The maternal deaths occurring in the Kilimanjaro Christian Medical Center (KCMC), which serves as a supraregional reference hospital for the 5 regions of Northern and Central Tanzania, are reviewed for the 1971-1977 period and avoidable factors are discussed. All deaths occurring within the hospital during pregnancy or the first 6 weeks of the puerperium were included in this survey. Postmortem examination was performed in 35% of the cases. In the remaining cases the diagnosis was made on clinical grounds. During the period under review, there were 10 deaths among 83 cases, a mortality of 12%. The major cause of rupture was obstructed labor associated with a contracted pelvis or abnormal lie. 25% of the patients had had a previous cesarean section scar give way. 2 other deaths were attributed to anesthetic accidents and 1 was probably due to pulmonary embolism. The primary cause of death in the 7 remaining cases was hemorrhage (4) and sepsis (3). If deaths from ruptured uterus are to be avoided, early diagnosis is essential. 1044 cases of moderate and severe EPH gestosis (preeclampsia) were treated in KCMC during the period under review together with 54 cases of eclampsia. There were 5 deaths among the patients with eclampsia, a mortality of 9%. In addition to the 11 sepsis deaths there were 3 others included among the cases of ruptured uterus. There were 4 cases of septic abortion and 3 of those admitted to criminal interference. Preexisting anemia was a complicating factor in 5 cases, all of whom died within 15 minutes of arrival. There were 4 deaths among 251 cases of ruptured ectopic pregnancy. There were 10 deaths associated with cesarean section among 1271 sections peformed during the period under review. Deaths from associated diseases included the following: enterocolitis (12 deaths); renal and hypertensive disease (4 deaths); cardiac disease (2 deaths); anemia (2 deaths); malaria (2 deaths); tuberculous meningitis (2 deaths); and miscellaneous associated conditions (11 deaths).

This study attempts to collect reliable data on maternal deaths, estimate maternal mortality rate for the western state of Nigeria, and identify major causes of maternal deaths in the state. Standardized questionnaires were sent to randomly selected medical institutions (5 specialist hospitals and 25 general/district hospitals) in the state; only 23 institutions (4 specialist and 19 district/general hospitals) completed the questionnaires. The results show that maternal mortality ranged from 0/1000-13.3/1000 total births in 1972 and 0/1000-11.0/1000 total births in 1973; overall maternal mortality rate was 3.8/1000 in 1972 and 4.7/1000 in 1973. Mortality was higher among unbooked patients, accounting for 71.2% and 66.4% of total deaths in 1972 and 1973. Hemorrhage (antepartum and postpartum), obstructed labor (uterus unruptured and ruptured), eclampsia and anemia of pregnancy accounted for over 80% of total deaths. Nonobstetric causes of maternal deaths including poisoning, infective hepatitis, meningitis, encephalitis, bronchial asthma, hypertension, and pulmonary embolism. The major causes of death in this series were preventable. Maternal mortality is associated with age, parity, and past reproductive and medical history. The high maternal death rate in this study is compounded by nonutilization of available medical services by pregnant women most especially for antenatal care, the lack of basic essential life-saving facilities (e.g., for blood transfusion), lack of adequate transportation system, failure of medical/nursing personnel to refer patients early to specialist hospitals, and relative lack of obstetric services both in quality and quantity all over the country. Better coordination and integration of health services are needed, as are nationwide data collection of maternal death statistics, publication of periodical reports, and establishment of standards for overall maternity care.

There were 37 maternal deaths among the 109,221 livebirths registered during the period 1977-86 in Bahrain, Arabian Gulf. The maternal mortality rate was 33.9/100,000 for the 10-year study period; however, disaggregation reveals a decline in this rate from 42.3/100,000 in 1977-81 to 26.9/100,000 in 1982-86. This decline presumably reflects streamlining of the Ministry of Health's maternity services, including a central maternity hospital with all modern facilities that serves as a referral center for all of Bahrain, 2 peripheral hospitals with provision for blood transfusion and surgical deliveries, and 3 maternity units managed by fully qualified midwives. About 80% of deliveries are covered by these maternity services; only 2.5% of deliveries occur in the home. Despite this highly developed maternity care system, 18 of the maternal deaths were due to direct obstetric cause: hemorrhage, 7; pre-eclampsia and eclampsia, 5; abortion septicemia, 2; bowel perforation during cesarean section, 1; thromboembolism, 2; and amniotic fluid embolism, 1. The causes of the 19 indirect maternal deaths were: pulmonary embolism, 5; infection, 7; cardiac failure, 2; cerebrovascular accident, 2; pulmonary hypertension, 1; and uncertain, 2. Of interest is the finding that sickle cell disease was the underlying cause of maternal death in 12 of the 37 deaths in this series. Sickle cell disease was implicated in 3 of the deaths from hemorrhage, all 5 deaths from pulmonary embolism, 2 deaths from septicemia, and the 2 cases of cardiac failure. In this series, 50% of the patients with sickle cell disease had thromboembolic crises following treatment of anemia with packed cell transfusion. Blood transfusion, especially of packed cells, should be given with caution to these patients since it may precipitate vaso-occlusive crisis by increasing blood viscosity. Since sickle cell disease represents a high risk during pregnancy in this Arab population, such patients should have frequent prenatal check-ups and deliver in a well-equipped hospital.

