A survey of interventional radiology for the management of obstetric haemorrhage in the United Kingdom.
Massive haemorrhage remains a leading cause of maternal death worldwide. Interventional radiology can be used to prevent or treat life-threatening haemorrhage, but evidence for its efficacy is limited to case series predominantly from large tertiary centres. The current availability of interventional radiology for management of obstetric haemorrhage in the UK is unknown. ⋯ Interventional radiology to assist in the management of obstetric haemorrhage is not uniformly available in the UK and experience remains limited. Access to this resource is subject to striking local variability and influenced by the size and nature of the hospital supporting the delivery unit.

Case ReportsThe use of fibrinogen concentrate to correct hypofibrinogenaemia rapidly during obstetric haemorrhage.
Haemorrhage is a common complication of childbirth with 0.65% of deliveries associated with significant (>1500 mL) peripartum blood loss. Hypofibrinogenaemia secondary to dilutional and consumptive coagulopathies can be challenging to correct quickly with conventional blood and plasma therapy. Fibrinogen concentrate offers rapid restoration of fibrinogen levels with a small volume infusion and minimal preparation time. ⋯ Six cases of obstetric haemorrhage, associated with hypofibrinogenaemia, treated with fibrinogen concentrate in conjunction with platelets, fresh frozen plasma, packed red blood cells, uterotonics and obstetric intervention are described. In all cases, laboratory assessed coagulation was rapidly normalised and severe haemorrhage improved. These cases suggest that fibrinogen concentrate may be an effective addition to conventional treatments for obstetric haemorrhage associated with hypofibrinogenaemia.

Randomized Controlled Trial Comparative StudyA randomized controlled trial using patient-controlled epidural analgesia with 0.25% versus 0.0625% bupivacaine in nulliparous labor: effect on analgesia requirement and maternal satisfaction.
The effect of epidural local anesthetic concentration on analgesic action is still the subject of debate. This study compared the effect of a four-fold change in concentration of bupivacaine for epidural analgesia in labor. ⋯ Larger volumes of more dilute solutions may result in dose sparing and provide more effective labor analgesia. This study supports the continued trend towards dilute local anesthetic mixtures for labor epidural analgesia.

Randomized Controlled TrialA randomised study of magnesium sulphate as an adjuvant to intrathecal bupivacaine in patients with mild preeclampsia undergoing caesarean section.
Adequate analgesia following caesarean section decreases morbidity, hastens ambulation, improves patient outcome and facilitates care of the newborn. Intrathecal magnesium, an NMDA antagonist, has been shown to prolong analgesia without significant side effects in healthy parturients. We therefore studied the effect of adding intrathecal magnesium sulphate to bupivacaine-fentanyl spinal anaesthesia in patients with mild preeclampsia undergoing caesarean section. ⋯ In parturients with mild preeclampsia undergoing caesarean delivery, the addition of magnesium sulphate 50 mg to the intrathecal combination of bupivacaine and fentanyl prolongs the duration of analgesia and reduces postoperative analgesic requirements without additional side effects.

Case ReportsCardiac arrest due to uterine inversion during caesarean section.
We describe the case of a 20-year-old G3P0 woman who was delivered by caesarean section under general anaesthesia, complicated by uterine inversion secondary to undiagnosed placenta accreta and cardiac arrest requiring cardiopulmonary resuscitation. Uterine inversion is a known complication of placenta accreta and is a rare occurrence at caesarean section. Similar cases have been reported, though cardiac arrest is an uncommon feature. The possible causes and management are discussed.
