ObjectiveTo observe the clinical analgesic effects of rectus sheath block and its effect on postpartum depression after cesarean section.

MethodsSixty puerperas with ASA level Ⅰ to Ⅲ, treated with cesarean section were randomly divided into the control group(group N) and rectus sheath block group(group R)(30 cases in each group).The combined lumbar and epidural anesthesia in two groups were performed.After the operation, the bilateral rectus sheath block guided by ultrasound in group R was performed, while the rectus sheath block was not performed in group N.Two groups were treated with intravenous controlled analgesia pump after obstetric operation.The incision pain(resting and coughing), uterine contractile pain, postpartum depression and adverse reactions were observed after 6(T₁), 12(T₂), 24(T₃) and 48(T₄) of operation.

ResultsAt different time points after surgery, the NRS scores of incision pain at rest and coughing in group R were significantly lower those in group N(P < 0.01).The NRS score of uterine contractile pain in group R was lower than that in group N(P < 0.01).The incidence rates of adverse reactions and postpartum depression in group R were lower than those in group N(P < 0.05 to P < 0.01).

ConclusionsThe analgesia effects and maternal satisfaction after cesarean section in bilateral rectus sheath block combined with intravenous analgesia pump is better than that in simple intravenous analgesia pump, and which can reduce the incidence rate of postpartum depression within 48 h after surgery.
