Hemodynamic Changes Following Regional Anesthesia for Foot Surgeries: A Comparative Study between Ankle Block and Unilateral Subarachnoid Block
Abstract:
Foot surgeries are common surgical procedures performed for various indications ranging from trauma, diabetic foot syndrome, malignancies, abscess drainage, wound debridement, amputation and instrumentation. The aim of this study is to assess and compare the hemodynamic parameters between ankle block and unilateral subarachnoid block for foot surgeries. Fifty adult patients scheduled for elective foot surgeries that met the inclusion criteria were enrolled into the study. They were assigned into two groups of 25 each using computer generated numbers into group A and group S. Group A had surgery under the ankle block using 0.5% plain bupivacaine, while group S had surgery done under unilateral subarachoid block using 0.5% heavy bupivacaine. The pulse rate, systolic blood pressure and diastolic blood pressure were observed and recorded. These variables were analyzed using the Statistical Package for Social Sciences (SPSS) version 25.0 and were presented using relevant tables and figures. Statistical tests of association were performed with a confidence level of 95% and a p-value of less than 0.05 was taken as significant. The hemodynamic parameters; pulse rate, systolic blood pressure and diastolic blood pressure were significantly lower in group S compared to group A at 5-minute intervals when compared to baseline vital signs, (P < 0.05). Ankle block provided better hemodynamic profiles when compared to unilateral subarachnoid block for foot surgeries.
