Randomized Controlled Trial Comparative Study[Rotational thromboelastometry assessment of ballanced crystalloid, hydroxyethyl starch and gelatin effects on coagulation: a randomized trial].
Modern crystalloid and colloid solutions are balanced solutions which are increasingly used in perioperative period. However, studies investigating their negative effect on whole blood coagulation are missing, and vivid debate is going on about which solution has the minimal coagulopathy effect. The aim of our study was to assess the effect of modern fluid solutions on whole blood coagulation using rotational thromboelastometry. ⋯ Extem test appears to be sensitive to coagulopathy effect of modern colloids and crystalloids. Hydroxyethyl starch has the most obvious negative effect on clot formation followed by gelatin and finally by crystalloids. Intem test seems to be insensitive to adverse effect of modern colloids and crystalloids.

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.

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.

Case Reports[Ultrasound guided erector spinae plane block for postoperative analgesia after augmentation mammoplasty: case series].
Augmentation mammoplasty is the third most frequently performed esthetic surgical procedure worldwide. Breast augmentation with prosthetic implants requires the insertion of an implant under breast tissue, which causes severe pain due to tissue extension and surgical trauma to separated tissues. In this case series, we present the successful pain management of six patients with ultrasound-guided Erector Spinae Plane block after augmentation mammoplasty. ⋯ At the postoperative 24th hour, the mean Numerical Rating Scale score was 1. The mean intravenous tramadol consumption was 70.8±15.3mg in the first 24 h. None of the patients had any complications related to erector spinae plane block.

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.
