BACKGROUND: Pai. management followi.g caesarean secti.n sti.l remai.s a challenge i. our envi.onment. Most potent analgesi.s are ei.her not readi.y avai.able or expensi.e. Di.lofenac supposi.ory i. an NSAi. that can be used for postoperati.e analgesi.. i. i. avai.able and affordable. OBJECTi.E: To compare the effi.acy and safety of combi.ed rectal di.lofenac and i.tramuscular pentazoci.e wi.h i.tramuscular pentazoci.e alone for post operati.e pai. control followi.g lower segment caesarean secti.n. METHODOLOGY: A total of 120 women who met the selecti.n cri.eri. scheduled for caesarean secti.n under spi.al anaesthesi. wi.h bupi.acai.e were randomi.ed i.to two equal groups to recei.e ei.her 75 mg di.lofenac supposi.ory 12 hourly for 24 hours or one anusol supposi.ory (the placebo) 12 hourly for 24 hours. Both groups recei.ed pentazoci.e as pri.ary analgesi.. RESULT: The pri.ary outcome measure i. the proporti.n of pati.nts wi.h severe pai. at 24 hours usi.g the vi.ual analogue rati.g scale. Secondary outcome measures are the ti.e from surgery to ambulati.n, Passage of flatus, maternal sati.facti.n and presence of compli.ati.ns. Stati.ti.al analysi. was done usi.g spss versi.n 22 and graph pad stati.ti.al package. Student T-test was used for conti.uous vari.bles whereas chi.square was used for categori.al vari.bles P CONCLUSi.N: Adjuvant rectal di.lofenac i. superi.r to pentazoci.e alone i. the management of pai. after caesarean secti.n. Less number of pati.nts had moderate to severe pai. at 24 hours post operati.n. Maternal sati.facti.n i. relati.n to pai. management i. better wi.h di.lofenac supposi.ory. The levels of compli.ati.ns were comparable i. both groups.
