Rising trend and indications of caesarean section at the university of Maiduguri teaching hospital, Nigeria

OBJECTIVE To determine the trend and indications for the use of caesarean delivery in our environment. METHOD A retrospective review of the caesarean sections performed at University of Maiduguri Teaching Hospital from January 2000 to December 2005 inclusive. RESULTS During the study period, there were 10,097 deliveries and 1192 caesarean sections giving a caesarean section rate of 11.8%. The major maternal indications were cephalopelvic disproportion (15.5%), previous caesarean section (14.7%), eclampsia (7.2%), failed induction of labor (5.5%), and placenta previa (5.1%). Fetal distress (9.6%), breech presentation (4.7%), fetal macrosomia (4.3%), and pregnancy complicated by multiple fetuses (4.2%) were the major fetal indications. The caesarean section rate showed a steady increase over the years (7.20% in 2000-13.95% in 2005), but yearly analysis of the demographic characteristics, type of caesarean section, and the major indications did not reveal any consistent changes to account for the rising trend except for the increasing frequency of fetal distress as an indication of caesarean section over the years, which was also not statistically significant (c[2] =8.08; P=0.12). The overall perinatal mortality in the study population was found to be 72.7/1000 birth and despite the rising rate of caesarean section, the perinatal outcomes did not improve over the years. CONCLUSION Trial of vaginal birth after caesarean section in appropriate cases and use of cardiotocography for continuous fetal heart rate monitoring in labor with confirmation of suspected fetal distress through fetal blood acid--base study are recommended. A prospective study may reveal some of the other reasons for the increasing caesarean section rate.

Obstructed labour: a public health problem in Gombe, Gombe State, Nigeria

This study reviewed retrospectively the cases of obstructed labour as seen at the specialist Gombe Hospital (SHG), Gombe State, over a period of 5 years. The incidence of obstructed labour was 4.0%. There was a progressive decline in the time trend over the study period. About 80.3% of the patients were unbooked emergencies and 99.5% of them had been in labour elsewhere before presenting at the hospital. The leading cause of obstructed labour was cephalopelvic disproportion (83.0%). Caesarean section (72.2%) was the most common method of delivery. Puerperal sepsis was the most frequent morbidity. However, the longest duration of hospital stay was as a result of a bedsore. The maternal mortality for cases of obstructed labour was 7605/100 000 and the perinatal mortality was 628/1000 births. The study aims to reinstate public interest in this health problem and offers suggestions on how to curb this human tragedy.

Trends in maternal mortality in a tertiary institution in Northern Nigeria

OBJECTIVE To look at the trends in maternal mortality in our institution over 5 years. METHODS Records of 112 maternal deaths were retrospectively reviewed to determine the trends and the likely direct cause of each death over the study period. RESULTS There were a total of 112 maternal deaths, while 3931 deliveries were conducted over the 5-year period. The maternal mortality ratio (MMR) was 2849/100,000 deliveries. The highest MMR of 6234/100,000 was observed in 2003, with remarkable decline to 1837/100,000 in 2007. Eclampsia consistently remained the leading cause, accounting for 46.4% of the maternal deaths, followed by sepsis and postpartum hemorrhage (PPH) contributing 17% and 14.3%, respectively. There were no statistically significant differences in the corresponding percentages of maternal deaths between various age groups (chi2=6.68; P =0.083). Grandmultiparas accounted for a significant proportion of maternal deaths as compared to low parity, with chi2=10.43; P =0.00054. Lack of seeking antenatal care (unbooked) and illiteracy were observed to be significant determinants of maternal mortality (chi2=64.69, P =0.00000; and chi2=18.52, P =0.0000168, respectively). CONCLUSION In spite of decrease in the maternal mortality ratio over the years, it still remains high, with eclampsia persistently contributing most significantly. Community enlightenment on the need to avail of antenatal care and hospital delivery services, and improvement in the quality of skilled maternity care will, among other factors, drastically curtail these preventable causes of maternal death and reduce MMR.

A 5-year review of maternal mortality associated with eclampsia in a tertiary institution in northern Nigeria

OBJECTIVE To determine the incidence of maternal mortality associated with eclampsia and to determine how socio-demographic and clinical characteristics of the women influence the deaths. METHODOLOGY Records of 52 eclampsia-related mortalities from January 2003 to December 2007 were reviewed, retrospectively. Their social demography, mode and place of delivery, time of eclampsia, and fetal outcome were extracted for analysis. RESULTS Eclampsia accounted for 52 (46.4%) of the 112 total maternal deaths recorded within the 5-year period, with case fatality of 22.33%. Age group <20, 20-29 and above 30 all had similar case fatality rate of 22.1%, 23.8% and 26.7%, respectively. Those who were experiencing their first deliveries have the worst deaths recording 42.5% of the case fatality in that category. As expected, unbooked had a higher case fatality of 24.0% compared to 15% among book cases, while those with formal education also had more death (22.3% case fatality) as compared to 3.3% among those who had some form of formal education. Antepartum eclampsia was the cause in 50% of the death, 11 (21.2%) of the pregnancies were not delivered before their death, while 18 (34.6%) were stillbirth. CONCLUSION Eclampsia still remains the major cause of maternal mortality in this region resulting from unsupervised pregnancies and deliveries. There is need to educate and encourage the general public for antenatal care and hospital delivery.

