'For some reason I can't find this poem online at all; if you have a copy do you want to type it up or scan it, and then I can help you analyse it? If you're looking for some general analysis there's a decent discussion of some key themes (esp. the role of women) here though I'm not sure how relevant that is for this particular poem.
Here's the poem Lauren
All night in hospital I law
with my intemperate lover, pain.
A sister, calm in her serene
indifferent charity, sat to pray
for me, as for all suffering men,
beside my bed. Darkness and fear
rose up between me and her prayer
eclipsing the rich world of love
in which I grew, and richer trust
of lives that with my life were nourished.
And still my violator thrust
hard, hard, into a throbbing wound.
Fast in that grip I felt all cherished
images of good dissolve.
A cock crowed, and the sister rose,
yawning, to raise the window blind--
a row of cypress, scalpel-clean,
crowning a near-by hill, incised
the first of morning. Clear between
each cypress and its neighbour glowed
a winecup space of light defined
by the dark trees. Those winecups brimmed
with a new day's untasted wine:
I drank, until my spirit leapt
high on the morning's tranquil crest
and drunken sang its hope, and blessed
all suffering and rejoicing men.
I slipped from pain's embrace, and slept.
