[Analgesia Nociception Index for perioperative analgesia monitoring in spinal surgery].
The Analgesia Nociception Index is an index used to measure the levels of pain, sympathetic system activity and heart rate variability during general anesthesia. In our study, Analgesia Nociception Index monitoring in two groups who had undergone spinal stabilization surgery and were administered propofol-remifentanil (Total Intravenous Anesthesia) and sevoflurane-remifentanyl anesthesia was compared regarding its significance for prediction of postoperative early pain. ⋯ Analgesia Nociception Index is a valuable parameter for monitoring of perioperative and postoperative analgesia. In spine surgery, similar analgesia can be provided in both Total Intravenous Anesthesia with remifentanil and sevoflurane administration. Analgesia Nociception Index is efficient for prediction of the need for analgesia during the early postoperative period, and therefore is the provision of patient comfort.

Case Reports[Tension pneumothorax during peroral endoscopic myotomy for treatment of esophageal achalasia under general anesthesia].
More and more endoscopically gastrointestinal procedures require anesthesiologists to perform general anesthesia, such as "peroral endoscopic myotomy". Peroral endoscopic myotomy is a novel invasive treatment for the primary motility disorder of esophagus, called esophageal achalasia. Despite of its minimally invasive feature, there are still complications during the procedure which develop to critical conditions and threat patients' lives. ⋯ The emergent management of the complication is stated in detail. The pivotal points of general anesthesia for patients undergoing peroral endoscopic myotomy are emphasized and discussed. Also, intraoperative and post-operative complications mentioned by literature are integrated.

Case Reports[Ultrasound guided quadratus lumborum block for analgesia after cesarean delivery: case series].
The majority of women having planned cesarean section receive spinal anesthesia for the procedure. Typically, spinal opioids are administered during the same time as a component of multimodal analgesia to provide pain relief in the 16-24h period postoperatively. The quadratus lumborum block is a regional analgesic technique that blocks T5-L1 nerve branches and has an evolving role in postoperative analgesia for lower abdominal surgeries and may be a potential alternative to spinal opioids. If found effective, it will have the advantage of a reduction in opioid associated adverse effects while providing similar quality of analgesia. ⋯ Quadratus lumborum block may be a promising anesthetic adjuvant for post-cesarean analgesia. Further randomized controlled trials are needed to compare the efficacy of the quadratus lumborum block with intrathecal opioids.

[Ultrasound-guided central venous catheterization - "Syringe-Free" approach].
Central venous catheterization of the internal jugular vein is a commonly performed invasive procedure associated with a significant morbidity and even mortality. Ultrasound-guided methods have shown to improve significantly the success of the technique and are recommended by various scientific societies, including the American Society of Anesthesiologists. The aim of this report is to describe an innovative ultrasound-guided central line placement of the internal jugular vein. ⋯ The described method adds to the traditional oblique technique the possibility of achieving a continuous real-time ultrasound-guided venipuncture and a guide wire insertion that does not need removing the probe from the puncture field, while having a single operator performing the whole procedure.

Case Reports[Sphenopalatine ganglion block for postdural puncture headache in ambulatory setting].
Postdural puncture headache (PDPH) is a common complication following subarachnoid blockade and its incidence varies with the size of the needle used and the needle design. Supportive therapy is the usual initial approach. Epidural blood patch (EBP) is the gold-standard when supportive therapy fails but has significant risks associated. Sphenopalatine ganglion block (SPGB) may be a safer alternative. ⋯ SPGB may attenuate cerebral vasodilation induced by parasympathetic stimulation transmitted through neurons that have synapses in the sphenopalatine ganglion. This would be in agreement with the Monro-Kellie concept and would explain why caffeine and sumatriptan can have some effect in the treatment of PDPH. Apparently, SPGB has a faster onset than EBP with better safety profile. We suggest that patients presenting with PDPH should be considered primarily for SPGB. Patients may have a rescue EBP if needed.
