Abstract

In order to evaluate the effect of cesarean section on reduction of perinatal mortality rate (PMR). All cases delivered in Beijing Obstetrics and Gynecology Hospital from Jan. 1, 1980 to Dec. 31, 1992 were analysed. The total number of delivery in study period was 74,199. Number of cesarean section delivery was 18,557. The cesarean section rate was 25.0%. The total number of perinatal baby was 74,914. The number of perinatal death was 1,140. PMR was 15.2%. The 13 years were divided into three periods to compare the cesarean section rate and PMR. The 1st period was from 1980 to 1984. The 2nd period was from 1985 to 1988. Years from 1989 to 1992 were 3rd period. The cesarean section rate was increasing year by year. It was significant since 1985. On the other hand, the PMR was marked decreasing since 1983. But there was no continually decrease in 2nd period. In 3rd period trend of decreasing PMR was shown. There was no significant difference in PMR especially in neonatal mortality rate (NMR) between cesarean section group and vaginal delivery group in 1st period. In 2nd period the PMR and NMR of cesarean section group was higher than that of vaginal delivery group (P < 0.01). In 3rd period it was lower in cesarean section group (P < 0.05). Main causes of neonatal deaths in cesarean section group were congenital abnormalities and respiratory diseases. In 2nd period pulmonary hemorrhage, hyaline membrane disease were marked higher in cesarean section group. It was related to more premature and low birth weight babies in this group.(ABSTRACT TRUNCATED AT 250 WORDS)

Cesarean delivery on maternal request: obstetrician-gynecologists' knowledge, perception, and practice patterns.

OBJECTIVE: To examine obstetrician-gynecologists' knowledge, opinions, and practice patterns related to cesarean delivery on maternal request. METHODS: Questionnaires were mailed to 1,031 American College of Obstetricians and Gynecologists Fellows in February 2006, with a response rate of 68%. The questionnaire queried respondents' demographic characteristics, practices and attitudes surrounding vaginal and cesarean deliveries, knowledge and beliefs regarding the risks and benefits of elective and nonelective cesarean delivery, and counseling practices and department policies for cesarean delivery on maternal request. RESULTS: About half of respondents believe women have the right to cesarean delivery on maternal request, and a similar percentage acknowledge having performed at least one cesarean delivery on maternal request. Fifty-eight percent of respondents note an increase in patient inquiries regarding cesarean delivery over the past year, yet most of their practices do not have a policy regarding this procedure. Respondents attribute the increase in inquiries to the increase of information from the media and to convenience. Respondents cited more risks than benefits of cesarean delivery on maternal request, and nearly all discuss these risks with patients who are considering one. Females were more negative toward cesarean delivery on maternal request than males and endorsed more risks and fewer benefits. There were no relationships between assessment of risks and benefits or practice with clinician age or patient characteristics. CONCLUSION: Most obstetrician-gynecologists in this study recognized an increased demand for cesarean delivery on maternal request within their practices, while believing that the risks of this procedure outweigh the benefits. Clinicians would benefit from strong evidence regarding risks and benefits, evidence that is crucial to guiding policy making with regard to cesarean delivery on maternal request. LEVEL OF EVIDENCE: III.

The policy environment encouraging C-section in Lebanon.

OBJECTIVE: This study aims to analyse the environment encouraging C-section in Lebanon and to reveal approaches that could be adopted for the reduction of this practice, by considering the attitudes, opinions and actions of different stakeholders. METHODS: Semi-structured interviews were conducted with 20 selected key players, including hospital directors, midwives, insurance bodies, syndicates and scientific societies, ministries, international agencies, medical schools, media representatives and women's groups. In addition, a group discussion was conducted with 10 obstetricians. Semi-structured interviews were conducted with a convenience sample of 36 women who had a C-section within 4 months preceding the study. Data was analysed using the Policy Maker software version 2.3. RESULTS: Findings of the study point to the role of multiple factors in shaping the current practices related to C-section deliveries, among which are the organisation of the health care system, the dominance of the private sector, the lack of physician accountability, the minimisation of midwives' roles in the process and women's misconceptions about C-sections. CONCLUSIONS: Involvement of the diversity of players is important to change practices in maternity care in Lebanon, after considering their position and power. Different strategies making use of available opportunities to improve the current situation are discussed.
