Background (Research Question, Available Data from the literature, Current strategy for dealing with the problem, Rationale of the research that paves the way to the aim(s) of the work). (200-250 words max.)~In the advanced stages of cirrhosis, there is pronounced arterial vasodilatation that further worsens by therapeutic paracentesis which plays a major role in causing circulatory dysfunction (El-Motey et al. 2013). Paracentesis-induced circulatory dysfunction (PICD) in cirrhotics with tense ascites develops in the majority of patients not receiving plasma volume expansion (Hamdy et al.,2014). Paracentesis induced circulatory dysfunction (PICD) will induce pronounced arterial vasodilatation in cirrhotic patients with tense ascites which can be prevented by the infusion of albumin, (Arora et al.,2020). albumin infusion is highly effective in preventing this disorder. However, albumin substitution is costly and holds the theoretical risk of infectious complications and allergic reactions (Arora et al.,2020). Various vasoconstrictors have also been used to prevent PICD such as terlipressin and noradrenaline. However, terlipressin is expensive and not available in some countries, and the use of noradrenaline requires intravenous (IV) infusion and intense monitoring (Singh et al .,2006), but there are few studies about the usage of crystalloids (Arora et al.,2020).
2.2 Aim(s) of the Research (50 words max):~To Compare between crystalloid and colloid I.V fluid therapy in the prevention of paracentesis induced circulatory dysfunction (PICD) and renal dysfunction in patients with decompensated liver cirrhosis in Egypt.~To evaluate systemic vascular resistance in cirrhotic patients with tense ascites before and after therapeutic paracentesis.
