Abstract

Objective: To determine the effect of Body Mass Index on depth of Subarachnoid Block and technique of Spinal Anesthesia in Elective Cesarean Section.

Study Design: Prospective longitudinal study

Place and Duration of Study: Combined Military Hospital Rawalpindi Pakistan, From Mar - Sep 2022.

Methodology: A total of 60 participants were randomly distributed in two uniform groups with BMI cut off value of 45 between the two. Age of the patients included in the study was from 18-40 years with single pregnancy planned for elective cesarean section. Under standardized technique, spinal anesthesia was given to patients and various characteristics of block, hemodynamic variables and side effects were recorded.

Results: Total 60 patients were recruited in the research with 30 patients in each group. Mean age of patients in group A was 33.83±4.75 years while in group B was 35.57±2.46 years. Episodes of nausea and vomiting were greater in group B as compared to group A. Hypotension episodes and time to achieve blockade at the level of T6 dermatome between two groups were significant with a p-value of <0.05.

Conclusion: The level of anesthesia achieved in patients with BMI >45 is higher, the onset is rapid with more episodes of hypotension and requirement of vasopressors as compared to patients with BMI <45.
