Who Seeks Abortions at or After 20 Weeks?

Forty years of published research (1966-2006) addressing physical intimate partner violence (IPV) and sexual health was reviewed (51 manuscripts) and synthesized to determine (a) those sexual health indicators for which sufficient evidence is available to suggest a causal association and (b) gaps in the literature for which additional careful research is needed to establish causality and explain mechanisms for these associations. Sexual health was defined as a continuum of indicators of gynecology and reproductive health. IPV was consistently associated with sexual risk taking, inconsistent condom use, or partner nonmonogamy (23 of 27 studies), having an unplanned pregnancy or induced abortion (13 of 16 studies), having a sexually transmitted infection (17 of 24 studies), and sexual dysfunction (17 of 18 studies). A conceptual model was presented to guide further needed research addressing direct and indirect mechanisms by which physical, sexual, and psychological IPV affects sexual health.

We studied the steps in the process of obtaining abortions and women's reported delays in order to help understand difficulties in accessing abortion services. In 2004, a structured survey was completed by 1209 abortion patients at 11 large providers, and in-depth interviews were conducted with 38 women at four sites. The median time from the last menstrual period to suspecting pregnancy was 33 days; the median time from suspecting pregnancy to confirming the pregnancy was 4 days; the median time from confirming the pregnancy to deciding to have an abortion was 0 day; the median time from deciding to have an abortion to first attempting to obtain abortion services was 2 days; and the median time from first attempting to obtain abortion services to obtaining the abortion was 7 days. Minors took a week longer to suspect pregnancy than adults did. Fifty-eight percent of women reported that they would have liked to have had the abortion earlier. The most common reasons for delay were that it took a long time to make arrangements (59%), to decide (39%) and to find out about the pregnancy (36%). Poor women were about twice as likely to be delayed by difficulties in making arrangements. Financial limitations and lack of knowledge about pregnancy may make it more difficult for some women to obtain early abortion.

Proposed federal legislation would require physicians to inform women seeking abortions at 20 or more weeks after fertilization that the fetus feels pain and to offer anesthesia administered directly to the fetus. This article examines whether a fetus feels pain and if so, whether safe and effective techniques exist for providing direct fetal anesthesia or analgesia in the context of therapeutic procedures or abortion. Systematic search of PubMed for English-language articles focusing on human studies related to fetal pain, anesthesia, and analgesia. Included articles studied fetuses of less than 30 weeks' gestational age or specifically addressed fetal pain perception or nociception. Articles were reviewed for additional references. The search was performed without date limitations and was current as of June 6, 2005. Pain perception requires conscious recognition or awareness of a noxious stimulus. Neither withdrawal reflexes nor hormonal stress responses to invasive procedures prove the existence of fetal pain, because they can be elicited by nonpainful stimuli and occur without conscious cortical processing. Fetal awareness of noxious stimuli requires functional thalamocortical connections. Thalamocortical fibers begin appearing between 23 to 30 weeks' gestational age, while electroencephalography suggests the capacity for functional pain perception in preterm neonates probably does not exist before 29 or 30 weeks. For fetal surgery, women may receive general anesthesia and/or analgesics intended for placental transfer, and parenteral opioids may be administered to the fetus under direct or sonographic visualization. In these circumstances, administration of anesthesia and analgesia serves purposes unrelated to reduction of fetal pain, including inhibition of fetal movement, prevention of fetal hormonal stress responses, and induction of uterine atony. Evidence regarding the capacity for fetal pain is limited but indicates that fetal perception of pain is unlikely before the third trimester. Little or no evidence addresses the effectiveness of direct fetal anesthetic or analgesic techniques. Similarly, limited or no data exist on the safety of such techniques for pregnant women in the context of abortion. Anesthetic techniques currently used during fetal surgery are not directly applicable to abortion procedures.
