Review Meta AnalysisClinical safety and effectiveness of transversus abdominis plane (TAP) block in post-operative analgesia: a systematic review and meta-analysis.
Transversus abdominis plane (TAP) blocks can provide analgesia postoperatively for a range of surgeries. Abundant clinical trials have assessed TAP block showing positive analgesic effects. This systematic review assesses safety and effectiveness outcomes of TAP block in all clinical settings, comparing with both active (standard care) and inactive (placebo) comparators. ⋯ Postoperative pain within 24 h was reduced or at least equivalent in TAP block compared to its comparators. Therefore, TAP block is a safe and effective procedure compared to standard care, placebo and other analgesic techniques. Further research is warranted to investigate whether the TAP block technique can be improved by optimizing dose and technique-related factors.

Randomized Controlled TrialPopliteal block for lower limb surgery in children with cerebral palsy: effect on sevoflurane consumption and postoperative pain (a randomized, double-blinded, controlled trial).
The aim of this study was to evaluate the effects of a preoperative popliteal block on sevoflurane consumption, postoperative pain, and analgesic consumption in children with cerebral palsy (CP) following lower limb surgery. ⋯ Popliteal block is effective for postoperative analgesia, decreasing the paracetamol consumption and sevoflurane requirement in children with CP undergoing lower limb surgery. Trial registration ClinicalTrial.gov identifier: NCT02507700.

Case ReportsParavertebral block catheter breakage by electrocautery during thoracic surgery.
Advantages of thoracic paravertebral analgesia (TPA) include placement of the catheter closer to the surgical field; however, the catheter can become damaged during the operation. We experienced a case of intraoperative TPA catheter breakage that prompted us to perform an experiment to investigate possible causes. A 50-year-old male underwent a thoracoscopic lower lobectomy under general anesthesia with TPA via an intercostal approach. ⋯ In contrast, breakage occurred in only 3 and occlusion in none in the reinforced group, with the 5 without breakage remaining connected only by the spring coil. Furthermore, in 7 of the reinforced catheters, electric arc-induced thermal damage was observed at the tip of the catheter. A TPA catheter for thoracic surgery should be inserted via the median approach, or it should be inserted after surgery to avoid catheter damage during surgery.

Randomized Controlled Trial Comparative StudyComparison of ease of administration of intranasal midazolam spray and oral midazolam syrup by parents as premedication to children undergoing elective surgery.
The efficacy of midazolam as premedication in children for providing pre-operative sedation and reducing parental separation anxiety has been well established. Many studies have compared the effectiveness and medication acceptance of midazolam via oral and intranasal routes. In this study, we have compared the ease of administration of oral midazolam syrup and intranasal midazolam spray as premedication, administered by parents to children. ⋯ Oral midazolam syrup is easier for parents to administer and has better medication acceptance in children when compared to intranasal midazolam spray.
