Using Ringer's Lactate to Prevent Low Blood Pressure After Anesthesia

Dose Responsive Study of Ringer's Lactate Solution in Prevention of Post-induction Hypotension Predicted by Inferior Vena Cava Collapsibility Index in Patients Receiving General Anesthesia

Not applicable Interventional Tata Main Hospital · NCT05924230

This study is testing whether giving different amounts of Ringer's Lactate solution before anesthesia can help prevent low blood pressure in patients during surgery.

What this trial studies

This study evaluates how different doses of Ringer's Lactate solution can prevent low blood pressure following the induction of general anesthesia. Patients will undergo an ultrasound to measure the diameter of the inferior vena cava to predict their risk of post-induction hypotension. Based on their body weight and assigned group, patients will receive either 10ml/kg or 15ml/kg of Ringer's Lactate before anesthesia induction. Continuous monitoring of vital signs will occur throughout the procedure to assess the effectiveness of the intervention.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 years and older undergoing elective surgery with ASA physical status classification I or II.

Not a fit: Patients under 18 or over 65 years, those with ASA classification III or IV, or those undergoing emergency surgery may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly reduce the incidence of post-induction hypotension, improving patient safety during surgeries.

How similar studies have performed: While the specific approach of using Ringer's Lactate in this context may be novel, similar studies have shown that fluid preloading can help mitigate hypotension during anesthesia.
