Abstract. The aim of this study is to assess the decision to delivery interval in
our obstetric unit in comparison to current recommendations. A retrospective
study included an analysis of consecutive non-elective caesarean sections
performed at King Abdulaziz University Hospital, Jeddah, Saudi Arabia
from January to June 2008. The decision to delivery interval was compared
between emergency and non urgent caesarean sections. During the study
period, 213 non-elective caesarean sections were performed, 164 were
classified as non urgent caesarean (Group 1) and 49 as emergency caesarean
(Group 2). The median and inter-quartile ranges in the decision to delivery
interval were 62.5 min (45-80) and 41 min (27-68) in Group 1 and 2,
respectively (p < 0.001). In the Group 1, 10.3% delivered within 30 min
compared to 30.6 % in the Group 2 (p < 0.05). No correlation was found
between the decision to delivery interval and the Apgar score at 1 minor 5
min in both groups. It’s believed that all centers should set a standard of
decision to delivery interval of 30 min. that needs to be achieved in order to
reduce maternal anxiety and physician's liability.
Keywords: Caesarean sections, Decision to delivery interval.
Introduction
The American College of Obstetricians and Gynecologists (ACOG)
recommend that the decision to delivery interval (DDI) for emergency
K.H. Sait48
caesarean section (C/S) should not exceed 30 min[1]
. However, this
recommendation does not appear to be sustained by evidence based
data[2-6]
, and is probably drawn from medico-legal grounds. In practice,
the DDI is mainly influenced by the facilities and staff availability[7]
.
Primarily, our study was performed to assess how close our obstetric
unit was to achieving the target of 30 min in emergency caesarean
sections. Secondly, the requisite to evaluate the DDI in non-urgent
caesarean sections performed during labor. Finally, the necessity to
appraise the influence of DDI on fetal outcome reflected by 1 and 5 min
Apgar score.
Materials and Methods
This retrospective study included an analysis of consecutive non-
elective caesarean sections performed at King Abdulaziz University
Hospital in Jeddah, Saudi Arabia from January to June 2008. The
delivery ward is fully equipped with maternal and fetal monitoring
facilities. Two operating theaters (emergency operating room) are located
within the delivery ward and are few meters from the nurses’ station. All
non elective caesarean sections are performed in the emergency operating
room within the delivery ward.
An emergency C/S was defined as one, which required prompt
delivery to reduce the risk to the pregnant women or their infants. The
pre-operative diagnoses included fetal distress, substantially heavy
vaginal bleeding in suspected placental abruption, heavily bleeding
placenta previa, or suspected ruptured uterus and a prolapsed umbilical
cord. A non-urgent C/S was defined as one performed during labor for
other indication (Table 1). The DDI was defined as the time between the
decision to perform the C/S and the delivery of the infant. The operation
was performed either under general or spinal anesthesia, depending on
the urgency.
Statistical Analysis
Statistical analysis was performed by “student's” t-test, Pearson's chi-
square (X²) test and Spearman's correlation analysis (r). As indicated, the
distribution of difference in time of delivery was tested for normality
using the Kolmogorov-Smirnov (K-S) test and was found to be Non-

parametric. Mann-Whitney u-test was used for Non-parametric data
significance set at p < 0.05.

Results
During the study period, 213 non-elective caesarean sections were
performed, 164 were classified as non urgent caesarean (Group 1) and 49
as emergency caesarean (Group 2).

The median and inter-quartile range (IQR) of DDI were 62.5 min
(45-80) and 41 min (27-68) in the Group 1 and 2, respectively (p <
0.001). In the Group 1, 10.3% delivered within 30 mins compared to 30.6
% in the group 2 (p < 0.05). The mean DDI ± SD was 73.18 ± 75 and 50
± 31.86 in Group 1 and 2, respectively (Table 3). No correlation was
found between the DDI and Apgar score at 1 min or 5 min in both
groups. During the study period, 23 patients required C/S that had come
to the delivery room in labour with history of previous one caesarean
section, four of them were in Group 2 with median DDI 41 min (IQR =
37-82) and mean ± SD 53.5 ± 28.44.

