Objective To compare the outcome of uterine exteriorisation repair with in situ in caesarean section. Methods A randomized controlled trial with 220 cases were recruited. Woman with term singleton pregnancy underwent caesarean section and without severe complication were randomly allocated to the two groups (112 cases in exteriorisation group and 108 cases in situ group). Women in treatment group received exteriorisation when the uterus was sutured, While others had the uterus repaired in situ as control. Main outcome measures included perioperative haemodynamic parameters, loss of blood, changes in haemoglobin concentration, duration of operation, postoperative pain score and febrile days, gastrointestinal discomforts and function recovery as well as postoperative maternal morbidity.Data were analyzed by SPSS 11.0. Results Haemoglobin concentration dropped in both groups after caesarean section, and the drops in control group was significantly higher than that of treatment group (t=-2.902, P=0.004). In both groups, pulse before operation was markedly higher than when suturing the uterus and postoperation (Plt;0.05), but no difference was observed between the two groups. Systolic blood pressure of treatment group was lower than that of control group before operation, when suturing the uterus and after operation (F=5.246, P=0.022), but there was no difference among these 3 time points within the group. Onset of flatus was earlier in control group than in treatment group (t=5.567, P=0.000). No difference was identified between the two groups when receiving the different suturing methods. No severe maternal morbidity was observed.Conclusions Uterine exteriorisation and in situ repair have similar effects on intra- and postoperative outcomes. In routine process.
ObjectiveTo compare postoperative patient-controlled epidural analgesia (PCEA) and intravenous patient-controlled analgesia (PCIA) on maternal low back pain after caesarean section. MethodsSixty cases of American Society of Anesthesiology gradeⅠ-Ⅱ single-birth full-term elective caesarean delivery primiparae chosen between July to September 2012 were divided into 3 groups randomly, 20 in each group. Group A accepted sufentanil 1 μg/mL and ropivacaine 1 mg/mL PCEA; group B had sufentanil 1.5 μg/mL PCEA; group C was given sufentanil 1.5 μg/mL and ondansetron 0.16 mg/mL PCIA. Background dose was 2 mL/h, patient-controlled analgesia dose was 2 mL, and locking time was 20 min. Visual analogue pain score was used to assess the effect of postoperative analgesia, and we recorded analgesia pump usage, adverse reactions, and at the same time investigated the onset of maternal low back pain. ResultsNo obvious postoperative pain was found, and the analgesic effect was good in all the three groups, and the differences were not statistically significant (P>0.05). All three groups of women had a certain proportion of low back pain, and the differences were not statistically significant (P>0.05). After operation, group A had 5 cases of leg numbness, group B had 1, and group C had none. Leg numbness occurred significantly more in group A than in group B and C (P<0.05). Group B had one case of nausea and vomiting, while none occurred in group A and C (P>0.05). ConclusionWith the same effect of postoperative analgesia, compared with PCIA, PCEA does not increase postoperative low back pain incidence after caesarean section.
