BACKGROUND: Newborn infants have the ability to experience pain. Newborns treated in neonatal intensive care units are exposed to numerous painful procedures. Healthy newborns are exposed to pain if the birth process consists of assisted vaginal birth by vacuum extraction or by forceps and during blood sampling for newborn screening tests. OBJECTIVES: Primary objectiveTo determine the efficacy and safety of paracetamol for the prevention or treatment of procedural/postoperative pain or pain associated with clinical conditions in neonates...

BACKGROUND: Occiput posterior position is the most common malpresentation in labour, contributes to about 18% of emergency caesarean sections and is associated with a high risk of assisted delivery. Caesarean section is now a major contributing factor to maternal mortality and morbidity following childbirth in developed countries. Obstetric intervention by forceps and ventouse delivery is associated with complications to the maternal genital tract and to the neonate, respectively. There is level 2 evidence that prophylactic manual rotation reduces the caesarean section rate and assisted vaginal delivery...

The neonatal intensive care unit (NICU) manager calls you about a baby delivered last night now with brain trauma. She understands that it was a difficult delivery with a vacuum. There were "multiple pop-offs" and, after the baby was delivered, the NICU resuscitation team was called. The Apgar scores were 3 and 5. They are requesting risk management to lead a debriefing today. What to ask? How many pop-offs are allowed? What was the interaction between the nurses and physician? Why wasn't the resuscitation team in attendance before the delivery? Was the vacuum placed properly? How many pulls? How long was the vacuum in place? What should be documented, and was the documentation adequate? All of these are appropriate questions for an adequate analysis of an adverse outcome resulting from a vacuum-assisted vaginal delivery (VAVD)...

This paper presents 35 years of history of operative vaginal delivery at the Port Moresby General Hospital (PMGH). From the early 1970s when Dr. G.C. Bird was appointed as Head of Obstetrics at PMGH, vacuum extraction has been the preferred method of assisted vaginal delivery. In the early 1970s, Dr Bird began to experiment with more effective configurations of the then standard metal Malmstrom vacuum extraction cup: the Bird anterior cup was introduced in 1973 and the posterior cup in 1974. These modifications to the vacuum extractor cup allowed for more effective placement of the cup on the flexion point on the fetal head thereby facilitating more successful vacuum-assisted delivery...

BACKGROUND: Intrapartum complications are responsible for approximately half of all maternal deaths, and two million stillbirth and neonatal deaths per year. Prolonged second stage of labour is associated with potentially fatal maternal complications such as haemorrhage and infection and it is a major cause of stillbirth and newborn morbidity and mortality. Currently, the three main options for managing prolonged second stage of labour are forceps, vacuum extractor and caesarean section...

Perinatal morbidity and mortality rates for vasa previa are high when it is not diagnosed antenatally. In this report, a case of vasa previa in a twin pregnancy was diagnosed postnatally, which leads to complications with the first twin. Serial ultrasound during pregnancy did not diagnose a bilobed placenta, a velamentous insertion of the umbilical cord or vasa previa. At 37 weeks, vaginal bleeding was detected in the expulsive stage and vaginal-assisted delivery of both fetuses was undertaken. The first fetus was born pale and anaemic, and required a blood transfusion and therapeutic hypothermia...

OBJECTIVE: To compare perinatal outcomes between forceps- and vacuum-assisted deliveries. Our hypothesis was that the force vectors achieved in forceps delivery will lead to fewer shoulder dystocias, but greater perineal lacerations. METHODS: This was a retrospective cohort study of 4,120 term, cephalic, singleton, nonrotational operative vaginal deliveries at a single institution. Outcomes examined included rates of neonatal trauma, shoulder dystocia, and perineal lacerations...

OBJECTIVE: The objective of this retrospective study was to test the hypothesis that vacuum extraction of neonates with a birth weight < or = 2000 gm is associated with an increased risk of periventricular-intraventricular hemorrhage (PV-IVH). STUDY DESIGN: One hundred sixty-eight neonates weighing < or = 2000 gm were entered into this case control study. Fifty-six neonates delivered by silicone-rubber vacuum comprised the study group. For every infant born by vacuum-assisted delivery, two spontaneously delivered neonates served as controls (n = 112) and were matched for best obstetric gestational age (within 1 week), delivery date within 1 year, and birth weight < or = 2000 gm...
