- Brief Summary
Significant hypotension is the most common side effect of spinal anaesthesia . Preoperative volume status is one of the predictive variables for developing spinal induced hypotension. Caval aorta index is effective to assess fluid responsiveness and the aim of this study is to evaluate the caval aort a index guided volume optimization to prevent post spinal hypotension. Various parameters have been investigated recently to estimate the preoperative intravascular volume status. Assessing intravascular volume status is still a challenging matter. Sonographic determination of caval aorta index was introduced into clinical practice for assessment of intravascular volume in many studies and reported to be reliable, noninvasive, and easy techniques for evaluating volume status. Thus, identifying a good, easy, reliable and noninvasive predictor for early diagnosis and treatment of spinal induced hypotension is important. Ultrasound technology has gained its popularity and dramatic growth of use inside the operating rooms as a non invasive , low cost and rapid manoeuvre. Caval aorta index is a more effective , quick and convenient method for the evaluation of intravascular volume . In the study we will be comparing two groups with group A as comparision group and groupB as control group. A total of 80 American society of anaethesiologists (ASA) physical status 1 or 2 of age group 18 to 60 years will be considered. Reduction in the incidence of hypotension between the groups, total volume of IV fluids required throughout the procedure, number of boluses of vasopressors required, and complications will be assessed.
