A Comparison between the effects of crystalloids and colloids on lung ultrasound score in preeclamptic patients: A Randomized double blinded controlled Trial

Background: Ultrasound is now widely used in many medical specialties, being safe tool for both the parturient and the baby. There is no epidemiological evidence to support the choice of colloidal solutions over crystalloids and it is not clear that colloidal solutions would be more effective and less likely to cause harm than crystalloids in preeclamptic patients Aim: Comparison between the effects of crystalloids and colloids on the lung ultrasound score in preeclampsic patients during cesarean delivery. Patients and methods: Forty-four pre-eclampsia patients were enrolled in the study at Kasr Al-Ainy Hospital, Department of Obstetrics and Gynecology, after taking a written consent to participate. Medical history and vital signs were recorded, and 500 milliliters of crystalloid or colloid according to the blind randomization was given to both groups to compare fluids effect on lung ultrasound score, thoracic fluid content and cardiac output were measured at the beginning and after thirty minutes by ultrasound and electrocardiometry. Results: LUS shows that’s there no effective difference between the 2 groups of fluids in affecting the lung congestion degree measured by the lung ultrasound score. Thoracic fluid content comparison between the two groups showed non- statistical difference between the groups. The measurement of the TFC after 30 minutes showing no effective difference between the 2 groups in increasing congestion and the lung fluid content measured by icon cardiometry. Both fluids could maintain proper perfusing COP that maintained blood pressure and perfusion without congestion Conclusion: We recommend conducting more studies on bigger number of patient and may be with applying bigger intravenous volume as we started a step in identifying the proper intravenous fluid in preeclampsia cases