Sixty-eight deaths during pregnancy, parturition and puerperium were recorded in Sweden during the years 1971-80, giving a maternal mortality of 6.6 per 100,000 live births. The figures for abdominal delivery and vaginal were 45.0 and 2.5 per 100,000 live births respectively. Amniotic fluid embolism, pulmonary embolism and hemorrhage were the main causes of death within 24 hours after delivery, while pre-eclampsia/eclampsia and sepsis were predominant during the rest of the puerperium. Age and parity are highly important risk factors. Presumed avoidable factors were identified in 19% of the cases. 9% of the deaths were related to unwanted pregnancy.

Maternal mortality was examined in a semi-urban Nigerian community over a 10-year period. Maternal mortality was defined as death occurring as the direct result of childbearing and measured per 1000 births. Abortions at below 20 weeks gestation were excluded. From 1966 to 1975, there were 90 maternal deaths out of 13,182, a rate of 6.8/1000. The hospital records of the Baptist Medical Center, located in the western part of Nigeria, were carefully reviewed and cross-checked with obstetric statistical records. Only 13 of the deaths occurred in hospitalized patients. 78 (80%) were due to direct obstetric causes; 12% were from nonobstetric causes. Anemia due to blood loss was the leading casue of death, accounting for 30, or 33%, of the deaths. Anemia, with or without congestive heart failure accounted for 7 deaths. Infection was responsible for 5 deaths. Ruptured uterus, preeclampsia, and eclampsia occurred in equal percentages, 10-11%. Indirect obstetric deaths, such as sudden death, accounted for 10 deaths. 50% of these were anesthetic deaths; the remainder were due to pulmonary embolism. Sickle cell intrapartum crisis was the cause of 1 death. Associated causes included featured pneumonia, nephritis, hepatitis, meningitis, enteritis, and cerebrovascular accident. Parity ranged from 0-11. 25 babies were salvaged in this series. Prevention continues to be the cornerstone in improving maternal mortality figures in developing countries. The Baptist Medical Center's model for providing maternal care is described briefly and is identified as responsible for the encouraging decline in the maternal mortality rate.

During 1983-1992 in Turkey, 17 maternal deaths occurred out of 100,531 live births at the Zubeyde Hanim Maternity Hospital in Ankara for a maternal mortality ratio (MMR) of 16.9/100,000 live births. Hemorrhage (41.2%) and pulmonary embolism (35.3%) were the leading causes of maternal death. Cases referred to the hospital after home deliveries accounted for 57% of the hemorrhage-related deaths. Other causes of maternal death were eclampsia (11.7%), puerperal infection (5.9%), and heart failure attributed to rheumatic heart disease (5.9%). The MMR fell over time from 22.6 (1983-1984) to 12.8 (1991-1992). Women younger than 20 and those 35 and older suffered from the highest MMRs. MMR increased with parity (8 for primigravida, 10 for parity 1-2, 27.3 for parity 3-4, and 62.1 for parity =or 5). Cesarean delivery was associated with a higher MMR than vaginal delivery (44.7 vs. 14.1). This association was likely a result of pregnancy complications that led to a cesarean section rather than the cesarean section itself.

Between 1969 and 1991 there were 166,410 births in Southern Israel with 13 maternal deaths (7.8/100,000). In the Jewish population there were 119,130 deliveries with 7 maternal deaths (5.9/100,000), and the Bedouins had 47,280 deliveries with 6 maternal deaths (12.7/100,000). Prenatal care was an important preventive factor. 7 maternal deaths occurred among 151,088 women who had received prenatal care (4.6/100,000), whereas 6 such deaths occurred among 15,322 without prenatal care (39.1/100,000) (P value 0.0005). Ten of the 13 women who died were over 24 years old. Eight of the 13 patients were multiparous. Live births occurred in 6 patients and stillbirths in 5 patients. Hemorrhage, preeclampsia-eclampsia and pulmonary embolism were the leading causes of maternal death.

