Coagulation screening before epidural analgesia in pre-eclampsia

A questionnaire survey of current practice at a small cross-section of obstetric units, covering 22% of all United Kingdom deliveries, revealed a marked lack of standard practice regarding requests for coagulation screens on pre-eclamptic patients who require epidural procedures. A retrospective audit was therefore carried out on 434 coagulation screens requested for pre-eclamptic patients in whom epidural analgesia might have been considered. Borderline abnormalities of coagulation were found in only 10 patients (2%). Platelet counts of less than 150 x 10(9)/litre were present in 28% of cases. 'Significant' thrombocytopenia (less than 100 x 10(9)/litre) and all coagulation abnormalities were only encountered in severe pre-eclampsia (diastolic blood pressure of greater than 110 mmHg and proteinuria of + + or greater). Furthermore, coagulation abnormality was always associated with a reduced platelet count (mean, 97 x 10(9)/litre). This study would therefore support anaesthetic practice which restricted any requests for coagulation testing to severe pre-eclamptic patients only. For these patients first line testing could be limited to a platelet count.     

Urinary tract injuries during obstetric intervention

A retrospective case record review of obstetric urinary tract injury in the Grampian region from 1976 to 1993 identified 16 cases of bladder injury (0.1 per 1000 deliveries, 1.4 per 1000 caesarean sections and four cases of ureteric injury (0.03 per 1000 deliveries, 0.27 per 1000 caesarean sections). Diagnosis of bladder injury was immediate, but of ureteric injury often delayed. Although the injury rates are lower than previously reported and previously reported risk factors not confirmed, this audit has resulted in guidelines for junior staff, compliance with which will be monitored, and every case of urinary tract injury will be reviewed.     

Reversal of sterilisation by the railroad technique

Objective To show that a simple, easily learned and relatively inexpensive method of reversal of sterilisation provides good results.
Design Retrospective observational study.
Setting An NHS Trust Hospital.
Sample Sixty-seven women aged 19 to 39 years who underwent reversal of sterilisation between January 1984 and December 1993.
Main outcome measures Pregnancy rate following reversal; rate of ectopic pregnancy.
Results Thirty-four women (51%) had intrauterine pregnancies after reversal of sterilisation; intrauterine pregnancy rate in women who had been sterilised with rings or clips was 64%. Five women (7.5%) had ectopic pregnancies.
Conclusion This technique provides results that compare favourably with those of microsurgery. It offers hope to couples who do not meet the restrictive criteria for microsurgery and in vitro fertilisation and should appeal to purchasing authorities.     

Estimating the chance of an inadequately immunised child getting pertussis

Before informed advice can be given to parents and health care workers about the need for pertussis immunisation, an estimate of the risk of inadequately immunised children contracting pertussis is needed. The study reported here was conducted because the literature contains no such estimates of risk. Analysis was made of a county's Notification of Disease Reports. Computation was carried out of age-specific annual notification rates of pertussis amongst adequately and inadequately immunised children. It was found that inadequately immunised one-year-old children probably have more than a one in six chance of developing pertussis before age ten.     

Neonatal mortality amongst Scottish preterm singleton births (1985–1994)

Objective To provide a valid estimate of singleton neonatal mortality based on birthweight and gestational age at delivery.
Design Record linkage of maternity data and neonatal mortality data.
Setting Scotland, UK.
Population All singleton preterm deliveries from 24 to 36 weeks inclusive between 1985 and 1994.
Main outcome measure Neonatal death.
Results There were 625,646 liveborn singleton deliveries over the study period, of which 33,912 were preterm (5.4%). The overall neonatal mortality in the preterm group was 41/1000 and the data have been presented by both gestational age and birthweight. The neonatal mortality rate fell with advancing gestation from 795/1000 live births at 24 weeks to 9/1000 live births at 36 weeks and was higher at the extremes of birthweight for a given gestational age. There was a significant increase in the proportion of babies delivered iatrogenically over the study period (χ test for trend   P < 0.001  ).
Conclusion This is the largest recent series to consider neonatal mortality using both birthweight and gestational age. These figures will be of use in obstetric management when elective preterm delivery is considered, and for providing prognostic guidance following preterm delivery.     

The nurse''s decision-making process and the implementation of psychogeriatric nursing in a mental hospital

This study looks at the psychogeriatric nurse's decision-making process and on this basis seeks to describe the implementation of psychogeriatric nursing in a mental hospital. The subjects consist of 26 nurses working on the psychogeriatric wards of one hospital. The data were collected using a questionnaire (n = 26), a 1-week time-usage analysis, content analysis of nursing plans (n = 56), and observation of planning meetings (n = 15). The results for different phases of the decision-making process suggested that nurses had little difficulty with the identification of problems. Data collection tended to concentrate on the physical side of nursing work. The setting of explicit targets for nursing care proved to be difficult. The vast majority of the nurses (85%) felt that decision-making on different nursing alternatives was only moderately or not at all successful. Over half of the nurses felt that their ability to evaluate the outcome of treatment and nursing was either satisfactory or poor. Time-usage analysis indicated that the nurses had frequent interaction with their patients in connection with basic care, although the nurses themselves did not regard this part of their work as active interaction with the patient.
