Magnesium is actually a non-competitive NMDA-antagonist and can potentiate opioid activity with central desensitisation (18).ThereareafewstudieswhichhavelookedattheanalgesiceffectsofIVmagnesiuminpatientsundergoingspinal anaesthesia;having said that,noneofthemhaveincludedanobstetric population(3-5).Inallofthesestudies,lowerdosesofMgSO4 (rangingfrom1.03gto12.35g)wereusedandtheinfusions had been began immediately after lumbar puncture.

Intrathecal and/or epidural magnesium has been shown to become helpful as an analgesic adjuvant in obstetric(healthful(15,16,20)andmildpre-eclamptic(17)sufferers)andnon-obstetricpopulations(1).Ofthefourobstetric research,one particular(16)usedcombinedspinalepiduralanaesthesia, whereasthreestudies(15,17,20)utilisedspinalanaesthesia with different intrathecal drug combinations, creating the comparisonofdatadifficult. We observed a more quickly onset of sensory block in Group Mg than in Group C. In mild pre-eclamptic sufferers, Malleeswaran etal.(17)addedmagnesiumtotheintrathecal10mgbupivacaine-25 fentanyl mixture and reported a slower onset of sensory and motor block following magnesium compared to the manage group. The time difference was roughly one minute andhadnoclinicalsignificance.Althoughnosignificantdifference was detected, in their study T4 level was achieved in 70 and 46.7 with the sufferers in the magnesium and control groups, respectively, andT6 level was reported as the maximumsensorylevelintherestofthepatients.Ghrabetal.(20)Balkan Med J, Vol. 31, No. two,observed no variations in onset occasions of sensory block in the T4 level amongst the groups with or without having intrathecal magnesium.Unlugencetal.(15)observedaprolongationin sensory block onset by a single minute in sufferers with intrathecal bupivacaine-magnesium combination in comparison with bupivacaine-fentanyl.Noneoftheseobstetricstudiesexplainedtheir findingsforsensoryblockonsetandlevel.Ozalevlietal.(21) studied the impact of intrathecal magnesium added to isobaric bupivacaine-fent.
