Delivery outside the hospital is an emergency situation with possible fatal complications. The health care providers in emergency medicine should be properly trained for the medical care of such patients. The recognition of signs of inevitable delivery is crucial before the decision to transport the labouring women to the hospital. In such circumstances we should be prepared for normal delivery, where physiological support is most important, to high risk delivery with the need for newborn or women’s resuscitation.
We present recommendations for delivery during the transport to the hospital.

The incidence of birth outside the hospital is low and varies in different societies. There are three main groups of pregnant women, delivering outside the hospital. The women who decided for the home birth (should be the low risk pregnancy), unintended delivery outside the hospital (no time for transport) and the unwanted pregnancies, usually in the low socioeconomic status population.
Intended home birth in well-
The United Kingdom Royal College of Obstetricians and Gynaecologists are supportive of home birth for low risk women. But the American Congress of Obstetricians and Gynaecologists warn that 'planned home birth is associated with a twofold to threefold increased risk of neonatal death when compared with planned hospital birth . So in home birth, when transport to the hospital is needed, previously low risk woman becomes a high-
In England national study there was a higher risk (OR 1,75) of complications (stillbirth after start of care in labour, early neonatal death, neonatal encephalopathy, meconium aspiration syndrome, brachial plexus injury, fractured humerus, or fractured clavicle) in home birth nulliparous women when compared to hospital setting. Home birthing nulliparas were transfered to the hospital in 45 %, and in multiparas transfer was needed in 13 % of cases .
Unintended delivery outside of the hospital is usually a quick event, with a good outcome. It usually happens when the labour is too quick.
In Slovenia there were 0,1 % of deliveries outside the hospital between 2008-
The third group of deliveries outside the hospital are in women with a low socioeconomic status, teen pregnancies, unwanted or hidden pregnancies. Those are high-
PHYSIOLOGY OF THE NORMAL DELIVERY
Labour is defined as the process by which the fetus, placenta and fetal membranes are expelled from the uterus. There are three stages of labour.
The first stage begins with regular painful contractions that result in dilatation of cervix, passage of blood-
The second stage starts with full dilatation of cervix and ends with the delivery of the baby. In this stage fetal head and body pass through the birth canal. Because of the asymmetry of the shape of both, the fetal head and the maternal bony pelvis, rotation is required for the fetus to successfully negotiate the birth canal. In average the second stage of labour lasts from 1 to 2 hours for nulliparous and 0.5 to 1 hour for multiparous women.
The third stage starts with the delivery of the baby and ends with the delivery of the placenta with fetal membranes. If experienced, we manage it actively to reduce postpartum haemorrhage otherwise physiological management is recommended .
Active management of the third stage means: the rutine use of uterotonic agents (oxytocin 5 I.E. i.v. after the delivery of first shoulder of the baby), clamping the cord and cutting and controlled cord traction after the signs of separation of the placenta.
Physiological management of the third stage means no routine use of uterotonic drugs, no clamping of the cord until pulsation has stopped and delivery of the placenta by maternal effort.
It is important to monitor and record the blood loss after the delivery.
TAKING THE DECISION: TRANSFER TO THE HOSPITAL
OR DELIVERY OUTSIDE THE HOSPITAL?
With signs of inevitable delivery (seeing baby in the vulva, pregnant women has unbarring feeling of pushing, full cervical dilatation) we should prepare for delivery outside the hospital (Figure 1).
When there are no signs of inevitable delivery we should collect and evaluate necessary clinical data and risk factors from obstetrical history and physical examination that includes assessment of vital signs of women and vaginal examination . We try to answer the following questions:
About the woman:
About the unborn baby:
Figure 1. Algorithm of decision for delivery or transport to the hospital.
The progress of labour is the most important information. We assess cervical dilatation and labour progress and consequently predict the duration of labour by vaginal examination. Be sure that the vaginal examination is really necessary and will add the necessary information to the decision making process. We should then estimate the time it takes to arrive to the hospital and then decide if we have enough time to transport .
If we expect any complications, the transport to the hospital is necessary. Circumstances that will require operating room, special equipment and educated staff are: twins, breech presentation, face presentation, transverse lie, placenta previa, abruptio placentae, and prolapse of the umbilical cord. Women with chronic diseases or uneventful history are considered high risk and should deliver in the hospital. We also try to transport preterm pregnant women as soon as possible.
Treat all women with respect and communicate with her. Give her proper psychological support. Her position during transport should be on her left side, to prevent the vena cava syndrome. Also we should find the position in which the woman feels as comfortable as possible before and during the transport. She should be dressed or wrapped in the blanket, so that she feels comfortable and decent. Communication and companionship is necessary, she should not feel afraid .
