Topic Description

CHAPTER ONE

INTRODUCTION

Background to the Study

Maternal and perinatal health have emerged as the most important issue that determines global and national wellbeing because every individual, family and community is at some point intimately involved in pregnancy and the success of child birth (World Health Organization, 2005). Pregnancy and child birth is still considered a perilous journey despite the honor bestowed on womanhood and the appreciation of the birth of a new born baby.

 

According to World Health Organization (WHO) report, recent estimates revealed that over 350,000 women worldwide die from complications of pregnancy and childbirth- a reduction from the previous estimates of 536,000 per year (Hogan, Foreman & Naghavi, 2010; WHO, 2010; Khan, Wojdyla & Say, 2006). Out of this figure, 99% occur in the developing countries and 1% in the industrialized ones. The maternal mortality rate is highest in Sub-Saharan African countries, as the risk of dying from pregnancy-related cause is 1:16 in Africa but only 1:4000 in some developed countries (Lucas & Gilles, 2003). However for the first time in 2010, data showed that there is significant progress made in reducing maternal death globally (Gahr, 2011).

In Nigeria, the Maternal Mortality rate is still high as 59,000 women still die every year during pregnancy and childbirth (Centre for Reproductive Rights, 2012). These deaths are largely preventable. Equally of concern is that yearly, about 1,080,000 – 1,620,000 Nigerian women and girls suffer disabilities caused by complications during pregnancy and childbirth (Utoo, Musa Karshima & Ifenne, 2012). For every one that dies, 20- 30 more women suffer long term and short term disabilities such as chronic anaemia, maternal exhaustion or physical weakness, vesico-vaginal or recto-vaginal fistulae, stress incontinence, episiotomy wound breakdown, perineal trauma, chronic pelvic pain, Pelvic Infammatory Disease (PID), Infertility, ectopic pregnancy, emotional depression (Adedokun,2013).

Perineal trauma is one of the morbidities that results from childbirth. It is defined as any damage that occurs to the genitalia during childbirth spontaneously or intentionally by surgical invasion termed episiotomy (Kettle &Tohill, 2011). Women frequently incur perineal trauma at delivery (Fahami, Shokoni & Kianpour, 2012). About 70% of women giving birth vaginally sustain some degree of perineal trauma and it is associated with postnatal morbidity (Kettle, 2011; Smith, Price, Simonite &Burns, 2013). Several studies have reported the incidence of perineal trauma in the developed countries among women and the increased morbidity associated with it (Kettle & Tohill, 2011; Marsh, Lynne, Christine & Alison, 2011; Roos, Thakar & Sultan, 2010).

Perineal trauma could be in the form of first to fourth degree tears or an unnatural straight-edge cut from an episiotomy (Chapman, 2006). Episiotomy is a common surgical procedure experienced by women (Marsh et al, 2011). It is frequently done among pregnant women in labour and its practice dates back to the 16th century (Lang, Wong & Pun, 2006). Studies have revealed that episiotomy accounts for a large proportion of perineal trauma and there is no evidence that it prevents severe lacerations (Kumar, Ooi & Nicoll, 2012; Kettle & Tohill 2011; Fahami et al. 2012).

 

Few studies carried out in Nigeria on episiotomy and perineal trauma also revealed high incidences of episiotomy rate and perineal trauma among women (Chigbu, Onwere, Alika&Adibe, 2008; Enyindah, Tiebai, Anya &Okpanu, 2007). Enyindah et al, (2007) in the study carried out in University of Port Harcourt Teaching Hospital revealed that perineal trauma is one of the most common occurrences in vaginal deliveries with 40% of primigravida and 20% of multiparous women affected. Chigbu, et al (2007) assert that episiotomy rate in Abia State University Teaching Hospital, which constitute 45% of 100 vaginal deliveries is associated with major perineal lacerations.

Possible deleterious effects of perineal trauma are dyspareunia (painful intercourse) urinary and faecal incontinence as well as perineal pain (Kalichman, 2008). Some women report continued perineal pain 8 weeks after birth (22%) and others for up to a year or longer. The likelihood of perineal pain and sexual problem in the post partum period is the least for women with intact perineum,while women with episiotomy tend to report more pain with intercourse 3 months after delivery (Klein et al, 1994 in Kalichman, 2008; Marsh et al, 2011).Studies have shown that perineal massage can reduce the likelihood of perineal trauma and ongoing perineal pain and is well accepted by women (Aasheim, Nilsen, Lukasse & Reinar, 2011; Beckmann & Stock, 2013).

 

Perineal massage is a procedure which involves the gentle stretching of the tissues surrounding the vagina and the perineum. It is thought to improve perineal outcomes by stretching out the vaginal tissues, promoting perineal relaxation and improving circulation to the tissues. It is advocated during pregnancy to increase elasticity of the perineal muscles and reduce the risk of perineal trauma from episiotomy and spontaneous tear (Begley, 2014).

There are two forms of massage commonly practiced to reduce perineal trauma. The antenatal perineal massage which involves the massage of the perineal body and lower portion of the vagina in the last month of pregnancy by the woman or her spouse and the intra-partum massage, which is performed by the midwife in the second stage of labour. The antenatal perineal massage is the type that is being proposed in this study.

