Background: In an effort to effectively reduce placental site haemorrhage in a number of cases alternative methods were sought and myometrial transfer of oxytocin by insulin syringe is the result.
Aim: This is a comparative study of 4 IU oxytocin by stab intra-myometrial injection (SIMI) and conventional 10 IU parenteral during LSCS with the objective of comparing the blood loss.
Materials & Methods: A prospective study of Group A 100 patients subjected to SIMI by insulin syringe and Group B 100 patients administered 10 IU of oxytocin IV after baby birth. The blood loss and adverse effects of oxytocin during LSCS compared between the 2 groups.
Results: It’s observed that in all the emergency & elective cases of Gr. A the mean blood loss is less by 40.1 ml (482.8 ml) as compared to 522.9 ml in Gr. B cases.
Discussion: The placental site haemorrhage plays the dominant role during caesarean sections to decide the maternal mortality and morbidity. Intra-myometrial uterotonics have the effect of faster action reducing the 3rd stage time and bleeding thereby the total blood loss by 40.1 ml. in this study.
Conclusion: SIMI of low dose oxytocin may be an alternate step for 3rd stage management and more studies may be needed in this regard.
