Meaning of Slow progress in labor?

"The labour has two stages. The first and second stages are from the onset of regular uterine contractions to full dilation of the cervix, and the second stage is from Full dilation of the cervix to the expulsion of the baby. Usually, in the first pregnancy, the first stage lasts not more than 24 hours. The second stage lasts not more than 2 hours without anaesthesia and not more than 3 hours with anaesthesia in a second pregnancy, so the first stage of labour does not last more than 10 to 14 hours, and the second stage of labour does not last more than 1 hour without anaesthesia and two hours with anaesthesia. So prolonged labour is when this period of the above has crossed, and still, the patient has not delivered. So, the causes of protracted labour could be a big baby and inefficient uterine contractions. The incidence of prolonged labour is around 8 to 10%. The leading causes are inefficient uterine contractions, big babies, and maternal obesity. The mental effects of protracted labour are that she can have postpartum haemorrhage. She can have maternal exhaustion, urinary retention, and so on. What are the fetal effects? Fetal effects could be due to prolonged labour. There could be fetal distress there could be birth asphyxia, and there could be shoulder dystocia. So how do we treat it? We need to correct the cause. The cause is most commonly inefficient uterine contractions. We give oxytocin inc, release the uterine contractions, and try to deliver the baby. If any of the measures fail, the last resort is to take up the patient for a C-section"
