Flashcards in Lecture 3 Deck (20):
1

Nerve types in pelvic structures

Sympathetic, parasympathetic, visceral afferent

2

Nerve types in perineum

Somatic motor and somatic sensory

3

Type of nerve fibres that allow pain sensation in pelvic organs

Visceral afferent

4

Visceral afferent nerve fibres of pelvic structures touching the peritoneum run alongside what?

Sympathetic fibres

5

Where do visceral afferent nerve fibres of pelvic structures touching the peritoneum enter the spinal cord?

Between T11 & L2

6

Where would pain be perceived in pelvic structures that touch the peritoneum?

Suprapubic

7

Visceral afferent nerve fibres of pelvic structures not touching the peritoneum run alongside what?

Parasympathetic fibres

8

Where do visceral afferent nerve fibres of pelvic structures not touching the peritoneum enter the spinal cord?

S2-S4

9

Where would pain be perceived in pelvic structures that dont touch the peritoneum?

S2-S4 dermatome (perineum area)

10

Pain sensation nerve fibre types below the levator ani

Somatic sensory

11

Nerve that allows pain sensation below the levator ani

Pudendal nerve

12

What pain does the pudendal nerve produce?

Localised pain within perineum

13

Sympathetic nerves of pelvis

Sacral sympathetic trunks, T11-L2, superior hypogastric plexus

14

Parasympathetic nerves of pelvis

Sacral outflow (S2,3,4), pelvic splanchnic nerves, mix with sympathetics in inferior hypogastric plexus

15

Where is the needle inserted for a spinal/epidural anaesthetic?

L3/L4 (vertebra above highest point of iliac crest is L4)

16

What structures do you pierce in a spinal anaesthetic that you do not in an epidural?

Dura mater, arachnoid mater, subarachnoid space

17

Signs that spinal anaesthetic is working

Flushed, warm lower limbs, reduced sweating

18

What fibres does the pudendal nerve have?

Somatic motor and somatic sensory

19

What procedures require a pudendal nerve block?

Episiotomy incision, forceps use, perineal stitiching

20

What can be used as a landmark for pudendal nerve block?

Ischial spines
