, and this occurred 20 minutes after spinal injection. Cardiac output fell by more than 17% in the phenylephrine group, maximal at 10 minutes following spinal injection. Despite good systolic blood pressure control and increased cardiac output with ephedrine, administration of ephedrine was associated with significantly more fetal acidosis [Median (Interquartile range, IQR) UApH - phenylephrine = 7.33 (7.31-7.34) and ephedrine = 7.22 (7.16-7.27), P < .05].

Comparative Study Clinical Trial
Dexmedetomidine decreases the required amount of bupivacaine for ultrasound-guided transversus abdominis plane block in pediatrics patients: a randomized study.
The effect of dexmedetomidine on the potency of bupivacaine for transversus abdominis plane (TAP) block in pediatric patients has not been investigated. ⋯ The addition of 2μg/kg of dexmedetomidine reduced the minimum local anesthetic concentration of bupivacaine used for a TAP block and improved postoperative analgesia in children undergoing surgery for inguinal hernia repair or hydrocelectomy.

Randomized Controlled Trial
The effect of play distraction on anxiety before premedication administration: a randomized trial.
The majority of children scheduled to undergo surgery experience substantial anxiety in the preoperative holding area before induction of anesthesia. Pharmacological interventions aimed at reducing perioperative anxiety are paradoxically a source of stress for children themselves. Midazolam is frequently used as premedication, and the formula of this drug in Turkey is bitter. We aimed to assess the role of distraction in the form of playing with play dough (Play-Doh) on reducing premedication anxiety in children. ⋯ This study showed that distraction in the form of playing with play dough facilitated administration of oral midazolam in young children.
