Niðurstöður: Súrefnismettun sjónhimnuæða var marktækt hærri í slag-
æðlingum eftir innöndun á 100% súrefni hjá heilbrigðum einstaklingum
(p<0,0001) og glákusjúklingum (p=0,0011). Bláæðlingar mældust einnig
marktækt hærri í súrefnismettun eftir 100% súrefnisöndun heilbrigðra
einstaklinga (p<0,0001) og glákusjúklinga (p<0,0001). Meðalæðavídd
slagæðlinga minnkaði í heilbrigðum einstaklingum (p<0,0001) ásamt
glákusjúklingum (p=0,0011) við innöndun á 100% súrefni. Æðavídd
bláæðlinga minnkaði einnig við innöndun á 100% súrefni hjá báðum
hópunum (p<0,0001). Enginn munur var á milli hópanna í súrefnis-
mettun og æðavídd. Einnig var enginn munur á milli hópanna á svörun
við innöndun 100% súrefnis.
Ályktun: Innöndun á 100% súrefni eykur súrefnismettun í sjón-
himnuæðum ásamt því að minnka æðavídd samanborið við normal
aðstæður. Enginn munur var á svari hópanna við súrefnisinnöndun.
Súrefnismælirinn er næmur á breytingar í súrefnismettun og samsvarar
sér vel í mælingum.

Introduction: The evidence on the potential influence of sexual violence
on women’s subsequent obstetric outcomes is scarce. Our aim was to
investigate whether women exposed to sexual violence in adolescence
or adulthood present with different obstetric outcomes than women
with no record of such violence.
Methods and data: Data from the Rape Trauma Service at Landspitali
(RTS) were linked with data from the national Icelandic Birth Register
(IBR). Women who attended the RTS in 1993-2010 and subsequently
delivered through 2012 formed our exposed cohort (n=1069). Women
who had not attended the RTS were randomly selected from the IBR for
our unexposed cohort, matched on age, parity and season of delivery
(n=9127). Poisson regression was used to obtain Relative Risks (RR) with
95% confidence intervals (CI).
Results: Compared with unexposed mothers, exposed mothers presen-
ted with increased risks of maternal distress during labor and delivery
(RR 1.77, CI 1.07, 2.96), prolonged first stage of labor (RR 1.42, CI 1.04,
1.92) and operative vaginal or emergency cesarean delivery (RR 1.17, CI
1.01, 1.35). We found no difference regarding elective cesarean section.
Infants of exposed mothers were at an increased risk of being admitted
to the neonatal intensive care unit (RR 1.31, CI 1.02, 1.70). Overall,
somewhat stronger effects were seen for mothers assaulted ≤19 years
of age.
Conclusions: The findings from this population based cohort study
indicate increased risks of some adverse obstetric outcomes among
mothers exposed to sexual violence in adolescence or adulthood.

Introduction: We aimed to determine whether Swedish survivors from
the 2004 tsunami experienced increased risks of psychiatric disorders
and suicide attempts five years after repatriation.
Methods and data: Survivors repatriated from Southeast Asia (8762
adults and 3742 children) were matched with 864,088 unexposed adults
and 320,828 unexposed children on sex, age, and socioeconomic status.
Exposure severity was ascertained in a mail survey of 3534 survivors.
Psychiatric diagnoses and suicide attempts were retrieved from the
National Patient Register. Hazard ratios (HRs) and their 95% confidence
intervals (CIs) were adjusted for pre-tsunami psychiatric disorders, and,
for children, for parental pre-tsunami disorders.
Results: Exposed adults were more likely than unexposed adults to
receive any psychiatric diagnosis (6·2 vs. 5·5%; HRadj=1·21, 95%CI:
1·11-1·32), particularly stress-related disorders (2·1 vs. 1·0%; HRadj=2·27,
95%CI: 1·96-2·62) and suicide attempts (0·43 vs. 0·32%; HRadj=1·54,
95%CI: 1·11-2·13). Risk of stress-related disorders was pronounced
among survivors with severe exposure and during the first year post-
tsunami. There was no difference in overall risk of psychiatric diagnoses
between exposed and unexposed children (6·6vs. 6·9%; HRadj=0·98,
95%CI:0·86-1·11), although exposed children had higher risk for suicide
attempts with uncertain intent (HRadj=1·43; 95%CI: 1·01-2·02) and stress-
related disorders (HRadj=1·79; 95%CI: 1·30-2·46), primarily during the
first three months post-tsunami.
Conclusions: Disasters can, independently of previous psychiatric
morbidity, increase risk of severe psychopathology, mainly stress-rela-
ted disorders and suicide attempts, in children and adults.
E 59 Reaching out to women who are victims of intimate partner
violence

Introduction: Intimate partner violence (IPV) has been reported to have
a harmful impact on women’s health and welfare. Women who are
victims of IPV have been found to develop symptoms of post-traumatic
stress disorders (PTSD) and mental illnesses. Nevertheless, little is
known about disclosure of abuse to health care professionals. The
purpose of this study was to evaluate if disclosure of abuse in a clinical
and in a community setting, varied base on the type of data collection
method used, as well as to explore women´s development of symptoms
of PTSD and the outcome on their physical and mental health status.
Methods and data: Cross sectional research design was used. Data
were collected at one time in 2009 over a period of 9 months from 306
women ranging in age from 18-67 years. Out of those women, 55 (18%)
experienced abuse in their current marital/partner relationship and 17
women (31%) reported symptoms of PTSD.
Results: No difference was found on the proporton of disclosure of
