Dr. V. Balasubramaniaguhan, Dr. K. Anitha

Abstract :

Background and Aims: Regional anaesthesia in obese pregnant patients is associated with numerous complication.Aimof this study is to study the effects of BMI on the Spinal Anaesthesia. Methods : 200 patients who were posted for elective and emergency caesarean sectionwere included and allocated to Group O( obese) and Group NO( non–obese) based on BMI. Results:Incidence of hypotension(>20 % fall from baseline) , height of blockade, time to reach highest level, duration of blockade (sensory level to reach T10 ) and total dose of vasopressor were recorded.Time to reach highest segment was quicker, fall in BP in percentage wise was more and time taken for the sensory blockade level to regress to T10 was more in obese group. Conclusion:It may be concluded that the pregnant patients with BMI more than 25 are prone to get more incidences of hypotension with faster spread of spinal anaesthesia which necessitates a close monitoring.
