Case Reports[Do we still need central blocks while we have erector spinae plane block? Case of 2.5 month old infant].
Erector spinae plane block is gaining popularity both for its ease of application and as its comparable effect on postoperative analgesia with central regional techniques like paravertebral block or epidural anesthesia. Its use for many indications has been reported in the literature for pediatric patients. ⋯ No complication was seen during both surgery and follow up period. Erector spinae plane block with the combination of paracetamol was adequate for pain relief.

Observational Study[Evaluation of Bispectral Index time delay in response to anesthesia induction: an observational study].
According to the manufacturer, the Bispectral Index (BIS) has a processing time delay of 5-10s. Studies addressing this have suggested longer delays. We evaluated the time delay in the Bispectral Index response. ⋯ Our results may be another indication that the delay in BIS processing may be much longer than stated by the manufacture, a fact with clinical implications.

[Ultrasound assessment of gastric antrum in term pregnant women before elective cesarean section].
Pregnant women are considered patients at risk for pulmonary aspiration of gastric contents. The study aim was to evaluate the gastric antral cross-sectional area using ultrasound. ⋯ Measuring the gastric antral cross-sectional area of pregnant women is feasible and easy. There was positive correlation between gastric antral cross-sectional area, body weight and body mass index. The estimation of gastric volume by measuring the gastric antral cross-sectional area can identify patients at risk for pulmonary aspiration. Obese patients had a gastric antral cross-sectional area and an estimated gastric volume greater than non-obese patients.

Case Reports[Delayed trigeminocardiac reflex after maxillofacial surgery: case report].
Trigeminocardiac reflex is a physiological phenomenon that may occur in head and neck surgery, and is usually benign. However, it may present with exaggerated responses with severe morbidity. ⋯ Trigeminocardiac reflex may be a protective neurogenic, oxygen-conserving response with low morbidity, however, exacerbated in certain situations. The interaction between surgeon and anesthesiologist, together with a careful monitoring of blood pressure and heart rate are fundamental for diagnosis and treatment.

Randomized Controlled Trial Comparative Study[Comparison of adductor canal block for analgesia in arthroscopic surgery with ropivacaine alone and ropivacaine and clonidine].
Inadequate pain relief after anterior cruciate ligament reconstruction affects mobility leading to development of adhesions, weakened ligament insertion and muscle atrophy. Adductor canal block for postoperative analgesia preserves quadriceps strength. The present study was conducted to compare pain free period in patients undergoing arthroscopic anterior cruciate ligament reconstruction, receiving ultrasound-guided adductor canal block with ropivacaine alone and ropivacaine with clonidine. ⋯ Addition of clonidine to ropivacaine in USG guided adductor canal block led to significant prolongation of pain free period though pain score at rest and movement, and rescue analgesic requirement, did not differ.
