Q

What are two non-pharmacological types of pain relief commonly used in labour ?

A
  1. TENS

2. Water birth

17
Q

What is TENS?

A

TENS is a drug-free kind of pain relief often used by women in the early stages of labour. TENS stands for Transcutaneous Electrical Nerve Stimulation.

A maternity TENS machine consists of a battery-powered, hand-held controller connected by fine leads to four flat pads. The pads are covered in a firm gel that helps them stick to your back.

The machine sends small, safe pulses of electrical current via the leads to the pads on your skin. The pulses pass through your skin and into your muscles and tissues. This gives you a gentle tingling or buzzing sensation, which may be stronger or weaker, depending on the setting level.

18
Q

What are pharmacological types of pain relief used in labour?

A
  • Oral
  • Inhalation
  • Injectable
19
Q

What are regional types of pain relief used in labour?

A
  • Spinal (most common)
  • Epidural
  • Combined
20
Q

What is an epidural?

A

An injection in your back to provide pain relief

21
Q

What is a spinal? How does it differ from an epidural?

A

Spinal uses a much smaller needle, directly into the cerebrospinal fluid that surrounds the spinal cord.

A spinal block is a single injection of local anaesthetic medications and so there is only one opportunity to deliver the medications. With an epidural, a catheter sits in an epidural space so drugs can be delivered as needed to extend the duration of the block.

22
Q

When would general anaesthetic be used in labour?

A
  • In an emergency
  • If there’s a reason why a regional anaesthetic isn’t right for you, such as a blood clotting condition, infection or a back issue.
23
Q

Why shouldn’t ibuprofen be used during pregnancy (after 30 weeks)?

A

Ibuprofen causes premature closure of the foetal ductus arteriosus –> can lead to a heart problem in your baby and a reduced amount of amniotic fluid.

24
Q

What inhalational pharmacological agents are used for pain relief in labour?

A

Nitrous oxide:

  • Entonox (50% NO, 50% O2): gas and air
25
Q

What are side effects of inhalational agents?

A

Side effects include dizziness, nausea and amnesia

26
Q

What opioids are used for severe pain in labour? What are side effects?

A

Diamorphine (NHS Heroin)

  • Sedation
  • Nausea and vomiting
  • Respiratory depression

Pethidine (injection)
- Warning in epilepsy

27
Q

What local techniques can be used to relieve pain during labour?

A

Pudendal block
