Fulltext Outcome of forceps delivery versus vacuum extraction--a review of 200 cases

Achanna S, Monga D

Singapore Med J, 1994 Dec;35(6):605-8.

The outcome of 100 patients undergoing instrumental delivery with vacuum extractor is compared with that of 100 women delivered with the aid of obstetric forceps. Forceps deliveries were more commonly associated with maternal birth canal trauma (including episiotomy) whilst vacuum extractor carried higher odds of the neonate developing jaundice. Apart from these, there were no significant differences between these two groups in terms of maternal morbidity, neonatal trauma and morbidity and ultimate outcome (success with the type of instrument used). We conclude that with meticulous handling of the instrument and with an appropriate decision on the indication and the type of instrument used, the maternal and neonatal outcome could be equally good with the use of either instrument.

Kiwi Omnicup versus Malmstrom metal cup in vacuum assisted delivery: a randomized comparative trial

J Obstet Gynaecol Res, 2008 Jun;34(3):350-3.

PMID: 18686348

AIM: To compare the success, clinical outcomes, and maternal and neonatal complications between the Kiwi Omnicup and the Malmstrom metal cup in vacuum assisted delivery.

METHODS: This was a prospective randomized comparative trial. Women who required vacuum assisted vaginal delivery were randomized into the Kiwi Omnicup (KO) group and the Malmstrom metal cup (MM) group. The vacuum assisted deliveries were conducted according to hospital protocol. Details of the procedure and delivery outcomes including success and complications were analyzed.

RESULTS: One hundred and sixty-four women were recruited - 85 were assigned to vacuum assisted delivery using the KO and 79 the MM. One hundred percent delivery success was achieved with no significant differences between the two instruments in terms of maternal morbidity (P = 0.66). Six women in the MM group sustained post delivery complications in comparison to five in the KO group. Three babies were diagnosed with birth asphyxia in each group. More babies in the MM group were admitted to the Neonatal Intensive Care Unit (NICU) (10 babies versus 5 babies) and suffered complications (14 versus 12 babies), compared to the KO group, although the difference was not statistically significant. There were no intrapartum or neonatal deaths and of those admitted to the NICU, all were discharged within a week without any serious consequences.

CONCLUSION: Kiwi Omnicup is an effective alternative to the currently available Malmstrom metal cup for vacuum assisted delivery with no increase in maternal or neonatal morbidity or mortality.

Fulltext Subaponeurotic haemorrhage in Malaysian neonates

PMID: 2392696

In a 30-month prospective study, between January 1987 and June 1989, 101 of 64,424 Malaysian neonates (1.6 per 1000 livebirths) born in the Maternity Hospital, Kuala Lumpur were found to have subaponeurotic haemorrhage shortly after delivery. The incidence was highest in neonates weighting 4000 gm or more. There was no significant difference in incidence of this condition in neonates of different ethnic origins. Hypoprothrombinemia was present in only 5/101 (5.0%) of the affected neonates. Sixty seven (66.3%) of the neonates with subaponeurotic haemorrhage had history of trial of vacuum extraction. The incidence of subaponeurotic haemorrhage was significantly higher in neonates delivered by vacuum extraction than by other modes of delivery in this hospital (41.4 per 1000 livebirths in neonates delivered by vacuum extraction versus 1.0 per 1000 livebirths in neonates delivered by other modes). Those neonates who developed subaponeurotic haemorrhage without trial of vacuum extraction had a history of either prolonged labour or difficult delivery. Thirty-three (32.7%) of the neonates with subaponeurotic haemorrhage developed anaemia which required blood transfusion and 3/33 (9.1%) were in shock. Fifty seven (56.4%) of the neonates with subaponeurotic haemorrhage developed hyperbilirubinemia due to the haemorrhage. Four (7.0%) of them had severe unconjugated hyperbilirubinemia which required exchange transfusion. The results of this study suggest that subaponeurotic haemorrhage in Malaysian neonates was commonly associated with vacuum extraction and was not a benign condition.

Fulltext Neonatal posterior fossa haemorrhage associated with vacuum extractor

Ghani AR, Prakash RG, Abdullah J

Med J Malaysia, 2006 Mar;61(1):100-2.

PMID: 16708744 MyJurnal

We report one case of posterior fossa intracranial haemorrhage in a full-term Malay baby boy following vacuum assisted delivery. The patient, a term baby boy was delivered by a vacuum extraction and later developed signs of increased intracranial pressure 72 hours after birth. Computed tomography (CT) of the brain showed a posterior fossa intracranial haemorrhage with acute obstructive hydrocephalus. He was initially treated with isolated ventricular shunting which later caused an upward cerebellar herniation. An immediate suboccipital craniectomy for evacuation of cerebellar haematoma was performed which resulted in a gradual recovery.