Anaemia in pregnancy at booking in Gombe, North-eastern Nigeria

Summary Anaemia in pregnancy is an important reproductive health problem associated with increased maternal and perinatal morbidity and mortality. This study was undertaken to determine the prevalence of anaemia in pregnancy at booking in Gombe, North-eastern Nigeria. A cross-sectional study of 461 women attending the antenatal clinic was carried out. Anaemia in pregnancy was defined as a packed cell volume (PCV) of <30%. The capillary technique was used for the estimation of the PCV. The biosocial characteristics (age, parity and social class); and gestational age at booking were obtained and analysed. Of the 461 pregnant women studied, 239 were anaemic, a prevalence of anaemia at booking of 51.8%. The majority of these patients, 67.4%, were mildly anaemic, 30.5% were moderately anaemic while only 2.1% had severe anaemia. Most, 316 (68.5%) of the women booked in the second trimester while only 3.0% booked in the first trimester. There was no relationship between parity and anaemia in pregnancy in this study The majority of the women, 293 (63.5%) were in the lower social class. Because the majority of the anaemic gravidae are in the low social class, provision of haematinics at little or no cost will go a long way towards reducing the high prevalence of anaemia in pregnancy. In the long run, educational and economic empowerment of the women is the key to reducing the overall prevalence of anaemia to the barest minimum.

Prevention of mother-to-child transmission of HIV at Maiduguri, Nigeria

The human immunodeficiency virus (HIV) can be transmitted vertically through the placenta in utero, during labour and delivery and through breast milk. In Nigeria, about 5.8% of women attending antenatal clinics were HIV infected as of December 2002. It was projected that by the end of the year 2002, there were about 849 000 orphans resulting from AIDS and about 755 000 established paediatric AIDS in this country. Interventions to prevent mother-to-child transmission of HIV include voluntary counselling and testing (VCT), administration of antiretroviral drugs (ARV), modification of obstetric practices and infant feeding options in HIV infection. Over the period July 2002 – June 2003, 262 pregnant women received VCT at the antenatal clinic of the University of Maiduguri Teaching Hospital, and 207 (79%) agreed to be tested. Thirty-one (11.8%) were HIV positive. The majority of the HIV positive mothers received nevirapine in labour while 35% had combination ARV drugs in pregnancy. All the infants received nevirapine suspension within 72 hours of delivery. Expensive and slow testing facilities, insufficient and inconsistent counsellors, lack of ARV drugs for both mother and baby as well as unaffordable caesarean delivery were some of the constraints being faced at this centre. It is recommended that the governments at various levels should show more commitment to the programme of preventing mother-to-child transmission of HIV.

Knowledge and Attitude to Cervical Cancer Screening Among Women in Maiduguri, Nigeria

Five hundred women were studied to determine their knowledge of cervical cancer. Less than 10% of the women were aware of the disease or its symptoms. Even fewer were aware of cytological screening, the good results obtained in the premalignant stage and early invasive stages of the disease. Simple explanation showed a good recall at 4-6 weeks. At that time women would accept screening and understood its importance. This study shows clearly that education must precede a screening programme if it is to succeed.

Hydatidiform mole as seen in a university teaching hospital: A 10-year review

Summary Hydatidiform mole (HM), is a known cause of early pregnancy wastage and has the risk of malignant potential. This is a retrospective study of 71 patients who were managed for hydatidiform mole at the University of Maiduguri Teaching Hospital, (UMTH) Maiduguri over a 10-year period, from January 1996 to December 2005, inclusive. The objective of the study was to determine the incidence, risk factors, clinical presentations and histological types of HM. Case records of 71 histologically confirmed HM were studied. Their sociodemographic characteristics, clinical presentations and histology reports were obtained and analysed. The institutional incidence of molar pregnancy was 3.8/1,000 deliveries. Histological findings showed partial mole in 51 (71.8%) cases and complete mole in 20 (28.2%) cases. The peak age-specific incidence rate was 17.5 years. The leading presenting clinical feature was abnormal vaginal bleeding seen in 100%. No case of invasive mole was found. Maternal complications included severe haemorrhage requiring blood transfusion (30.0%) and infections (15.5%). There was no maternal death. In conclusion, the incidence of partial hydatidiform mole was found to be higher than that of complete variety in our environment and the identified risk factors were young age, low parity and previous history of HM.