Discussion
In our study, the goal of 30 min DDI was achieved in 30.6% of
emergency caesarean sections with a mean of 50 min. In comparison, the
previously reported range was between 44 and 71%[3-6,8-10]
. The factors
that may influence the DDI in our institute included, the type of
The Decision to Delivery Interval in Emergency and Non-Urgent Cesarean Sections at KAUH 51
anesthesia and the experience of the staff. Regional anesthesia was
associated with longer intervals than general anesthesia[4]
. Furthermore, it
was previously shown that the DDI may be significantly shortened with
improvement in experience of the staff[10]
. Although the rates of general
and spinal anesthesia were statistically different (p < 0.05) in emergency
and non-urgent caesareans in our study, it was found that this difference
did not influence the DDI in emergency caesarean section group. The
question is whether different degree of urgency in the response of the
staff will have a positive effect on perinatal outcome. Intuitively, the
longer is the decision to delivery interval, the poorer the perinatal
outcome should be. No correlation was found between Apgar score and
the decision to delivery interval. Similar results were obtained by other
investigators[2,3,6,11]
. Finally, the question is whether a more lenient
standard should be recommended for the decision to delivery interval.
Helmy et al.[10]
argued that since the 40 min DDI could be achieved in
90% of emergency caesareans, the 40 min standard is more realistic. A
close to 70% achievement was made with a 60 min standard in our center
in emergency caesarean section. It’s believed, that once a decision to
perform a caesarean was made, every effort should be made in order to
accomplish it as soon as possible. Even if it is not associated with better
perinatal outcome, it may reduce maternal anxiety and physician's
liability. Setting the standard at 60 min may result in lowering of the
degree of urgency by the staff as evident from the DDI in non-urgent
caesarean. Therefore, the arbitrary 30 min DDI in emergency caesareans
still seems valid, especially in setting of trial of labour after one
caesarean section. Although this was not achieved in our center, great
benefit was accomplished from our review by promoting increased
awareness of this delay and educate our staff in order to improve the
quality of work.

Sait, MBChB, FRCSC Department of Obstetrics & Gynecology, Faculty of Medicine King Abdulaziz University Hospital Jeddah, Saudi Arabia khalidsait@yahoo.com Abstract. The aim of this study is to assess the decision to delivery interval in our obstetric unit in comparison to current recommendations. A retrospective study included an analysis of consecutive non-elective caesarean sections performed at King Abdulaziz University Hospital, Jeddah, Saudi Arabia from January to June 2008. The decision to delivery interval was compared between emergency and non urgent caesarean sections. During the study period, 213 non-elective caesarean sections were performed, 164 were classified as non urgent caesarean (Group 1) and 49 as emergency caesarean (Group 2). The median and inter-quartile ranges in the decision to delivery interval were 62.5 min (45-80) and 41 min (27-68) in Group 1 and 2, respectively (p < 0.001). In the Group 1, 10.3% delivered within 30 min compared to 30.6 % in the Group 2 (p < 0.05). No correlation was found between the decision to delivery interval and the Apgar score at 1 minor 5 min in both groups. It’s believed that all centers should set a standard of decision to delivery interval of 30 min. that needs to be achieved in order to reduce maternal anxiety and physician's liability. Keywords: Caesarean sections, Decision to delivery interval. Introduction The American College of Obstetricians and Gynecologists (ACOG) recommend that the decision to delivery interval (DDI) for emergency
  • 2. K.H. Sait48 caesarean section (C/S) should not exceed 30 min[1] . However, this recommendation does not appear to be sustained by evidence based data[2-6] , and is probably drawn from medico-legal grounds. In practice, the DDI is mainly influenced by the facilities and staff availability[7] . Primarily, our study was performed to assess how close our obstetric unit was to achieving the target of 30 min in emergency caesarean sections. Secondly, the requisite to evaluate the DDI in non-urgent caesarean sections performed during labor. Finally, the necessity to appraise the influence of DDI on fetal outcome reflected by 1 and 5 min Apgar score. Materials and Methods This retrospective study included an analysis of consecutive non- elective caesarean sections performed at King Abdulaziz University Hospital in Jeddah, Saudi Arabia from January to June 2008. The delivery ward is fully equipped with maternal and fetal monitoring facilities. Two operating theaters (emergency operating room) are located within the delivery ward and are few meters from the nurses’ station. All non elective caesarean sections are performed in the emergency operating room within the delivery ward. An emergency C/S was defined as one, which required prompt delivery to reduce the risk to the pregnant women or their infants. The pre-operative diagnoses included fetal distress, substantially heavy vaginal bleeding in suspected placental abruption, heavily bleeding placenta previa, or suspected ruptured uterus and a prolapsed umbilical cord. A non-urgent C/S was defined as one performed during labor for other indication (Table 1). The DDI was defined as the time between the decision to perform the C/S and the delivery of the infant. The operation was performed either under general or spinal anesthesia, depending on the urgency. Statistical Analysis Statistical analysis was performed by “student's” t-test, Pearson's chi- square (X²) test and Spearman's correlation analysis (r). As indicated, the distribution of difference in time of delivery was tested for normality using the Kolmogorov-Smirnov (K-S) test and was found to be Non-

