Evaluation of a strict protocol approach in managing women with severe disease due to abortion.

AIM: To evaluate whether the introduction of a strict protocol approach based on the systemic evaluation of critically ill pregnant women with complications of abortion affected outcome. SETTING: Indigent South Africans managed in the regional and tertiary hospitals of the Pretoria Academic Complex. METHOD: Since 1997 a standard definition of severe acute maternal morbidity (SAMM) has been used in the Pretoria Academic Complex. All cases of SAMM and maternal deaths were entered on the Maternal Morbidity and Mortality Audit System programme. A comparison of outcome of severely ill women who had complications of abortion was made between 1997-1998 (original protocol) and 2002-2004 (strict protocol). OUTCOME MEASURES: The mortality index and prevalence of organ system failure or dysfunction. RESULTS: In 1997-1998 there were 43 women with SAMM who survived and a further 10 maternal deaths due to complications of abortion, compared with 107 women with SAMM and 7 maternal deaths during 2002-2004. The mortality index declined from 18.9% in 1997-1998 to 6.1% in 2002-2004 (p = 0.02, odds ratio 0.28, 95% confidence limits 0.10 - 0.79). Significantly more women had hypovolaemic shock in 2002-2004 compared with 1997-1998 (54.4% v. 35.8%, p = 0.04), but fewer women had immune system failure including septic shock (18.4% v. 47.2%, p = 0.0002) and metabolic dysfunction (0 v. 5.7%, p = 0.03) and there was a trend to less renal failure (10.5% v. 22.6%, p = 0.06) and cardiac failure (4.4% v. 13.2%, p = 0.08). CONCLUSION: The strict protocol approach based on systemic evaluation in managing critically ill pregnant women with complications of abortion, coupled with an intensive, regular feedback mechanism, has been associated with a reduction in the mortality index.     

Intrapartum-related birth asphyxia in South Africa--lessons from the first national perinatal care survey.

BACKGROUND: The recent amalgamation of data by users of the Perinatal Problem Identification Programme (PPIP) throughout South Africa has culminated in the publication of the Saving Babies report. OBJECTIVES: To determine the absolute rate of death from intrapartum-related birth asphyxia, and the contribution of intrapartum-related asphyxia to total perinatal mortality in South African hospitals, and to identify the primary obstetric causes and avoidable factors for these deaths. METHODS: The amalgamated PPIP data for the year 2000 were obtained from 27 state hospitals (6 metropolitan, 12 town and 9 rural) in South Africa. In PPIP-based audit, all perinatal deaths are assigned primary obstetric causes and avoidable factors, and these elements were obtained for all deaths resulting from intrapartum-related birth asphyxia. RESULTS: There were 123,508 births in the hospitals surveyed, with 4,142 perinatal deaths among infants > or = 1,000 g, giving a perinatal mortality rate of 33.5/1,000 births. The perinatal mortality rate from intrapartum-related birth asphyxia was 4.8/1,000 births. The most frequent avoidable factors were delay by mothers in seeking attention during labour (36.6%), signs of fetal distress interpreted incorrectly (24.9%), inadequate fetal monitoring (18.0%) and no response to poor progress in labour (7.0%). The perinatal mortality rates for metropolitan, town, and rural areas were 30.0, 39.4 and 30.9/1,000 births respectively. The contribution of intrapartum-related birth asphyxia to perinatal mortality in these areas was 10.8%, 16.7% and 26.4% respectively. CONCLUSION: The high rates of perinatal death from intrapartum-related birth asphyxia in South Africa are typical of those in underdeveloped countries, with the most serious deficiencies in rural areas. Most of these deaths are avoidable and the reduction of these rates presents an important challenge to providers of perinatal care in this country. Areas worthy of research and action include provision of mothers' waiting facilities in rural regions, improvements in fetal monitoring, partogram-based labour management, and the establishment of midwifery staffing norms for South African labour units.     

The effect of cigarette smoking on ovarian function and early pregnancy outcome of in vitro fertilization treatment

A retrospective analysis of the results of the first attempt at in vitro fertilization (IVF) treatment in 447 couples was performed by chart review. In 124 couples the female partners smoked cigarettes, and in 236 couples they did not. A total of 69 pregnancies (19.2%) were achieved, 50 in nonsmokers (21.2% per cycle), and 19 in smokers (15.3% per cycle). There were no significant differences in these cycles between the two groups in peak estradiol level achieved, the number of eggs retrieved, fertilization rate, or implantation rate. The incidence of spontaneous abortion was higher in smokers (42.1%) than in nonsmokers (18.9%). Consequently, the delivery rate per cycle of IVF was significantly lower in the smoking group (11 of 124, 9.6%) than in the nonsmokers (40 of 236, 17.0%). There was no effect when only the husband was a smoker. From these data, smoking appears to significantly reduce the chances of successful pregnancy after IVF treatment.     

