Sow cannot urinate after farrowing? Traditional Chinese medicine calls it postpartum uroschesis, and here are treatment prescriptions
Traditional Chinese medicine calls it postpartum uroschesis. As pig production becomes increasingly intensive, pregnant sows have less and less space to move around, which leads to an increase in postpartum urinary retention, and the losses caused to the pig farming industry are also rising year by year.
1. Causes of the disease
(1) In late pregnancy, abdominal pressure increases, the pressure on the bladder rises, and the excitation threshold of the urination center increases; after farrowing, abdominal pressure drops, and the bladder is in a semi-paralyzed state.
(2) The farrowing process is too long, and the bladder is paralyzed by repeated squeezing from the fetuses.
(3) The fetus is too large, or the urethra is injured during assisted farrowing, and the mucosa becomes edematous.
2. Clinical symptoms
1~2 days after farrowing, no urination is seen; body temperature is generally normal; the sow arches her back and strains, with no urine passing at all or only a slight dribble. After 3~4 days, the abdomen becomes distended, the sow rises and lies down very carefully, and shows thoracic breathing. In the later stage, body temperature rises, appetite is completely lost, the sow is depressed, and the abdomen is painful and restless. 3.Treatment
Integrated traditional Chinese and Western medicine is mostly usedtreatment, with Western medicine reducing inflammation and traditional Chinese medicine opening the orifices and promoting diuresis.
(1) Place a wooden board under the affected pig's lower abdomen, and two people gently lift the abdomen upward (be careful to prevent bladder rupture; do not use this in the middle and late stages of the disease), increasing abdominal pressure and increasing the stimulation of the distended bladder on the urination center, so that excitation is produced and urination occurs.
(2) When there is painful restlessness, use a urinary catheter promptly to drain urine.
(3) Reduce inflammation. Inject broad-spectrum antibiotics intramuscularly to prevent inflammation of the bladder and urethra.
(4) Traditional Chinese medicine to open the orifices and promote water metabolism. According to traditional Chinese medicine theory, uroschesis is divided into excess and deficiency types.
The excess type is mostly caused by metabolic disorders in late pregnancy, internal generation of damp-heat, or external contraction of damp-heat warm pathogens; damp-heat accumulates in the lower jiao, bladder qi transformation is unfavorable, and urinary retention is caused. Affected animals mostly show a red tongue, yellow or greasy coating, yellow and concentrated urine, and a dry or insufficiently moist nasal-labial mirror. The treatment should use Bazheng San (mutong 20 g, qumai 15 g, cheqianzi 10 g, bianxu 10 g, huashi 15 g, zhizi 10 g, dahuang 10 g). If dampness is predominant, add yimi 15 g, huoxiang 10 g, huangqin 5 g, etc.; if heat is predominant, add erhua and lianqiao 10 g each.
The deficiency type is mostly dual deficiency of the spleen and kidney. The kidney governs the two yin orifices; kidney deficiency prevents qi transformation and water movement, opening and closing are unregulated, and urinary retention occurs. The syndrome manifests as a bland taste in the mouth, white coating, clear and not turbid urine, body temperature toward the lower limit, cold ears and nose, and depression. The treatment should reinforce and supplement the spleen and kidney, open the orifices, and promote water metabolism; the prescription uses Wuling San with zhizi and dahuang removed, plus guizhi 10 g, huangqi 5 g, dangshen 10 g, and sangjisheng 5 g.
(5) Duringtreatment, do not give large-volume fluid therapy or use diuretics such as furosemide, to prevent worsening of the condition.
