dorsal n of penis (Sensory and SAN)
cavernouse nn (PAN from prostatic plexus)
43
Q

What is the action of nn on penis and glands of perineum

A

erection (PAN tone to vasodilate by cavernouse nn) contraction of bulbospongiosus and ischiocavernosus mm. (prevents venous drainage)

44

can be continuously delivered via an indwelling catheter
does not have pain from uterine contraction or passage of infant through canal

66

anesthetic delivery into epidural space of sacral anal, anesthesia to S2-S4
numb pain from cervix, vagina, perineum
Uterine contractions still felt
still can walk
cannot feel passage through birth canal
67
Q

What is a pudendal nerve block

A

provides anesthesia of majority of perineum and inferior 1/4 vagina
pain from uterine contractions, passage through birth control is felt
minimize pain from potential treating or episiotomy

68
Q

Where is a pudendal n localized

A

palpate ischial spin and sacrospinous ligament

69