Frequent fetal heart-rate monitoring for early detection of abruptio placentae in severe proteinuric hypertension

Abruptio placentae occurred in 16 of 132 patients with severe pre-eclampsia who were admitted to an obstetric high-risk ward before 34 weeks' gestation. These 16 patients were compared with those who did not develop abruptio placentae. Systolic and diastolic blood pressure levels, proteinuria and birth weights did not differ significantly between the two groups. Apgar scores were significantly lower in the abruptio placentae group. There were 6 intra-uterine and 2 neonatal deaths in the abruptio placentae group (50% perinatal mortality (PNM] and 3 intra-uterine and 16 neonatal deaths in the other group (18% PNM). Four patients with abruptio placentae presented with abnormal fetal heart-rate patterns and 8 with abdominal pain. No warning signs were present in 3 patients and the fetal heart-rate pattern before delivery was not available in 1 patient. Abnormal fetal heart-rate patterns were present in 5 of the 8 patients who presented with pain. Abruptio placentae occurring in patients with severe proteinuric hypertension carries a high PNM. Frequent monitoring of the fetal heart rate sometimes helps to diagnose fetal distress before the clinical signs of abruption become apparent.

Treatment of spermagglutination with proteolytic enzymes. I. Sperm motility, vitality, longevity and successful disagglutination

The treatment of antibody-mediated spermagglutination by corticosteroidtherapy has a high incidence of side-effects and sperm washingis often followed by re-agglutination. The possibility of enzymaticdisagglutination was therefore investigated. In the first partof the study the effects of four proteases on sperm motility,vitality and longevity were evaluated. Subtilisin had prohibitivelydetrimental effects even at 10 U/ml. However, chymotrypsin (500U/ml), trypsin (500 U/ml) and papain (50 U/ml) had no adverseeffects. In the second series of experiments one or more ofthese latter three enzymes was found to disagglutinate spermatozoawhich had previously been incubated with sperm-agglutinatingantibody-positive sera in 87% of cases. Although further investigationis required, enzymatic disagglutination may be beneficial forthe treatment of immunologically mediated spermagglutination.     

Safety and tolerability of combined treatment with moclobemide and SSRIs: a preliminary study of 19 patients

Nineteen major depressed patients, resistant to previous pharmacotherapies, were treated by the addition of moclobemide (up to 600 mg/day) to paroxetine or fluoxetine (20 mg/day) for 6 weeks in an open study to assess the adverse events and tolerability. There were 77 emergent events, insomnia, headache, nausea and dizziness being the most common. Many events were rated as severe. The high rate of adverse events suggests that there may be clinically significant interactions between moclobemide and SSRIs. However, the uncontrolled data on effectiveness is encouraging and the combination deserves further attention as a strategy for treating intractable major depression.     

The introduction of umbilical cord lactate measurement and associated neonatal outcomes in a South African tertiary hospital labor ward

Purpose: To investigate the utility of umbilical artery (UA) lactate measurements in a South African hospital for assessing intrapartum care and predicting neonatal outcomes.

Materials and methods: From 3 March–12 November 2014, we conducted a prospective cohort study of UA lactate levels at Kalafong Hospital, Pretoria, South Africa. Following birth, a UA blood sample (<0.5uL) was taken from a double-clamped segment of cord and the lactate measured. Maternal and neonatal characteristics and outcomes were recorded.

Results: During the study, there were 4668 deliveries; including 1091 emergency cesarean and 154 instrumental deliveries. A lactate was recorded for 946 deliveries (20.3%). 190 babies required neonatal resuscitation, with an optimal cutoff for lactate of 5.45?mmol/L (sensitivity 68%, specificity 72%). 124 babies required nursery admission with the optimal cutoff for lactate 4.95?mmol/L (sensitivity 61%, specificity 59%). 55 babies had an Apgar score <7 at 5?min and the optimal lactate for this outcome was 5.65?mmol/L (sensitivity 64%, specificity of 69%).

Conclusions: Umbilical lactate can be used in a middle-low resource setting as a measurement of intrapartum hypoxia, with reasonable sensitivity and specificity for the prediction of, or need for, resuscitation, admission to the nursery, and low Apgar scores.