Evidences about perineal trauma and its impact on women’s health require the use of specific techniques to reduce the rate and morbidities associated with it.  Perineal massage has been found to reduce the likelihood of perineal trauma and poor perineal outcomes (Aasheim, Nilsen, Lukasse & Reinar, 2011 ; Beckmann & Stock, 2013; & Avery & Burket, 2012). The prevention of perineal trauma through the use of perineal massage may improve perineal outcome and reduce complications in the postpartum period. This will go a long way in reducing the morbidity and mortality associated with perineal trauma among women. This study is geared towards investigating the effect of perineal massage in reducing perineal trauma in women.

 

Statement of Problem

Perineal trauma is one of the morbidities that result from childbirth. Studies have shown that most women having vaginal deliveries sustain some form of perineal injury (  Fahami, Shokoni & Kianpour, 2012 ; Kettle & Tohill, 2011). Enyindah et al, (2007) in their study at University of Port-Harcourt Teaching Hospital also showed that perineal trauma is one of the most common occurrences in vaginal deliveries with 40% of primigravidae and 20% of multiparous women affected.

 

In the Federal Medical Centre, Yenagoa where this study is being proposed, the researcher observed that between January 2009 and January 2012, a total of four thousand and fifty one (4051) babies were delivered through spontaneous vaginal birth. Out of this, a total of one thousand, three hundred and sixty-six (1366) cases of perineal trauma (episiotomy, 1st , 2nd  and 3rd degree tears) were recorded (Labor ward register of FMC, Yenagoa). The total number of women who had episiotomy was eight hundred and twenty-six (826), those with first and second degree tears were four hundred and fifty-nine (459), while eighty-one had third degree tears. Among the recorded cases eight hundred and eighty-nine (889) were primgravidae and the others were multiparas. The average perineal trauma rate (episiotomy and lacerations) between the stated periods was estimated at 40.98% which is relatively high in comparison to the 10% recommended by the World Health Organization  (Alayande, Amole & Akin, 2012). In addition monthly statistics between January 2009 and January 2012, in mothers who attended Postnatal clinic at six weeks showed that more than 67.1% of women had wound breakdown during assessment. (Postnatal clinic records FMC, Yenagoa).

 

Since perineal massage has been implicated from studies as resulting in reduction of episiotomy rate, increase intact perineum and better perineal outcome, the present study investigated the effect of antenatal perineal massage on perineal trauma among primigravidae delivering in FMC, Yenagoa.

 

 

Purpose of the Study

The purpose of this study was to investigate the effect of antenatal perineal massage on reduction of the occurrence of perineal trauma among primigravidae in Federal Medical Centre Yenagoa, Bayelsa State.

Research Questions

  1. What is the incidence of perineal trauma among primigravidaewho participated in the study at Federal Medical Centre, Yenagoa?
  2. What is the difference in perineal outcome between primigravidae who perform perineal massage and primigravidae who did not?

 

  1. What is the relationship between maternal age and perineal of primigravidae who performed perineal massage.
  2. What is the relationship between fetal birthweight andperineal outcome of primigravidae who perform perineal massage
  3. To what extent is gestational age of the pregnancy of primigravidae who performed perineal massage andperineal outcome related?
  4. To what extent isbody mass index of primigravidae who performed perineal massage and perineal outcomerelated?

Hypotheses

  1. There is no significant difference in perineal outcome  between primigravidae who performed perineal massage and primigravidae who did not.
  2. There is no significant relationship inmaternal ages of primigravidae who performed perineal massage and perineal outcome.
  3. There is no significant relationship infetal birth weights of primigravidae who performed perineal massage andperineal outcome.
  4. There is no significant relationship in gestational age of pregnancies of primigravidae who performed perineal massage and perineal outcome.
  5. There is no significant relationship in body mass indexes of primigravidae who performed perineal massage and perineal outcome.

Significance of the Study

It will provide evidence-based knowledge to nurses, midwives and other healthcare professionals attending to women in labour on how to reduce the routine use of episiotomy and prevent various degrees of tears from occurring during labour.

The study will provide midwives and other health workers attending to mothers at birth, knowledge of the advantages of performing perineal massage and by explaining to them the various benefits, midwives will be providing women with options for optimal health that they may not have previously considered.

The study will add to the existing body of knowledge about perineal massage and provide women with information on how to prevent perineal tears from occurring during delivery.

It will also add to the body of knowledge about benefits derived from carrying out perineal massage and assist policymakers in the health sector to enforce and implement policies on the definitive use of episiotomy.

 Scope of the Study

The study covered all primigravidae in the 34th–36th  week of pregnancy with single gestation attending antenatal clinic in Federal Medical Centre, Yenagoa, who have not engaged inprior perineal massage. It also involved four times weekly perineal massage by the pregnant woman and/or her spouse in the last month of pregnancy.The studyinvolved primigravidae (experimental group) exposed to treatment (perineal massage), and primigravidae (control group) not exposed to treatment (no massage). It also involved determining the relationship between gestational age, body mass index, fetal birthweight and maternal age and the occurrence of perineal trauma.
