Abstractobjectives Currently available vacuum devices used to assist women undergoing complicated labour are unsuitable for use in low-resource settings. The objective of this study was to evaluate the safety and feasibility of a new low-cost vacuum device, named Koohi Goth Vacuum Delivery System (KGVDS), designed for use in low-resource settings.methods A hospital-based, multicentre, prospective cohort study with no control group was conducted in Karachi, Pakistan. After training, KGVDS devices were made available for use by labour room staff at their discretion when instrumental delivery was indicated. Women to whom KGVDS was applied were followed from the start of labour until discharge. Feasibility was assessed in terms of successful expulsion of the foetal head following application of KGVDS and ease of use ratings. Safety was assessed by observing maternal and newborn post-delivery outcomes prior to discharge.results Koohi Goth Vacuum Delivery System was applied to 137 women requiring instrumental delivery, of whom 111 (81%; 95% CI = 74-88%) successfully expelled the foetal head assisted by KGVDS and 103 (75%) stated that they would agree to use KGVDS again. There were no serious maternal or neonatal injuries or infections related to KGVDS use. The mean score for 'ease of use' given by doctors and midwives using the device was 8 of 10.conclusions Koohi Goth Vacuum Delivery System was feasible and safe to use for assisting complicated deliveries in low-resource hospitals in this initial evaluation. Our results indicate that this new device may have the potential to improve birth outcomes in settings where most mortality occurs and that further evaluations should be conducted.keywords maternal health, low-resource setting

“…In developed countries, instrumental delivery is fairly common, with frequency of use varying between 1.5% and 26% (Wen et al . ; Hayman ). Vacuum extraction involves placing a suction cup on the undelivered foetal head and using a pumping system to create a vacuum, which allows the cup to attach to the foetal head.…”

“…Instrumental vaginal delivery, including ventouse (vacuum extraction) and forceps delivery, has been previously identified as a risk factor for maternal and fetal complications 28,29 . The risk of uterine rupture associated with instrumental vaginal delivery is unclear due to an absence of previous studies.…”

Objective Uterine rupture is a rare but a catastrophic event. The aim of the present study was to explore the risk factors for uterine rupture and associated neonatal morbidity and mortality among a cohort of Swedish women attempting vaginal birth in their second delivery.Design Population-based cohort study.Setting Sweden. Methods Swedish population-based registers were used to obtain information concerning demographics, pregnancy and birth characteristics, and neonatal outcomes. Logistic regression was used to analyse potential risk factors for uterine rupture and risk of neonatal mortality associated with uterine rupture. Odds ratios were used to estimate relative risks using 95% CI.Main outcome measure Uterine rupture and neonatal mortality in the second pregnancy.Results Compared with women who delivered vaginally in their first birth, women who underwent a caesarean delivery were, during their second delivery, at increased risk of uterine rupture (adjusted OR 41.79; 95% CI 29.73-57.00). Induction of labour, high ( ‡4000 g) birthweight, postterm ( ‡42 weeks) births, high ( ‡35 years) maternal age, and short (£164 cm) maternal stature were also associated with increased risk of uterine rupture. Uterine rupture was associated with a substantially increased risk in neonatal mortality (adjusted OR 65.62; 95% CI 32.60-132.08). ConclusionThe risk of uterine rupture in subsequent deliveries is not only markedly increased among women with a previous caesarean delivery but also influenced by induction of labour, birthweight, gestational age, and maternal characteristics.Keywords Caesarean section, cohort study, infant mortality, Sweden, uterine rupture, vaginal birth after caesarean.Please cite this paper as: Kaczmarczyk M, Sparén P, Terry P, Cnattingius S.

“…Continuous training to improve the skills and judgment of trainees in obstetrics is also an important factor. In a recent review 13 on instrumental deliveries, it was proposed that each patient should be assessed individually and the appropriate instrument used with the aim of reducing complication. Adherence to instrumental delivery guidelines will certainly help give the best service to patients.…”
