Prolonged Labour
Parturition lasting over twenty - four hours is defined as prolonged labour . It
is often due to weak contraction and forceless contraction of the womb , or
narrow pelvic fetal and malposition of fetus .
Etiology and Pathogenesis
a ) Deficiency of qi and blood : Weak constitution with insufficient qi ,
exhaustion through premature contraction , premature amenorrhea , and depletion
of blood due to hemorrhage , all lead to prolonged labor . In Understanding of
Childbirth , it says , Physical weakness and early exertion of force have
exhausted the mother before the baby is delivered and thus the baby gets
stuck . Dryness in the vagina also brings about difficult delivery .
b ) Qi stagnation and blood stasis : Fear or too much worry over the
forthcoming delivery retards qi and stagnates blood . Extreme leisure during
gestation leads to impaired flow of qi and blood . Affection of external cold
during delivery binders the circulation of qi and blood . All of them are
causative factors of prolonged labor . Just as Golden Mirror of Medicine says ,
Prolonged labor derives from various factors such as seeking comfort and
ease and too much sleep , both of which lead to retarded flow of qi ; or from
fright and worry over the oncoming labor . . . and obstruction of vagina by blood
stasis from an injured uterus .
Differentiation
a ) Deficiency of qi and blood : Main manifestations : Dull and paroxysmal labor
pains with mild weighing and distending sensation , or profuse hemorrhage in
light color , pale complexion , lassitude , palpitation , shortness of breath ,
pale tongue , weak pulse .
Analysis : Since both qi and blood are deficient and the puerperant is too
weak to have uterus contraction , there are mild abdominal pain , mild heavy and
distending sensation , and the delivery duration is prolonged . Qi deficiency
leads to profuse hemorrhage in light color , pale complexion , lassitude ,
palpitation , and shortness of breath . Pale tongue and weak pulse are signs of
deficiency of qi and blood .
b ) Qi stagnation and blood stasis : Main manifestations : Sharp pains in the
waist and abdomen , scanty hemorrhage in dark red color , prolonged delivery
course , dark bluish complexion , depressive mood , fullness in the chest and
epigastruim , frequent nausea , dark tongue , deep forceful pulse .
Analysis : The retarded circulation of qi and blood gives rise to the sharp
pain in the waist and abdomen and prolonged course of delivery . The stagnated
qi does not ascend as usual , bringing about the dark bluish complexion ,
fullness and distension in the chest and epigastrium , and frequent nausea . The
dark tongue , deep and forceful pulse indicate qi stagnation and blood stasis .
Treatment
a ) Deficiency of qi and blood : Method : Points are chiefly chosen from the
Foot - Yangming and Foot - Taiyang Meridians . Acupuncture is given with the
reinforcing method with moxibustion to tonify qi and blood , and quicken the
delivery .
Prescription : Zusanii ( S 36 ) , Sanyinjiao ( Sp 6 ) , Zhiyin ( B 67 ) .
Explanation : Zusanii ( S 36 ) and Sanyinjiao ( Sp 6 ) may generate qi and blood
and tonify the spleen and stomach , while Zhiyin ( B 67 ) is an effective and
empirical oxytocic point . The three points thus used together fulfill the set
purpose of tonifying qi and blood and quickening the delivery .
b ) Stagnation of qi and blood : Method : Points are chiefly chosen from the
Hand - Yangming and Foot - Taiying Meridians . Acupuncture is given with the
reducing method to regulate qi and blood , activate qi so as to quicken the
delivery .
Prescription : Hegu ( Li4 ) , Sanyinjiao ( Sp 6 ) , Zhiyin ( B 67 ) .
Explanation : Hegu ( LI 4 ) is the Yuan - ( Primary ) Point of the Hand - Yangming
Meridian and Sanyinjiao ( Sp 6 ) is an intersecting point of the three foot yin
meridians . The two paired together may regulate qi and blood , clear off stasis
and speed up the delivery . Zhiyin ( B 67 ) is an effective and empirical
oxytocic point .
Remarks
Acupuncture and moxibustion carry an oxytocic effect to the prolonged labour
due to weak uterine contraction . Measures other than acupuncture and moxibustion
should be taken in case of prolonged labor caused by uterine deformity or
contracted pelvis .
