Fiberoptical assisted intubation via a placed laryngeal mask airway (LMA) has been described as save and easy procedure to manage a difficult airway. The laryngeal tube (LT) is a promising alternative to the LMA as supraglottic airway device. Fiberoptical assisted intubation via LT is possible, however considered more difficult. The aim of this study was to compare the fiberoptical assisted intubation via LT and LMA. ⋯ A fiberoptical assisted intubation via LT can be considered as a relevant alternative in advanced airway management.

0.5% levobupivacaine versus 0.5% ropivacaine: Are they different in ultrasound-guided sciatic block?
Little is known about onset and duration of sciatic block after 0.5% levobupivacaine (Levo) versus 0.5% ropivacaine (Ropi) for ultrasound-guided technique. We assessed these parameters in the ultrasound-guided block, to know for the practice. ⋯ No difference of onset times was found in ultrasound-guided sciatic block whether using Levo or Ropi. Levo induced a longer-lasting sensory block.

Procedural discomfort is experienced by patients during the establishment of subarachnoid block even after good preoperative counseling and adequate premedication. To enhance comfort, procedural sedation that would provide good analgesia, faster recovery, and amnesia is necessary. ⋯ Ketamine in the dose of 0.3 mg/kg provided sufficient sedation for allaying procedural discomfort due to less sedation, less positional difficulty, early verbal response, no hallucinations, no recall of performance of procedure, and good patient satisfaction.

Quantification of the depth of desflurane anesthesia required for laryngeal mask airway (LMA) removal in children has been done with the use of intravenous fentanyl or caudal anesthesia. This study aimed to determine the end-tidal concentration of desflurane required for LMA removal in children without the use of caudal or opioid analgesia in children undergoing elective cataract surgery. ⋯ Laryngeal mask airway removal can be successfully accomplished in 50% and 95% anesthetized children at 3.6% and 4.65% end-tidal desflurane concentration.