The head of the patient should be at the door of the ambulance car with the feet towards the driver, so you have enough space for the management of the delivery if necessary. Insert the intravenous path (G18) in the left forearm not to be disturbed during the transport. Heat the ambulance if you have to deliver (to prevent hypothermia of the newborn). Monitor the frequency and intensity of contractions (place your hand on the uterus) and monitor the fetal heart rate. Prepare the labour set and medicines for labour and resuscitation of the newborn. Stop the ambulance at a safe place if the delivery is imminent .
Prepare for neonatal resuscitation.
If the delivery is imminent, prepare and secure the place, check the air temperature and consider proper light. Communicate with the woman and try to offer some privacy. The medical personnel present should work as a team, so we divide roles -
When the fetal head is descending through birth channel, there is pressure on the rectum and woman feels the urge to push. She should take a deep breath, brace herself under her knees and push as if she would like to void.
As we see the fetal head in the vulva in the it is time to prepare for the perineum protection
and the delivery (Figure 2).
Figure 2. Fetal head seen in vulva.
The team leader washes his hands, opens sterile labour set, and puts sterile gloves on his hands. He puts a gauze over his right hand, covers the anus and protects the perineum with a gentle pressure. At the same time he maintains flexion of the head (Figure 3). The right hand stays on perineum throughout entire delivery. With the left hand he controls delivery of head it should be as slow that the perineum adjust and extends with a minimal trauma.
Figure 3. Right hand protecting perineum, left hand controlling the delivery of the head.
When the head is delivered, he wipes the baby’s face with his left hand and then he waits for external rotation of the head (internal rotation of shoulders) -
Figure 4. Delivering the anterior shoulder with gentle downward traction.
Posterior shoulder is delivered by upward traction. We must not pull, but these movements should be performed with the minimal force possible. When the anterior shoulder is delivered, it is time to administer 5 I.U. of oxytocin intravenous in bolus to accelerate delivery of placenta. The body of the baby is slippery, it should be put on the mother’s abdomen . After delivery the baby should be wiped dry and kept warm. Drying and wiping the baby usually produces enough stimulation to induce effective breathing. Team leader clamp the cord with two clamps (peans) 15 cm away from the umbilicus and cuts the cord with scissors between the clamps. It is recommended to delay cord clamping for at least one minute (or after it stops pulsating). One of the team members takes over the care of the newborn. It's important to keep the baby warm. It is recommended to avoid hypothermia and maintain the baby’s temperature between 36.5-
The team leader waits for the classic signs of placental separation: mild contractions of the uterus, lengthening of umbilical cord, gush of blood from vagina, uterine fundus becoming flatter. When the placenta is fully separated from the uterine wall, we can gently remove it by downward traction of the umbilical cord with one hand while with other hand we gently massage the uterine fundus to stimulate the contraction and minimise bleeding. Removed placenta is examined for the missing parts.
We have to transport the mother, the newborn baby and the placenta (with fetal membranes) to the hospital. During the transport we assess the infant and mother’s vital signs, tonus of uterus and mother’s vaginal bleeding. We transport the mother and the baby secured, the mother lying on her back and the baby in the car seat for the newborn. Keep them as close as possible.
It is normal to lose some blood at delivery (usually around 300 to 500 ml). The normal pregnant women can tolerate up to 1000 ml of blood loss.
Risk factors for excessive blood loss are: previous postpartum haemorrhage, low maternal haemoglobin (below 85 g/L), BMI more than 35 kg/m2, parity 4 or more, haemorrhage before delivery, overdistended uterus (large for gestational baby, multiple pregnancy, polyhydramnios), uterine abnormalities, low-
In the case of risk factors, be prepared! After the delivery the bladder should be empty, we should regularly massage the uterus and give uterotonic drugs (oxytocin 5-
WHAT TO WRITE DOWN
In Slovenia a dedicated labour form is used to record the data. Besides the woman’s personal data (the name, surname, date of birth), the health history and antenatal history are recorded. Any allergies are noted also the medicines she is taking.
From the labour itself it’s important to record:
In the first minutes after delivery, we should evaluate the condition of the baby: respiration, heart rate, tone and colour. Usually we grade all these as the Apgar score.
The baby should be as close to his mother as possible, if possible put the baby skin to skin on woman’s chest and wrap them both together. Assure the right temperature for the baby.
If the basic resuscitation is needed, start with air. Resuscitate according to the guidelines for neonatal resuscitation.
In the presence of meconium, do no suction or intubation before the baby’s shoulder are born or if baby is breathing normally and crying .
The safest way to deliver is in the hospital. Majority of newborns are born there. Some deliveries are too quick, or in some way unexpected and those need the transport to the hospital accompanied with emergency medical staff. In the last years there is a trend for home delivery with a trained midwife support for low risk pregnancy, which can be complicated with the need for emergency transport.
Emergency medical professionals should be properly and regularly trained for neonatal and pregnant women resuscitation and delivery assistance. The signs of imminent delivery and the need of urgent transfer in high risk cases should be recognised.
