Randomized Controlled TrialRetrolaminar block: analgesic efficacy and safety evaluation.
Retrolaminar block (RLB) is a thoracic truncal block that can produce analgesia for the thoracic and abdominal wall. However, the characteristics of RLB are not well known. The aim of this study was to determine analgesic efficacy by measuring postoperative consume of patient-controlled analgesia (PCA), additional nonsteroidal antiinflammatory drug (NSAID) rescue, and opioid rescue. Our secondary analysis included assessment of the chronological change in arterial levobupivacaine concentrations after the block. ⋯ Continuous RLB was not inferior to PVB except for the first 24 h, and was satisfactory after mastectomy. RLB showed safe, low peak arterial levobupivacaine concentrations.

Randomized Controlled TrialThe effects of intravenous anesthetics on QT interval during anesthetic induction with sevoflurane.
Sevoflurane is known to prolong the QT interval. This study aimed to determine the effect of the interaction between intravenous anesthetics and sevoflurane on the QT interval. ⋯ We concluded that an injection of propofol could counteract QTc interval prolongation associated with sevoflurane anesthesia induction.

Randomized Controlled TrialAnalgesic effect of a single dose of betamethasone after ambulatory knee arthroscopy: a randomized controlled trial.
Glucocorticoids are reported to improve postoperative analgesia. The purpose of the study was to investigate whether a preoperative, single dose of betamethasone could reduce pain after ambulatory arthroscopic knee surgery. ⋯ An analgesic benefit was seen day 1 following surgery. This indicates that betamethasone has a place in ambulatory arthroscopic knee surgery.

Randomized Controlled TrialEffects of oral carbohydrate with amino acid solution on the metabolic status of patients in the preoperative period: a randomized, prospective clinical trial.
Enhanced recovery after surgery is increasingly desired nowadays, and preoperative nutrient intake may be beneficial for this purpose. In this study, we investigated whether the intake of preoperative carbohydrate with amino acid (ONS) solution can improve starvation status and lipid catabolism before the induction of anesthesia. ⋯ The results of this study suggest that preoperative ONS intake improves lipid catabolism and starvation status before the induction of anesthesia. Furthermore, it can provide better preoperative mental health compared with complete fasting.

Randomized Controlled TrialThe efficacy of simultaneous bilateral axillary brachial plexus block under the guidance of neurostimulator or ultrasound: a prospective study.
This study was designed to investigate the risk of local anesthetic toxicity and efficacy of simultaneous bilateral axillary brachial plexus block performed under the guidance of ultrasound or a neurostimulator. ⋯ Simultaneous bilateral axillary brachial plexus block guided by neurostimulator or ultrasound in bilateral distal upper extremity surgery seems to have a low risk of local anesthetic toxicity and to be effective. The ultrasound-guided block is superior in terms of providing the same degree of anesthesia with shorter duration, less pain, and faster onset of sensory and motor blockades, which is important in clinical practice.
