Risk of rupture in LSCS is (LQ)
a. Risk of rupture in LSCS is 0.2 -1.5%. The risk of rupture in classical caesarean is 4-9%.The risk of rupture when a trial of labour is given in Previous LSCS is 1 in 1000.
b. The low rate of rupture of lower segment is because of better healing that occurs as the lower segment is quiescent in puerperium and allows the scar to heal well.
c. The two edges in the lower sement are of same calibre and when approximated heal well without hemorrhages that weaken the scar.