The aim was to study the numbers and causes of Maternal Mortality in the Irish Republic in the years 1989-1991, inclusive and publish sufficient detail to allow for international comparative studies. Maternal Deaths were identified via Death Certificates, Coroners' Reports and Hospital Annual Reports. Details of these deaths were then obtained from relevant clinicians and analysed by the authors with further consultation with involved parties, if necessary. There were nineteen deaths notified in the three year period. According to ICD9 these were classified as five direct, seven indirect, and seven fortuitous deaths. Amongst the five Direct deaths, two were associated with amniotic fluid embolism, and one with each of eclampsia, septicaemia and pulmonary embolism, a direct maternal mortality rate of 3.2 per 100,000 births.

A study of 165 maternal deaths at the University of Benin Teaching Hospital, Benin City over a 13-year period (from April 1, 1973 to December 31, 1985) is presented. All patients' case files were recovered from the central records library and each case file was carefully analyzed. With a total delivery of 29,324, the maternal mortality rate, inclusive of death from abortion, was 563/100,000 deliveries. There was a general increase in maternal mortality rate with age and this became alarming from 35 years. There was an equally high mortality rate among teenagers, mainly accounted for by illegally induced abortion. Indeed, abortion accounted for 72% of teenage mortality. A statistically significant association between maternal deaths and parity (p, 0.001) was observed. The most important causes of death were hemorrhage with a total of 26 out of 42 deaths, sepsis, and abortion. Other important causes were hypertensive disorders such as eclampsia, liver and respiratory disease, anemia, trophoblastic diseases, caesarean sections, and acute renal failure. Additional causes of maternal deaths include tetanus, sickle-cell disease, anesthetic death, drug reactions, pulmonary embolism, acute pyogenic meningitis, typhoid disease, urinary bladder tumor, acute lymphoblastic leukemia, and carcinoma of the breast thyroid. Factors identified with these deaths included such health services factors as deficient medical treatment of obstetric complications, lack of adequate personnel at primary and secondary health care levels, lack of access to maternal health services, and consequently, lack of prenatal care. Extreme reproductive age, grandmultiparity, and unwanted pregnancies, especially among teenagers, also contributed to maternal deaths. Overhaul of the maternal health care services at national level to include organization of such programs as provision of adequate blood transfusion facilities, prompt treatment of infections, early referrals of patients at risk to secondary and tertiary health centers, intensified family planning programs, and liberalization of abortion laws are recommended in order to reduce the unacceptably high maternal mortality.

The objectives of this study are to determine the trend of maternal mortality at the University of Ilorin Teaching Hospital, to identify the causes of death, and to identify ways of minimizing the frequency of preventable deaths. Analysis of 75 cases of maternal deaths seen over 3 1/2 years (January 1983-June 1986) was conducted. During this period, there were 26,905 births, giving a maternal mortality rate of 279/100,000. 84% of the deaths were due to direct causes while the remaining 16% were classified under the indirect and pregnancy related categories. The main direct causes of death include hemorrhage (35.6%), septicemia (24.7%), and anemia (13.7%). Other direct obstetric causes include eclampsia, anesthetic death, hemoglobinopathy, and ruptured uterus. The most important indirect causes were native drug intoxication (6.8%), fulminant hepatitis (5.5%), and pulmonary embolism (2.7%). The maternal mortality was highest in the age ranges 25-29 years (31.5%). Median age and parity were 27 years and 4.5 respectively. While the maternal mortality rate of 2.8/1000 is an improvement over the previous years' (1972-1982) record of 4.3/1000, it is still unacceptable. The majority of these deaths could have been prevented if delivery had occurred in a well equipped hospital where blood transfusion and surgical facilities are available, if sterile manipulations for pregnant women had been employed, if appropriate antenatal care was available, and if specialist anesthetist services were accessible. Recommendations to reduce the maternal mortality rate include improved education and training of traditional birth attendants, improved immunization of women against tetanus, and increased community involvement through education. Furthermore, policy makers must set new priorities such as encouraging greater investment in improving clinics and hospital facilities, improving access to contraception, increasing awareness of the magnitude of the problem and encouraging community leadership and action.
