Introduction: Labour pain is among the most severe pain a woman can experience in her lifetime. Painful labour has decrimental effects on both
mother and fetus leads to severe physical and psychological stress. Maternal hyperventilation in response to pain reduces fetal oxygenation and
hypoventilation between contractions combined with decreased blood ow worsens fetal hypoxemia. It has been suggested that conning women
to bed during labour may cause the labour to be longer and more painful with increase in abnormal presentation, instrumental deliveries and fetal
distress.
Aims And Objectives:The onset, quality and duration of their analgesic action. Incidence of unwanted effects like muscle weakness, hypotension,
pruritus, nausea/vomiting, fetal bradycardia by the individual drugs.
Materials And Methods: The study was conducted in the department of anesthesia, Darbhanga Medical College & Hospital, Laheriasarai, Bihar.
Methods of collection of data (including sampling procedure if any) : After institutional committee approval and written informed consent from
parturients and their relatives for the procedure the study was conducted and data were collected.
Results: Duration of analgesia was found varying widely. It was 55±12.34 minutes in Group I whereas 75 ±14.36 minutes in Group II. The
incidence of pruritus almost mild or negligible in both groups. The incidence of motor weakness in group II was 24 (80%) whereas in group I it was
10(33%). There was signicant statistics difference in motor weakness between two groups (p< 0.001) by Chi square test 9 with yate's correction.
Other side effects differences between two groups were not statistically signicant.
Summary And Conclusion:Both the drugs provided excellent quality of analgesia to the parturient in pain. The difference in duration of
analgesia was signicant between the two groups statistically. Mean duration of analgesia lasted for 55 minutes in group I whereas in group II, it
lasted for 75 minutes. Main side effects encountered in this study were motor weakness of longer duration in group II than in group I. Other side
effects like nausea-vomiting were comparable to each other and were minimal in nature.
