Intrathecal clonidine prolongs spinal anesthesia but the optimum dose to be used in cesarean delivery is not yet known. We evaluated the effect of addition of intrathecal clonidine to hyperbaric bupivacaine on postoperative pain after lower segment caesarean section. ⋯ Addition of 75 μg clonidine to hyperbaric bupivacaine in spinal anesthesia for LSCS significantly prolongs the duration of postoperative analgesia without any increase in maternal side effects. There was no difference in neonatal outcome.

The Truview EVO2 blade facilitates the view of vocal cords by indirect laryngoscopy and does not require the proper alignment of the oral, pharyngeal and tracheal axes as with the Macintosh blade. ⋯ Truview laryngoscope performed comparably to Macintosh laryngoscope in patients with normal airway; however, the Truview laryngoscope may be a better option in difficult airway situations when the Macintosh blade fails to show the glottic opening.

Comparative study of intrathecal hyperbaric versus isobaric ropivacaine: A randomized control trial.
Hyperbaric ropivacaine produce more reliable sensory and motor block, with faster onset, better quality of muscles relaxation than isobaric ropivacaine. So, this study was designed to compare the efficacy of hyperbaric ropivacaine with isobaric ropivacaine in patients undergoing lower abdominal surgery. ⋯ Intrathecal hyperbaric ropivacaine provides more rapid, adequate, and good quality of sensory and motor block with rapid post-operative recovery as compare to isobaric ropivacaine.

Emergence agitation (EA) in children is increased after sevoflurane anesthesia. Propofol and dexmedetomidine have been used for prophylactic treatment with controversial results. The aim of the present study was to compare the effect of a single dose of propofol or dexmedetomidine prior to termination of sevoflurane-based anesthesia on the incidence and severity of EA in children. ⋯ Dexmedetomidine 0.3 ug/kg(1) was more effective than propofol 1 mg/kg in decreasing the incidence and severity of EA, when administered 5 min before the end of surgery in children undergoing adenotonsillectomy under sevoflurane anesthesia.

To compare two different doses of propofol for laryngeal mask airway (LMA) insertion in children undergoing out-patient surgeries. ⋯ It seems that propofol doses of 2.5 and 3.5 mg/kg are equally effective for LMA insertion following intravenous midazolam, fentanyl, and lidocaine.
