Enrollment: 45
Healthy volunteers: yes

Brief summary:
45 pregnant women undergoing cesarean section were enrolled in the study in november 2006 to march 2007. 2 ml of 0.5% levobupivacaine was added to 1 ml of saline in group I, 1 ml of 15 µcg of fentanyl in group II and 1 ml of 1,5 µcg sufentanil in group III by intratechal administration. Hemodynamic parameters, characteristics of sensory and motor blockade, peri-operative and postoperative visual analogue scale (VAS) pain scores, the time to the first analgesic requirement and adverse effects were recorded.

Detailed description:
45 pregnant women undergoing cesarean section were enrolled in the study in november 2006 to march 2007. Using CSE technique, 2 ml of 0.5% levobupivacaine was added to 1 ml of saline in group I, 1 ml of 15 µcg of fentanyl in group II and 1 ml of 1,5 µcg sufentanil in group III by intratechal administration. Hemodynamic parameters, characteristics of sensory and motor blockade, peri-operative and postoperative visual analogue scale (VAS) pain scores, the time to the first analgesic requirement and adverse effects were recorded.

Arms:
arm 1: Levobupivacaine, a local anesthetic agent, is indicated for the production of local or regional anesthesia or analgesia for surgery, for oral surgery procedures, for diagnostic and therapeutic procedures, and for obstetrical procedures.

Injection Surgical anaesthesia

Adult: Epidural block: 50-100 mg (10-20 ml) of a 0.5% solution or 75-150 mg (10-20 ml) of a 0.75% solution. Caesarean section: 75-150 mg (15-30 ml) of a 0.5% solution. Spinal block: 15 mg (3 ml) of a 0.5% solution. Max: 150 mg/dose; 400 mg/day. Injection Peripheral nerve block

It works in the brain and nervous system to cause anesthesia and decrease pain.

Indications:

Adult: PO Breakthrough cancer pain As a loz: Initially, 200 mcg over 15 minutes for an episode of breakthrough pain; may repeat once after 15 minutes if needed. Not more than 4 unit doses/day. IV Adjunct to general anesth Patients w/ spontaneous resp: Initial: 50-200 mcg, w/ supplements of 50 mcg. Patients w/ assisted ventilation: Initial: 300-3,500 mcg (up to 50 mcg/kg), w/ supplements of 100-200 mcg depending on response.

Maintenance: Additional doses of 0.5-10 mcg/kg may be given if needed. Max (total dose): 30 mcg/kg. Post-op pain Initial: 30-60 mcg. Additional doses of up to 25 mcg may be given at intervals of ≥1 hr if needed. Epidural Pain relief during labour and delivery W/ bupivacaine: 10-15 mcg w/ or w/o epinephrine. May repeat dose twice at intervals of ≥1 hr till delivery. Max (total dose): 30 mcg.
