CORRELATION OF SYMPHYSIOFUNDAL HEIGHT AND ABDOMINAL GIRTH WITH THE OCCURRENCE OF HYPOTENSION IN CESAREAN SECTION UNDER SPINAL ANAESTHESIA USING BUPIVACAINE WITH FENTANYL AS ADJUVANT – CLINICAL STUDY IN A TERTIARY CARE CENTRE

Abstract

Aim: The objective of this study was to assess the relationship between SFH, Abdominal girth and 1) The highest level of sensory blockade and 2) Occurrence of hypotension.
Methods: 140 parturients under ASA I and II scheduled for elective Cesarean section under spinal anaesthesia in Sapthagiri institute of medical sciences and research center were studied. The SFH and abdominal girth of all parturients had been measured just before spinal anaesthesia. Hyperbaric Bupivacaine 9mg with Fentanyl 12.5 microgram was administered for subarachnoid block. The level of sensory block and the occurrence of hypotension, nausea and vomiting was assessed and treated. Fisher’s exact test, One-way ANOVA and Spearman correlation coefficient were applied to analyze the data.
Results: According to the results of the correlation analysis, there is statistically significant correlation between the SFH and maximum sensory blockade level(correlation coefficient 0.602, p- value -<0.001), Abdominal Girth and maximum sensory blockade level (correlation coefficient 0.781, p- value -<0.001) .There is a statistically significant positive correlation between SFH and number of hypotension episodes (correlation coefficient 0.455, p- value -<0.001), Abdominal Girth and number of hypotension episodes (correlation coefficient 0.221, p- value - 0.009).
Conclusion: In term parturients undergoing Cesarean section, the SFH has a significant positive correlation with the occurrence of hypotension and highest level of sensory block achieved. Abdominal girth also has a positive correlation with the occurrence of hypotension and highest level of sensory block achieved, during spinal anaesthesia.
