Dexamethasone added to levobupivacaine in ultrasound-guided tranversus abdominis plain block increased the duration of postoperative analgesia after caesarean section: a randomized, double blind, controlled trial (original) (raw)

European review for medical and pharmacological sciences

Abstract

When added to local anaesthetics, dexamethasone can prolong the duration of peripheral blocks. Dexamethasone has a long and efficient glucocorticoid structure and presents anti-inflammatory properties. The aim of this study was to determine the effect of dexamethasone on the block duration added to levobupivacaine used for transversus abdominis block (TAP) applied to patients who underwent caesarean section. Forty-two patients with spinal anaesthesia in an American Society of Anesthesiologists (ASA) I-II risk group were included in the study and divided into two groups. Bilateral 30 ml 0.25% levobupivacaine and 2 ml 0.9% NaCl for the levobupivacaine group and bilateral 30 ml 0.25% levobupivacaine and 2 ml dexamethasone (8 mg) for the dexamethasone group were administered in a TAP block performed with ultrasonography. The time need for the first analgesic in the postoperative period was recorded. The numeric evaluation scale, and the total additional analgesic amounts were recorded. ...
