RT Journal Article SR Electronic T1 BET 2: Does magnesium prolong the analgaesic effect of bupivacaine in a fascia iliaca nerve block? JF Emergency Medicine Journal JO Emerg Med J FD BMJ Publishing Group Ltd and the British Association for Accident & Emergency Medicine SP 415 OP 416 DO 10.1136/emermed-2015-204758.2 VO 32 IS 5 A1 Peter Kilgour A1 Babajide Oni A1 Hisham Ghanayem A1 Dianne Tabone YR 2015 UL http://emj.bmj.com/content/32/5/415.abstract AB A shortcut review was carried out to establish whether routine use of magnesium as an adjunct to bupivacaine fascia iliaca nerve block in femoral neck fracture was effective in prolonging its analgaesic effect. Forty-four papers were found using the reported searches, of which one presented the best evidence to answer the clinical question. The author, date and country of publication, patient group studied, study type, relevant outcomes, results and study weaknesses of this paper are tabulated. It is concluded that while magnesium has the potential to prolong the analgaesic effect of bupivacaine further studies are needed to clarify its exact role and safety profile.
