INTRAVENOUS REGIONAL ANESTHESIA j . EVALUATION OF THREE DIPFERENT ADDITIVES TO LIDOCAINE

Abstract

Intravenous regional anesthesia (IVRA) is an effective way to provide anesthesia for hand surgery expected to last less than lh, but it dose not provide effective postoperative analgesia. In an attempt to improve perioperative analgesia, various analgesics have been administered concomitantly with the local anesthetic in IVRA with contradictory results. The present work was carried out to evaluate and compare three different additives (meperidine, ketorolac or clonidine) to lidocaine for intravenous regional anesthesia.

Our study comprised 80 adult patients (20-50 years). of both

sex and ASA physical status I or II who were scheduled for elective • hand or forearm surgery. They were randomly assigned to one of four equal groups 20 patients each:

Group I:

Each patient received 40 rnl normal saline solution con4Jining

200mg lidocaine (0.5% cone).

Group II:

Each patient received 40 rnL normal saline solution containing

200mg lidocaine (0.5% conc)with added 1 mg/Kg meperidine.

Group III:

Each patient received 40 rnL normal saline solution containing

200mg lidocaine (0.5% cone )with added 30. mg ketorolac.
