Background: The Cervical Ripening Balloon (CRB) is a novel
mechanical method for induction of labour (IOL), reducing
the risks of hyperstimulation associated with
pharmacological methods. However, there remains a paucity
of literature on its application in high risk mothers, who have
an elevated risk of uterine rupture, namely those with
previous scars and grandmultiparity.
Methodology: A retrospective study on IOL using the CRB in
women with previous caesarean section or grandmultiparity
between January 2014 and March 2015. All cases were
identified from the Sarawak General Hospital CRB request
registry. Individual admission notes were traced and data
extracted using a standardised proforma.
Results: The overall success rate of vaginal delivery after
IOL was 50%, although this increases to about two-thirds
when sub analysis was performed in women with previous
tested scars and the unscarred, grandmultiparous woman.
There was a significant change in Bishop score prior to
insertion and after removal of the CRB. The Bishop score
increased by a score of 3.2 (95% CI 2.8-3.6), which was
statistically significant (p<0.01) and occurred across both
subgroups, not limited to the grandmultipara. There were no
cases of hyperstimulation but one case of intrapartum fever
and scar dehiscence each (1.4%). Notably, there were two
cases of change in lie/presentation after CRB insertion.
Conclusion: CRB adds to the obstetricians’ armamentarium
and appears to provide a reasonable alternative for the IOL
in women at high risk of uterine rupture. Rates of
hyperstimulation, maternal infection and scar dehiscence
are low and hence appeals to the user.

Background: The contemporary obstetrician is increasingly
put to the test by rising numbers of pregnancies with
morbidly adherent placenta. This study illustrates our
experience with prophylactic bilateral internal iliac artery
occlusion as part of its management.
Methods: Between January 2011 to January 2014, 13
consecutive patients received the intervention prior to
scheduled caesarean delivery for placenta accreta. All cases
were diagnosed by ultrasonography, color Doppler imaging
and supplemented with MRI where necessary. The Wanda
balloonTM catheter (Boston Scientific, Natick, MA, U.S.A)
were placed in the proximal segment of the internal iliac
arteries preceding surgery. This was followed by a midline
laparotomy and classical caesarean section, avoiding the
placenta. Both internal iliac balloons were inflated just
before the delivery of fetus and deflated once haemostasis
was secured. Primary outcomes measured were
perioperative blood loss, blood transfusion requirement and
the need for ICU admission.
Results: The mean and median intraoperative blood loss
were 1076mls±707 and 800mls (300-2500) respectively while
mean perioperative blood loss was 1261mls±946. Just over
half of the patients in our series required blood and/or blood
products transfusion. Two patients (15.4%) required ICU
admission.
Conclusion: Our study suggests that preoperative
prophylactic balloon occlusion of bilateral internal iliac
arteries reduces both blood loss and transfusion
requirement in patients with placenta accreta, scheduled to
undergo elective caesarean hysterectomy. It is an adjunct to
be considered in the management of a modern day obstetric
problem, although the authors are cautious about
generalizing its benefit without larger, randomized trials.

Background: In the course of managing preterm labour,
increasing trends of total white cell count raises concern for
the obstetrician, suggesting a possible underlying
infectious aetiology. Although mild leukocytosis is expected
in pregnancy, the patterns of increment after corticosteroid
administration are not well described beyond animal models
and in a small number of human studies.
Methods: Seventy-three consecutive patients who required
antenatal corticosteroids for either preterm labour or
prelabour caesarean section were recruited and given a
standard course of 12mg dexamethasone phosphate, twelve
hours apart. Venous blood samples were taken before
administration, at six hours and 36 hours after the first dose
of dexamethasone.
Results: The total white count trend was 10.31±2.62 at
baseline, 11.44±3.05 at six hours and 12.20±3.49 at 36 hours.
Neutrophil-lymphocyte ratio was 3.60±1.31, 8.73±3.63 and
3.24±1.49 respectively, reflecting relative neutrophilia and
lymphopenia which normalised by 36 hours.
Conclusion: In contrast to previous studies, we found only a
slight increment in total white cell count of about 10%. The
marginal changes described in our study would not
normally raise any clinical concern, although vigilance
should be exercised if higher levels were observed.

4.Septic miscarriage with toxic shock syndrome and disseminated intravascular coagulation (DIC): The role of surgery, recombinant activated factor VII and intravenous immunoglobulin (IVIG)

Severe sepsis with multi-organ failure is associated with ahigh mortality rate. This case report highlights thechallenges and modalities available in the management of alady with refractory shock and disseminated intravascularcoagulation (DIC) due to toxic shock syndrome (TSS) fromgenital tract sepsis. Early surgical intervention to removethe source of infection, the use of recombinant activatedfactor VII to treat intractable disseminated intravascularcoagulation and intravenous immunoglobulin to neutralisethe circulating exotoxins, have been employed and shown todrastically improve outcomes.
