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.

To assess the usefulness of the new NEMA (Neck Circumference Minus Acromion-Acromion Distance) parameter, in preoperative identification of patients' difficult intubation and compare it with other commonly used scales and tests. ⋯ It seems that none of the known bedside tests for predicting difficult intubation have a discriminating power sufficient for clinicians. Our study draws attention to a novel parameter, called NEMA, which appears to be a strong predictor of DEI, especially in combination with the Mallampati scale.

Comparative Study
The use of ultrasound in planned cesarean delivery under spinal anesthesia for patients having nonprominent anatomic landmarks.
The aim of the study was to compare conventional landmark method with ultrasound-guided spinal anesthesia in cesarean delivery cases where spinous processes and interspinous spaces were not prominent on physical examination. ⋯ Ultrasound guidance is an effective and safe method to reduce the number of puncture attempts, improve the success rate of subarachnoid access on the first attempt, and reduce the need to puncture multiple levels, although it prolongs procedure time in patients with score 2 according to our scoring system designed for this current study.

We report the application of ultrasound prescans for spinal anesthesia to morbid obesity patient. A 38-year-old woman with a body mass index (BMI) of 50 (weight: 110 kg; height: 148 cm) was scheduled to undergo pilonidal cyst resection at the bottom of the tailbone. Spinal anesthesia was selected for the procedure, because the patient's position during the surgery was prone and the patient had morbid obesity. ⋯ The transverse view of the patient's lumbar spine showed the posterior dura, transverse process, and posterior vertebral body below the thick fat tissue. At this point, spinal anesthesia was successfully performed. Pre-insertion ultrasound guidance for spinal anesthesia was useful in this morbidly obese patient with a BMI of 50.
