Evaluation of the ease of use and acceptability of an innovative device - the 'Episiometer', in ensuring an accurate mediolateral episiotomy: a pilot study.

The present study was undertaken at the Port Moresby General Hospital, Papua New Guinea, to evaluate the ease of use and acceptability of a perineal measuring device (Episiometer) for giving a correct length and angle of a mediolateral episiotomy. An Episiometer was placed on the perineum to guide the angle and length immediately before giving an episiotomy. A feedback survey was collected and the angle and length of the episiotomy were measured at the time of delivery and at 6 weeks postpartum.

Near-misses at the Port Moresby General Hospital: a descriptive study.

Background: The World Health Organization (WHO) defines 'maternal near-miss' as 'a woman who nearly died but survived a complication that occurred during pregnancy, childbirth or within 42 days of termination of her pregnancy'. With declining rates of maternal mortality, near-miss analysis is being examined in both developed and developing country settings for the assessment of obstetric care.

Aims: Over a 15-month period, details of cases that could be classified as 'near-misses' were collected at Port Moresby General Hospital (PMGH), to assess the practicality of collecting such data routinely and determine near-miss rates for the hospital.

Antepartum prediction of respiratory distress syndrome: a comparison of the shake test, the tap test and the turbidity test.

The shake test, the tap test and the turbidity test were evaluated to determine their accuracy in predicting lung function maturity, ie their ability to predict respiratory distress syndrome (RDS). The turbidity test was the most efficient with a sensitivity of 60%, a specificity of 97%, a positive predictive value of 82% and a negative predictive value of 92%. The shake test had a sensitivity of 40%, a specificity of 95%, a positive predictive value of 63% and a negative predictive value of 88%.

A case-control study of early neonatal deaths at the Port Moresby General Hospital to determine associated risk factors.

From June 1998 to December 1999, mothers of 150 babies who died in the early neonatal period and 150 controls whose babies did not die were studied. In multiple logistic regression analysis the following variables were positively associated with early neonatal deaths: lack of antenatal attendance, thick meconium staining of the liquor, male sex, very low birthweight and delivery at gestational age less than 34 weeks. Maternal betelnut chewing was negatively associated with neonatal deaths.
