  • Information Leaflet for Women Undergoing Caesarean Section
    Maternity Services Information Leaflet for Women Undergoing Caesarean Section Cavan & Monaghan Hospital Tel. 049 4376613 Information Leaflet for Women Undergoing Caesarean Section Introduction A vaginal delivery is the most common way to give birth. However, a caesarean section may be advised in certain circumstances. A caesarean section is when the baby is “delivered” through an incision (cut) in the abdomen (tummy). Caesarean section rates in Ireland are about 20% to 25%. Caesarean section may be planned in advance (elective caesarean section) or be performed at short notice, particularly if there are complications in labour (emergency caesarean section). Some reasons for caesarean section include: • you have placenta praevia (when the placenta is low-lying in the womb and covering part of the womb entrance). • your baby is in the breech (botto) position. • your labour fails to progress naturally. • caesarean section is usually performed when a vaginal (normal) birth could put you or your unborn baby at risk. The Procedure 1. Your caesarean section is usually performed under a regional anaesthesic, which numbs the lower part of your body but means you will be awake during your operation. This is safer for you and your baby than a general anaesthetic, when you are put to sleep. However sometimes it is necessary to give you an anaesthetic. 2. The regional anaesthesia will be given into your spine (called an epidural). 3 3. You will need to have a catheter (tube) inserted into your bladder to empty it, because with a regional anaesthetic, you may not be able to tell if your bladder is full and needs emptying.

  • Increasing Caesarean Section Delivery: a Threat to Urban Women’S Health?
    Title: Increasing caesarean section delivery: A threat to urban women’s health? Authors: Sancheeta Ghosh* and K.S James† Introduction: A consistent increase has been observed in the rate of caesarean section deliveries in most of the developed countries and in many developing countries including India over the last few decades derivate a matter of concern among the social scientists. In recent years, especially in parts of world, it is often argued that with thriving private practice, obstetricians increasingly prefer for medicalised birth than normal birth. In addition, there is also some evidence from Western countries on increasing preference from women who want to deliver their child through the c-section. The rates of caesarean section in many countries have increased beyond the recommended level of 5-15 % by WHO, almost doubling in the last decade. In high income countries like Australia, US, Germany, Italy and France, the rates have gone phenomenally (Sufang et.al, 2007). The present data shows that in United States, 1.2 million or 29.1 percent of life births were by c-section delivery in the year 2004 (NIHS, 2006). Of the 12 Latin American countries reviewed recently Brazil had the highest rate of c-section (Behague et al. 2002). Similar trends have also been documented in low income countries such as Brazil, China and India, especially for births in private hospitals (Potter et al. 2001; Cai et al. 1998; Mishra and Ramanathan, 2002). In a developing * Research Associate at International Centre for Research on Women, New Delhi. † Professor and Head, Population Research Centre.

  • After Your Caesarean Section
    After your caesarean section Information to help your recovery from your caesarean birth. What to expect in hospital In the recovery room After the operation you will transfer to the recovery room where you will be closely observed for about an hour before being moved to a room in the maternity ward. As soon as you feel able, we encourage you to cuddle your baby skin-to-skin, this helps regulate their temperature and breathing. Usually your baby will be ready to breastfeed within the first hour after birth; the staff will assist you. In the maternity ward The postnatal stay is usually 3–5 days after a caesarean, but you may go home or transfer to a facility closer to home sooner if you are well enough. When you first arrive in the ward you will have a drip in your arm, a catheter (tube) to empty your bladder and a pump with a button that you can give yourself pain relief as you need it. These will be removed as you recover over the next 12–24 hours. You may start to drink sips of water straight away, then slowly build up to eating normally. If you feel sick, stop and let your midwife know. Your baby will be in the cot next to your bed; you can bring baby into bed with you for feeding and cuddles, but make sure someone is with you at first as you must be careful not to fall asleep with baby in bed. Once you are more mobile usually after 8 hours you can continue to do more for your baby yourself.

ABSTRACT Background: FHR monitoring plays the most important role in management of labouring patient when incidence of fetal hypoxia and progressive asphyxia increases. Now a day’s cardiotocography (CTG) become a popular method for monitoring of fetal wellbeing and it is assisting the obstetrician in making the decision on the mode of delivery to improve perinatal outcome. The aim of the study was to assess the effect of cardiotocography on perinatal outcome and its correlation with caesarean section rate. Methods: In this prospective observational study 201 gravid women with high risk pregnancy in first stage of labour were taken. Result was assessed in the form of Apgar score at five minute, NICU admission, perinatal mortality and mode of delivery. Statistical analysis is done by using Chi square test and p<0.05 is considered as statistically significant.
