[Does ultrasonographic volume of the thyroid gland correlate with difficult intubation? An observational study].
Preoperative ultrasonographic evaluation of the thyroid gland done by surgeons could let us foresee airway management challenges. The aim of this observational study was to evaluate the effects of thyroid-related parameters assessed preoperatively by surgeons via ultrasonography and chest X-ray on intubation conditions. ⋯ The thyroid volume is not associated with difficult intubation. However clinical assessment parameters may predict difficult intubation.

[Evaluation of brachial plexus fascicles involvement on infraclavicular block: unfixed cadaver study].
This study shows how occurs the diffusion of the anesthetic into the sheath through the axiliary infraclavicular space and hence prove the efficacy of the anesthetic block of the brachial plexus, and may thereby allow a consolidation of this pathway, with fewer complications, previously attached to the anesthesia. ⋯ The results allow us to establish the infraclavicular as an effective and easy way to access plexus brachial, because the solution involved the fascicles in 81.76% partially or totally, when was injected inside the axillary sheath. We believe that only the use of this pathway access in practice it may demonstrate the efficiency.

[Effect of intraoperative esmolol infusion on anesthetic, analgesic requirements and postoperative nausea-vomitting in a group of laparoscopic cholecystectomy patients].
Postoperative pain and nausea/vomitting (PNV) are common in laparoscopic cholecystectomy patients. Sympatholytic agents might decrease requirements for intravenous or inhalation anesthetics and opioids. In this study we aimed to analyze effects of esmolol on intraoperative anesthetic-postoperative analgesic requirements, postoperative pain and PNV. ⋯ Using esmolol during anesthetic maintenance significantly decreases anesthetic-analgesic requirements, postoperative pain and PNV.

[Clinical application of thoracic paravertebral anesthetic block in breast surgeries].
optimum treatment for postoperative pain has been of fundamental importance in surgical patient care. Among the analgesic techniques aimed at this group of patients, thoracic paravertebral block combined with general anesthesia stands out for the good results and favorable risk-benefit ratio. Many local anesthetics and other adjuvant drugs are being investigated for use in this technique, in order to improve the quality of analgesia and reduce adverse effects. ⋯ thoracic paravertebral block reduced postoperative analgesic requirement compared to placebo group, markedly within the first 24hours. The use of this technique could ensure postoperative analgesia of clinical relevance. Further studies with larger populations are necessary, as paravertebral block seems to be promising for preemptive analgesia in breast cancer surgery.

[Effect of intraoperative intravenous lidocaine on pain and plasma interleukin-6 in patients undergoing hysterectomy].
Interleukin-6 (IL-6) is a predictor of trauma severity. The purpose of this study was to evaluate the effect of intravenous lidocaine on pain severity and plasma IL-6 after hysterectomy. ⋯ Intravenous lidocaine (2mg.kg(-1).h(-1)) did not reduce pain severity and plasma levels of IL-6 in patients undergoing abdominal hysterectomy.
