INTRACUTANEOUS STERILE WATER INJECTIONS IN THE RHOMBUS OF MICHAELIS AFTER LOCAL ANAESTHESIA: A COMPLEMENTARY THERAPY FOR RELIEVING PAIN DURING CHILDBIRTH

Abstract

Introduction

Sterile water injections in the Rhombus of Michaelis are used as a simple technique to alleviate back pain during childbirth. However, the technique itself is painful and requires two professionals to carry it out.

Objective

To assess the level of pain associated with the technique of sterile water injection after the injection of lidocaine, compared to the technique of sterile water injection without lidocaine. The aim was also to assess whether both techniques (with and without lidocaine) reduce back pain during childbirth.

Material and Methods

A semi-experimental study was carried out. The level of pain was assessed using the VAS scale before the technique, during the technique, and 30 minutes after the technique in two groups of expectant mothers (with and without lidocaine). The expectant mothers were divided randomly into two groups. The SPSS programme was used for the data analysis.

Results

The results showed that the technique with lidocaine could be undertaken by one professional and was significantly less painful than the technique without the anesthetic. In both cases, the level of pain stated prior to the sterile water injection was reduced 30 minutes after the injection. The reduction in pain was clinically relevant.

Conclusions

Sterile water injection in the Rhombus of Michaelis is an effective technique for reducing back pain during childbirth. The injection of lidocaine prior to the technique enables its use without the main disadvantage: pain on injection of sterile water.
