[Bilateral mandibular nerve injury following mask ventilation: a case report].
Nerve injury following mask ventilation is a rare but serious anesthetic complication. The majority of reported cases are associated with excessive pressure applied to the face mask, long duration of mask ventilation, excessive digital pressure behind the mandible to relieve airway obstruction and pressure exerted by the plastic oropharyngeal airway. ⋯ An over-inflated sealing cushion of a facemask may trigger difficult mask ventilation leading to mandibular nerve injury following mask ventilation. Alternative airway management techniques such as laryngeal mask airway should be considered when airway maintenance can only be achieved with strong pressure applied to the facemask and/or mandible.

[The influence of the menstrual cycle on acute and persistent pain after laparoscopic cholecystectomy].
Fluctuations of female sex hormones during menstrual cycle influence pain perception. Endogenous pain inhibition is impaired in follicular phase of menstrual cycle. We tested the primary hypothesis that the women having surgery during their follicular phase have more acute pain and require higher opioids than those in the luteal phase, and secondarily we tested that women who have surgery during their follicular phase have more incisional pain at 3 month postoperatively. ⋯ Although persistent postoperative pain was significantly more common one and three months after surgery the magnitude of the pain was low. Our results do not support scheduling operations to target particular phases of the menstrual cycle.

[Effect of table tilt and spine flexion-rotation on the acoustic window of the lumbar spine in pregnant women].
The purpose of this study was to assess whether application of dorsal table tilt and body rotation to a parturient seated for neuraxial anesthesia increased the size of the paramedian target area for neuraxial needle insertion. ⋯ These data show that the positions studied did not increase the target area as defined by the length of the posterior longitudinal ligament for the purpose of neuraxial needle insertion in obstetric patients. The maneuvers studied will have limited use in improving spinal needle access in pregnant women.

[Dural sinus thrombosis following epidural analgesia for delivery: a clinical case].
Neurological complications of spinal anesthesia are rare conditions. Headache caused by low pressure of the cerebrospinal fluid is one of the most frequent, which occurs after post-dural puncture. A comprehensive history and physical exam must be carried out before making the diagnosis of Post-Dural Puncture Headache (PDPH) and additional tests are necessary to exclude the possibility of developing serious neurological complications such as Dural Sinus Thrombosis (DST). According to the Case Report a differential diagnosis between Dural Sinus Thrombosis with PDPH is discussed. ⋯ The report describes a patient who developed severe headache following continuous epidural analgesia for delivery. Initially it was diagnosed as PDPH, however with the aid of an MRI the diagnosis of TSD was later established and treated. TSD is a rare condition and is often underdiagnosed. Because of its potentially lethal complications, it should always be considered in acute headache differential diagnosis.

[Effect of video-based education on anxiety and satisfaction of patients undergoing spinal anesthesia].
Providing sufficient information during a preanesthetic interview may help improve patient understanding and decrease anxiety related to spinal anesthesia. We investigated the effect of video-based education on anxiety and satisfaction in patients about to undergo spinal anesthesia. ⋯ Providing video-based information during the preanesthetic interview alleviated anxiety and increased satisfaction in patients undergoing spinal anesthesia.
