Umbilical vein oxytocin administration in the management of the third stage of labor

The present study included a total of 90 normal pregnant females at labor selected from the obstetric department of Kasr Aini Hospital. These patients were divided into 3 groups, 30 patients for each group. In group "A", each patient received 20 units oxytocin diluted 20 ml of normal saline into the umbilical vein after cord clamping. Group "B" received intramuscular injection of 20 units oxytocin after cord clamping. Group "C" received injection of 20 ml of normal saline into the umbilical vein after cord clamping plus 20 units of oxytocin intramuscularly. All the patients in the 3 groups received another 20 post-partum by the intravenous drip method. The study revealed that the injection of oxytocin into the umbilical vein has a significant effect on shortening the duration of the third stage of labor and reducing the blood loss during it, although umbilical vein injection of saline shortens the third stage but added oxytocin has a more significant effect. However, saline injection alone does not affect the blood loss while umbilical vein injection of oxytocin significantly reduces the blood loss during the third stage. The use of the intraumbilical vein injection of oxytocin, immediately after clamping the cord, can be recommended as an effective and safe step in the management of the third stage of labor

Charge transfer complexes of some diazines with p-benzoquinone derivatives

Charge transfer complexes formed between chloranilic acid [I], dichlorodicyano-p-benzoquinone [II] and chloranil as electron acceptor and pyrimidine. Pyrazine and their 2-amino derivatives as electron donors are prepared. The structure of the isolated solid complexes has been investigated using elemental analysis and IR-spectroscopy. The results reveal the formation of CT complexes of the salt type with [I] as acceptor and molecular complexes with II and III as acceptors. The study indicates the feasibility of the protonation of the heterocyclic nitrogen under the reaction in absence of the aliphatic amino group as in cases of the first two donors. The study indicates that diazines are mainly pi-donors
