| Abstract |
Caesarean delivery carries a risk of major intra-operative blood loss and its performance is often delayed by non-availability of blood and blood products. Unnecessary cross-matching and reservation of blood lead to apparent scarcity in centres with limited supply. This study set out to identify the risk factors for blood transfusion in women who underwent caesarean delivery at a tertiary obstetric unit with a view to ensuring efficient blood utilization. A prospective cohort analysis of 906 women who had caesarean deliveries at the Lagos State University Teaching Hospital, Nigeria between January and December, 2011. A comparison was made between 188 women who underwent blood transfusion and 718 who did not. Data were obtained on a daily basis by investigators from patients, clinical notes and referral letters using structured pre-tested data collecting form. Socio-demographic characteristics; antenatal, perioperative and intraoperative details; blood loss; transfusion; and puerperal observations were recorded. EPI-Info statistical software version 3.5.3 was used for multivariable analysis to determine independent risk factors for blood transfusion. Of the 2134 deliveries during the study period, 906 (42.5%) had caesarean deliveries and of which 188 (20.8%) were transfused. The modal unit of blood transfused was 3 pints (41.3%). The most common indication for caesarean section was cephalo-pelvic disproportion (25.7%).The independent risk factors for blood transfusion at caesarean section were second stage Caesarean Section (aOR = 76.14, 95% CI = 1.25-4622.06, p = 0.04), placenta previa (aOR = 32.57, 95% CI = 2.22-476.26, p = 0.01), placental abruption (aOR = 25.35, 95% CI = 3.06-211.02, p < 0.001), pre-operative anaemia (aOR = 12.15, 95% = CI 4.02-36.71, p < 0.001), prolonged operation time (aOR = 10.72 95% CI = 1.37-36.02, p < 0.001), co-morbidities like previous uterine scar (aOR = 7.02, 95% CI = 1.37-36.02, p = 0.02) and hypertensive disorders in pregnancy (aOR = 5.19, 95% CI = 1.84-14.68, p < 0.001). Obesity reduced the risk for blood transfusion (aOR = 0.24, 95% CI = 0.09-0.61, p = 0.0024). The overall risk of blood transfusion in cesarean delivery is high. Paturients with the second stage Caesarean section, placenta previa, abruptio placentae and preoperative maternal anaemia have an increased risk of blood transfusion. Hence, adequate peri-operative preparations for blood transfusion are essential in these situations. Optimizing maternal hemoglobin concentration during antenatal period may reduce the incidence of caesarean-associated blood transfusion. |

This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 10 January 2018.
All research outputs
#5,807,468
of 23,015,156 outputs
Outputs from BMC Pregnancy and Childbirth
#1,502
of 4,238 outputs
Outputs of similar age
#115,994
of 443,280 outputs
Outputs of similar age from BMC Pregnancy and Childbirth
#50
of 92 outputs
Altmetric has tracked 23,015,156 research outputs across all sources so far. This one has received more attention than most of these and is in the 74th percentile.
So far Altmetric has tracked 4,238 research outputs from this source. They typically receive more attention than average, with a mean Attention Score of 8.8. This one has gotten more attention than average, scoring higher than 61% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 443,280 tracked outputs that were published within six weeks on either side of this one in any source. This one has gotten more attention than average, scoring higher than 73% of its contemporaries.
We're also able to compare this research output to 92 others from the same source and published within six weeks on either side of this one. This one is in the 34th percentile – i.e., 34% of its contemporaries scored the same or lower than it.
