RESUMO
OBJECTIVE: To evaluate whether the traction force indicator in a ventouse device gave an accurate estimation of the force applied. METHODS: The study was carried out at the Derby City Hospital. An estimate of measurement errors was made by analyzing the standard deviation of the residuals for 30 Kiwi OmniCup devices (Clinical Innovations, Abingdon, Oxfordshire, England) and a standard industrial spring balance. RESULTS: The measurement errors for the traction forces were very small and acceptable for the OmniCup. The overall estimate of measurement errors was 0.45 kg (1.35 lb). CONCLUSION: The overall measurement error for the traction force indicator of the OmniCup was found to be very small. Injuries associated the ventouse, such as cephalohematomas and subgaleal hemorrhages, may be minimized if the recommended limits for a safe traction force are not exceeded.

Abdominal and vaginal hysterectomy are common operations for benign gynaecological conditions. Though safe operations, they are not without complications. Good medical practice requires that patients be fully counselled regarding risks involved in undergoing medical interventions. This can only be done by regular review of local practice and comparison with national and international standards. We have reviewed 502 case notes of patients who have undergone a hysterectomy for benign conditions over an 18-month period.

This review summarizes the options available for the management of postpartum haemorrhage when ecbolic agents have failed to control the bleeding and an obvious rectifiable problem such as retained placental fragments, lower genital tract trauma, uterine inversion or uterine rupture have been excluded or dealt with. The review covers the range of surgical options but gives an in-depth explanation of the more recent developments such as uterine brace sutures, the use of the Sengstaken-Blakemore tube and embolization procedures.