In the Group 1, 10.3% delivered within 30 mins compared to 30.6 % in the group 2 (p < 0.05). The mean DDI ± SD was 73.18 ± 75 and 50 ± 31.86 in Group 1 and 2, respectively (Table 3). No correlation was found between the DDI and Apgar score at 1 min or 5 min in both groups. During the study period, 23 patients required C/S that had come to the delivery room in labour with history of previous one caesarean section, four of them were in Group 2 with median DDI 41 min (IQR = 37-82) and mean ± SD 53.5 ± 28.44.

Discussion In our study, the goal of 30 min DDI was achieved in 30.6% of emergency caesarean sections with a mean of 50 min. In comparison, the previously reported range was between 44 and 71%[3-6,8-10] . The factors that may influence the DDI in our institute included, the type of
  • 5. The Decision to Delivery Interval in Emergency and Non-Urgent Cesarean Sections at KAUH 51 anesthesia and the experience of the staff. Regional anesthesia was associated with longer intervals than general anesthesia[4] . Furthermore, it was previously shown that the DDI may be significantly shortened with improvement in experience of the staff[10] . Although the rates of general and spinal anesthesia were statistically different (p < 0.05) in emergency and non-urgent caesareans in our study, it was found that this difference did not influence the DDI in emergency caesarean section group. The question is whether different degree of urgency in the response of the staff will have a positive effect on perinatal outcome. Intuitively, the longer is the decision to delivery interval, the poorer the perinatal outcome should be. No correlation was found between Apgar score and the decision to delivery interval. Similar results were obtained by other investigators[2,3,6,11] . Finally, the question is whether a more lenient standard should be recommended for the decision to delivery interval. Helmy et al.[10] argued that since the 40 min DDI could be achieved in 90% of emergency caesareans, the 40 min standard is more realistic. A close to 70% achievement was made with a 60 min standard in our center in emergency caesarean section. It’s believed, that once a decision to perform a caesarean was made, every effort should be made in order to accomplish it as soon as possible. Even if it is not associated with better perinatal outcome, it may reduce maternal anxiety and physician's liability. Setting the standard at 60 min may result in lowering of the degree of urgency by the staff as evident from the DDI in non-urgent caesarean. Therefore, the arbitrary 30 min DDI in emergency caesareans still seems valid, especially in setting of trial of labour after one caesarean section. Although this was not achieved in our center, great benefit was accomplished from our review by promoting increased awareness of this delay and educate our staff in order to improve the quality of work.
