Youshould redo the test after you’ve worked through 10-1 What is analgesia?the unit, to evaluate what you have learned. Analgesia means the relief of pain. Drugs used to relieve pain are called analgesics. Objectives Analgesics must not be confused with sedatives which do not relieve pain but only make the patient drowsy. When you have completed this unit you should be able to: 10-2 What is anaesthesia? • Explain the differences between Anaesthesia means the loss of all sensation, analgesia, anaesthesia and sedation. including pain.

Contractions are most painful when the cervix is fully dilated and the patient has an urge to bear down. At first the pain is felt over the abdomen but later, when the cervix is nearly fully dilated, pain is felt in the lower back.
