RESUMEN
Seventy five patients undergoing elective caesarean section under general anaesthesia were randomly divided into three groups of twenty rive patients each to receive placebo [group I], H-2 receptor blocker, ranitidine [group 11] and combination of H-2 receptor blocker and prokinetic drug, metoclopramide [group III]. Gastric fluid volume >25 ml was recorded in sixteen [64%] patients in-group I, in three [12%] patients in-group 11 and in six [24%] patients in-group HL Gastric fluid pH <2.5 was recorded in sixteen [64%] patients in group I, in one [4%] patient in group H and no patient in group HL Group H and HI patients were not statistically significantly different [p-value < 0.05] regarding both the parameters but group I patients were at a high risk [60%] of aspiration pneumonitis when compared to group 11 and HI [p-value > 0.05]
